Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial and mining lamp technology, specifically an industrial and mining lamp that facilitates heat dissipation. Background Technology
[0002] Industrial and mining lamps, especially high-power LED industrial and mining lamps, are widely used in large spaces such as factories and warehouses. LEDs generate a lot of heat when they are working. If the heat cannot be dissipated in time, it will cause the chip junction temperature to rise, resulting in problems such as reduced luminous efficiency and shortened lifespan. Most existing industrial and mining lamps use passive heat dissipation methods.
[0003] CN221504940U discloses a heat-dissipating industrial and mining lamp, "including a lampshade, a heat sink, a mounting shell, and a light source; the heat sink includes a heat dissipation plate, which is fixedly connected to the lampshade, the light source is fixedly installed below the heat dissipation plate, a wire guide is fixedly installed on the heat dissipation plate, and several radially arranged heat dissipation fins are fixedly installed on the heat dissipation plate." This utility model dissipates heat from the industrial and mining lamp through the heat dissipation fins without a corresponding cooling fan. However, this method has drawbacks: firstly, the heat dissipation efficiency is limited, especially in enclosed or high-temperature environments; secondly, in order to maximize the heat dissipation area, the fins are made large and dense, increasing the overall weight and cost of the lamp and causing inconvenience for installation and maintenance.
[0004] Based on this, a mining lamp with convenient heat dissipation is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Heat dissipation fins are arranged in a circular array around the center on the upper surface of the substrate. A base plate is fixedly connected to the upper end of the light box. The upper ends of the heat dissipation fins are disposed above the upper surface of the base plate. A fan is disposed in the middle of the light box. Connecting rods are disposed around the fan and are fixedly connected to the inside of the light box through the connecting rods.

[0013] In one alternative: the switch is electrically connected to the battery, fan, LED light source and controller respectively.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes an active cooling system comprised of an aluminum substrate, 6063 aluminum alloy heat sink fins, and an axial fan. Compared to existing purely passive cooling industrial and mining lamps, this system significantly improves heat dissipation efficiency, rapidly removing heat generated during LED light source operation, effectively reducing chip junction temperature, thus ensuring LED luminous efficacy stability and greatly extending its lifespan. Simultaneously, due to the forced convection effect of the fan, the size and density of the heat sink fins can be appropriately reduced while maintaining the same heat dissipation efficiency, thereby reducing the overall weight of the lamp, lowering material costs, and simplifying transportation and installation. The chimney effect heat dissipation method aligns with the natural law of rising hot air, improving heat dissipation efficiency and preventing dust accumulation on critical heat dissipation components. This effectively enhances the practicality and heat dissipation performance of this invention. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] In one embodiment, such as Figures 1-5 As shown, a mining lamp with easy heat dissipation includes a lamp box 1, a heat dissipation component is provided inside the lamp box 1, and a mining lamp component is provided at the lower end of the lamp box 1. The heat dissipation assembly includes a substrate, which is disposed at the lower end of the light box 1 and has a through hole 12 on its surface. Heat dissipation fins 11 are arranged in a ring array around the center on the upper surface of the substrate. A base plate 6 is fixedly connected to the upper end of the light box 1. The upper ends of the heat dissipation fins 11 are disposed above the upper surface of the base plate 6. A fan 9 is disposed in the middle of the light box 1. Connecting rods 10 are disposed around the fan 9 and are fixedly connected to the inner side of the light box 1 through the connecting rods 10. In this embodiment, the heat generated when the LED light source 5 is working is first conducted to the substrate on which it is mounted. The through holes 12 on the surface of the substrate increase the air circulation area. The heat on the substrate is quickly conducted to the annular array heat sink fins 11 made of 6063 aluminum alloy to increase the heat dissipation area. At the same time, the fan 9 located in the middle of the light box 1 is started and stably supported by the connecting rod 10, generating an upward airflow. The airflow drives the air flow inside the light box 1, forming a cooling wind from bottom to top, which blows directly over the surface of the heat sink fins 11, accelerating the diffusion of heat into the air. Finally, the hot air is discharged from the base plate 6, completing the active heat dissipation cycle.
