Headlamp LED Delivers Brighter Light

With its integrated shutter, the OSTAR headlamp LED from OSRAM Opto Semiconductors will simplify automotive headlamp optical systems by emitting an efficient and clearly defined light beam without the need for external shutters that are common in current headlamp designs. The high-powered LED is available in one-, two-, three-, four- or five-chip arrays, providing the flexibility to create different illumination patterns for virtually any headlamp design. A glass cover that is bonded to the frame protects the chips and helps prevent scatter losses. This headlamp LED produces between 125 lm at 700 mA (one chip) and 1,000 lm at 1 A (five chips). Improvements to the chips, converter and overall package design result in a brighter light while maintaining a 12-W power rating.
