Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example
[0025] See Figures 1 to 3 As shown, a novel intrinsically safe LED explosion-proof sign light includes a lamp body 1 and a power supply structure 2 disposed on the top surface of the lamp body. In this embodiment, the lamp body includes a rear panel 11, a face ring 12, a sign plate 13, and a strip light source plate 14. The rear panel is made of plastic or metal, while the face ring can be made of plastic or metal. During processing, a cavity 3 is provided on the front side of the rear panel, and the face ring is attached to the front side of the rear panel and fixed with screws. The sign plate is located in the cavity, and its front edge is clamped and limited by the face ring. The strip light source plate is located on the top wall of the cavity, and the light from the strip light source plate shines downward through the sign plate. A drive box 4 is integrally formed on the top edge of the rear panel, and the power supply structure is disposed in the drive box and connected to the strip light source plate. The strip light source plate is a conventional structure in the prior art, simply applied, while the sign plate is an acrylic or glass plate with markings and text.
[0026] In this embodiment, the drive box is provided with a drive cavity 5 with an opening on the front, and a round cover 6 is provided at the opening of the drive cavity. The side wall of the drive box is provided with an electrical wire channel 7 that communicates with the drive cavity. The size of the round cover matches the size of the drive cavity, and the size of the electrical wire channel can be processed and set as needed.
[0027] Explosion-proof means that an internal explosion is allowed, but the explosion can be prevented from spreading to the external environment through a drive box or other means, thus achieving the explosion-proof effect. Intrinsically safe means preventing the generation of sparks or thermal effects that could ignite the explosion from the energy source.
[0028] Furthermore, the power supply structure includes a drive circuit board 21, a power input line 22, and a sealing structure 23; wherein the drive circuit board is a conventional structure of the prior art, which is simply applied. During assembly, the drive circuit board is fixed in the drive cavity and connected to the strip light source board. The power input line is set in the wire channel through the sealing structure, and the end of the power input line is connected to the drive circuit board.
[0029] The sealing structure includes a sealing ring 231, a sealing gasket 232, and a wire clamping nut 233. During assembly, the power input wire passes through the wire clamping nut, and the sealing ring and sealing gasket are positioned between the wire clamping nut and the wire channel for sealing. Furthermore, a waterproof ring 8 is provided between the round cover and the drive cavity. To improve waterproof sealing, the top of the drive box is fixed with mounting screw holes 9. These screw holes are primarily for mounting in the corresponding positions, improving installation convenience and reliability.
[0030] This utility model has positive effects: The structure of this utility model is reasonable. The drive box is integrally formed on the top edge of the rear panel, and the power supply structure is set in the drive box. The drive box can withstand the explosion pressure without deformation or cracking, which can improve the explosion-proof performance of the entire structure. In addition, the drive circuit board and the strip light source board are set separately, which is conducive to improving the safety and reliability of wiring. Furthermore, it works with the sign plate to ensure the effectiveness of the sign and has strong applicability.
[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
