[0069] Figure 9 As the overall circuit schematic diagram of the multifunctional switch controller, the core circuit architecture of the controller and the connection logic of each functional unit are completely presented, and key modules such as the power input and high-frequency conversion unit 5, the low-voltage load output unit 6, the lamp control execution unit 7, the common-mode interference suppression unit 8, the control power and signal processing unit 9, the USB charging function unit 10 and the centralized control communication unit 11 are covered. The circuit takes 200-240V mains as input, and after being processed by the power input and high-frequency conversion unit 5, on the one hand, it provides basic voltage for the low-voltage load output unit 6, thereby providing power for the low-voltage decorative lamp, and on the other hand, it provides adaptive power for the control power and signal processing unit 9, the USB charging function unit 10 and the like through related conversion and voltage stabilization circuit; at the same time, the PWM control signal output by the control power and signal processing unit 9 can control the lamp control execution unit 7, realize the on-off and brightness adjustment of the lamp, the common-mode interference suppression unit 8 guarantees the anti-interference ability of the circuit, and the centralized control communication unit 11 supports multi-controller signal transmission, and the overall circuit realizes the complete functions of power supply, lamp control, charging, anti-interference and multi-control cooperation.

[0070] Figure 10 The specific circuit structure of the power input and high-frequency conversion unit 5 is shown, and the unit takes 200-240V / 50-60Hz mains as input source, and the core includes rectification, filtering and high-frequency conversion related elements.

[0071] Figure 11 The low-voltage load output unit 6 primarily processes the high-frequency isolation voltage output from the power input and high-frequency conversion unit 5, converting it into a power supply voltage suitable for low-voltage decorative lighting fixtures. In the circuit, the high-frequency isolation voltage output from T1 is rectified by D3 and then filtered by filter components such as C4 and CE6 to remove residual AC components and interference signals, ultimately outputting a stable 12-24V suitable voltage. CN3 serves as the output interface, connecting to the light source line interface 203 to transmit the suitable voltage to the low-voltage decorative lighting fixtures, providing them with safe and continuous power. The circuit design is simple, ensuring voltage conversion efficiency and output stability, meeting the power supply needs of different types of low-voltage decorative lighting fixtures.

[0072] Figure 12 The lighting control execution unit 7 shown is the core execution link for realizing the on / off switching and brightness adjustment of low-voltage decorative lighting fixtures. The circuit uses CN3 as the connection interface with the low-voltage load output unit 6 and the lighting fixture, and receives the PWM1 control signal from the control power supply and signal processing unit 9. In the circuit, Q2 and Q3 are the core switching transistors, and resistors such as R11, R12, R14, and R15 are used to regulate the on and off states of the switching transistors. When the PWM control signal is input, the on / off frequency and duty cycle of Q2 and Q3 can be controlled, thereby regulating the voltage output state transmitted from the low-voltage load output unit 6 to the lighting fixture. When the switching transistors are continuously on, the lighting fixture is always on; when they are continuously off, the lighting fixture is off. By switching on and off according to a specific duty cycle, the brightness of the lighting fixture can be gradually adjusted. The CN4 interface helps to ensure the stable transmission of circuit signals and voltage, ultimately achieving precise control of the lighting fixture.

[0073] Figure 13 The circuit structure of common-mode interference suppression unit 8 is shown below. This unit has a simple structure, with the core component being the common-mode capacitor CY1. In the circuit, one end of CY1 is connected to the circuit's common ground terminal GND, and the other end is connected to the functional module's common ground terminal AGND, forming a common-mode interference filtering loop. During the operation of the controller, the circuit is susceptible to the influence of the external electromagnetic environment or the operation of internal components, generating common-mode interference signals. These interference signals may cause circuit instability, lamp flickering, or control signal malfunction. CY1 can effectively absorb and filter out common-mode interference signals in the circuit, preventing interference signals from transmitting and spreading in the circuit, significantly improving the electromagnetic compatibility of the entire controller circuit, and ensuring the stable and reliable operation of each functional module and lamp.

[0074] Figure 14The control power supply and signal processing unit 9 on display combines two core functions: power supply regulation and control signal generation. Its core components include a voltage regulator chip U2 and a PWM control chip U3. In the circuit, the VIN1 interface receives voltage from the low-voltage load output unit 6. After being regulated by the U2 voltage regulator chip, a stable voltage is output to power the U3 PWM control chip, ensuring stable operating voltage for U3. With stable power supply, the U3 chip generates and outputs a PWM control signal (PWM1), which is transmitted to the lighting control execution unit 7 via the line to regulate the lighting's operating state. Simultaneously, diodes such as D6, D7, D8, and D10 ensure unidirectional conductivity and prevent reverse surges; filters such as C5, C6, and C7 stabilize voltage and signals; and resistors such as R3, R4, R8, and R9 regulate circuit parameters. The unit also includes indicator light circuitry, allowing for intuitive feedback on the controller's operating status (such as normal operation or fault) through indicator light illumination or color changes.

