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.

[0021] Embodiment: A dimming LED lamp, such as Figures 1-4 As shown, it includes a lamp housing 1, the lower end of the outer side of the lamp housing 1 is threadedly connected to a fixed cover 3, the inner cavity of the lamp housing 1 is fixedly connected to a limiting inner ring 12, a reflector 6 is provided between the limiting inner ring 12 and the fixed cover 3, and a connecting component 7 is plugged into the upper end of the lamp housing 1, and a heat dissipation component 8 is installed in the connecting component 7.

[0022] like Figure 2 and Figure 3 As shown, the connecting component 7 includes a breathable cover 71 inserted into the inner cavity of the lamp housing 1, the lower end of the breathable cover 71 is fixedly connected to a heat conducting plate 72 that is clamped to the reflector 6, the upper layer of the inner wall of the breathable cover 71 is provided with a dustproof net 75, and the upper layer of the outer side of the breathable cover 71 is provided with multiple groups of heat dissipation holes 73.

[0023] The heat dissipation assembly 8 includes a drive motor 81 and a fixed sleeve 83. The drive motor 81 is installed on the upper surface of the breathable cover 71. The output shaft of the drive motor 81 is installed with a rotating shaft 82. The fixed sleeve 83 is fixedly installed on the outside of the rotating shaft 82. A plurality of heat dissipation fan blades 84 are provided on the outside of the fixed sleeve 83. The heat dissipation fan blades 84 accelerate the air circulation speed in the breathable cover 71 and improve the heat dissipation efficiency of the LED lamp.

[0024] Multiple groups of heat dissipation blades 84 are arranged at equal angles, and the cross-section of the heat dissipation blades 84 is arranged in a wavy shape. The height of the heat dissipation blades 84 is less than the height of the air permeable cover 71 located outside the lamp housing 1, that is, less than the height of the air permeable cover 71 leaking out of the lamp housing 1. The bottom layer of heat dissipation holes 73 is arranged in the inner cavity of the lamp housing 1 to facilitate the discharge of heat from the inner cavity of the lamp housing 1 and improve the heat dissipation efficiency.

[0025] An LED lamp board 10 is installed on the lower surface of the heat conducting plate 72. A plurality of groups of LED lamp beads 11 are arranged on the lower surface of the LED lamp board 10. The plurality of LED lamp beads 11 are arranged in a rectangular array. The arrangement of the LED lamp beads 11 ensures the uniformity of the light source illumination.

[0026] A dimmer 15 is provided on the upper surface of the heat conducting plate 72. A plurality of groups of first heat sinks 9 are provided on the upper surface of the heat conducting plate 72. The plurality of first heat sinks 9 are arranged at equal angles, and the dimmer 15 is arranged between the plurality of first heat sinks 9. The heat dissipation effect of the heat conducting plate 72 is accelerated by the first heat sink 9, thereby improving the heat dissipation efficiency of the LED lamp beads 11 and improving the service life of the LED lamp beads 11.

[0027] like Figure 2 and Figure 4 As shown, the upper surface of the reflector 6 is open and conical, and multiple groups of connecting blocks 14 are fixedly connected to the upper surface of the reflector 6. The lower surface of the heat conducting plate 72 is provided with connecting holes 74 for the multiple groups of connecting blocks 14 to be plugged in. The connecting blocks 14 are plugged into the connecting holes 74 to facilitate the fixation of the reflector 6, thereby improving the stability of the overall installation of the LED lamp.

[0028] like Figure 4 As shown, multiple groups of second heat sinks 13 are fixedly connected to the lower surface of the limiting inner ring 12. The multiple groups of second heat sinks 13 are all arranged in a triangular shape. The inclined surfaces of the multiple groups of second heat sinks 13 are all in contact with the outer wall of the reflector 6. The multiple groups of second heat sinks 13 are used to facilitate the absorption of heat on the reflector 6, thereby further improving the heat dissipation efficiency of the LED lamp.

[0029] A wire 16 is provided on the upper surface of the air cover 71, and a torsion spring seat 4 is installed at the upper ends of both sides of the lamp housing 1.

[0030] When in use, the LED lamp beads 11 emit light and generate heat. The heat is absorbed by the heat conducting plate 72 through the LED lamp board 10, and then is conducted out through multiple groups of first heat sinks 9. At the same time, multiple groups of second heat sinks 13 conduct the heat on the reflector 6, so that the heat is directed between the lamp housing 1 and the air breathable cover 71. The driving motor 81 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the fixed sleeve 83 to rotate, so that the multiple groups of heat dissipation fan blades 84 rotate to accelerate the air circulation speed inside the air breathable cover 71, and accelerate the efficiency of air alternation inside and outside the air breathable cover 71, so that outside air enters the air breathable cover 71 to exchange out the air with heat, thereby improving the heat dissipation efficiency of the LED lamp and extending the service life of the LED lamp. At the same time, the dustproof net 75 can prevent external dust from being introduced into the air breathable cover 71 during the air alternation time, thereby preventing dust from affecting the LED lamp. At the same time, during the air alternation process, the probability of dust clogging the holes of the dustproof net 75 is reduced, further improving the overall heat dissipation effect of the LED lamp.

[0031] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
