[0033] In existing technologies, the control device in a lighting control system is typically directly connected to the power source via a power conversion device. Furthermore, the power supply for the lighting fixtures also requires a corresponding power conversion device to convert the external power supply into a suitable power source for the fixtures. This results in a large number of power conversion devices in the lighting control system. In addition, the direct connection of the control device to the power source via a power conversion device can easily lead to safety issues such as electrical leakage.

[0034] Therefore, refer to Figures 1 to 8 This utility model proposes a lighting control circuit, which includes:

[0035] Main control circuit 10;

[0036] A drive power supply circuit 20 includes a power input terminal, a controlled terminal, and a power output terminal. The power input terminal of the drive power supply circuit 20 is electrically connected to an external power source, and the controlled terminal of the drive power supply circuit 20 is electrically connected to the main control circuit 10. The drive power supply circuit 20 is used to receive drive control signals output by the main control circuit 10 and adjust the output current of the power output terminal.

[0037] The light-emitting diode circuit 30 has its first terminal electrically connected to the first terminal of the power output terminal of the driving power supply circuit 20 and the first terminal of the power supply terminal of the main control circuit 10, respectively. The second terminal of the light-emitting diode circuit 30 is electrically connected to the second terminal of the power output terminal of the driving power supply circuit 20 and the second terminal of the power supply terminal of the main control circuit 10, respectively. The light-emitting diode circuit 30 is used to receive the output current of the power output terminal and generate light of corresponding brightness.

[0038] In this embodiment, the main control circuit 10 can be implemented using PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), SOC (System On Chip), etc.

[0039] In this embodiment, the driving power supply circuit 20 can be implemented using a combination of a voltage conversion circuit, a driving circuit, and a communication transceiver circuit 23. The controlled terminal of the driving power supply circuit 20 is electrically connected to the main control circuit 10 to receive the driving control signal output by the main control circuit 10, thereby adjusting the output current at the power output terminal. It is understood that the external power supply connected to the power input terminal of the driving power supply circuit 20 is AC, while the voltage required by the LED circuit 30 and the main control circuit 10 is DC. Therefore, the driving power supply circuit 20 includes a rectifier circuit to convert the AC input to the power input terminal of the driving power supply circuit 20 into DC and output it. Furthermore, while the driving power supply circuit 20 converts the AC input from the external power supply into the corresponding DC, the voltage of this DC does not meet the voltage requirements of the LED circuit 30 and the main control circuit 10. Therefore, the driving power supply circuit 20 also needs to be equipped with a corresponding DC / DC voltage conversion circuit to meet the voltage requirements of the LED circuit 30 and the main control circuit 10. In addition, the drive power supply circuit 20 also needs to receive the drive control signal output by the main control circuit 10 to adjust the output current at the power output terminal. Therefore, the drive power supply circuit 20 also needs to be equipped with a communication transceiver circuit 23, a corresponding power control circuit 22, and a drive circuit to achieve stable regulation of the output current.

[0040] Optionally, the driving power supply circuit 20 includes a voltage regulator circuit 21 and a power control circuit 22. The input terminal of the voltage regulator circuit 21 is electrically connected to the power output terminal of the driving power supply circuit 20 and the first terminal of the light-emitting diode circuit 30. The output terminal of the voltage regulator circuit 21 is electrically connected to the power supply terminal of the power control circuit 22. The voltage regulator circuit 21 is used to regulate the voltage output from the power output terminal of the driving power supply circuit 20 before outputting it.

[0041] In this embodiment, the power control circuit 22 can be implemented using a corresponding control chip to receive drive control signals and output corresponding control signals to the drive circuit. Specifically, an STC8G1K08A chip can be used. The voltage regulator circuit 21 can be implemented using a linear voltage regulator circuit, a switching mode power supply circuit, a clamping circuit, etc. Specifically, a precision adjustable voltage regulator based on a current-regulated reference, such as the CJ431, can be used. The CJ431 dynamically adjusts the output voltage by comparing the external input voltage with an internal reference voltage (typically 2.5V), thereby stabilizing the output voltage and providing a stable power supply voltage for the power control circuit 22. When the input voltage is higher than the reference voltage, the CJ431 outputs a larger current, causing the load voltage to decrease; conversely, when the input voltage is lower than the reference voltage, the CJ431 outputs a smaller current, causing the load voltage to increase.