[0075] Figure 15 The presented USB charging function unit 10 is a dedicated circuit for charging external electronic devices, with the core component being the USB charging chip U4. In the circuit, the VIN1 interface receives voltage from the low-voltage load output unit 6. The current is protected by the F2 fuse (which blows in case of abnormal current), and then filtered by filter elements such as C8, CE3, CE4, C9, and C10 before being input to the U4 charging chip. The U4 chip converts the input voltage to a standard 5V USB charging voltage, which is then used to charge external electronic devices such as mobile phones and tablets via the USB1 interface (connected to the external USB charging port 204 of the controller). Simultaneously, the D11 reverse connection protection diode prevents reverse charging by external devices from damaging the circuit. RS4 and RS5 are charging status detection resistors that can detect charging current, voltage, and other parameters in real time, providing feedback on the charging status (such as charging in progress, fully charged, fault, etc.). Resistors such as R19 and R20 assist in the control circuit, ensuring a safe, stable, and controllable charging process.

[0076] Figure 16The centralized control communication unit 11 shown primarily functions to achieve signal transmission and synchronous control between multiple controllers. Its core components include a centralized control interface CN2, an isolation diode D12, and a communication signal line TX1. In the circuit, the V interface receives the power supply voltage, which is isolated by the D12 isolation diode to prevent interference from voltage fluctuations between different controllers, ensuring stable communication power. CN2 serves as the centralized control interface for physical connection between multiple controllers, while TX1 is the communication signal line responsible for transmitting control signals (such as lamp on / off and brightness adjustment commands). When multiple controllers are connected in series, real-time transmission and synchronization of control signals between controllers can be achieved through the CN2 interface and the TX1 signal line. This ensures consistent control commands for the same low-voltage decorative lamp from controllers in different locations, avoiding control conflicts and enabling multi-location synchronous lighting control.

[0077] The working principle of this multi-functional switch controller is as follows:

[0078] When the controller is connected to 220V AC power, the 220V power interface 202 supplies power to the built-in functional modules:

[0079] The power input and high-frequency conversion unit 5 receives mains power, and outputs a high-frequency isolation voltage after rectification, filtering and high-frequency conversion.

[0080] The low-voltage load output unit 6 rectifies and filters the high-frequency isolation voltage to a 12-24V adaptive voltage. Part of it powers the low-voltage decorative lamps through the light source line interface 203, and the other part powers the PWM control chip U3 after being regulated by the voltage regulator chip U2. At the same time, it provides voltage to the USB charging function unit 10.

[0081] When the user touches the touch point 402 on the face cover 4, the touch switch module 12 transmits the signal to the PWM control chip U3. The PWM control chip U3 outputs the corresponding PWM control signal to the lamp control execution unit 7. The lamp control execution unit 7 controls the output of the adapter voltage by switching the switch tube to realize the lamp on / off or brightness adjustment.

[0082] When an external electronic device is plugged into the USB charging port 204, the fuse F2 and filter element of the USB charging function unit 10 process the input voltage and convert it into a 5V charging voltage through the USB charging chip U4 to charge the device. The charging status detection resistors RS4 and RS5 detect the charging status in real time.

[0083] The common-mode capacitor CY1 of the common-mode interference suppression unit 8 filters out common-mode interference signals in the circuit, ensuring circuit stability.

[0084] When multiple controllers are connected in series, signal synchronization is achieved through the central control interface CN2 of the central control communication unit 11 and the communication signal line TX1 to ensure the consistency of multi-position control;

[0085] The indicator lights of the power supply and signal processing unit 9 display the controller's operating status in real time, making it convenient for users to view.

[0086] The multi-functional switch controller of this embodiment can be easily installed by adapting to the universal 86-type switch box, integrates multiple functional modules to meet diverse needs, has a snap-fit ​​assembly for easy maintenance, and multi-position control to improve ease of use. It effectively solves many defects of traditional low-voltage decorative lighting controllers and is suitable for control scenarios of low-voltage lighting fixtures such as cabinet lights, wardrobe lights, decorative painting matching lights, and bedroom decorative lights in home decoration.
