This proposal is divided into a lighting lamp circuit (hereinafter referred to as "flasher") and a signal generator circuit (hereinafter referred to as "signal generator") to install a flasher in the lighting fixture or box for lighting lighting and to generate a signal from here. Power distribution up to DC (eg DC9V) is to be supplied, but it is a tumbler switch in one switch box, and turns on immediately and turns off after 4 hours of switch, random time switch, 5 stage dimmers The present invention relates to an electronic non-contact quench switch for indoor lighting, which can be mounted in a four-hole circuit, in which a circuit is incorporated.

Conventionally, a switch for indoor lighting uses a tumbler switch, a push switch, a slide resistance type and a volume resistance type electronic switch, but structurally has mechanical abrasion and fatigue, resulting in a decrease in durability and a high failure rate. When moisture or dust penetrates inside, it does not exclude the failure caused by a short circuit. In addition, the wiring of all existing light switch uses the size of wire suitable for the rated voltage and current of the lamp. Therefore, it is pointed out that the defects that increase construction cost due to the increase of wire installation cost are indicated. Only three holes (three circuits) can be mounted, and the distribution voltage between the lamp and the switch is the same as the rated voltage of the lamp, so that the switch can be opened or closed with wet hands, the switch is operated from a wet floor, or the switch contacts In case of malfunction or failure, if you touch the wire by mistake during the overhaul without checking the power, it may cause an electric shock.In addition to the noise caused by the mechanical structure during the switch operation, spark phenomenon may occur due to overcurrent. Is generated and spark phenomenon by ignition of gas in hazardous place such as closed space This can cause a fire accident by ignition of gas in a hazardous place such as an enclosed space, and innumerable defects such as interference of watching and listening due to the inflow of radio noise caused by electronic devices such as TV audio. It is pointed out.

In order to solve the above-mentioned defects, this proposal electrically insulates the light load side and the switch side by using a photocoupler so that the voltage supplied to the load side does not flow into the switch side, and the switch side can operate the integrated circuit. Low voltage DC power is supplied to generate the lighting signal output. This lighting signal output is to be distributed by small-capacity wires such as control wires or indoor telephone wires, and four circuits can be mounted in one switch box. When described in detail as follows.

That is, the terminal of the switch triac (TA ₁₎ for (T ₂₎ and tri for the terminal (T ₃₎ is interposed, and the power supply (E) to the illumination load (L ₁₎ between the rectifier circuit (RE ₁₎ switch liquid In the connection between the terminal T ₁ and the terminal T ₃ of the TA ₁ to supply the resistor R ₁ , the crossover switch K, the capacitor C ₁ , and the rectifier diode RD.

And the signal output output from the signal generator 2 to be input to the photocoupler PC _{1 in the} burner 1 through the connector S ₁ , but not to the signal generator 2. 2) is composed of a flip-flop circuit 2A for generating a lighting signal and a binary ripple counter circuit 2B for generating a clock signal of the flip-flop circuit 2A. On the other hand the ever connected by mounting the signal generator (2) and the LED (LED _1), teotchi plate (TP ₁₎ in the switch box (SB) for for plate recognition light emitting diode (LED _1), teotchi plate (TP ₁₎ In addition to the tumbler switch signal generator 2, when the lights are turned off, the random time delay signal generator 3, the random time switch signal generator 4, and the five-step dimmer signal generator 5 are used for each purpose. of the signal output connector (S _{2), (3} S) (S ₄₎ through the respective guide points, each CPU (6) (7) (8), but ever inputted to each of the respective rectifier circuit (RE ₁ -RE ₄₎ At the same time, the common side of the output polarity is connected to the transmission line LN, and the mutual generators 2 and 5 are mounted in one switch box SB.

In the above description, the transmission line LN is a kind of wired remote control wiring, which is used as a control vinyl wire or an indoor telephone line, and in the switch box SB, in addition to the signal generators 2 and 5, the quench plate is used. Four-circuit circuits of (TP ₁ -TP ₂ ) and light emitting diodes (LED ₁ )-(LED ₄ ) are mounted.

When the light is turned off, the random time delay signal generator 3 receives the clock signal of the flip-flop circuit 2A from the multivibrator 3 for a predetermined time, and the output of the multivibrator 3A is a flip-flop circuit ( The lighting signal output of 2A) and the switching diodes SD ₁ and SD ₂ are connected in parallel to each other so as to be granulated in the firing machine 6.

