Abstract

The utility model relates to a night vision license plate of a motor vehicle, which belongs to a license plate of a motor vehicle. The night vision license plate of the motor vehicle comprises a license plate shell made of transparent plexiglass, the inner wall of the front face of the license plate shell is provided with a license number printed with a fluorescent paint, a circuit board is arranged behind the number, and a light-emitting diode is fixed on the circuit board. The utility model has the beneficial effect that the visual range of the license place of the motor vehicle is more than 30 meters at night. The night vision license plate of the motor vehicle has a reasonable circuit design, a simple structure, low power consumption, a long service life and a production cost, and can facilitate the promotion.

Description

Self-propelled vehicle night vision car plate

Technical field:

The utility model relates to a kind of automobile license plate.

Background technology:

At insufficient light or do not have on the road of street lamp and walk, run into the self-propelled vehicle of A car sped night, can be greatly disturbed; And, can't see the number-plate number clearly.If run into the self-propelled vehicle accident, and the accident car escape, then can bring difficulty to tracing vehicle because of seeing the number-plate number of accident car clearly.

Summary of the invention:

The purpose of this utility model is that a kind of self-propelled vehicle night vision car plate will be provided.Self-propelled vehicle night vision car plate is the car plate housing that adopts transparent organism glass to make, and with the fluoroleum lacquer print system number-plate number, establishes wiring board in the number back on the car plate housing front inside wall, fixing light-emitting diode on the wiring board.Light-emitting diode does not work by day, and light evening automatically.By the car plate of led lighting, its, visual range was greater than 30 meters at night.

Self-propelled vehicle night vision car plate is the car plate housing that adopts transparent organism glass to make, and with the fluoroleum lacquer print system number-plate number, establishes wiring board in the number back on the car plate housing front inside wall, fixing light-emitting diode on the wiring board.

The circuit that self-propelled vehicle night vision car plate adopts is seen accompanying drawing 2, circuit+,-end connects the 12V direct supply.By day, because photoconductive cell RG is subjected to the irradiation of natural daylight, present low resistance; The base potential of aerotron VT is low, and by reverse bias, so VT ends, and one-way SCR VS gate pole is that low level is turned off, and LED does not work.After darkness, photoconductive cell RG presents high value because of unglazed photograph, the VT conducting, and the gate pole of one-way SCR VS promptly has the forward trigger voltage and conducting, the LED electrified light emitting.

K switch is a hand control switch, as long as the K closure, no matter day and night, LED all can be luminous.

The beneficial effect that adopts self-propelled vehicle night vision car plate be make self-propelled vehicle car plate night visual range greater than 30 meters.The circuit layout of self-propelled vehicle night vision car plate is reasonable, simple in structure, and it is very little to consume electric energy, long service life, and productive costs is low, is beneficial to promote the use of.

Description of drawings:

Fig. 1 is the structural representation of self-propelled vehicle night vision car plate;

Fig. 2 is the circuit diagram of self-propelled vehicle night vision car plate.

The specific embodiment:

With reference to Fig. 1, self-propelled vehicle night vision car plate is the car plate housing 1 that adopts transparent organism glass to make, and with the fluoroleum lacquer print system number-plate number 2, establishes wiring board 4 in number 2 back on car plate housing 1 front inside wall, fixing light-emitting diode 3 on the wiring board 4.

With reference to Fig. 2, circuit+,-end connects the 12V direct supply.By day, because photoconductive cell RG is subjected to the irradiation of natural daylight, it is on duty to present low-resistance; The base potential of aerotron VT is low, and by reverse bias, so VT ends, and one-way SCR VS gate pole is that low level is turned off, and LED does not work.After darkness, photoconductive cell RG presents high value because of unglazed photograph, the VT conducting, and the gate pole of one-way SCR VS promptly has the forward trigger voltage and conducting, the LED electrified light emitting.

Claims

1. self-propelled vehicle night vision car plate is by the car plate housing, the number-plate number that useful fluorescence paint is printed on the car plate housing front inside wall, constitute with the light-emitting diode that is located at the number back, it is characterized in that the car plate housing (1) that self-propelled vehicle night vision car plate adopts transparent organism glass to make, use the fluoroleum lacquer print system number-plate number (2) on the inwall in car plate housing (1) front, establish wiring board (4) in number (2) back, wiring board (4) is gone up fixedly light-emitting diode (3).
