Abstract

The invention provides an intelligent laser vehicle lamp system and a detection method thereof. The intelligent laser vehicle lamp system is used for detecting an initial light source and outputting avehicle lamp light source; the intelligent laser vehicle lamp system comprises a vehicle lamp shell, an optical unit and a light leakage detection unit; the optical unit is arranged on a vehicle lampshell; the initial light source illuminates the optical unit; the optical unit is illuminated by the initial light source to excite a stable light source which advances along a stable light source path; the light leakage detection unit is arranged on the vehicle lamp shell and comprises an oval reflection surface and a light detector; the oval reflection surface is provided with the oval reflection surface focus; the oval reflection surface is adjacent to the corresponding optical unit; the oval reflection surface and the stable light source path are arranged at an interval; and the light detector is arranged on the oval reflection surface focus. Therefore, laser light leakage is detected by utilizing the focus feature of confocal multi-ellipses and the oval reflection surface, and a driver can be warned about the situation that the vehicle lamp system is abnormal.

Description

technical field [0001] The invention relates to a laser vehicle light system and a detection method thereof, in particular to an intelligent laser vehicle light system and a detection method thereof which use a specially structured ellipse reflective surface to collect and detect spectrum drift of laser light leakage. Background technique [0002] In the currently known car lighting systems, most of the technologies use traditional light sources, while LED light sources are equipped with higher unit price models, and laser lights are configured for a small number of mass-produced models. Laser headlights are characterized by energy saving, small size, brighter light, and longer lighting distance. For Advanced Driver Assistance Systems (ADAS), the working range of image recognition can be farther. Improve safety and respond to technological development trends such as energy saving, environmental protection, safety, and innovation. [0003] The laser light source is different...
