Figure 4 The relevant modules and relevant connection interfaces of the wireless signal transceiver circuit are indicated. The light adjustment circuit includes a main power supply circuit 1 and multiple identical regional light source circuits 2; the regional light source circuit 2 includes a coding pair circuit 3, a wireless signal transceiver circuit 4, a radar sensing circuit 5 and an LED module 20. The coding pair circuit 3 includes an MCU module 21 and a coding module 22. One end of the MCU module 21 is connected to the output end of the main power supply circuit 1, and the other end of the MCU module 21 is connected to the coding module 22. The different functional connection ends of the MCU module 21 are respectively connected to the corresponding ports of the wireless signal transceiver circuit 4 and the sensing module. The coding module 22 includes multiple coding switches. One end of the coding module 22 is connected to one of the functional connection ends of the MCU module 21, and the other end of the coding module 22 is grounded. The coding switches form multiple pair coding forms for confirming other regional light source circuits 2 with the same lighting requirements as this regional light source circuit 2. , the regional light source circuits 2 with the same coding form are matched with each other according to the coding form to form corresponding coding switch pairs, and there are multiple coding forms; the wireless signal transceiver circuit 4 includes a signal transceiver module, the signal transceiver module includes a signal transceiver unit 40 and multiple signal connection ports, the signal connection ports are respectively connected to multiple functional connection terminals of the MCU module 21, and the signal transceiver unit 40 is used to transmit and receive switch control signals; the radar sensing circuit 5 includes a radar sensing module 50, the radar sensing module 50 includes a radar sensing unit and a sensor connection port, the sensor connection port is respectively connected to multiple functional connection terminals of the MCU module 21, the radar sensing unit is used to receive radar signals and convert them into corresponding control signals and send them to the MCU module 21; one end of the LED module 20 is connected to one of the functional connection terminals of the MCU module 21, and the MCU module 21 controls the LED module 20 to start the light through the corresponding control signal.

[0025] In actual use, this lighting control circuit with internal matching functionality primarily includes the following components: a main power supply circuit 1, multiple area light source circuits 2, a coding pairing circuit 3, a wireless signal transceiver circuit 4, a radar sensor circuit 5, and an LED module 20. In actual use, when a user of this lighting control circuit with internal matching functionality enters a warehouse or conference room, their thermal image or footsteps are detected by a radar sensor module 50 mounted on the ceiling. The radar sensor module 50 includes a radar sensing unit that detects human thermal radiation and movement and converts these physical signals into electrical signals. The radar sensing unit converts the detected signals into digital signals and transmits them to the MCU module 21 via a sensor connection port. The MCU module 21 (microcontroller unit) is a circuit with an integrated processor that receives signals from the radar sensing unit and performs appropriate processing and decision-making. Based on the received signal, the MCU module 21 generates a specific code using the coding switches in the coding module 22. This code is compared with a pre-set pairing code format to determine whether any other area light source circuits 2 match the current one. If a matching circuit is found, the MCU module 21 sends a control signal to that circuit via the wireless signal transceiver circuit 4. The local light source circuit 2, receiving the control signal, activates the connected LED module 20, illuminating the light. The LED module 20 is a highly efficient light source that adjusts its brightness according to the instructions of the MCU module 21 to adapt to different environmental requirements. The entire room is divided into multiple independent zones, each with a corresponding local light source circuit 2. Each local light source circuit 2 has a unique code, ensuring that it can only be matched with other local light source circuits 2. Since only the local light source circuit 2 associated with the user's location is activated, significant energy savings can be achieved. Rather than illuminating the entire room, lighting is provided only in the user's active area, reducing power consumption. The system can dynamically adjust the code and lighting control strategy based on user behavior patterns and environmental changes. For example, if a zone is frequently visited during a specific time period, the system can automatically increase the lighting time in that zone, while reducing it when no one is present. In this way, the lighting adjustment circuit with internal matching function not only provides necessary lighting but also intelligently adjusts the lighting according to user needs and environmental changes, achieving higher energy efficiency and user satisfaction.

