摘要

The module has a reflector system (6) with a reflector, where a lamp (8) is accommodated in the reflector. The reflector system is formed with a light outlet (12) that is closed with a cover disk. The cover disk consists of glass-like material with small thermal coefficient of expansion. The reflector system consists of electrically conducting material and is provided with a reflective coating.
