Comprehensive service and professional project management are an 足integral part of an ERCO lighting solution.

The ERCO Program features a wide range of LED lighting tools for highly varied applications, ranging from spotlights and recessed luminaires to lumi足naires for the outdoor area.

The Light Factory

ERCO’s core competence is its knowledge in lighting technology. Even the optoelectronic systems and elements for inno vative LED lighting tools are designed and built in-house.

ERCO’s Technical Centre in Lüdenscheid offers a functional arena for the close cooperation of the design, marketing and sales departments. Design seminars are regularly held at ERCO for groups of architects, lighting designers, engineers and students.

ERCO is a specialist producer of lighting engineering hardware and software for architectural lighting. First and foremost, we see ourselves as selling light, not luminaires. This approach, which places the immaterial “software” of light above the physical hardware of the luminaires, has been the trademark of our work for many years. For this reason we like to refer to ourselves as: ERCO, the Light Factory. Light interprets spaces and helps us to perceive and experience them. In this sense, we consider light to be the “fourth dimension” of architecture. Making good architecture even better with light is what we see as our cultural contribu tion and the raison d’être of our activities. Today, ERCO illuminates museums, universities retail chains, churches, airports, hotels, administrative buildings, private residences, parks, squares and much more besides. Irrespective of whether the architectural concept emphasises functionality or presentation, our goal is, and has always been, to find a solution that does justice to the specific use and architectural features of each individual project. In the same way we give consideration to the requirements of human perception and to the need for sustainability and energy efficiency. ERCO’s indoor luminaires, outdoor luminaires and lighting control systems constitute an extensive range of lighting equipment for general, comprehensive, architectural lighting solutions. The luminaire is a lighting tool, a piece of lighting equipment with a particular and practical purpose. The breakthrough of LED technology currently being experienced in architectural lighting is probably the biggest development in lighting technology for decades. ERCO plays a leading role in implementing these advances with practical LED lighting tools. The new technology opens up possibilities for realising efficient visual comfort to a previously unattainable level. With our “tune the light” approach, we develop innovative products and methods for producing, directing and controlling light, enabling designers and users alike to optimally exploit the advantages of LEDs. The aim of this brochure is to explain ERCO’s specific approach and to help to shape a safe and inspirational transition into a new age of architectural lighting.

LEDs: the efficient alternative Developmental focus on optoelectronics

These are exciting times in architectural lighting. With the breakthrough of the LED as a viable light source across a wide front, we are currently experiencing a far-reaching technological upheaval. This is comparable with the transition from analogue vinyl records to digital music on CDs and memory sticks, or from analogue to digital photography. Their enormous potential, both in terms of efficiency and regarding lighting quality and visual comfort, means that light emitting diodes will be the light source of the future. In particular, they are an alternative to incandescent lamps and tungsten halogen lamps which are known to be poor in terms of energy efficiency. It is at such times of change that there is a rise in the requirement for bona fide information, e.g. what are the specific properties of LEDs for architectural lighting? What are their advantages compared with conventional lamps? How do LED lighting tools operate? What factors govern their efficiency in practical applications? What design possibilities do LED luminaires offer for lighting designers and to what extent does this alter design processes and cause paradigm changes? These and other questions are dealt with in this brochure. Additionally, ERCO’s specific approach to the subject matter of LEDs is explained. The first LED-based lighting tools appeared about ten years ago in the form of orientation luminaires in the ERCO Program. In our current range of LED lighting tools, light emitting diodes are no longer used merely as coloured effects or for orientation. They are now 2

suitable for professional accent lighting and ambient lighting and also for high-quality, energy-saving wallwashing. White and coloured LEDs now take up a natural place alongside fluorescent, halogen or high-pressure discharge lamps. This is especially true in the new Quintessence range of recessed luminaires, which features over 350 LED products. Simi larly in established spotlight ranges and in many other luminaire ranges for both indoor and outdoor applications. Our philosophy "Light not luminaires", relates to the quality of light and is largely independent of the technology actually producing it. As such, its validity remains even now, in the age of the LED. Further concepts such as vertical illuminance and efficient visual comfort can be raised to new levels with the help of LEDs. Regarding design terminology, for example, for different light distributions our intention is to maintain maximum-possible continuity. A washlight remains a washlight and a spot characteristic remains a spot characteristic. One thing that will change with the new technology, however, is luminaire data. Both the wattages and the nominal luminous fluxes of light sources have to be interpreted differently. The pure Light Output Ratio (LOR) is of little use when judging the performance of a lighting proposal because it gives little consideration either to human factors of perception such as visual comfort or to the question of how much light arrives where it is required. It seems more prudent to look at the ratio of

the energy consumption and the illuminance ultimately obtained on the target surface. Intelligent, qualitative lighting design is an essential factor in efficient visual comfort with LED lighting tools. The rise of the LED has caused lighting technology to develop further towards optoelectronics, a seamless connection of optical and electronic components. As with existing lighting technology, ERCO now recognises that optoelectronics will be a core competence and a developmental focus in future. ERCO sees that the potential lies in taking generally available LED modules and creating lighting tools that will add value for ERCO’s designers and users alike. The slogan “tune the light” defines competence in production, direction and the control of light. The necessary optoelectronic systems are designed and built in-house. This includes everything from the PCB of the LED module to the complex secondary and tertiary lens systems consisting of collimating and Spherolit lenses through to the software tools for digital lighting control. This allows the potential of the new technology to be fully exploited, not only for increased energy efficiency and resource conservation, but also for greater creative freedom in architectural lighting.

Lighting tools with LEDs run continuously through all of ERCO’s product ranges.

With the Spherolit technology in reflectors and lenses ERCO demonstrates its leading role in lighting technology to fully exploit the effi ciency potential of LEDs.

Without c ompromise: ERCO brings decades of experience in heat management into designing and building maintenance-free LED lighting tools to match the reliability and longevity of LEDs.

DALI-controlled LED luminaires and lighting controls form a consistent, digital lighting network, providing efficient visual comfort and freedom in scenographic design.

Technology Overview Optoelectronics The breakthrough of LEDs to become an important light source has caused the focus in lighting technology to shift towards the combination of optical and electronic elements, i.e. to optoelectronics. ERCO’s competence in design and production in this field is extensive. In order to create innovative products to reach the goal of efficient visual comfort, technologies and processes are continuously being developed throughout the LED’s value-adding chain. Optoelectronic competence means mastering all the new challenges with excellence: from electronic component heat management to the development of efficient optical systems and from optimising control gear and digital interfaces to developing the corresponding tools in the control software.

