Problems solved by technology

[0002] At present, the lighting distance of the vehicle lights is mostly fixed in two stages, that is, the purpose of adjusting the lighting distance of the vehicle lights is achieved by manually switching the high beam and the low beam. However, due to the increase of the speed of the vehicle, driving Or the visual distance of the rider should also be increased so that the driver or rider has a longer time to react. Therefore, some people are often used to switching the high beam when driving or riding a car at night. To achieve the purpose of increasing the lighting distance of vehicle lights. However, if the high beam is used to meet cars, the light will directly shine on the other party, causing glare to the other party and affecting the line of sight, which will have a considerable impact on driving safety.

Embodiment Construction

[0026] Please refer to figure 1 , Figure 2A and Figure 2B As shown, the vehicle speed and light sensor type vehicle light illumination distance adjustment method of the present invention is to use a vehicle speed sensor 10, a front photometric sensor 11, an ambient photometric sensor 12, a controller 13, and a consistent Actuating device, a toggle switch 16 and a timer 17, wherein the actuating device can be an amplifying circuit, a motor driver 14 and a motor 15, and the motor 15 is installed on the outer cover 22 of a vehicle lamp, and has A rotating shaft 151 protrudes toward the inside of the outer cover 22. The outer cover 22 is provided with a reflector 21 located at an initial position, that is, a horizontal position. The reflector 21 is provided with a light bulb 20 electrically connected to the controller 13, so that the reflector 21 can be pushed to pivot when the rotating shaft 151 rotates. The combination of the reflector 21 and the rotating shaft 151 can be th...

Abstract

A speed sensor and a luminance sensor are adopted in the method to induce speed of vehicle and luminance in front of the vehicle. Based on speed and luminance detected, a controller controls motor to actuate reflecting bowl to adjust illumination distance. The invention reduces inconvenience for drivers to switch between headlights on full beam and dipped headlight so as to raise safety in driving car at night.

Description

technical field [0001] The present invention relates to a method for adjusting the lighting distance of a vehicle speed and light sensor, in particular to a vehicle speed and light sensor and a controller to sense the vehicle speed and the light intensity at the front end of the vehicle, and to control the same A method for adjusting the lighting distance of vehicle lights in real time by a moving device. Background technique [0002] At present, the lighting distance of the vehicle lights is mostly fixed in two stages, that is, the purpose of adjusting the lighting distance of the vehicle lights is achieved by manually switching the high beam and the low beam. However, due to the increase of the speed of the vehicle, driving Or the visual distance of the rider should also be increased so that the driver or rider has a longer time to react. Therefore, some people are often used to switching the high beam when driving or riding a car at night. To achieve the purpose of incre...
