Three downlights with strong identities
2
A holistic attitude to light Louis Poulsen has always had a unique approach to lighting. We do not make light bulbs. We interpret their good and bad characteristics in a way that ensures our fixtures fulfil our strict requirements for: Good lighting for people. Our lighting philosophy is integrated into all our products. Important parameters such as no glare, good colour rendering and comfortable ambience are therefore elements in our final fixture designs. We care about people’s well-being, and want them to feel comfortable working or relaxing in the light from our fixtures. We have an attitude towards light – an attitude which aims to give you an experience of comfort and ambience.

LED – a major step in the right direction Daylight
- and a true rendering of reality The LED light source is still being developed, but its qualities are already come so good that it provides a worthy alternative to many conventional light sources.
3000K
Louis Poulsen supplies LED light sources in two colour temperatures – 3000K and 4000K. Blue light makes light seem more pure and clear. Reducing the quantity of blue light results in a warmer tone. An incandescent lamp has a colour temperature of about 2600K. LED light sources are also ideal for dimming. They can be dimmed smoothly while maintaining their colour temperature.
4000K
LED light sources are also excellent at rendering the colours of nature. This is clear from the continuous spectral curves, showing smooth transitions between red, yellow, green and blue.

beat
a lighting workhorse that blends into any setting Beat LED is an update of Louis Poulsens downlight series which is available in a wealth of variants and light sources. It is a versatile lighting workhorse, which the LED version extends into an energy efficient solution suited to a wide range of lighting applications. With its wide range of accessories, Beat’s identity helps highlight the image and uniqueness of an architectural context. The light distribution or decor components attach to the fixture via a simple magnetic system – requiring no tools.
7
Designed for easy installation and maintenance Beat is easy to install in ceilings. Simply pull down the three spring clamps and tighten them against the ceiling panel, and the narrow ring ensures a close and stable fit against the ceiling. Beat is available with an external driver, making for easier installation, as this can be installed where there is limited space above the ceiling. The efficient heat sink on top of the fixture conducts heat away from the light source, ensuring good efficiency and extending its lifetime.

Ultra-minimalism increases versatility Beat is available with a wide range of accessories. If it is only to serve as a downlight, the narrow white edge makes the Beat fixture a stylistic and simple way to create lighting in harmony with the style and architecture of the setting. Beat has been developed to blend in equally with coffered ceilings, or large flat ceiling surfaces. A discreet white ring on the ceiling surface is the only visible feature. The highly positioned light source significantly reduces ’passing by glare’ and the matt reflector controls the luminance, ensuring a soft diffuse light which is perceived as comfortable, whatever its colour temperature.

A brilliant idea re-expressed Strata LED is an updated version of Alfred Homann’s successful Strata concept. Strata was designed in 1979 in connection with a major renovation project in Nyhavn, Copenhagen. The project required an integrated ceiling fixture for rooms with low ceilings. Alfred Homann conceived a brilliant detail for this fixture. He made the top surface of the rings concave, so that some of the primarily downward directed light could be reflected back on to the ceiling. This forms a decorative circle of light on the ceiling around the fixture which had two effects: 1. It created the optical illusion that the ceiling was higher than it was. 2. It smoothed out the differences in luminance between the fixtures and created attractive lighting on the ceiling surface.
17
The ceiling becomes part of the room Alfred Homann’s Strata fixture enabled him to integrate the ceiling as a visual element of the three-dimensional perception of the space. Arne Jacobsen had the same effect in mind when he created the Munkegaard design classic.

The LED light source creates a different kind of light Whenever Louis Poulsen updates a technical design, great care is taken not to change the lighting intent of the original product. However updating the light source not only involves employing a new light source, but also incorporating more stringent modern requirements, for example in relation to energy consumption. Light from LED light sources is perceived as clearer and more defined, changing the perception of Strata in many ways. The delineations are more stringent and the fixture appears brighter, primarily because the LED light source has a continuous spectrum distribution, emitting more light in the cool spectrum than a compact fluorescent lamp. A different visual impression of the ceiling surface is created and the integration between the ceiling and fixture becomes more uniform.
21
Strata Maxi Light features: The light distribution is diffuse and symmetrical. The white reflector ensures a soft pleasant light. The rings reduce the angle of glare and uncomfortable passing-by glare. The concave top surfaces of the rings reflect some light towards the ceiling, providing the illusion of higher ceiling height.

zirkon
aesthetic minimalism Zirkon was originally developed specifically for Grundfos´ head office by architects C.F. Møller. Zirkon is designed for use as a general ceiling fixture for corridors, etc. Zirkon has a precise, monolithic diffuser. The fixture is characterised by its attractive bright disc, which conceals any hint of the light source outline.

Superlative minimalism - harmonic presence A polycarbonate disc beneath a downlight. It could hardly be more simple, but focus on the details makes Zirkon something special. The suspended polycarbonate disc appears to float as it elegantly illuminates the ceiling surface. The disc achieves its characteristic look through the space which arises between the bright centre, ringed by two different illuminated outer zones, and framed by the frosted, diffuse, shining edge. The fixture’s extremely simple design harmoniously matches other fixtures such as Doo-Wop.
27
The balance is in the dimensions Zirkon is available in three different sizes. This makes it easier to differentiate each room’s design expression. Large surface areas in a room seem more peaceful with a fixture of large diameter, and narrow corridors seem wider with a fixture of small diameter. Interesting ceiling environments can also be created using the various alternatives. Let the sizes help make a difference to the room environment.
