DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0022] See also Figure 1-4 , this patent provides a technical solution: an LED lamp with enhanced heat dissipation, including a lamp housing 1, a circuit board 2 and an LED lamp bead 3, the inner wall of the lamp housing 1 is installed with the circuit board 2, the LED lamp bead 3 is installed below the circuit board 2, the LED lamp bead 3 is electrically connected to the circuit board 2, the upper wall of the lamp housing 1 is installed with a spiral lamp holder 4, the upper wall of the circuit board 2 is installed with a connecting tube 5, the circuit board 2 is electrically connected to the spiral lamp holder 4;

[0023] The spiral lamp holder 4 is screwed into the external lamp holder and connected to the external power supply, so that the LED lamp bead 3 is powered on and lit. When the LED lamp bead 3 is lit, the micro motor 16 is started, and the rotating ring 7 is driven to rotate through the cooperation of the main gear 17 and the auxiliary gear 18, so that the air flow in the lamp housing 1 is accelerated through the arc-shaped fan blades 8, the heat dissipation is accelerated, the heat dissipation effect is improved, and the service life of the LED lamp is effectively extended;

[0024] The upper wall of the circuit board 2 is provided with heat dissipation fins 6, the outer side of the connecting tube 5 is sleeved with a rotating ring 7, and the outer side wall of the rotating ring 7 is provided with arc-shaped fan blades 8;

[0025] The heat dissipation fin 6 comprises a heat conducting plate 61, a fin 62, a sliding ring 63, a support rod 64 and a brush 65. The heat conducting plate 61 is mounted on the upper wall of the circuit board 2. The fin 62 is mounted on the upper wall of the heat conducting plate 61. The sliding ring 63 is sleeved on the outside of the fin 62. The sliding ring 63 can slide up and down on the outside of the fin 62. The support rod 64 is mounted on the inner wall of the sliding ring 63. The side wall of the support rod 64 is mounted with a brush 65.

[0026] The heat conducting plate 61 can transfer the heat of the circuit board 2 to the fins 62, thereby increasing the contact area with the air, thereby achieving the purpose of strong heat dissipation;

[0027] Because the vents 15 are arranged on the side wall of the lamp housing 1 of the device, the heat inside the lamp can be dissipated, but at the same time, the external dust can easily enter the lamp housing 1, causing the fins 62 to be contaminated, and the dust will affect the heat dissipation effect of the fins 62;

[0028] Therefore, the device is provided with a sliding ring 63 on the outside of the fin 62. Through the sliding ring 63, the dust attached to the fin 62 can be cleaned by the bristles 65 on the support rod 64. After the dust is cleaned, it will be discharged from the lamp housing 1 through the ventilation hole 11 along with the airflow generated by the arc-shaped fan blades 8.

[0029] Specifically, the lamp housing 1 includes an upper housing 11, a lower housing 12 and a lampshade 13. The spiral lamp holder 4 is installed on the upper wall of the upper housing 11. The upper wall of the upper housing 11 is provided with a socket 9, and a bolt 10 is inserted and installed in the socket 9. The upper wall of the lower housing 12 is provided with a threaded hole 14, and the bolt 10 is screwed and installed in the threaded hole 14. The side wall of the lower housing 12 is provided with a ventilation hole 15. The lower wall of the lower housing 12 is inserted and installed with a lampshade 13. The lampshade 13 covers the outside of the LED lamp bead 3. The heat dissipation fins 6 and the rotating ring 7 are both located on the inner side of the lower housing 12.

[0030] Specifically, a micro motor 16 is inserted into the lower wall of the upper housing 11, and the micro motor 16 is electrically connected to the spiral lamp holder 4. A main gear 17 is installed at the output end of the micro motor 16, and a sub gear 18 is installed on the outer side of the rotating ring 7. The main gear 17 is meshed with the sub gear 18.

[0031] The micro motor 16 can drive the main gear 17 to rotate, so that the rotating ring 7 drives the arc-shaped fan blades 8 to rotate under the cooperation of the main gear 17 and the auxiliary gear 18, thereby accelerating the air flow speed in the lamp housing 1.

[0032] Specifically, a slide groove 19 is provided on the side wall of the lower shell 13, a slide rod 20 is slidably installed in the slide groove 19, one end of the slide rod 20 located inside the lower shell 13 is installed on the side wall of the slide ring 63, and one end of the slide rod 20 located outside the lower shell 13 is installed with a push block 21;

[0033] By pushing the external push block 21 , the internal sliding ring 63 can be driven to move up and down through the sliding rod 20 , so that the dust on the fins 62 can be cleaned through the bristles 65 .

[0034] Specifically, a positioning groove 22 is formed on the inner wall of the slide groove 19, and a limit plate 23 is installed on the outer side of the slide rod 20. The limit plate 23 is inserted into the positioning groove 22, and the limit plate 23 can slide in the positioning groove 22;

[0035] By providing the limiting plate 23 and the positioning groove 22 , it is possible to prevent the slide rod 20 from tilting, which would result in the slide ring 63 being unable to move up and down.

[0036] Specifically, the bristles 65 are high temperature resistant nylon threads.

[0037] Working principle: The spiral lamp holder 4 is screwed into the external lamp holder and connected to the external power supply, so that the LED lamp bead 3 is powered on and lit. When the LED lamp bead 3 is lit, the micro motor 16 is started, and the rotating ring 7 is driven to rotate through the cooperation of the main gear 17 and the auxiliary gear 18, so that the air flow in the lamp housing 1 is accelerated through the arc-shaped fan blades 8, thereby accelerating the heat dissipation;

[0038] After the device has been used for a period of time, the staff pushes the push block 21 to drive the internal sliding ring 63 to slide up and down on the outside of the fin 62, and uses the bristles 65 on the support rod 64 to clean the dust attached to the fin 62. After the dust is cleaned off, it will be discharged from the lamp housing 1 through the ventilation hole 11 along with the air flow generated by the arc-shaped fan blades 8, thereby ensuring the heat dissipation effect of the fin 62.
