At this time, the data is a start bit, binary 1 or binary 0.

The first zero voltage detector detects a first zero voltage point, which is a point in time when the voltage of the AC power becomes zero voltage, and outputs a first zero voltage point signal to the first controller 250.

The first controller receives the first zero voltage point signal from the first zero voltage detector, receives the data packet through the communication unit, and applies the data packet to the first zero voltage point, respectively.

In this case, the first control unit may store a first switching signal that is switched from the off state to the on state, a second switching signal that remains on, and a third switching signal converted from the on state to the off state in advance.

The first zero voltage detector detects the first zero voltage point, and when the first zero voltage point is detected at the start of communication, applies a switching signal matched to the start bit to the switching unit, and then transmits each time the first zero voltage point is detected. The switching signal matching the bit value of the target data packet is sequentially applied to the switching unit.

In this case, a first switching signal or a third switching signal is matched to the start bit, and two remaining switching signals are randomly matched to the binary 1 bit and the binary 0 bit except for the switching signal matched to the start bit.

In one case, the modified AC power generated by cutting off the AC power is output.

The power supply unit 310 rectifies the AC power supply 20 to supply power required for the operation of the second control unit 320 and the second zero voltage detection unit 330 and the lighting of the LEDs.

The second zero voltage detector 330 receives the modified AC power output from the switching unit, detects a second zero voltage point at which the voltage of the modified AC power becomes a zero voltage, and outputs a second zero voltage point signal to the second controller 320. )

The second control unit 320 sequentially receives the second zero voltage point signal and turns off the second zero voltage point signal during the half cycle based on the time point whenever the second zero voltage point of the modified AC power source is detected. In the case of maintaining the state, the case in which the case of maintaining the off state in the off state is determined. Accordingly, when the second zero voltage point signal is kept in the off state from the off state, the second zero voltage point signal is read with a bit value that is previously matched to the third switching signal. In the case of reading the bit value and maintaining the off state in the on state, the read data packet is read out with the bit value matched to the first switching signal in advance, and the received data packet is sequentially outputted. In this case, the second controller 320 stores the generated received data packet.

In addition, the data communication method and the communication device using the phase angle control of the AC power source of the present invention, the LED lighting controller and the phase angle control communication receiver is configured in a 1: 1 ratio, and interlocked one by one, the LED lighting controller is a transmission target to the corresponding communication receiver. Data can be communicated by transmitting a data packet, and a plurality of communication receivers are configured in one LED lighting controller so that the LED lighting controller transmits the unique code of the corresponding communication receiver and the data packet to be transmitted to each communication receiver. You can also communicate.

Phase angle control communication receiver 350 is included in the interior of the LED lighting power supply 300 or a separate product including a control signal output unit 356 for controlling the output of the conventional general LED lighting power supply 300 Can be configured.

That is, the present invention uses a phase angle control communication receiver 350 to control the conventional power supply that can not analyze the phase angle control communication signal, the phase angle control communication receiver 350 is a control signal output unit 356 It further includes.

At this time, the second controller reads the second zero voltage point signal received from the second zero voltage detector and outputs the generated data packet to the control signal output unit.

The control signal output unit 356 outputs a 0-10V output or PWM signal that can be recognized by a conventional power supply according to a received data packet input to the second control unit 354.

The LED lighting power supply receives the received data packet from the second controller, and supplies power to the LED module based on a control value corresponding to the received data packet.

Hereinafter, the operation of the embodiment of the LED lighting control device and method using the phase angle control communication of the present invention AC power will be described in detail.

First, the LED lighting controller 200 receives an external data source and a transmission target data packet indicating a brightness signal value consisting of a binary 1 bit and a binary 0 bit from the outside.

Next, the first zero voltage point detector in the LED lighting controller 200 receives the AC power source 20 and detects the first zero voltage point of the input AC power source 20.

Next, the first control signal 250 in the off state is turned on, the second switching signal is maintained in the on state, and the third switching signal is turned in the off state from the first control unit 250 in the LED lighting controller 200. Are randomly pre-matched to the start bit, the binary 1 bit, and the binary 0 bit, respectively, and the first zero voltage detector 230 detects the first zero voltage point and starts when the first zero voltage point is detected at the start of communication. The switching signal matched to the bit is applied to the switching unit 240, and then, each time the first zero voltage point is detected, the corresponding switching signal matching the bit value constituting the data packet to be transmitted is sequentially transmitted to the switching unit 240. Is authorized.

