Abstract

After the revolutionary invention of the blue LED in the 1990s, LEDs have been rapidly proliferating as new energy-efficient light sources. White LEDs currently reach more than 300 lm/W experimentally. Since 18% of the total site electricity use in the U.S, replacing light bulbs and fluorescent tubes with LEDs has a potential to save 217 terawatt-hours (TWh… (More)
