Abstract

The utility model discloses an automatic light alternating device of a vehicle lamp. Three terminals at the tail end of the vehicle lamp of the device are connected respectively with a battery cathode, a strong current circuit, which is arranged at the internal side of the windscreen and an optical sensing switch of which is at the state of normal closing, and a weak current circuit, an optical sensing switch of which is at the state of normal opening. The other end of the optical sensing switch is connected with a battery anode. When two vehicles are running oppositely at night, strong light mutually senses an electric sensing switch in the opposite vehicle to make the strong light alternated into the weak light, which does not stimulate eyes of a driver and reduces traffic accidents.

Description

The car light automatic device for changing light

One, technical field:

The utility model relates to a kind of device of light intensity of automatically regulating car light, be applicable to the lighting regulation on the various vehicles.

Two, background technology:

Before the utility model proposes, the various vehicles of night running, relatively and row soon near the time, the high light of car light stimulates driver's eyes, makes the driver see not clear the place ahead, occurs traffic accident easily.

Three, summary of the invention:

Technical problem to be solved in the utility model provides a kind of night travel vehicle of coming of opposite does not stimulate the car light automatic device for changing light of driver's eyes.

Solving the problems of the technologies described above the technical scheme that is adopted is: negative pole that connects storage battery of three binding posts of car light tail end, a heavy current circuit that is in normally off with the photoinduction switch that is installed in the inboard relevant position of windscreen before the car joins, a dry circuit that is in normally open with the photoinduction switch joins, and the other end of its photoinduction switch connects the positive pole of storage battery by beginning.When night the opposite travel the vehicle light that comes by force when to a certain degree shining windshield, the heavy current circuit automatic cutout in the photoinduction switch, dry circuit connection simultaneously makes car light become the low light level automatically; Heavy current circuit after car leaves in the photoinduction switch is connected automatically, makes car light recover high light automatically.

Compared with prior art the utility model is just installed a photoinduction switch between car light and storage battery, under the effect of photoinduction switch, make car light transfer the low light level to by high light automatically behind the switch on, the vehicle that comes does not stimulate driver's eyes thereby travel in realization opposite at night, reduces the generation of traffic accident.

Four, description of drawings:

Fig. 1 is the circuit diagram of the utility model car light automatic device for changing light.

Five, the specific embodiment:

Car light tail end in the utility model car light automatic device for changing light has three binding posts 5,6,7.Binding post 5 connects the negative pole of storage battery 4, binding post 6 joins with the heavy current circuit that the photoinduction switch that is installed in the inboard relevant position of car front windshield glass is in normally off, binding post 7 joins with the dry circuit that photoinduction switch 2 is in normally open, the other end of photoinduction switch 2 joins by switch 3 and storage battery 4 positive poles, thereby just constitutes a car light automatic device for changing light.This device must be installed on two vehicles that travel relatively simultaneously, and the photoinduction switch on two cars of relatively exercising night just makes car light become the low light level (dipped beam) automatically after receiving the other side's high light (distance light), transfers high light automatically again to after missing car.

Claims

1, a kind of car light automatic device for changing light, it is characterized in that the car light tail end has three binding posts (5,6,7), binding post (5) connects the negative pole of storage battery (4), binding post (6) joins with the heavy current circuit that the photoinduction switch (2) that is installed in the inboard relevant position of car front windshield glass is in normally off, binding post (7) joins with the dry circuit that photoinduction switch (2) is in normally open, and the other end of photoinduction switch (2) joins by the positive pole of switch (3) with storage battery (4).
