Description

A kind of novel anti-lighting device of unblanking of forcing open the door

The utility model relates to a kind of anti-lighting device of unblanking of forcing open the door.

When people open the pick-proof door lock at night, do not grope the lockhole position in the dark because there being illumination often, open the door and feel very inconvenient.Once the someone invented the periphery subsides fluorescent paper at lockhole, played certain help to unblanking night.But the deficiency that exists is: fluorescent paper was given out light and is leveled off to zero when night was long slightly, had lost function of use.

The purpose of this utility model provides a kind of novel anti-lighting device of unblanking of forcing open the door, and can seek lockhole and provide convenience to opening anti-forcing open the door night, and lighting device cuts out automatically during unmanned or daytime, saves energy consumption.

The purpose of this utility model is achieved in that it comprises wiring board, the inductive head that is connected with wiring board and light activated thyristor, the battery case of band inductive switch circuit, its technical scheme main points are: assembling electroluminescent cell outdoors, electroluminescent cell is by the inductive switch circuit on the plate of wire connecting line road.

Above-mentioned electroluminescent cell outside installs transparent protective shield.

Operation principle; When night, human body was apart from 30 centimeters left and right sides of lockhole, the inductive head received signal also started the inductive switch circuit working, makes electroluminescent cell luminous, thereby makes the people can find the lockhole position easily.

The utility model has the advantages that: night human body can throw light on automatically when forcing open the door near anti-, light-emitting line is soft, makes the people can find the lockhole position easily, can close light source automatically after 20 seconds, device is closed to save energy consumption during unmanned or daytime; Install arbitrarily, conveniently.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is that the utility model is installed in a last schematic diagram.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is a kind of inductive switch circuit theory diagrams of the present utility model.

See Fig. 1-3, concrete structure is as follows: at the lockhole 4 other fixing assembling electroluminescent cells 5 of anti-2 the lateral surface 10 of forcing open the door, electroluminescent cell 5 can be made different shape or specific identity.The external stability assembling transparent protective shield 3 of electroluminescent cell 5, transparent protective shield 3 can adopt transparent plastic.Battery cases 6 are installed in anti-2 the inboard 11 of forcing open the door, and the circuit board 12 of assembling electronic component is installed in anti-forcing open the door in 2.Circuit board 12 and battery case 6 can be installed in arbitrary position of door, also can be installed on the doorframe, and electroluminescent cell 5 are by lead 9 connecting circuit plates 12.The inductive switch circuit that present embodiment adopts is the pyroelectric sensing circuit; Inductive head 8 adopts the pyroelectric sensing head.Open a loophole 1 in anti-11 the outside of forcing open the door, the photodiode 7 that is used for light activated thyristor is contained in loophole 1 inner side.The pyroelectricity inductive circuit is by forming near switch sections I and extraneous brightness detection and power pack II.Its operation principle is as follows; When there is the light time in the external world, photodiode 7 conductings, triode T4 ends, and T3 ends, and is in non-powered state near switch sections, and entire circuit is bordering on no current, so power consumption is extremely low.When the external world is unglazed, photodiode 7 ends, make triode T4 conducting, the T3 saturation conduction, connect power supply place armed state near switch sections, at this moment when human body near in 8 three ten centimeters of the inductive heads time, small-signal of inductive head 8 outputs, this signal enters by operational amplifier IC1-1, after 2000 times of amplifying circuits that IC1-2 forms amplified, signal entered impedance transformer IC1-3, timing capacitor C1 was discharged by diode D by the IC1-3 output stage, make timer IC1-4 output low level, convert high level to by triode T1 again, control light source switch pipe T2 saturation conduction provides bias current for oscillating tube T5, make the oscillating circuit starting of oscillation of the 4.5KJz of compositions such as T5 and transformer B, transformer secondary output will be exported 160V, 4, the alternating voltage of 5KHz, it is luminous to drive electroluminescent cell 5.After human body left, because of there not being above-mentioned induced signal, at this moment timing capacitor C1 made IC1-4 output high level by variable resistor RP and auxiliary charging circuit charging, makes light source switch pipe T2 end, and circuit recovers armed state.Inductive switch circuit of the present utility model also can adopt inductive switches such as existing microwave or photoelectricity.
