New ams OSRAM OSTAR LEDs

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 colours. When used in a typical four-channel configuration, these OSTAR Projection Power LEDs produce an output of 880 lm on the 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 6.8 x 7.6 mm. The package has a copper metal-core PCB with an 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/mm2 for the Blue, Deep Blue and Converted Green LEDs, and 4.5 A/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.

Tony Tam, Senior Marketing Manager of ams OSRAM, said: ‘More vivid colours 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.’

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.
