Abstract

An LED array surface-mounted on a circuit board and applied to a cooling member, such that any generated heat is optimally eliminated. The cooling member can be in any desired shape so that motor vehicle lights, such as blinkers, can be adapted to the outside contour of the vehicle. For a rotating light, the circuit board can be applied around a cooling member fashioned as a hollow cylindrical member which is adapted to rotate.
