Abstract: A traction battery assembly includes, among other things, a cover of a battery array, a holder attached to the cover, and a circuit board held by the holder in a position where the circuit board is spaced from the cover. The holder is configured to communicate thermal energy between the circuit board and the cover. A method of securing a circuit board of a traction battery pack includes, among other things, holding a circuit board with a holder, and attaching a holder that is holding the circuit board to a cover of a battery array. The circuit board held by the holder is held in a position where the circuit board is spaced from the cover.

Abstract: A lamp assembly having an area of heat concentration is provided with a conductive surface such as an aluminized coating or an insert that increases the emission of heat from the area of heat concentration. An absorptive surface is applied within the housing or on the bezel to increase thermal absorption at a location disposed above the area of heat concentration. Convective air flow within the lamp assembly is induced between the conductive surface to the absorptive surface. Methods disclosed include applying the conductive surface to the area of heat concentration and applying an absorptive surface coating within the lamp assembly.

Abstract: A lighting system for an automotive vehicle has a housing adapted for mounting to the vehicle with a generally outward facing backplate and at least one socket for an incandescent light source. A transparent lens cover is attached to the housing and forms an internal chamber between the lens cover and the housing. A staircase circulator on the housing comprises a plurality of steps and risers rising from the backplate toward the lens cover along a path that is spaced from the socket, wherein the path is generally along a natural convection flowpath of air within the chamber.

Abstract: A thermal filter is provided within a vehicle lamp assembly for reducing thermal radiation from reaching selected portions of the lamp assembly from an illumination light source disposed within the vehicle lamp. The thermal filter includes an inner envelope and an outer envelope in spaced relation to the inner envelope. The inner envelope and the outer envelope define a closed chamber therebetween. The closed chamber being disposed between the illumination light source and the selected portions of the lamp assembly. The inner envelope includes an interior portion. A thermal radiation absorbing agent disposed within the closed chamber. The thermal radiation absorbing agent receives radiation emitted from the illumination source. The thermal radiation absorbing agent is transparent to short wave visible radiation and is substantially opaque to long wave infrared radiation. A substantial portion of the long wave infrared radiation absorbed by the absorbing agent is retained within the closed chamber.