Next, the switching unit 240 in the LED lighting controller 200 receives the AC power source 20 and receives the first to third switching signals from the first control unit 250 to perform the first switching. When the signal to the third switching signal is in the on state, the AC power source 20 is passed, and in the off state, the AC power source 20 is cut off to generate a modified AC power source.

Next, the second zero voltage detector 330 in the phase angle control communication receiver receives the modified AC power output from the switching unit 240, sequentially detects the second zero voltage point, and transmits the same to the second controller 320. do.

Next, the second control unit 320 in the communication receiver sequentially receives the second zero voltage point, and whenever the second zero voltage point is detected, the second zero voltage point signal during the half cycle is turned off based on the time point. In the case of maintaining the ON state, the read value is read with the bit value previously matched to the third switching signal. If the state is maintained continuously, the read value is read as the bit value previously matched to the second switching signal. In the case of maintaining the state, a read data packet obtained by sequentially reading the bit values matched with the first switching signal in advance is outputted.

In this case, whenever the second zero voltage point is detected, the second controller 320 determines the second zero voltage point signal during the half cycle based on the time point, and the second zero voltage point signal is a signal corresponding to the start bit. From that point on, create a receive data packet.

Then, the reception data packet is stored in the storage unit 310 in the communication receiver.

In this case, the communication receiver may not store the received data packet.

Then, the LED lighting power supply receives the received data packet from the second controller, and supplies power to the LED module based on the brightness signal value corresponding to the received data packet.

The present invention receives the data through the above process to control the brightness of the LED light.

3 is an LED lighting controller circuit diagram of an LED lighting control apparatus and method using phase angle control communication of an AC power supply according to a preferred embodiment of the present invention.

First, the first zero voltage detector 230 will be described.

The general AC power supply 20 changes in magnitude and direction of voltage at a period of 50 or 60 Hz. The applied AC power supply 20 drops to a voltage recognizable in the circuit through the resistance distribution circuits R1, R2, and R3. The capacitor C1 connected to the portions of the bridge circuits D1, D2, D3, and D4 is charged by the voltage that changes with time, and is discharged through D5 when the voltage is lowered. The photocoupler OP2 is operated by the voltage charged in C1, and the low signal insulated by the zero voltage point signal input is input. When the voltage of the AC power source 20 reaches zero voltage according to the cycle, C1 is discharged to stop the operation of the photocoupler OP2 and the high signal insulated to the zero voltage point signal input terminal is input. Since the AC power source 20 generates two zero voltages in one cycle, the zero voltage point signal is generated at twice the frequency of the AC power source 20 frequency.

Since the circuit principle of the zero voltage detection unit is commonly used, a detailed description thereof will be omitted.

The switching unit 240 includes a first FET Q1, a second FET Q2, a photo coupler OP1, a zener diode, and a capacitor.

The first FET Q1 is an N-channel transistor. The drain terminal is electrically connected to the AC power source, the source terminal is electrically connected to the first ground terminal, and the gate terminal is electrically connected to the first node.

The second FET Q2 is an N-channel transistor, a source terminal of which is electrically connected to the first ground terminal, a gate terminal of which is electrically connected to the first node, and a modified AC power source is output to a drain terminal.

The photocoupler OP1 has a first end electrically connected to a first resistor connected to a first DC power supply Vcc, a second end electrically connected to a switching signal output end of the first controller, and a third end. Is electrically connected to a second resistor connected to a second DC power supply (Vdd), and the fourth stage is electrically connected to the second ground terminal, and when current flows from the first stage to the second stage, the third stage to the fourth stage Current is conducted.

The zener diode is electrically connected between the first node and the second ground terminal.

A capacitor is also electrically connected between the first node and the second ground terminal.

In addition, the first to third switching signals output from the switching signal output terminal of the first control unit 250, the voltage level of the on state is the same as the size (eg 3.3V) of the first DC power supply (Vcc) The off-state voltage magnitude of the first to third switching signals will be nearly 0 volts as a low voltage.

