Description

Technical Field

[0001] This utility model belongs to the field of lens technology, and specifically relates to a saddle-shaped bipolar lens. Background Technology

[0002] A lens is an important optical element whose core function is to achieve imaging, focusing, or light transmission by refracting light.

[0003] In the field of lenses, in order to achieve a special light pattern, it is necessary to divide the light spot into two paths and achieve different polarization angles on both sides.

[0004] Large-angle polarized street light lenses are mainly used for road lighting. Their focusing angle is usually between 100 and 120 degrees to meet the optical needs of different scenarios such as main roads and branch roads.

[0005] In view of this, the present invention aims to provide a saddle-shaped bipolar lens, which, through ingenious structural design, employs an asymmetrical saddle-shaped optical surface. By adjusting the height and curvature of the saddle-shaped double peaks, it controls the effect of different polarization angles. Simultaneously, by combining it with barrier structures of different shapes at the front and rear, it optimizes and enhances the peak effect in the target area. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a saddle-shaped bipolar lens. Through ingenious structural design, it employs an asymmetrical saddle-shaped optical surface, adjusting the height and curvature of the saddle-shaped double peaks to control different polarization angles. Furthermore, it optimizes and enhances the peak effect in the target area by incorporating front and rear barrier structures of different shapes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A saddle-shaped bipolar lens includes a lens body, which includes an incident light surface and an exit light surface. The incident light surface is provided with an incident light hole for mounting an LED lamp. On both sides of the opening of the incident light hole, an asymmetrically arranged first reflection structure and a second reflection structure extend outward toward the side where the exit light surface is located.

[0008] As an improvement to the saddle-shaped bipolar lens of this utility model, the side of the first reflecting structure closest to the second reflecting structure is a surface with free curvature, and the side of the second reflecting structure closest to the first reflecting structure is also a surface with free curvature.

[0009] As an improvement of the saddle-shaped bipolar lens of this utility model, the curved surface of the first reflecting structure is a curved surface that is concave in the direction away from the second reflecting structure, and the curved surface of the second reflecting structure is a curved surface that is concave in the direction away from the first reflecting structure.

[0010] As an improvement to the saddle-shaped bipolar lens of this utility model, the width of the first reflective structure is greater than the width of the second reflective structure, and the height of the first reflective structure is greater than the height of the second reflective structure.

[0011] As an improvement to the saddle-shaped bipolar lens of this utility model, the acute angle formed by the outer wall of the first reflective structure and the horizontal plane is smaller than the acute angle formed by the outer wall of the second reflective structure and the horizontal plane.

[0012] As an improvement of the saddle-shaped bipolar lens of this utility model, both the light entrance aperture and the light exit surface are free curvature surfaces.

[0013] As an improvement of the saddle-shaped bipolar lens of this utility model, mounting blocks are formed at both ends of the incident surface, and mounting posts are provided on the mounting blocks.

[0014] Compared with the prior art, the present invention has at least the following advantages: First, by setting an asymmetrical first reflection structure and a second reflection structure, this utility model can achieve two light spots required for a special light pattern, and achieve different polarization angles on both sides, thus ensuring both optical effect and aesthetic effect.

[0015] Secondly, the asymmetric saddle-shaped optical surface of this invention can control the polarization angle effect by adjusting the height and curvature of the saddle-shaped double peaks.

[0016] Third, by combining different shaped retaining wall structures (first reflection structure and second reflection structure) at the front and rear, the peak effect of the target area is optimized and increased. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0027] like Figures 1-7 As shown, this utility model provides a saddle-shaped bipolar lens, including a lens body 1. The lens body 1 includes an incident surface 11 and an exiting surface 12. An incident aperture 13 for mounting an LED lamp 2 is provided on the incident surface 11. Asymmetrically arranged first and second reflection structures 3 and 4 extend outwards from the opening of the incident aperture 13 towards the side where the exiting surface 12 is located, thus forming an overall saddle-shaped structure. This utility model, by setting the asymmetrical first and second reflection structures 3 and 4, can achieve two light spots required for a specific light pattern and achieve different polarization angles on both sides, ensuring both optical performance and aesthetic appeal. Furthermore, the asymmetrical saddle-shaped optical surface of this utility model allows for control of the polarization angle by adjusting the height and curvature of the saddle-shaped double peaks (first reflection structure 3 and second reflection structure 4). In other words, this utility model, with its special saddle-shaped structure, can achieve different polarization angles on both sides. The side of the first reflecting structure 3 closest to the second reflecting structure 4 is a surface with free curvature, and the side of the second reflecting structure 4 closest to the first reflecting structure 3 is also a surface with free curvature. That is, this invention is an optical surface structure with asymmetric free curvature.

[0028] The surface of the first reflective structure 3 is concave in the direction away from the second reflective structure 4, and the surface of the second reflective structure 4 is also concave in the direction away from the first reflective structure 3. Furthermore, the width of the first reflective structure 3 is greater than the width of the second reflective structure 4, and the height of the first reflective structure 3 is greater than the height of the second reflective structure 4. The acute angle formed by the outer wall of the first reflective structure 3 and the horizontal plane is smaller than the acute angle formed by the outer wall of the second reflective structure 4 and the horizontal plane. These differences between the two reflective structures allow for different polarization angles on both sides. In practical use, the height, width, and curvature of the saddle-shaped double peaks (first reflective structure 3 and second reflective structure 4) can be adjusted to control the polarization angle effect according to the actual situation.

[0029] Both the light inlet aperture 13 and the light outlet surface 12 are free curvature surfaces.

[0030] Mounting blocks 5 are formed at both ends of the light-incident surface 11, and mounting posts 6 are provided on the mounting blocks 5 to facilitate the installation of the entire lens.

[0031] When using, such as Figure 7 As shown, after the light emitted by the LED lamp 2 in the light entrance hole 13 passes through the light entrance surface 11, part of it is refracted directly to both sides from the light exit surface 12, and the other part reaches the first reflection structure 3 and the second reflection structure 4. After reflection, it is emitted from both sides at different angles. The refracted light and the reflected light converge together to form the effect of different polarization angles on both sides. That is, this utility model optimizes and increases the peak effect of the target area by combining the barrier wall structures (first reflection structure and second reflection structure) with different shapes on the front and rear sides.

[0032] 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.
