Osram expands LED range across projection applications from 1W to 300W

LED maker Osram Opto Semiconductors GmbH of Regensburg, Germany has expanded its portfolio for the projection market with two new LEDs at the low and high ends of the performance range: OSTAR Compact (designed for small, efficient pico-projector systems in cell phones, PDAs and MP4 players) and OSTAR Power Projection (targeted at high-power projection applications such as home cinema systems with displays of 70 inches and more). Osram says that its LED portfolio now provides full coverage of the projection system range from 1W all the way up to 300W.

For small applications at the lower end of the performance range and available in red, blue, green and white, the OSTAR Compact measures just 3.9mm x 3.6mm and is a cost-effective component, particularly for pico projectors for small mobile devices. Manufacturers wanting very compact units can use a double-chip version that contains a red chip and a blue chip in one LED, saving space compared with the usual configuration of three individual LEDs (red, blue, green). As an SMT component, it can be easily integrated into standard manufacturing processes. Integrated ESD protection diodes guard against electrostatic effects.

Having low thermal resistance and operable at a current up to 36A, the OSTAR Power Projection LED delivers typical brightness values of 2700lm in red and 3500lm in green and an optical output of 13W in blue. While the dimensions of 45mm x 25mm seem large for a standard LED, the thermal resistance is only 0.77K/W. The LED suits all types of cooling (including water cooling). Since the junction temperature is the same for all colors (125°C), a uniform cooling system can therefore be used.

“LEDs will one day become the standard for all projection applications, including high-end applications,” believes Wolfgang Schnabel, marketing manager LED Projection. “We are well positioned for this swift migration of LEDs into projection applications and offer several OSTAR LED versions, namely Compact (up to 25W), SMT (10-40W), Projection (25-70W) and Power Projection (90-150W), to cover numerous applications – from cost-effective pico projectors to home cinema equipment as well as mobile projection systems for mid-range applications,” he adds.