That is, if the voltage across the switching signal output terminal of the first control unit 250 is the same as the Vcc voltage of the first DC power supply, there is no voltage difference between the first and second terminals of the photocoupler, so that no current flows. Since no current flows between the third and fourth stages of the second node, the first node receives a voltage at which the second DC power supply Vdd is divided at a constant rate. Therefore, in this case, the voltage applied to the first node is higher than the voltage of the first ground terminal so that the first FET flows current from the drain to the source, and the second FET flows current from the source to the drain. As a result, the input AC power passes through the drain terminal of the second FET as it is.

If the voltage applied to the switching signal output terminal of the first control unit is the low voltage described above, a voltage difference is generated between the first and second ends of the photocoupler, so that a current flows. Accordingly, the current is also applied between the third and fourth ends of the photocoupler. As a result, the voltage of the third terminal drops to the magnitude of the voltage of the second ground terminal, and thus the voltage of the first node also falls to a voltage similar to that of the second ground terminal. Therefore, in this case, the voltage applied to the first node is equal to the voltage of the first ground terminal, and thus the first node voltage applied to the gate terminals of the first FET and the second FET is equal to the first ground terminal. In both the first FET and the second FET, no current flows, and eventually the AC power input is interrupted.

The phase angle control operates on the basis of the first zero voltage point signal, and maintains the phase angle control circuit in the ON state until the next zero voltage point signal input based on the first zero voltage point signal in a period where the phase angle is not controlled. .

During the period for controlling the leading edge, the phase angle control circuit is kept OFF for the phase angle control time based on the zero voltage point signal, and the phase angle control circuit is kept ON until the next zero voltage point signal is input.

When the trailing edge is controlled, the phase angle control circuit is turned ON during the trailing edge control delay based on the zero voltage point signal, and the phase angle control circuit is kept OFF during the phase angle control time.

According to the present invention, three combinations of a leading edge control waveform, a trailing edge control waveform, and a waveform having no phase angle control are generated. Therefore, the starting point of the data can be displayed in addition to the case of representing the data in response to the binary data. By indicating the start point of the data by using the start signal by the start bit, it is easy to implement general serial communication configured to facilitate data communication.

4 is a view showing a waveform generated by the LED lighting controller of the LED lighting control device and method using the phase angle control communication of the AC power according to an embodiment of the present invention, Figure 5 is a preferred embodiment of the present invention Figure 1 shows the waveforms read by the phase angle control communication receiver of the LED lighting control device and method using the phase angle control communication of the AC power.

4 and 5, first, the first control unit 250 stores the first to third switching signals, and the first to third switching signals are data input through the communication unit to an AC power source. In each of the switching signals corresponding to the start bit, binary 1 or 0 by applying the start bit, binary 1 or 0, the corresponding switching signal is applied to the switching unit according to the input data.

The first switching signal is a signal that is turned off and then turned on, the second switching signal is a signal that is continuously kept on, and the third switching signal is a signal that is turned from an on state to an off state.

At this time, the first switching signal is a state in which the switching signal is turned off only during the cut section by cutting the phase of the start portion based on the first zero voltage point of the AC power supply, and is turned on again from the uncut section. Waveform.

Since the second switching signal has no phase change with respect to the first zero voltage point of the AC power source, the switching signal is continuously turned on.

Since the switching signal is off only during the section cut by cutting the phase of the end portion based on the first zero voltage point of the AC power source, the third switching signal is turned on until the section is cut from the first zero voltage point. It is turned off in the section, and it is a trailing edge control waveform.

In the present invention, the LED lighting is turned on, off, brightness, color temperature is adjusted.

When the AC power source 20 is input to the LED lighting controller, the first zero voltage point of the AC power source detected by the first zero voltage detector 230 is input to the first control unit 250.

In this case, the first control unit 250 stores a first switching signal that is switched from an off state to an on state, a second switching signal that is maintained in an on state, and a third switching signal that is switched from an on state to an off state. Each of the switching signal, the second switching signal, and the third switching signal is set to match the start bit or binary one or binary zero, respectively.

