Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a high-power LED lamp with a built-in heat dissipation structure. Background Technology

[0002] LED lights, short for light-emitting diode lights, are light sources made using semiconductor materials. Unlike traditional incandescent or fluorescent lamps, LED lights release energy when electrons and holes recombine in a semiconductor when an electric current is applied. This energy is expressed as light, thus achieving the illumination function.

[0003] However, in existing technologies, traditional high-power LED lamps often accumulate a large amount of heat inside the lamp housing after prolonged operation. This heat accumulation not only reduces the lifespan of the light source but may also affect the overall performance and stability of the lamp. Most of these LED lamps use passive cooling methods to address this heat issue, that is, by setting up structures such as heat sinks to allow heat to dissipate naturally. However, when the internal temperature of the lamp housing is high, passive cooling methods alone are often insufficient to achieve the desired cooling effect, resulting in a significant decrease in heat dissipation efficiency. Therefore, we provide a high-power LED lamp with a built-in heat dissipation structure. Utility Model Content

[0004] The purpose of this invention is to provide a high-power LED lamp with a built-in heat dissipation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-power LED lamp with a built-in heat dissipation structure, comprising: a heat dissipation mechanism, the heat dissipation mechanism including a lamp housing, a first heat dissipation shell and a second heat dissipation shell respectively provided at both ends of the lamp housing, heat dissipation grooves are arranged in a circular array on the outside of the first heat dissipation shell and the second heat dissipation shell, a bracket is provided inside the first heat dissipation shell and the second heat dissipation shell, a motor is provided in each of the two brackets, a cooling fan is provided at the output end of each of the two motors, a dustproof net is provided on the side of the first heat dissipation shell and the second heat dissipation shell away from the lamp housing, a cavity is provided inside the lamp housing, and a protective mechanism is provided on the side of the first heat dissipation shell and the second heat dissipation shell away from the lamp housing.

[0006] As a further preferred embodiment of this technical solution, the protective mechanism includes a protective shell, and four locking blocks are fixedly connected to the side of the protective shell near the first heat dissipation shell. The first heat dissipation shell and the second heat dissipation shell each have four fixing slots at the ends away from the lamp shell, and the locking blocks are engaged in the fixing slots.

[0007] As a further preferred embodiment of this technical solution, a lamp bead encapsulation plate is fixedly installed inside the cavity of the lamp housing, and lamp bead bodies are provided on both sides of the lamp bead encapsulation plate.

[0008] As a further preferred embodiment of this technical solution, a wire is provided at the port of the lamp bead encapsulation board, the wire extends to the outside of the lamp housing, and a hanging ring is fixedly connected to the top of the lamp housing.

[0009] As a further preferred embodiment of this technical solution, a first heat sink and a second heat sink are fixedly connected to both ends of the lamp housing, and a bracket is fixedly connected inside both the first heat sink and the second heat sink.

[0010] As a further preferred embodiment of this technical solution, the central part of the bracket is fixedly connected to the outside of the motor, and a cooling fan is fixedly connected to the output end of the motor.

[0011] As a further preferred embodiment of this technical solution, dustproof nets are fixedly connected to the side of the first and second heat dissipation shells away from the lamp housing.

[0012] This utility model provides a high-power LED lamp with a built-in heat dissipation structure, which has the following beneficial effects:

[0013] (1) By starting the motors inside the first heat sink and the second heat sink, the two motors will drive the connected cooling fans to rotate. Since the air vent of the cooling fan in the first heat sink faces the outside, the cooling fan will draw out the heat accumulated in the lamp housing and discharge it to the outside environment after it rotates. The air vent of the cooling fan in the second heat sink faces the cavity. When the cooling fan rotates, it can draw out the cold air in the outside environment and blow it into the cavity, thereby cooling down the LED lamp components in the lamp housing. Therefore, the two cooling fans in the same direction will bring ventilation to the lamp housing and accelerate the heat dissipation efficiency of the heat accumulated in the lamp housing.

