Description

Technical Field

[0001] This utility model relates to a fast heat dissipation LED light assembly, belonging to the field of LED light assemblies. Background Technology

[0002] LED light assemblies contain electronic components such as LED chips, circuit boards, and lenses. The lenses include LED chips, which inevitably generate heat during operation, making it difficult to dissipate heat from the surface of the LED chips.

[0003] The existing patent application, CN202322560176.X, entitled "An LED Light Source Module Circuit Board," discloses a design that incorporates thermal grease and heat sink fins. Thermal grease, a highly thermally conductive and insulating silicone material, possesses excellent electrical insulation and thermal conductivity, filling gaps between electronic components to improve heat dissipation. This heat is directed to the heat sink fins, which enhance heat dissipation efficiency, accelerate heat dissipation, and protect the device from overheating damage. A compressor and cooling pipes are incorporated, with the compressor cooling the refrigerant, which then flows through the cooling pipes into the gaps in the heat sink fins, quickly carrying away the heat. Furthermore, the design utilizes overlapping slots and overlapping protrusions. When multiple motherboards are needed, the overlapping protrusions can be inserted into the overlapping slots for quick assembly, improving work efficiency. Pipe joints, connecting hoses, and sealing rings are used to connect the cooling pipes of two motherboards, and the sealing rings prevent refrigerant leakage.

[0004] LED light groups are divided into flexible light strips and rigid light strips. LED light groups that require liquid cooling are mostly used in high-power LED spotlights on large stages. The liquid flowing in the pipes inside the light body will carry away a lot of heat from the LED beads, as in the aforementioned existing patents. However, there are still some drawbacks. First, most of the existing pipe arrangements use metal U-shaped cooling pipes, which are mostly circular with a small contact area. Second, large stages have higher requirements for lighting effects. Metal cooling pipes are close to the lights and can carry away a lot of heat, but they can also cause signal interference to the LED beads.

[0005] Therefore, this invention provides an LED light assembly that can dissipate heat quickly and prevent interference. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an LED light assembly that can dissipate heat quickly and prevent interference.

[0007] This utility model is implemented as follows:

[0008] A fast heat dissipation LED lamp assembly includes a circuit board, a lamp housing, and a liquid cooling system. The circuit board is detachably installed in the center of the lamp housing. The liquid cooling system is arranged around the circuit board and includes an inlet pipe for introducing coolant.

[0009] Several first multi-way valves, reducing pipes, and branch pipes are provided. One end of the first multi-way valve is connected to the inlet pipe, and the other outlets of the first multi-way valve are connected to reducing pipes. The reducing pipes are connected to the branch pipes arranged around the circuit board.

[0010] The second multi-way valve and the outlet pipe are connected to the ends of several branch pipes, and one end of the second multi-way valve is connected to the outlet pipe.

[0011] As a further improvement, both the first multi-way valve and the second multi-way valve are three-way valves.

[0012] As a further improvement, both the first multi-way valve and the second multi-way valve are two-way valves.

[0013] As a further improvement, it also includes a connector and an adapter, with the circuit board mounted on the connector and the adapter located below the connector and adapted to be connected to the connector.

[0014] As a further improvement, the converter head includes a hollow body.

[0015] Several liquid flow ports are provided, located on the outer surface of the main body, and connected to the branch pipe.

[0016] As a further improvement, the connector also includes several protrusions, the shape of which is similar to the heat dissipation vents on the connector, so that the adapter and the connector are cross-fitted.

[0017] As a further improvement, the liquid cooling system also includes a compressor and a heat exchanger arranged outside the lamp, and the inlet pipe and outlet pipe are connected to the compressor and heat exchanger via pipes.

[0018] As a further improvement, the outer surface of the reducing pipe and the branch pipe is provided with a metal shielding layer.

[0019] As a further improvement, the branch pipe is flat.

