Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of light guide plate structures, and in particular relates to a waterproof light guide plate and an optical device. Background Art
[0002] The light guide plate is made of optical grade acrylic / PC sheet, and then uses high-tech materials with extremely high refractive index and non-light absorption to print light guide points on the bottom of the optical grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.
[0003] Light guide plates are widely used due to their small thickness, beautiful appearance and energy saving. Due to people's pursuit of entertainment life, light guide plates may appear in various application scenarios, which requires the diversification of light guide plate functions. Among them, waterproof function is one of the more important functions, but the waterproof performance of existing light guide plates cannot meet the needs of increasingly rich scene usage. Therefore, it is urgent to propose a new technical solution to solve the above problems. Utility Model Content
[0004] One of the purposes of the utility model is to provide a waterproof light guide plate to address the deficiencies of the prior art, which increases the waterproof performance of the light guide plate by providing a waterproof film and a waterproof member.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A waterproof light guide plate comprises a light guide plate layer, both sides of which are provided with photosensitive adhesive layers, a waterproof film is provided on one side of each photosensitive adhesive layer away from the light guide plate layer, a plurality of convex strips extend from the surface of the photosensitive adhesive layer away from the light guide plate layer, the convex strips and the waterproof film form a containing space, and the containing space is used to place waterproof components.
[0007] In actual application, the light guide plate layer, the photosensitive adhesive layer, the waterproof film and the waterproof component are all configured as transparent structures, which can ensure that the photosensitive adhesive layer is fixed to the light guide plate layer while ensuring the basic functions of the light guide plate are realized. The photosensitive adhesive layer and the convex strips can also increase the anti-extrusion ability of the light guide plate.
[0008] As an improvement of the waterproof light guide plate described in the utility model, the plurality of convex strips are arranged in the same direction, the accommodating space is configured as a strip structure, and the waterproof component is configured as a waterproof rubber strip matching the accommodating space.
[0009] As an improvement of the waterproof light guide plate described in the utility model, the convex strips include a first strip and a second strip, a plurality of the first strips and a plurality of the second strips are arranged in different directions respectively, and the first strips and the second strips are arranged crosswise.
[0010] As an improvement of the waterproof light guide plate described in the utility model, the accommodating space is configured as a block structure, and the waterproof component is a waterproof rubber block matching the accommodating space.
[0011] As an improvement of the waterproof light guide plate described in the utility model, one end of the convex strip close to the photosensitive adhesive layer is the bottom end, the end of the convex strip opposite to the bottom end is the top end, and the convex strip is arranged as a triangular prism structure with a large bottom end and a small top end.
[0012] As an improvement of the waterproof light guide plate described in the utility model, in the thickness direction of the light guide plate, the thickness of the convex strip is H1, 4μm≤H1≤14μm, and the thickness of the photosensitive adhesive layer is H2, 11μm≤H2≤19μm.

[0013] As an improvement of the waterproof light guide plate described in the utility model, the light guide plate layer includes a plate body, a diffuser plate and a reflector plate. The diffuser plate and the reflector plate are respectively arranged on two sides of the plate body in the thickness direction. The diffuser plate can atomize the direct light coming out of the light guide plate and disperse it evenly.

The focusing plate can aggregate the light source to increase the brightness.
