ams OSRAM adds 0.33” DLP-compatible LEDs to OSTAR Projection Power range

ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has added four new LEDs to its family of OSTAR Projection Power products. The new LEDs are said to produce superior optical performance in projection equipment that is based on a 0.33” DLP (Digital Light Processing) imager.

Available now in production volume, the new OSTAR Projection Power LE xx P1MS/AS LEDs have a very close etendue match with the 0.33” DLP imager. The LEDs are available in Blue (LE B P1MS-EQET-23), Amber (LE A P1MS-RQRU-2), Deep Blue (LE D P1MS-ETFQ-R) and Converted Green (LE CG P1AS-TPTS-A) colors. When used in a typical four-channel configuration, these OSTAR Projection Power LEDs produce an output of 880lm on projector level. This is 5% brighter than the next best 0.33” DLP-compatible LEDs available from competitors, according to internal ams OSRAM tests.

The OSTAR Projection Power LE xx P1MS/AS LEDs are supplied in a compact package with a footprint of just 6.8mm x 7.6mm. The package has a copper metal-core PCB with isolated solder pad, making thermal system design easier and reducing the cost of thermal components.

The thermal performance of the OSTAR Projection Power LE xx P1MS/AS also supports very high current density and brightness – 6.6A/mm2 for the Blue, Deep Blue and Converted Green LEDs, and 4.5A/mm2 for Amber.

In multi-channel configurations, the LEDs support serial connection with a low forward current, enabling the use of a simpler, lower-cost LED driver.

“More vivid colors and sharper contrast in products such as home theatre projectors are now possible thanks to the high brightness of the latest OSTAR Projection Power LEDs and their excellent etendue match with 0.33” DLP imagers,” says senior marketing manager Tony Tam.

The new OSTAR Projection Power LE xx P1MS/AS LEDs are suitable for other applications in addition to projectors, including endoscopes, 3D scanners, and machine vision equipment.
