Researchers from Osram Opto Semiconductors have developed an LED chip that makes it possible to offer smaller pocket projectors, vehicle headlights, and cell phone camera flashes. In combination with a new package the new UX:3 chip is 50 percent brighter than the precursor package. In combination with an optimized lens, the light is much better distributed. The chip is used in the Oslux LED, which is therefore considerably more efficient at high currents than previous LEDs and is impressive for its very high luminous efficiency over a small area.
