Abstract

The utility model introduces a stepless regulation touch switch which is composed of a light modulating integrated circuit, a controllable silicon control circuit, a DC voltage stabilizing circuit, an indicating circuit and a sensing circuit. If the touch is temporary, the switch is in the on-off mode; if the touch time is slightly long, the switch is in the circulating regulation mode; when the user is satisfied and stops touching, the lamp brightness is memorized and kept until the next regulating alteration. The mode of wire connection is a single-wire ingress and egress system, and the wire just needs to be connected in series in a load loop.

Description

Touch dimmer switch

The utility model relates to a kind of mains switch, particularly a kind of dimmer switch that touches control mode.

Existing illuminating lamp soft-touch control is to show its position of the switch by a luminous tube, after staff touches, and the switch connection bulb power, after the certain hour time-delay, circuit automatically returns to off state, as the flash of light indication touch delay switch of CN207935U record.

The purpose of this utility model is a kind of utilization of design touch manner control circuit switch easily, has continuously adjustable within a certain period of time, the broad-spectrum mains switch of memory function and voltage swing.

This touch dimmer switch is realized above-mentioned purpose by following structure: it is made of casing and electronic circuit two parts, electronic circuit is made of sensing circuit, indicating circuit, direct current regulation circuit, SCR control circuit and light adjusting circuit, transducing signal output links to each other with the light adjusting circuit signal input part, direct current regulation circuit output termination light adjusting circuit power input, the light adjusting circuit signal output part connects the SCR control utmost point, and indicating circuit is connected across the two ends, loop.

The utlity model has suitable resistive load such as stepless dimmings such as incandescent lamp, electric furnace, temperature adjustment function, be fit to the stepless speed regulation of general electric fan too, the mode of connection is a single line turnover system, as long as be connected in the load circuit.In the SCR control circuit, select the thyristor of different size, can make and regulate tens of kilowatts of power up.This switch adopts of short duration touch manner control switch, and has memory function, brightness when the brightness of lamp keeps last time turn-offing when touching unlatching, the touch time, circuit was the stepless dimming operation when long slightly, and the brightness of lamp circulates from high to low and carries out, after the user is satisfied, stop to touch, switch is promptly remembered brightness and keep automatically, makes the user feel extremely convenient, also makes mains switch improve class simultaneously.

Accompanying drawing is the utility model embodiment:

Fig. 1 touches the dimmer switch electrical schematic diagram.

Fig. 4 shell side view

Among Fig. 1, constitute sensing circuit by sheet metal (7) and R6, R5, LED and R1 constitute indicating circuit, DW, D, C1, C2 constitute direct current regulation circuit, BCR and R3, R4 constitute the SCR control circuit, the LS7232 integrated circuit that U.S. Infineon Technologies Corp. produces and C3, C4 constitute light adjusting circuit, and X1, X2 are the terminals that are connected with AC network, and bulb string is connected in the loop.

Light adjusting circuit uses the integrated circuit LS7232 of U.S. Infineon Technologies Corp..It is right to work, and at first by its inner phase-locked loop the frequency of oscillation of internal oscillator is locked in mains frequency exactly, for the phase shift trigger impulse provides correct time.The generation of phase shifting angle is controlled by logical circuit, the particular moment in each cycle of interchange, send a trigger impulse, and in the output of 8 pin, remove to control the external silicon controlled angle of flow.When input 5 pin of LS7232 were low level, the phase shift range of its 3 pin output trigger impulse periodically started variation between 15 °～154 °, thereby the alternating voltage in the load is changed periodically automatically.When 5 pin became high level, circuit stopped to regulate, and phase shifting angle of its output trigger impulse is locked in this moment herein, thereby made alternating voltage in the load also be locked in the magnitude of voltage in this moment.

In the circuit, C1, C2, R2, DW, D constitute resistance-capacitance depressurization formula D.C. regulated power supply, use for LS7232, and this part also is the key problem in technology that D.C. regulated power supply is provided to control element as the switching mode product.C3 determines brightness, and C4 determines darkness.R5 is that touch sensitivity is regulated resistance.When touch time during less than 332 milliseconds, be the one open-one close operation, during greater than 332 bright seconds the light modulation operation, kind circulated a week in per 6 seconds.

Present embodiment adopts square moulding casing assembling.Two installation port lids (4) that are symmetrical in label (3) both sides are arranged on the panel (1), screw is covered, an indicator lamp hole (2) is arranged on the label (3), luminous tube is installed in the hole with the homochromy vinyl cover of round end.(5) be terminals, light adjusting circuit is inserted the illuminating lamp loop, (6) are bonnet.
