Cree announces XLamp® performance breakthrough with their new XP-E colour LEDs

Cree has expanded its industry-leading XLamp® XP-E range to include the highest performance family of discrete, high-power colour LEDs available.

With the industry’s highest performance, the XLamp XP-E colour LEDs provide up to 22 percent more flux than the existing XLamp XR colour portfolio, with an 80 percent smaller footprint. The XP colour portfolio is available in flux bins, at 350 mA, up to:

Royal Blue: 500 mW
Blue: 39.8 lumens
Green: 107 lumens
Amber: 56.8 lumens
Red-Orange: 62.0 lumens
Red: 56.8 lumens

Compared to the current XLamp XR colour LEDs, space between the LED die can be reduced by 75 percent with the new XLamp XP-E colour LEDs. This reduction in spacing can allow better colour mixing and shadow reduction for colour-based applications, including decorative, architectural and entertainment lighting. Samples of the XP-E colour LEDs are available from Anglia, with production quantities targeted for Q3 calendar 2009.

"We have leveraged the LED chip and packaging innovations developed for our lighting-class white LEDs to deliver real performance gains in high-power colour LED applications," said Paul Thieken, Cree marketing director, LED components. "The combination of technology innovation and package flexibility gives designers working with Cree’s colour LEDs increased brightness, flexibility and control."
