Setting procedure based on a PBS beam splitter for the adaptive high beam function and its intelligent vehicle light module

摘要

The invention relates to a setting method based on a PBS beam splitter for the adaptive high beam function and its intelligent vehicle light module. The intelligent vehicle light module integrated with a camera contains an intelligent light control system, which consists of a light source system and light control elements. Part of the light emitted by the intelligent lighting control system passes through the PBS beam splitter and forms the illuminating light shape. Another part of the light emitted by the intelligent light control system is reflected by the PBS beam splitter in the opposite direction of the integrated circuit with light-sensitive chips in order to prevent the light from interfering with the light-sensitive chips. The ambient light enters the imaging lens group in the reverse direction of the illumination light path. Some of the ambient light is reflected from the PBS beam splitter to the light sensitive chip integrated circuit to form the source of information for the light control system to perform dynamic control. The illuminating light emitted from the light source creates a light shape on the front vertical screen. The light source is moved relative to the lens and switched off in a certain position, while it remains switched on in the remaining positions. As a result, a light shape with a dark zone is formed on the front vertical screen, as a result of which the adaptive high beam function is set. The aforementioned integrated intelligent module can reduce the source of error.
