Description

Technical Field

[0001] This utility model belongs to the field of optical lens technology, and specifically relates to a dual-polarizing optical lens. Background Technology

[0002] A lens is an optical element made of a transparent material with a surface that is part of a sphere. However, lenses in the current technology can only achieve either a wall-washing function or a light-focusing projection function.

[0003] In view of this, the present invention aims to provide a dual-polarized optical lens, which can achieve dual polarization through ingenious structural design. One part of the light is reflected to the face of the person through a mirror, which improves the shortcomings of traditional spotlights that are prone to shadows, while the other part is directly focused and emitted, so that one lens can achieve two functions. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned deficiencies in the prior art by providing a dual-polarized optical lens. Through a clever structural design, it can achieve dual polarization. One part of the light is reflected onto the face via a mirror, improving the shortcomings of traditional spotlights that are prone to casting shadows. The other part is directly focused and emitted, thus enabling one lens to achieve two functions.

[0005] To overcome the aforementioned deficiencies in the prior art, the technical solution provided by this utility model is as follows:

[0006] A dual-polarized optical lens includes a lens body, a light-incident cavity for accommodating an LED lamp and being concave at the bottom of the lens body, a smooth and continuous arc-shaped reflective surface on the side of the lens body, a light-emitting surface on the top surface of the lens body, and a light-incident cavity including a bottom wall and a side wall, the bottom wall being arc-shaped, and the height of the side wall gradually decreasing from one side to the other.

[0007] As an improvement of the dual-polarized optical lens of this utility model, a plurality of compound eye structures are provided on the light-emitting surface.

[0008] As an improvement of the dual-polarized optical lens of this utility model, with the light-emitting surface as the top and the light-entry cavity as the bottom, the arc-shaped reflective surface gradually extends outward from bottom to top.

[0009] As an improvement of the dual-polarized optical lens of this utility model, the arc-shaped reflecting surface located on the side of the lens body is a free curvature reflecting surface and is arranged in a non-axially symmetrical manner.

[0010] As an improvement of the dual-polarized optical lens of this utility model, an installation notch is formed at the edge of the light-emitting surface.

[0011] As an improvement to the dual-polarized optical lens of this invention, when used in conjunction with a mirror, the lower sidewall is positioned closer to the mirror.

[0012] As an improvement of the dual-polarized optical lens of this utility model, with the light-emitting surface as the upper part and the light-entry cavity as the lower part, the arc surface of the bottom wall is a concave arc surface.

[0013] Compared with existing technologies, the dual-polarized optical lens provided by this utility model can achieve dual polarization through ingenious structural design. One part of the light is reflected to the face through a mirror, which has the function of supplementing light and improving the shortcomings of traditional spotlights that are prone to shadows. The other part is directly focused and emitted, so one lens can achieve two functions, and the light spot is uniform and soft. Attached Figure Description

[0014] The present invention and its beneficial technical effects will be further described in detail below with reference to the accompanying drawings and specific embodiments, wherein:

[0015] Figure 1 This is a top view of the present invention.

[0016] Figure 2 This is one of the structural schematic diagrams of this utility model when used in conjunction with a mirror.

[0017] Figure 3 This is the second structural schematic diagram of the present invention when used in conjunction with a mirror. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] like Figures 1-3As shown, this utility model provides a dual-polarizing optical lens, including a lens body 1. The bottom of the lens body 1 has a recessed light-entry cavity 11 for accommodating an LED lamp. The side surface of the lens body 1 is a smooth, continuous arc-shaped reflective surface 12, and the top surface of the lens body 1 is a light-exiting surface 13. The light-entry cavity 11 includes a bottom wall 111 and a side wall 112. The bottom wall 111 is arc-shaped, and the height of the side wall 112 gradually decreases from one side to the other. With the light-exiting surface above and the light-entry cavity below, the arc surface of the bottom wall 111 is a concave arc surface.

[0021] In the diagram, L1 and L2 represent the heights of the two sides, where L1 must be greater than L2. In this incident light area, a curved polarizing design enhances the intensity of the light reflected from the mirror. When used with a mirror, the lower sidewall 112 is positioned closer to the mirror. During use, both the light spot reflected by the mirror and the directly projected light spot are uniform, giving this invention both the optical effects of wall washing and focused light projection.

[0022] The light-emitting surface 13 is provided with a plurality of compound eye structures 14. The light finally passes through the compound eye structures 14 on the lens surface to enhance the homogenization effect, further improving the uniformity and softness of the light.

[0023] With the light-emitting surface 13 at the top and the light-entry cavity 11 at the bottom, the arc-shaped reflective surface 12 gradually extends outward from bottom to top. The arc-shaped reflective surface 12 located on the side of the lens body 1 is a free curvature reflective surface and is arranged in an asymmetrical manner (the left and right reflective surfaces are asymmetrically arranged). Through this asymmetrical curved surface design, light is reflected by the mirror onto the person's face, which has the effect of supplementary lighting and improves the shortcomings of traditional spotlights that are prone to shadows.

[0024] The edge of the light-emitting surface 13 has an installation notch 15, which facilitates the stable installation of the lens on the front light later.

[0025] In this invention, dual polarization and single polarization refer to... Figure 2 The light reflected from the curved reflective surface 12 and the light-emitting surface 13 onto the mirror, and then reflected again by the mirror to form polarized light, achieves the effect of supplementary lighting. The other polarization refers to… Figure 3 The light entering through the light-incident cavity 11, refracted through the curved bottom wall 111, and then emitted from the light-exiting surface 13, is polarized light formed by reflection again through a mirror. Another layer of light is the light directly projected through the curved reflecting surface 12 and the light-exiting surface 13 (such as...). Figure 2 As shown), the light spots above can all form uniform light spots after being homogenized by the compound eye structure 14.

[0026] Although 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 alterations can be made to these embodiments without departing from the principles and structure of the present invention, the scope of which is defined by the appended claims and their equivalents.
