Description

Technical Field

[0001] This utility model relates to the field of optical accessories technology in the lighting industry, specifically to an electroplated anti-glare lens. Background Technology

[0002] In the lighting field, the anti-glare index is increasingly becoming an important optical indicator for luminaires, and engineers have adopted various methods to reduce glare and achieve a smaller UGR (Ultra-Glare Ratio). These methods either improve the optical design of optical components or improve the luminaire structure or add optical components. These methods can reduce glare, but some glare still exists.

[0003] Due to limitations in size and structure, lenses sometimes receive some light on their bottom surface. Alternatively, due to temperature limitations, heat dissipation holes are designed on the bottom surface of the lens to address heat dissipation, or the bottom surface is suspended at a certain height to facilitate heat dissipation. These designs or methods all result in light entering through the heat dissipation holes or the bottom surface of the lens. Because of the limited incident area, this light generally forms a noticeable residual light layer or stray light. Only by addressing this portion of light can the anti-glare effect be improved. Therefore, to avoid the shortcomings of existing technologies, it is necessary to improve them. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide an electroplated anti-glare lens with a simple structure and reduced glare.

[0005] This utility model is achieved through the following technical solution:

[0006] An electroplated anti-glare lens includes a lens body, a light-emitting surface at the top of the lens body, a light-entry hole at the bottom of the lens body, a lens bottom surface at the bottom of the lens body, a heat dissipation hole on the side of the light-entry hole, and an electroplated surface on the lens bottom surface or the wall of the heat dissipation hole.

[0007] Furthermore, the electroplated surface is an electroplated bright silver surface.

[0008] Furthermore, the electroplated surface is an electroplated black surface.

[0009] Furthermore, the electroplated surface is a light-absorbing surface.

[0010] Furthermore, the electroplated surface is a reflective surface.

[0011] Furthermore, the heat dissipation hole has an opening at the bottom.

[0012] Furthermore, a total reflection surface is provided on the outer side of the lens body.

[0013] Furthermore, the light inlet hole is provided with a light inlet hole sidewall surface and a light inlet hole top surface.

[0014] Furthermore, the top surface of the light inlet aperture is convex arc-shaped, and the light outlet surface is planar.

[0015] Furthermore, the light inlet aperture is designed to gradually decrease in size from bottom to top.

[0016] Compared to existing technologies, this invention features an electroplated surface on the bottom surface of the lens or the wall of the heat dissipation hole. The electroplated surface serves to reflect or absorb light. When the electroplated surface reflects light, the light is reflected onto the light source, the light source support, or the optical accessories, thereby eliminating glare. When the electroplated surface absorbs light, stray light is absorbed, thereby eliminating glare and reducing glare, resulting in a better anti-glare effect. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 2 The present invention discloses an electroplated anti-glare lens, comprising a lens body 1, a light-emitting surface 2 at the top of the lens body 1, a light-entry hole at the bottom of the lens body 1, a lens bottom surface 3 at the bottom of the lens body 1, a heat dissipation hole 4 on the side of the light-entry hole, and an electroplated surface on the wall of the lens bottom surface 3 or the heat dissipation hole 4. The electroplated surface serves to either reflect or absorb light. When the electroplated surface reflects light, the light is reflected onto the light source, the light source support, or the optical accessories, thereby eliminating glare. When the electroplated surface absorbs light, stray light is absorbed, thereby eliminating or reducing glare, resulting in a better anti-glare effect.

[0032] The electroplated surface is a bright silver plating surface that reflects light.

[0033] The electroplated surface is black, and it absorbs light.

[0034] The electroplated surface is a light-absorbing surface, reflecting light.

[0035] The electroplated surface is reflective, absorbing light.

[0036] The bottom opening of heat dissipation hole 4 facilitates heat dissipation of the light source.

[0037] The outer side of the lens body 1 is provided with a total reflection surface 5, which reflects the light incident into the lens body 1, resulting in more uniform light emission.

[0038] The light entrance aperture has a side wall surface 6 and a top surface 7, which refract the incident light, control the outgoing direction of the light, and reduce glare.

[0039] The top surface 7 of the light inlet is convex, while the light outlet 2 is flat, resulting in more concentrated and uniform emitted light.

[0040] The light entrance aperture is set to gradually decrease in size from bottom to top, refracting the incident light onto the total reflection surface. After being fully reflected by the total reflection surface, the emitted light has a wide range and uniform light emission.

[0041] like Figure 3 As shown, the bottom surface 3 of the lens is attached to the light source support. When the bottom surface 3 of the lens is transparent, some light will enter from this point, ultimately forming glare outside the light spot; as... Figure 4 As shown, when a bright silver reflective layer is electroplated onto the bottom surface 3 of the lens, light will be reflected back to the light source, thus eliminating glare; as Figure 5 As shown, when the bottom surface 3 of the lens is electroplated with a black coating, the light will be absorbed, thereby eliminating glare.

[0042] like Figure 6 As shown, the lens has a heat dissipation hole 4. When the wall of the heat dissipation hole 4 is transparent, some light will enter through this hole, ultimately forming glare outside the light spot; as... Figure 7 As shown, when a bright silver reflective layer is electroplated onto the heat dissipation hole 4, light will be reflected and ultimately reflected outside the optical components, where it will be absorbed by the lamp's internal cavity, thus eliminating glare; as Figure 8 As shown, when the heat dissipation hole 4 is electroplated with a black coating, the light will be absorbed, thereby eliminating glare.

[0043] like Figure 9 As shown, the bottom surface 3 of the lens is suspended above the light source support or the light source. When the bottom surface 3 of the lens is transparent, some light will enter from this point, ultimately forming glare outside the light spot; as... Figure 10 As shown, when a bright silver reflective layer is electroplated onto the bottom surface 3 of the lens, light will be reflected by it, ultimately reflected onto the light source support or outside the optical components, and finally absorbed, thus eliminating glare; as Figure 11 As shown, when the bottom surface 3 of the lens is electroplated with a black coating, the light will be absorbed, thereby eliminating glare.

[0044] The bottom surface of the lens 3 or the heat dissipation hole 4 is electroplated with bright silver, which eliminates glare through reflection.

[0045] The bottom surface of the lens (3) or the heat dissipation hole (4) is electroplated black, which absorbs and eliminates glare.

[0046] The method to reduce glare is to electroplate or cover the surfaces where glare is generated: the surfaces that need to be electroplated are not only the bottom surface and heat dissipation holes, but also the other surfaces, as long as glare exists, and the glare can be eliminated by reflection or absorption through the coating.

[0047] Methods for applying a coating: This can be electroplating or other methods, such as screen printing.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
