[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-4As shown, this specific embodiment adopts the following technical solution: It includes a base 1, a microcomputer control system 2 is installed inside the base 1, several heat dissipation holes are opened on the ring wall of the base 1, a photosensitive tube 4 is installed on one side of the base 1 using a support arm 3 with an "L" shape, a pinhole 4-1 is opened on one end wall of the photosensitive tube 4, a diffuser 5 is installed inside the photosensitive tube 4, and a photosensitive tracker 6 is installed inside the other end wall of the photosensitive tube 4; an optical reflector 10 is movably installed on the top of the base 1 using a support arm 8 with an arc shape, the optical reflector 10 is made of high-reflectivity nano-coated glass; the optical reflector 10 is arranged opposite to the photosensitive tube 4; a stepper motor 9 is mounted on the upper side wall of the support arm 8 using a bracket, the upper end of the support arm 8 is movably connected to the universal joint seat 12 on the back of the optical reflector 10 using a universal joint, the output end of the stepper motor 9 is connected to a gear 14, the gear 14 is meshed with an arc-shaped rack 13, the arc-shaped rack 13 is installed on the back of the optical reflector 10; the lower end of the support arm 8 is mounted on a rotating... On the rotating base 11, the bottom of the rotating base 11 is rotatably mounted on the base 1 using a planar thrust ball bearing. The output end of stepper motor 7 passes through the top wall of the base 1 and the planar thrust ball bearing, and is connected to the rotating base 11. Stepper motor 7 is mounted on the inner top of the base 1. Stepper motor 7, stepper motor 9, and photosensitive tracker 6 are all electrically connected to the microcomputer control system 2. The microcomputer control system 2 includes a control circuit board 2-1 and a stepper motor driver 2-2. The control circuit board 2-1 is located inside the base 1. The stepper motor driver 2-2 is located inside the base 1 and is electrically connected to the photosensitive tracker 6, control circuit board 2-1, stepper motor 7, and stepper motor 9.

[0022] When using this invention, sunlight shining from the optical reflector 10 into the pinhole 4-1 is scattered by the diffuser 5 and then guided by the photosensitive tube 4 to the photosensitive tracker 6. After receiving the light, the photosensitive tracker 6 performs real-time detection and dynamic tracking (light position and light intensity) and transmits the signal to the control circuit board 2-1. The control circuit board 2-1 analyzes and processes the transmitted signal. When the light position or light intensity does not meet the lighting requirements, the stepper motor driver 2-2 drives the stepper motor 7 and the stepper motor 9 to work, thereby controlling the angle adjustment of the support arm 8 and the optical reflector 10 until the light reflected from the optical reflector 10 and collected by the photosensitive tracker 6 meets the requirements, at which point the operation stops.
