Abstract

A light source module having a plurality of LEDs connected to a metal carrier (4) by means of an insulating layer (3). In order to afford protection against mechanical effects and in order to form a reflector, the LEDs are surrounded by a frame (10), which is segmented into a plurality of parts by expansion joints (13), in order that stresses occurring as a result of temperature fluctuations are absorbed.
