Cree launches color LEDs with double the lumens-per-dollar performance

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has announced the commercial availability of XLamp XB-D color LEDs and XLamp XM-L multi-color LEDs, providing lighting manufacturers with discrete and multi-color LED options to more cost-effectively address a wider spectrum of applications such as architectural, vehicle and display lighting.

XLamp XB-D color LEDs extend the double lumens-per-dollar performance of the XB package to color LEDs, delivering up to 40% higher maximum light output than XP-E color LEDs. Cree says that the combination of performance and the small size of XB-D color LEDs enables better color mixing and lower system cost through fewer LEDs. Now available in color as well as existing white color temperatures ranging from 2700K to 6200K, users can support a full range of color in the single XB footprint.

XLamp XM-L color LEDs are claimed to be the brightest and smallest multi-colored LED of their power class, delivering red, green, royal blue and white in one LED at twice the lumens-per-dollar of the MC-E color LED. The XM-L color LED is 60% smaller than the MC-E LED, reducing the distance between LED die, to create a small optical source for what is claimed to be excellent optical control, efficient color mixing and simplified design. “The smaller and brighter XM-L color LED allows us to improve system performance and lower system cost,” comments Michael Johnson, VP of engineering at LED lighting fixture designer and manufacturer The Black Tank Inc of Amesbury, MA, USA. 

XLamp XB-D color LEDs deliver output of up to 1416mW for royal blue, 92 lumens for blue, 198 lumens for green, 210 lumens for red and 261 lumens for red-orange, all at a drive current of 1A in the 2.45mm x 2.45mm footprint.

XLamp XM-L color LEDs deliver up to 89 lumens for royal blue, 214 lumens for green, 229 lumens for red and 272 lumens for white at 1A in the 5mm x 5mm footprint.

Cree XLamp XB-D and XM-L color LED samples are available now, and production quantities are available with standard lead times.
