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: 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: A lamp system having a housing, wall portions defining a cavity and an opening. A light source, generally an LED, is located within the cavity and at least one thermoelectric device is disposed in one of the wall portions. The thermoelectric device has a first side oriented towards the cavity and the second side oriented away from the cavity. When in operation, the thermoelectric device will transfer heat from inside the cavity, via the first side of the thermoelectric device, to the second side of the thermoelectric device.

Abstract: A lamp for emanating light includes a light source and a lens having an axis. The lens has a radially outward light entering surface to introduce light from the light source into the lens in the form of an intra-lens beam. The light entering surface is at a radially outward edge of the lens. The lens also has an axially outward light exiting surface and a lens back surface, which has reflective stepped faces spaced apart by connecting faces. The reflective stepped faces are arranged at an angle to the lens axis to intercept the intra-lens beam and reflect a reflected beam through the axially outward light exiting surface.
