GE Higher Efficiency LED Lights use Jet Engine Technology
Jet-cooled GE LED lights use 1/3 of the energy of comparable 100 watt halogen bulb
GE is expanding its line of energy-efficient lighting, this time employing jet engine technology to make its LED lights more efficient. GE developed the new LED lights in conjunction with the University of Maryland with money from a two-year federal grant. U.S. legislation regarding energy efficiency requirements for lighting will make incandescent lights obsolete in 2012, so companies like GE are increasingly investigating and developing more energy-efficient forms of lighting, including LED lights.
GE's new LED light bulb emits 1,500 lumens, which is about the same amount of light as a 100-watt halogen spotlight, while using only one-third as much energy. GE has accomplished this by using "dual cool" jets, which are tiny bellows that facilitate the flow of heat away from the light source by creating air currents. GE is highly experienced with this technology as they have been employing it in their wind turbines and jet engines. Keeping the LED lights cool allows GE to increase the current on the LEDs, producing more light with fewer LED chips.
While GE currently only makes LED spotlights and floodlights, the company expects to release its first household LED light in November. That light will consume only 9 watts of energy and will be comparable to a 40-watt incandescent bulb. Next year, GE plans to roll out a 60-watt dimmable LED light bulb, and by 2013, GE expects that 15% of its lighting sales revenue will come from LED lights.
