Description

Electronic power-saving device

The utility model relates to a kind of electric energy-saving device, the specifically a kind of electronic power-saving device that can save electric energy.

In the prior art; the storage battery illumination is directly bulb to be connect on the storage battery to light; its average discharge current is big; internal resistance of cell consumption is big; discharge time is short; battery life is also short; Chinese patent 87200189 discloses a kind of ac contactor silent Electricity-saving button, and it is a kind of ac contactor silent Electricity-saving button that the low pressure master makes control apparatus that belongs to; it comprehensively is an one with ac contactor silent electricity-saving appliance and push-button switch; it adopts resistance R to be serially connected in the DC circuit; protection diode D, its weak point is that power savings is not obvious.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of simple in structure, electronic power-saving device that power savings is good is provided.

To achieve these goals, the utility model provides a kind of new technical solution: this electronic power-saving device, mainly by shell, pulse-generating circuit and pulse power amplifier circuit are formed, pulse-generating circuit is by time-base integrated circuit NE555, diode D1, D2, capacitor C 1, resistance R 1, R2, potentiometer W forms, time-base integrated circuit NE555 is connected into the multivibrator form, its 1 pin ground connection, 4,8 pin also connect power supply, R3, C2 is decoupling filtering, 2,6 pin also connect, be the threshold voltage control end, resistance R 1, potentiometer W top, diode D1, capacitor C 1 forms charge circuit, resistance R 2, potentiometer W bottom, diode D2, time-base integrated circuit 7 pin form discharge loop, triode BG1, BG2 forms the pulse power amplifier circuit of compound amplification, and electrical appliance is serially connected on the collector electrode of triode.

Of the present utility model have a following advantage: simple in structure, power savings is obvious, and is easy to use.

Accompanying drawing is embodiment of the present utility model.

Fig. 1 is an electrical principle block diagram of the present utility model.

Fig. 2 is an electronic power-saving device circuit diagram of the present utility model.

Below in conjunction with drawings and Examples essentiality content of the present utility model is described in further detail.

This electronic power-saving device mainly is made up of shell, pulse-generating circuit and pulse power amplifier circuit.Pulse-generating circuit is made up of time-base integrated circuit NE555, diode D1, D2, capacitor C 1, resistance R 1, R2, potentiometer W, time-base integrated circuit NE555 is connected into the multivibrator form, its 1 pin ground connection, 5 pin skies connect need not, 4,8 pin and connect power supply, R3, C2 are decoupling filtering, 2,6 pin and connecing, be the threshold voltage control end, resistance R 1, potentiometer W top, diode D1, capacitor C 1 form charge circuit, change its value and can change the speed that threshold voltage occurs, thereby change the height of frequency of oscillation.Resistance R 2, potentiometer W bottom, diode D2, time-base integrated circuit 7 pin form discharge loop, change its value scalable output duty of ratio.Triode BG1, BG2 form the pulse power amplifier circuit of compound amplification, and electrical appliance is serially connected on the collector electrode of triode.In the use after energized, the circuit starting of oscillation, from the good huge ripple of the 3 pin output performances of time-base integrated circuit NE555, and the compound amplification of process BG1 and BG2, can make the bulb that is serially connected on its collector electrode obtain the high-power huge ripple that switching characteristic is fabulous, make bulb be operated on off state.Owing to adopt the compound of BG1 and BG2, can make BG2 obtain enough exciting currents, guarantee its thorough conducting when opening, thoroughly close during the pass, thereby its heating is very little, thereby has eliminated the power consumption of power supply in circuit.
