Illumination device for motor vehicle, comprises carrier flowing through cooling medium circulating through cycle that is in heat conducting connection with light emitting diode, where carrier is implemented as flat pipe

摘要

The illumination device (1) comprises a carrier (6) flowing through a cooling medium circulating through a cycle (8). The carrier is in heat conducting connection with a light emitting diode (4). The carrier is implemented as a flat pipe. The carrier has multiple guiding units in the inner side, where a flow path for the cooling agent is defined over the guiding units. The cooling agent promoting pump (9) is switched into the cycle.
