LED packs 24 chips into tiny package, reduces the need for binning

摘要

With Cree's announcement of its XLamp MPL EasyWhite LED, the company moves another step forward in its quest to eliminate "binning" from the vocabulary of LED-lighting-application designers. The XLamp MPL EasyWhite can provide as much as 1500 lumens at 250 mA. This best-case number represents a pulsed rather than a constantly on drive current. With proper drive electronics and heat sinking, however, the LED can deliver equivalent light output to-and consume 78% less power than-that of a traditional 3000K, 75W BR-30 halogen light bulb.
