LIGHTING: LED lighting from the LIGHTFAIR International show
Next week in Las Vegas, the lighting industry will be gathering in for LIGHTFAIR International. LIGHTFAIR is one of the top lighting shows for architectural lighting, and this year efficiency, eco-friendly, and green lighting are on the most talked about list.
The announcements are starting to roll out about energy saving bulbs, and LEDs are the ones we are watching at GetWithGreen.com. Just today Renaissance Lighting announced their commercially available 4-inch solid-state LED downlight (Model: ED04). This LED recessed product offers more than 16 million color combinations without glare or visible LEDs.
As the newest arrival on the general illumination scene, solid-state LED lighting has yet to make a major market impact commensurate with its potential for outperforming and even replacing other types of lighting — until now. How does solid-state lighting differ from conventional lighting?
Incandescent lamps create light by heating a thin filament to a very high temperature. The reason for their low efficiency is that more than 90 percent of the energy consumed is emitted as invisible infrared light which creates heat. A fluorescent lamp produces ultraviolet light when electricity is passed through a mercury vapor, causing the phosphor coating inside the fluorescent tube to glow or fluoresce. There are efficiency losses in generating the ultraviolet light and in converting the ultraviolet light into visible light. Incandescent lamps typically have short lifetimes ? about 1,000 hours on average ? due to the high temperatures of the filaments. Fluorescents, including compact fluorescent lights, have lifecycles 10 times greater than incandescents, while LEDs can produce quality light anywhere from 50,000 to 70,000 hours.
The ED04 downlight’s compact package greatly expands its potential for use in all kinds of applications, and especially those where ceiling congestion tends to restrict the use of larger fixtures. The ED04 downlight adapts seamlessly to virtually any lighting scenario. Where smaller is better, the ED04 is easier to install from a weight standpoint, too, and it performs extremely well in wet locations or in outdoor under-canopy applications, according to CEO Barry Weinbaum.
“Utilizing green technology to make it environmentally friendly, our new ED04 outperforms the most popular 4-inch 50 par 20 products, yet uses only half the energy. It’s fully dimmable, and like all of our solid state products, is virtually maintenance free over the course of its 50,000-to-70,000-hour life span. Our customers will discover that Renaissance Lighting’s new pricing makes the decision to use our solid-state products an easier one, especially when considering the total cost of ownership,” Weinbaum said.
Renaissance Lighting’s unique downlight design begins with a circular array of LEDs at the perimeter of a patented integrating dome inside each fixture. The company’s unique optic design combines light uniformly before exiting the luminaire in glare-free fashion. The result is consistent color production and concealed sources that create smooth, uniform illumination patterns.
