Description

Technical Field

[0001] The utility model belongs to the technical field of light guide plate manufacturing, and particularly relates to an adaptive dimming light guide plate. Background Art

[0002] A light guide plate is an efficient optical component that guides light to be evenly distributed through an internal microstructure to achieve a surface light source effect. It is usually made of materials with high light transmittance, such as acrylic or PC, and is internally designed with fine dots, grooves or textures to control the light propagation path. The light guide plate is widely used in backlight modules, such as liquid crystal displays, advertising light boxes, etc., which can effectively improve the light efficiency, reduce costs, and exhibit uniform and soft light, providing important support for modern display technologies.

[0003] In traditional lighting systems, the light guide plate usually consists of two glass substrates, and a light scattering material is filled between the two substrates. However, this traditional method has some deficiencies, such as poor light scattering effect, large installation errors, and high light loss during propagation, resulting in uneven lighting effects and low lighting efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an adaptive dimming light guide plate to solve the problems of poor light scattering effect and uneven lighting effect of common light guide plates.

[0005] The utility model realizes the above purpose through the following technical solutions: it includes two glass substrates, connection sleeves are fixedly arranged inside the four corners of the two glass substrates, a light scattering component is arranged between the two glass substrates, the light scattering component includes a first splicing box and a second splicing box, a plurality of conical grooves are arranged on the surfaces of the first splicing box and the second splicing box, connection posts are fixedly arranged at the four corners inside the first splicing box and the second splicing box, the light scattering component further includes four strip-shaped reflectors, and the reflectors are clamped by the connection posts.

[0006] Further, two adjacent connection posts are positioned and connected through insertion posts and insertion slots.

[0007] Further, four limiting strips are fixedly arranged on the inner surface of the glass substrate, and the first splicing box and the second splicing box are clamped inside the four limiting strips.

[0008] Further, the two glass substrates are connected by screws passing through the connection sleeves.

[0009] Further, the partial volume of the conical grooves forms a hollow cone on the inner surfaces of the first splicing box and the second splicing box.

[0010] Beneficial effects: The design of the present utility model is reasonable and has the following beneficial effects:

[0011] 1. In the solution of the present utility model, when light passes through the glass substrate and enters the light scattering component, it undergoes the first diffuse reflection in the conical groove on the surface of the splicing box. The conical groove and the two surfaces of the hollow cone undergo two refractions in total, and four refractions will occur in two splicing boxes, which can adjust the light into a gentle diffuse reflection light, adapt to the vast majority of light, and avoid direct strong light.

[0012] 2. In the solution of the present utility model, the reflecting mirror in the light scattering component can reflect the light that diverges in all directions after refraction back to the hollow cone and re-direct it out, avoiding a significant reduction in the illumination amount affected by refraction and affecting the illumination effect.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments.

[0018] Combined with Figures 1 to 2 As shown in an adaptive dimming light guide plate, it includes two glass substrates 1. Connecting sleeves 2 are fixedly provided on the inner sides of the four corners of the two glass substrates 1. A light scattering component 3 is provided between the two glass substrates 1. The light scattering component 3 includes a first splicing box 31 and a second splicing box 32. A plurality of conical grooves 33 are provided on the surfaces of the first splicing box 31 and the second splicing box 32. Connecting piles 34 are fixedly provided at the four corners inside the first splicing box 31 and the second splicing box 32. The light scattering component 3 further includes four strip-shaped reflecting mirrors 35, and the reflecting mirrors 35 are clamped by the connecting piles 34.

[0019] Among them, two adjacent connecting piles 34 are positioned and connected through a plug post and a plug slot. Through the positioning connection of the plug post and the plug slot, the precise alignment between the components inside the light scattering component 3 is ensured, and the poor light scattering effect caused by installation errors is avoided.

[0020] Four limit bars 4 are fixedly provided on the inner surface of the glass substrate 1. The first splicing box 31 and the second splicing box 32 are inserted into the inner sides of the four limit bars 4. The limit bars 4 provide a stable support for the light scattering component 3, preventing it from shaking or shifting between the glass substrates 1, thereby ensuring the stability of the light scattering effect.

[0021] The two glass substrates 1 are connected after being screwed through the connecting sleeve 2, thereby enhancing the structural strength of the entire light guide plate and ensuring stability in long-term use.

[0022] Part of the volume of the conical groove 33 forms a hollow cone 36 on the inner surfaces of the first splicing box 31 and the second splicing box 32. The combination of the conical groove 33 and the hollow cone 36 further enhances the diffuse reflection effect of the light, making the light softer and more uniform after multiple refractions and reflections inside the light guide plate. At the same time, the design of the hollow cone 36 effectively reduces the loss of light during the propagation process, improves the lighting efficiency, and enables the light guide plate to provide brighter and more uniform lighting effects under the same light source.

[0023] Working principle: When the utility model is in use, when the light passes through the glass substrate and enters the light scattering component, it undergoes the first diffuse reflection at the conical groove on the surface of the splicing box. The conical groove and the two surfaces of the hollow cone experience two refractions in total. The two splicing boxes will undergo four refractions, which can adjust the light into a flat diffuse reflected light and then pass through the glass substrate on the other side and emit it. After refraction, the light scattered in all directions is reflected by the reflector back to the hollow cone and redirected and emitted, avoiding a significant reduction in the amount of lighting due to refraction.
