The invention relates to an AFS (Atomic Fluorescence Spectroscopy) system and method for dimming a full-LED (Light-Emitting Diode) matrix. The AFS system comprises a main ECU (Electronic Control Unit), a first power ECU, a second power ECU, a first LED light unit and a second LED light unit, wherein the main ECU is used for realizing acquisition and receiving of traveling signals, calculating the received relevant signals, and respectively outputting control signals to the first power ECU and the second power ECU lastly; and the first LED light unit and the second LED light unit are used for turning on different LED lamp beads according to output power control signals of the first power ECU and the second power ECU respectively, and overlapping to form an entire light shape which is accordant with a light grading standard. According to the AFS system for dimming the full-LED matrix, a high-power LED light source matrix is adopted instead of the conventional mechanical adjusting way, so that self-adaptive illumination can be realized only through power control; and a series of problems caused by the precision and abrasion of a mechanical adjusting device are solved, and a self-adaptive front illumination system with high precision, high efficiency and long service life is realized.
Description
technical field [0001] The invention belongs to the technical field of automobile lighting, and more specifically, the invention relates to an AFS system and method for full LED matrix dimming. Background technique [0002] With the development and progress of society, the surrounding environment where cars drive becomes more and more complex. The speed limit of different roads is different, the lighting of the road is different, the density of pedestrians is different, and the weather conditions are different, so that the traditional headlights with only two lighting modes of low beam and high beam can no longer meet people's growing driving safety. need. For this reason, an adaptive front lighting system, namely the AFS system, came into being. This system can automatically adjust the light distribution method according to the surrounding environment, provide a larger lighting range and lighting distance, and at the same time improve the lighting dead angle of the headlig...