In addition, the signal generator 4 for the arbitrary time switch is a multivibrator 3A, and is inputted by the time constant of the capacitor C ₂ and the low temperature R ₂ , so that the input of the firing unit 7 is performed. The signal generator 5 is composed of a decade counter 5A and a binary ripple counter 5B, and ZD is a zener diode for keeping constant power supply constant. The flip-flop circuit 2A is a J-K master slave flip-flop, the count circuit 2B is a binary ripple counter, and the multivibrator 3A is a precision monostable multivibrator.

In the figure, L ₂ , L ₃ , and L ₄ are lighting loads of each of the firing machines 6, 7, and 8, and each of the firing machines 6, 7, and 8 is composed of the firing machine 1. 9, 10, 11, and 12 are lighting lamp mounting boxes for mounting the arcs (1) (6) (7) (8) respectively. In addition, a resistor (R ₃ ) and a capacitor (C ₃ ) connected in parallel to the terminals (T ₁ ) (T ₂ ) of the triacs (TA ₁ )-(TA ₄ ) are for protecting each of the triacs, and the photocoupler (PC) ₁₎ for a photo triac switching current limit in the (PC ₁₎ - (a resistance (R ₄₎ is a photo coupler (PC ₁₎ connected to a resistor (R ₄₎ connected to the PC _4).

The effect of the present invention configured as described above is as follows.

First, the lighting load (L ₁ )-(L ₄ ) is respectively the triac (TA ₁ )-(TA ₄ ) terminal (T ₂ ) and the flasher (1) (6) (7) (8) It is connected by a conductor connected to the terminal (T ₃ ) of the rectifier circuit (RE ₁ )-(RE ₄ ), and the power supply (E) is connected to the terminal (T ₁ ) and the terminal of the triac (TA ₁ )-(TA ₄ ). T ₃ ) is supplied by connecting to the wire connected to the rectifier. (RE ₁ )-(RE ₄ ) Each (R ₁ ) is connected to only _one in case of 100V and two in case of 200V. Switch to the sensing over switch (K) so that. At this time, the DC power rectified from the rectifier circuits RE _{1 to} RE ₄ while the power E is supplied is connected to the signal generators 2 and 3 through the terminals (+) and (-) of the connector Co. 4) (5), and the signal inputs output from the signal generators (2) (3) (4) (5) are connected via the connectors (S ₁ )-(S ₄ ) to each of the firers (1) ( Triac to the (actual switching to firing a photo triac in the PC ₄₎ action - 6) (7) (8) each of the photo coupler (PC ₁₎ - (and input to the PC _4), photo coupler (PC ₁₎ The gate urge current of (TA ₁ )-(TA ₄ ) is introduced to allow electricity to flow, and thus power is supplied to each of the lighting loads L ₁ -L ₄ to be turned on. At this time, according to the magnitude of the signal flowing into the photocoupler (PC ₁ )-(PC ₄ ) and the light emission of the light emitting diode in (PC ₁ )-(PC ₄ ) is changed, the conduction power of the photo triac according to the changed light emission Is changed, and the conductance of the switching triacs TA _{1 to} TA ₄ is changed, and the voltage of the power supply is changed according to the conduction.

Due to the changed voltage, the incandescent lamp and the halogen lamp are changed to operate as a dimmer, and the power is supplied only for a predetermined time to operate as a time switch or a tumbler switch.

Hereinafter, the case-by-case examples will be described in detail.

When using the tumbler switch, when the user touches the quench plate (TP ₁ ), the signal is transmitted through a pulse circuit composed of a resistor (R ₅ ) and a capacitor (C ₄ ) through an insulation resistance (R) between the quench plate and the signal generator. Is inputted to the counter circuit 2B, and its output signal is inputted to the flip-flop circuit 2A as a clock signal, and is output in the opposite manner to the state before the clock signal was input.

That is, the signal output from the output terminal 15 to the flip-flop circuit 2A is input to the flasher 1 through the transmission line LN so that the load light L ₁ is turned on and the quench plate TP _1. ) When the output signal is changed and output to the output terminal 14, the lighting load L ₁ is turned off, and the light emitting diode LED ₁ for turning off the display and the watch plate is turned on. When the touch plate TP ₁ is contacted again, the output of the output terminal 14 is extinguished and the light emitting diode LED ₁ operates the flasher ₁ by the output signal of the extinguished high output terminal 15. The load light (L ₁ ) lights up.

On the other hand, when the touch plate TP ₁ is kept in contact, the ripple voltage is continuously input to the counter circuit 2B so that the output is generated at a predetermined time interval (for example, 0.5 seconds) to generate a clock signal to the flip-flop circuit 2A. In the case of incandescent lamps or halogen lamps in the load lighting (L ₁ ), the lights are turned off and on at 0.5 second intervals.

