Problems solved by technology

[0003] In order to solve the problem of traffic accidents caused by turning on the high beam lights for a long time when the existing motor vehicles meet at night, the purpose of the present invention is to provide a front of the motor vehicle that forces the motor vehicles to automatically change the high beam lights to the low beam lights. Headlight automatic dimming device, so as to ensure safe driving when meeting cars at night

Abstract

The invention relates to a vehicle headlight auto light altering device that includes voltage regulator circuit, MCU, signal emitting and receiving circuit, testing circuit, safety alarming circuit, light altering executing circuit, and advancing light altering control circuit. It is installed under engine cover and wheel house, and is connected to ignition switch, dipped headlight, and high beam. Once one vehicle lights dipped headlight, the other would switch to dipped headlight automatically from high beam. Thus, the safety would be ensured. The device is easy to install and works reliably. It would not influence other function of the vehicle.

Description

technical field [0001] The invention relates to a circuit used in an optical lighting device of a motor vehicle, in particular to an automatic light-dimming device for a headlight of a motor vehicle. Background technique [0002] Motor vehicle headlights have two illumination functions of high beam and low beam. When a motor vehicle is running normally at night, it is generally illuminated with high beams. When two vehicles meet, in order to prevent the high beams from being dazzled and avoid traffic safety accidents arising therefrom, the Ministry of Communications has stipulated on motor vehicle safety: motor vehicles at night When meeting vehicles, at a distance of 150M, both sides of the meeting vehicle should actively change the headlights to low beam lighting. Because the change of the far and low beams of the motor vehicle is manually controlled by the driver, due to the driver's negligence and low quality , Malicious opening and other reasons, at present, the safety...
