Overcoming High Brightness LED Manufacturing Challenges

Overcoming High Brightness LED Manufacturing Challenges

On the 100th anniversary of Edison’s tungsten bulb, alternative lighting methods that use less energy and reduce pollution are gaining ground. Fluorescent (FL) or compact fluorescent (CFL) bulbs save energy but also have drawbacks such as unnatural color that may not be pleasing to the eye or in the case of CFL bulbs in particular, they may not fit in recessed lighting fixtures. And perhaps the most important issue, both FL and CFL bulbs contain mercury, requiring special handling for bulb disposal after use.On the horizon is a promising new technology, Light Emitting Diode (LED) devices that can provide a good replacement.

The L Prize

The United States Government's Department of Energy (DOE) is running a contest, named the L Prize, to reward the first organization to design and develop an energy efficient LED bulb. A recent article in the New York Times describes both the contest and the recent submission from lighting giant Philips. The prize for a replacement 60 watt bulb is $10 million dollars and for a replacement reflector flood lamp it's $5 million dollars.
