Specialist in LED lighting solutions, Cree has reported a record-breaking luminous efficacy of 231 lm/W for a white power LED. This is an important breakthrough and shows Cree’s continuous efforts in advancing the LED lighting solutions.
According to Cree, a single die part at 4500 K of correlated color temperature was used to measure the LED efficiency at 231 lm/W. Results were achieved by conducting 350 mA testing at normal room temperature.
Cree’s latest research and development result has sophisticated features of the technology utilized in Cree XLamp white LEDs. The company expects that its ultra-performance LEDs would pave way to new LED-based uses and reduce the expenditures of existing LED-based designs.
According to John Edmond, who is the Co-Founder of Cree and Director of Advanced Optoelectronics, some years ago, 200 lm/W was believed as the optimum luminous efficacy possible for a lighting-class LED. The company surpassed that limit in 2010 and now has attained 231 lm/W. The advancement from Cree’s laboratories is the basis for its groundbreaking XLamp LED portfolio and demonstrates its expertise in the LED lighting solutions, he added.
