Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing roller technology, specifically to a waterproof and dustproof LED mining lamp. Background Technology
[0002] In underground working environments such as mines and tunnels, miners' lamps are crucial lighting equipment for ensuring worker safety. With the development of LED technology, LED miners' lamps, due to their advantages such as high efficiency, energy saving, long lifespan, and high brightness, are gradually replacing traditional incandescent and fluorescent miners' lamps. However, the complex underground working environment, with its large amounts of dust and potential water exposure, places stringent requirements on the waterproof and dustproof performance of miners' lamps.
[0003] Existing LED mining lamps have several shortcomings in their waterproof and dustproof design. Some lamps only use simple sealing rings or outer shells, which are prone to aging and deformation over long-term use, leading to seal failure and ineffective prevention of dust and liquid intrusion. While some lamps have ventilation holes, these holes are not waterproofed or dustproofed, allowing dust and moisture to easily enter the lamp body, affecting the normal operation of LED chips and circuit components, and even causing safety hazards such as short circuits and leakage. Furthermore, the assembly structure of traditional mining lamps is relatively complex, making it easy for components to misalign during installation, resulting in poor sealing and increasing production and maintenance costs.
[0004] Therefore, developing an LED mining lamp that can achieve efficient heat dissipation, reliable waterproof and dustproof performance, and is easy to assemble and highly stable has become an urgent technical problem to be solved. Utility Model Content
[0005] The present invention aims to solve the problems mentioned in the background art by providing a waterproof and dustproof LED mining lamp.
[0006] The specific technical solution is as follows:
[0007] A waterproof and dustproof LED mining lamp includes a top cover, with LED beads mounted on the bottom of the top cover via a substrate, a hanging ring fixedly mounted on the top of the top cover, and a bottom shell mounted on the bottom of the top cover. A wire from the substrate passes through the top cover. An annular plate is integrally formed on the bottom of the top cover, and the bottom shell is fitted over the annular plate. A downward-sloping hole is formed on the bottom of the bottom shell, and a vertical central hole is formed at the top of the downward-sloping hole. An upward-sloping hole is formed on the annular plate, communicating with the top of the central hole. The downward-sloping hole, the central hole, and the upward-sloping hole form a heat dissipation and waterproof through-hole. A fiber dustproof mesh is inserted inside the heat dissipation and waterproof through-hole, and a transparent protective plate is installed on the bottom inside of the bottom shell.
[0008] As a preferred embodiment of this utility model, the bottom of the bottom shell is integrally formed with an annular bottom plate, and the transparent protective plate is installed between the annular plate and the annular bottom plate.

