[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] like Figure 1 to Figure 3 As shown, the utility model provides a glare-reducing annular lens with a diamond-shaped structure on the surface, comprising an annular lens body 1, the lower surface of the annular lens body 1 being an arc-shaped light incident surface 11, the upper surface of the annular lens body 1 being an arc-shaped light emitting surface 12, a diamond-shaped structure 13 being provided on the arc-shaped light incident surface 11, and the curvature of the arc-shaped light incident surface 11 being smaller than the curvature of the arc-shaped light emitting surface 12. The utility model uses a clever annular design and a diamond-shaped grid structure, and designs the curvature of the arc-shaped light incident surface 11 to be smaller than the curvature of the arc-shaped light emitting surface 12, thereby achieving the purpose of reducing glare, uniforming light, and increasing aesthetics. At the same time, the curvature design of the annular lens can avoid directly looking at the LED inside the lamp, and plays a covering role, so that the observer will not look directly at the internal structure of the lamp. The entire lens design is beautiful and has a practical optical effect.

[0023] The rhombus structure 13 includes a plurality of rhombus arc surface dots arranged in sequence, the arc light exiting surface 12 is arc-shaped as a whole, and a single rhombus arc surface dot is substantially rhombus-shaped. In the top view of the lens of the utility model, a single rhombus arc surface dot is substantially rhombus-shaped. Moreover, the area of ​​each rhombus arc surface dot is substantially equal (except for the dots in the edge area, the areas of the rest are substantially equal, that is, the rhombus arc surface dots in the utility model are uniform in size and uniformly distributed).

[0024] The diamond structure 13 is disposed in the outer ring region of the arc-shaped light-emitting surface 12 , and the inner ring region of the arc-shaped light-emitting surface 12 is a frosted surface.

[0025] One end of the arcuate light emitting surface 12 is connected to one end of the arcuate light incident surface 11 via an arcuate surface 14, and the other end of the arcuate light emitting surface 12 is connected to the other end of the arcuate light incident surface 11 via a mounting component 15. The mounting component 15 is used to mount the entire lens to a desired position.

[0026] The distance between one end of the arcuate light emitting surface 12 and one end of the arcuate light incident surface 11 is smaller than the distance between the other end of the arcuate light emitting surface 12 and the other end of the arcuate light incident surface 11. In other words, the thickness of one end of the annular lens of the present invention is smaller than the thickness of the other end.

[0027] The curvature increases gradually from one end of the arc-shaped light-emitting surface 12 to the other end of the arc-shaped light-emitting surface 12; the curvature increases gradually from one end of the arc-shaped light-entering surface 11 to the other end of the arc-shaped light-entering surface; and the increase in the curvature of the arc-shaped light-emitting surface 12 is greater than the increase in the curvature of the arc-shaped light-entering surface 11. In other words, the arc-shaped light-entering surface 11 is smoother than the arc-shaped light-emitting surface 12.

[0028] An LED lamp 2 is arranged below the arc-shaped light incident surface 11. The light emitted by the LED lamp 2 enters from the arc-shaped light incident surface 11 and then diverges from the diamond structure 13. In this way, it is possible to avoid directly looking at the LED inside the lamp, and it plays a covering role so that the observer will not directly see the internal structure of the lamp.

[0029] The arc-shaped light incident surface 11 is a frosted surface.

[0030] The inner ring area of ​​the arc-shaped light-emitting surface 12 and the arc-shaped light-entering surface 11 are both frosted surfaces. Both areas will have a certain degree of atomization effect based on the visual effect of the lamp, rather than being smooth surfaces. The frosted design of the two is combined with the curvature to increase the degree of curvature of the light divergence, while the external dot surface will amplify the divergence effect to reduce glare.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and structures of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
