  "textContent": "A light module for automotive headlights is presented, comprising a laser light source (1) that generates a primary laser beam, a photoluminescence converter (4) that is arranged in the primary laser beam and is excited by the laser light to photoluminescence and emits a secondary light distribution (10) generated by utilizing the photoluminescence via a radiation surface of the converter, a detection device arranged in the secondary light distribution, which is configured and arranged to detect an increase in the radiation intensity that falls on the detector (8) and to compare it with a safety limit value and which is configured to stop the generation of the laser beam. The light module is characterized in that the detection device comprises an imaging optical system (7b) that is configured to record a distribution of the radiation intensity over the radiation surface of the converter and to determine a change in the radiation intensity occurring in a partial area of the radiation surface and to perform the comparison with a safety limit value for at least one of the partial areas individually.",
