The new OSTAR Projection SMT LED from OSRAM Opto Semiconductors , which launched June 10, is more compact and efficient than ever before and is designed for integration into ultra-miniature pico projection applications where space is at a premium. This compact LED module measures just 5.8 x 4.7 x 1.5 mm and, in contrast to its predecessor, does not require additional connectors on board for electrical interface. Thanks to SMT (surface mount technology), this new version of the OSTAR Projection LED is now suitable for standard soldering processes, according to a recent report by the Society for Information Display.

The OSTAR Projection SMT LED is ideal for applications such as the pico projectors now being integrated into cell phone and other mobile appliances. Pico projectors can be either integrated directly into the phone housing or attached to the phone as an accessory.

An embedded cell phone pico projector typically measures 1.5 cm x 3.0 cm; in this configuration, the OSTAR Projection SMT LED provides a system brightness of 10 screen lumens (lm) with a power consumption of 1 W. The larger accessory versions of pico projectors, which measure 7.5 cm x 7.5 cm, can be operated with a higher wattage and can achieve brightness values of more than 15 lm.
