Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and more specifically, to a high-efficiency LED fin heat dissipation device. Background Art

[0002] LED lighting fixtures are a general term for LED lamps, which refer to devices that can transmit, distribute and change the light distribution of LED light sources. In addition to the LED light source, they include all parts and components required to fix and protect the LED light source, as well as the circuit accessories necessary to connect to the power supply.

[0003] As LED technology matures, LED lamps are widely used in homes. However, since LED lamps are essentially electroluminescent semiconductor material chips, their light-emitting bodies are small in size, resulting in concentrated heat. Most existing LED lamps often do not have heat dissipation devices, resulting in serious heat accumulation inside the lampshade when the LED lamp is illuminated for a long time. The working characteristics of semiconductor devices are extremely sensitive to temperature. If the heat is not dissipated in time, it will have a significant impact on the luminous efficiency, luminous flux, light color, forward bias voltage and life of the LED. Therefore, it needs to be improved. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a high-efficiency LED fin heat sink, comprising:

[0006] an upper lampshade, wherein a first ring is fixedly mounted on the bottom end of the upper lampshade;

[0007] a heat dissipation mechanism, the heat dissipation mechanism being arranged inside the first ring;

[0008] Among them, the heat dissipation mechanism includes a first threaded ring, the outer surface of the first threaded ring is threadedly sleeved with the inner thread of the first circular ring, the bottom end of the first threaded ring is fixedly installed with a heat dissipation fin, the bottom end of the heat dissipation fin is fixedly installed with a second threaded ring, the outer surface of the second threaded ring is threadedly sleeved with a second circular ring, and the bottom end of the second circular ring is fixedly installed with a lower lamp cover.

[0009] As a preferred technical solution of the present invention, a fixing ring is fixedly installed inside the heat dissipation fin, and the fixing ring is made of metal.

[0010] As a preferred technical solution of the present invention, an insulating block is fixedly sleeved inside the top of the upper lampshade, and a conductive column is fixedly sleeved inside the insulating block.

[0011] As a preferred technical solution of the present invention, a circular plate is fixedly mounted on the bottom end of the conductive column, and a lamp bead is fixedly mounted on the bottom end of the circular plate.

[0012] As a preferred technical solution of the present invention, the top end of the outer surface of the upper lampshade is fixedly sleeved with a threaded sleeve, and the outer surface of the upper lampshade is provided with an arc groove.

[0013] As a preferred technical solution of the present invention, the gaps between the heat dissipation fins are filled with thermally conductive silica gel.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides a first threaded ring, heat dissipation fins and a second threaded ring. Due to the design of the first threaded ring and the second threaded ring, the heat dissipation fins can be conveniently connected to the first circular ring as a whole and the second circular ring as a whole. When the lamp beads generate heat during lighting, the heat will be accumulated inside the upper lampshade and the lower lampshade.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, the utility model provides a high-efficiency LED fin heat dissipation device, including:

[0025] An upper lampshade 1, wherein a first ring 2 is fixedly mounted on the bottom end of the upper lampshade 1;

[0026] A heat dissipation mechanism is provided inside the first ring 2;

[0027] Among them, the heat dissipation mechanism includes a first threaded ring 3, the outer surface of the first threaded ring 3 is threadedly sleeved with the internal thread of the first circular ring 2, the bottom end of the first threaded ring 3 is fixedly installed with a heat dissipation fin 4, the bottom end of the heat dissipation fin 4 is fixedly installed with a second threaded ring 5, the outer surface of the second threaded ring 5 is threadedly sleeved with a second circular ring 6, and the bottom end of the second circular ring 6 is fixedly installed with a lower lamp cover 7.

[0028] Due to the design of the heat dissipation fins 4, the heat inside the upper lampshade 1 and the lower lampshade 7 can be efficiently absorbed, and then the heat is directed to the outside of the upper lampshade 1 and the lower lampshade 7, thereby efficiently dissipating the heat inside the upper lampshade 1 and the lower lampshade 7.

[0029] A fixing ring 8 is fixedly installed inside the heat dissipation fin 4 and is made of metal.

[0030] Due to the design of the fixing ring 8 , the overall structural strength of the heat dissipation fins 4 can be increased without affecting the heat dissipation effect of the heat dissipation fins 4 .

[0031] An insulating block 9 is fixedly sleeved inside the top of the upper lampshade 1 , and a conductive column 10 is fixedly sleeved inside the insulating block 9 .

[0032] Due to the design of the conductive pillar 10 , it can provide good electrical conductivity.

[0033] A circular plate 11 is fixedly mounted on the bottom end of the conductive column 10 , and a lamp bead 12 is fixedly mounted on the bottom end of the circular plate 11 .

[0034] When the conductive column 10 is in contact with the power source, the conductive column 10 will transmit electrical energy to the lamp bead 12 through the circular plate 11, and the lamp bead 12 will illuminate.

[0035] A threaded sleeve 13 is fixedly sleeved on the top end of the outer surface of the upper lampshade 1 , and an arc-shaped groove 14 is formed on the outer surface of the upper lampshade 1 .

[0036] Due to the design of the threaded sleeve 13, the upper lampshade 1 as a whole can be conveniently connected to the power supply. Due to the design of the arc groove 14, the surface friction of the upper lampshade 1 can be increased while enhancing the overall aesthetics of the upper lampshade 1.

[0037] The gaps between the heat dissipation fins 4 are filled with thermally conductive silica gel.

[0038] Due to the filling of the thermal conductive silicone grease, the heat dissipation efficiency of the heat dissipation fins 4 can be enhanced, and mosquitoes can be prevented from entering the interior of the upper lampshade 1 and the lower lampshade 7 through the gaps between the heat dissipation fins 4 .

[0039] The working principle and use process of this utility model:

[0040] Due to the design of the first threaded ring 3 and the second threaded ring 5, the heat dissipation fins 4 can be conveniently connected to the first circular ring 2 and the second circular ring 6 as a whole. Due to the design of the fixing ring 8, the structural strength of the heat dissipation fins 4 can be enhanced. Due to the design of the threaded sleeve 13, the upper lampshade 1 can be conveniently connected to the power supply as a whole. When the conductive column 10 is in contact with the power supply, the current will pass through the conductive column 10 and the circular plate 11 to the interior of the lamp bead 12. At this time, the lamp bead 12 will be illuminated. When the lamp bead 12 is always on, a large amount of heat will be generated. Due to the design of the heat dissipation fins 4, this heat will be absorbed by the heat dissipation fins 4 and then directed to the outside of the upper lampshade 1 and the lower lampshade 7 by the heat dissipation fins 4, thereby achieving the function of efficient heat dissipation inside the upper lampshade 1 and the lower lampshade 7. In addition, since the gaps between the heat dissipation fins 4 are filled with thermally conductive silicone, these thermally conductive silicones will enhance the heat absorption effect of the heat dissipation fins 4, and the thermally conductive silicone can also prevent mosquitoes from entering the interior of the upper lampshade 1 and the lower lampshade 7.