For example, if it is assumed that binary 1 matches the first switching signal, binary 0 matches the second switching signal, and start bit matches the third switching signal, the first control unit 250 binds to the communication unit. When 1 is input, the first switching signal corresponding to the binary number 1 is output to the switching unit 240.

According to the first switching signal, the switching unit cuts off the AC power in the off state, passes the AC power in the on state, and transmits the alternating AC power generated by applying binary 1 to the AC power. )

The second zero voltage detector in the phase angle control communication receiver 350 detects the second zero voltage point of the modified AC power supply, and transmits the second zero voltage point signal to the second control unit.

In this case, a half period to be determined based on the second zero voltage point is specified in advance in the second controller.

For example, when the second control unit is designated to determine the half cycle of the modified AC power as a reference, when the modified AC power is input, the second control unit detects the second zero voltage point and ends the half cycle based on the second zero voltage point. To judge.

That is, the second control unit reads the on-off state whenever the modified AC power is input and the second zero voltage point signal is detected, and reads the on-off state at the end of the half cycle to turn on from the on state to the off state or the on-off state. It detects whether it stays in the off state or off and derives each received data packet accordingly.

In addition, the second controller 320 operates only when a switching signal matched with a start bit is input based on the second zero voltage point of the modified AC power source. This is to prevent unnecessary operation balance caused by noise.

For example, in the modified AC power source, when the second zero voltage point signal is turned on from the off state based on the second zero voltage point, the modified AC power source is a data start point.

6 is a view showing an embodiment of a modified AC power output to the phase angle control communication receiver of the LED lighting control device and method using the phase angle control communication of the AC power according to an embodiment of the present invention.

Hereinafter, AC power is input to the LED lighting controller and data packet 10100101 is input from an external terminal. The first control signal and the third switching signal are matched to binary 1, and the second switching signal is matched to binary 0. It is set so that the second control section is set to read a half cycle period based on the second zero voltage point will be described as an example.

 Referring to FIG. 6, the second control unit recognizes the start bit S as a start, wherein the start bit is switched from the on state to the off state or the second zero voltage point signal for half a period based on the second zero voltage point. 2 The zero voltage point signal is matched with a switching signal that is switched from an off state to an on state. That is, the start bit corresponds to the trailing edge control waveform or the leading edge control waveform.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the off state to the on state, the bit value binary 1 matching the first switching signal is detected.

Then, in the case where the second zero voltage point signal during the half period with respect to the second zero voltage point remains off, a bit value binary 0 matched with the second switching signal is detected.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the off state to the on state, the bit value binary 1 matching the first switching signal is detected.

Then, in the case where the second zero voltage point signal during the half period with respect to the second zero voltage point remains off, a bit value binary 0 matched with the second switching signal is detected. Then binary 0 is also the bit value from the same process.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the on state to the off state, the bit value binary 1 matching the third switching signal is detected.

Then, in the case where the second zero voltage point signal during the half period with respect to the second zero voltage point remains off, a bit value binary 0 matched with the second switching signal is detected.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the on state to the off state, the bit value binary 1 matching the third switching signal is detected.

As described above, the binary number 1 is a bit value matched with the first switching signal or the third switching signal, and the second zero voltage point signal for a half period based on the second zero voltage point is switched from the on state to the off state or the on state from the off state. It is output when switched to. The binary zero is matched with the second switching signal and output when the second zero voltage point signal for half a period based on the second zero voltage point remains off.

That is, the start bit corresponds to the leading edge or trailing edge control waveform, and the data to be transmitted is converted into binary so that the remaining phase angle control waveform corresponds to binary 1 or binary 0, and the phase angle is not adjusted. The waveform corresponds to the complementary number (01011010) of the binary number 10100101 value of the waveform whose phase angle is adjusted, and is sequentially supplied, thereby serially transmitting the received data packet to the LED illumination 500.

The LED lighting power supply receives the received data packet 10100101 read by the second controller and supplies power to the LED module based on a control value corresponding to the received data packet. For example, assuming that the control value is brightness control, power of LED lighting brightness corresponding to the received data packet 10100101 is supplied to the LED module.
