LED Backlighting

Osram Opto Semiconductors (Santa Clara, CA) is introducing the Ceramos™ Reflector LED for backlighting mid-size (5-20-in.) LCDs. Specifically designed for light guide-based backlighting of displays in high, ambient-light conditions, such as those found in TFT displays, automotive dashboards and aircraft cockpits, the slim profile of the Ceramos is suitable for in-coupling into light guides as thin as 2mm. This feature also makes the LED ideal for edge lighting for LCD TVs and monitors.

The Ceramos reflector LED is powered by OSRAM's patented ThinGaN® LED technology, which enables it to operate at 70 lumens per watt at 80mA. The company reports a 50,000-hour lifetime, and its SMD ceramic package enables excellent performance at high operating temperatures up to 302 degrees F, and is compatible with standard, surface-mount processes.

The slim (2.3 x 3.2 x 0.8mm), compact package dimensions facilitate integration into small display designs, and the oval out-coupling window allows for use in thinner light guides. The product is mercury-free and RoHS-compliant.

In addition to display backlighting, the reflector LED can be used for camera flash and strobe lighting; reading lamps in aircraft, cars and buses; decorative and entertainment lighting; and signage or marker lights.
