Description

Technical Field

[0001] This utility model relates to the field of LED lighting, and in particular to an industrial and mining lamp. Background Technology

[0002] Industrial and mining lamps, as high-power, high-brightness lighting equipment, are widely used in large, high-ceilinged places such as factories, warehouses, and stadiums. With the popularization of LED technology, modern industrial and mining lamps have gradually replaced traditional light sources such as metal halide lamps due to their advantages such as high luminous efficiency, long lifespan, energy saving, and environmental protection.

[0003] Traditional LED industrial and mining lamps typically consist of a lamp holder, driver power supply, LED light source module, and heat dissipation structure. However, in practical applications, existing industrial and mining lamps still have some shortcomings that need improvement. First, the luminous efficiency and lifespan of LED chips are closely related to operating temperature. Poor heat dissipation performance will lead to accelerated light decay and a significantly shortened lifespan. Many existing products have relatively simple heat dissipation structure designs with limited heat dissipation area, or have not fully considered the optimization of heat dissipation paths, resulting in serious heat accumulation during long-term operation.

[0004] Secondly, industrial and mining environments are often dusty, humid, and may even contain corrosive gases. If the interface where the wire enters the lamp shade from the lamp holder is not properly sealed, moisture and dust can easily intrude, which can not only corrode the internal drive circuit and LED light board, but also cause safety hazards such as short circuits.

[0005] Furthermore, in order to achieve large-area uniform illumination, industrial and mining lamps usually need to be equipped with light guide plates and diffuser plates. However, if the optical design is not proper, obvious dark areas, bright spots, or glare can easily occur, affecting the lighting quality and visual comfort.

[0006] In addition, the stability and alignment of the connection between the lamp holder and the lampshade are also very important. An unreliable connection may cause the lamp to loosen during long-term use or when subjected to vibration, affecting structural safety. It may also cause misalignment between the lampshade and the lamp holder, affecting the overall aesthetics and the direction of light projection. Utility Model Content

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an industrial and mining lamp that significantly improves heat dissipation, sealing, optical performance, and structural stability.

[0008] An industrial and mining lamp according to a first aspect of the present invention is characterized in that it comprises: The lamp holder includes a cup-shaped base body, a drive circuit board installed inside the base body, a hanging ring on the top of the base body, a number of positioning holes evenly distributed on the outer edge of the base body, a cover plate installed on the opening of the base body, and a number of through holes for wires to pass through the cover plate. The lampshade includes a disc-shaped cover with several radial heat dissipation parts at the upper end of the cover. Several threaded holes that mate with the positioning holes are evenly distributed in the middle of the upper end of the cover. An LED light board is installed at the bottom of the cover. A light guide plate is installed on the LED light board. Wires on the drive circuit board extend into the interior of the cover through the through holes and are electrically connected to the LED light board.

[0009] According to an embodiment of this utility model, an industrial and mining lamp has at least the following beneficial effects: The overall structure is compact and reasonable, achieved by combining a "cup-shaped" base with a "disc-shaped" cover. The drive circuit board is centrally installed inside the lamp holder, integrating drive and lighting functions, facilitating production, installation, and maintenance. The top "hanging ring" structure simplifies the high-altitude installation process and improves installation convenience. By evenly distributing "positioning holes" on the outer edge of the base and corresponding "threaded holes" on the cover, quick, precise alignment and secure connection between the lamp holder and the lamp cover are achieved. This connection method effectively prevents the lamp cover from loosening or misaligning due to vibration during long-term use, ensuring the structural stability and safety of the lamp. The "cover plate" makes the interior of the lamp holder an independent, sealed space, protecting the drive circuit board. The "through holes" on the cover plate allow wires to be routed systematically and centrally from the drive section to the lighting section, not only keeping the internal wiring neat but also providing a basis for setting a sealing structure at the through holes, thus improving the overall protection level. The upper part of the lampshade features several radial heat dissipation sections, forming the main heat dissipation area of ​​the lamp. This radial structure significantly increases the contact area with air, creating an effective heat dissipation path. This allows the heat generated by the LED panel during operation to be conducted and dissipated into the air in a timely manner, significantly reducing the junction temperature of the LED chip, effectively suppressing light decay, and extending the overall lifespan of the lamp. By covering the LED panel with a light guide plate, the light-emitting characteristics of the LED point light source are altered. The light guide plate effectively scatters and guides the light emitted by the LED, ensuring uniform light distribution across the entire light-emitting surface. This eliminates uncomfortable glare and noticeable bright spots and dark areas, providing a comfortable, uniform, and high-quality lighting effect, making it particularly suitable for industrial and mining environments where high light uniformity is required.

[0010] According to some embodiments of the present invention, the heat dissipation part is made of aluminum, and each heat dissipation part has multiple fins on its surface.

[0011] According to some embodiments of this utility model, a rubber sealing ring is embedded in the through hole, and the wire passes through the rubber sealing ring to form a waterproof sealing structure.

[0012] According to some embodiments of the present invention, the light guide plate is a circular polycarbonate plate, and the side of the light guide plate near the LED light panel is provided with diffusion dots.

[0013] According to some embodiments of this utility model, the number of positioning holes and threaded holes are both four, and they are distributed in a square.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] Example 1 Reference Figure 1 According to a first aspect of the present invention, an industrial and mining lamp mainly includes a lamp holder 100 and a lamp cover 200.

