Worcester, MA ¨C February 29, 2008 ¡ª Allegro® announces a new series of RGB multi chip LEDs that provide a range of high-powered ALGaInP red, and InGaN green and blue LEDs that can be used in general lighting applications, amusement and gaming equipment, and for backlighting TFT displays. Each module combines eight LEDs in four or eight separate channels.

Modular design allows the SEPM devices to be easily ass embled into string arrays by simply connecting the modules in series. The devices also provide superior color balance throughout the display because of the high density of LEDs that can be achieved. This also minimizes the distance that power and control lines must run between LED modules and from the LED modules to the control electronics.

The white resin compound is especially formulated for superior reflectance and transmittance of the generated light. Enhanced thermal dissipation is achieved through the incorporated heatsink on the bottom of the package. The heatsink can be mated directly to an external radiator through the PCB for superior heat conduction allowing dense placement of modules.

The leadframe is plated with silver, providing a highly-reflective surface for the bottom and sides of the emitting area. The terminals and heatsink are also silver-plated.
