GE Lighting this week will illuminate a light-emitting diode replacement for the 100-watt incandescent light bulb — developed in its East Cleveland, Ohio, LED lab — that packages 27W of input power in a standard “A-19” bulb shape. The GE Energy Smart® 27W LED bulb incorporates proprietary synthetic jet technology that was enabled by GE’s collaboration with ecomaginationSM Challenge winner Nuventix, creator of LED cooling technologies for energy-efficient lighting.
GE’s 27W Energy Smart LED bulb, on store shelves in the U.S. and Canada the first half of 2013 (MSRP to be determined), will debut on a global stage starting May 9 at LIGHTFAIR International in Las Vegas, the world’s largest lighting trade show. GE’s existing portfolio of LED bulbs includes a 13W LED (60-watt incandescent replacement) and a 9W LED (40W incandescent replacement), which was the first incandescent-shaped (A-19) LED in the world to earn ENERGY STAR® qualification.
“Our innovation team has tackled a previously insurmountable technical challenge: cooling a 100W A-19 shaped replacement LED bulb without making it physically bigger,” says Steve Briggs, general manager of LED systems, GE Lighting. “Each subsystem such as optics, electronics and thermals needed to be designed for miniaturization and cooperative performance. We explored the limits of what’s possible and pushed far beyond industry expectations and competitors’ thinking and product offerings.”
New LED bulb performance metrics
GE testing confirms 100-watt incandescent replacement metrics: 1,600+ lumens, uniform omnidirectional light distribution, 3000K color temperature, 25,000-hour life rating (22.8 years at 3 hours per day), dimmable, no mercury, instant full brightness and 60+ lumens per watt—all fitting neatly in the standard A-19 bulb shape.
“Our achievement does more than backfill for the 100W incandescent bulb,” adds Briggs. “We now have a clear path to attaining even higher light levels, which will give customers more energy-efficient lighting options in both commercial and residential settings. This product fills a real customer need and further extends GE’s LED lighting leadership.”
LEDs are semiconductors that produce light. They must be cooled to ensure long life. In collaboration with GE, Nuventix developed a method for moving air to cool LEDs using an oscillating membrane, called a synthetic jet (an alternative to a fan), which fits within the envelope of the A-19 bulb shape.
“We expected our collaboration with GE Lighting would power some big advances in the application of lighting,” notes Jim Balthazar, CEO and president of Nuventix. “Once we came together last year, our teams wasted no time getting in the lab to build on the genius of GE’s LED bulb design, and to incorporate a synthetic jet solution that enabled GE to leapfrog its competitors. We’re a leader helping a leader, and it’s going to benefit consumers that want high quality LED lighting that performs as promised.”
