Osram LEDS used in micro projectors

LEDs
3M is including Osram Opto Semiconductors' LEDs in its micro projectors, which can be connected to mobile phones and cameras.
The small, bright, energy-saving diodes are the key to developing micro projectors, which could not be implemented with other light sources.
They make screen sizes of more than a metre possible.
Using 3M's small MPro120 Pocketprojector, which is about the size of a mobile phone, users can project videos or photos onto a wall.
Depending on lighting conditions, the LEDs project images of more than a metre.
The MPro120 can also be connected to other devices with an AV input, such as digital cameras or laptops.
By coordinating 3M's Light Engine with Osram Opto Semiconductors' LED, the projector provides efficiency of more than ten lumens per watt.
As it works with a multichip LED, which comprises two green chips plus a red and blue one each, the unit achieves good colour rendering.
