LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has claimed another industry first with a record 276 lumen-per-watt white R&D power LED, exceeding its previous industry record of 254lm/W (announced last April).
Cree says that the record R&D result has been enabled by its SC3 Technology Platform (currently available commercially in its XLamp LEDs), which features advances in LED chip architecture and phosphor as well as a new package design.
Cree says that the LED efficacy was measured at 276lm/W at a correlated color temperature (CCT) of 4401K using a drive current of 350mA.
“The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption,” says co-founder & director of advanced optoelectronics John Edmond. “The innovation from our labs is the foundation for our lighting-class XLamp LEDs,” he adds. “Higher-performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs.”