[0022] The lamp holder 100 includes a cup-shaped base 101. The base 101 has an internal space for mounting a driver circuit board 102. A hanging ring 103 is fixedly mounted on the top of the base 101, which can be connected to an external hanging chain or rod for quick suspension of the lamp. Several positioning holes 104 are evenly distributed on the outer edge of the open end of the base 101. A cover plate 105 is screwed onto the open end of the base 101, sealing the interior of the base 101. The cover plate 105 has several through holes for the wires of the driver circuit board 102 to pass through.

[0023] The lampshade 200 includes a disc-shaped cover 201. Several radially distributed heat dissipation portions 202 are provided on the outer side of the upper end of the cover 201. These heat dissipation portions 202 extend outward from the center of the cover 201, increasing the contact area with air. Several threaded holes 203 are evenly distributed in the middle of the upper end of the cover 201, with the positions of the threaded holes 203 corresponding one-to-one with the positioning holes 104 on the lamp holder 100. The lamp holder 100 and the lampshade 200 can be securely connected by screws passing through the positioning holes 104 and screwed into the threaded holes 203. An LED light board 204 is mounted on the bottom of the cover 201, and a light guide plate 205 is mounted on the LED light board 204. Wires leading from the drive circuit board 102 pass through through holes in the cover plate 105, enter the interior of the lampshade 200, and are either soldered to the LED light board 204 or electrically connected via connectors.

[0024] The industrial lamp provided in this embodiment has the following advantages: the combination of the cup-shaped lamp holder 100 and the disc-shaped lampshade 200 results in a compact structure and high integration. The hanging ring 103 makes high-altitude installation more convenient. The cooperation between the positioning hole 104 and the threaded hole 203 achieves precise positioning and stable connection between the two parts, effectively preventing loosening. The cover plate 105 seals and protects the drive circuit board 102, and the through holes on it ensure standardized wiring and provide a basis for subsequent sealing measures. The radial heat dissipation part 202 constitutes an efficient passive heat dissipation system, which can quickly dissipate the heat generated by the LED lamp board 204, delay light decay, and extend lifespan. The light guide plate 205 converts the LED point light source into a uniform surface light source, eliminating glare and zebra stripes, and providing a comfortable lighting environment.

[0025] Example 2 Based on Embodiment 1, this embodiment further defines the heat dissipation part 202.

[0026] Reference Figure 1 The heat sink 202 is made of aluminum. It is understood that the heat sink 202 may also be made of other highly thermally conductive metals, such as copper or aluminum alloys. On the surface of each heat sink 202, multiple parallel fins 2021 are integrally formed or machined.

[0027] The beneficial effects of this embodiment are as follows: by using materials with good thermal conductivity such as aluminum, heat can be quickly conducted from the base to the end of the fins 2021. The arrangement of the fins 2021 greatly increases the heat dissipation surface area within a limited space, thereby significantly improving the heat exchange efficiency between the heat dissipation part 202 and the surrounding air. Experimental data shows that under an ambient temperature of 25°C, after the industrial and mining lamp of this embodiment operates at full load for 2 hours, the junction temperature of the LED chip can be controlled below 65°C, far below its safe operating limit of 85°C, effectively ensuring the long-term luminous efficacy stability and service life of the lamp.

[0028] Example 3 Based on Example 1, this example further defines the through hole.

[0029] A ring-shaped rubber sealing ring is embedded inside the through hole. The wire passes through the central hole of this rubber sealing ring. Due to the elasticity of the rubber material, the central hole tightly wraps around the outer surface of the wire under the pressure of the wire.

[0030] The beneficial effect of this embodiment is that the rubber sealing ring forms an effective elastic seal between the through hole and the wire. This structure can prevent external moisture and dust from entering the lamp holder 100 through the gaps in the through hole, protecting the internal drive circuit board 102 from corrosion. This structure is simple and reliable, enabling the lamp to easily achieve an IP54 or higher protection rating, and is suitable for dusty or humid industrial environments.

[0031] Example 4 Based on Embodiment 1, this embodiment further defines the light guide plate 205.

[0032] The light guide plate 205 is a circular polycarbonate plate. It should be understood that the light guide plate 205 can also be made of other high light transmittance materials, such as acrylic (PMMA). On the side of the light guide plate 205 near the LED light panel 204, a large number of tiny diffusion dots are set by laser engraving or printing process.

[0033] The beneficial effects of this embodiment are as follows: polycarbonate material has high light transmittance and good impact resistance. The diffusion dots set on the light-incident surface can efficiently scatter and guide the direct light emitted by the LED light panel 204, disrupting the total internal reflection path of the light and making it more uniformly emitted from the light-emitting surface of the light guide plate 205. After testing, the illuminance uniformity (minimum illuminance / average illuminance) of the light-emitting surface of the industrial and mining lamp using this structure can be improved to over 0.8, effectively eliminating central bright spots and edge dark areas, resulting in a comfortable visual experience.

[0034] Example 5 Based on Embodiment 1, this embodiment further defines the positioning connection structure.

[0035] Reference Figure 1 There are four positioning holes 104 and four threaded holes 203. These four holes are arranged in a square around the central axis of the lamp.

[0036] It should be noted that the number of positioning holes 104 and threaded holes 203 is not limited to four. For example, in some other embodiments not shown, the number may also be three, arranged in an equilateral triangle. Three connection points can also form a stable surface connection, and assembly is faster.

[0037] The beneficial effects of this embodiment are as follows: by using four connection points distributed in a square, the connection force between the lamp holder 100 and the lamp cover 200 is more evenly distributed, the structural rigidity is better, and it can effectively resist vibration or stress from different directions, prevent deformation or loosening at the connection, and ensure the long-term reliability of the lamp in harsh industrial environments.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
