GE integrates LED thermal management for 100W bulb within A-19 form factor

May 9, 2012 – BUSINESS WIRE — GE Lighting (NYSE: GE) is introducing a 100W-equivalent light-emitting diode (LED) bulb, developed in East Cleveland, OH LED lab with Nuventix, LED cooling technology developer and the winner of GE’s ecomagination Challenge. GE invested in Nuventix, and licensed its patent portfolio, in 2011.

GE’s 27-watt Energy Smart LED bulb is in a standard “A-19” bulb shape, with 1600 lumens (60 lumens/watt), uniform omnidirectional light distribution, 3000K color temperature, and 25,000-hour life rating (22.8 years at 3 hours per day).

The bulb is manufactured with a proprietary synthetic jet technology enabled by Nuventix’ collaboration. Nuventix’ oscillating membrane, called a synthetic jet (an alternative to a fan), cools the LED chips and fits within the form factor of the A-19 bulb shape. Each subsystem — optics, electronics, thermals — must be “designed for miniaturization and cooperative performance,” says Steve Briggs, general manager of LED systems, GE Lighting. This technology provides a “clear path” to higher light levels and more energy efficiency.

The bulb will be in stores in 2013, and is debuting at LIGHTFAIR International in Las Vegas this week. GE’s existing portfolio of LED bulbs includes a 13-watt LED (60-watt incandescent replacement) and a 9-watt LED (40-watt incandescent replacement), as well as others in various shapes, wattages, and colors.
