Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of LED lamps, in particular to a heat dissipation structure of a low-power LED lamp. Background Art

[0002] LED is a semiconductor device that can convert electrical energy into light energy. LED lights emit light through semiconductor materials when powered on. It has the advantages of high efficiency, energy saving, and long life. Therefore, it is widely used in the field of modern lighting. LED will generate a certain amount of heat when working. The main reasons include the heat generated when electrical energy is converted into light energy and the resistance of the internal materials of the LED. If the heat dissipation of the LED lamp group is not good, the temperature is too high, which will have a negative impact on the performance and life of the LED, and may even cause damage to the LED components. Therefore, in order to ensure the normal operation of the LED and extend the service life of the LED, effective heat dissipation must be carried out.

[0003] At present, an existing device (such as patent number: CN220186756U) discloses a heat dissipation LED lamp, which drives the inlet fan blades to rotate through the air inlet motor, blows the external air into the lampshade through the right hole at the bottom of the LED lamp holder after passing through the air inlet filter, and then drives the outlet fan blades to rotate through the air outlet motor, sucks the heat in the lampshade through the left hole at the bottom of the LED lamp holder, blows it out through the air outlet filter, and completes the heat dissipation. This solves the problem that the heat dissipation performance of the existing LED lamp is poor due to the sealing of the lampshade during operation, and the heat generated by the operation of the lamp beads cannot be quickly extracted and subsequently heat-dissipated, which affects the stability of the operation of the lamp beads.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the above device is in use, it is necessary to drive two motors at the same time to complete the circulation and cooling of the air, and the operation of the motor will also generate some heat. At the same time, the motor of the device and the LED lamp group are in the same space. The operation of the motor will affect the heat dissipation efficiency of the LED lamp group, and because of the operation of the dual motors, it will further lead to an increase in energy consumption, which will make the overall energy consumption of the device higher, the environmental protection is poor, and the practicality needs to be improved.

[0024] The embodiment of the present application effectively solves the technical problems of the existing device's lack of environmental protection and practicality by providing a low-power LED lamp's heat dissipation structure. By turning on the motor, the motor's output shaft uses a synchronous belt to slide in the baffle and drive the active bevel gear to rotate, so that the active bevel gear and the driven bevel gear are meshed, and then the driven bevel gear drives the rotating shaft to rotate between the fixed plates, thereby driving the blowing fan blade group to the side of the second through groove to blow out the hot air inside the upper lamp cover, so that the device can drive the air intake fan blade group and the blowing fan blade group to rotate at the same time by turning on one motor, thereby reducing energy consumption to a certain extent and improving environmental protection. By optimizing the structure and layout of the device, the motor is installed in the upper lamp cover and the output shaft of the motor is extended to the straight groove and the circular groove, which can prevent the heat emitted by the motor when working from entering between the upper lamp cover and the lower lamp cover, thereby affecting the heat dissipation of the LED lamp group and improving practicality.

[0028] A synchronous heat dissipation mechanism is fixedly mounted on the upper end of the upper lampshade 11;

[0029] The synchronous heat dissipation mechanism includes a motor 19, the output shaft portion of the motor 19 extends inside the straight groove 14 and the circular groove 18, the output shaft of the motor 19 is rotatably mounted with the upper lampshade 11, and an inlet fan blade group 21 is fixedly mounted on the output shaft of the motor 19. The synchronous heat dissipation mechanism also includes a baffle 22, a fixing plate 23, a rotating shaft 24, a blowing fan blade group 25, a driven bevel gear 26, an active bevel gear 27 and a synchronous belt 28. The baffle 22 is fixedly mounted inside the straight groove 14, the two fixing plates 23 are fixedly mounted inside the straight groove 14, the two fixing plates 23 are on the same side as the second through groove 16, and the rotating shaft 24 is rotatably mounted between the fixing plates 23. By optimizing the structure and layout of the device, the motor 19 is installed on the upper lampshade 11 and the output shaft of the motor 19 is extended to the straight groove 14 and the circular groove 18, so that the heat emitted by the motor when working can be prevented from entering between the upper lampshade 11 and the lower lampshade 12, thereby affecting the heat dissipation of the LED lamp group 13 and improving practicality.

[0030] The fan blade group 25 and the driven bevel gear 26 are both fixedly installed on the circumferential surface of the rotating shaft 24, the rotating shaft 24 is partially exposed outside the fixing plate 23, the fan blade group 25 is located between the fixing plates 23, the driving bevel gear 27 is rotatably installed inside the straight groove 14, the driving bevel gear 27 is meshed with the driven bevel gear 26, the synchronous belt 28 is rotatably installed between the driving bevel gear 27 and the output shaft of the motor 19, the synchronous belt 28 is slidably installed with the baffle 22, and by turning on the motor 19, the output shaft of the motor 19 is synchronously The belt 28 slides in the baffle 22 and drives the active bevel gear 27 to rotate, so that the active bevel gear 27 is meshed with the driven bevel gear 26, and then the driven bevel gear 26 drives the rotating shaft 24 to rotate between the fixed plates 23, thereby driving the blowing fan blade group 25 to blow out the hot air inside the upper lamp cover 11 toward the side of the second through groove 16, so that the device can drive the inlet fan blade group 21 and the blowing fan blade group 25 to rotate together by turning on a motor 19, thereby reducing energy consumption to a certain extent and improving environmental protection.

[0032] The first step is to turn on the LED light group 13 and the motor 19 of the upper lamp cover 11 when in use. At this time, the turning on of the LED light group 13 will make the air between the upper lamp cover 11 and the lower lamp cover 12 have a certain amount of heat. At the same time, the motor 19 will drive the fan blade group 21 to rotate, so that the fan blade group 21 draws in the external cold air through the first through groove 15 into the upper lamp cover 11 and squeezes the hot air between the upper lamp cover 11 and the lower lamp cover 12 into the side of the second through groove 16.

[0033] In the second step, when the output shaft of the motor 19 rotates, the synchronous belt 28 will slide in the baffle 22 and drive the active bevel gear 27 to rotate, so that the active bevel gear 27 is meshed with the driven bevel gear 26, and then the driven bevel gear 26 drives the rotating shaft 24 to rotate between the fixed plates 23, thereby driving the blowing fan blade group 25 to blow toward the side of the second through groove 16, and then the hot air inside the upper lampshade 11 and the lower lampshade 12 is discharged, so as to achieve the effect of circulating heat dissipation and cooling.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
