Lighting device for a motor vehicle with a safety device for detecting fault conditions and method for detecting fault conditions

摘要

The invention relates to a lighting device (10) for a motor vehicle having a laser light source (16) which is adapted to emit light (16a), comprising a reflector (14) comprising a reflection side (14a) adapted to supply light and an electrically conductive layer, and an outer side (14b) facing away from the reflection side (14a) and disposed opposite to each other. Furthermore, the illumination device has a safety device (12) for detecting fault states of the illumination device (10). The safety device (12) has at least one inductive sensor (12a) which is arranged on the outside with respect to the reflector (14), so that the outside (14b) of the reflector (14) faces the inductive sensor (12a) and the Reflection side (14a) of the reflector (14) facing away from the inductive sensor (12a), wherein the safety device (12) is adapted by means of the inductive sensor (12a) a temperature change of at least a portion of the reflection side (14a) of the reflector (14) capture.