[0048] Example 1
[0049] like Figures 1-3This utility model provides a waterproof and dustproof LED mining lamp, including a top cover 100. LED beads 111 are mounted on the bottom of the top cover 100 via a substrate 110. A hanging ring 150 is fixedly mounted on the top of the top cover 100. A bottom shell 200 is mounted on the bottom of the top cover 100. Wires 112 of the substrate 110 pass through the top cover 100. An annular plate 120 is integrally formed on the bottom of the top cover 100. The bottom shell 200 is fitted onto the outside of the annular plate 120. The bottom shell 200 and the annular plate 120 are glued or bolted together. The bottom of the bottom shell 200 is open. A downward inclined hole 210 is provided, and a vertical central hole 211 is opened at the top of the downward inclined hole 210. An upward inclined hole 121 is opened on the annular plate 120, which communicates with the top of the central hole 211. The angle between the upward inclined hole 121 and the downward inclined hole 210 and the horizontal plane is between 20 and 60 degrees, and the diameter of the upward inclined hole 121 is larger than the diameter of the central hole 211. The downward inclined hole 210, the central hole 211 and the upward inclined hole 121 form a heat dissipation and waterproof through hole. The inside of the heat dissipation and waterproof through hole is filled with a fiber dustproof mesh 212. A transparent protective plate 300 is installed at the bottom of the bottom shell 200.
[0050] Overall structure and heat dissipation and waterproofing through holes:
[0051] The assembly structure of the top cover 100 and the bottom shell 200:
[0052] The nested design of the annular plate 120 and the bottom shell 200 forms a double-layer protective barrier, enhancing the impact resistance and sealing performance of the outer shell.
[0053] Lower inclined hole 210, middle hole 211 and upper inclined hole 121:
[0054] Heat dissipation effect: It forms a tortuous air convection channel to achieve heat dissipation, while preventing external liquids from entering directly.
[0055] Waterproofing effect: The angle between the downward inclined hole 210 and the horizontal plane is 20-60 degrees, and the liquid slides down the hole wall by gravity.
[0056] The diameter of the upward inclined hole 121 is larger than that of the middle hole 211, which creates a "throttling expansion" effect, reducing the airflow speed and reducing water droplet entrainment.
[0057] Dustproof effect: The 212-channel fiber dustproof mesh intercepts dust particles and ensures internal cleanliness.
[0058] The bottom of the bottom shell 200 is integrally formed with an annular bottom plate 310, and a transparent protective plate 300 is installed between the annular plate 120 and the annular bottom plate 310. The transparent protective plate 300 is clamped between the annular bottom plate 310 and the annular plate 120 to form a sandwich structure, which enhances the impact resistance of the protective plate and prevents water from entering at the edges.
[0059] The top and bottom peripheries of the transparent protective plate 300 are provided with annular sealing gaskets 320. The top sealing gasket prevents liquid from seeping in along the upper surface of the protective plate 300.
[0060] The bottom sealing gasket prevents liquid from entering through the gap between the base plate 310 and the protective plate 300, achieving IPX-level waterproofing (such as IP67 / IP68).
[0061] The bottom outer wall of the top cover 100 is integrally formed with an annular insert plate 130, and the top outer wall of the bottom shell 200 is provided with an annular groove 140 for the annular insert plate 130 to be engaged, forming a labyrinth-like sealing path, extending the liquid penetration path, and improving the waterproof level.
[0062] The top of the bottom shell 200 is integrally formed with a directional insert 220, which is preferably a triangular plate, to prevent incorrect installation. The bottom of the top cover 100 is provided with a directional slot 221 for the directional insert 220 to be inserted. The triangular plate-shaped directional insert 220 forces the correct assembly direction and avoids misalignment of the heat dissipation channel; it enhances the circumferential positioning accuracy between the top cover 100 and the bottom shell 200 and improves the torsional resistance.
[0063] At least twenty downward-sloping holes 210 are provided at equal angles. The at least twenty downward-sloping holes 210 distributed at equal angles form a symmetrical heat exchange surface, avoiding local overheating. The dense hole group disperses the impact force of water flow, and the adjacent inclined holes form a "water barrier interlocking" effect, reducing the risk of a single hole being breached.
[0064] The connection between the wire 112 and the top cover 100 is sealed with adhesive. The adhesive fills the microscopic gap between the wire 112 and the top cover 100, preventing liquid from penetrating along the surface of the wire.
[0065] Therefore, this waterproof and dustproof LED mining lamp:
[0066] 1. Waterproof and dustproof: Through the tortuous channel design of the lower inclined hole 210, the middle hole 211 and the upper inclined hole 121, combined with the fiber dustproof mesh 212, it achieves IP67 waterproof and dustproof rating (liquid / dust cannot penetrate).
[0067] High-efficiency heat dissipation: The air convection channel reduces the temperature of the LED beads and extends the life of the LED (for every 10°C reduction, the lifespan increases by 50%).

[0074] 4. Annular insert plate 130 and annular slot 140:
[0075] Mechanical locking: The interference fit provides radial restraint force (torsional strength > 5 N·m).
[0076] Waterproof labyrinth: Extends the liquid penetration path (passes IPX7 waterproof test: no penetration after immersion in 1m water for 30 minutes).
[0077] 5. Orientation plug 220 and orientation slot 221:
[0078] Misalignment prevention: The triangular plate design forces the correct assembly direction and avoids misalignment of the heat dissipation channel.
[0079] Torsional reinforcement: Shares the shear stress of the annular groove 140 (torsional strength increased by 30%).
[0080] 6. Uniform angular distribution of the downward inclined holes 210:
[0081] Uniform heat dissipation: 20 equally angled oblique holes form a symmetrical heat exchange surface with a temperature difference of <5℃.
[0082] Waterproofing optimization: Dense pores disperse the impact of water flow (no penetration was detected by a 60L / min spray test).

[0087] Assembly efficiency: Oriented structure 220 / 221 reduces assembly error rate to <0.1%.
[0088] Service life: Comprehensive protective measures extend the life of mining lamps to 2-3 times that of ordinary products.
