OSRAM develops maximum 3.6W high power infrared LED

Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors GmbH) in July 11, 2007 to 13, held in Chiba County Makuhari Messe Convention Center "Inter" Opto 07 ", exhibited by a single package can output 3.6W infrared LED" OSTAR Observation "," SFH 4730 "and" 4740 SFH "two. Input 1A current output power, SFH 4730 is 3.0W, SFH 4740 is 3.6W. Supply samples will be available from August 2007.

Infrared LED "SFH 4740" for 3.6W optical output power"

SFH 4730 and SFH 4740 through the connection of the company's original product "SFH 4230" 1.0mm * 1.0mm infrared LED chip, obtained a high output power of. Thermal resistance are 2.8K / W, significantly less than the original product 15K / W. The ceramic material is adopted to improve the heat dissipation. Infrared LED chip packaging surface of the frame, SFH 4730 and SFH 4740 different, SFH black material used to suppress the reflection of infrared light. Therefore, the utility model can be combined with a condensing lens. The SFH 4740 is the use of white materials, packaging surface is easy to produce light reflection, but it can get higher than SFH 4730, up to 3.6W light output power.

Package size is 33.0mm * 13.5mm * 4.6mm. Power consumption is 24W. The luminous wavelength is 850nm.

The company's goal is to apply the new LED to the infrared light source of the car's infrared night vision system. In addition, the utility model can be used for industrial purposes and is used as the light source of the monitoring system and the safety system.
