Cree has introduced a multichip MC-E LED with red, green, blue and white chips in a single package. It is also pairing new LED chip innovations with its XLamp XP-E package to deliver a high performance family of discrete, high-power color LEDs, Cree said.

The XLamp MC-E color is a package design, combining white, red, green and blue LED chips in a single component. This compact component provides design flexibility for 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% more flux than the existing XLamp XR color portfolio, with an 80%smaller footprint, Cree said. The XP color portfolio is available in flux bins, at 350 mA.

Compared to the current XLamp XR color LEDs, space between the LED die can be reduced by 75% with the new XLamp XP-E color LEDs and 94% with the new XLamp MC-E color LED, according to Cree. 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 the third quarter of 2009.
