The vehicle headlight or lamp comprises a housing (6), a transparent cover plate closing the housing, a lighting element (1) arranged in the housing, and a cooling element (2) for the lighting element. The lighting element consists a LED and or a semiconductor chip or semiconductor-chip-array. The cooling element comprises a latent heat storage, which consists a phases change material (10). The phase change material is embedded into a chamber-like uptake (3) of the cooling element and is salt hydrates, paraffin, sugar alcohols, polyethylene and metal alloys. The vehicle headlight or lamp comprises a housing (6), a transparent cover plate closing the housing, a lighting element (1) arranged in the housing, and a cooling element (2) for the lighting element. The lighting element consists a LED and or a semiconductor chip or semiconductor-chip-array. The cooling element comprises a latent heat storage, which consists a phases change material (10). The phase change material is embedded into a chamber-like uptake (3) of the cooling element, is salt hydrates, paraffin, sugar alcohols, polyethylene and metal alloys and is penetrated in the uptake of a metal foam and metal grid. The areas of the web-like cooling element project into the chamber-like uptake. The melting- and solidification temperature of the phase change material lie between 50-180[deg]C. |
