AI Technical Summary
The transparent panels of existing luminous platform signs are easily contaminated with dirt or left finger marks, resulting in poor visual effect.
A light guide structure is designed, in which an opaque light shielding part is provided at the lower end of the transparent panel, and the light of the light emitting element is injected into the light guide plate, so that the illuminance on one side of the light guide plate is higher than that on the transparent panel, forming a significant illuminance difference, so that the imprint on the transparent panel is not obvious.
By increasing the illuminance on one side of the light guide plate, the imprints on the transparent panel are effectively hidden, and the visual effect of the luminous platform is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desktop display products, in particular to a desktop sign. Background Art
[0002] Desk signs, also known as table signs, refer to signboards standing on the desktop, which are used to display or prompt Party A's information. As the requirements for display effects continue to increase, desk signs with luminous effects have appeared on the market, such as the Chinese utility model patent: Publication number CN216927978U luminous desk signs. In practice, it is found that transparent panels are easily contaminated with dust or leave fingerprints after being touched by fingers, and the imprints are particularly obvious under the existing light-guiding structure. The reason is that after the transparent panel is illuminated by the light from the bottom light-emitting component, the illumination difference between the transparent panel and the light guide plate is small, which makes it easy for the human eye to observe the imprint on the transparent panel. This results in a poor visual effect of the desk signs. For this reason, it is necessary to improve the light-guiding structure of the existing luminous desk signs. Utility Model Content
[0003] In view of the above problems, the utility model provides a light-guiding structure for a luminous table sign which can improve the appearance of the table sign.
[0004] The technical solution used by the utility model to solve the above problems is: a light-guiding structure of a light-emitting table sign, comprising a base and a plate body, the base is provided with a slot, the bottom of the slot is provided with a light-emitting component, and the lower end of the plate body is plugged into the slot; the plate body comprises a frame body, a light-guiding plate and at least one transparent panel, the transparent panel is located on one side of the light-guiding plate, and the frame body is connected to the periphery of the light-guiding plate and the transparent panel; the lower end of the frame body is provided with an opening, the opening is directly opposite to the top of the light-emitting component, the lower ends of the light-guiding plate and the transparent panel are located in the opening, and the lower end of the transparent panel is provided with a light-proof shading portion.
[0005] The pages of the luminous table sign of the utility model are placed between the transparent panel and the light guide plate, and the light of the luminous element is projected into the light guide plate to make the entire plate body bright and uniform. The light shielding part at the lower end of the transparent panel prevents the transparent panel from directly receiving the irradiation of the luminous element. After adopting the above structure, the illumination on one side of the light guide plate is higher than the illumination on the side of the transparent panel. Compared with the prior art, the advantage is that when viewing the luminous table sign, the imprint on the transparent panel cannot be clearly shown, thereby improving the visual effect of the luminous table sign.
[0006] Preferably, the light shielding part includes a light shielding coating on the surface of the transparent panel. The light shielding coating is sprayed onto the transparent panel, which is easy to operate.
[0007] Preferably, the light-shielding coating is provided at the lower end of the side surface of the transparent panel and the lower end surface of the transparent panel.
[0008] Preferably, the light-emitting component includes a light strip extending along the length direction of the slot, and a light strip groove for installing the light strip is provided at the bottom of the slot. The light strip groove is located directly below the light guide plate, and the width of the upper end of the light strip groove is greater than the width of the lower end.
[0009] Preferably, the width of the upper end of the light strip groove is less than or equal to the thickness of the light guide plate; and the light-shielding coating is located at the lower end of a side of the transparent panel close to the light guide plate.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0021] Embodiment 1
[0022] like Figures 1 to 3As shown, a light-guiding structure of a light-emitting table sign includes a base 1 and a plate body 2. The base 1 is provided with a slot 10. The bottom of the slot 10 is provided with a light-emitting component 3. The light-emitting component 3 includes a light strip 31 extending along the length direction of the slot 10. The bottom of the slot 10 is provided with a light strip slot 101 for installing the light strip 3. The light strip slot 101 is located directly below the light guide plate 22. The width of the upper end of the light strip slot 101 is greater than the width of the lower end, and the cross-section is trapezoidal. The lower end of the plate body 2 is plugged into the slot 10. The plate body 2 includes a frame body 21, a light guide plate 22 and at least one transparent panel 23. The transparent panel 23 is located on one side of the light guide plate 22. The frame body 21 is connected to the periphery of the light guide plate 22 and the transparent panel 23. In this example, there are two transparent panels 23, which are located on both sides of the light guide plate 22, and the spread is placed between the transparent panel 23 and the light guide plate 22. The lower end of the frame 21 is provided with an opening 210, and the opening 210 is directly opposite to the top of the light emitting element 3. The lower ends of the light guide plate 22 and the transparent panel 23 are located in the opening 210, and the lower end of the transparent panel 23 is provided with a light-proof shielding portion 231. The frame 21 is in a square ring shape, and a card slot is provided on the inner wall. The edge of the light guide plate 22 and the edge of the transparent panel 23 are card-connected to the card slot. The opening 210 is provided on the frame at the lower end of the frame 21, and the light guide plate 22 and the transparent panel 23 are installed in the frame 21 through the opening.
[0023] The light shielding part 231 includes a light shielding coating 2311 on the surface of the transparent panel 23. The light shielding coating 2311 is processed on the transparent panel by spraying, which is easy to operate.
[0024] The light shielding coating 2311 is disposed on the lower end of the side surface of the transparent panel 23 and the lower end surface of the transparent panel 23 .
[0025] Embodiment 2
[0026] like Figure 4 As shown, the difference from the first embodiment is that the width of the upper end of the light strip groove 101 is less than or equal to the thickness of the light guide plate 22 .
[0027] The light shielding coating 2311 is located at the lower end of the transparent panel 23 close to the light guide plate 22 .
[0028] The distance between the transparent panel 23 and the light guide plate 22 is greater than 4 mm.
[0029] The height of the light shielding coating 2311 on the side of the transparent panel 23 close to the light guide plate 22 is greater than half the width of the slot 10 .
[0030] The pages of the luminous table sign of the utility model are placed between the transparent panel 23 and the light guide plate 22, and the light of the light strip 31 is irradiated into the light guide plate 22 to make the entire plate body bright and uniform. The light shielding part 231 at the lower end of the transparent panel 23 prevents the transparent panel 23 from directly receiving the illumination of the light strip 31, so that the illumination on the side of the light guide plate 22 is higher than the illumination on the side of the transparent panel 23, forming a significant illumination difference. When the luminous table sign is in the luminous state, when viewing the luminous table sign, the imprint on the transparent panel 23 cannot be clearly seen, thereby improving the visual effect of the luminous table sign.
