AMS OSRAM OSTAR LEDs boost mini DLP projectors’ color, contrast, and brightness

ams OSRAM adds four new LEDs to its family of  OSTAR Projection Power products. The new LEDs produce superior optical performance in  projection equipment that is based on a 0.33“ DLP (Digital Light Processing) imager. 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, Amber, Deep Blue and Converted Green  colors. When used in a typical four-channel configuration, these OSTAR Projection Power LEDs  produce an output of 880 lm on projector level. This is five percent 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 6.8 mm x 7.6 mm. 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 excellent thermal performance of the OSTAR Projection Power LE xx P1MS/AS also supports  very high current density and brightness – 6.6 A/mm²for the Blue, Deep Blue and Converted Green  LEDs, and 4.5 A/mm²for 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. 

Tony Tam, Senior Marketing Manager of ams OSRAM, said: ‘More vivid colors and sharper contrast  in products such as home theater 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.’ The new OSTAR Projection Power LE xx P1MS/AS LEDs are ideal for other applications in  addition to projectors. These include endoscopes, 3D scanners, and machine vision equipment. The OSTAR Projection Power LE xx P1MS/AS LEDs are available now in production volume.
