Intelligent light sensor of vehicle

Abstract

An intelligent light sensor of a vehicle comprises an original light sensation sensor, a variable light control module, an original relay and fuses connected in turn by an optical converter main circuit, and is characterized in that an optical converter further comprises an intelligent photosensitive module and a delay switch, the delay switch is arranged on a connection circuit between the original relay and the variable light control module, and the intelligent photosensitive module is composed of an additionally arranged light sensation sensor and two additionally arranged relays. The intelligent light sensor of the vehicle has the advantages of simple structure and convenience in use, traffic accidents caused by illegal use of high beams during running at night are effectively avoided, the intelligent light sensor of the vehicle is completely free from manual operation, and lights can be automatically turned on in the rainy weather, when the night falls or when the vehicle enters low-visibility places, such as underground garages and tunnels, so that full intelligent operation of variable light is realized.

Description

technical field [0001] The invention relates to a car lighting device, in particular to an intelligent car light sensor. Background technique [0002] At present, China's car ownership and use have greatly increased. However, when the car is driving at night, what bothers the driver the most is the strong light from the headlights of the driving vehicle. When the strong light shines, the driver's eyes will be completely white, and it is impossible to see the road conditions in front of him clearly. car accident. According to relevant statistics, about 70% of the traffic accidents that occur at night are caused by the illegal use of strong lights, which seriously affect vision due to the glare of the strong lights. In order to solve this problem, Wang Jiangtao (that is, the applicant of this patent) invented a "car light control headlight dimmer" (patent number: ZL201220178660.5), which is used in the high beam and low beam circuits of each vehicle Install light sensor, di...

AI Technical Summary

Problems solved by technology

Although this technology solves the problem of automatic dimming when meeting cars, there are still some shortcomings and deficiencies: 1. The light changing system will only be activated at night when it is irradiated by strong light. Intelligent lighting system during driving; 2. After the car is dimmed at night, if there is no delay function, when the strong light turns into low light, it will immediately turn back to strong light

This will cause frequent dimming of far and near light, which will cause discomfort to the driver and cause accidents.

3. Failure to turn on the headlights in time in rainy weather, nightfall or when entering underground garages, tunnels and other low visibility conditions will lead to unclear road conditions and easy to cause safety traffic accidents; 4. Inaccurate sampling of light sensors , it is easy to cause the sensor to detect the light intensity error

It will also cause frequent dimming on roads with street lights

5. The dimming system is cut into the lighting system of the original car. If there is a problem with the dimming system, the original lighting of the car will fail
