Description

Touching light adjusting switch

The utility model relates to a kind of appliance switch, particularly a kind of touch stepless dimming switch that is used for incandescent lamp.

At present, the touch lamp dimmer of selling on the market, and disclosed contact witch kind is a lot of on the patent documentation, function is different.But shortcoming such as complex structure, functional reliability are poor, function singleness that ubiquity.Particularly be not suitable for constituting various universal switches.

The purpose of this utility model provides a kind of touch stepless dimming switch of controlling incandescent light source.It is simple in structure, and volume is little, has memory function, can constitute all kinds of universal switches.

The utility model is achieved in that it comprises switch case and two parts of circuit, it is characterized in that circuit part is made of power circuit and main circuit, the input of power circuit and civil power join, and it exports termination main circuit, for main circuit provides direct-current working volts, main circuit mainly is made of integrated circuit (IC) (LS7232) and bidirectional triode thyristor, bidirectional triode thyristor is series in the incandescent lamp current supply circuit, the silicon controlled control utmost point links to each other with the pulse output end of IC, and the input of integrated circuit (IC) is connected in touch trigger board; Switch case is made of panel and back cover, and circuit board is placed in one.

Dimmer switch of the present utility model is serially connected with in the incandescent lamp current supply circuit, when human body touch triggers input, the input of the voltage signal input ic IC of human body sensing, make the pulse signal of the output generation different frequency of integrated circuit, and then the control silicon controlled angle of flow, finally reach the purpose of controlling lamplight brightness.

The utility model is simple in structure according to having, reliable operation, and volume is easy to constitute multiple universal switch for a short time.

Further describe the utility model below in conjunction with drawings and Examples.

Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.

Fig. 2 is the shape assumption diagram of a kind of embodiment of the utility model.

In the embodiment shown in fig. 1, dimmer switch (part in the dotted line) is serially connected with in the incandescent lamp RL current supply circuit by contact.In the dimmer switch circuit part, power circuit is made of voltage stabilizing didoe D1, resistance R 1 and capacitor C 1 series connection, and its output terminals A and B are as the working power of circuit, and the B point is the reference ground of circuit.Main circuit is that core constitutes with extensive PMOS integrated circuit (IC) (LS7232) and bidirectional triode thyristor BCR, the input 5 of integrated circuit (IC) links to each other with touch trigger board ZM through resistance R 2, R3, the output 8 of integrated circuit (IC) links to each other with the control utmost point G of controllable silicon BCR via resistance R 5, peripheral components R4, the C3 of integrated circuit (IC), C4 make integrated circuit (IC) constitute controlled pulse signal generator, wherein R4 is connected between 5 ends of A end and IC, capacitor C 3 and C4 be connected to respectively A point and integrated circuit (IC) 3 and 4 between.Join with the A point after 1, the 2 end disconnectings of integrated circuit (IC), 4 of IC links to each other with the B point through resistance R 6.The two poles of the earth T1 of controllable silicon BCR and T2 are connected to A and B point respectively, promptly are serially connected with in the current supply circuit of incandescent lamp RL.

The course of work of the present utility model is such, and after in the dimmer switch place in circuit, because the trigger end 5 of IC does not have input signal, the IC output 8 of not working does not have output signal yet, and controllable silicon BCR ends, and lamp RL does not work.When human body contact trigger board ZM, the voltage signal of human body sensing triggers the input 5 of IC, and the phase-locked loop circuit of IC inside is followed the tracks of mains frequency, the internal oscillator frequency is locked on this frequency accurately, and makes phase shifter can export phase-shift pulse.Phase-shift circuit is subjected to the control of logical circuit, so can accurate timing ground output trigger impulse in every half period of alternating current.Trigger impulse again through numeral comparison and amplification after output 8 outputs drive controllable silicon BCR and finally reach purposes such as light modulation, switch.

Because dimmer switch circuit structure of the present utility model and selected device parameters determine that power connection electric light RL does not work, when time of touch trigger board ZM during less than 0.4 second, lamp is promptly lighted (the brightest); Touching (less than 0.4 second) lamp once more goes out.This is a switching function.If according to motionless, then lamp will be gradually changed to the most secretly by the brightest greater than 0.4 second the touch time, taper to the brightlyest again by the most secretly, change so repeatedly.When changing to suitable brightness, hand leaves trigger board ZM, and lamp will be stabilized in this brightness illumination.Here it is dimming function.Only otherwise have a power failure when turning on light once more, light this brightness illumination automatically, this is memory function just.

In order to ensure the safety of circuit, in the circuit of the present utility model protective tube FUSE can be set, it is series between live wire and the A point.The utility model also can increase the position of display circuit with indicator cock, and it is by light-emitting diode D2, and capacitor C 2 is formed, the positive pole of capacitor C 2 connects the A point, negative pole connects 6,7 ends of IC, and the positive pole of light-emitting diode D2 and the negative pole of C2 join, and the common port of the negative pole of D2 and resistance R 1 and capacitor C 1 joins.When switch was in wait state, IC did not work, and electric current stream C2, D2, R1 and C1 make light-emitting diode D2 send faint light.

Because circuit volume of the present utility model is little, in the regular tap of can packing into, Fig. 2 is exactly a kind of embodiment of wall type flush type switch.The overall dimension of panel 1 and back cover 5 should conform to the GB requirement of common wall formula flush type switch among the figure.Circuit board 4 is loaded in the back cover by mounting screw 6.Power-line terminal 7 passes back cover and is exposed on the external.Lead 9 connects the annular trigger board 2 of panel central authorities and the trigger end of circuit.Trigger board 2 is at panel surface, and luminous tube 8 is adorned at the center of annular slab 2.Through hole 3 on the panel is the installing hole of switch.Therefore, wall type flush type switch that the utility model constitutes and regular tap are installed as broad as long, and it is convenient completely really to use.
