Abstract: A modular semiconductor light source assembly includes a semiconductor light source, such as a light emitting diode, which is mounted on a substrate which supplies electricity to the light source and which assists in removing waste heat therefrom. Substantially all of the light emitted by the LED is transferred to a lens by a light pipe, the cross section of the light pipe increasing from the light source to the lens and the lens having a general D-shape such that the light pattern formed by the lens is constrained in a first direction orthogonal to a second direction. The assembly can be combined with other similar assemblies or other light sources in a light fixture to produce a desired overall beam pattern such as a automobile headlamp low beam or high beam pattern.

Abstract: A light engine for use in systems such as automotive lighting systems employs two or more semiconductor light sources, such as LEDs. Light emitted from the light sources is captured by light pipes which are mounted such that the light capturing surface of the light pipes are properly positioned, with respect to the semiconductor light sources, substantially independent of changes in the dimensions of the light pipes which may result from thermal expansion or contraction of the light pipes. The light pipes transfer substantially all of the light captured from the semiconductor light sources to light emitting surfaces of the light pipes which can be appropriately located adjacent the output optics of the lighting system. The light engine can be easily assembled as the light pipes are retained in slots on a positioning member which is mounted at a known position with respect to the semiconductor light sources.

Activation of the drive rotates the plurality of shafts to selectively move the shield between an open position, in which the light rays project towards and reflect off of the high beam reflector surfaces to produce the high beam pattern, and a closed position, in which the light rays project towards and reflect off of the low beam reflector surfaces to produce the low beam pattern while the shield blocks a portion of the light rays from projecting towards the high beam reflector surfaces.

Abstract: An actuator is provided to selectively turn a diesel engine governor shutoff shaft to fuel "off" or fuel "on" position in response to keyswitch operation. An electric motor coupled through a gear train to a shutoff lever turns the lever to "on" or "off" position. A relay circuit controls the motor operation in response to keyswitch position and shutoff lever position. A feedback element moving with the shutoff lever mechanically interrupts the relay circuit by overriding the relay contact state to turn off the motor whenever the shutoff lever reaches an "on" or "off" position.
