Description

Electronic energy-saving swtich

A kind of energy-saving electronic switch that is used for corridor, lavatory, entrance hall, warehouse and temporary needs illumination at night.

Before the present invention makes, control the illumination of various public places with dark formula switch of traditional mechanical and pulling switch, its shortcoming is to turn off the light automatically, can cause a large amount of wastes and the bulb of electric energy very easily to damage like this.

The objective of the invention is to develop a kind of energy-saving electronic switch that can be applicable to the temporary needs illumination of various public places, it can play energy-conservation and prolong the bulb dual purpose of service time.

Energy-saving electronic switch of the present invention is made up of signal receiving unit, timing unit, trigger element and electronic switch and power subsystem.

Energy-saving electronic switch of the present invention can be applicable to the public place and the family of various corridors, lavatory, entrance hall, warehouse and temporary needs illumination at night, and have simple in structure, volume is little, in light weight, power saving is more than 80%, can prolong existing bulb service time, cost is low, with wiring of standard machinery switch and the equal mutually advantage of installation.

Be one embodiment of the present of invention below:

Fig. 1 is an electrical schematic diagram.

Fig. 2 is product structure figure.

As shown in Figure 1: exchange 220 volts by behind the bulb, form bridge rectifier by crystal two utmost points ［ 1 ］, ［ 2 ］, ［ 3 ］, ［ 4 ］.Resistor ［ 5 ］, crystal diode ［ 6 ］, voltage-stabiliser tube ［ 9 ］, capacitor ［ 10 ］, ［ 11 ］ are undertaken step-down, filtering, voltage stabilizing respectively, and one 12 volts direct voltage is provided for entire circuit.Thyristor ［ 7 ］ is undertaken electronic switch simultaneously, and its control signal obtains with transistor ［ 37 ］ junction from amplifier ［ 12 ］ or resistor ［ 38 ］ by resistor ［ 8 ］.

Voice signal receives by amplifier ［ 30 ］, pick up element ［ 34 ］, and resistor ［ 31 ］, ［ 32 ］, ［ 33 ］, ［ 36 ］, capacitor ［ 35 ］ is formed.Pick-up element ［ 34 ］ is accepted extraneous various sound, after amplifier ［ 30 ］ amplifies, for the acoustic control timing unit provides a timing voltage.

The acoustic control timing unit is by comparator ［ 24 ］, resistor ［ 25 ］, ［ 26 ］, ［ 27 ］, and capacitor ［ 28 ］, crystal diode ［ 29 ］ is formed.By crystal diode ［ 29 ］ rectification, giving regularly, capacitor ［ 28 ］ provides a timing voltage through the voice signal after amplifying.When intensity of sound surpassed certain limit, comparator ［ 24 ］ upset was for comparator ［ 12 ］ provides a high level.

The acoustic control trigger element is by comparator ［ 12 ］, ［ 21 ］, light-sensitive element ［ 17 ］, and resistor ［ 13 ］, ［ 15 ］, ［ 16 ］, ［ 18 ］, ［ 19 ］, ［ 20 ］, crystal diode ［ 14 ］ is formed.When comparator ［ 24 ］ output high level, can comparator ［ 12 ］ overturn and be determined by comparator ［ 21 ］.Comparator ［ 21 ］ is controlled by light-sensitive element ［ 17 ］ again.Comparator on daytime ［ 21 ］ output high level is given comparator ［ 12 ］, so comparator ［ 12 ］ output low level, controllable silicon ［ 7 ］ is in off status, and lamp does not work.Night, said process was then opposite, and controllable silicon ［ 7 ］ is in out state, and lamp is bright.The bright time length of lamp is by capacitor ［ 28 ］ and resistor ［ 27 ］ decision.

The touch unit is by transistor ［ 41 ］, ［ 45 ］, resistor ［ 42 ］, and ［ 43 ］, ［ 44 ］, ［ 47 ］, ［ 48 ］, ［ 49 ］, capacitor ［ 46 ］, sheet metal ［ 50 ］ is formed.When sheet metal ［ 50 ］ was arrived in the human body touch, its induced signal amplified by transistor ［ 45 ］, ［ 41 ］.For touch regularly provides a timing voltage.

Touch timing unit and trigger element be by transistor ［ 37 ］, resistor ［ 38 ］, capacitor ［ 39 ］, and crystal diode ［ 40 ］ is formed.Through the touch signal after amplifying, by crystal diode ［ 40 ］ rectification, giving regularly, capacitor ［ 39 ］ provides a timing voltage.This timing voltage provides the signal of turning on light through resistor ［ 8 ］ for controllable silicon ［ 7 ］ after amplifying through transistor.The bright time length of lamp is by capacitor ［ 39 ］ and resistor ［ 38 ］ decision.

Owing to have These characteristics, the present invention can produce various acoustic controls, light-operated, touch switch.And can often produce open, unit switch that Chang Guanyu regularly combines.

Fig. 2 is the structure chart of energy-saving electronic switch, and ［ 51 ］, ［ 55 ］ are the circuit board fixed screw, also is simultaneously control lamp line fixed screw, and ［ 52 ］ are circuit boards, and ［ 53 ］ are switch panel, and ［ 54 ］, ［ 56 ］ are the switch installing hole.
