Abstract
The utility model discloses an automatic dimming device for the automobile light. The circuits of the automobile lights DW-[1] and DW-[2] are connected with a photoelectric tube RS, an adjustable resistor R, a controllable silicon SCR and an electric relay J. When the automobile lights DW-[1] and DW-[2] which are in work are irradiated by the strong light, the photoelectric tube RS can receive the electrooptical signal and output the signal quickly. The controllable silicon makes the electric relay J work through the communication of the resister R, to change the parallel connection status of the automobile lights DW-[1] and DW-[2] into the connection in series status, lowering the working voltage, weakening the lamp light and achieving the purpose of the safe meeting of the motor vehicles in the night.
Description
The utility model belongs to the lighting regulation technology, and car light light automatically regulating becomes the technology of light when being specifically related to self-propelled vehicle night running meeting.
In actual life, the power actuated vehicle of night running (especially heavy-duty freight car) is a lot, and therefore, dealing motor vehicle driving personnel Chang Yin the other side car light light is crossed strong and influenced sight line, causes the traffic accident accident that should not take place and is subjected to massive losses.
For reducing motor-driven vehicle going traffic accident at night accident, improve the safe driving rate, ad hoc meter the utility model, it can make the power actuated vehicle of night running when meeting, both sides' car light light all weakens, be unlikely making navigating mate sight stimulated by high light,, avoid traffic accident to take place with accurate grasp travel way.
Below in conjunction with the circuit interconnect pattern that provides in the accompanying drawing, describe concrete structure of the present utility model and principle of work in detail.DW in the accompanying drawing
1And DW
2Expression self-propelled vehicle fwd two car lights, in its circuit, inserting electro-optical tubes RS, adjustable resistance R(by electric connecting mode is the load resistor of electro-optical tubes RS), controllable silicon SCR and relay J.When the self-propelled vehicle cruising need throw light on, two car light DW
1And DW
2Locate state in parallel, the operating voltage of its every lamp is 12V, can sends the intense light irradiation road.When the organic motor-car meeting in the place ahead, in running order car light DW
1And DW
2Owing to be subjected to the irradiation of the other side's car light high light, electro-optical tubes RS in the circuit receives behind the photosignal output signal rapidly, this signal is delivered to the controllable silicon SCR trigger electrode through adjustable resistance R, when this energizing signal reaches certain value, controllable silicon SCR is conducting, and the charged adhesive of the coil that makes relay J, and the contact J of relay J
2-1And J
2-2Disconnect J
1-1Closure, car light DW like this
1And DW
2Mode of operation then become series connection by parallel connection, so its operating voltage becomes 6V by 12V, light is weakened greatly, to reach the purpose of safe meeting.
In addition, remind navigating mate to notice that the place ahead sends a car in order to report to the police with buzzing, should careful operation, in circuit, insert buzzer phone Y again, it is in the relay J action, makes contact J
1-1In the time of closed, make contact J
1-2Also rapid closing and beginning is sounded a buzzer and is reported to the police.
The utility model is simple in structure, and is with low cost, easy for installation, can make night running self-propelled vehicle safety meeting effectively, is a kind of new design of benefiting the nation and the people.
Claims (2)
1, a kind of automotive lamp automatic dimmer comprises car light DW
1And DW
2, it is characterized in that at car light DW
1And DW
2Circuit in insert electro-optical tubes RS, adjustable resistance R, controllable silicon SCR and relay J, car light DW by being electrically connected
1And DW
2Be subjected to strong illumination, electro-optical tubes RS to receive behind the photosignal output signal rapidly, send controllable silicon SCR trigger electrode and conducting controllable silicon SCR through resistance R, the charged adhesive of relay J coil, contact J
2-1And J
2-2Disconnect J
1-1Closure, car light DW
1And DW
2Become series connection and reduce operating voltage.
2,, it is characterized in that also being connected in the above-mentioned circuit buzzer phone Y according to the described Dim Dimmer of claim 1.
