[0059] The output of the signal conversion module is connected to the positive terminal DIM+ of the dimming port of the LED driver power supply 21 through the dimming control port DIM_OUT;

[0060] The output of the first switch module is connected to the high color temperature connection port A of the LED board 1 through the high color temperature control port VH; the output of the second switch module is connected to the low color temperature connection port B of the LED board 1 through the low color temperature control port VL.

[0063] The first terminal of the first resistor R8 is the input terminal PWM_OUT of the signal conversion module. The second terminal of the first resistor R8 is connected to the first terminal of the first capacitor C6 and the input terminal of the first operational amplifier U3A. The second terminal of the first capacitor C6 is grounded. The first output terminal of the first operational amplifier U3A is connected to the input terminal of the second operational amplifier U3B. The second output terminal of the first operational amplifier U3A is connected to the first terminal of the second resistor R16 and the first terminal of the third resistor R12. The second terminal of the second resistor R16 is grounded. The second terminal of the third resistor R12 is connected to the first output terminal of the first operational amplifier U3A. The first output terminal of the second operational amplifier U3B is the output terminal of the signal conversion module. The second output terminal of the second operational amplifier U3B is connected to the first terminal of the second capacitor C7. The second terminal of the second capacitor C7 is grounded.

[0064] In practice, R8 and C6 form a low-pass filter to convert the PWM signal output by U1 into an analog signal. After being amplified by U3A, the signal is then output to the dimming port of the LED driver power supply 21 via U3B.

[0065] like Figure 4 As shown, both the first switch switching module and the second switch switching module include a switch element and an optocoupler. Specifically, the first switch switching module includes a first switch element Q1 and a first optocoupler OC1; the second switch switching module includes a second switch element Q2 and a second optocoupler OC2.

[0066] 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.

[0067] like Figure 5 As shown, the Hall sensor module includes a first Hall sensor U4, a second Hall sensor U5, and a third Hall sensor U6 connected in parallel.

[0068] The output terminal DO of the first Hall sensor U4 is connected to the first control terminal D_CCT of the Hall sensor module; the output terminal DO of the second Hall sensor U5 is connected to the second control terminal D_POWER of the Hall sensor module; and the output terminal DO of the third Hall sensor U6 is connected to the third control terminal D_POWER of the Hall sensor module.

[0069] Continue to refer to Figure 5 A fourth resistor R17 is connected between the output and input terminals of the first Hall sensor, and a third capacitor C8 is coupled between the input terminal and the ground terminal of the first Hall sensor; a fifth resistor R18 is connected between the output and input terminals of the second Hall sensor, and a fourth capacitor C9 is coupled between the input terminal and the ground terminal of the second Hall sensor; a sixth resistor R19 is connected between the output and input terminals of the third Hall sensor, and a fifth capacitor C10 is coupled between the input terminal and the ground terminal of the third Hall sensor.

[0070] In practice, using Hall effect sensors as control and detection elements can solve the mechanical lifespan problem caused by traditional switch control and the need to manually adjust the lights by turning them on during use, thus solving the waterproofing problem of outdoor lights to some extent.

[0071] In one embodiment, the Hall sensor controller may further include a Hall indicator module. Figure 6 The circuit diagram of the Hall indicator module provided in the embodiments of this utility model is as follows: Figure 6 As shown, the Hall indicator module may include a first indicator LED1, a second indicator LED2, and a third indicator LED3 connected in parallel;

[0072] Specifically, the first indicator LED1 is connected to the output terminal of the first Hall sensor; the second indicator LED2 is connected to the output terminal of the second Hall sensor; and the third indicator LED3 is connected to the output terminal of the third Hall sensor.

[0073] In practice, after Hall sensors U4, U5, and U6 are triggered, the results can be displayed via LED1, LED2, and LED3, respectively. Additionally, Figure 6 In this system, each indicator light is connected in series with a resistor to limit excessive current and ensure that each indicator light receives an appropriate current for better illumination and longer lifespan.

[0074] Based on the aforementioned LED driver power supply control device, its implementation process can be as follows: First, by detecting the output signal of the Hall sensor U6 through the microcontroller U2, the enable state of the first external port (P+, P-) can be determined. When the first external port (P+, P-) is in the enabled state, the microcontroller U2 collects the AD data at both ends of the first external port (P+, P-) to implement the command to turn the LED driver power supply output off or on; Second, by detecting the voltage of the second external port and the output signal of the Hall sensor U5 through the microcontroller U2, the adjustment of the LED lamp brightness can be determined. The PWM signal output from microcontroller U2 is converted into an analog signal by a low-pass filter composed of R8 and C6. This analog signal is then amplified by U3A and output to the dimming port of the LED driver power supply via U3B, thereby adjusting the output power (or brightness) of the LED lamp. Next, the color temperature of the lamp is determined by detecting the output signal of Hall sensor U4. Microcontroller U2 then outputs a PWM signal, which controls the switching of Q1 and Q2 via OC1 and OC2. This allows for color temperature adjustment by mixing two LEDs with significantly different color temperatures. Simultaneously, the triggering of Hall sensors U4, U5, and U6 can be displayed via LED1, LED2, and LED3, respectively.

[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, this utility model embodiment provides an LED driver power supply control device, including: an LED driver power supply and a Hall sensor controller; the Hall sensor controller has a first external port, a second external port, a dimming control port, a high color temperature control port, a low color temperature control port, a positive power supply port, and a negative power supply port; the first external port is connected to an external control element; the first end of the second external port is connected to a dimming device, and the second end of the second external port is connected to the negative terminal of the dimming port of the LED driver power supply; the dimming control port is connected to the positive terminal of the dimming port of the LED driver power supply; the high color temperature control port is connected to the high color temperature connection port of the LED light panel; the low color temperature control port is connected to the low color temperature connection port of the LED light panel; the positive power supply port is connected to the positive terminal of the LED light panel and the positive terminal of the LED driver power supply respectively; the negative power supply port is connected to the negative terminal of the LED driver power supply.
