Cree gets 200 lm/W from XP package
The 200 lm/W LED has been dubbed XP-L, and delivers up to 1,226 lm at 350mA from its single die.
“XP-L LED enables an immediate performance increase of 50% or more as a drop-in upgrade for lighting designs based on XP-G LEDs,” said the firm.
This 200 lm/W LED follows hot on the heels of Lumileds’ 200 lm/W greenish Luxeon Lime LED announcement
Cree is aiming XP-L at high-intensity beam-forming applications where the small size allows them to be packed tightly together (0.5mm minimum spacing) to get more light from a given area compared with packing in the larger XM-L2s – the diameter of optics required to form a certain beam width is proportional to the diameter of the smallest circle that can be drawn around the emission area, so smaller emission diameter means more compact products.
Characterisation and binning is at 1050mA 85°C, and XP-Ls are available up to 90 CRI and ranging from 2,700 to 8,300K.
