Technical Field
[0001] The utility model belongs to the technical field of optical lenses, and particularly relates to a large-angle polarized strip lamp lens. Background Art
[0002] At present, most refrigerator lamps in the market are arranged in a combination of single lenses. The polarization is relatively low and small, there is more peripheral light on the outside, the light efficiency is not high, and the uniformity is also relatively low.
[0003] In view of this, the utility model aims to provide a large-angle polarized strip lamp lens, which can make the light have a large polarization angle, have a high uniformity at the same time, and use a strip lamp design, which can make the arrangement of LEDs more free and flexible. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a large-angle polarized strip lamp lens for the above-mentioned defects of the prior art, which can make the light have a large polarization angle, have a high uniformity at the same time, and use a strip lamp design, which can make the arrangement of LEDs more free and flexible.
[0005] In order to solve the above-mentioned defects of the prior art, the technical solution provided by the utility model is as follows:
[0006] A large-angle polarized strip lamp lens includes a strip lens main body. The bottom of the strip lens main body is set as an arc-shaped light incident surface, the top of the strip lens main body is a light exit surface, and one side of the strip lens main body is provided with a reflective arc-shaped concave surface; light enters from the light incident surface, is reflected by the reflective arc-shaped concave surface, and finally exits from the light exit surface.
[0007] As an improvement of the large-angle polarized strip lamp lens of the utility model, the other side of the strip lens main body is a flat outer wall.
[0008] As an improvement of the large-angle polarized strip lamp lens of the utility model, the reflective arc-shaped concave surface does not need electroplating, and the arc surface vertical surface < 90 degrees. On the one hand, it has a better reflection distance, and on the other hand, it is easier to demold for the mold structure.
[0009] As an improvement of the large-angle polarized strip lamp lens of the utility model, the bottom of the strip lens main body bulges outwards towards the side where the reflective arc-shaped concave surface is located to form a first installation groove.
[0010] As an improvement of the large-angle polarized strip lamp lens of the utility model, a second installation groove is formed on the side of the bottom of the strip lens main body away from the reflective arc-shaped concave surface.
[0011] As an improvement of the large-angle polarized strip lamp lens of the utility model, the opening directions of the first installation groove and the second installation groove are perpendicular to each other.
[0012] As an improvement of the large-angle polarized strip lamp lens of the present utility model, the light-emitting surface is arc-shaped, and the bending degree of the light-incident surface is greater than that of the light-emitting surface.
[0013] Compared with the prior art, through the ingenious structural design of the present utility model, the light can have a relatively large polarization angle, and at the same time, have a high uniformity. In addition, the strip lamp design allows the arrangement of LEDs to be more free and flexible. Moreover, the design of the reflective arc-shaped concave surface enables the light that was originally difficult to utilize to be reflected back to the main light spot area, which can effectively reduce the peripheral light and increase the efficiency.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.
[0022] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0023] As Figures 1 to 5 shown, a large-angle polarized strip light lens provided by the present utility model includes a strip lens body 1. The bottom of the strip lens body 1 is provided with an arc-shaped light incident surface 11, the top of the strip lens body 1 is a light exit surface 12, and a reflecting arc-shaped concave surface 13 is provided on one side of the strip lens body 1; light enters from the light incident surface 11, is reflected by the reflecting arc-shaped concave surface 13, and finally exits from the light exit surface 12. This design enables the light that was originally difficult to utilize to be reflected back to the main light spot area, which can effectively reduce the peripheral light on the outside and increase the efficiency.
[0024] The other side of the strip lens body 1 is a flat outer wall, and basically no light passes through this side.
[0025] The reflecting arc-shaped concave surface 13 does not need to be electroplated, and the arc surface vertical surface is < 90 degrees. On the one hand, it has a better reflection distance, and on the other hand, it is easier to demold for the mold structure.
[0026] The bottom of the strip lens body 1 bulges outward toward the side where the reflecting arc-shaped concave surface 13 is located to form a first installation groove 14. The side of the bottom of the strip lens body 1 away from the reflecting arc-shaped concave surface 13 forms a second installation groove 15. The opening directions of the first installation groove 14 and the second installation groove 15 are perpendicular to each other, which is convenient for installing the entire lens on the light source.
[0027] The light exit surface 12 is arc-shaped, and the bending degree of the light incident surface 11 is greater than that of the light exit surface 12. The light entering the strip lens body 1 through the light incident surface 11 is refracted by the light exit surface 12 and then exits.
[0028] Through the ingenious structural design, the present utility model can enable the light to have a large polarization angle, and at the same time have a high uniformity. And with the strip light design, the arrangement of the LEDs can be more free and flexible.
[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and structure of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalent scope.