[0023] In one embodiment, such as Figure 3 As shown, the substrate is an aluminum substrate. Aluminum has excellent thermal conductivity, which can quickly conduct the heat generated by the LED light source 5 from the light-emitting core area to the entire substrate surface, laying an efficient foundation for subsequent heat dissipation through the heat sink fins 11 and the fan 9, and avoiding local heat accumulation at the light source attachment point.
[0024] In one embodiment, such as Figure 3As shown, the heat dissipation fins 11 are made of 6063 aluminum alloy. The heat dissipation fins 11 are made of 6063 aluminum alloy. This material not only has good thermal conductivity and is easy to be made into the required fin shape through extrusion process, but also has high strength and corrosion resistance, which can ensure that the heat sink can work stably for a long time in industrial and mining environments and maintain efficient heat dissipation capacity for a long time.
[0025] In one embodiment, such as Figure 3 As shown, the surface of the base plate 6 is provided with several air outlets 8. The air outlets 8 on the surface of the base plate 6 are the outlets of the heat dissipation air duct. The hot air is accelerated by the fan 9 and carries away the heat from the heat dissipation fins 11. Finally, it is smoothly discharged to the outside of the lamp through these air outlets 8, forming a complete and unobstructed airflow path, avoiding the hot air from lingering in the lamp box 1, thereby maintaining a high heat dissipation efficiency.
[0026] In one embodiment, such as Figure 4 As shown, the mining lamp assembly includes a lampshade 2, which is fixedly connected to the lower surface of the lamp box 1. Several air inlets 7 are opened around the upper end of the lampshade 2. An LED light source 5 is installed inside the lampshade 2. The LED light source 5 is attached to the lower surface of the substrate and coated with thermal grease to ensure good heat conduction. A controller 13 is installed in the middle of the upper surface of the substrate. In the mining lamp assembly, the air inlets 7 at the upper end of the lampshade 2 are the inlets for cooling air. The LED light source 5 is tightly attached to the lower surface of the substrate and coated with thermal grease to ensure that heat can be conducted away with minimal thermal resistance. Air is drawn in from the air inlets 7 and flows through the lampshade 2 and the interior of the lamp box 1 to provide cooling for the LED light source 5 and the heat dissipation components.
[0027] In one embodiment, such as Figure 2 As shown, a drive box 3 is fixedly connected to the upper surface of the base plate 6. The drive box 3 fixedly connected to the upper surface of the base plate 6 centrally houses and protects the electrical drive components of the lamp, separating them from the heat source and light source below. This avoids the adverse effects of high temperature on the performance and lifespan of electronic components, and improves the reliability and safety of the entire lamp system.
[0028] In one embodiment, such as Figure 5 As shown, the drive box 3 contains a storage battery 15, and a switch 14 is located on one side of the upper end of the drive box 3. A handle 4 is fixedly connected to the middle of the upper surface of the drive box 3. The storage battery 15 inside the drive box 3 can provide emergency power when the main power supply fails. The emergency lighting mode is activated by the switch 14, and the handle 4 facilitates the carrying and installation of the lamp. The switch 14 is used to control the on / off state of the entire lamp and integrates the switching function between normal lighting and emergency lighting.
[0029] In one embodiment, such as Figure 5As shown, the switch 14 is electrically connected to the battery 15, fan 9, LED light source 5 and controller 13 respectively. The switch 14 serves as the main control node, and manages the charging and discharging of the battery 15, the start and stop of the fan 9, the on and off of the LED light source 5 and the operation of the controller 13 through circuit connection.
[0030] The above embodiment discloses an industrial and mining lamp that facilitates heat dissipation. When the lamp is turned on by switch 14, the LED light source 5 starts to emit light and generate heat. The heat is quickly conducted to the aluminum substrate through the contact surface coated with thermal grease. The substrate conducts the heat laterally to the heat dissipation fins 11 made of 6063 aluminum alloy distributed in a ring array on its surface to increase the heat dissipation area. At the same time, the fan 9 located in the middle of the lamp box 1 starts, generating an upward suction force, which drives the cooling air in the environment to enter the lamp through the air inlet 7 at the top of the lamp cover 2. This cooling airflow flows upward, passes through the through hole 12 on the surface of the substrate and washes the surface of the heat dissipation fins 11. Forced convection carries away the heat on the fins. The heated air continues to rise and is finally discharged from the outside of the lamp through the air outlet 8 on the top plate 6, forming an efficient active heat dissipation cycle.
[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
