LED light sources are beginning to make inroads in some applications, now comprising 10% of the installed stock of MR16-style lamps, up from only 3% in 2010. Improved efficacy is expected to boost sales further, as LED products are expected to surpass efficacies of the most efficient conventional light sources within a few years, reaching levels greater than 200 lm/W within a decade. However, researchers see a challenge in the current use of lumen depreciation as a consumeror specifier-facing metric for estimated LED

to market in the fall. The shape of the lamp is built to maximize the impact of the unidirectional, yet diffuse, illumination created by its eight OLED panels, each just under 5 in. square. “You don’t need a shade, you can have a flat top,” he say, describing how OLED’s performance characteristics influenced his plans. “Instead of being a point source, it sends diffuse light in one direction.” Blackman chose Philips Lumileds’ Lumiblade panels as the OLED source, and the Aradess represents something of a partnership between the designer and the international lighting giant. “This is a signature product for them, plus a proof of concept to show how OLEDs perform.”•

Further, the lack of precision creates waste. Light is thrown away to protect occupants from glare with absorbing black panels, or lost in optics, inter-reflection and absorption of lenses, diffusers and reflective surfaces. Over a century, the accumulated waste from the losses within applied product design, spent lamps and energy used to make more heat than light is incalculable. To continue this paradigm is irresponsible. Enter the glass-shattering hammer of solidstate lighting. At less than one millimeter, LEDs produce the luminous potential of glass lamps in a tiny fraction of the space. These diminutive devices have already caused cracks in lighting’s glass prison, and shatter the ceiling of outright design potential. OLED, the rapidly emerging second wave in the solid-state prison break, smashes the relationship of lamp-diffuser by being both. For the first time in product design history, the

Integration of Control and Support Beyond form factor and light delivery, solid-state creates an opportunity to integrate leading-edge control and smart technology. Where glass bulbs powered by off-shelf ballasts have moved toward modest offering of dimmer control, solid-state products offer the opportunity to integrate controls interfacing, from Bluetooth to Wireless and conventional wired solutions.

Larger producers whose lines include both high and low volume items will benefit from broadening their inclusion of high performing solid-state products over more product offerings. Innovative newcomers will be afforded an opportunity to break new ground in lighting that address application barriers and qualitative walls set in glass. Most of all, scaled semi-custom short run solid-state production cannot be matched by glass product manufacturers, which ultimately can be used as an unfair advantage to end dependence on glass sources almost entirely.

Lighting would also need to meet the LEED Gold rating for sustainability and reduction of light pollution. The Solution: Lighting Design Collective created environments that combine natural light with white and soft pastel hues reminiscent of neighboring structures. Public spaces create daylight and sunlight effects so that the use of artificial lighting during the day was minimized. At sunset, lighting with color begins to dramatize the moods of the environments within the Galleria.

particularly commended for “…the implementation of a contemporary architectural lighting concept that achieves a unique atmosphere for the visitors and additional value to the shopping experience.” Burgas’ development goal is to achieve the status as one of the greenest cities in Bulgaria, and the project certainly helped fulfill that desire. Lighting for the galleria, for example, meets LEED Gold rating for sustainability and reduction of light pollution. The project was also cited as being built entirely with eco- and environmentally friendly building materials, delivered mainly from the region. The building has an envelope of high-insulation glass to reduce heat loads and a 38,000 sq. ft. green roof that increases the insulation qualities of the building. Deal Closer Rosenius reports positive feedback from users and mall management. “We are great believers in the emotional power of light and color. For Galleria Burgas, our objective was on the experiential quality of the space. These buildings are lifestyle merchandising environments.

PUBLIC TRANSIT IN TECHNICOLOR: MILLENDER STATION GETS A NEW IMAGE Detroit People Mover Detroit
The Detroit Transportation Company is testing a proposition that a combination of color and light will be a model to give the city’s 26-year-old People Mover a contemporary visual boost. It is testing its theory at the Millender Station stop, located in the Millender Center, a 33-story mixeduse residential, office center, and retail/hotel complex. With the new wall-to-ceiling design of pairs of LED tubes, the station’s light show is visible on the top floor of the five-level glassenclosed corner podium structure. The Detroit People Mover is an elevated, light rail system that serves a 2.9-mile, 13-station route in downtown Detroit. It opened in June, 1987 to provide convenient transportation for residents working and living in the center city district and for tourists. Comprised of two linked driverless trains, an automated system guides it on a single set of tracks along its route, stopping for passengers at predetermined platforms. It is one of five urban “people mover” systems built for U.S. cities. The other four are in Miami; Jacksonville; Irving, Texas; and Morgantown, W.Va. Overhead track systems operating in Seattle and Las Vegas are monorails that use more and larger passenger cars for their trains. Managers from the Detroit Transportation Corp., which owns and operates the People Mover, had observed the ridership holding at a rate well below planned capacity. They voted on a plan to enliven the station interiors, starting with an artistic lighting installation at the Millender Station. Light art for public transit has been gaining favor in recent years in urban areas.
ABOVE: The Detroit Transportation Corporation has initiated a program to boost ridership of its 26-year-old downtown People Mover system. For the glass-enclosed Millender Station, located within the mixed use Millender Building, its interior space has a new art-inspired LED lighting installation that communicates a lively, contemporary image.

DETROIT PEOPLE MOVER, Detroit
THE CHALLENGE: Comprised of two linked driverless trains, the Detroit People Mover is an automated system stopping for passengers at predetermined platforms. With ridership operating at well below planned capacity, the Detroit Transportation Co. (DTC) needed to boost awareness of the People Mover and integrate it into the city’s day-intoevening activities. THE SOLUTION: At the Millender Station stop, located in the Millender Center, a 33-story mixed-use complex, the station’s interior now glows with a new wallto-ceiling design of pairs of LED tubes, a light show that is visible on the top floor of the fivelevel glass-enclosed corner podium structure.

EDITORIAL PREVIEW: We span the globe taking a look at light as art and how SSL is helping make it happen. Three exhibits by pioneering light artist James Turrell, including a prominent one at the Guggenheim in New York (pictured at the right), are running simultaneously across the U.S. Halfway around the world, 800,000 people participated in the 18-day Vivid Sydney event in Australia. Look for more inspirational creations in the Topics at the Front feature. In the Market Setting Feature, Kevin Willmorth tackles the question of why wait?—at least when it comes to making the jump to adopting SSL. We’ll also take a look at the creative lighting of the new Intermix retail store in New York, where almost invisible LED sources help illuminate a major architectural component in this former meatpacking operation. Plus new products, news, and a look at mitigating flicker in AC-powered LEDs.
