Description

A Automatic Delay Putting Out Lights Unit of Light Instrument and Electric Instrument and Method Thereof}

The present invention relates to an automatic delay switching device and method for lighting and electric appliances, and in particular, a bypass circuit line is further added to a main switch or a luminaire for operating the lighting and electrical appliances, and the battery power is supplied at the time of delayed off. The present invention relates to an automatic delay switching device and method for lighting and electric appliances that enables delayed switching of lighting and electric appliances without a separate external power supply.

In general, the light switch is installed or mounted on the wall near the door, it is inconvenient because the interior is dark when moving to a certain position after turning off the lights (lights) to turn off the lights (lights) to the usual on / off.

In other words, if you try to go to bed after turning off the lights when you go to bed in a room equipped with a general light switch that does not have a delay function, you may feel uncomfortable to move to the sleeping area by avoiding obstacles while groping with your hands or feet. .

In addition, when going out or going out after the lights out, the moving copper wire is dark, so if you encounter obstacles or difficult to move, you may need help from the auxiliary lights, and the distance between the entrance and the switch is separated. This phenomenon is exacerbated.

In addition, even in the use of electrical equipment, such as a ventilator, the operation stops immediately when the switch is turned off, so there is a problem that the air inside the toilet is polluted if the switch is cut off immediately after using the toilet.

Of course, it is possible to install a timer or the like to delay off the lighting fixtures, but it is expensive and difficult to install the problem is inefficient, according to the situation that the lighting fixtures or electric appliances used in the home does not have a separate delay lamp itself.

In addition, the current state of delay lighting and the like has been adopted by a method of discharging a predetermined time using a capacitor or a relay which is delayed according to the capacity of a capacitor by using a capacitor as a control element. In addition, if the charge and discharge of the capacitor is frequently made, there is a problem in that it is difficult to use for a long time due to the limited lifetime of the product.

On the other hand, the applicant has proposed 'delay switching device and method of lighting equipment and electrical equipment' through 10-0836278.

The delay switching device of the present invention is largely an AC power supply unit 100, a luminaire or electric appliance 200, the main switching means 300, the switch wiring connection terminal 400, the diode bridge network 500 And the main switch on / off signal transmitting means 600, the power charging unit 700, the microcomputer 800, the delay switching unit 900 and the dip switch 1000.

Hereinafter will be described in more detail the configuration of the present invention.

The AC power supply unit 100 is a device for supplying AC power supplied from KEPCO to the home.

The lighting device or the electric device 200 is a device that one side is connected to the AC power supply is turned on or operated by the supply of AC power.

The main switching means 300 electrically connects the other side of the AC power supply and one side of the lighting device or the electric device to switch the output of the AC power supply to turn on or off the operation.

The diode bridge network 500 is formed by connecting four diodes in the form of a bridge, and does not operate when the main switching means 300 is turned on. The output signal of the means 300 is output, and when the delay switching signal is output, the switching between the AC power supply unit and the luminaire (or the electric appliance) is performed for a delay switching operation for a predetermined time. That is, the diode bridge network 500 detects the off of the main switching means, and simultaneously switches the AC power when the delay switching signal is output.

The main switch on-off signal transmitting means 600 is connected to an output terminal of the diode bridge network 500, and is composed of a resistor for a power supply branch, a zener diode and a smoothing capacitor, and converts the on / off signal of the main switching means into a diode. The input from the bridge network 500 is transferred to the microcomputer 800.

The power charging unit 700 is connected in parallel to the output terminal of the diode bridge network 500 and consists of a one-way power transmission diode, two Zener diodes for a constant voltage supply and a rechargeable battery AC supplied through the diode bridge network 500 The power is branched and charged, and power is always supplied to the microcomputer 800 to operate the microcomputer.

The microcomputer 800 performs a necessary operation by supplying power from the power charging unit 700, and is connected to the main switch on / off signal transmitting unit 600, the delay switching unit 900, and the dip switch 1000. When it is determined that the main switching means 300 is turned off by the output signal of the switch on / off signal transmitting means 600, the dip switch 1000 outputs the delay switching signal through the delay switching unit 900 for a specified time.

The dip switch 1000 is connected to the microcomputer to determine the delay switching time.

The delay switching unit 900 may include a first switch TR1 formed of a transistor, a second switch TR2 having a base connected to one end of the first switch, and a second end of the second switch and a gate terminal. It is connected to this diode bridge network, and the drain terminal is composed of a third switch (FET) connected to the ground terminal.

