Abstract: A condenser lens and a headlamp assembly employing the condenser lens improves control over the beam spread characteristics, while at the same time reduces the package size of the headlamp assembly. The condenser lens is provided for a projector-type headlamp assembly having a light source emitting light which is projected longitudinally downstream in front of a motor vehicle. The condenser lens generally includes a main body of light transmitting material. The main body defines a first surface receiving light from the light source and a second surface emitting the light. The second surface has at least one facet structured to spread the light and provide a predetermined beam pattern.

Abstract: A LED package having an LED chip and a thermoelectric device. The thermoelectric device a has a first side in thermal communication with the LED chip and a second side in thermal communication with a heat sink to create a thermal gradient between the LED chip and the heat sink. The thermoelectric device is coupled in electrical series with the LED chip and powered such that a current provided the thermoelectric device is proportional to a drive current of the LED chip.

Abstract: A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.

Abstract: An automotive light assembly produces numerous beam patterns meeting automotive requirements through the reduction of light scatter and collection and redirection in efficiencies. A light source projects light laterally, which is collected by a light conducting body having a hub and a plurality of fingers extending from the hub. By using a plurality of small individual fingers, large and bulky light pipes are eliminated and the light collection and redirection efficiency is improved.

Abstract: A light emitting diode device capable of shielding or filtering the light in a manner to provide high-gradient edges or regions within the beam pattern. The LED device is also capable of providing selective coloring, thereby cost effectively improving the adaptability and number of applications which can utilize the LED device. The LED device includes an optical layer is positioned in front of a LED chip that includes a material having light transmission properties which change in response to electricity being supplied to the optical layer. The optical layer can thus transmit or absorb light from the LED chip, thus shielding or filtering light from the LED chip.

Abstract: A near field lens for an automotive light assembly which has a reduced thickness. Generally, the near field lens includes a main body of light transmitting material. A pocket is formed in the main body for receiving light from a light source. The pocket is defined by an inner radially facing surface and an inner axially facing surface. The inner radially facing surface is structured to reduce the thickness of the lens.

Abstract: A near field lens is for an automotive light assembly, generally comprising a central body positioned between opposing side bodies. The central body extends in a vertical direction, while the side bodies are positioned on horizontal sides of the central body. The opposing side bodies are structured to collimate the light both horizontally and vertically, while the central light body is structured to collimate the light vertically but not substantially collimate the light horizontally.

Abstract: A headlamp assembly for a motor vehicle is disclosed as having a light source, a chamber within which the light source is located, and a cooling channel extending through the chamber. The chamber substantially fluidly sealed from the atmosphere and the cooling channel is fluidly sealed from the chamber to prevent direct fluid exchange between the chamber and the channel. Heat exchange, however, is permitted between the chamber and the cooling channel. The heat exchange may be further promoted by a plurality of heat exchange fins extending away from the wall of the cooling channel.

Abstract: The present invention is an automotive lighting system including semiconductor laser sources, optical waveguides, and focusing assemblies for generating, transmitting, and directing light for a variety of automotive applications. In particular, the present invention includes phosphor-based semiconductor lasers integrated into an automotive lighting system that is usable for producing white light in close proximity to a focusing assembly, or remotely from the focusing assembly through a network of optical waveguides in a distributive lighting system.
