Abstract: An automotive lighting system employing semiconductor light sources includes LED light sources (52) which are mounted to an edge of a heat pipe (44) such that emitted light from the LED light sources travels toward a reflector (32) at the back of the housing (24) of the system, where it is reflected and/or focused forward through the lens (40) of the system. The heat pipe is thermally connected to a heat sink (35) which extends outside of the housing and which operates to remove heat from the LED light sources. The thickness of the heat pipe is significantly less than the size of the reflector, so that only a small amount of reflected light from the LED light sources is obscured.

Abstract: A headlamp comprising at least one array of illumination light sources, the light sources positioned substantially corresponding to a desired illumination beam pattern for the headlight, the light from the light source of the array being provided to a lens which projects the light in the illumination beam pattern. Preferably, the light is provided from LED light sources which are coupled to fiber optic cables to form the array of illumination source. Also preferably, the light sources can be illuminated in different patterns, to provide different illumination beam patterns.

Abstract: The headlamp system of the present invention includes a source array of semiconductor light sources and a lens system to produce a first component, such as spread light, of desired beam patterns and a source array of semiconductor light sources and a lens system to produce a second component, such as the hot spot components, of the desired beam patterns. Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of light pipes which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.

The valve is operably engageable by a regulator constructed to allow flow of the gas therethrough.

Abstract: A light engine to provide light from a plurality of semiconductor light sources in an automotive lighting system, such as a headlamp, includes at least two substrates each of which has semiconductor light sources mounted thereon. The semiconductor light sources are spaced from one another on the substrates for cooling purposes.

The light engine further includes at least one transfer device comprising a bundle of light pipes, one light pipe for each semiconductor light source, and each light pipe has a receiving end which is located adjacent a respect one semiconductor light source and an emitter end which is located in close proximity to the emitter end of each other light pipe emitter end.

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.

Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of fiber optic cables which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.

Abstract: A headlamp assembly for producing high and low beam patterns includes a housing having a reflector. The reflector includes high and low beam reflector surfaces. A light source is disposed within the housing for producing light rays projecting towards the high and low beam reflector surfaces. A plurality of shafts extends alongside the light source. A drive is operatively connected to the plurality of shafts for rotation thereof. A shield is connected to the plurality of shafts. 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: License management systems and methods allow licenses for a computer program to be available for use at each of a plurality of nodes of a network. If a valid license file at a local node contains an unexpired, available license, a license manager at the local node permits the computer program to be executed at the requesting local node. If no such license is available in a valid license file at such local node, the license manager searches the other nodes for a valid license file containing an unexpired, available license. In one embodiment, if an unexpired available license is located in a valid license file at a second (or "remote") node, the license manager transfers such license to the local node, and assigns and encrypts a unique identification to such transferred license. The original record of the transferred license is modified by erasing it from the license file at the remote node so that the transferred license is no longer available there.

A passageway interconnects a lower inlet and upper outlet openings. A gravity actuated displaceable valve element is mounted for guided movement in the passageway. A valve element seat is provided internally of the valve body about the inlet opening for receiving the valve element in close seated contact thereon. A stop element is provided internally of the body adjacent the outlet opening to limit the displacement of the valve element while permitting fluid passage from the inlet opening to the outlet opening about the valve element.