System design

LED modules By using dedicated PCB layouts equipped with carefully selected LED binnings, ERCO ensures that optimum luminous flux and colour rendition is obtained for each specific lighting task.

Optical systems The optical systems for LED lighting tools are vastly different from those of conventional luminaires. ERCO designs and builds these systems in-house to ensure a perfect match, thereby allowing their full potential to be exploited in terms of efficiency and lighting quality.

System design For rational planning and practical application, ERCO has fully integrated the LED technology into the system design of its existing product r anges. The available range of shapes, light distributions, wattages and colour temperatures is suitably comprehensive.

DALI PLUG+ PLAY

Heat management ERCO places particular importance on heat management. This ensures that LED modules operate within their safe tem perature range, achieving rated life and output for the specified power throughout their operational life.

Control gear LEDs require perfectly matching electronic control gear. Only ERCO’s factory encoded DALI control gear offer plug and play connectivity, i.e. fully automatic recognition in the Light System DALI lighting system.

Lighting control LEDs and digital lighting controls such as Light System DALI are truly made for each other. No other light source can be controlled as flexibly and efficiently as an LED. The user-friendly operation through lighting control allows great scope to design scenographic lighting in the sense of "tune the light", this enables the potential energy saving to be fully realised.

Technology LED modules LED PCB An LED module consists of the individual LEDs soldered onto a printed circuit board or PCB. ERCO sources the LEDs globally from reputable manufacturers, specifying the luminous flux, luminous efficacy, colour rendition, colour temperature (i.e. colour of light) and consistency in mass production. The choice of suitable LEDs and their arrangement on the PCB depends on the actual lighting task. To optimise the overall system, ERCO designs each PCB in-house. This involves using suitable layouts for each separate light distribution and precise mounting points for the secondary lens, while also considering optimum heat dissipation from the LED chips via the PCB to the housing.

PCB for optical projection system The yellow surface coating of the LEDs emitting white light is a fluorescent material for luminescence conversion. Optimised spacing b etween the LEDs assists the heat management on the PCB. The round o penings facilitate the precise and safe mounting of the collimating lens as part of the optical projection system.

PCB for grazing light Grazing light requires a linear light source. The PCBs for facade washlighting are therefore arranged in a line.

PCB for optical reflection Optical systems that direct the light via a light mixer improve effi ciency if the PCB has a high reflectance. For this reason PCBs are painted white and the arrangement of LEDs on the PCB is designed to suit the optical system.

Daylight white and warm white ERCO offers LED luminaires in daylight white and warm white. This allows lighting designers to select the colour of light to suit the material colours and spatial atmosphere or to create cold-warm contrasts.

Binnings The LED manufacturing process results in certain variations in the colour loci of LEDs. LEDs are accordingly sorted into so-called “binnings”. Uniform lighting quality requires the strict selection of components from defined binnings.

Characteristics of LEDs LEDs (Light Emitting Diodes) are semiconductor elements that directly convert electrical energy into light via electro-luminescence. The outstanding characteristics of LEDs include robustness, long functional life and a high luminous efficacy with high potential for further increase. White LED-light is free of ultraviolet and infrared components and therefore has advantages from a conservation point of view. Daylight white LEDs offer higher efficiency, whereas warm white LEDs have better colour rendition quality. LEDs are dimmable and offer high switching stability, making them ideally suited for lighting control and additive colour mixing. Unlike other light sources, RGB LEDs do not produce any transmission losses through colour filters. To exploit the luminous flux of the temperature sensitive LEDs to the full, good thermal management is indispensable.

The relative spectral distribution of the warm white LED with luminescence conversion is closely related to the relative brightness sensitivity of the cone cells of the human eye. The result is high luminous efficacy and good colour rendition.

Spectral distribution The radiation spectrum of warm white LEDs is free of ultraviolet and infrared components and has a reduced blue component. Its relative damage factor for sensitive exhibits is less than for halogen lamps with UV filters, making warm white LEDs recommendable for museum lighting.

RGB LEDs are ideal for mixing highly saturated coloured light. However, the white light from RGB LEDs does not give satisfactory colour rendition quality, making it less suitable for lighting tasks where colour is critical.

Coloured light The saturated LED lighting colours enable a wide variety of mixed colours within the triangle of red, green and blue. LED modules with additional white LEDs, known as RGBW modules, improve the colour rendition for the colours of light with respect to the Planckian locus.

LED manufacture Like microchips, LEDs consist of semiconductor crystals and are produced using similar methods. The production plants build up the semiconductor layer-by-layer on a wafer. The upper and lower layer of the LED chip features an anode or cathode and the light is produced from the zone in the centre. Despite the use of cutting-edge production plants, not all areas of the wafer have the same properties of luminous flux and colour location. The result is that “binning”, i.e. the selection category after cutting the wafer into individual LED chips, becomes essential. ERCO only uses LEDs of the highest grade and with identical characteristics in its luminaires.

Technology LED optical systems Projection: collimating lens The quality of the optical systems greatly affects the overall efficiency of an LED lumi naire. To produce directed light, as occurs in spotlights, ERCO develops their optical projection systems in-house. A collimating lens, as a secondary lens, is the interface between the LED lens on the printed circuit board and the exchangeable Spherolit lenses acting as tertiary lenses. The collimating lens directs the light of the LEDs into a parallel beam in order that the required light distribution can then be formed by a tertiary lens. The principle of total internal reflection in the collimating lens contributes to the high efficiency of the optical system. Decades of experience in injectionmoulded polymers ensure the highest quality levels from our in-house production plant.

Optical principle The light is guided by three elements in an ERCO LED spotlight: the primary lens which is directly mounted on the LED chip and produces a semi-spherical beam, the secondary lens in the form of a collimating lens to create a parallel beam and the tertiary lens in the form of a Spherolit lens. The design

of the tertiary lens determines the actual light distribution for the specific application.

Total internal reflection Due to its shape and material, the collimating lens for narrow spot directs the light with practically no losses using the principle of total internal reflection. This results in optimum light guidance efficiency.

Collimating lens for narrow spot The appropriate colli mating lens is used with LED spotlights and projectors with the narrow spot characteristic. Its function is solely based on the optical principle of total internal reflection, which contributes to the high efficiency of the optical system.

Collimating lens For all characteristics – except for narrow spot – the three-piece collimating lens is suitable for the module with three LEDs. The beam is controlled by total internal reflection at the sides and by the central lens. Precise mounting points result in secure and effective mounting.

