[0062] In one embodiment, such as Figure 3 As shown, the signal processing module includes resistors R7, R8, R12, capacitors C6 and C7, and operational amplifiers U4A and U4B; wherein,
[0063] The first terminal of R7 is the input terminal PWM_OUT of the signal processing module. The second terminal of R7 is connected to the first terminal of C6 and the input terminal of U4A. The second terminal of C6 is grounded. The first output terminal of U4A is connected to the input terminal of U4B. The second output terminal of U4A is connected to the first terminal of R8 and the first terminal of R12. The second terminal of R12 is grounded. The second terminal of R8 is connected to the first output terminal of U4A. The first output terminal of U4B is the output terminal DIM+ of the signal processing module. The second output terminal of U4B is connected to the first terminal of C7. The second terminal of C7 is grounded.
[0064] In practice, R7 and C6 form a low-pass filter to convert the PWM signal output by U1 into an analog dimming signal of 0~10V. After being amplified by U4A, the signal is then output to the LED driver power supply 21 via U4B.
[0065] In one embodiment, the human motion sensing module U3 is used to detect the presence and movement of a human body. For example... Figure 4 As shown, the output terminal REL of the human motion sensing module U3 is connected to the fourth terminal (pin 7 of the microcontroller U1), and the human motion sensing module U3 outputs the detected human motion signal to the microcontroller U1.
[0066] In practice, the human motion sensing module can be a PIR pyroelectric infrared sensor or a microwave human body sensor.

[0070] The first terminal 1 of the second optocoupler OC2 is the input terminal VLG of the second switch control module; the second terminal 2 of the second optocoupler OC2 is grounded; the third terminal 3 of the second optocoupler OC2 is connected to the third terminal 3 of the second switch element Q2 and the negative power supply V- of the second switch control module; the fourth terminal 4 of the second optocoupler OC2 is connected to the first terminal 1 of the second switch element Q2 and the positive power supply V+ of the second switch control module; the second terminal 2 of the second switch element Q2 is the output terminal VL of the second switch control module.
[0071] In one embodiment, the first and second switching elements can be N-channel field-effect transistors (NMOS). Using field-effect transistors as switches to control the lighting of the lamps makes the entire control circuit simple and reliable.
[0072] In one embodiment, the aforementioned human motion sensing controller further includes an infrared receiver. Figure 6 This is a schematic diagram of the infrared receiver provided in the embodiments of this utility model, such as... Figure 6 As shown, the signal output terminal OUT of the infrared receiver U5 is connected to the eighth terminal of the microcontroller U1 (pin 5 of the microcontroller U1).
[0073] In practice, the infrared receiver U5 can receive infrared remote control signals to set relevant parameters of the human motion sensing controller, such as delay time, standby time, and LED light panel brightness.
[0074] Based on the aforementioned LED driver power supply control device, its implementation process can be as follows: If the infrared receiver U5 receives an infrared remote control signal and transmits the remote control signal to the microcontroller U1, the microcontroller U1 will parse the infrared remote control signal and rewrite the relevant instructions within the microcontroller U1. Secondly, by detecting the light sensing parameters of the light sensing element connected to the light sensing element's connection port, the microcontroller U1 determines the environmental state of the light sensing element (i.e., daytime or nighttime). When the light sensing element is in nighttime, the microcontroller U1 detects human movement through the human motion sensing module U3. If the human motion sensing module... If human movement is detected within the detection area of block U3, the signal processing module processes the signal and outputs it to the LED driver to control the lighting of the lamp (brightness is determined by the duty cycle of the PWM signal emitted by U1, referred to as "holding brightness," using a high color temperature LED panel). If no human movement is detected within the detection area for a continuous period of time (referred to as "holding time"), the lamp brightness will be dimmed (referred to as "standby brightness," using a low color temperature LED panel) or the lamp will be turned off. Alternatively, the lamp may be turned off after the brightness has dimmed for a period of time (referred to as "standby time"). In this way, the automatic on / off, color temperature, and brightness of LED smart lighting lamps can be controlled based on human movement, greatly reducing the power consumption of the lamps when no one is present and meeting the diverse dimming needs of users.
[0075] It should be noted that in this embodiment of the utility model, the LED driver power supply control device adopts a modular design method, which makes the control circuit simple and reliable, and can be disassembled and assembled as needed, which is convenient and quick.
[0076] In summary, the LED driver power supply control device provided in this embodiment of the present invention is used to control an LED light panel, which includes a high color temperature light panel and a low color temperature light panel.
