Description

Technical Field

[0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp. Background Art

[0002] As people's quality of life continues to improve, the requirements for the efficiency, durability and environmental performance of lighting systems are becoming more and more stringent. In this context, high-power LED lamp beads stand out in many lighting applications with their excellent brightness, ultra-long life and significant energy-saving effects. However, while high-power LED lamp beads emit light efficiently, they also generate a lot of heat. If this heat is not discharged in a timely and effective manner, the operating temperature of the LED light-emitting element will rise sharply, which will not only reduce the luminous efficiency and color stability, but also accelerate material aging, and even cause serious physical damage such as package rupture, thereby greatly reducing the service life of LED lamps.

[0003] At present, many LED lighting fixtures used in industrial environments such as factories often have a relatively simple heat dissipation design, mainly relying on natural heat dissipation or a simple heat sink structure, which is difficult to effectively cope with the high heat generated by long-term high-load operation. These lamps frequently encounter overheating problems in actual applications, resulting in performance degradation, accelerated light decay, and even direct damage, which not only greatly increases the maintenance cost of the enterprise, but also seriously affects the normal production operations and the long-term stability of lighting quality.

[0042] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0043] The present invention provides a technical solution:

[0044] See also Figures 1 to 6 An LED lamp comprises an LED lamp bead board 1 and a lamp housing 2 fixedly mounted on the outer circumferential surface of the LED lamp bead board 1, a lampshade 3 fixedly mounted on the inner side of the lamp housing 2 is arranged at the bottom of the LED lamp bead board 1, and a heat dissipation mechanism 4 is arranged at the top of the LED lamp bead board 1.

[0045] The heat dissipation mechanism 4 includes a lamp bead plate heat dissipation component 41, an auxiliary accelerated heat dissipation component 42 and a lampshade heat dissipation component 43. Through the lamp bead plate heat dissipation component 41, the auxiliary accelerated heat dissipation component 42 and the lampshade heat dissipation component 43, these components work together on the LED lamp, effectively solving the problem of high heat generated by high-power LED lamp beads. The lamp bead plate heat dissipation component 41 is responsible for preliminary heat dissipation, the auxiliary accelerated heat dissipation component 42 accelerates the heat dissipation speed through forced convection, and the lampshade heat dissipation component 43 ensures that the lampshade temperature is moderate and maintains the lighting quality. The three work together to improve the heat dissipation efficiency and stability of the LED lamp.

[0046] The lamp bead board heat dissipation assembly 41 includes a graphene heat sink 411 fixedly installed on the top of the LED lamp bead board 1, a base ring 412 is fixedly installed at the center of the top of the graphene heat sink 411, and a plurality of heat sink fins 413 are fixedly installed on the outer circular surface of the base ring 412. The graphene heat sink 411 is used as a core component, and its thermal conductivity is good, which facilitates the transfer of heat to the plurality of heat sink fins 413, forming an efficient heat conduction and dispersion structure.

[0047] The auxiliary accelerated heat dissipation component 42 includes a fin heat dissipation air box 421 arranged on the inner side of the base ring 412 and fixedly connected to the top of the LED lamp bead board 1, and a plurality of fin heat dissipation tubes 422 connected to the inner cavity of the fin heat dissipation air box 421 and penetrating the base ring 412 are fixedly installed on the outer cylindrical surface of the fin heat dissipation air box 421, and an air guide main pipe 423 connected to the inner cavity of the fin heat dissipation air box 421 is fixedly installed at the top center of the fin heat dissipation air box 421. The heat generated by the LED lamp bead board 1 is quickly absorbed by the graphene heat sink 411 and conducted to the base ring 412 and the wavy heat dissipation fins 413 on its outer cylindrical surface, which significantly increases the heat dissipation area, accelerates the natural dissipation of heat, and effectively reduces the working temperature of the LED lamp bead board 1.

