200 lumen per watt barrier breaks by Cree
A new R&D record for a white high-power LED announced by Cree.,ltd and claims to have set a new laboratory record for a white, high-power LED of 208 lm/W. Just two months ago, Cree reported an R&D result of 186 lm/W.
The 208 lm/W LED produced 208 lumens of light output at a with color temperature of 4579 K. The tests were conducted under standard LED test conditions at a drive current of 350 mA at room temperature. Which will saving a lot of energy in the mean time.
“We have made effect and now broken the elusive 200-lumen-per-watt efficacy barrier for a single white power LED,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “This is a result of improvements in blue optical output power, lower operating voltage and higher conversion efficiency. We continue to push the envelope in white LED technology to enable the highest efficiency white lighting products in the marketplace.”
However, this level of performance is not yet available in Cree’s production LEDs. The company says that this R&D result passes a significant milestone within the solid-state lighting industry, as well as demonstrating Cree’s relentless drive to increase the performance of its LEDs.
“This is a good result that improve the efficency of the bluelight, contains optical output power, lower operating voltage and higher conversion efficiency. We continue to push the envelope in white LED technology to enable the highest efficiency white lighting products in the marketplace.”
