Description

Technical Field

[0001] This utility model belongs to the field of industrial and mining lamp technology, and specifically relates to an industrial and mining lamp that is easy to dissipate heat. Background Technology

[0002] Industrial and mining lamps, as important equipment in industrial lighting, are widely used in high-intensity working environments such as factories, warehouses, tunnels, and mines. Their main function is to provide high-brightness, long-term, and stable lighting. In actual use, industrial and mining lamps are usually kept on for extended periods, and the continuous operation of the internal light source and power supply generates a large amount of heat. Therefore, the heat dissipation performance of the lamps directly affects their lighting efficiency, service life, and safety.

[0003] Existing industrial and mining lamps generally use methods such as aluminum substrate heat conduction and metal shell natural heat dissipation to reduce internal temperature. However, due to the relatively closed structural design and limited air circulation path, heat is often difficult to dissipate in a timely and effective manner, leading to increased lamp body temperature, accelerated light decay of the light source, and even problems such as overheating and burnout of the power supply, which seriously affect the stability and service life of the product.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0017] like Figures 1 to 3 As shown, an industrial and mining lamp includes a lampshade 10, the lampshade 10 having a lampshade chamber 11 inside, a light source aluminum substrate 20 mounted on the surface of the lampshade chamber 11, and a lens 30 mounted on the outer side of the light source aluminum substrate 20 for focusing or diffusing light. The lampshade cavity 11 has a central protrusion 12 in the middle, the light source aluminum substrate 20 has a first central opening 21 in the middle, and the lens 30 has a second central opening 31 in the middle. The central protrusion 12 passes through the first central opening 21 and the second central opening 31 in sequence. To achieve effective heat dissipation, a plurality of ventilation holes 121 are evenly opened on the outer surface of the central protrusion 12. The ventilation holes 121 can form an air convection path, accelerate the discharge of heat from the cavity, and improve the heat dissipation efficiency. The upper end of the lampshade 10 is equipped with a power supply box 40 to provide power to the lamp. In actual use, the heat generated by the light source is conducted to the central protrusion 12 through the light source aluminum substrate 20 and exchanged with air through the ventilation holes 121. Combined with the structural matching between the power supply box 40 and the lampshade cavity 11, the overall heat dissipation effect can be further enhanced, ensuring that the lamp maintains a low temperature rise during long-term operation, thereby extending the service life of the lamp.

[0018] In practical implementation, the lampshade chamber 11 has a plurality of heat dissipation openings 111 evenly distributed along its edge to assist in the rapid dissipation of heat inside the lamp. The power supply box 40 has a plurality of heat dissipation openings 41 evenly distributed along its edge. These openings 41 and openings 111 are arranged correspondingly and aligned vertically to form a continuous airflow path. In actual use, the heat generated by the lamp can not only be discharged through the vent 121 on the central protrusion, but also through convection ventilation via the heat dissipation channel between the lampshade chamber 11 and the power supply box 40, thereby further improving the overall heat dissipation efficiency. This structural design, through the coordinated operation of the heat dissipation openings between the lampshade 10 and the power supply box 40, significantly enhances the heat dissipation performance of industrial and mining lamps under long-term operating conditions, avoiding light decay or power overheating caused by heat accumulation, and ensuring the safe and stable operation of the lamp.

[0019] In practical implementation, the surface of the lampshade chamber 11 is uniformly provided with a plurality of first connecting through holes 112, the surface of the light source aluminum substrate 20 is uniformly provided with a plurality of second connecting through holes 22, and the surface of the lens 30 is uniformly provided with a plurality of third connecting through holes 32. The plurality of first connecting through holes 112, the plurality of second connecting through holes 22, and the plurality of third connecting through holes 32 correspond one to one, and are connected and fixed by fasteners passing through the first connecting through holes 112, the second connecting through holes 22, and the third connecting through holes 32, thereby fixing the light source aluminum substrate 20 and the lens 30 respectively in the lampshade chamber 11. This structural design not only improves the firmness of the installation, but also makes the assembly between the light source aluminum substrate 20 and the lens 30 simpler and faster. At the same time, the multi-point positioning of the connecting through holes can effectively prevent the light source components from shifting or loosening during use, further ensuring the illumination stability and service life of the lamp.

[0020] In practical implementation, the surface of the lens 30 is uniformly recessed with a plurality of annular lens grooves 33, and the surface of the light source aluminum substrate 20 facing the lens 30 is uniformly provided with a plurality of light-emitting beads 23. The plurality of light-emitting beads 23 are correspondingly arranged with the plurality of lens grooves 33. When the lamp is in use, the light emitted by the light-emitting beads 23 is guided, focused or diffused by its corresponding lens groove 33, thereby achieving an ideal light distribution effect and improving the uniformity of light output and lighting efficiency.

[0021] In practical implementation, the lampshade cavity 11 is symmetrically provided with fixing recesses 13 on both sides, and fixing through holes 131 are opened on the surface of both fixing recesses 13. The power box 40 is symmetrically provided with fixing through posts 42 on both sides inside. The two fixing through holes 131 and the two fixing through posts 42 are correspondingly arranged, and fasteners are used to pass through the fixing through holes 131 and fix them to the fixing through posts 42, so that the power box 40 is fixedly installed on the mounting lampshade 10. The structure is simple and the installation is convenient and stable.

[0022] In practical implementation, the upper surface of the power supply box 40 is provided with a mounting bracket 50. The mounting bracket 50 has symmetrically arranged bracket through holes 51 on both sides. The two bracket through holes 51 correspond to the two fixing through posts 42, and are connected and fixed by fasteners passing through the bracket through holes 51 and fixing through posts 42, thus fixing the mounting bracket 50 to the power supply box 40. This structural design makes the mounting bracket 50 and the power supply box 40 form a whole, facilitating the suspension, screwing, or snap-fit ​​installation of the entire lamp in actual industrial and mining environments. Because the installation method is stable and reliable, and the connecting parts between the bracket and the power supply box are standard parts, the installation process is simple and efficient, reducing installation costs and improving construction efficiency. During use, the mounting bracket can withstand the overall weight of the lamp and the vibration and impact during operation, ensuring the lamp can work stably at high altitudes or other harsh environments for a long time, exhibiting good structural strength and safety.

[0023] In summary, the lampshade 10 has a lampshade chamber 11 inside, a light source aluminum substrate 20 is mounted on the surface of the lampshade chamber 11, a lens 30 is mounted on the outer side of the light source aluminum substrate 20, a central protrusion 12 is provided in the middle of the lampshade chamber 11, a first central opening 21 is opened in the middle of the light source aluminum substrate 20, a second central opening 31 is opened in the middle of the lens 30, the central protrusion 12 passes through the first central opening 21 and the second central opening 31 in sequence, and a plurality of ventilation holes 121 are evenly opened on the outer surface of the central protrusion 12. The air opening 121 can form an air convection path. The upper end of the lamp cover 10 is equipped with a power supply box 40. The edge of the lamp cover chamber 11 is evenly provided with a plurality of heat dissipation openings 111. The edge of the power supply box 40 is evenly provided with a plurality of heat dissipation openings 41. The plurality of heat dissipation openings 41 and the plurality of heat dissipation openings 111 are correspondingly arranged. The industrial and mining lamp of this utility model enhances the heat dissipation performance under long-term operation conditions, avoids the phenomenon of light decay of light source or overheating of power supply due to heat accumulation, ensures safe and stable operation of lamp, and provides convenient installation and safe and stable use.
