Headlamp LED Delivers Clearly-Defined Beam

Employing an integral shutter, the OSTAR headlamp LED promises to simplify automotive headlamp optical systems by emitting a highly efficient and clearly defined light beam without the need for external shutters. The LED is available in one-, two-, three-, four-, or five-chip arrays, allowing designers to create different illumination patterns for virtually any headlamp design. A glass cover bonded to the frame protects the chips and helps prevent scatter losses. With a 12W rating, the headlamp produces between 125 lumens at 700 mA (one chip) and 1,000 lumens at 1A (five chips). Additionally, with a street-legal color temperature of 6,000 Kelvin, the LEDs emit light nearly identical to natural daylight and the headlamp specifies a lifespan of 10,000 to 20,000 hours.