[0042] Optionally, the drive power supply circuit 20 further includes a communication transceiver circuit 23, the first end of which is electrically connected to the power control circuit 22, and the second end of which is electrically connected to the main control circuit 10; the communication transceiver circuit 23 is used for receiving and transmitting communication signals.

[0043] In this embodiment, the communication transceiver circuit 23 can be implemented using an RS485 communication transceiver circuit 23, an RS232 communication transceiver circuit 23, or the like. The two ends of the communication transceiver circuit 23 are electrically connected to the power control circuit 22 and the main control circuit 10 of the drive power supply circuit 20, thereby enabling signal communication between the power control circuit 22 and the main control circuit 10. Specifically, the communication transceiver circuit 23 can be implemented using a CA-IF4805HS full-duplex transceiver and corresponding peripheral circuits.

[0044] Optionally, the drive power supply circuit 20 includes a first voltage conversion circuit 24, the input terminal of the first voltage conversion circuit 24 being electrically connected to the power input terminal; the first voltage conversion circuit 24 is used to convert the AC voltage input to the power input terminal into a first DC voltage and output it.

[0045] In this embodiment, the first voltage conversion circuit 24 can be implemented using a half-wave rectifier circuit, a full-wave rectifier circuit, or a voltage doubler rectifier circuit. The full-wave rectifier circuit includes a center-tapped full-wave rectifier circuit and a bridge full-wave rectifier circuit. In this embodiment, the first voltage conversion circuit 24 is implemented using a bridge full-wave rectifier circuit to convert AC voltage to DC voltage. Furthermore, the input terminal of the first voltage conversion circuit 24 can be equipped with an EMI electromagnetic filter circuit to reduce electromagnetic interference generated by the electronic device and protect the device from external electromagnetic interference. The output terminal of the first voltage conversion circuit 24 can be equipped with a capacitor filter circuit to smooth the DC voltage output.

[0046] Optionally, the drive power supply circuit 20 further includes a second voltage conversion circuit 25, the input terminal of the second voltage conversion circuit 25 being electrically connected to the output terminal of the first voltage conversion circuit 24; the second voltage conversion circuit 25 is used to receive the first DC voltage output by the first voltage conversion circuit 24 and output a second DC voltage.

[0047] In this embodiment, the second voltage conversion circuit 25 can be implemented using a buck converter. The buck converter can be implemented using a Buck converter, an isolated buck converter, etc. Specifically, the second voltage conversion circuit 25 can use the circuit structure corresponding to the BP87213 chip. It can be understood that in this circuit structure, the input voltage is rectified and output by the first voltage conversion circuit 24 to the second voltage conversion circuit 25. The filtered DC voltage is then sent to the primary winding of the transformer in the circuit structure to change the voltage level. On the primary side of the transformer, there is a switching transistor whose switching state is controlled by the BP87213 chip. The switching action of the transistor causes a change in the current in the primary winding of the transformer, thereby inducing a voltage in the secondary winding. The BP87213 chip is responsible for controlling the switching frequency and duty cycle of the transistor to adjust the output voltage. It adjusts the operating state of the transistor through a feedback signal to ensure a stable output voltage. Furthermore, the output voltage is fed back to the BP87213 chip through an optocoupler. The optocoupler is used for electrical isolation to ensure safe isolation between the output and input terminals. After processing, the feedback signal adjusts the switching frequency and duty cycle of the switching transistor to stabilize the output voltage. Furthermore, the AC voltage generated by the transformer secondary winding is rectified by a rectifier diode to obtain pulsating DC. This rectified pulsating DC is then filtered by a filter capacitor to obtain a smooth DC output voltage. The circuit also includes overvoltage protection; when the output voltage exceeds a set value, the protection mechanism is triggered, cutting off the switching transistor to prevent damage to the load. Similarly, overcurrent protection is also included; when the output current exceeds a set value, the protection mechanism is triggered, cutting off the switching transistor to protect the circuit and the load.

[0048] Optionally, the driving power supply circuit 20 further includes a driving circuit, the input terminal of which is electrically connected to the output terminal of the second voltage conversion circuit 25, the controlled terminal of which is electrically connected to the main control circuit 10, and the output terminal of which is electrically connected to the power supply terminal of the light-emitting diode circuit 30 and the main control circuit 10; the driving circuit is used to receive the driving control signal output by the main control circuit 10 and adjust the output current of the output terminal of the driving circuit.

