Light Emitting Diodes (LEDs) are increasingly being introduced into lighting market, and solid state lighting (SSL) is becoming a reality. But, this new technology still faces many challenges. Lighting consumes a huge amount of energy, currently 22% of all electricity consumed in the U.S. White LED sources are expected to be twice, or more, energy-efficient than fluorescent lamps. Thus, SSL is expected to have a big impact on nation's energy saving.
The Department of Energy (DOE) is promoting SSL with a goal of reducing the total energy spent by lighting to half by 2027, which will achieve a huge energy savings for the nation. We are working closely with DOE, especially in support of their Energy Star program, by developing national and international standards for LED/SSL, measurement services for LEDs, a laboratory accreditation program, and furthering research on all photometric aspects of solid-state lighting sources.
