Cree Inc. has expanded its high-power color LED product offerings with what it claims is the first multichip MC-E LED with red, green, blue and white chipsall in a single package.

It is also pairing new LED chips with its XLamp XP-E package. The XLamp MC-E color is a unique package design, combining white, red, green and blue LED chips in a single component. The products are aimed at color-changing LED applications that require high flux from a small lighting source, such as entertainment and architectural lighting.

The XLamp XP-E color LEDs provide up to 22 percent more flux than the existing XLamp XR color portfolio, with an 80 percent smaller footprint. The XP color portfolio is available in flux bins, at 350mA, up to Royal Blue: 500mW; Blue: 39.8 lumens; Green: 107 lumens; Amber: 56.8 lumens; and Red: 56.8 lumens.

Compared to the current XLamp XR color LEDs, space between the LED die can be reduced by 75 percent with the new XLamp XP-E color LEDs and 94 percent with the new XLamp MC-E color LED. This reduction in spacing can allow better color mixing and shadow reduction for color-based applications, including decorative, architectural and entertainment lighting.

Cree is sampling the MC-E and XP-E color LEDs, with production quantities targeted for Q3 09.
