Description

Technical Field

[0001] This utility model relates to the field of neon tubes, and in particular to a neon tube structure with a single-layer light guide structure. Background Technology

[0002] With the development of technology, existing neon tubes are generally composed of LED lights to achieve their colorful effects. However, in actual use, it has been found that when the length of the light body is long, if the LED light cannot be centered, a shadow will appear on the outer lampshade (although this shadow can be ignored when the visual distance is long, it will be noticeably dark when you walk closer), affecting the user experience.

[0003] For example, Chinese patent 202421245794.3 uses a multi-layer nested structure to reduce the shadow area of ​​light. However, in actual use, its silicone sleeve is rectangular. Although it effectively improves the light guiding and scattering effect, the silicone sleeve has a diamond-shaped corner, so there is a certain visual deviation at this position, which affects the overall light coverage. Utility Model Content

[0004] The main purpose of this invention is to propose a neon tube structure with a single-layer light guide structure, which aims to improve the existing neon tube structure, reduce the connection structure of the light-emitting position of the neon tube, and thus reduce the shadow surface (i.e., dark surface).

[0005] To achieve the above objectives, this utility model proposes a neon tube structure with a single-layer light guide structure, comprising:

[0006] A light guide tube, wherein the inner wall of the light guide tube is provided with a first positioning cavity, the first positioning cavity being used to install LED light strips;

[0007] The lampshade has a second positioning cavity on its inner wall, and a first connector and a second connector at both ends. The light guide tube is disposed within the second positioning cavity.

[0008] The inner wall of the lampshade and the inner wall of the light guide tube form a light guide cavity;

[0009] The two ends of the light guide tube are secured between the first connector and the second connector.

[0010] In the actual design, the first and second connectors are used to position the light guide tube, thereby preventing its displacement and also serving a locking function.

[0011] In actual locking, the lampshade can be locked onto the ends of the first and second connectors.

[0012] Alternatively, a first limiting groove is provided between the outer wall of the first connector and the inner wall of the lampshade, and a second limiting groove is provided between the outer wall of the second connector and the outer wall of the lampshade, thereby locking both ends of the lampshade between the first limiting groove and the second limiting groove.