Spherolit lens After focusing the beam through the collimating lens, it is the Spherolit tertiary lens that determines the light distribution. This ranges from narrow beams to wide beams and asymmetric light distributions for vertical illuminance.

With extensive experience in optical simula tions, ERCO identifies innovative solutions for new challenges such as the development of highly efficient lens systems. Short distances for optimum quality: photometric laboratories, tool shop and production department for the optical systems are all located on the same site. This allows for rapid comparison of computer simulations, prototypes and fabricated components.

Projection and reflection Conventional point light sources emit light in a solid angle of virtually 360°, whereas the inherent design of LEDs means their light is directed in a solid angle of <180°. The result is reduced losses due to spill light or light emitted towards the lampholder (shown red in the drawing). Furthermore, the higher transmission efficiency of lenses compared to that of reflectors produces a higher light output ratio which results in the greater luminous flux from the luminaire. In practice it comes down to how much light arrives on the target surface. In this respect, the illuminance from spotlights which have similar characteristics can be c ompared over a given distance in lx/W: the principle of projection with LEDs continues to be c onvincing.

Three spotlights with similar light distribution and illuminance on the target surface for comparison: the luminous efficacy of the lamp indicates the efficiency of the light source. The relative luminous flux per watt indicates how much of the lamp’s light is emitted from the luminaire. With spotlights, the illu-

minance per watt indicates the value of the resultant accent lighting. The advantages of LEDs are again clearly evident from this efficiency comparison.

Technology LED optical systems Projection: Spherolit lenses With LED lighting tools for directed light, ERCO uses Spherolit lenses as tertiary lenses to direct the light. In terms of their technology and light distribution, the Spherolit lenses are based on the patented Spherolit reflectors which are well established with conventional light sources. In addition to excellent lighting quality, they also offer many practical advantages for both lighting designers and users. The Spherolit technology is based on dividing a large lens or reflector surface into many individual, three-dimensionally domed facets, each of which directs the light through refraction or reflection. The transmission of light through the polymer Spherolit lens has fundamentally lower losses than with reflection. At ERCO, the manufacturing processes all take place under one roof: from complex calculations and computer simulations to tooling up and final production.

Collimating lens Spherolit lens

LED

Characteristics with Spherolit lenses

Narrow spot To accentuate small objects with high light intensity or to cover large distances between luminaire and object. Beam angle < 10°.

Spot The standard characteristic for highlighting objects of all types, especially to accentuate three-dimensional shape. Beam angle 10°– 20°.

Flood To efficiently illuminate larger objects or to emphasise spatial zones such as a specific area. Beam angle 25°– 35°.

Wide flood To give a flexible, flood illumination of surfaces and spatial zones, especially in retail presentation. Beam angle > 45°.

Oval flood The Spherolit lens, oval flood, has an axially symmetrical light intensity distribution, producing an oval beam of about 30° by 90°.

Wallwash The light distribution of the lens wallwasher is designed to provide very good uniformity.

Toolmaking ERCO has its own toolmakers’ shop featuring state-of-the-art equipment and backed up by decades of experience. This guarantees the necessary precision when machining items such as injection-moulding tools used to make optical elements from polymers.

Assembly The luminaires of the Quintessence product range, such as the directional luminaire shown here, are assembled to order using advanced production principles.

Thermoplastic injection moulding Cutting-edge injectionmoulding machines, qualified employees, high-quality raw materials and careful checking all contribute to the perfect quality of ERCO’s collimating and Spherolit lenses.

Spherolit lenses By designing the shape of each Spherolit lens individually, a wide range of lens characteristics can be created. The parallel incident light is spread to a greater or lesser extent depending on the curvature of the surface. This results in lenses that have different beam angles, ranging from narrow spot to wide flood, yet retain the same overall geometry. In addition, asymmetric spherolites enable oval beams and wallwashing lenses. A common feature of all these beam characteristics is light of the highest quality: the beams are particularly uniform, free of striations and have a clean, slightly soft edge.

Spot The Spherolit lens, spot, has flat Spherolit surfaces producing low dispersion for a narrow beam angle.

Wide flood The wide flood Spherolit lens has the greatest curvature. The wide spread produces a beam with a large emission angle.

Technology LED optical systems Reflection Especially in LEDs where high visual comfort is required ERCO uses optical systems based on the principle of reflection. This is the case in the Quintessence range of recessed luminaires with Darklight reflectors. Here, to provide optimum glare control, the illuminated plane of the diffuser is set back from the plane of the mounting surface. This allows the exact cut-off angle to be defined. Darklight reflectors with Spherolit wallwasher segments produce asymmetric light distributions for energy efficient washlights and double washlights. To meet the stringent quality requirements, ERCO carries out all calculation, design and production work in house.

Light mixer The upper reflector of Quintessence LED downlights is divided into eight segments and is made of mirror-finish aluminium. The reflections within this light mixer ensure the best possible colour mixing from immediately in front of the luminaire especially with RGBW LED modules.

Spherolit wallwasher segment

Darklight reflector

Diffuser The purpose of the diffuser technology is to optimise the visual comfort. The frosted glass diffuser reduces the high luminance of the individual LEDs and disperses this evenly across its surface to reduce the glare. The diffuser technology enables the design and

construction of highquality, energy-efficient washlights.

Indirect step lighting With step lighting, it is imperative that the LEDs are well screened to ensure that there is no glare for people going up the stairs. In the Axis Walklight, the light guidance takes place indi rectly. The LED module is concealed from view.

Spherolit wallwasher To achieve the uniform vertical illuminances required for wallwashing, one segment of the Darklight reflector is provided with spherolites. In the photo, the diffuser has been removed to show the position of the LED module. The patented

reflector technology results in the light on the wall beginning just below the ceiling.

The patented Spherolit reflectors are of pressed aluminium. Their innovative technology requires the highest precision and calls for a new approach both in toolmaking and in the manufacturing process.

The finished Quintessence luminaire is built to order from a combination of LED module and a lower reflector unit. Here, innovative technology such as “Pick by Light” shelves ensure error-free order completion.

Cut-off angle and Darklight technology With their computer-generated contours, ERCO’s Darklight reflectors combine maximum visual comfort with high light output ratio. As long as the lamp is within the cut-off area, there is virtually no luminance on the Darklight reflector – the eye is not dazzled. For optimum visual comfort, the higher cut-off angle is recommended for prestigious rooms with high ceilings or for deskwork. The UGR process (Unified Glare Rating) quantitatively evaluates psychological glare. A downlight with a cut-off angle of 40° and a UGR value of 17.3 provides more visual comfort than an otherwise identical luminaire with a 30° cut-off angle and a UGR of 19.0.

