Abstract
A semiconductor light module comprising: integrated drive electronics, a semiconductor light source applied to a disk-shaped module, the surface of which is electrically conductive, and wherein the module has good thermal conductivity. The drive electronics are positioned around the semiconductor light source, and the drive electronics comprise a circuit board having at least first and second conductor track levels. The first track level is oriented outward in the light emission direction in the installed state, and the second track level is enclosed by a closed cavity incorporated into the module. Ground-carrying lines of the circuit board are electrically connected to the surface of the module.
