[0027] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.
[0028] See also Figures 1 to 10 A structure of an explosion-proof lamp includes a main body 1, wherein the main body 1 includes a lamp body 2 and a substrate 3 connected to the lamp body 2. An isolating portion 21 is provided on the inner side of the lamp body 2 so that the lamp body 2 forms a first cavity 22 and a second cavity 23 that are isolated from each other. The first cavity 22 is used to install the substrate 3, the second cavity 22 is used to install the electronic control component, and the substrate 3 is used to install the light source. An isolating portion 21 is provided on the inner side of the lamp body 2, which divides the internal space of the lamp body 2 into two mutually isolated first cavities 22 and second cavities 23. The first cavity 22 is used to install the substrate 3, on which the light source is installed, and the second cavity 23 is used to install the electronic control component. By arranging the light source and the electronic control component in different cavities, the heat generated by the light source will not directly affect the electronic control component, reducing the risk of damage to the electronic control component due to overheating, solving the problem that the heat generated by the light source causes the internal temperature of the explosion-proof lamp to be too high, thereby causing damage to the electronic control component, and effectively improving the safety and reliability of the explosion-proof lamp.
[0029] Furthermore, a first connecting portion 211 for fixing the substrate 3 is provided on the side of the isolation portion 21, and both the isolation portion 21 and the substrate 3 are provided with a connecting hole 212 through which the power line passes. The first connecting portion 211 is designed to fix the substrate 3, which can ensure that the substrate 3 is firmly installed inside the lamp body 2 and is tightly combined with the isolation portion 21 to avoid displacement or falling off of the substrate 3 due to vibration or other factors, effectively enhancing the stability of the explosion-proof lamp structure. Furthermore, the connecting hole 212 can allow the power line or other necessary wires to pass from the second cavity 23 through the isolation portion 21 to the first cavity 22, thereby realizing electrical connection between the light source and the electronic control component, which not only ensures the mutual isolation between the light source and the electronic control component, but also ensures the effectiveness and safety of the electrical connection.
[0030] Furthermore, the first cavity 21 includes a third cavity 28 provided between the side surface of the isolation portion 21 and the side surface of the lamp body 2, and a connection hole 212 through which the power line passes is provided on the upper side of the isolation portion 21. The third cavity 28 is located between the side surface of the isolation portion 21 and the side surface of the lamp body 2, which means that the design of the third cavity 28 increases the contact area between the first cavity 21 and the side wall of the lamp body 2, so that the heat in the first cavity 21 can diffuse to the outside of the lamp body 2 more quickly through the side wall of the lamp body 2, effectively enhancing the heat dissipation capacity of the explosion-proof lamp. Furthermore, the connection hole 212 is provided on the upper side of the isolation portion 21, which can shorten the length of the wires connecting the light source and the electronic control component as much as possible, avoiding the risk of the wires being squeezed or worn, thereby reducing the risk of circuit failure and effectively improving the reliability and structural stability of the explosion-proof lamp.
[0031] Furthermore, the main body 1 also includes a lampshade fastener 4 connected to the lamp body 2, and the lampshade fastener 4 is used to fix the relative position of the lamp body 2 and the lampshade. The lampshade fastener 4 is provided with a second connecting portion 41, and the lamp body 2 is provided with a fourth connecting portion 27 connected to the second connecting portion 41. The lampshade in the explosion-proof lamp plays the role of isolating the first cavity 22 from the outside. Some usage environments of explosion-proof lamps may contain gas or other flammable gases, and the design of the lampshade fastener 4 can ensure that the lampshade will not be displaced due to external impact or vibration during use, so that the lampshade can effectively isolate the outside from the inside of the explosion-proof lamp, effectively improving the structural stability and safety of the explosion-proof lamp. Furthermore, the second connecting part 41 located on the lampshade fastener 4 cooperates with the fourth connecting part 27 located on the lamp body 2 to achieve the purpose of fixing the lampshade fastener 4 and the lamp body 2. Specifically, the connection design between the second connecting part 41 and the fourth connecting part 27 can be a threaded fit, a snap fit or other type of connection mechanism. The use of this design also makes the installation and disassembly of the explosion-proof lamp more convenient. In summary, the design of adding the lampshade fastener 4 and fixing the lampshade through the cooperation between the second connecting part 41 and the fourth connecting part 27 not only improves the safety performance of the explosion-proof lamp, but also enhances its practicality and maintenance convenience.
[0032] Further, the isolation part 21 extends towards the side of the lamp cover fastener 4, and the cross-sectional shape of the isolation part 21 is in the shape of a reversed "U". The isolation part 21 extending towards the side of the lamp cover fastener 4 means that the distance between the light source and the lamp cover fastener 4 is shortened, and the heat generated by the light source can be transmitted to the outside more quickly through the lamp cover, effectively improving the heat dissipation capacity of the explosion-proof lamp. Further, the cross-sectional shape of the isolation part 21 presents the shape of a reversed "U", which means that the cross-section of the isolation part 21 is similar to a square frame with an opening facing one side, and the side where the opening faces is the second cavity 23. Such a design not only helps to improve the structural strength of the isolation part 21, but also forms an effective isolation space inside it to ensure the mutual isolation between the first cavity 22 and the second cavity 23.
