The light (1) has a set of LEDs (15) arranged on a plate (9) in a closed housing that is made of a plastic. A cooling body (19) stands in connection with outside air and a heat dissipating unit dissipating heat from the plate to the body. Thermal coupling elements (17) formed from a firm well heat conducting material are built into a region of a housing wall (3) neighboring to the body and heat conductively connected with the plate and with the body, where the plate has a heat conducting metal core (13). The coupling elements and the body are made of copper, aluminum, brass and ceramics. |
