Referring to fig. 1, a spot lamp with high heat dissipation capability includes: a lamp socket 200, a light emitting element 500, and a heat sink 300; the light-emitting element 500 is arranged in the lamp holder 200, the heat sink 300 is connected with the lamp holder 200, and the light-emitting element 500 is positioned in the heat sink 300; the heat sink 300 is provided with a plurality of heat dissipation fins 350, and the plurality of heat dissipation fins 350 are arranged around the center of the heat sink 300; a spiral air channel 330 is disposed between two adjacent heat dissipation fins 350, and the air channel 330 gradually increases toward a direction away from the light emitting element 500. When the light emitting device 500 operates, heat is generated. Since the light emitting device 500 is located in the heat sink 300, the heat emitted from the light emitting device 500 is transferred to the heat sink 300 and the heat sink 350 on the heat sink 300. The air flow channels 330 may guide air to flow between the heat sinks 350, thereby effectively removing heat from the heat sinks 350. The spiral air channel 330 can effectively increase the air contact area of the heat sink 350, thereby greatly improving the heat dissipation efficiency of the heat sink 350. Meanwhile, the gradual increase of the air flow channel 330 enables air to be better blown into the air flow channel 330 in a direction toward the light emitting element 500, thereby further improving the heat dissipation efficiency of the heat sink 350.

In some embodiments, referring to fig. 2, fins 350 are spiral-lobed. The spiral-vane-shaped heat dissipation fins 350 can guide the air flow to perform spiral motion among the heat dissipation fins 350, so that the contact area between the air flow and the heat dissipation fins 350 is increased, and the heat dissipation effect is greatly increased.

In some embodiments, referring to fig. 1, each of the heat sinks 350 gradually spreads out toward a direction away from the light emitting element 500. The diffusion distribution of the heat sink 350 makes the air channel 330 have a larger air inlet, so that air can flow into the air channel 330, and the heat dissipation efficiency of the heat sink 350 is improved.

Specifically, the respective heat sinks 350 are connected at one end adjacent to the light emitting element 500, and the other ends are diffused apart from each other. Of course, the heat sinks 350 may be connected in other manners, and the specific embodiment may be adjusted according to the actual situation, which is not limited herein.

In some embodiments, referring to fig. 3, the air chamber 370 is provided at the middle of the heat sink 300, the air flow passage 330 communicates with the side of the air chamber 370, and the end of the air chamber 370 communicates with the outside. The wind chamber 370 allows air at the end of the heat sink 300 to flow into the air flow passage 330, thereby further increasing the amount of wind flow between the heat sinks 350, and thus increasing heat dissipation efficiency.

In some embodiments, referring to fig. 2, the heat sink 350 is provided with a vent 355, and the air flow passages 330 are communicated with each other through the vent 355. The ventilation opening 355 allows the air flow passages 330 to communicate with each other, so that the air can flow more smoothly, thereby improving the efficiency of the wind flow in removing heat.

Specifically, the vent 355 is located in the middle of the heat sink 350.

In some embodiments, referring to fig. 2, a connection ring 600 is disposed between the lamp socket 200 and the heat sink 300, and both the lamp socket 200 and the heat sink 300 are detachably connected to the connection ring 600. The connection ring 600 detachably connects the lamp socket 200 and the heat sink 300, so that both the lamp socket 200 and the heat sink 300 can be detached with respect to the connection ring 600, thereby facilitating maintenance or replacement.

In some embodiments, referring to fig. 3, the lamp socket 200 is provided with a mounting groove, and a screw structure 650 is provided between the connection ring 600 and the mounting groove, and the connection ring 600 is mounted in the mounting groove by the screw structure 650. The turnbuckle structure 650 not only can stably and reliably connect the connection ring 600 and the lamp holder 200 to each other, but also can be easily disassembled because the turnbuckle structure 650 can be disassembled by rotating.

In some embodiments, referring to fig. 4, the threading structure 650 includes a threading groove 655 provided on the attachment ring 600, the threading groove 655 having a first inlet 653 and a second inlet 657 provided thereon; a first clamping block is arranged in the mounting groove, and the first clamping block can penetrate through the first inlet 653 and is rotatably clamped into the screwing groove 655; the heat sink 300 is provided with a second latch, and the second latch can pass through the second inlet 657 and rotate to latch into the screw-fastening groove 655. The cooperation of the first latch and the first inlet 653 and the cooperation of the second latch and the second inlet 657 effectively allow the heat sink 300 or the lamp socket 200 to be engaged with the connection ring 600. The screw-fastening groove 655 not only can effectively fasten the heat sink 300 or the lamp holder 200 to the connection ring 600, but also can relatively position the heat sink 300 and the lamp holder 200, thereby improving the mounting accuracy of the heat sink and the lamp holder.

Specifically, a first inlet 653 and a second inlet 657 are respectively located at both ends of the thread-engaging groove 655, the first inlet 653 communicating with the upper end surface of the connection ring 600, and the second inlet 657 communicating with the lower end surface of the connection ring 600.

Specifically, the first inlet 653, the turn-buckle groove 655 and the second inlet 657 are located at the outer circumferential wall of the connection ring 600.

The positioning step can position the light reflecting cup 250, so as to ensure that the light reflecting cup 250 stably converges the light emitted by the light emitting element 500.

Specifically, the positioning step is located at the inner circumferential wall of the connection ring 600.

In some embodiments, referring to fig. 1, the lamp socket 200 is provided with the connection holder 100. The connection holder 100 allows the lamp socket 200 to be mounted to various portions of the outside, thereby facilitating the use of the spot lamp.

Specifically, the connection holder 100 is provided with two clips.