[0020] The beneficial effects of this utility model are:

[0021] ①The liquid cooling system of this utility model is arranged around the circuit board. It uses a compressor to exchange the coolant in the reducer and branch pipes, and then uses a heat exchanger to cool and remove the high temperature of the coolant.

Several LED beads are installed on the circuit board. The branch pipes are close to the LED beads and can quickly remove heat.

[0031] Example 1

[0032] Reference Figures 1-3 As shown, this embodiment provides a specific implementation of a fast heat dissipation LED lamp assembly, including a circuit board 10, a lamp housing 20, and a liquid cooling system 30. The circuit board 10 is detachably installed in the center of the lamp housing 20. The liquid cooling system 30 is arranged around the circuit board 10 and includes an inlet pipe 301 for introducing coolant.

[0033] Several first multi-way valves 302, reducers 303, and branch pipes 304 are provided. One end of the first multi-way valve 302 is connected to the inlet pipe 301. The other outlets of the first multi-way valve 302 are connected to reducers 303. The reducers 303 are connected to the branch pipes 304 arranged around the circuit board 10.

[0034] The second multi-way valve 305 and the outlet pipe 306 are connected. The second multi-way valve 305 is connected to the ends of several branch pipes 304, and one end of the second multi-way valve 305 is connected to the outlet pipe 306.

[0035] Furthermore, the liquid cooling system 30 also includes a compressor and a heat exchanger arranged outside the lamp, and the liquid inlet pipe 301 and the liquid outlet pipe 306 are connected to the compressor and the heat exchanger through pipes.

[0036] Furthermore, both the first multi-way valve 302 and the second multi-way valve 305 are three-way valves.

[0037] The liquid cooling system 30 of this utility model is arranged around the circuit board 10. It uses a compressor to exchange the coolant in the reducer 303 and branch pipe 304, and then uses a heat exchanger to cool and remove the high temperature of the coolant. Multiple branch pipes 304 are connected to the circuit board 10 by the first multi-way valve 302 and the second multi-way valve 305. The branch pipes 304 are filled with coolant. The circuit board 10 is equipped with several LED beads. The branch pipes 304 are close to the LED beads and can quickly remove heat.

[0038] Furthermore, the branch pipe 304 is flat. Compared with the cylindrical pipe, the flat branch pipe 304 has a larger contact area with the lamp housing 20, making it easier to carry away heat and thus achieving better heat dissipation.

[0039] In one specific embodiment, the outer surfaces of the reducer 303 and the branch pipe 304 are provided with a metal shielding layer 307, which is a conductive material layer used to prevent electromagnetic interference and radio frequency interference (RFI). Its working principle is based on electromagnetic induction and electrostatic shielding.

[0040] To reduce the interference of the metal shielding layer on the signal transmission of the LEDs on the circuit board 10, so as to achieve precise control of the LEDs.

[0041] Example 2

[0042] See Figure 4 The difference between this embodiment and embodiment 1 is that both the first multi-way valve 302 and the second multi-way valve 305 are two-way valves.

[0043] It also includes a connector 40 and an adapter 50. The circuit board 10 is mounted on the connector 40, and the adapter 50 is located below the connector 40 and is adapted to be connected to the connector 40.

[0044] Furthermore, the converter head 50 includes a hollow body 501;

[0045] A number of liquid flow ports 502 are provided. The liquid flow ports 502 are located on the outer surface of the main body 501 and are connected to the branch pipe 304 to allow coolant to flow.

[0046] Furthermore, the connector 40 also includes a plurality of protrusions 503, the shape of which is similar to the heat dissipation vents 401 on the connector 40, so that the adapter 50 and the connector 40 are cross-fitted.

[0047] The heat dissipation distribution in Example 1 is mainly for strip-shaped stage lights. However, for non-strip-shaped lights, such as the LED light assembly for which the patent application is titled "An Easy-to-Assemble LED Light Assembly", after the converter head 50 and the connector 40 are fixed together, the coolant flows through the connector 40 and quickly carries away the heat from the converter head 50, achieving rapid cooling.

[0048] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
