ELECTRIC LAMP AND WIRE FOR USE IN THE ELECTRIC LAMP

摘要

The invention relates to an electric lamp (100), a wire (12), an image projection system (200) and a headlight (300). The wire (12) connects a first feedthrough (115) of a lamp at a far end of the lamp with respect to a lampholder (150). The wire is arranged between the lampholder and the feedthrough and is arranged along an outer wall of a vessel (105) of the lamp for electrically connecting the feedthrough to the lampholder. A first part (20) of the wire comprises a first conductive material which is connected to a second part (30) of the wire which comprises a second conductive material having a different heat tolerance compared to the first conductive material. The effect of the measures according to the invention is that by using different parts in the wire, the conductive material which can withstand high temperatures is applied only where needed. As a result, the efficiency of the lamps is improved.
