Description

Technical Field

[0001] This utility model specifically relates to the technical field of LED lamp heat sinks, and specifically to an LED lamp aluminum alloy heat sink. Background Technology

[0002] While LED lights are known for their energy efficiency, they also generate heat while emitting light. If this heat cannot be dissipated in time, it will cause the LED chip temperature to rise, thus affecting the luminous efficiency and lifespan of the LED. Therefore, heat sinks are crucial for extending the lifespan of LED lights and improving their luminous efficiency. An LED heat sink is a device specifically designed to reduce the operating temperature of LED lights, and aluminum alloy is one of the materials used to make LED heat sinks. Aluminum alloy heat sinks have advantages such as high thermal conductivity, low specific gravity, easy processing, and low price. At the same time, aluminum alloy also has good corrosion resistance, allowing it to be used for a long time in humid or corrosive environments.

[0003] Currently used LED lamp heat sinks increase heat dissipation efficiency by increasing the surface area of ​​the heat sink, but this mainly involves adjusting the outer shell of the LED lamp board. The power supply used in some high-power LED lamps usually generates a lot of heat. At the same time, because aluminum alloy has good thermal conductivity, the heat generated by the LED lamp board will also be transferred to the power supply shell made of the same material. Therefore, in high-temperature environments, it is easy to affect the overall stability of use. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum alloy heat sink for LED lamps, in order to solve the problem mentioned in the background art that the heat dissipated by the LED lamp board is easily transferred to the power supply casing through the heat sink itself during use, which can easily affect the overall stability of use in high-temperature environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aluminum alloy heat sink for LED lights includes a heat sink housing and a mounting plate. A frame is installed on the front side of the heat sink housing, and an LED light board is installed inside the heat sink housing. A thermal pad is provided between the LED light board and the inner wall of the heat sink housing.

[0007] As a further embodiment of this utility model: a side shell is installed at the rear top of the heat dissipation shell, and the side shell is connected to the interior of the internal heat dissipation shell; at the same time, a first heat dissipation plate is installed on the rear outer wall of the heat dissipation shell.

[0008] As a further embodiment of this utility model: a power supply housing is installed on the rear side of the mounting plate, and an adapter module is installed on the top front side of the mounting plate. At the same time, a second heat sink is installed on the front side of the mounting plate.

[0009] As a further embodiment of this utility model: a fan wheel is installed at the bottom of the side shell, and the fan wheel is located between the first heat dissipation plate and the second heat dissipation plate.

[0010] As a further embodiment of this utility model: the first heat sink is distributed in a matrix, and both ends of each first heat sink have an arc-shaped structure.

[0011] As a further embodiment of this utility model: the adapter module extends through the side shell into the interior of the heat dissipation shell, and the adapter module is electrically connected to the LED light board.

[0012] As a further embodiment of this utility model: the two ends of the mounting plate are rotatably connected to the top two ends of the base, and an adjusting nut is installed at the connection between the mounting plate and the base.

[0013] As a further embodiment of this utility model: the second heat sink is distributed in a matrix, and the spacing between any two adjacent second heat sinks is the same as the spacing between any two adjacent first heat sinks.

[0014] As a further embodiment of this utility model: the end of the wind turbine is rotatably connected to the first cover plate, and the first cover plate is installed at the lower front end of the mounting plate; a second cover plate is provided below the first cover plate, and the second cover plate is installed at the bottom front end of the mounting plate, and the second cover plate has a grid structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model includes a heat dissipation shell, a first heat dissipation plate, a second heat dissipation plate, and a fan. The heat dissipation shell and the mounting plate are connected separately and are assembled by four screws and studs. After assembly, the first heat dissipation plate and the second heat dissipation plate are distributed correspondingly to each other but do not directly contact each other, and there is a certain gap between the first heat dissipation plate and the second heat dissipation plate. At the same time, the mounting plate and the first heat dissipation plate do not contact each other. Due to the reduction of the contact area, the heat transfer efficiency between the heat dissipation shell and the mounting plate is effectively reduced, and the heat generated by the LED light board and the power supply in the power supply shell is prevented from affecting each other during use.

