The Ostar Projection Cube from Osram Opto Semiconductors, a new green LED component designed for smartphones and cameras, doubles the system brightness for embedded projection.. At 110 lumen per watt (lm/W), it is much more efficient than all other previously available green LEDs in the embedded projection sector.
 
For the first time, the Osram Ostar Projection Cube enables high output to be achieved in embedded projectors. "The new LED almost doubles the brightness in smartphone applications so embedded projectors with a system brightness of up to 25 lumen are possible", said Wolfgang Schnabel, Marketing Manager Projection at Osram Opto Semiconductors. This means that the image is clearly visible even with ambient light and, thanks to the efficiency of LED technology, the projector can also be used in mobile applications with limited battery capacity.
 
The new green LED is available in two versions – with a 1 mm edge length chip and with a 0.75 mm edge length. The Osram Ostar Projection Cube is therefore suitable for all standard imager formats in mobile terminals. The two LED versions are also very bright. Depending on the size of the chip, they produce 260 lm at 700 mA and 2.3 W or 130 lm at 350 mA and 1.2 W.
 
Francis Nguyen from Osram Opto Semiconductors will present this new LED at the Projection Summit 2012 in Las Vegas during his talk on the "Evolution of LEDs used in Picoprojectors"
