Powerful light for slimline displays

High-power Ceramos Reflector LED

(PresseBox) ( Regensburg, )
All the properties that light sources need for backlighting medium-sized LCDs (5 to 20") are combined in OSRAM's new high-power Ceramos Reflector LED in its tiny package. Developed for injecting light into a light guide, it offers high brightness and impressive efficiency. The LED also withstands temperatures as high as 150°C and is extremely durable with a life of up to 50,000 hours.

Thanks to ThinGaN technology, the Ceramos Reflector provides strong light, coupled with high luminous efficacy of 70 lm/W from an operating current of 80 mA. Its small ceramic package measures just 2.3 x 3.2 x 0.8 mm and is thermally stable, allowing high packing densities. An oval out-coupling window enables light to be injected into thin light guides only 2 mm high. This is in keeping with the latest trend for slimmer and slimmer displays with high luminance. Applications include satellite navigation devices for road vehicles and aircraft and any other displays that need to be read in bright ambient light.

These high-power LEDs are resistant to shocks and vibrations and are suitable for standard solder processes. They do not use any mercury at all and meet the requirements of the RoHS directive. "More and more display manufacturers are looking for an eco-friendly alternative to cold cathode fluorescence lamps", said Winfried Schwedler, Marketing Manager for LCD Backlighting at OSRAM Opto Semiconductors. "With our high-power LEDs such as the Ceramos, we offer ultra-bright and efficient light sources that also save energy."

The high-power Ceramos Reflector LED is housed in a thermally stable mini ceramic package that allows for high packing densities.
