Description

The infrared remote control lighting switch

The utility model relates to electric switch, more specifically is meant a kind of infrared remote control lighting switch.

Development along with Infrared Ray Remote Control Technology, Infrared remote controller is along with various household electrical appliance enter family, all be equipped with Infrared remote controller as television set, video tape recorder, VCD, air-conditioning etc., bring convenience to users, say in a sense, the consumer has be unable to do without remote controller when using household electrical appliance, and the electric equipment products of not having the remote control growth requirement in incompatibility market.But inharmonicly with it be, Infrared remote controller is not widely used for common ligthing paraphernalia so far yet, that is to say, the common ligthing paraphernalia of control still is a hand switch at present, and this hand switch is inconvenience to some extent in the use, as, after with Infrared remote controller switch household electrical appliance, if during the switch lighting utensil, then must stand up to open or close again, obviously this can make the operator feel inconvenience.

For this reason, the purpose of this utility model provides a kind of infrared remote control lighting switch, and this lighting switch can open or close ligthing paraphernalia receiving the signal that the employed Infrared remote controller of existing household electrical appliance is sent.

To achieve these goals, the utility model adopts following technical scheme: this infrared remote control lighting switch comprises a housing, infrared receiving unit, infrared receiving unit places in the housing, it is characterized in that: comprise infrared reception amplifying circuit in the infrared receiving unit, single-shot trigger trigger, latch drive circuit, power circuit, infrared reception amplifying circuit carries out processing and amplifying to the infrared signal that is received, handle back output and be connected to single-shot trigger trigger, single-shot trigger trigger is made integer to the signal after amplifying and is handled, output after the process integer is handled is connected to latchs drive circuit, latching drive circuit counts and drives, power circuit provides operating voltage for above-mentioned each circuit, and its output is connected to infrared reception amplifying circuit respectively, single-shot trigger trigger and latch drive circuit.

The utility model mainly adopts by infrared reception amplifying circuit, single-shot trigger trigger, latchs the infrared remote control lighting switch that drive circuit, power circuit constitute, receive the infrared signal of Infrared remote controller emission of household electrical appliance when infrared remote control lighting switch after, this switch can be controlled opening or closing of ligthing paraphernalia, therefore, provide convenience for the operator.

Below in conjunction with drawings and Examples, the utility model is done one explains:

Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.

Fig. 2 is the circuit block diagram that the utility model adopted.

Fig. 3 is circuit theory diagrams of the present utility model.

See also shown in Figure 1, this infrared remote control lighting switch comprises a housing 3, infrared receiving unit 5, infrared receiving unit 5 places in the housing 3, one metal screen layer 4 also is set between housing 3 and infrared receiving unit 5, on housing 3, offer a window aperture, be equiped with filter part 2 on window aperture, after above-mentioned receiving unit 5, metal screen layer 4, filter part 2 were installed in the housing 3, its profile and size were as now commercially available common switch on wall size.

Please continue to consult Fig. 2, shown in Figure 3, comprise infrared reception amplifying circuit in the infrared receiving unit 5, single-shot trigger trigger, latch drive circuit, power circuit, infrared reception amplifying circuit carries out processing and amplifying to the infrared signal that is received, infrared reception amplifying circuit mainly comprises an infrared amplification chip IC 1, infrared receiving tube P1 and resistance R 1, R2, capacitor C 1, C2, C6, the model of IC1 is CX20106, meet infrared receiving tube P1 between the pin 1 of this chip and the ground, pin 8 connects the positive pole of power supply, pin 4 ground connection, the indirect regulation resistance R 2 of pin 5 and pin 8, the resistance of regulating resistance R 2 can make the frequency of IC1 internal pass band filter change, to be suitable for the carrier frequency of different remote, pin 7 is connected to single-shot trigger trigger as the output of infrared reception amplifying circuit, single-shot trigger trigger is made integer to the signal after amplifying and is handled, single-shot trigger trigger is by basic circuit chip IC2 in a period of time (model adopts NE555), resistance, resistance R 4, R5, capacitor C 3, LED 1 is formed, the pin 2 of time-base circuit NE555 is an input, pin 3 is an output, also is connected to an indicating circuit between output and the ground.Indicating circuit is made of resistance R 5, LED 1 serial connection, exports to after pin 3 outputs of chip IC 2 are handled the signal integer through diode D1 and latchs drive circuit.The purpose that single-shot trigger trigger is set is because infrared carrier signal waveform complexity, directly cause the instability of circuit easily as triggering signal, so must do shaping to the signal after amplifying handles, make it to change into a stable square-wave signal, overcome " shake " and provide a reliable trigger impulse, can make the big raising of global reliability of circuit like this through circuits for triggering.Trigger impulse is delivered to and is latched drive circuit; latching drive circuit comprises and latching and drive part; it is counted and drives; latch drive circuit and comprise ic chip 3; drive triode Q1; relay K 1; resistance R 6; ic chip 3 is a double D trigger; model is CD4013; its pin 14 connects positive source; pin 1 connects the base stage that drives triode Q1 as the output that latchs drive circuit by resistance R 6; pin 3 is for latching the input of drive circuit; triode Q1; relay K 1; resistance R 6 is a drive part; relay K 1 is connected between the collector electrode and positive source of triode Q1; at relay K 1 two ends and be connected to protection diode D2, the switch J of relay K 1 is serially connected with in the circuit of ligthing paraphernalia.Power circuit provides operating voltage for above-mentioned each circuit, its output is connected to infrared reception amplifying circuit, single-shot trigger trigger respectively and latchs drive circuit, power circuit adopts existing multiple power source, and voltage stabilizing is partly carried out voltage stabilizing (model is 7805) with voltage stabilizing didoe D3 and integrated package of pressure-stabilizing IC4.Said latch in the drive circuit drives between the input and ground of integrated package of pressure-stabilizing IC4 that triode Q1, relay K 1 be connected to power circuit, provide the drive part operating voltage by voltage stabilizing didoe D3, and the output of integrated package of pressure-stabilizing IC4 only offers other circuit, can reduce the load of integrated package of pressure-stabilizing IC4 like this, make the big reduction of its heat, make the utility model switch to use for a long time.For the utility model switch also can manually open or close, at the input (pin 2 of IC2) of said single-shot trigger trigger also by resistance R 3 and be connected to touch electrode P2.
