White, single-die LED is brightest new star

摘要

Fulfilling a promise made in the laboratory three years ago, the XLamp XM-L2 LED delivers efficiencies up to 186 lm/W (at 1W, 25℃, 5,000K) - the highest of any single-die LED commercially available today. Driven at 10 W, a single LED can deliver a lumen output equivalent to a 75-W incandescent bulb. Built with SC~3 silicon-carbide technology, the LED doubles the lm/$ figure, delivering 20% more lm/W than the previous generation. Thus lighting manufacturers can use fewer LEDs to deliver better lighting systems at a lower cost.
