Side light-emitting anti-dazzle lens

Abstract

The utility model relates to a side light emitting anti-dazzle lens, which comprises a light incident surface, a first refracting surface, a second refracting surface and a light emitting surface, the light incident surface is arranged in the middle of the lens, the first refracting surface is arranged around the light incident surface in a horn cylinder shape, the light emitting surface is vertically arranged above the side of the light incident surface, and the second refracting surface is arranged above the light emitting surface. The second refracting face is obliquely located above the other side of the light-in face, and the second refracting face and the light-out face are arranged in an inclined angle mode. Light enters from the light-in surface, is guided by the cylindrical first refracting surface, is deflected by the second refracting surface which is obliquely arranged, and finally is emitted out from the position over the light-out surface at a proper angle. In the process, light rays are effectively prevented from being directly emitted from the lower portion of the light source, the glare problem caused by direct refraction is reduced, and the visual comfort degree is greatly improved.

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the side-emitting anti-glare lens of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0015] See also Figures 1 to 3 The side-light anti-glare lens of an embodiment of the utility model comprises a light incident surface 1, a first refractive surface 2, a second refractive surface 3 and a light emitting surface 4, wherein the light incident surface 1 is arranged in the middle of the lens, the first refractive surface 2 is arranged around the light incident surface 1 in a trumpet-cylindrical shape, the light emitting surface 4 is vertically located above the side of the light incident surface 1, the second refractive surface 3 is obliquely located above the other side of the light incident surface 1, and the second refractive surface 3 and the light emitting surface 4 are arranged at an inclined angle.

[0016] In the above embodiment, the light enters from the light incident surface 1, is first guided by the first refractive surface 2 of the horn cylinder, and then deflected by the second refractive surface 3 set at an angle, and finally the light is emitted from directly above the light emitting surface 4 at a suitable angle. This process effectively avoids the light from being emitted directly from below the light source, reduces the glare problem caused by direct refraction, and greatly improves the visual comfort. When using it, the user can feel the soft light even if looking directly at the light emitting surface 4, avoiding glare and discomfort, and achieving a true anti-glare effect.

[0017] See also Figures 1 to 3 In another embodiment, the light incident surface 1 includes a side light incident surface 11 and a front light incident surface 12 , the front light incident surface 12 is located in the middle of the lens, and the side light incident surface 11 is cylindrical and surrounds the front light incident surface 12 .

[0018] In the above embodiment, the front light incident surface 12 is located at the center of the lens to directly capture the front light, while the side light incident surface 11 surrounds it in a cylindrical layout, further widening the light receiving range. This design not only enhances the light collecting ability of the lens, but also makes the light distribution more uniform, helps to reduce the light blind spot, and improves the overall lighting effect.

[0019] See also Figures 1 to 3 In another embodiment, a plurality of microstructure surfaces are formed on the light emitting surface 4 .

[0020] In the above embodiment, the microstructure can effectively promote the scattering and mixing of light, ensure uniform mixing of white light during the light emission process, and eliminate the yellowing phenomenon at the edges.

[0021] See also Figures 1 to 3 In another embodiment, the angle between the second refractive surface 3 and the light emitting surface 4 is in the range of 40° to 30°.

[0022] In the above embodiment, the deflection angle behind the second refractive surface 3 can effectively prevent glare caused by direct light and enable the light to be emitted from the light emitting surface 4 in a softer and more uniform manner.

[0023] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
