AI Technical Summary
Existing road signs do not reflect light at night, making them difficult for pedestrians to see.
A luminous road sign was designed, which uses a transparent protective plate and an internal LED structure. It utilizes a power generation mechanism composed of solar panels and battery panels to absorb solar energy and store electrical energy during the day, and to illuminate the sign at night.
When there is no light at night, the sign can emit its own light to ensure that pedestrians can see the information on the sign, and it can also dissipate heat through the channel, which improves the reliability of the sign.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of traffic device technology, and more specifically to a luminous road sign. Background Technology
[0002] Traffic signs are facilities that use graphic symbols and text to convey specific information, manage traffic, indicate driving directions, and ensure smooth traffic flow and driving safety. They are mainly applicable to highways, urban roads, and all special-purpose roads, and have the nature of laws, which vehicles and pedestrians must abide by.
[0003] For example, patent CN210955992U discloses an LED illuminated road sign, including a support rod with a cavity inside. A movable block is slidably connected within the cavity, and a screw is inserted into the movable block. Both ends of the screw pass through the movable block and are rotatably connected to opposite sidewalls within the cavity. The screw and the movable block are threaded together. A first gear is provided on the bottom sidewall of the cavity, and the first gear is fixedly sleeved on the screw. A through hole communicating with the cavity is provided on the outer sidewall of the support rod, and a rotating rod is inserted into the through hole. One end of the rotating rod is fixedly connected to a turntable, and the other end of the rotating rod passes through the through hole and is fixedly connected to a second gear meshing with the first gear. An opening communicating with the cavity is provided on the side of the support rod away from the through hole. This utility model simplifies the disassembly of the LED sign by adjusting and fixing the mechanism, facilitating future maintenance and repair.
[0004] In practice, road signs are exposed and can only reflect light when illuminated at night, making them invisible to pedestrians.
[0005] It is evident that the aforementioned problems with existing technologies urgently need to be addressed. Utility Model Content
[0006] In view of the above-mentioned problems in the existing technology, one objective of this utility model is to provide a luminous road sign to solve the problem that the sign cannot reflect light in the absence of light at night, making it impossible for pedestrians to see the sign.
[0007] To achieve the above objectives, this utility model provides a luminous road sign, including a sign assembly. A luminous component is sleeved on the outer wall of the sign assembly. The luminous component includes a protective plate sleeved on the outer wall of the sign assembly. The protective plate is transparent. Through slots arranged in a linear array are opened inside the protective plate. Carding plates are snapped onto opposite sides of the protective plate. LED beads arranged in a linear array are arranged inside the carding plates corresponding to the protective plate. A power generation mechanism is provided on the top of the sign assembly.
[0008] Preferably, the sign assembly includes a sign, the outer wall of which is provided with a fixing block, and a support rod is snapped into the fixing block for insertion into the ground.
[0009] Preferably, the power generation mechanism specifically includes a solar panel disposed on the top of the protective plate, and a battery panel is disposed inside the plate.
[0010] Preferably, the solar panel is electrically connected to the battery panel, and the battery panel is electrically connected to the lamp beads.
[0011] Beneficial effects:
[0012] Compared with the prior art, the luminous road sign provided by this utility model has the following beneficial effects:
[0013] 1. By keeping the protective plate transparent, and allowing LED beads on both sides to illuminate the protective plate, the entire protective plate can be made to glow, thereby illuminating the sign.
[0014] 2. Ventilation is possible through the various slots inside the protective plate, which helps to dissipate heat from the solar panels and battery panels. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1-3 As shown, a luminous road sign includes a sign assembly 1. A luminous component 2 is sleeved on the outer wall of the sign assembly 1. The luminous component 2 includes a protective plate 201 sleeved on the outer wall of the sign assembly 1. The protective plate 201 is transparent. Through slots 205 arranged in a linear array are opened inside the protective plate 201. Clip plates 203 are snapped onto opposite sides of the protective plate 201. LED beads 206 arranged in a linear array are arranged inside the clip plates 203 corresponding to the protective plate 201. A power generation mechanism is provided on the top of the sign assembly 1.
[0023] The main purpose of this luminous road sign is to keep the protective plate 201 transparent so that when the LED beads 206 on both sides illuminate the protective plate 201, the entire protective plate 201 can emit light, thereby illuminating the sign 101; and the various through slots 205 provided inside the protective plate 201 can provide ventilation and heat dissipation for the solar panel 202 and battery panel 204.
[0024] In the technical solution provided by this utility model, by Figure 1 , Figure 2 and Figure 3 It can be seen that the sign component 1 includes a sign 101, and a fixing block 103 is provided on the outer wall of the sign 101. A support rod 102 is snapped into the fixing block 103 to be inserted into the ground for support and fixation.
[0025] Furthermore, the power generation mechanism specifically includes a solar panel 202 installed on the top of the protective plate 201, which can absorb sunlight to generate electricity. The card plate 203 is equipped with a battery panel 204 to store the electricity generated by the solar panel 202 to supply the lamp beads 206.
[0026] Furthermore, the solar panel 202 is electrically connected to the battery panel 204, and the battery panel 204 is electrically connected to the lamp beads 206.
[0027] Working principle: First, solar energy is absorbed through solar panel 202, and then electrical energy is generated and stored in battery panel 204;
[0028] Then, electrical energy is transmitted to the LED bead 206, which drives the LED bead 206 to emit light, thereby illuminating the transparent protective plate 201 and lighting up the sign 101;
[0029] Furthermore, ventilation can be provided through the through groove 205 inside the protective plate 201 to dissipate heat from the solar panel 202 and the battery panel 204.
[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
