[0001] The utility model relates to the technical field of light guide plates, in particular to a light guide plate with a frosted surface structure. Background Art

[0002] With the development of optical technology and the progress of the times, light guide plates have been widely used in many fields. Light guide plates are made of optical-grade acrylic / PC sheets and high-tech materials with extremely high refractive index and no light absorption.

[0003] When the existing light guide plate performs double-sided luminescence, the two light guide plates are often separately placed through a frame. However, the symmetrical placement of the two light guide plates is slow, thus affecting the working progress of the light guide plates. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem of the existing light guide plate, which often requires two light guide plates to be separately placed through a frame when performing double-sided lighting work, but the work process of symmetrically placing the two light guide plates is slow, thereby affecting the work progress of the light guide plates. A light guide plate with a frosted surface is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A light guide plate having a frosted surface, comprising:

[0007] A first light guide plate, the bottom end of the first light guide plate is connected to a first column, and a slot is provided on the inner side of the bottom end of the first column, a second light guide plate is arranged below the first light guide plate, and the top of the second light guide plate is connected with second columns on all sides, a plug-in column is welded on the top of the second column, and the plug-in column and the slot are plugged in, the outer walls of the first light guide plate and the second light guide plate are provided with reserved grooves, the first light guide plate and the second light guide plate both include a light guide plate body, and a diffuser is laid on the top of the light guide plate body, a reflector is arranged on the bottom end of the light guide plate body, and light guide points are printed on the bottom surface of the light guide plate body.

[0008] Preferably, the structure of the first light guide plate is consistent with that of the second light guide plate, and the first light guide plate forms a detachable structure through the first column, the slot, the plug-in column, the second column and the second light guide plate.

[0009] Preferably, the inner depth of the reserved groove is 1 mm.

[0010] Preferably, through holes matching the first columns are provided on the inner side of the reflective sheet, and the first columns are distributed in two groups.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0012] 1. In the present invention, by setting the first column, the slot, the plug-in column, the second column, etc., people can first perform a splicing operation on the first light guide plate and the second light guide plate, and then perform the installation work between them after they are symmetrically distributed. This can effectively save the installation time of the light guide plate, thereby facilitating the subsequent light guiding work of the light guide plate. At the same time, by setting the column, it can perform a position limiting operation on the reflective sheet, making the reflective sheet less likely to slide, thereby improving the reflective effect.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Reference Figure 1-3A light guide plate with a frosted surface structure includes a first light guide plate 1, a first column 3 is connected to the bottom end of the first light guide plate 1, and a slot 4 is opened on the inner side of the bottom end of the first column 3, a second light guide plate 2 is placed below the first light guide plate 1, and the top of the second light guide plate 2 is connected with a second column 5, and the top of the second column 5 is welded with a plug 6, and the plug 6 is plugged into the slot 4. The outer walls of the first light guide plate 1 and the second light guide plate 2 are both provided with a reserved groove 7, and the inner side depth of the reserved groove 7 is 1mm. By setting the reserved groove 7, it is convenient to place the light strip on Inside, the first light guide plate 1 and the second light guide plate 2 each include a light guide plate body 10, and a diffuser 8 is laid on the top of the light guide plate body 10. The surface of the diffuser 8 is frosted to facilitate light diffusion. A reflective sheet 9 is placed at the bottom of the light guide plate body 10, and light guide points 11 are printed on the bottom surface of the light guide plate body 10. The inner side of the reflective sheet 9 is provided with through holes that match the first columns 3, and the first columns 3 are distributed in two groups. By setting the columns, it is possible to perform a position-limiting operation on the reflective sheet 9, making it difficult for the reflective sheet 9 to slide, thereby improving the reflective effect.

[0020] The structure of the first light guide plate 1 is consistent with that of the second light guide plate 2, and the first light guide plate 1 forms a detachable structure with the second light guide plate 2 through the first column 3, the slot 4, the plug 6, the second column 5, and the second light guide plate 2. By plugging the plug 6 into the slot 4, the first light guide plate 1 and the second light guide plate 2 are spliced ​​together, and they are symmetrically distributed. Then, the installation work is performed between the mounting frame, which can effectively save the installation time of the light guide plate.

[0021] Working principle: When in use, the staff first inserts the plug 6 at the second column 5 into the slot 4 at the first column 3 to complete the splicing of the first light guide plate 1 and the second light guide plate 2, so that they are symmetrically distributed. Then, the light strip is placed in the reserved groove 7 of the light guide plate. Subsequently, the light guide plate group is installed between the mounting frame. Finally, the light strip is started, and the light passes through the light guide point 11. The reflected light will diffuse to all angles, and then the reflection condition is destroyed and emitted from the front of the light guide plate. Through the light guide point 11, the light guide plate can emit light evenly. Among them, the reflective sheet 9 can reflect the light exposed on the bottom surface back into the light guide plate, which is used to improve the efficiency of light use, so that under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low, thereby completing the light guiding work through the light guide plate.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
