[0002] In recent years, based on the characteristics of energy saving, environmental protection, high efficiency, small size and long life, LED light strip structures have become more and more popular among consumers. Replacing traditional incandescent lamps and fluorescent lamps has become a trend. LED light strips are widely used in lighting in various occasions, especially indoor lighting. LED light strips can be seen everywhere. The LED light strip structure includes a substrate and a number of LED lamp beads arranged on the substrate.
[0003] However, with the continuous improvement of people's living standards, people's performance requirements for LED light strips are getting higher and higher.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0033] Such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown in the figure, a polarized light strip lamp lens structure includes a lens mounting main body and a lens outer seat 1. The lens mounting main body and the lens outer seat 1 are integrally formed. The lens mounting main body includes a lens mounting base 2 and a polarized light lens main body 3. The lens outer seats 1 are symmetrically arranged at both ends of the lens mounting base 2. The inner surface of the lens outer seat 1 is provided with a striped surface 4 and a plurality of snap connection seats 5. The outer surface of the lens mounting base 2 is provided with a light homogenizing surface 6. The inner surface of the lens mounting base 2 is connected to the polarized light lens main body 3. The bottom of the polarized light lens main body 3 is provided with a first polarization part 7 and a second polarization part 8. An installation recess 9 for accommodating the lamp beads is formed by enclosing between the first polarization part 7, the second polarization part 8 and the bottom of the polarized light lens main body 3. A working area is provided on the polarized light lens main body 3, and the beam angle range of the working area can be from 10° to 30°, preferably from 25° to 30°. After the light emitted by the lamp beads penetrates the polarized light lens main body 3, it then passes through the light homogenizing surface 6 and irradiates outward.
[0034] It should be noted that by setting the polarized light lens main body 3 in the present invention, the light emitted by the lamp beads has a polarized light effect. Therefore, when the present invention is used in cooperation with a lamp, it has the advantages of reducing eye fatigue, improving image quality and vivid colors, and having a long service life.
[0035] As Figure 2 shown, the light homogenizing surface 6 is a bead surface, which can homogenize the light.
[0036] It should be noted that the principle of light homogenization when light passes through the bead surface: when light passes through the bead surface, due to the high reflectivity of the inner wall of the bead surface, the light is reflected multiple times on the inner wall of the bead surface instead of directly emitting out. This process of multiple reflections and diffuse reflections ensures that the distribution of light on the inner wall of the bead surface is more uniform, thus achieving the effect of light homogenization.
[0037] As Figure 5 shown, the material of the polarized light lens main body 3 is PMMA material, and the PMMA material has characteristics such as high light transmittance, good light resistance, easy processing, good mechanical properties, low hygroscopicity, and recyclability.
[0038] As Figure 3 and Figure 4 shown, the first polarization part 7 is provided with a first incident surface 10, a first refraction surface 11 and a first reflection surface 12. Part of the light emitted by the lamp beads is refracted after passing through the first incident surface 10 and the first reflection surface 12 in sequence, so that the light penetrates the polarized light lens main body 3 and the light homogenizing surface 6 along the first refraction surface 11 and irradiates outward.
[0039] As Figure 3 and Figure 4As shown, a second incident surface 13, a second refraction surface 14, and a second reflection surface 15 are provided on the second polarization part 8. Part of the light emitted by the lamp bead passes through the second incident surface 13 and the second reflection surface 15 in sequence and then undergoes refraction, so that the light irradiates outward along the second refraction surface 14 through the polarization lens body 3 and the light homogenizing surface 6.
[0040] As Figure 3 and Figure 4 shown, the slope of the first reflection surface 12 is greater than the slope of the second reflection surface 15.
[0041] It should be noted that, with the cooperation of the first polarization part 7, the second polarization part 8, and the polarization lens body 3, the light emitted by the lamp bead achieves a polarization effect: part of the light of the lamp bead passes through the first incident surface 10 and the first reflection surface 12 in sequence and then undergoes refraction, so that the light irradiates outward along the first refraction surface 11 through the polarization lens body 3 and the light homogenizing surface 6; the second part of the light of the lamp bead passes through the second incident surface 13 and the second reflection surface 15 in sequence and then undergoes refraction, so that the light irradiates outward along the second refraction surface 14 through the polarization lens body 3 and the light homogenizing surface 6; the third part of the light of the lamp bead directly passes through the polarization lens body 3 and the light homogenizing surface 6 and shoots outwards.
[0042] As Figure 4 and Figure 5 shown, support seats 16 are symmetrically arranged on the inner surface of the lens mounting base 2. The polarization lens body 3 is located between the two support seats 16. A plurality of protruding buffer parts 17, a plurality of protruding plug-in parts 18, and a plurality of plug-in concave parts 19 are provided at the bottom of the support seats 16.
[0043] As Figure 4 and Figure 5 shown, the lens outer seat 1 is in an "L" shape and includes a horizontal part 20 and a vertical part 21. One end of the horizontal part 20 is connected to the lens mounting base 2, and the other end is connected to the vertical part 21. The horizontal part 20 and the vertical part 21 are integrally formed.
[0044] As Figure 4 and Figure 5 shown, a part of the stripe surface 4 is located on the inner surface of the horizontal part 20, and another part of the stripe surface 4 is located on the inner surface of the vertical part 21.
[0045] As Figure 5 shown, the snap connection seat 5 is arranged on the inner surface of the vertical part 21 and is located below the stripe surface 4. A plurality of snap connection parts 22 and a plurality of snap connection grooves 23 are provided on the snap connection seat 5. The snap connection seat 5 is convenient for installation with the housing and is convenient for disassembly for replacement or maintenance.
[0046] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and the above description; however, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and variations of the above embodiments made according to the substantial technology of the present utility model are still within the technical solution of the present utility model.
