The light source hole 12 and the first opening 13 are arranged opposite to each other. The light source hole 12 is used for allowing light to enter the interior of the refraction cup 1, and the first opening 13 is used for allowing light inside the refraction cup 1 to be emitted.

[0030] A grid array 11 is arranged on the inner wall of the refraction cup 1, and the grid array 11 includes a plurality of rectangular grid microstructures, and the sides of the plurality of grid microstructures away from the outer shell 2 are all arranged with quadratic surfaces; specifically, the quadratic surface of the rectangular grid microstructure is an ellipsoidal surface, and the grid array 11 can reflect and distribute light, reduce the disorderly reflection of light, thereby reducing glare and improving the uniformity of lighting. The arrangement of the rectangular grid microstructure and the design of the quadratic surface work together on the distribution of light, further reducing the occurrence of glare, so that the lighting effect is more in line with the visual effect of the human body.

[0031] It should be noted that, in the embodiment of the present application, one end of the refraction cup 1 close to the first opening 13 extends outward to form a first extension portion 14 , and a first slot 15 is provided on the first extension portion 14 so that the refraction cup 1 can be installed on the housing 2 .

[0032] like Figure 1 and Figure 3 As shown, the shell 2 is specifically a trumpet-shaped plastic cup, which is sleeved on the outer wall of the refraction cup 1. The two ends of the shell 2 are respectively provided with a second opening 21 and a third opening 22, which are respectively matched with the light source hole 12 and the first opening 13, so that light can pass through the refraction cup 1 through the light source hole 12 and the first opening 13, thereby protecting the refraction cup 1 and preventing the refraction cup 1 from being hit during use and causing structural damage.

[0033] In the embodiment of the present application, one end of the shell 2 near the third opening 22 extends outward to form a second extension portion 23, and a second card slot 24 is provided on the second extension portion 23. The specifications of the second card slot 24 are the same as those of the first card slot 15. One end of the shell 2 near the second opening 21 extends inward to form a flat third extension portion 25, and a third card slot 26 is provided on the third extension portion 25.

Quadrilateral protrusions 312 are provided between adjacent octagonal protrusions 311, and both the octagonal protrusions 311 and the quadrilateral protrusions 312 are provided with arc surfaces protruding outward. After the light is refracted by the octagonal protrusions 311 and the quadrilateral protrusions 312, the original path of the light is changed, and the light becomes cross-mixed to achieve a uniform light spot effect. At the same time, since the polygonal protrusion 31 is a mixture of octagon and quadrilateral, a mixed light spot that is closer to a circle can be formed, so that the lighting effect is more in line with the visual effect of the human body.

Finally, while connecting the light-transmitting plate 3, the refraction cup 1 and the outer shell 2, the positions of the outer shell 2 and the refraction cup 1 are limited to ensure the stability of the structure of the reflector.

[0038] like Figure 6As shown, the connecting plate 4 is specifically an annular insulating plate, and a first claw 41 extending to one side is provided on the inner wall of the connecting plate 4, and the first claw 41 is matched with the third clamping groove 26. A second claw 42 extending to the other side is also provided on the inner wall of the connecting plate 4, and the extension direction of the second claw 42 is opposite to the extension direction of the first claw 41. A fourth clamping groove 43 is provided on the outer wall of the connecting plate 4; the connecting plate 4 can be detachably connected to the housing 2 through the first claw 41 and the third clamping groove 26, thereby ensuring the convenience of installation of the connecting plate 4 and the housing 2, and the first claw 41 and the second claw 42 extend in opposite directions, which helps to achieve connection requirements in different directions, making the structure of the entire reflector more stable and reliable. At the same time, the existence of the fourth clamping groove 43 provides an additional connection point for the connecting plate 4, increasing the assembly flexibility and stability of the entire reflector.

[0041] like Fig. 9 and Fig.10As shown, the reflector in the embodiment of the present application is also provided with a driving assembly 6, which includes a shell 61, a first transmission gear 62, a second transmission gear 63, a rotating tube 64, a limiting rod 65 and a driving motor 66. The shell 61 is threadedly connected to the output end of the driving motor 66, and the fixed end of the driving motor 66 is fixed to the ceiling; specifically, the shell 61 in the embodiment of the present application is provided with two symmetrical through holes, and the two through holes are arranged opposite to the output end of the driving motor 66, and threads are arranged on the hole walls of the two through holes. The output end of the driving motor 66 passes through the shell 61 through the two through holes, and is threadedly connected to the shell 61 through the threads on the hole walls of the two through holes.

[0042] Alternatively, if Fig.10 As shown, in the embodiment of the present application, a thickening block 7 is further provided on the inner wall of the shell 61 on the side close to the drive motor 66, and the thickening block 7 is provided with a through hole with the same specifications as the through hole on the side close to the drive motor 66, and a thread is provided on the hole wall of the through hole on the thickening block 7; the thickening block 7 is used to increase the contact area between the shell 61 and the drive motor 66 to improve the output efficiency of the drive motor 66.

[0043] The first transmission gear 62 and the second transmission gear 63 are both horizontally arranged, and the first transmission gear 62 and the second transmission gear 63 are both rotatably arranged on the inner wall of the shell 61. The center hole of the first transmission gear 62 is smaller than the center hole of the second transmission gear 63. Threads are arranged on the hole wall of the first transmission gear 62 and the center hole. The center hole of the first transmission gear 62 is arranged opposite to the output end of the driving motor 66.

[0044] The second transmission gear 63 is meshed with the first transmission gear 62. The shell 61 is provided with a hole at a position opposite to the center hole of the second transmission gear 63. The aperture of the hole is larger than the aperture of the second transmission gear 63. One end of the rotating tube 64 passes through the center hole of the second transmission gear 63 and then passes through the shell 61 through the hole of the shell 61. The end of the rotating tube 64 passing through the shell 61 is rotatably connected to a side of the lamp holder 5 away from the outer shell 2. The outer wall of the rotating tube 64 is fixedly connected to the inner wall of the second transmission gear 63.

[0045] It should be noted that, in the embodiment of the present application, the lamp holder 5 is eccentrically arranged with the rotating tube 64, that is, the central axis of the lamp holder 5 is not in the same straight line with the central axis of the rotating tube 64. When the driving motor 66 is working, it can drive the shell 61 to move in the vertical direction, thereby driving the rotating tube 64 to move in the vertical direction, and then driving the lamp holder 5 to move in the vertical direction, and finally driving the bulb 53 to move in the vertical direction, thereby adjusting the height of the bulb 53, increasing the distance between the bulb 53 and the irradiation surface, reducing the brightness, reducing the occurrence of glare, and further improving the problem that the existing lighting equipment is prone to glare; at the same time, the lamp holder 5 eccentrically arranged with the rotating tube 64 can rotate with the rotation of the rotating tube 64, change the irradiation position of the light source, reduce the occurrence of direct light source, reduce the occurrence of glare, and further improve the problem that the existing lighting equipment is prone to glare.

The rotating tube 64 passes through the threaded hole of the limit rod 65 and is threadedly connected with the limit rod 65; the "L"-shaped limit rod 65 can provide a stable support point and limit point for the rotating tube 64, which helps to provide vertical guidance and restriction when the rotating tube 64 rises or falls; the threaded connection between the limit rod 65 and the rotating tube 64 can allow the rotating tube 64 to move vertically on the limit rod 65, and provide position control through the spiral shape of the thread.
