Abstract

The utility model belongs to the photoelectric control field. The utility model is used to control the brightness of head lights of an automobile of the other party. An amplifier mainly composed of a photoelectric converter D1, a photoelectric converter BG1 and a photoelectric converter BG2, a relay J and a signal transmitter F convert light signals of the automobile of the party A into infrared light signals to be emit out. The infrared light signals emitted by the party B are converted into electrical signals by an amplifier composed of an infrared light signal converter D3, an infrared light signal converter BG3 and an infrared light signal converter BG4 in an automatic control dimmer of the other party, a delay relay S and a delay relay SJ, and high beam of the light of the other party is converted into passing light so as to form cross mutually-closed light to run. The utility model can control the change of the light of the automobile of the other party automatically. The danger caused by the dazzling light of the party B can be prevented.

Description

The automatic guidance Dim Dimmer

Affiliated technology territory:

The utility model belongs to the photoelectric control field

The utility model is used for controlling the other side's automobile front lamp distance light dimming.

Figure viewed from behind technology:

The Dim Dimmer of vehicle use at present is a manually operated, and labour intensity is big, is difficult for the as prescribed operation, and it is not untimely to become light, causes danger easily.

Summary of the invention:

In order to reduce the labour intensity of chaufeur, improve the safety of vehicle night travel, the utility model provides a kind of automatically controlled to become fairing, and this Dim Dimmer can change the other side's automobile front lamp distance light dimming automatically, and light is dazzling causes danger in prevention.The technical scheme that the utility model adopted is:

The energized switch, power supply is by slug relay's armature contact, distance light contacting infrared signal transmitter power, it can be controlled both sides' vehicle intersection and close change light mutually, and a little less than the light, photodiode is subjected to a little less than the light when both sides' vehicle apart from each other, resistance is big, the multiple unit tube conducting that aerotron BG1 and BG2 form, relay disconnects, and the infrared signal projector is not launched, light is strong when two cars are nearer apart, photodiode is subjected to light intensity resistance little, and multiple unit tube ends, and relay is connected, the infrared signal projector transmits, the infrared photodiode of the other side's vehicle is subjected to me strong, and resistance is little, and the multiple unit tube of triode BG3 and BG4 combination ends, the S of slug relay connects and time-delay, the driving SJ of slug relay armature contact is shifted to place, dipped beam contact by place, distance light contact, and time-delay, and this moment is bright owing to the other side's vehicle Dim Dimmer is in passing light, the infrared signal projector can not transmit, if this moment, square vehicle light was very strong, the square vehicle of control that can not transmit becomes light, prevents two cars to become light simultaneously.After finishing, the time-delay of the other side's vehicle dipped beam is in distance light time-delay state, this moment, (delay time of previous slug relay equaled back slug relay's distance light under the effect of the previous S of slug relay, the time-delay sum of dipped beam), although square the other side's vehicle that transmits can not become dipped beam from distance light, and this moment is if square vehicle light is very strong, the photodiode of the other side's vehicle is subjected to light intensity, resistance is little, multiple unit tube ends, relay is connected the infrared signal transmitter power, transmit, the infrared photodiode of square vehicle is subjected to light intensity resistance little, multiple unit tube ends, the S of slug relay connects and time-delay, driving the SJ of slug relay makes its armature contact be moved and time-delay to place, dipped beam contact by place, distance light contact, after time-delay finishes, be in distance light time-delay state, this moment is if the other side transmits and can not control square automobile front lamp distance light and become dipped beam, if this moment, the other side's vehicle light was still very strong, its distance light time-delay state finishes, recover normal condition, although can both transmit with the side this moment, but square vehicle is in distance light time-delay state, become dipped beam by distance light again so can only control the other side's vehicle, so analogize, just can realize that both sides close intersection mutually and become light, prevent to become simultaneously light or constant influence of light safety traffic, reduce the labour intensity of chaufeur.

Below in conjunction with drawings and Examples the utility model is further specified.
