Headlight, vehicle with headlight and method for monitoring a headlight
A headlight featuring a laser light source and a converter for converting a short-wave laser beam generated by the laser light source into white light. The headlight also includes a light-forming element for creating a beam path using the white light of the laser light source, as well as an IR sensor for measuring the IR radiation generated by the converter.
1. A headlight comprising:
a laser light source;
a converter for converting a short-wave laser beam generated by the laser light source into white light;
