Accompanying drawing explanation
Fig. 1 is the circuit diagram of LED stroboscopic lamp.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of LED stroboscopic lamp, comprises triode V1, chip IC 1, potentiometer RP1 and chip IC 1, the collector electrode contact resistance R1 of described triode V1, LED H, power supply VCC, the pin 4 of chip IC 1, the pin 8 of chip IC 1 and the pin 8 of chip IC 2, the emitter of triode V1 connects a stiff end of potentiometer RP1, and the sliding end of potentiometer RP1 connects the pin 2 of chip IC 1, the pin 6 of chip IC 1 and electric capacity C1, the other end of electric capacity C1 connects electric capacity C2, electric capacity C3, another stiff end of potentiometer RP1, the pin 1 of chip IC 1, the pin 1 of chip IC 2 and the negative electrode of unidirectional thyristor Q1, the pin 5 of chip IC 1 connects the other end of electric capacity C2, and the pin 3 of chip IC 1 connects the pin 4 of chip IC 2, and the other end of resistance R1 connects the negative electrode of diode D1, a stiff end of potentiometer RP2 and the sliding end of potentiometer RP2, another stiff end of potentiometer RP2 connects electric capacity C4, the anode of diode D1, the pin 2 of chip IC 2 and the pin 6 of chip IC 2, the other end of electric capacity C4 connects the other end of electric capacity C3 and the pin 5 of chip IC 2, and the pin 3 of chip IC 2 connects the control pole of unidirectional thyristor Q1, and the anode of unidirectional thyristor Q1 connects the other end of LED H.
The model of chip IC 1 and chip IC 2 is NE555.Triode V1 is phototriode.
Operation principle of the present utility model is: IC1 forms photoelectric control circuit, and IC2, Q1 etc. form frequent flashing control circuit.Daytime, light was comparatively strong, phototriode V1 low-resistance, and power supply VCC, by RP1 dividing potential drop, makes 2 of IC1,6 pin current potentials be greater than 2/3VCC, 3 pin of IC1 export as low level, and IC2 reset terminal 4 pin is low level, and IC2 is blocked, oscillating circuit does not work, and Q1 is in off-state, and LED H is not luminous.At dusk light weakens gradually, and triode V1 resistance increases gradually, and 2 of ICl, 6 pin current potentials are progressively declined, when drop to be less than 1/3VCC time, 3 pin of IC1 export and are uprised by low, and 4 pin of IC2 are pulled to high level.The starting of oscillation of IC2 square-wave oscillator circuit, 3 pin of IC2 export ultralow frequency square-wave signals, Q1 conducting between pulse signal high period, and LED group H is luminous, and between low period, Q1 turns off the LED group H being and extinguishes, and regulator potentiometer RP2 conveniently can regulate flashing rate.