Accordingly, when the first switch TR1 is turned on according to the control signal of the microcomputer 800, the delay switching unit 900 activates the base terminal of the second switch TR2 to operate the second switch TR2. When the second switch TR2 is turned on, the gate terminal of the third switch FET is activated so that the third switch FET is operated so that the diode bridge network 500 is operated so that the AC power supplies the diode bridge network 500. Power is supplied to the lighting device (or electric equipment) through.

Looking at the operation of the present invention in more detail as follows.

First, the AC power supply unit 100 always provides AC power supplied from KEPCO to a lighting device or an electric device, and turns on and off one side line of the AC power supply unit 100 and the lighting device or the electric device 200. The switching means 300 are connected.

The AC power supply unit 100, the luminaire (or electric appliance) 200, and the main switching means 300 are commonly used in all luminaires or electric appliances 200, and belong to the general technology.

The present invention is connected in parallel to the AC power supply line connected to the main switching means 300 and the power supply line of the luminaire (or electric appliance) so that the AC power supply and the illumination in parallel as soon as the main switching means 300 is turned off. The appliance (or electric appliance) 200 is electrically connected to the device to be delayed by connecting a predetermined time.

To this end, in the present invention, the switch wiring connection terminal 400 is installed in parallel to the main switching means 300, and detecting the on / off of the main switching means 300 through two lines of the switch wiring connection terminal 400. In order to connect the diode bridge network 500 in which four diodes are connected in a bridge form.

Since the diode bridge network 500 is electrically connected to the third switch FET constituting the delay switching unit 900, the main switching means 300 is connected to the on state, so that the microcomputer 800 is delayed switching. If the operation signal is not output, the third switch FET is maintained in an off state, and thus is turned off, thereby disconnecting the bridge network 500, thereby preventing power transmission.

At this time, when the main switching means 300 is off, the power of the AC power supply unit 100 is instantaneously induced in the diode bridge network 500, and thus the power is diverted to the main switch on / off signal transmitting means 600, thereby maintaining the main power. The microcomputer 800 connected to the switch on-off signal transmitting means 600 recognizes the off of the main switching means 300.

Accordingly, the microcomputer 800 outputs a delay switching signal for a time set in the tip switch 1000. The microcomputer 800 turns on the first switch TR1 of the delay switching unit 900 and accordingly, the second switch TR2. When the third switch (FET) is turned on, the diode bridge network 500 is electrically contacted.

Then, the power of the AC power supply unit 100 is electrically connected to the luminaire (or electric appliance) 200 through the diode bridge network 500, and the luminaire (or electric appliance) 200 is not turned off continuously. Allow power to be supplied.

At this time, the electricity flowing through the diode bridge network 500 is connected in parallel to the power charging unit 700, the electricity is charged to the power charging unit 700 in a state where the diode bridge network 500 is electrically connected.

In addition, in the present invention, the diode bridge network 500 and the FET device as the third switching device are connected and operated. The reason why the FET device causes the switching operation is that the driving current (gate current) is almost the advantage of the FET. Since the power usage efficiency is lower than TR because it does not flow, and the voltage drop between drain sources is smaller than TR when handling the same power (less than half of TR as pure resistance), the power utilization rate is high. to be. Accordingly, in the present invention, the FET was selected as the third switching element.

After that, when the predetermined time is completed, the microcomputer 800 turns off the first switch TR1 constituting the delay switching unit 900, and accordingly, the second switch TR2 is turned off. ), The diode bridge network 500 is electrically disconnected so that the switching means for connecting the AC power supply 100 to the luminaire (or the electric appliance) 200 no longer exists. Accordingly, the lighting device (or electric device) is turned off or stops working when the time set by the dip switch is completed.

In addition, according to the present invention, the circuit elements of the present invention do not operate at all when the main switching means 300 is in an on state or the main switching means 300 in which the delay time is completed is off. Can be used for a long time.

That is, the circuit element of the present invention is operated only immediately after the main switching means 300 is turned off, thereby minimizing electrical operation.

The operation of the present invention is summarized in stages as follows.

Sensing on / off of the main switching means using a diode bridge network (S10);

If it is determined that the main switching means is off, the main switch on-off signal transmitting means outputs a main switch off signal to the microcomputer (S20);

Outputting, by the microcomputer, a control signal according to delay switching for a time applied from the tip switch according to the main switch off signal (S30);

In operation S40, the FET connected to one side of the diode bridge network is switched under the control of the microcomputer, so that the diode bridge network electrically connects the AC power supply unit and the lighting device (or the electric device) to be delayed switched for a predetermined time (S40).