[0048] The auxiliary accelerated heat dissipation component 42 also includes a fin heat absorbing plate 424 fixedly installed on the top of the heat dissipation fin 413, a coolant placement coil 425 fixedly installed inside the fin heat absorbing plate 424, a blower fixing frame 426 fixedly installed on the top of the fin heat absorbing plate 424, a blower 427 fixedly installed on the inner side of the blower fixing frame 426, an air outlet end of the blower 427 is fixedly connected to an air inlet end of the air guide pipe 423, through the fin heat dissipation air box 421 and the fin heat dissipation pipe 422 on its outer cylindrical surface, combined with the air guide pipe 423, the wind generated by the blower 427 is guided to blow evenly through the heat dissipation fins 413, thereby accelerating the convection loss of heat and improving the heat dissipation efficiency.

[0049] The lampshade heat dissipation assembly 43 includes a lampshade heat dissipation air box 431 fixedly installed on the outside of the air guide pipe 423 and connected with the inner cavity of the air guide pipe 423, a plurality of lampshade heat dissipation bent pipes 432 connected with the inner cavity of the lampshade heat dissipation air box 431 are fixedly installed on the outer circular surface of the lampshade heat dissipation air box 431, a lampshade heat dissipation air ring 433 fixedly connected with the outer circular surface of the lamp housing 2 is fixedly installed on the air outlet end of the lampshade heat dissipation bent pipe 432, and a plurality of air outlets 434 connected with the inner cavity of the lampshade heat dissipation air ring 433 are opened on the inner circular surface of the lampshade heat dissipation air ring 433. Through the lampshade heat dissipation air box 431, the lampshade heat dissipation bent pipe 432, the lampshade heat dissipation air ring 433 and the air outlet 434, the processed wind is guided to the periphery of the lamp housing 2 and the lampshade 3, thereby effectively reducing the temperature of the lampshade, preventing overheating from affecting the lighting and service life, and reducing dust accumulation, thereby maintaining the cleanliness of the lamp and the lighting quality.

[0050] Furthermore, a plurality of heat sink fins 413 are in contact with the top of the graphene heat sink 411, wherein the heat sink fins 413 are wavy in shape. By virtue of the wavy heat sink fins 413 being in contact with the top of the graphene heat sink 411, the heat sink area is increased and the heat radiation effect is optimized, thereby accelerating the natural heat dissipation speed, more effectively reducing the operating temperature of the LED lamp bead board 1, and improving the heat dissipation efficiency.

[0051] Furthermore, the fin heat pipes 422 and the heat dissipation fins 413 are arranged in an interlaced manner and evenly distributed on the graphene heat sink 411 along a circular trajectory. By staggering the fin heat pipes 422 and the heat dissipation fins 413 and evenly distributing them along the circumference, it is ensured that wind energy blows evenly through the heat dissipation fins 413, thereby improving the heat dissipation efficiency, optimizing space utilization, and enhancing the overall heat dissipation performance.

[0052] Furthermore, the interior of the fin heat absorbing plate 424 is hollow, wherein the fin heat absorbing plate 424 is made of aluminum alloy. The fin heat absorbing plate 424 is hollow and made of aluminum alloy, and the high thermal conductivity of aluminum alloy is used to accelerate heat conduction. At the same time, the hollow design facilitates the installation of the coolant placement coil 425.

[0053] Furthermore, the coolant placement coil 425 is composed of a plurality of annular tubes and a plurality of straight tubes connected to the annular tubes, wherein the coolant placement coil 425 is filled with antifreeze. The heat exchange area is increased by the annular and straight tube structure of the coolant placement coil 425. The antifreeze filled inside has a high specific heat capacity, which effectively absorbs and disperses the heat of the cooling fins 413.

[0054] Furthermore, the blower fixing frame 426 is made of insulating material. By making the blower fixing frame 426 of insulating material, the heat generated by the blower 427 during operation is effectively isolated from being transferred to the fin heat absorption plate 424, thereby avoiding affecting the heat dissipation efficiency of the antifreeze in the coolant placement coil 425.