[0026] First, the main power supply circuit 1 provides power for the entire circuit. The regional light source circuit 2 is the basic unit of the circuit. Multiple regional light source circuits 2 are matched to each other via a coding pairing circuit 3. The coding pairing circuit 3 includes an MCU module 21 and a coding module 22. One end of the MCU module 21 is connected to the output of the main power supply circuit 1, and the other end is connected to the coding module 22. The functional connection terminals of the MCU module 21 are respectively connected to corresponding ports of the wireless signal transceiver circuit 4 and the radar sensing circuit 5. The coding module 22 includes multiple coding switches, forming various pairing coding formats, which are used to identify other regional light source circuits 2 with the same lighting requirements. Regional light source circuits 2 with the same coding format can be matched to form corresponding coding switch pairs. The wireless signal transceiver circuit 4 includes a signal transceiver module, whose functional connection ports are respectively connected to the multiple functional connection terminals of the MCU module 21. The signal transceiver unit 40 is used to transmit and receive switch control signals to control the LED modules 20. The radar sensing circuit 5 includes a radar sensing module 50, whose functional connection ports are respectively connected to the multiple functional connection terminals of the MCU module 21. The radar sensing unit is used to receive radar signals and convert them into corresponding control signals and send them to the MCU module 21. One end of the LED module 20 is connected to one of the functional connection ends of the MCU module 21, and the MCU module 21 controls the LED module 20 to start the light through the corresponding control signal. In actual use scenarios, the radar sensing module 50 can sense the user's thermal imaging or footsteps. The entire light adjustment circuit is set in the entire room, such as a large warehouse or conference room. The warehouse or conference room has multiple entrances, and users usually do not need to turn on all the lights in the entire room. Therefore, it is only necessary to encode the associated area light source circuit 2 in advance to form a group pair between multiple areas. When in use, the lights in the associated areas can be turned on by induction and signal sensing control, and the lights in the unassociated areas will not be turned on, thereby saving unnecessary energy consumption.

[0027] In summary, the lighting control circuit with internal matching functionality in this embodiment can effectively improve energy efficiency and user experience. For example, in a large warehouse or conference room, when a user enters, they do not need to manually turn on all lights. Instead, the radar sensor module 50 can sense the user's presence. When the radar sensor module 50 detects the user's thermal image or footsteps, it converts the signal into a control signal and sends it to the MCU module 21. The MCU module 21 then searches for a regional light source circuit 2 with the same encoding format based on pre-set encoding pairing rules. Once a matching circuit is found, the MCU module 21 sends a control signal via the wireless signal transceiver circuit 4, turning on only the regional light source circuit 2 associated with the user's location, without affecting the lights in other areas. This intelligent lighting control system not only improves energy efficiency by illuminating only the required areas, but also provides convenience because users do not need to manually adjust the lights. Furthermore, this system can dynamically adjust based on usage. For example, if multiple users enter different areas at the same time, the system can simultaneously control the lights in multiple areas. To achieve such advanced functionality, the circuit design may also include additional intelligent algorithms such as motion detection, crowd counting and prediction, and automatic dimming. These algorithms can help the system better adapt to the needs of different scenarios and further improve user experience and energy efficiency.

[0028] Furthermore, the light adjustment circuit also includes a driving circuit 6, one end of which is connected to one of the functional connection ends of the MCU module 21. The driving circuit 6 includes a driving chip and a transistor. The output end of the driving chip and the base of the transistor are connected to a functional connection end of the MCU module 21, and the collector and emitter of the transistor are respectively connected to the driving chip.

[0029] Furthermore, the light adjustment circuit also includes a forced start circuit 7, which includes a forced start switch and an optocoupler. One end of the optocoupler is connected to the forced start switch, and the other end is connected to the main power supply circuit 1 through a linear regulator. The linear regulator is used to input voltage to the MCU module 21 and keep the voltage stable.

[0030] Furthermore, the LED module 20 includes a signal receiving end and a plurality of LED lamps. The signal receiving end receives a control signal from the MCU module 21 to control the LED lamps to turn on.

