Cree (Durham, NC) is announcing a new XLamp LED that can produce up to 160 lumens at 700mA, and has a typical output of 80 lm at 350mA. The company describes the XR-E series as a "new class of lighting LEDs,” with a luminous flux of up to 95 lm at 350mA, equivalent to a luminous efficacy of 85lm/W. At a 700mA current, the output is as high as 160 lm for the top bin.
Mark McClear, Cree's director of marketing for solid-state lighting, emphasized that LEDs that typically produce 80lm are already in volume production. Cree says that its new LEDs are designed to enable general-lighting applications, such as street lighting, retail high-bay lighting and parking-garage low-bay lighting, as well as to improve light quality in consumer applications such as flashlights.
The XR-E is the first power LED based on Cree's EZBright 1000 LED chip, unveiled last month. The device has a very low forward voltage, around 3.3V at 350mA, which contributed to lower power consumption. Color uniformity has improved with the implementation of a different phosphor process to deposit a thin, uniform layer of material directly onto the chip surface.