[0014] (2) The present invention can protect the cooling fan and motor inside the first heat sink and the second heat sink by providing protective shells at one end of the first heat sink and the second heat sink respectively, thereby extending the service life of the heat sink components. The protective shell can be fixedly attached to the heat sink by the provided clip. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a high-power LED lamp with a built-in heat dissipation structure includes: a heat dissipation mechanism 1, which includes a lamp housing 11. A first heat dissipation shell 12 and a second heat dissipation shell 19 are respectively provided at both ends of the lamp housing 11. Heat dissipation grooves 13 are arranged in a circular array on the exterior of both the first and second heat dissipation shells 12 and 19. A support 14 is provided inside both the first and second heat dissipation shells 12 and 19. A motor 15 is installed inside each of the two support 14. A cooling fan 16 is provided at the output end of each of the two motors 15. A dustproof mesh 17 is provided on the side of both the first and second heat dissipation shells 12 and 19 away from the lamp housing 11. A cavity 18 is formed inside the lamp housing 11, and a lamp bead encapsulation plate 31 is fixedly installed in the cavity 18. The lamp bead encapsulation plate 31 has lamp bead bodies 32 on both sides. A wire 33 is provided at the port of the lamp bead encapsulation plate 31 and extends to the outside of the lamp housing 11. A hanging ring 34 is fixedly connected to the top of the lamp housing 11. A first heat sink 12 and a second heat sink 19 are fixedly connected to both ends of the lamp housing 11. A bracket 14 is fixedly connected inside the first heat sink 12 and the second heat sink 19. The center of the bracket 14 is fixedly connected to the outside of the motor 15. A cooling fan 16 is fixedly connected to the output end of the motor 15. A dustproof net 17 is fixedly connected to the side of the first heat sink 12 and the second heat sink 19 away from the lamp housing 11. A protective mechanism 2 is provided at the end of the first heat sink 12 and the second heat sink 19 away from the lamp housing 11.

[0024] In this embodiment, when the high-power LED lamp is used for a long time, the heat generated will accumulate inside the lamp housing 11. To prevent the accumulated heat from affecting the LED bead packaging board 31, the motors 15 inside the first heat sink 12 and the second heat sink 19 can be activated. The two motors 15 will then drive the connected cooling fans 16 to rotate. Specifically, the air vents of the cooling fans 16 inside the first heat sink 12 face outwards. The rotation of the cooling fans 16 will draw the heat accumulated inside the lamp housing 11 and expel it to the outside. In the environment, the air vent of the cooling fan 16 inside the second heat sink 19 faces the cavity 18. Specifically, when the cooling fan 16 rotates, it can draw in the cold air from the outside environment and blow it into the cavity 18 to dissipate heat and cool down the LED components inside the lamp housing 11. Therefore, the two cooling fans 16 in the same direction will bring ventilation to the lamp housing 11 and accelerate the heat dissipation efficiency of the lamp housing 11. In addition, the dustproof net 17 can prevent dust in the outside air from entering the lamp housing 11 and affecting the LED bead encapsulation board 31.

[0025] like Figures 1-4 As shown, the protective mechanism 2 includes a protective shell 21. Four locking blocks 22 are fixedly connected to the side of the protective shell 21 near the first heat dissipation shell 12. The first heat dissipation shell 12 and the second heat dissipation shell 19 are each provided with four fixing slots 23 at the ends away from the lamp shell 11. The locking blocks 22 are engaged in the fixing slots 23.

[0026] In this embodiment, the protective shells 21 provided at one end of the first heat sink 12 and the second heat sink 19 can protect the heat sink fan 16 and the motor 15 inside them, extending the service life of the heat dissipation components. The protective shells 21 can be fixedly snapped onto the heat sink by the provided clips 22.

[0027] This utility model provides a high-power LED lamp with a built-in heat dissipation structure, and its specific working principle is as follows:

[0028] When this high-power LED lamp is used for a long time, it will generate a lot of heat. If this heat is not dissipated in time, it will accumulate inside the lamp housing, which may adversely affect the internal LED chip encapsulation board 31. Therefore, the motors 15 inside the first heat sink 12 and the second heat sink 19 can be activated. The two motors 15 will then drive the connected cooling fans 16 to rotate. Specifically, the cooling fan 16 located in the first heat sink 12 is set to rotate facing the external environment. This means that once activated, the cooling fan 16 will start working, extracting the heat accumulated inside the lamp housing 11 and dissipating it to the surrounding environment. The air is drawn into the surrounding environment to achieve the purpose of cooling. At the same time, a cooling fan 16 rotating in the same direction is also installed in the second heat sink 19. However, unlike the former, this cooling fan 16 blows towards the cavity 18. Its function is to draw in cooler air from the outside and send it into the cavity 18 to directly cool the LED components. With the two cooling fans rotating in the same direction but with different functions working together, not only can the air circulation inside the entire lamp structure be significantly improved, but the heat dissipation efficiency can also be greatly enhanced, ensuring that the LED light source can maintain good performance and long life even under long-term use conditions.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
