Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0015] see figure 1 As shown, a finned LED lamp radiator includes an LED light-emitting board 1, a fixed substrate 2, heat dissipation fins 3, and a heat pipe 4. One side of the fixed substrate 2 is provided with an LED light-emitting board 1, and the fixed The other side of the base plate 2 is provided with heat dissipation fins 3 , and several heat dissipation fins 3 are arranged regularly to form a dense heat dissipation fin group. The connection wire 5 of the LED luminescent board 1 is connected to the LED luminous board 1 through the heat dissipation fin 3 and the fixed substrate 2 for the LED luminous board to work. The material of the fix...

Abstract

The invention discloses a fin type LED lamp radiator which comprises an LED light-emitting panel, a fixed substrate and cooling fins. The LED light-emitting panel is arranged on one side of the fixed substrate, the cooling fins are arranged on the other side of the fixed substrate, and a plurality of cooling fins are regularly arrayed to constitute an intensive cooling fin set. Heat conduction tubes are further arranged in the intensive cooling fin set in a penetrating mode, and refrigerant fluid is sealed and filled in the heat conduction tubes. According to the fin type LED lamp radiator, the LED light-emitting panel is arranged on the fixed substrate which is made of a high heat-conducting property material, heat generated in the working process of an LED light source can be led out quickly, the heat is transmitted to the intensive cooling fin set which is connected to the fixed substrate in an inserting mode, the heat can be transmitted between the adjacent cooling fins through the heat conduction tubes, large-area radiating can be conducted through the cooling fins, the internal temperature rising time of the LED light source can be prolonged, the internal junction temperature of the LED light source can be lowered, and the service life of the light source can be prolonged relatively.

Description

technical field [0001] The invention relates to a finned LED lamp radiator, which belongs to the technical field of LED lamps. Background technique [0002] The heat dissipation of the existing high-power LED street lamp lamp holder basically adopts the method of heat sink to dissipate heat, through natural air cooling and thermal radiation to dissipate heat, especially for integrated LED light sources such as high-power LED street lamps, tunnel lamps, and floodlights, the heat dissipation effect cannot be achieved. Meet the actual use needs. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the above deficiencies in the prior art and provide a finned LED lamp heat sink, which can effectively improve the heat dissipation of the LED lamp and increase the practical life of the LED lamp. [0004] Technical solution: The purpose of the finned LED lamp heat sink of the present invention is achieved in the following way. A fin...