[0033] Further, the main body 1 further includes a lamp base 5 connected to the lamp body 2. The lamp body 2 is provided with a third connecting part 25, and the lamp base 5 is provided with a third connecting hole 51 corresponding to the third connecting part 25. A fastener passes through the third connecting hole 51 and is connected to the third connecting part 25 to fix the lamp base 5 and the lamp body 2. The connection between the lamp base 5 and the lamp body 2 isolates the second cavity 23 from the outside, ensuring that the flammable gas outside cannot come into contact with the electric control components located in the second cavity 23, effectively improving the safety of the explosion-proof lamp. Further, the fastener passes through the third connecting hole 51 and is connected to the third connecting part 25, thereby realizing the fixation of the lamp base 5 and the lamp body 2. The fastener can be common fixing tools such as screws and bolts. Such a design can realize the disassembly of the lamp base 5 for the maintenance of the electric control components, effectively improving the maintenance convenience of the explosion-proof lamp. At the same time, it can ensure the connection stability between the lamp body 2 and the lamp base 5, effectively preventing the connection between the lamp body 2 and the lamp base 5 from loosening due to external vibration or impact, and then causing flammable gas or other liquids to enter the explosion-proof lamp internally and generate safety accidents, effectively improving the safety and reliability of the explosion-proof lamp.
[0034] Furthermore, the side of the lamp body 2 is provided with a plurality of heat dissipation portions 24 extending from the lampshade fastener 4 toward the lamp holder 5, and the heat dissipation portions 24 are in the shape of an elongated strip. The heat dissipation portions 24 are provided on the side of the lamp body 2 and extend from the lampshade fastener 4 toward the lamp holder 5. This means that the heat dissipation portions 24 are distributed along the length of the explosion-proof lamp, extending from the front side of the explosion-proof lamp where the lampshade fastener 4 is located to the rear side where the lamp holder 5 is located. This design allows the heat dissipation portions 24 to cover a larger surface area, increasing the opportunity for contact with the outside air, thereby improving heat dissipation efficiency. Furthermore, the elongated shape of the heat dissipation portions 24 can increase the heat dissipation area, which not only helps to evenly distribute heat, but also accelerates heat dissipation through natural convection of air while maintaining a compact structure. Specifically, the elongated heat dissipation portions 24 can be recessed toward the inside of the lamp body 2 or convex toward the outside of the lamp body 2. Both designs can increase the surface area of the lamp body 2 to achieve the effect of improving heat dissipation efficiency.
[0035] Furthermore, the lamp body 2 is provided with a protrusion 26, and the lamp holder 5 is provided with a groove 52 that matches the protrusion 26. The protrusion 26 cooperates with the groove 52 to achieve a stable connection between the lamp holder 5 and the lamp body 2. The protrusion 26 can be designed into different shapes, such as rectangular, semicircular, or other shapes. Through the cooperation of the protrusion 26 and the groove 52, the lamp body 2 and the lamp holder 5 can be quickly installed and removed, simplifying the maintenance and replacement process of the explosion-proof lamp. At the same time, the tight connection between the protrusion 26 and the groove 52 can effectively improve the sealing performance of the explosion-proof lamp, preventing external factors such as moisture, dust, and flammable gases from entering the interior of the explosion-proof lamp and affecting its normal operation, thereby effectively improving the safety and reliability of the explosion-proof lamp.
[0036] Furthermore, the wall thickness b of the lamp body 2 is smaller than the wall thickness a of the isolation portion 21. Since the lamp body 2 and the isolation portion 21 are made of the same material, under this condition, when the thickness of the heat-conducting material increases, the time required for heat to pass through the heat-conducting material will also increase. Therefore, when the wall thickness b of the lamp body 2 is smaller than the wall thickness a of the isolation portion 21, the time required for the heat in the first cavity 22 to propagate to the outside through the lamp body 2 is smaller than the time required for the heat to propagate to the second cavity 23 through the isolation portion 21, which means that the heat generated by the light source can propagate to the outside of the explosion-proof lamp faster, and the heat generated by the light source propagates to the second cavity 23 more slowly. Such a design can effectively improve the heat dissipation efficiency of the explosion-proof lamp, while reducing the speed at which heat propagates to the second cavity 23, thereby avoiding short circuit of the electronic control components due to excessive temperature in the second cavity 23, and effectively improving the service life and safety of the explosion-proof lamp.
[0037] Furthermore, the main body 1 is made of a high thermal conductivity material. The high thermal conductivity material can conduct heat quickly and effectively. Commonly used ones include stainless steel, aluminum alloy, and cast iron. These materials all have good thermal conductivity and also have other advantages. Stainless steel has good corrosion resistance and mechanical strength and is suitable for use in environments with strong chemical corrosion. Aluminum alloy has the advantages of being lightweight, high in strength, and easy to process. Cast iron is relatively inexpensive and at the same time is sturdy and durable. Therefore, they can all meet the usage requirements of explosion-proof lights. Using a high thermal conductivity material for the main body 1 can quickly transfer the heat generated by the light source to the outside through the main body 1, effectively improving the heat dissipation efficiency of the explosion-proof light.

Specifically, the second connection part 41 has a screw hole, and a fastener passes through the second connection part 41 and is connected to the fourth connection part 27 to achieve the fixed connection between the lamp cover fastener 4 and the lamp body 2.
[0043] Furthermore, the isolation part 21 extends towards the side of the lamp cover fastener 4, and the cross-sectional shape of the isolation part 21 is in the shape of a "冂".
