LED lighting devices with high extraction efficiencies

Abstract:

A lighting device for a vehicle. The lighting device includes an LED having a central axis. light distribution of light emitted by the LED is substantially symmetric about the central axis. The lighting device also includes a reflector for reflecting at least a portion of the emitted light. The reflector is positioned relative to the LED such that a combined light distribution of the emitted light and reflected light is not symmetric about the central axis and a maximum light intensity direction of the combined light distribution of the emitted light and the reflected light is angled with respect to the central axis. The position of the reflector relative to the light-emitting semiconductor device is adjustable such that an adjustment to the position of the reflector changes a direction of the maximum light intensity direction of the combined light distribution.