A cut-off angle of 30° (left) provides good uniformity on the floor with a very high lighting output ratio. Luminaires with a cut-off angle of 40° (right) provide higher visual comfort. This can also be seen from the UGR values in the product data sheets. If the observer is

in the cut-off area of the luminaire, the reflector will appear glare free.

Technology Heat management High-power LEDs generate heat just as all other light sources, resulting from the resistance to the flow of current in the semicon ductor. To ensure that the nominal luminous flux and functional life are attained, the identified maximum temperature of the LEDs depletion layer must not ever be exceeded even in continuous operation. ERCO therefore places particular importance on heat management in the luminaire, ensuring that the LED modules operate below the critical temperature range in order that they produce full power output throughout their entire functional life. ERCO uses passive heat sinks, which are maintenance-free and reliable, and unlike active systems do not consume any additional energy. Their thermally optimised design minimises the drop in luminous flux, which occurs with LEDs whenever they heat up.

Heat dissipation through the housing With spotlights, the heat can be efficiently dissipated away from the LED module via the housing. The cast-aluminium material gives the luminaire good thermal conductivity and a high thermal capacity. The large-area connections between the rear of the housing and the LED’s PCB ensure good heat conduction.

Thermal coupling The LED module is permanently bonded to the spotlight housing, creating ideal conditions for heat dissipation. This is one fundamental advantage of such integrated LED solutions over all other types of retro-fitted designs.

Dissipation through heat sink plate In certain housing shapes, such as with Cylinder surface-mounted luminaires for the outdoor area, it can be necessary to fit an additional heat sink plate between the LED module and the lumi naire housing to improve thermal coupling. Here too, the construction and dimensioning are based on thermal simulations which are part of the design process.

Heat dissipation via cooling fins The correct design of cooling fins ensures that the recessed luminaires have an ideal thermal balance. The position, length and thickness of the cooling fins are thermally simulated in the development process to determine the optimum design for efficient heat dissipation.

Ribbed housings The cooling fins on the rear of the Powercast housing increase the surface area and enable the LED’s heat to be optimally discharged through radiation and convection.

-56° Drehung

Thermal radiation from LED luminaires In high-power LEDs, as with other lamps, heat is generated because of the flow of current. This heat is largely dissipated to the rear of the luminaire via the PCB and via the coupling to heat sinks or the luminaire housing. On the positive side, the light of white LEDs is free of infrared radiation, which

means that the beam does not warm up the target object. This aspect is particularly relevant for museums as, for conservational reasons, placing a thermal load on the exhibits is undesirable. The same applies to the lighting of heat sensitive foodstuffs.

Thermal radiation from luminaires with lowvoltage halogen lamps As thermal radiators, lowvoltage halogen lamps generate light via a glowing filament, causing heat emission in all directions. Compared with LEDs, the electromagnetic spectrum of low-voltage halogen lamps has a higher proportion of infrared.

This means that infrared filters are usually necessary for the illumination of artworks, which reduces the efficiency.

Thermal simulations Beginning with the development phase of LED luminaires, the ERCO engineers produce thermal simulations to optimise the heat management. Tests in the measurement laboratory take place to confirm the accuracy of the detailed simulations and guarantee excellent light output when the finished product is in use.

Functional life of LEDs Good heat management allows the potential of LEDs to be used at full power over the entire functional life. The depletion layer temperature, which is measured between the LED’s two conductive layers, is the critical parameter for the heat management. If this temperature rises above a critical value, the first thing to be reduced is the functional life. If the maximum value is exceeded, the LED will be completely destroyed. The possible reduction of the luminous flux to 70% and the perfect function of 50% of the LEDs are entered into the equation to calculate the nominal func tional life. ERCO designs the heat management of its LED luminaires such that a functional life of 50,000 hours can be expected (graphic source: Philips).

Technology LED control gear The ability to specify and develop the right control gear is an essential part of ERCO’s competence in optoelectronics. Control gear precisely tuned to each individual LED module transforms the mains voltage into direct current at the appropriate voltage and constant current. Another function performed in the control gear is the dimming of LEDs using the principle of pulse width modulation. Through the factory encoding of the c ontrol gear, ERCO’s DALI-compatible LED luminaires offer plug and play connectivity for user- friendly commissioning. The control gear of varychrome LED luminaires is programmed with an electronic colour compensation factor to allow for the manufacturing t olerances of LEDs. Because ERCO develops its own in-house control gear, compact and specific solutions are possible that optimally fit the luminaire design.

Luminaires with DALI control gear Using factory encoding, the Light System DALI automatically recognises ERCO Light Clients, i.e.

luminaires with DALI control gear, offering true plug and play connectivity.

able versions with trailing edge technology.

t LEDs are dimmed by changing the pulse width. This allows LEDs, in contrast to high- pressure discharge lamps and fluorescent lamps, to be infinitely dimmed between 0 and 100%. The reduction in energy consumption is directly proportional. Both colour temperature and colour rendition remain constant.

Control gear encoding Commissioning many luminaires can be time consuming if the assignment to the colour channels is performed manually. This is especially the case when using RGB luminaires, which have three control gear addresses to control the colours. To optimise user comfort and reduce the work load when commissioning, ERCO’s engineers have developed the concept of encoding the control gear. Every Light Client, i.e. every DALI-compatible luminaire from ERCO is identified by an article number and a serial number. This includes details of the lamp and control capability as well as the position of the control gear for assigning the RGB addresses. After electrically testing the luminaire as part of the quality management in the production department, the software then writes the specific information into the control gear. This means that, when commissioning the system with the Light Studio software, the commissioning engineer can automatically view a clear presentation of all details and can use predefined light scenes to check and install the lighting system and enable its operation.

Colour compensation with varychrome LED luminaires Due to the manufacturing process, LEDs vary in terms of their luminous flux and dominant wavelength. Even with ERCO’s stringent specifications for the selection by binning and consistent DALI control values, it is possible that the light colours produced by RGB colour mixing can deviate visibly from one luminaire to the next. To ensure colour constancy, each colour compensated ERCO luminaire is individually measured and adjusted in the factory. Special software calculates the compensation factors which are permanently stored in the control gear. The user is therefore provided with lighting tools that always reproduce exactly the same colour of light.

