[0047] The dimming component 8 mentioned above adjusts the degree of convergence of the illumination of the LED light-emitting device 62, mainly by adjusting the distance between the Fresnel lens 84 and the LED light-emitting device 62, so that the refraction angle of the light emitted by the LED light-emitting device 62 changes. Compared with the traditional lens, the Fresnel lens 84 is different in shape. It divides the lens into a series of circular or wedge-shaped convex and concave circular structures, making the lens flat and thin.

[0049] Working principle: When the device needs to be used to adjust the degree of convergence and divergence of the irradiated light, it is first necessary to start the driving motor 74 to drive the gear 72 to rotate. At this time, the gear 72 will drive the outer gear ring 73 to rotate, and the rotating cylinder 82 will be driven to rotate together. Since the bottom end of the fixed cylinder 81 is fixed on the base 61, the rotating cylinder 82 can rotate in the outer shell 1. Each slide groove 86 and the extrusion groove 87 always have an intersection on the X-axis. The four slide bars 85 fixed on the movable ring 83 will pass through the intersection, and the extrusion groove 87 will squeeze the slide bar 85, causing it to move up and down along the slide groove 86, thereby changing the distance between the Fresnel lens 84 and the LED light-emitting device 62, so that it can change the refraction angle of the light of the LED light-emitting device 62, thereby changing the final degree of convergence of the light.