Secondly, when it is used as a switch for a random time delay when extinguished, it is used as a tumbler switch and a random time (for example, 10 seconds) timer is added. The clock signal is supplied to the flip-flop circuit 2A using a multivibrator ( The output of 3A) is connected in parallel to the lighting signal output of the terminal 1 of the flip-flop circuit 2a and the switching diodes SD ₁ (SD ₂ ). or a light-on state after the teotchi plate (TP ₂₎ to the light-off of the output input 10 seconds of the on-signal output is extinguished but multivibrator (3A) of the flip-flop circuit (2A) when there is some sort of trouble, the extinction contact It stays lit for 10 seconds.

In the above, the time can be arbitrarily determined, and the adjustment thereof is determined by the time constant in the capacitor C ₁ and the resistor R ₂ . In the above description, since the operation of the flip-flop circuit 2A is performed at the rising of the clock signal, when the flip-flop circuit 2A is operated at the output initial state for 10 seconds of the multivibrator 3A, the touch plate TP ₂ is contacted when the lamp is turned off. The lighting signal output of the flip-flop circuit 2A is immediately extinguished.

The resistor R _{7 on} the clock signal input side of the flip-flop circuit 2A is for sending the output of the multivibrator 3A to the nearly full capacity detector 6 when the lamp is turned off.

Third, in the case of using the arbitrary time switch, when entering the terminal 8 of the multivibrator 3A, a pulse is output from the terminal 10, and the width of this pulse is converted into a capacitor (between the terminal 15 and the terminal 14). Since the pulse having the width set by the product of the resistor R ₈ connected between the C ₆ ) and the terminal 11 is input to the interrogator 7, the load illumination is performed only for the time corresponding to the pulse width. (L ₃ ) is lit. If the volume resistance (R _8), for example have a 8MΩ set 176 seconds, when the teotchi plate (TP ₃₎ to jeopchuk will be 176 seconds jeomdong, if when the light again contact the teotchi plate (TP _3), wherein from You can keep 176 seconds on again. Since the pulse width in the above can be arbitrarily set from ㎲, it can be used as a clock signal generator to replace the binary ripple counter 2B.

Fourth, when used as a switch for a five-stage dimmer, the 10 decode outputs of the decade counter 5A are transformed into 5 decode outputs. That is, a terminal 3 (2) (4) (7) for taking pull the output in the order of 10 terminal 3 side load one trillion people (L ₄₎ off when a light emitting diode (LED ₄₎ light signal of step 5 The outputs of terminals 2, 4, and 7 are appropriately connected to resistors R, and the outputs are adjusted to input to the flasher 8 to set the illuminance of the load light L ₄ differently for each step. Then, common connection is made with the switching diode SD.

In addition, when the output of the terminal 10 is connected in common with the regulated output of the terminals 2, 4, and 7 through the switching diode SD without connecting a resistor, the output of the terminal 10 is connected to the quench plate ( Each time TP ₄ is contacted, the operations of steps 0, 1, ₂ , 3 and ₄ are repeated. For example, in step 0, the load light (L ₄ ) is turned off, the light emitting diode (LED ₄ ) is emitted to inform the off state and the position of the watch plate (TP ₄ ), the first stage is 25% light, the second stage is 50% For example, level 3 may be 75% and level 4 may be 100% illuminance.

If the watch plate (TP ₄ ) is in continuous contact, for example, repeat the five-step operation at intervals of about 0.5 seconds.If the contact is released at the required step, the illuminance of the step is maintained, and if the contact is made again, the next step is changed. Illumination will be maintained.

Since this circuit is a contactless circuit, it is completely free from mechanical abrasion and fatigue. Unlike conventional wiring, new wiring, a kind of wired remote operation that supplies power from the firing to the signal generator to a DC power source, is a new wiring. At the same time, the operating voltage and current of the signal signal is extremely small, but the installation line is used as a control vinyl cable or a vinyl cable for bathroom calls in consideration of workability during installation. Economical and safe construction can be carried out by making common connection between the same polarity output from the direct currents, and by mounting four circuits in one switch box and separating them into a flasher and a signal generator. Significant savings in boxes, conduits and wires, as well as opening and closing the switch with wet hands Increase the safety by completely eliminating the case of causing the transfer, the firing signal emits the diode of the photocoupler, the emitted light emits the diode of the photocoupler, the emitted light is the secondary side of the photocoupler It fires the phototriac, and the firing of the switch triac by the firing of the phototriac, that is, the method of electrically smooth operation, has no spark phenomenon, and there is no propagation noise. There is no accident of fire or explosion due to ignition, and it is a useful and practical design that does not adversely affect other electronic devices.