Control gear Coding - Article number - Luminaire ID - Lamp index - Control capability index - Control gear position

Coding for greater user comfort The Light Clients are encoded with a unique code in the DALI control gear. When powering up the system, the Light System DALI automati cally recognises the lumi naire type and provides the relevant information and functions.

Encoding and checking In addition to the article information, the software also writes the individual compensation factors into the respective control gear as per the measurements for colour compensation. This is an important aspect for achieving perfect lighting quality with RGB LED luminaires.

Electromagnetic compatibility Conversion to electromagnetic energy takes place through the control gear. For this reason all luminaires undergo an electromagnetic compatibility analysis at the design stage to ensure that they do not unintentionally influence o ther devices with electronic components.

The human eye is capable of noticing even the slightest deviations in hue.

The advantage of colour compensation with varychrome luminaires is therefore particularly useful in applications requiring high consistency, such as coloured wallwashing.

Technology Lighting control Control characteristics of LEDs The optimum switching and dimming behaviour of LEDs makes them ideal for integration in electronic lighting systems such as Light System DALI. LEDs have absolute switching stability and are capable of hot re-strike. They can be continuously dimmed down to 0% without any of the negative effects associated with other lamps, such as the effect on lighting colour, colour rendition or functional life. For this reason the majority of ERCO’s LED lighting tools are also available as Light Clients, i.e. with DALI-compatible control gear. Individually addressable luminaires, powerful software and a wide variety of interfaces for switches and sensor technology all come together in Light System DALI, to combine scenographic lighting with efficient visual comfort.

Dimming The brightness of LED luminaires can be continuously adjusted. The master dimming function in the Light Changer+ also allows the overall brightness of a s elected light scene to be regu lated. Unlike other lamps, colour temperature and colour rendition remain constant with LEDs.

Colour temperature Light Clients with the RGBW LED module are displayed in Light Studio with the 4-channel vary chrome attribute. The colour temperature can be infinitely adjusted over a wide range using the relevant slider control in the software.

Coloured light For use with DALI- compatible varychrome technology luminaires, Light Studio features a colour wheel. This familiar and user-friendly control for infinite RGB colour mixing provides an intuitive and interactive means of selecting the light colours. It relieves the user from the tedious task of having to input separate dimmer settings for the individual colour components.

DALI PLUG+ PLAY DALI plug and play Every Light Client, i.e. every DALI-compatible ERCO luminaire, is supplied by the f actory with a digital code pre- programmed in its DALI control gear. The lumi naire ID contains the article and serial numbers for the special userfriendly functions when commissioning, programming and operating Light

System DALI. The Light Studio software identifies the type of luminaire and provides the appropriate information and functions.

Control of varychrome rings Quintessence recessed luminaires with vary chrome rings are designed for user-friendly control via Light System DALI. In this type of luminaire, the primary light source and the varychrome ring form two distinct technical lighting systems each with their own dedicated DALI control gear. As a Light Client, the luminaire is factory encoded with a unique luminaire ID, allowing the Light Studio software to automatically recognise the luminaire as a unique entity and to clearly assimilate the data. The colour of light in the varychrome ring can be easily adjusted using the colour wheel in the software and dynamic progressions can be programmed in just a few mouse clicks.

Control gear varychrome ring In luminaires with vary chrome ring, the light for the varychrome ring is adjusted separately. For instance, dimmed light can be selected for the ambient lighting effect and a ring of coloured light as a decorative attraction.

Collaboration between IT engineers and designers at ERCO has r esulted in a powerful package of hardware and software for user-friendly lighting control.

Light Studio software The Light Studio software makes it easy to set up lighting installations with Light System DALI and makes its complex functions available in a user-friendly format. It consists of five modules: The Light Master module is used for editing and managing the light scenes. The Light Book is used for organising and structuring Light Studio projects. The Light Timer module allows light scenes to be recalled at pre-defined times. The Light Sequencer is a tool for defining the chronological progression of light scenes. Finally, the functions in the Light Keeper module support the user in planning maintenance and help utilise the potential for saving energy.

Control gear luminaire

Luminaire

To enable a separate adjustment of brightness and lighting colour, this type of luminaire has two separate sets of DALI control gear. Through these encoded control gear units the luminaire is recognised as an entity by the system, to simplify programming.

Pre-defined light scenes make it easier for the lighting designer to inspect the lighting installation. The Light Studio software has a clear user interface, enabling rapid configuration of light scenes through to time-controlled light sequences.

The Light Changer+ PC software makes the user-interface of a Light Changer+ available to operate Light System DALI on a PC.

The special functions in the Light Keeper module provide users with a particularly convenient means to realise the energy-saving potential of their lighting instal lation with the help of intelligent lighting control.

Technology Lighting control Energy saving through lighting control Sensor technology gives Light System DALI systems the capability to adapt to changing influences in the surroundings. Via the Light Studio software, the relevant light scenes can be conveniently programmed and made dependent on the readings from the sensors. In this context, DALI-compatible LED lighting tools, both through their high luminous efficacy and through their optimal controllability, contribute to lighting solutions with efficient visual comfort.

The energy-saving functions of Light Studio graphically display the connected load of the light scenes in order to clearly identify the potential for energy saving.

Temperature-dependent lighting control In order to limit the thermal load with regard to the air-conditioning, dimming of the lighting is made dependent on temperature.

External sensor

Indoor sensor

Daylight-dependent control A typical application for the analogue inputs is the daylightdependent control. An external sensor controls an analogue v alue in response to daylight conditions. The sensor's range of values allow up to 12 switching thresholds to be set in Light Studio. The sensor’s analogue value triggers the appropriate scene or sequence when a threshold value is exceeded. One application for external sensors: daylightdependent control of museum lighting.

Sensor technology and energy saving regulations In many parts of the world legislation is currently being introduced to save energy in buildings. Such provisions already frequently prescribe the use of presence detectors and constant light regulation to defined reference values. They therefore require the installation of an appropriate lighting control system as a prerequisite for the practical implementation. The result is that efficient visual comfort through intelligent lighting control is made a mandatory part of lighting design.

Connection of media technology Ethernet can be used to connect the Light System DALI with standard media technology controls. Many functions of Light System DALI can be controlled using a documented programming interface. Media controls from the manufacturer AMX are compatible with Light Studio.

