[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] See also Figure 1-4A heat dissipation structure based on a crystal downlight includes a lamp housing 1, a protective cover 2, a base 3, a radiator 4 and a mounting fixture. The top of the lamp housing 1 is installed with a protective cover 2, the bottom of the lamp housing 1 is provided with the base 3, a crystal lens 5 is provided inside the protective cover 2, and an LED lamp bead 6 is provided inside the crystal lens 5. A heat dissipation aluminum plate 7 is installed on the bottom wall of the base 3. The base 3 is connected to the radiator 4 through the mounting fixture. The mounting fixture includes a rectangular block 8, a rectangular groove 9, a bidirectional screw 10, a slider 11, a connecting plate 12, a clamping plate 13, an annular groove 14 and a drive shaft 15. One end of the radiator 4 is externally The rectangular block 8 is installed on the wall, and the side wall of the rectangular block 8 is provided with the rectangular groove 9. The bidirectional screw 10 is rotatably installed in the rectangular groove 9. The left and right ends of the bidirectional screw 10 are threadedly installed with the slider 11. The side wall of the slider 11 away from the end of the rectangular groove 9 is fixedly installed with the connecting plate 12. The two groups of connecting plates 12 are installed with the clamping plate 13 at one end away from the slider 11. The side wall of the base 3 is provided with an annular groove 14, and the annular groove 14 is adapted to the clamping plate 13. A temperature sensor 16 is installed in the middle of the rectangular groove 9, and the temperature sensor 16 is electrically connected to the radiator 4. One end of the bidirectional screw 10 passes through the side wall of the rectangular groove 9 and is installed with the driving shaft 15. In this embodiment, when in use, the LED lamp bead 6 is installed inside the crystal lens 5. When emitting light, the light is diffused through the crystal lens 5 to form a beautiful lighting effect. The protective cover 2 plays a protective role to prevent external dust and foreign matter from entering the interior of the lamp housing 1, and also contributes to the beauty. The main function of the heat dissipation aluminum plate 7 is to conduct the heat generated by the LED lamp bead 6. When the radiator 4 needs to be installed on the base 3, first, the lamp housing 1 drives the base 3 to be placed between the two sets of clamping plates 13, and the bidirectional screw 10 is driven to rotate by rotating the driving shaft 15. The rotation of the bidirectional screw 10 The two sliders 11 move in opposite directions, thereby driving the connecting plate 12 to move from both ends to the middle, so that the clamping plate 13 clamps the annular groove 14 on the outer wall of the base 3. The temperature sensor 16 monitors the temperature around the base 3 and transmits the signal to the radiator 4. If the temperature exceeds the preset threshold, the heat is taken away by the fan of the radiator 4, and the base 3 and the heat dissipation aluminum plate 7 are physically dissipated to ensure the heat dissipation effect. The heat generated by the LED lamp beads 6 is conducted to the heat dissipation aluminum plate 7 on the base 3 through the lamp housing 1. The base 3 is connected to the radiator 4 through a mounting fixture to ensure a stable connection between the base 3 and the radiator 4, thereby ensuring a good heat dissipation effect.

[0025] During actual use, the heat dissipation effect of the lamp housing 1 is further improved. In this embodiment, the outer wall of the lamp housing 1 is provided with a plurality of heat dissipating fins 17 in a ring shape. The heat dissipating fins 17 arranged in a ring shape can significantly increase the heat dissipation area of the lamp housing 1, so that more heat can be dissipated into the surrounding air through the fins, thereby improving the heat dissipation efficiency. The heat dissipating fins 17 arranged in a ring shape can ensure that the heat is evenly distributed on the outer surface of the entire lamp housing 1, avoiding local overheating and making the heat dissipation more uniform. By increasing the number and area of the heat dissipating fins 17, the contact area between the air and the surface of the lamp housing 1 can be increased, thereby accelerating the conduction and convection of heat and further improving the heat dissipation effect.

[0026] During actual use, the dust-proof effect of the radiator 4 is further improved. In this embodiment, dust covers 18 are installed on the upper and lower side walls of the radiator 4. The dust cover 18 can effectively prevent external dust from entering the interior of the radiator 4, reduce the impact of dust on the internal components of the radiator 4, and thus improve the dust-proof effect of the radiator 4. By reducing the entry of dust into the interior of the radiator 4, dust can be prevented from clogging the heat sink or fan blades, reducing the wear of the internal parts of the radiator 4, thereby extending the service life of the radiator 4.

[0027] In actual use, in order to further facilitate the rotation of the drive shaft 15, in this embodiment, a knob 19 is provided on the end of the drive shaft 15. Through the knob 19, the user can more easily apply a greater rotational force, thereby making the drive shaft 15 easier to rotate when a larger torque is required.

[0028] During actual use, the clamping and fixing effect of the clamping plate 13 is further improved. In this embodiment, springs 20 are installed on the left and right ends of the rectangular groove 9 and are sleeved on the outer wall of the bidirectional screw 10. The other end of the spring 20 is fixedly connected to the ends of the two groups of sliders 11 that are away from each other. The function of the spring 20 is to provide a pressure that is always toward the center, so that the slider 11 always maintains a threaded connection with the bidirectional screw 10, thereby enhancing the clamping force of the clamping plate 13 on the base 3 and ensuring the stability of the clamping.

[0029] Preferably, in this embodiment, the clamping plate 13 is of arc-shaped design. The arc-shaped design enables the clamping plate 13 to better fit the contour of the annular groove 14, increases the contact area between the clamping plate 13 and the annular groove 14, thereby improving the stability of clamping and preventing loosening or falling off during use.

[0030] During actual use, in order to further improve the anti-slip property of the knob 19, in this embodiment, an anti-slip strip 21 is installed on the outer wall of the knob 19. The anti-slip strip 21 can increase the friction coefficient of the surface of the knob 19, so that the user can hold the knob 19 more easily during operation, thereby improving the feel and comfort during operation.

[0031] Preferably, in this embodiment, the height of the connecting plate 12 is greater than the height of the heat dissipation aluminum plate 7, so that there is space between the radiator 4 and the heat dissipation aluminum plate 7 to facilitate air circulation.

The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.