[0017] 2. This utility model is equipped with a fan wheel, which actively guides external air into the space between the first heat sink and the second heat sink. The airflow enters from the bottom of the fan wheel and is accelerated out from the side. When the airflow passes between the first heat sink and the second heat sink, it will accelerate and carry away the heat on the first heat sink and the second heat sink, thereby simultaneously providing active heat dissipation to the heat sink shell and the mounting plate, thus improving the heat dissipation efficiency.

[0018] 3. This utility model is equipped with a base and an adjusting nut. The device can be stably placed in a designated position by the base, and the illumination angle of the LED light panel can be adjusted by tightening or loosening the adjusting nut, which improves the ease of use.

A second heat dissipation plate 10 is installed on the front side of the mounting plate 7. A fan wheel 11 is installed at the bottom of the side shell 5, and the fan wheel 11 is located between the first heat dissipation plate 6 and the second heat dissipation plate 10.

[0030] More specifically, the heat dissipation shell 1, the mounting plate 7, and the power supply shell 8 are all made of aluminum alloy.

[0031] As a further explanation of this embodiment, the frame 2 is made of aluminum alloy, and the inside of the frame 2 is provided with transparent explosion-proof glass. The frame 2 and the heat dissipation shell 1 are connected and fixed by screws.

[0032] In this embodiment, the first heat sink 6 is distributed in a matrix, and both ends of each first heat sink 6 are arc-shaped.

[0033] More specifically, the heat generated by the LED light board 3 is transferred to the heat dissipation shell 1 through the thermal pad 4, and then to the first heat dissipation plate 6, which is also made of aluminum alloy.

[0034] As a further explanation of this embodiment, the arc-shaped structure can increase the length of the first heat sink 6, thereby increasing the effective heat dissipation area of ​​the first heat sink 6.

[0035] In this embodiment, the adapter module 9 extends through the side shell 5 into the interior of the heat dissipation shell 1, and the adapter module 9 is electrically connected to the LED light board 3.

[0036] More specifically, the power supply required for the LED light board 3 needs to be installed inside the power supply housing 8, and the power supply housing 8 transmits power to the LED light board 3 through the adapter module 9.

[0037] As a further explanation of this embodiment, the adapter module 9 and the LED light board 3 are connected by a plug, and the modular assembly method facilitates the replacement of the LED light board 3.

[0038] In this embodiment, the two ends of the mounting plate 7 are rotatably connected to the top two ends of the base 14, and an adjusting nut 15 is installed at the connection between the mounting plate 7 and the base 14.

[0039] More specifically, the base 14 makes it easy to place the entire device stably on the ground.

[0040] As a further explanation of this embodiment, the included angle between the mounting plate 7 and the base 14 can be adjusted by tightening and loosening the adjusting nut 15.

[0041] In this embodiment, the second heat sink 10 is arranged in a matrix, and the spacing between any two adjacent second heat sinks 10 is the same as the spacing between any two adjacent first heat sinks 6.

[0042] More specifically, the second heat sink 10 can increase the effective heat dissipation area of ​​the mounting plate 7.

[0043] As a further explanation of this embodiment, the heat generated by the power supply inside the power supply housing 8 is transferred to the power supply housing 8 and then to the mounting plate 7 and the second heat sink 10.

[0045] More specifically, since the wind turbine 11 is relatively long, the first cover plate 12 provides a limit to the end of the wind turbine 11 to prevent the wind turbine 11 from swinging when rotating.

[0046] As a further explanation of this embodiment, the second cover plate 13 of the grille structure can perform simple filtration at the inlet of the airflow into the impeller 11, preventing larger debris from entering the interior of the impeller 11.

[0047] The working principle of this utility model is as follows: When in use, first connect the external power supply and start the LED light board 3. During use, the heat generated by the LED light board 3 is transferred to the heat dissipation shell 1 through the heat conduction pad 4, and then to the first heat dissipation plate 6. At the same time, the heat generated inside the power supply shell 8 is transferred to the mounting plate 7 and then to the second heat dissipation plate 10. Start the fan wheel 11, which drives the external airflow through the second cover plate 13 and into the fan wheel 11. After that, it is accelerated and discharged through the side of the fan wheel 11. Then, the airflow continuously passes between the adjacent first heat dissipation plate 6 and second heat dissipation plate 10, and the heat on the first heat dissipation plate 6 and the second heat dissipation plate 10 is carried away by the accelerated airflow.
