[0025] refer to Figures 1 to 5As an object of the present utility model, an anti-glare lens is provided, comprising a lens body 1, a peripheral ring body 2 and a base 3. The lens body 1 is provided with a placement hole 11 for placing a light source, and a light emitting surface 12 is formed on the side away from the light source. The lens body 1 has a first light incident surface 13 facing the placement hole 11, and the light emitting surface 12 includes a first light emitting surface 121. The first light emitting surface 121 is provided with a honeycomb structure. The first light emitting surface 121 is opposite to the first light incident surface 13, and the first light incident surface 13 is used to refract the outgoing light passing therethrough to the first light emitting surface 121. The peripheral ring body 2 surrounds the radial edge of the lens body 1 and accommodates the lens body 1 therein, that is, the peripheral ring body 2 extends away from the light emitting direction. The base 3 is configured to extend from the end of the peripheral ring body 2 closer to the placement hole 11 and protrude relative to the outer periphery of the peripheral ring body 2. Because the first light-emitting surface 121 of the anti-glare lens transmits the outgoing light refracted by the first light-incident surface 13 out of the anti-glare lens, and the first light-emitting surface 121 has a honeycomb structure, the light transmitted through the first light-emitting surface 121 is uniformly dispersed, thereby achieving the effect of reducing or even preventing glare and thus avoiding damage to the human eye. In addition, the provision of the peripheral ring body 2 facilitates the accurate positioning of the lens body 1 relative to the light source and protects the lens body 1. The provision of the base 3 facilitates the provision of good positioning and sufficient support for the assembly of the anti-glare lens, thereby ensuring the reliable anti-glare performance of the anti-glare lens.

[0026] Please refer to Figure 1 、 Figure 4 and Figure 5 Preferably, the lens body 1 includes a reflective cup 15 having a reflective surface 151 proximal to the outer ring 2. The light-emitting surface 12 further includes a second light-emitting surface 122, which is disposed around the first light-emitting surface 121. The lens body 1 further includes a second light-entering surface 14 facing the placement hole 11. The second light-entering surface 14 is configured to refract incident light passing therethrough onto the reflective surface 151, and the reflective surface 151 is configured to reflect light emitted from the second light-entering surface 14 onto the second light-emitting surface 122. Therefore, the portion of incident light emitted by the light source and passing through the second light-entering surface 14 is reflected by the reflective surface 151 onto the second light-emitting surface 122, and then transmits out of the anti-glare lens. Thereby, the setting of the reflecting surface is improved, so that another part of the light emitted by the light source can be emitted through the second light-emitting surface 122. Since the apertures of the first light-emitting surface 121 and the second light-emitting surface 122 are increased successively, the light emitted from the first light-emitting surface 121 and the second light-emitting surface 122 can be superimposed on each other, thereby making the central light intensity of the anti-glare lens higher and the quality of the formed light spot better.

[0027] Please refer to Figure 4 and Figure 5Preferably, the reflective surface 151 is configured as a rhombus structure. In this way, the rhombus structure has a good light mixing effect on the light passing through it, thereby making the mixed light more uniform and softer when it is emitted through the refractive surface of the second light emitting surface 122, thereby reducing glare.

[0028] Please refer to Figure 1 and Figure 2 Preferably, the second light emitting surface 122 is set as a bevel, so that the part of the light passing through the second light incident surface 14 can be better refracted onto the reflecting surface 151, thereby reducing the formation of secondary light and achieving the effect of reducing glare.

[0029] Please refer to Figure 1 and Figure 4 Preferably, the reflective cup 15 is configured to be trumpet-shaped. Thus, the reflective cup 15 has a function of reflecting light toward the second light-emitting surface 122 .

[0030] Please refer to Figure 1 and Figure 2 Preferably, the outer ring body 2 and the surface facing the reflective surface 151 are provided with a light absorbing layer 21. Therefore, even if a small amount of light is emitted from the imperfect reflective surface 151, the light absorbing layer 21 can absorb the emitted light and prevent the emitted light from leaking through the side of the outer ring body 2.

[0031] Please refer to Figure 1 Preferably, the first light incident surface 13 is configured as a convex surface protruding toward the placement hole 11, and the first light emitting surface 121 is configured as a convex surface protruding toward the placement hole 11, and the curvature of the first light incident surface 13 is greater than the curvature of the first light emitting surface 121. In this way, through the coordination of the first light incident surface 13 and the first light emitting surface 121 with different curvatures, the first light incident surface 13 has a good light collecting effect, while the first light emitting surface 121 has a high light focusing and mixing effect, so that the central light intensity of the anti-glare lens is high and the formed light spot quality is good.

[0032] Please refer to Figure 3 Preferably, the top edges of the outer sides of the base 3 are formed into a rounded rectangle. In this way, the bottom of the anti-glare lens has a larger support surface, which is conducive to obtaining a stable support force. The rectangular base 3 is particularly conducive to assembly with the lamp holder.

[0033] Please refer to Figure 1 Preferably, the lens body 1 and the peripheral ring body 2 are both set to symmetrical structures, the symmetry center line of the lens body 1 coincides with the symmetry center line of the first light incident surface 13, and in the extension direction of the symmetry center line of the lens body 1, the end face of the base 3 exceeds the bottom surface of the placement hole 11. Therefore, there is a distance between the end face and the bottom surface of the hole, which is conducive to the light source being well positioned and arranged in the placement hole 11 to avoid interference.

[0034] As another object of the present invention, the present invention further provides a lamp comprising a light source (not shown), a lamp holder (not shown), and any of the above-described anti-glare lenses. A placement hole 11 houses the light source, and a base 3 is fixedly connected to the lamp holder. Thus, the lamp has a compact overall structure, is easy to assemble, and is highly reliable. The lamp can achieve the beneficial effects of any of the anti-glare lenses, which will not be further described herein. Thus, the lamp has the advantage of reducing or even preventing glare, thereby preventing damage to the human eye.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