Technology System design Taking system design to its logical conclusion is a characteristic feature of ERCO products. LED luminaires are therefore never seen as solitary products, but are fully integrated into the systematic structure of the overall product range. This allows the designer to use LED lighting tools for many different lighting tasks and to combine them seamlessly with conventional products. Efficient and rational planning is ensured by consistent product range structures with comparable light distributions and by uniform terminology but also by defined interfaces such as the adapter for track-mounted spotlights. The DALI technology gives our product system an additional virtual software level – on which all ERCO Light Clients can be conveniently networked.

Characteristics With characteristics ranging from narrow spot to wide flood, the light distributions of the LED luminaires follow the established structure of ERCO’s product range and offer a wide scope for design. LED floodlight and wallwasher characteristics are currently being developed and replaceable Spherolit lenses provide additional flexibility in selected luminaires.

System design has been a characteristic feature of ERCO’s product structure for decades. Today, the design and development process not only covers the construction of the lighting technol ogy and the design of the luminaire’s shape, but also includes the conception of p roduct groups, of product systems, of production

Colour temperature and coloured light By using deliberate contrasts between warm white and daylight white light, the lighting designer can create subtle contrasts and atmospheres while also responding to specific materials. Furthermore, lighting tools for vibrant effects with saturated colours are also available in the form of varychrome LED luminaires.

Lumen categories Due to the high – and continually improving – luminous efficacy of LEDs, it is particularly important when planning to think in terms of lumen categories. The LED luminaires in the ERCO product range cover a wide range of lumen categories and therefore offer an appropriate solution for a large number of lighting tasks.

p rocesses and of digital interfaces, plus extensive technical documentation for each product.

Light distribution A wide selection of photometric characteristics lays the foundation for qualitative lighting design and efficient visual comfort. ERCO’s LED luminaires cover all the essential characteristics: energy-efficient vertical illuminance with various wallwashers, ambient lighting with downlights and accent lighting with direc tional luminaires.

Double washlight Double washlights are offered for uniform illumination of parallel walls as well as the floor in hallways. The light is controlled using a darklight reflector which has two integral Spherolit reflector segments.

Differentiated lighting design requires various lighting tools that each offer the optimum lighting quality and efficiently complete their task.

Directional luminaire Highlighting is provided by directional luminaires. The beams can be tilted up to 30° from the vertical axis and rotated through 360°.

Lens wallwasher Special lens reflector systems ensure highly uniform wall illumination. The darklight reflectors which are visible from below are glare-free.

Systems The principles of system design make a convincing argument not only from the design point of view but also from the technical perspective. Conventional spotlights on ERCO track can be easily supplemented with LED spotlights or replaced altogether. Within an ERCO product group, LED spotlights can be combined with conventional spotlights with design consistency. The Quintessence range of recessed luminaires offers comparable flexibility thanks to the uniform mounting rings. Updating with efficient LED technology or changing any other photometric characteristics is a simple matter due to the modular system.

Spotlights and track Innovative LED spotlights can be simply installed into existing ERCO track installations.

Quintessence The modular system of Quintessence is based on uniform mounting rings and mounting frames. This enables luminaires with different characteristics to be installed. Subsequent alterations such as replacing a lowvoltage halogen downlight with an LED directional luminaire do not

Luminous flux (lm) The luminous flux is the total light power of a light source over the visible spectrum taking the varying spectral sensitivity of the eye into account, as given by the V(λ) curve. This means that a radiant flux in f requency r anges where the eye is less sensitive will result in relatively lower luminous flux values. LEDs are being developed towards increasingly higher connected loads and luminous fluxes. This makes them increasingly effective for lighting tasks that require higher luminous flux. For this reason the selection of suitable lamps and wattages is recommended through the use of lumen categories.

Economic efficiency: Luminous efficacy and functional life The economic efficiency of a lamp depends on its luminous efficacy and functional life. As a measure of the efficiency of a lamp, the luminous efficacy is the ratio of the emitted luminous flux in lumen to the expended electric power in watts. With their high luminous efficacy and long functional life, LEDs represent an important alternative for energy efficient planning. In contrast to conventional lamps, there is still much developmental potential to increase the luminous efficacy of LEDs. This means that when calculating the luminous flux or illuminance, it is important to use current figures for the luminous efficacy of LEDs as opposed to the wattage of the LED module.

Colour of light The colour of light from a lamp depends on the spectral distribution of the emitted light. In lighting design practice, white light is categorised into colours such as warm white, neutral white or daylight white. Warm white lamps bring out the red and yellow spectral range, whereas blues and greens, i.e. cool colours, are emphasised under daylight white light.

Colour rendition The spectrum of a light source determines the colour rendition. A continuous spectrum provides optimum colour rendition, whereas band spectra result in poorer colour rendition.

Unified Glare Rating (UGR) The Unified Glare Rating (UGR) procedure is an approach to quantify the visual comfort of a luminaire. It describes the psychological direct glare of luminaires. The UGR reference value is calculated for a standard space. The graduation value indicates the limiting angle at which the luminaire has an all-round luminance of < 1000cd/m2 or less. For efficient visual comfort, the aim is to achieve a balance of high Light Output Ratio and good Unified Glare Rating.

Light Output Ratio (LOR) To compare the lighting technology of luminaires, the Light Output Ratio (LOR) is often used. However, a higher LOR only allows lim ited conclusions to be drawn about the suitability of a luminaire because it does not consider either visual comfort or how effectively a luminaire directs its light onto a target surface.

Power (W) and luminous flux (lm) Power consumption is used to compare the electrical energy requirement of luminaires. The lamp rating identifies the power, while the luminous flux is the emitted light. The active power describes the actual energy used, which is reduced when dimmed.

There are three aspects that determine the efficiency of lighting. While the luminous efficacy of a lamp and the LOR provide quantitative measures, it is the issue of how effectively a luminaire fulfils its lighting task that is the essential qualitative measure.

Efficient visual comfort Lighting concepts

Low-voltage halogen lamps For differentiated lighting of a prestigious reception area, downlights are used for the ambient lighting, wallwashers for spatial division and directional luminaires for highlighting the artworks. This was previously a typical application area for low-voltage halogen lamps when aiming to satisfy criteria such as brilliance, warm colour light, very good colour rendition and dimmability.

LED Luminaires with 28W LED modules in warm white are comparable in terms of luminous flux to 90W low-voltage halogen lamps and, like the latter, also provide brilliant light together with good colour rendition. For an identical lighting concept and comparable illuminance, the LEDs can give a 65% energy saving. In addition, the maintenance costs also cease to apply. Even if used for 10-hours a day every week, LED luminaires can be expected to return a functional life of about 20 years; at which time, half of the luminaires will still be emitting at least 70% of their luminous flux.

