As shown in Figures 1 to 6, the shell includes a first bottom shell 31 with an open top and a circle of step structure at the opening, a partition fixed at the opening of the shell and used to fix the LED module 1, a shell ring 33 arranged on the step structure, and a transparent plate 34 placed on the LED module 1 and used to close the shell ring 33.

A structural adhesive layer 4 is provided between the transparent plate 34 and the outer shell ring 33 ; a sealing strip 5 is provided between the outer shell ring 33 and the first bottom shell 31 ; the control component 2 is placed in the first bottom shell 31 , and the joint 3 is a waterproof plug and is arranged on the first bottom shell 31 .

By adopting the above technology, the structure of the outer shell is improved, and it is set to a structure of a first bottom shell, a partition, an outer shell ring 33 and a transparent plate 34, and the outer shell is divided into two cavities, respectively fixing the LED module 1 and the control component 2, which is easy to install and fix. By setting the structural adhesive layer 4, the sealing strip 5, and the waterproof plug, the waterproof performance of the entire LED sign light box is effectively improved. That is, the above structure is not only easy to install but also has good waterproof performance.

The connector 3 includes a wire connector and a signal line connector.

In order to facilitate the installation of the connector 3 and reduce the installation volume, the first bottom shell 31 is provided with a recessed block 311, and the connector 3 is arranged in the recessed block.

In order to further improve the waterproof performance, the first bottom shell 31 and the outer shell ring 33 are fixedly connected by waterproof screws 6.

In order to further improve the waterproof performance, as shown in FIG. 2 , a step structure may be provided in the outer shell ring 33 , and the step structure is used to receive and fix the transparent plate 34 .

Specifically, in order to achieve further protection, a preset box can be arranged outside the housing. There are many ways to implement the preset box.

As an example, referring to Figures 3 to 6, the preset box includes a second bottom shell 71 with an open top and a top cover assembly 73 for closing the second bottom shell 71. In order to facilitate quick installation, a fixing ring 72 is provided on the top cover assembly, and a wire outlet hole and a spring 711 are provided on the second bottom shell 71. The wire outlet hole is used to lead out the wires and signal lines, wherein the wire outlet hole is not shown in the figure.

The outer shell ring 33 comprises a bottom plate ring 331 for fixedly connecting with the first bottom shell 31, a vertical plate 332 arranged perpendicularly to the bottom plate ring 331, and a top plate ring (333) arranged parallel to the bottom plate ring (331), wherein the top plate ring (333) and the bottom plate ring 331 are respectively arranged at two ends of the vertical plate 332. A fixing column (82) is arranged on the vertical plate (332) for cooperating with the top plate ring (333) to realize the clamping and fixing of the spring sheet (711).

A spring clip 81 for fixing to the fixing ring 72 is fixed on the bottom plate ring 331 .

Here, the bottom plate ring 331 and the top plate ring (333) are a circle of plate-like structures to enhance the waterproof performance. The spring sheet 711 is a deformable sheet-like structure. When installing, just press the spring sheet 711 to bend and deform it, and the clamping hole 712 can be clamped in the gap between the fixing column 82 and the top plate ring (333), which is very convenient to operate.

In order to facilitate the disassembly and assembly of the spring sheet 711, an operation hole (712) is provided on one end of the spring sheet (711) close to the free end. A hole structure (713) is provided on one end of the spring sheet (711) close to the fixed end. By providing the operation hole, disassembly and assembly can be achieved by assisting pushing with the help of an external tool, such as a screwdriver.

Since the spring piece (711) is a metal piece, it has a certain structural strength to improve its structural stability. In order to weaken the structural strength of its fixed end and facilitate deformation, a hole structure (713) is provided at one end of the fixed end, i.e., the deformation end, to weaken its structural strength and facilitate disassembly and assembly.

The spring clamp 81 includes a first spring leaf and a second spring leaf, one end of which is fixed to the bottom plate ring 331 and the other end is provided with an L-shaped clamping structure. As shown in FIG5 , the two L-shaped clamping structures are arranged facing each other, so that a fixed cavity 811 and a clamping opening 812 are formed between the first spring leaf and the second spring leaf. When fixing, by pressing the fixing ring, the fixing ring can be placed in the fixing cavity 811 from the clamping opening 812, which is convenient for installation.

Specifically, the transparent plate 34 can be made of 5+5 laminated tempered glass. The sealing strip 5 can be made of silicone strips, rubber strips, etc. The first bottom shell can be made of aluminum shell. The outer shell ring 33 can be made of galvanized sheet. The preset box adopts the structure shown in Figure 3 and is welded with galvanized steel sheet. The size of the preset box is set to 1200X300X90. When this specific structure is adopted, it meets the waterproof IP68 and can be installed on a wet ground. It can be widely used in the advertising industry and the high-speed rail information sign industry.
