Beam shutter in LED package |
摘要 |
A beam shutter is disclosed that is affixed to an LED die submount or circuit board to sharply define the emitted pattern. The beam shutter may be a solid piece of aluminum or any other opaque material to block a portion of the light emitted from the LED die. The beam shutter is particularly advantageous for shaping the LED light for car headlamps.