ERCO lists specific criteria for the lighting design depending on the partic ular characteristic, e.g. with downlights this is the reference value P* for the connected load, the Light Output Ratio (LOR) and the Unified Glare Rating (UGR). For washlights, the average vertical illuminance is listed, while with directional luminaires it is the illuminance dependent on the distance and beam diameter.

Low-voltage halogen lamps: horizontal ambient lighting A conventional approach to lighting design for a reception area, for instance, will primarily aim at achieving sufficient horizontal ambient brightness. Such lighting, which is directed at the floor or working planes, is less concerned with the spatial quality of the surrounding vertical surfaces, despite the fact that these occupy a large proportion of the field of vision and contribute to the brightness impression.

LED: differentiated lighting design with wallwashing If, in the context of a qualitative, perception-orientated lighting design, the human field of vision is considered, then the potential of vertical illuminance for creating a bright spatial impression can be utilised. The use of wallwashers or double washlights for hallways would then provide an ideal solution. Directional luminaires accentuate the working planes to produce pleasant workplace lighting. By using LEDs in this way, a higher lighting quality can be combined with lower e nergy consumption.

This lighting design can be optimised in two directions: firstly, changing the lamps from lowvoltage halogen lamps to LEDs. Secondly by changing the lighting concept from horizontal ambient lighting to d ifferentiated, qualitative lighting design. As tools for vertical illuminance to provide efficient visual comfort, double washlights and lens wallwashers with LEDs are used.

Efficient visual comfort Lighting concepts

High-pressure discharge lamps: horizontal ambient lighting A standard solution for a boutique would be downlights with highpressure discharge lamps in a uniform grid pattern, providing high luminous efficacy and brilliance. With their characteristic beam scallops, the downlights clearly divide the wall into a brighter lower section and a darker upper zone.

LED: differentiated lighting design with wallwashing A qualitative, perception- orientated lighting design can create a more attractive shop ambience by emphasising the essential aspects. For instance, vertical elements dividing the room can be emphasised using uniform wallwashing or the products can be highlighted using accent lighting. Differentiated lighting design with LED lighting tools results in efficient visual comfort: a higher lighting quality and yet with slightly reduced electricity consumption – even when compared with the highly efficient high-pressure discharge lamps.

Even today, LEDs have a luminous efficacy comparable with that of the highly efficient metal halide lamps. Qualitative, intelligent planning involving a differentiated use of LED lighting tools gives the LED concept an advantage – and this will further increase if the potential benefits of lighting control is entered into the equation.

Compact fluorescent lamps: horizontal ambient lighting At first glance, a grid of downlights with compact fluorescent lamps may seem to be an efficient, rational lighting concept for a waiting area. Yet, here too, there is considerable potential for increased efficiency through qualitative lighting design and a differentiated use of LED lighting tools.

LED: differentiated lighting design with wallwashing Even in comparison to classic lighting solutions with compact fluorescent lamps, LED luminaires still make a convincing choice when used in a differentiated lighting design. The wallwashers heighten the spatial impression and give a feeling of spaciousness. The higher reflectance of the bright walls, compared to the usually darker floors, is used to advantage in this case. A wide grid of downlights ensures sufficient ambient lighting in the seating areas and also the number of luminaires to be minimised.

With the LED solution, reducing the number of downlights in favour of lens wallwashers not only produces improved lighting design, it also contributes to energy saving.

LED applications

The current status of LED technology, as implemented in ERCO’s LED-based lighting tools, allows a wide range of applications in architectural settings in both indoor and outdoor areas. Successful projects with ERCO LED luminaires confirm the fundamental technical and planning concepts, making efficient visual comfort a tangible reality.

Optimum conservational conditions for valuable graphic artworks, made possible with individually dimmable Optec LED spotlights (museum kunst palast, Düsseldorf).

Optec LED spotlights in daylight white and warm white allow for designs with contrasting colour temperatures. These are gentle on exhibits and also reduce the running costs (Brothers Grimm Museum, Steinau an der Straße).

The pathway and step lighting with Axis Walklights and Midipoll bollard luminaires provides safety and an agreeable ambiance around this p rivate house in Sweden. LEDs provide maintenance-free operation, switching stability and minimum power c onsumption (private house, Kalmar).

Midipoll bollard luminaires with LEDs have proven themselves even under harsh environ mental conditions. In contrast to other light sources, the luminous flux of LEDs does not decrease in cold conditions.

Lighting projects in public spaces which lay claim to meeting the demands of sustainability and resource conservation are ideal for LED technology. As is the case with this scenic lighting installation for a bridge in Norway using Powercast LED projectors (Egersund Lygre bro, Egersund).

Lighting tools in the indoor area Spotlights, floodlights and wallwashers Cantax

Cantax spotlights combine state of the art lighting technology with the clean lines of Naoto Fukasawa’s minimalistic design. LEDs in white and in varychrome technology with Spherolit lens offer efficiency and uniformity in their lighting effect.

Emanon

Developed by designer Yves Béhar, Emanon is particularly well suited for retail outlets and shop windows. Emanon spotlights offer considerable scope for scenographic lighting concepts.

Optec

The name Optec refers to a spotlight group with the striking design feature of a separation between the light head and control housing. The Optec product group is particularly economical and is intended for the illumination of salesrooms, restaurants and museums.

DALI plug and play Every Light Client, i.e. every DALI-compatible ERCO luminaire, is supplied by the factory with a unique code pre- programmed in its control gear. This luminaire ID is the key for the special user-friendly functions of Light System DALI.

The Light Studio software identifies the type of luminaire and provides the appropriate information and functions.

DALI PLUG+ PLAY

Lighting tools in the indoor area Recessed spotlights Quintessence

Quintessence recessed spotlights form a com prehensive range of products for ceiling- integrated accent lighting. The rotatable and tiltable spotlights can be flexibly aimed within the room. Spot and flood characteristics are available.

The twin mounting frame allows two Quintessence luminaire inserts to be mounted as a unit. This for instance allows a spot directional luminaire to be combined with a wallwasher.

Quintessence recessed spotlights and recessed luminaires all use the same mounting ring or mounting frame. In contrast with the flushmounted version, the tilted luminaire head on the regressed version does not protrude below the ceiling.

To enable individual adjustment to suit the specific lighting task, a range of filters and lenses are available.