[0031] Specifically, the driver circuit 6 is an intermediate link connected between the MCU module 21 and the LED module 20. Its main function is to convert the control signal output by the MCU module 21 into a current capable of driving the LED module 20. The driver circuit 6 includes a driver chip and a transistor. The driver chip is typically a high-efficiency, low-power electronic device that amplifies the output signal of the MCU module 21 to drive the transistor. The transistor acts as a switch here. Its base is connected to the output of the driver chip, and its collector and emitter are connected to an external power supply and the LED module 20, respectively. When the driver chip outputs a high level, the transistor turns on, allowing current to flow through the LED module 20; when the output is a low level, the transistor turns off, stopping power to the LED module 20. The forced start circuit 7 includes a forced start switch and an optocoupler. An optocoupler is an optical isolator that electrically isolates the input and output terminals to prevent noise and overvoltage from affecting the MCU module 21. The forced start switch is typically a physical button that allows the user to manually start the light when necessary. When the user presses the forced-start switch, the optocoupler's input is activated, and its output transmits a signal to the MCU module 21, forcing it to ignore normal sensing control and directly start the LED module 20. One end of the optocoupler is connected to the forced-start switch, and the other end is connected to the main power supply circuit 1 via a linear regulator. The linear regulator ensures a stable voltage supplied to the MCU module 21, preventing voltage fluctuations from damaging the MCU module 21. The LED module 20 is the final execution unit of the circuit and contains multiple LED lamps and a signal receiver. The signal receiver is responsible for receiving control signals from the MCU module 21. These signals can be PWM (pulse-width modulation) signals, which are used to control the brightness of the LED lamps. The LED lamps turn on or adjust their brightness based on the received control signals. LED lamps are characterized by high efficiency, long life, and low heat generation, making them ideal for energy-saving lighting. Through these additional circuits and modules, the light control circuit not only implements automatic sensing control but also provides manual control and voltage stabilization, ensuring system reliability and flexibility. This design makes the light control circuit more comprehensive and adaptable to various usage scenarios and user needs.

[0032] Furthermore, the radar sensing module 50 includes a first resistor, which is disposed between the radar sensing unit and the sensor connection port.

[0033] Furthermore, the forced start circuit 7 includes a second resistor and a third resistor, which are connected in series and arranged in series between the optocoupler and the forced start switch.

[0034] Furthermore, the main power supply circuit 1 further includes a bridge rectifier diode, one end of which is connected to the regional light source circuit 2 and the other end of which is grounded.

[0035] Furthermore, the regional light source circuit 2 includes a first capacitor, one end of which is connected to the main power supply circuit 1 and the other end of which is grounded.

[0036] Furthermore, a first resistor is located between the radar sensing unit and the sensor connection port. Its primary function is to limit current flow and protect the radar sensing unit from overcurrent. When the radar sensing unit detects a person's thermal image or footsteps, it generates an electrical signal. The first resistor ensures that the amplitude of this signal is moderate, preventing damage to subsequent circuits due to excessive current. The second and third resistors are connected in series between the optocoupler and the forced-start switch. Their purpose is to limit current flow and protect the optocoupler and forced-start switch from overcurrent. When the user presses the forced-start switch, current flows through the second and third resistors before reaching the optocoupler. This design ensures that even if the forced-start switch is accidentally pressed for a long time, overcurrent will not damage the circuit. The bridge rectifier diode is a component of the main power supply circuit 1, used to convert AC power into DC power. One end of the bridge rectifier diode is connected to the local light source circuit 2, and the other end is grounded. This ensures that the local light source circuit 2 receives a stable DC voltage, which is crucial for the proper operation of the LED module 20. The first capacitor is a capacitor connected between the main power supply circuit 1 and ground, and its functions are filtering and decoupling. When the main power circuit 1 supplies current, the first capacitor helps smooth the voltage and reduce voltage fluctuations, thereby providing a more stable power supply to the local light source circuit 2. It also prevents high-frequency noise interference in the circuit, ensuring circuit stability and reliability. These additional components further enhance the performance of the light control circuit. They not only protect sensitive circuit components, but also ensure long-term stable operation and enhance user safety.

A lighting control circuit with internal matching function can effectively improve energy efficiency and user experience. For example, in a large warehouse or conference room, when a user enters, they do not need to manually turn on all the lights. Instead, the radar sensing module 50 can sense the user's presence.