[0049] The driving circuit includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first capacitor C1, a second capacitor C2, a first inductor L, a first diode D1, and a constant current driving chip.

[0050] Wherein, the first end of the first resistor R1 is electrically connected to the power control circuit 22; the second end of the first resistor R1 is electrically connected to the first end of the second resistor R2 and the second end of the constant current driving chip; the second end of the second resistor R2 is electrically connected to the ground terminal, the second end of the first capacitor C1, the second end of the fourth resistor R4, the second end of the fifth resistor R5, the fifth end of the constant current driving chip, and the sixth end of the constant current driving chip; the first end of the third resistor R3 is connected to the first end of the output terminal of the second voltage conversion circuit 25, the first end of the second capacitor C2, the first end of the first diode D1, and the light-emitting diode. The first terminal of circuit 30 is electrically connected; the second terminal of the third resistor R3 is electrically connected to the first terminal of the first capacitor C1, the first terminal of the constant current driving chip, and the third terminal of the constant current driving chip; the first terminal of the fourth resistor R4 is electrically connected to the first terminal of the fifth resistor R5 and the fourth terminal of the constant current driving chip; the first terminal of the sixth resistor R6 is electrically connected to the second terminal of the first diode D1; the second terminal of the sixth resistor R6 is electrically connected to the seventh terminal of the constant current driving chip, the eighth terminal of the constant current driving chip, and the first terminal of the first inductor L; the second terminal of the first inductor L is electrically connected to the second terminal of the light-emitting diode circuit 30.

[0051] In this embodiment, the constant current driver chip can be implemented using a Hi7003H chip. The PWM signal output from the power control circuit 22 is input to the second terminal of the Hi7003H. This signal is used to control the brightness of the LED circuit 30. The duty cycle of the PWM signal determines the average current of the LED circuit 30, thereby adjusting the output brightness of the LED circuit 30. The fourth resistor R4 and the fifth resistor R5 are connected in series in the loop of the LED circuit 30. When the current in the LED circuit 30 flows through the fourth resistor R4 and the fifth resistor R5, a voltage drop is generated, which is detected by the fourth terminal of the Hi7003H.

[0052] When the PWM signal output by the power control circuit 22 is high, the LD pin of the Hi7003H outputs a high level, the MOSFET is turned on, and current flows through the LED circuit 30, the fourth resistor R4, the fifth resistor R5, and the first inductor L to form a loop, causing the LED circuit 30 to emit light. The CS pin detects the voltage across the fourth resistor R4 and the fifth resistor R5. When the current reaches a preset value, the chip adjusts the output to maintain a constant current. When the PWM signal output by the power control circuit 22 is low, the LD pin outputs a low level, the MOSFET is turned off, and current flows through the first diode D1 to freewheel, preventing the inductor from generating a back electromotive force. By changing the duty cycle of the PWM signal, the average current of the LED circuit 30 can be adjusted, thereby achieving brightness adjustment.

[0053] In this embodiment, the light-emitting diode circuit 30 includes multiple light-emitting diodes connected in series. The first terminal of the light-emitting diode circuit 30 is electrically connected to the power output terminal of the driving power supply circuit 20, so as to output light of corresponding brightness under the drive of the driving power supply circuit 20.

[0054] By employing a lighting control circuit, the safety of the lighting power supply is effectively improved. The lighting control circuit includes a main control circuit 10, a driver power supply circuit 20, and a light-emitting diode (LED) circuit 30. The driver power supply circuit 20 includes a power input terminal, a controlled terminal, and a power output terminal. By electrically connecting the controlled terminal of the driver power supply circuit 20 to the main control circuit 10, the current at the power output terminal is adjusted upon receiving control signals from the main control circuit 10. Furthermore, the output terminal of the driver power supply circuit 20 is electrically connected to the output terminal of the LED circuit 30, thereby outputting a corresponding current to the LED circuit 30 to enable the LED circuit 30 to output light of a corresponding brightness. In addition, the output terminal of the driver power supply circuit 20 is also electrically connected to the power supply terminal of the main control circuit 10 to provide a stable voltage supply to the main control circuit 10. It can be understood that the LED circuit 30 is connected in parallel with the power supply terminal of the main control circuit 10, thereby utilizing the unidirectional conduction characteristic of the diode to clamp the power supply voltage, thus outputting a stable and reliable voltage to the main control circuit 10.