Recessed luminaires Quintessence

Designed for efficient visual comfort, Quintessence makes it possible to achieve maximum efficiency, lighting quality and functional life. The modular structure of the product range includes a wide range of light distributions, while focusing on efficient vertical illuminance. Many different versions of mounting details can be created and combined.

Quintessence recessed luminaires in round or square formats allow the ceiling appearance to be designed to suit the architecture and the style of the interior.

The standard version of luminaire trim of Quintessence creates a direct transition between the ceiling and the lumi naire. The shadow gap separates the luminaire from the ceiling surface. The varychrome ring around the luminaire produces a decorative effect for styling the ceiling a ppearance.

Lighting tools in the indoor area Wall-mounted luminaires Floor washlight

Floor washlights are ideally suited to provide safe lighting of t raffic routes. The wide light distribution ensures good orientation. They can be mounted flush with the wall or with a covering ring or frame to define the extremity of the luminaire.

For a uniform luminance gradient and a high luminaire maintenance factor, the design includes a diffuser as safety glass.

Recessed floor luminaires Nadir IP67

Light sources in the floor are unusual. The result is that Nadir luminaires attract a lot of attention. Grazing light, dramatic highlights and informative lighting can be implemented particularly well with Nadir. Rated at IP67, the high protection mode housings ensure the luminaires are particularly resistant to dirt and moisture. As grazing light wall washers, Nadir luminaires can emphasise wall surfaces and their textures using a wide light distribution.

Directional luminaires are used for accent lighting on objects or architectural details. Their rotationally symmetrical light distribution produces a visible narrow beam when mounted close to the wall.

Lighting tools in the outdoor area Projectors and floodlights Powercast 足projectors

Economic efficiency and flexibility are brought together in the Powercast product range. The lumi足 naires offer lighting solutions for the 足specific illumination of facade details, signs or vegetation.

Powercast LED projectors are available in the three light intensity distributions, spot, flood and wide flood, enabling accent lighting or floodlighting.

Grasshopper

Due to its compact housing design, the Grasshopper luminaire is ideal for discreet 足applications accentuating facade details, trees and plants.

The projectors have a robust, multiply powder coated aluminium housing and their lockable hinges ensure that they can be accurately orientated.

Grasshopper projectors are available either with white LEDs or in DALIcontrolled varychrome technology.

Lighting tools in the outdoor area Facade luminaires Kubus

A recessed housing is available for flushmounting the pathway luminaire in walls.

The Kubus LED facade luminaire offers the ideal solution to d iscreetly highlight details and entrances. This luminaire emits directed grazing light across a facade.

The lens system of the LED floor washlight for pathway lighting spreads the beam to produce a distinct oval pattern. The Softec lens as lamp cover thus produces a soft luminance gradient.

Axis Walklight

Maintenance-free and highly efficient LED technology is also found in the DALI-compatible Axis Walklight step-mounted and pathway luminaires. The complete screening of the direct components of light ensures optimum visual comfort.

Focalflood

Energy efficiency and maintenance-free operation: these are the features of the Focalflood facade luminaire. The DALI-compatible LED luminaire has digitally addressable control gear and a narrow-beam light distribution to provide a uniform illumination of large areas. When the luminaire is directly mounted on the surface, the light grazes the facade or ceiling, reducing light pollution to a minimum.

Lighting tools in the outdoor area Open area luminaires Midipoll

As well as projecting a circular beam, Midipoll also emits grazing light down onto its own cruciform-section bollard profile which acts as a space-defining element. This bollard luminaire is characterised by Dark Sky technology, longevity and economic efficiency.

Kubus

Recessed luminaires Lightcast

Downlights The Lightcast p roduct family represents an energy efficient ambient lighting for use in outdoor areas such as entrances or passages. Its robust cast-aluminium housing is designed to withstand harsh environmental conditions.

Lens wallwasher The lens wallwasher produces an asymmetrical light distribution for uniform illumination of vertical surfaces. It is available with high- power LEDs in warm white or daylight white.

Directional luminaire The narrow beam angle allows building details or sculptures to be perfectly accentuated. This lighting technology module can be tilted at up to 15° within its housing.

Lighting tools in the outdoor area Surface-mounted downlights Cylinder

This luminaire has the same photometric properties as the Lightcast series, but has a cylindrical, cast-足aluminium housing for surface mounting. The luminaire is primarily designed for use in transition between indoor and outdoor areas.

In-ground luminaires Tesis IP68

Lens wallwasher The Tesis lens wallwasher is ideal for a highly uniform brightness distribution across a facade. The Darklight technology 足prevents the eye from being dazzled outside the cut-off angle either by the lamp itself or by reflections in the reflector.

Recessed floor luminaire In-ground luminaires are available with 足maintenance-free and energy-efficient LEDs in warm white, daylight white or varychrome. They attract considerable attention and are used to delineate pathways and architectural lines.

Lighting tools in the outdoor area In-ground luminaires LED orientation luminaires IP68

Pathways and open areas can be clearly identified with these orientation luminaires using white or coloured light. Scratch-resistant glass and stainless-steel construction ensure many years of problem-free service. The use of diffusers and refractors ensure that they are visible even in bright surroundings. The floor washlights produce a directly emitted, asymmetric light distribution.

Lighting tools Lighting control The ERCO Light System DALI lighting control system takes an innovative approach w hereby intelligently applied DALI (Digital Addressable Lighting Interface) technology for individ ually addressable luminaires is combined with the ERCO Light Studio software to form an integrated system for scenographic lighting and efficient light management. Together with ERCO’s extensive range of DALI-compatible luminaires for indoor and outdoor areas and ERCO’s DALI track. The combination enables the potential of lighting control to be realised simply and economically in practical applications as never before. This relates to both scenographic lighting effects and intelligent light management to save energy. Installation work is reduced enormously compared to other lighting control technology: DALI technology integrates the switching and dimming functions in the luminaire, i.e. in the control gear. The installer simply connects the twocore control line in any suitable topology. The power supply to the luminaires is constant and independent of the DALI wiring.

Light System DALI The Light Studio is the central control software used to control the Light Server, which is the interface between software and luminaires. The program is subdivided into four modules covering all areas of lighting control.

Light Changer+ Stored light scenes and timer programs can be recalled by the Light Server via the Light Changer+. The Light Changer+ has a user-friendly touch screen for menu navigation. An On/Off push- button is provided to switch all Light Clients on or off.

DALI PLUG+ PLAY

Plug and play Most ERCO LED lighting tools are also available as Light Clients, i.e. with DALI-compatible, factory encoded control gear. They are automatically recognised by the Light System DALI (plug and play).
