A new line of high-performance LEDs have been developed that will make it possible for users to build mini-projectors.

Introduced by Osram, an LED lighting specialist and subsidiary of electronics firm Siemens, the energy-saving bulbs are the key components in the new device - which can be carried around and connected to mobile phones, laptops or cameras.

The LEDs also produce a glow strong enough to project images measuring more than one metre in diagonal on a wall. Measuring

Due to the energy efficient qualities of LED lighting, the projectors can be operated using very little electricity and can run on batteries.

"In the case of the 3M device, their optical performance is sufficient to produce images with a diagonal of up to 127 centimetres, depending on the lighting conditions," Siemens commented.

In related news, Osram recently declared its venture into street lighting, claiming its LED lighting module uses significantly less energy than conventional street lamps
