LEDs pack 1,700 lm, target projectors

The two high-power versions of the Ostar Projection LED for projectors feature a brightness of 1,700 lm. They offer a luminous flux from the available chip surface from 1,000 to 8,300 lm that can be produced, depending on the color and the version (two or four chip). An anti-reflection coated glass cover instead of the usual lens, together with external optics, ensures that the light is well bundled.

The two light emitting diodes contain a 2-mm² LED high-current chip based on state-of-the-art thin-film and UX:3 technologies. Both versions contain two (P1W) or four chips (P2W) with a total luminous area of 4 mm² and 8 mm² respectively. The P2W version emits light pulses with brightnesses of 1,000, 2,500 and 8,300 lumens for blue, red and green. These high brightness levels require current pulses of up to 32 A(8-A/chip) and optimized product design to efficiently remove the resulting heat. Volume production is due to start in March 2014.
