Abstract: Provided is an LED power supply integrated junction box, which includes a main body and a bottom cover. One side of an inner wall of the main body is connected with multiple positioning hollow columns. A partition is fixedly connected to the middle of the main body. Two small circular through holes are defined in one side of the partition. The opposite surfaces of the partition and the inner wall of the main body are each fixedly connected with multiple clamping grooves.

Abstract: A method of controlling light adjustment include activating a power supply; activating a digital control circuit to carry out an adjustment output voltage control mode, sense a signal from a light adjustment control switching circuit, and determine a light adjustment control mode; in response to an LED power source operating in the adjustment output voltage control mode, adjusting luminance from 100% to N % and continuously adjusting luminance from N % to ?0.01% wherein a 100% PWM signal output from a PWM driving signal circuit is unchanged, and a light adjustment signal collection circuit transmits a collected light adjustment signal having luminance between N % and ?0.01% to the digital control circuit; in response to the LED power source operating in a PWM adjustment control mode, adjusting luminance from 100% to N % and continuously adjusting luminance from N % to ?0.01%; and obtaining a light adjustment curve.
