Abstract
The utility model belongs to a prompting device, which particularly a lamp switch which has both acoustic and optical prompt facilities. Two half-wave rectifiers with opposite rectifying polarities are connected in series between a static contact of the lamp switch and an output connection terminal of the switch, wherein, one rectifier is composed of a plurality of diodes which are connected in series. Two voltage division points provide operating voltage for a music chip and a light-emitting diode. The half-wave rectifier is connected with a filtering capacitor. A housing of the switch is fixed with a sounding device, and in the meanwhile when the switch connected with a lamp load is switched on, not only light is provided for users, but also musical sound and a prompt signal of the switching on of an indicating light can be provided for users, so that the waste of electric energy resulted from the forget of switching off the lamp can be avoided. The utility model has the advantages of simple structure, no power expenditure at ordinary times, no increased total power during use and reliable, effective and obvious prompting effect of sound and light.
Description
The utility model belongs to suggestion device, particularly relates to a kind of lamp switch with prompt facility.
The existing lamp switch that designs for economize on electricity, time delayed turn-off switch normally is applicable to that generally public occasion uses, for example the corridor lighting lamp.Yet providing gate light, Room lamp and kitchen, lavatory for oneself with occasions such as lamps, obviously the time delayed turn-off switch is used in inconvenience.Real life shows, above-mentionedly causes the situation of waste of energy to exist in a large number with the lamp occasion because of can not in time turning off the light.
The purpose of this utility model provides a kind of lamp switch with sound, light prompt facility, to satisfy actual needs.
Above-mentioned purpose is achieved by the following technical programs: the printed circuit board (PCB) 2 that cue circuit fixedly is housed on switch case 1, the composition of cue circuit is, by each diode back two half-wave rectifiers in parallel that are in series with anti-phase diode, one end and switch fixed contact join, the other end and switch output wiring terminal join, two dividing points of the half-wave rectifier that is connected in series by each diode are connected to the power input of Music Clip IC respectively, two dividing points also are connected to the light prompting branch road that filter capacitor C and current-limiting resistance R and LED light-emitting diode 4 are in series, the output of Music Clip IC is connected to the microphone device 3 that is fixed on the switch case, and switch case is provided with phonate hole 5 and the perforate of the dress light-emitting diode 4 that crouches.
Said cue circuit is that two ends are in parallel with reverse rectifier diode D6 after being in series by five forward rectifier diode D1-D5, the positive pole of the rectifier diode that is in series connects the switch fixed contact, and the negative pole of rectifier diode D1, D5 is connected to "+" "-" power input of Music Clip IC respectively;
Said microphone device 3 is piezoelectric ceramic pieces, also can be loud speaker.
Below with drawings and Examples explanation the utility model.
Among accompanying drawing 1 the utility model structural representation accompanying drawing 2 the utility model electrical schematic diagram figure: 1 switch case, 2 printed circuit board (PCB)s, 3 microphone devices, 4 light-emitting diodes, 5 phonate holes, 6 switch backguys.
Embodiment as shown in Figure 1, this lamp switch is a pulling switch, the printed circuit board (PCB) 2 and the microphone device 3 of cue circuit fixedly is equipped with in the bottom of switch case 1, the microphone device of present embodiment is selected piezoelectric ceramic piece for use, sound spreads out of from the set phonate hole 5 in switch case bottom, in 3 meters scopes, all can hear music tip sound, if need transaudient scope can select for use the sheet type miniature loudspeaker to get final product more greatly.Switch case is the dress light-emitting diode 4 that crouches in the perforate on the spiral cover.This lamp switch turn-on lamp sends music tip and the bright light prompting of light-emitting diode in the time of bright.Its operation principle is seen Fig. 2, and five diode D1-D5 conducting lamps of connecting when connecting the positive half cycle of switching AC voltage are bright, and diode D6 conducting lamp is bright during negative half period, but the i.e. lamp operate as normal controlled of switch.Meanwhile, alternating current positive pressure half cycle through being in series five diode halfwave rectifier and through filter capacitor C filtering, make Music Clip IC obtain dividing potential drop sum periodic duty near the direct-current working volts of 3V of diode D2-D5, LED light-emitting diode 4 is conducting simultaneously also, until turn-offing this switch.Can obtain synchronous sound, light prompting when visible light is bright, thereby effectively remind the user in time to turn off the light, avoid waste of electric energy.
The utility model equally also is suitable for the wall lamp switch.
The utlity model has simple in structure, not power consumption when not working, general power does not increase during work , sound, light are pointed out effective remarkable advantage reliable for effect.
Claims (3)
1. lamp switch, by switch case, moving, fixed contact, input, output wiring terminal and toggle mechanism are formed, it is characterized in that: the printed circuit board (PCB) that cue circuit fixedly is housed on switch case, cue circuit is to be joined by each diode series connection back two half-wave rectifier one ends and switch fixed contact in parallel with backward diode, the other end and switch output wiring terminal join, two dividing points of the half-wave rectifier that is connected in series by diode are connected to the power input of Music Clip respectively, two dividing points also are connected to the light prompting branch road that filter capacitor and current-limiting resistance and light-emitting diode are in series, the output of Music Clip is connected to the microphone device that is fixed on the switch case, and switch case is provided with phonate hole and the perforate of the dress light-emitting diode that crouches.
