the brightness in smartphone applications so embedded projectors with a system

The state-of-the-art lighting system, which is aimed at brightening the bridge and picking out its architectural features, had its first switch-on last night.Coloured bulbs, which vary in intensity, beamed from the central led high bay where giant Olympic Rings and the Paralympic Agitos, the swirling symbol of the Paralympics, will shine during the London 2012 Games.

An integrated miniature projector that can display images on a much larger surface than existing displays is the next giant leap for smartphones and cameras. This is known as embedded projection and uses LEDs as the light source. The greatest challenge so far for lighting technology has been the limited efficiency of the green light emitting diodes. This is because high brightness is essential if the projected image will be seen with ambient light. The Osram Ostar Projection Cube from Osram Opto Semiconductors is the perfect answer.

Efficient LEDs for red and blue light have been available for some time but LEDs that produce green with acceptable output have been rare. The new Osram Ostar Projection Cube from Osram Opto Semiconductors has now plugged this important gap. 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 LED high bay light 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.
