[0002] Heat dissipation is usually taken into consideration during the design of lamp housings. Traditional bulb-type LED lamp housings mostly adopt a hollow pattern design. However, these hollow heat dissipation LED lamps are not suitable for outdoor or indoor environments with relatively harsh environments. Therefore, the housings of LED lamps suitable for such scenarios are usually sealed.

[0003] Some sealed LED lamps only use one metal side as the heat dissipation shell, which has poor heat dissipation effect. The LED works at high temperature for a long time, resulting in a shortened life of the LED lamp. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an aluminum cup-shaped fin heat sink housing. The device is provided with heat sink fins and guide grooves. The heat sink fins can increase the overall heat dissipation area of ​​the lamp, effectively improving the heat dissipation efficiency of the LED lamp. The provision of the guide grooves can increase the heat transfer area of ​​the heat sink fins, thereby improving the heat transfer efficiency and thereby improving the service life of the LED lamp.

[0005] The device is equipped with a threaded connecting pipe and a non-powered wind hood. The threaded connecting pipe can form a convection channel between the inside of the LED lamp and the outside world. When the temperature inside the LED lamp is higher than that outside, the air pressure inside the LED lamp increases and the gas moves outward, thereby driving the non-powered wind hood to rotate, thereby accelerating the heat dissipation efficiency of the LED lamp.

[0006] The utility model also provides the above-mentioned aluminum cup-shaped fin-type heat dissipation housing, comprising: a fixing sleeve, wherein a connecting thread is provided inside the fixing sleeve, the fixing sleeve is detachably connected to a connecting seat via the connecting thread, the lower side wall of the connecting seat is fixedly connected to a connecting plate, and the lower side wall of the connecting plate is fixedly connected to a plurality of heat dissipation fins;

[0007] A threaded connection pipe is fixedly connected to the middle portion of the lower side wall of the connection plate, a rotating seat is fixedly connected to the lower end of the threaded connection pipe, and a non-powered hood is rotatably connected to the lower end of the rotating seat.

[0008] According to the aluminum cup-shaped fin-type heat dissipation housing, a vent hole is provided in the middle of the connecting plate to facilitate gas flow.

[0009] According to the aluminum cup-shaped fin-type heat dissipation housing, the threaded connection pipe is made of pure copper material, which improves the heat dissipation effect of the threaded connection pipe.

[0010] According to the aluminum cup-shaped fin-type heat dissipation housing, the heat dissipation fins are distributed in a circumferential manner on the outer side wall of the threaded connecting tube, thereby improving the uniformity of the distribution of the heat dissipation fins.

[0011] According to the aluminum cup-shaped fin-type heat dissipation housing, both side walls of the heat dissipation fins are provided with a plurality of guide grooves, which increase the heat transfer area of ​​the heat dissipation fins and thus improve the heat transfer efficiency.

[0012] According to the aluminum cup-shaped fin-type heat dissipation housing, the heat dissipation fins, the connecting plate and the connecting seat are made by an integrated molding technology, thereby improving the overall strength and heat transfer.

[0013] According to the aluminum cup-shaped fin-type heat dissipation housing, a sealing gasket is fixedly connected to the upper side wall of the fixing sleeve, thereby improving the sealing performance of the connection between the fixing sleeve and the lamp.

[0014] According to the aluminum cup-shaped fin-type heat dissipation housing, the shape of the heat dissipation fins is set to be a combination of a rectangle and a quarter circle, which can improve the heat transfer effect.
