[0027] 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.

[0028] Example

[0029] In this embodiment, the front side refers to the surface illuminated by light, and the back side refers to the surface in contact with the mounting surface, such as a wall. This is only for the convenience of explanation and is not intended to limit the scope of the application.

[0030] See Figures 1 to 3 As shown, an LED dual-head explosion-proof emergency light includes a lamp body 1. A driving cavity 2 is located on the lower front of the lamp body, and two light source cavities 3 are located on the upper front of the lamp body. A through hole is provided between the two light source cavities and the driving cavity. In this embodiment, the through hole is mainly used to connect wires, facilitating the connection between the driving power supply and the light source structure. The driving cavity and the light source cavity are separated, allowing the corresponding cavity walls to withstand the pressure of an explosion during use, thus improving explosion-proof performance. Furthermore, the separate cavity can protect an individual structure, enhancing the inherent safety of the structure. The lamp body is a single, integrated structure, making it less prone to damage. Due to the high safety performance of the integrated structure, it can be used in environments such as petroleum, chemical, and pharmaceutical processing, as well as in coal mines or deep wells. It can also be used in hazardous environments such as those with explosive gases and dust. In practical applications, a built-in battery can be installed in the driving cavity for power supply.

[0031] In this embodiment, the side of the lamp body is provided with a wire through hole 4 that communicates with the light source cavity; the wire through hole is used to connect to an external backup power supply; the top surface of the lamp body is provided with a mounting screw hole 15 for mounting in the corresponding position.

[0032] Furthermore, a driving power supply 5 is fixed inside the driving cavity, an input wire 6 connected to the driving power supply is provided inside the wire through hole, a sealing structure 7 is provided between the input wire and the wire through hole, and a protective cover 8 is threadedly connected to the opening of the driving cavity; in this embodiment, the driving power supply is a conventional structure of the prior art, and is simply applied, so it is not described in detail. The lamp body is a cast aluminum lamp body, and the protective cover is an insulating plastic or aluminum cover. In practical applications, its drive chamber and power supply chamber are designed to be robust, capable of withstanding the explosion pressure generated when the internal battery or circuit fails, such as a short circuit or overcharge, leading to an explosion. This prevents heat or flame from escaping into the external hazardous environment, thus improving explosion-proof performance. Furthermore, the contact surface between the protective cover and the lamp body has strict long gap requirements, ensuring that even if an internal explosion occurs, the flame can be sufficiently cooled and extinguished as it passes through the long gap. Moreover, since the drive chamber and power supply chamber are set up separately, the circuits inside the internal chamber can be intrinsically protected independently. Even if a circuit failure occurs (short circuit, open circuit), the energy of the generated electric spark or thermal effect will be strictly limited and controlled to a very low level, insufficient to ignite the surrounding specific explosive environment. It also ensures that even if the wires in the explosion-proof chamber short-circuit to the light source chamber, the energy entering the light source chamber is still safe, achieving the purpose of intrinsic safety protection, thereby realizing dual explosion-proof protection.

[0033] Simultaneously, a light source structure 9 is fixed inside the light source cavity. This light source structure is connected to the driving power supply via wires, and an adjustable inner circular lampshade 10 is provided at the opening of the light source cavity. The wires of the light source structure are directed outwards through the inner circular lampshade. The inner circular lampshade primarily guides the light, improving the illumination effect. It can be a translucent plastic structure or a glass structure. In practical applications, corresponding indicator lights can also be installed for indication.

[0034] In this embodiment, an inner circular lampshade is used, which can be flexibly rotated or tilted, and no friction sparks will occur during the adjustment process. The inner circular lampshade is made of anti-static material.

[0035] In this embodiment, the light source structure includes an inner mounting ring 91, a lamp holder 92, a light source board 93, a reflector 94, and a glass panel 95. During assembly, the inner mounting ring is fixed to the light source cavity by screws, the lamp holder is fixed in the inner mounting ring, and the light source board is fixed to the front of the lamp holder. The reflector is disposed in the inner mounting ring, and the glass panel is located between the reflector and the inner circular lamp cover.

[0036] To improve sealing performance, a waterproof gasket 11 is provided at the connection between the mounting inner ring and the inner circular lamp cover; a limiting rubber ring 12 is fixed between the edge of the inner circular lamp cover and the inner wall of the light source cavity. The waterproof gasket between the mounting inner ring and the inner circular lamp cover can provide waterproof protection for the internal light source board and lamp bead holder, improving the stability of use. The limiting rubber ring is mainly used to limit the movement of the inner circular lamp cover, and at the same time, it ensures the stability and reliability of the rotation angle of the inner circular lamp cover when it rotates.

[0037] In this embodiment, a sealing and waterproof ring 13 is provided between the edge of the protective cover and the inner wall of the drive cavity. This can improve the sealing and waterproof performance of the drive cavity.

[0038] In this embodiment, the sealing structure includes a sealing ring 71, a gasket 72, and a hollow wire clamping nut 73. During installation and use, the input wire passes through the hollow wire clamping nut and the sealing ring. The sealing ring and gasket are located within the wire through-hole and are positioned by the threaded pressure of the hollow wire clamping nut. This improves the sealing and waterproofing performance between the input wire and the wire through-hole.

[0039] In this embodiment, during processing, the light source cavity is designed to be open at both the front and back; the edges of the mounting inner ring and the inner circular lampshade are fixed with screws; and a rear cover 14 is fixed to the back of the lamp body with screws, which seals the back of the light source cavity. This improves the ease of installation of the light source structure. In practical applications, the light source cavity can also be designed with a non-penetrating back, in which case the rear cover is not required.

[0040] This invention has several advantages: The structure is rationally designed, with a driving cavity and a light source cavity on the lamp body. The driving cavity houses the driving power supply, while the light source cavity houses the light source structure. The driving cavity and light source cavity withstand the pressure generated by the explosion of their respective structures, thus improving explosion-proof performance. Furthermore, their separate design allows for intrinsically safe protection of the internal structure, achieving dual explosion-proof protection, enhancing operational stability and reliability. It also facilitates the separate assembly, inspection, and maintenance of the driving power supply or the light source structure, making it more convenient and versatile.

[0041] 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.

[0042] 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.