[0055] Furthermore, an insulating lamp holder 5 fixedly connected to the fin heat absorbing plate 424 is fixedly installed on the top of the blower 427, a hanger 6 is fixedly installed on the top of the insulating lamp holder 5, and a mounting plate 7 is fixedly installed on the top of the hanger 6. The insulating lamp holder 5, the hanger 6 and the mounting plate 7 installed on the top of the blower 427 form a stable hanging structure, which is convenient for rapid installation and positioning of LED lamps in industrial environments. At the same time, the insulating lamp holder 5 isolates heat transfer, protects the upper structure from heat loss, and ensures safe and stable operation of the lamp.

[0056] Furthermore, mounting nails are provided at the four corners of the mounting plate 7, which facilitate the LED lamp to be quickly and firmly installed at a designated location in an industrial environment such as a factory, thereby ensuring the stability and safety of the lamp during use.

[0057] When used specifically, the working principle of the present invention is as follows:

[0058] When installing the LED lamp, first use the mounting nails on the mounting plate 7 to fix it to a designated location in an industrial environment such as a factory. When the LED lamp is powered on, the blower 427 automatically starts and begins its auxiliary heat dissipation process. When the LED lamp is lit, the LED lamp bead board 1 generates a large amount of heat. This heat is first quickly absorbed and dispersed by the graphene heat sink 411 located on the top of the LED lamp bead board 1. The graphene heat sink 411, with its excellent thermal conductivity, can effectively conduct heat to the base ring 412 at its top, and further transfer it to a number of wavy heat sink fins 413.

[0059] The design of the heat sink fin 413 adopts a wavy shape. Compared with the traditional straight heat sink fin, this design not only significantly increases the heat dissipation area and optimizes the heat radiation effect, but also speeds up the natural dissipation of heat by increasing the surface area, thereby more effectively reducing the operating temperature of the LED lamp bead board 1.

[0060] At the same time, the auxiliary accelerated heat dissipation component 42 also starts to work together. The fin heat absorption plate 424 is fixedly installed on the top of the heat dissipation fin 413 to form an efficient heat absorption and conduction structure. The coolant placement coil 425 inside is filled with antifreeze. As a heat conduction medium, the antifreeze has a large specific heat capacity and can effectively absorb the heat on the heat dissipation fin 413.

[0061] At this time, the wind generated by the blower 427 is guided to two main directions through the air guide pipe 423: one is to enter the lampshade heat dissipation air box 431, and the other is to enter the fin heat dissipation air box 421. The wind entering the fin heat dissipation air box 421 will be further diverted to the inside of each fin heat dissipation tube 422. These fin heat dissipation tubes 422 and the heat dissipation fins 413 are arranged in an interlaced manner and evenly distributed on the graphene heat sink 411 along a circular trajectory, ensuring that the wind can blow evenly through each heat dissipation fin 413. After the wind is blown out from the fin heat dissipation tube 422, it blows directly to the gap between the fin heat absorption plate 424, greatly accelerating the circulation speed of the air around the fin heat absorption plate 424. This forced convection heat dissipation method further accelerates the heat dissipation speed of the heat dissipation fins 413 and improves the heat dissipation efficiency of the entire heat dissipation mechanism.

[0062] Finally, the wind processed by the fin heat dissipation air box 421 will further flow into the lampshade heat dissipation air box 431, and blow to the outer area of ​​the lamp housing 2 and the lampshade 3 through the lampshade heat dissipation bend pipe 432 and the air outlet 434 on the lampshade heat dissipation air ring 433. This design not only helps to reduce the temperature of the lampshade 3 and prevent the lampshade 3 from overheating and affecting the lighting effect and service life, but also has a certain dust removal effect, which can reduce the dust accumulated on the surface of the lampshade 3 and maintain the cleanliness and lighting quality of the lamp.

[0063] In summary, the LED lamp achieves efficient and rapid heat dissipation through the coordinated work of the graphene heat sink 411, the wavy heat dissipation fins 413, the auxiliary accelerated heat dissipation component 42 and the lampshade heat dissipation component 43, ensuring the stability and durability of the LED lamp under long-term high-load operation.

[0064] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
