Abstract
The invention provides a self-induction desk lamp control device. The circuit of the self-induction desk lamp control device comprises an HC-SR501 human body induction module, a 555 integrated circuit U1, a photoresistor LDR, a potentiometer RV1, a resistor R1, a resistor R2, a diode D1, a diode D2, a diode D3, a capacitor C1, a relay RL1 and a switch S1. The self-induction desk lamp control device utilizes the photoresistor and the human body induction module to detect the ambient light and perceive the human body respectively so as to automatically control the switch of the desk lamp. When the natural light in the room is insufficient and people studies before a desk, the desk lamp can be automatically turned on so that the vision of a child can be effectively protected, and at the same time the desk lamp can be turned off automatically so that electrical energy saving can be realized automatically when the people leaves the desktop.
Description
Technical field
The present invention relates to a kind of desk lamp control device of automatic inductive switch, belong to application electric technology field.
Background technology
Nowadays the child of many families has independent study room; sometimes because the carelessness of the head of a family; child does not understand the eyes of protection oneself in learning process; time particularly at candlelight light splitter is dimmed gradually; active consciousness is not had to go to open the desk lamp on table; be often continue to learn under dim environment, easily like this bring great injury to eyes.Therefore; be necessary to design a kind of desk lamp control device; when room available light is not enough; and when having people to learn before desk, desk lamp can be opened automatically, thus can play the effect of available protecting child eyesight; simultaneously; after people leaves desktop, desk lamp can be closed voluntarily, automatically realizes electrical energy saving.
Summary of the invention
The object of this invention is to provide a kind of self-induced desk lamp control device, with the injury preventing child from may cause eyesight at dim light learning.
The concrete technical scheme that the present invention takes is as follows:
A kind of self-induced desk lamp control device, is characterized in that: the circuit of described desk lamp control device comprises HC-SR501 human body induction module, 555 integrated circuit U1, photo resistance LDR, potentiometer RV1, resistance R1 and R2, diode D1, D2, D3, electric capacity C1, relay R L1, switch S 1; One end of one end of resistance R1 and R2,4 pin of 555 integrated circuit U1 and 8 pin, the negative pole of diode D3, the coil of relay R L1 is accessed respectively after+5V power series switch S 1; The other end of the positive pole of diode D3 and the coil of relay R L1 accesses 3 pin of 555 integrated circuit U1 jointly; One stiff end of another termination potentiometer RV1 of resistance R1, another stiff end and the adjustable side parallel connection of potentiometer RV1 are connected the negative pole of diode D1 and one end of photo resistance LDR afterwards, the other end ground connection of photo resistance LDR, the other end of resistance R2 and the negative pole parallel connection of diode D1, D2 access 2 pin of 555 integrated circuit U1 afterwards; The VCC pin of HC-SR501 human body induction module connects+5V power supply, and OUT pin connects the negative pole of diode D2, GND pin ground connection; The 1 pin ground connection of 555 integrated circuit U1,6 pin are connected with 2 pin, ground connection after 5 pin serial capacitance C1; One group of normally opened contact of relay R L1 is as the output of this circuit.
Beneficial effect of the present invention is: this self-induced desk lamp control device utilizes photo resistance and human body induction module testing environment light and perception human body respectively, and then the switch of automatic control console lamp.When room available light is not enough, and when having people to learn before desk, desk lamp can be opened automatically, thus can play the effect of available protecting child eyesight, and meanwhile, after people leaves desktop, desk lamp can be closed voluntarily, automatically realizes electrical energy saving.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the desk lamp control device of this automatic inductive switch.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the circuit of this self-induced desk lamp control device comprises HC-SR501 human body induction module, 555 integrated circuit U1, photo resistance LDR, potentiometer RV1, resistance R1 and R2, diode D1, D2, D3, electric capacity C1, relay R L1, switch S 1; One end of one end of resistance R1 and R2,4 pin of 555 integrated circuit U1 and 8 pin, the negative pole of diode D3, the coil of relay R L1 is accessed respectively after+5V power series switch S 1; The other end of the positive pole of diode D3 and the coil of relay R L1 accesses 3 pin of 555 integrated circuit U1 jointly; One stiff end of another termination potentiometer RV1 of resistance R1, another stiff end and the adjustable side parallel connection of potentiometer RV1 are connected the negative pole of diode D1 and one end of photo resistance LDR afterwards, the other end ground connection of photo resistance LDR, the other end of resistance R2 and the negative pole parallel connection of diode D1, D2 access 2 pin of 555 integrated circuit U1 afterwards; The VCC pin of HC-SR501 human body induction module connects+5V power supply, and OUT pin connects the negative pole of diode D2, GND pin ground connection; The 1 pin ground connection of 555 integrated circuit U1,6 pin are connected with 2 pin, ground connection after 5 pin serial capacitance C1; One group of normally opened contact of relay R L1 is as the output of this circuit.
When this self-induced desk lamp control device uses, the output of its circuit is sealed in desk lamp power supply circuits, after the S1 that closes a switch, when daytime is bright and clear, photo resistance LDR resistance is very little, diode D1 conducting, 2 pin of 555 integrated circuit U1 and 6 pin maintain low level, because 555 integrated circuit U1 constitute a flip and flop generator, when its 2 pin input low level, then 3 pin export high level, relay R L1 coil no power, and desk lamp keeps OFF state; When after dim the dusk time-division, photo resistance LDR resistance sharply increases, diode D1 ends, and when now having people to learn before desk, HC-SR501 human body induction module detects human body, its OUT pin exports high level, diode D2 ends, now the 6 pin input high levels of 555 integrated circuit U1, triggers its 3 feet state and is turned into low level, the coil electricity of relay R L1, desk lamp is lighted automatically; After people leaves desktop, HC-SR501 human body induction module can't detect human body, and its OUT pin exports and becomes low level, and the 3 pin upsets triggering 555 integrated circuit U1 are high level, the coil blackout of relay R L1, desk lamp automatic distinguishing.
