Osram OSTAR Lighting source produces 1000 lumens

Osram Opto Semiconductors of Regensburg, Germany has developed its first cold white LED light source producing a luminous flux of more than 1000 lumens, using a new version of its OSTAR Lighting LED developed as part of the German government’s BMBF NanoLux program. This makes it brighter than a 50W halogen lamp, suitable for a wide range of applications in general lighting. Samples will be produced in the next three months. Market launch is planned for this summer.

The new LED is based on well-established components, enabling rapid progress from the development stage to the production stage, claims OSRAM. The huge increase in brightness is due to optimizing the overall chip, package and epitaxial process, the company adds.

The high-flux LED incorporates six closely packed 1mm2 high-power chips, giving high luminance. So a single OSTAR Lighting source with a 38° reflector can illuminate a desk with more than 500 lux from a height of 2m. Also, OSTAR produces light at a luminous efficiency of 75lm/W at an operating current of 350mA.
