[0002] In places with flammable and explosive dust and gases, such as mine shafts, hospitals, and chemical and pharmaceutical plants, it is often necessary to have explosion-proof lighting fixtures. A very important explosion-proof principle is to limit the temperature of the outer shell surface, component surface or electronic component surface that comes into contact with explosive gases or explosive dust, and to limit the temperature of the electrical contact surface below the minimum ignition temperature or ignition temperature.

[0003] Currently, existing explosion-proof lighting fixtures have an integrated heat dissipation structure, which results in excessively high maintenance costs during repair, replacement, and upgrades. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof LED lamp, which is connected to the lamp body by a first heat sink and a second heat sink through positioning bolts to form a modular component. When maintenance or replacement of heat sink components is required, the bolts can be quickly disassembled for operation, reducing maintenance costs and shortening downtime, and facilitating subsequent upgrades to higher performance heat sink modules.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model discloses an explosion-proof LED lamp, comprising: an explosion-proof LED lamp 1, wherein the outer surface of the explosion-proof LED lamp 1 is provided with a fitting groove 6, the fitting groove 6 provides an installation and positioning structure for a first heat sink 7, and restricts its lateral displacement by adapting its shape; the fitting groove 6 is fixedly connected to the first heat sink 7 by a first positioning bolt 8, the first positioning bolt 8 passes through the first heat sink 7 and is fastened to the bottom screw hole of the fitting groove 6, realizing a rigid connection between the heat sink and the lamp body; the interior of the first heat sink 7 is provided with a plurality of first heat dissipation contact grooves 9, the first heat dissipation contact grooves 9 increase the contact area with the lamp body, improve the heat conduction efficiency, and quickly transfer the heat generated by the LED to the heat sink; the outer surface of the first heat sink 7 is fixedly connected with heat dissipation fins 10, the heat dissipation fins 10 increase the heat dissipation surface area, accelerate air convection, and dissipate the heat generated by the LED. The heat from the heat sink 7 is dissipated into the environment. The second heat sink 11 is fixedly connected to the upper surface of the explosion-proof LED light 1 by the second positioning bolt 12. The second positioning bolt 12 fixes the second heat sink 11 to the top of the lamp body, forming a double-layer heat dissipation structure. Several second heat dissipation contact grooves 13 are opened on the inner surface of the second heat sink 11. The second heat dissipation contact grooves 13 contact the upper surface of the lamp body, conduct heat from the top, and form a three-dimensional heat dissipation path with the first heat sink. A wire harness tube 4 is fixedly connected to the upper surface of the first heat sink 7. The wire harness tube 4 provides a protective channel for the internal wires of the lamp. Its installation above the first heat sink 7 facilitates the planning of the wiring route. A mating sleeve 5 is rotatably connected to the outer surface of the wire harness tube 4. The mating sleeve 5 can rotate around the wire harness tube 4 to facilitate the adjustment of the wire harness connection angle, while providing mechanical protection and sealing assistance.

[0021] The heat dissipation fins 10 and the first heat dissipation contact groove 9 are staggered. The staggered layout makes the heat conduction path intersect with the air flow path, which enhances the heat dissipation efficiency and avoids heat accumulation. The first positioning bolts 8 are symmetrically arranged around the first heat dissipation block 7. The symmetrical distribution of the first positioning bolts 8 ensures that the first heat dissipation block 7 is evenly stressed and prevents installation deformation from affecting the heat dissipation contact. The second heat dissipation block 11 is located above the first heat dissipation block 7. The upper and lower heat dissipation blocks form a vertical heat dissipation channel, which enhances natural convection heat dissipation by utilizing the principle of hot air rising. The size of the first heat dissipation block 7 is adapted to the size of the fitting groove 6. The size adaptation ensures that the first heat dissipation block 7 and the fitting groove 6 fit tightly, reducing contact thermal resistance and improving heat conduction efficiency. The explosion-proof LED light 1 is fixedly connected to the connecting frame 2 by fixing bolts 3. The fixing bolts 3 pass through the connecting frame 2 and connect to the screw holes of the lamp body, providing an external installation interface for the lamp to be fixed to the support structure. The four fixing bolts 3 are symmetrically arranged on the lower surface of the connecting frame 2. The symmetrical distribution of the fixing bolts 3 makes the connecting frame 2 stressed and balanced, ensuring that the lamp is installed firmly and preventing it from falling off due to uneven stress.

[0022] Working principle: First, align the fitting groove 6 of the explosion-proof LED light 1 with the bottom contour of the first heat sink 7. Utilize the size adaptation characteristics to ensure a tight fit between the two. Use shape positioning to limit lateral displacement and initially fix the position of the heat sink. Use the first positioning bolt 8, passing through the pre-set holes in the heat sink, to tighten and secure it with the screw holes at the bottom of the fitting groove 6, achieving a rigid connection and ensuring uniform force distribution. This prevents installation deformation from affecting heat conduction efficiency. Fix the wire harness tube 4 to the pre-set interface on the upper surface of the first heat sink 7, providing a protective channel for the internal wires of the lamp and planning the wiring route. Then, fit the mating sleeve 5 onto the outer surface of the wire harness tube 4, adjusting it to the required angle by rotation. This assists in wire harness connection and provides mechanical protection and sealing. Place the second heat sink 11 on the upper surface of the explosion-proof LED light 1 and fix it with the second positioning bolt 12, constructing a double-layer heat dissipation structure. At this time, the second heat dissipation contact groove 13 on the inner surface of the second heat sink 11 fits against the top of the lamp body, conducting heat from the top and forming a heat exchange with the first heat sink. The three-dimensional heat dissipation path involves a first heat dissipation contact groove 9 inside the first heat dissipation block 7, which increases the contact area with the lamp body, quickly absorbing the heat generated by the LED and conducting it to the main body of the heat dissipation block. The external heat dissipation fins 10 are staggered with the internal contact grooves, using the cross path of air convection and heat conduction to enhance heat dissipation efficiency. At the same time, the upper second heat dissipation block 7 uses the principle of hot air rising to enhance natural convection in the vertical direction, forming an all-round heat dissipation network. The connecting frame 2 is aligned with the bottom mounting surface of the explosion-proof LED lamp 1, and four symmetrically distributed fixing bolts 3 are passed through the holes on the lower surface of the connecting frame and tightened with the screw holes of the lamp body, providing a stable external mounting interface for the lamp and ensuring that it is reliably fixed to the wall, bracket, or other supporting structure. The internal wires are connected to the external power supply through the installed wire harness tube 4. After the power is turned on, the luminous performance of the lamp is tested, and the temperature distribution of each heat dissipation component is monitored to ensure that the heat dissipation system and mechanical structure work together normally and meet the safety requirements for use in an explosion-proof environment.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
