Architectural SSL - July 2013

AT THE FRONT Healthcare—LED is gaining ground in the market not only because of energy savings—or even color—but for its compatibility with medical equipment.

SSL BUZZ DOE’s Multi-Year Plan notes LED experienced a 25% growth world wide in 2012—a rate expected to continue for the next few years.

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

OLEDS: COMING TO MARKET

Fixture Designer Turns to OLED Lighting designer Steven Blackman has spent 30 years developing fixtures to work with every lighting technology on the market. Now, he’s setting his sights on OLEDs, with a new fixture, the Aradess, and a new company, Blackjack Lighting— both informed by his interest in following the next big thing. “I started in the lighting industry when halide was the new technology,” he says, noting the ways new illumination equipment can feed into the design of fixtures, themselves.

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.”•

In its “off” state, the product looks like a piece of wall art, with the fabric panels themselves available in white or a specific color. But when turned “on,” the multicolored LEDs integrated into the frame are able to play low-resolution video on the fabric itself.

Philips sees the product, described as a “mood wall,” as a perfect fit in waiting rooms or MRI rooms—anywhere there’s a degree of anxiety.

But, as noted, its end use is really in the hands of the individual designer.

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.

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. When product designers look upon solid-state as their preferred source founded on the freedom to delight customers most effectively, they will break the remaining glass walls down getting to it.•

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.

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.

New York’s Metropolitan Transit Authority incorporated light art for two of its most recently renovated stations, at 96th St. and Broadway and at Columbus Circle. The Pershing Square station

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.

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.
