Description

Technical Field

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

[0002] LED lamp is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. Due to its own high brightness, it converts light energy into heat energy to make it generate heat. In order to avoid high temperature affecting the service life and luminous effect of LED lamps, it is generally used in conjunction with a heat dissipation structure.

[0003] According to a publicly disclosed LED light strip with a heat dissipation protection structure (Announcement No.: CN218846067U), the above application utilizes a rotating motor and a rotating shaft to rotate in coordination, controls the rotating motor to drive the heat dissipation fan to rotate through the rotating shaft, and discharges the heat emitted by the light strip through the rotation of the heat dissipation fan, thereby achieving the heat dissipation effect.

[0004] However, in actual use of the above-mentioned equipment, since the cooling fan is arranged above the light strip, the cold air generated by the cooling fan can only be blown downward to the upper surface of the light strip, resulting in convection after collision with the upper surface of the light strip, causing the hot wind to be unable to continue to flow downward and be discharged, affecting the heat dissipation effect. At the same time, the bottom end of the protective cover is a sealed structure, and the hot wind cannot be discharged directly, resulting in heat accumulation, which still affects the service life of the LED lamp. In view of this, we propose an LED lamp with a heat dissipation structure. Utility Model Content

[0011] Preferably, the center of the bottom surface of the circular plate is fixedly connected to the top of the lamp body.

[0012] Preferably, the conical air guide tube is located directly below the heat dissipation fan.

[0013] Preferably, an annular bracket is fixedly mounted on the outer wall surface of the lampshade, and an annular filter plate is arranged on the upper surface of the annular bracket. The annular filter plate can be directly replaced from the annular bracket, so that maintenance is convenient.

[0015] Compared with the prior art, the utility model provides an LED lamp with a heat dissipation structure, which has the following beneficial effects:

At the same time, through the cooperation of the set support rod, the light shield and the soft light plate, the hot wind can be discharged to the outside through the bottom of the lampshade, avoiding the bottom of the lampshade being a whole so that the heat cannot be discharged.

[0017] 2. The LED lamp with a heat dissipation structure can filter the gap between the light shield and the lampshade through the annular bracket and the annular filter plate, thereby preventing external dust and impurities from entering the interior of the lampshade through the gap between the light shield and the lampshade and adhering to the soft light plate to affect the light transmission performance.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an LED lamp with a heat dissipation structure, comprising a lampshade 1, an air inlet 2 is provided on the outer wall surface of the upper end of the lampshade 1, a heat dissipation fan 3 is fixedly installed on the inner top surface of the lampshade 1, a lamp body 4 is arranged inside the lampshade 1, and when the lamp body 4 is started, the heat dissipation fan 3 will automatically start to blow air to dissipate heat from the lamp body 4 to prevent the lamp body 4 from overheating and affecting the performance and service life, and a heat dissipation component is arranged inside the lampshade 1.

[0023] The heat dissipation component includes: a circular plate 501, an externally inclined air guide cover 505 and a support rod 506. The circular plate 501 is arranged inside the lampshade 1. The center of the bottom surface of the circular plate 501 is fixedly connected to the top of the lamp body 4. A fixing rod 502 is fixedly installed on the outer wall surface of the circular plate 501. The end of the fixing rod 502 away from the circular plate 501 is fixedly connected to the inner wall of the lampshade 1. The fixing rod 502 can fix the circular plate 501 inside the lampshade 1. A conical air guide tube 503 is fixedly installed on the upper surface of the circular plate 501. The conical air guide tube 503 can guide the cold air blown out by the heat dissipation fan 3 so that the cold air blows down the lower outer side. The conical air guide tube 503 is located directly below the heat dissipation fan 3.

[0024] An inner inclined wind guide cover 504 is fixedly installed on the bottom surface of the circular plate 501, and an outer inclined wind guide cover 505 is fixedly installed on the inner wall surface of the lampshade 1. After being guided by the conical wind guide tube 503, the cold air will enter the gap between the inner inclined wind guide cover 504 and the outer inclined wind guide cover 505, and then will be blown to the outside of the lamp body 4 along the outer wall of the inner inclined wind guide cover 504 and the inner wall of the outer inclined wind guide cover 505, so as to avoid convection caused by only blowing to the upper surface of the lamp body 4, so that the hot wind cannot be blown downward, affecting the heat dissipation efficiency.

[0025] The support rod 506 is fixedly installed on the outer surface of the lampshade 1, and a shading cover 507 is fixedly installed on the end of the support rod 506 away from the lampshade 1, and a soft light plate 508 is fixedly installed on the bottom surface of the shading cover 507. The connection between the shading cover 507 and the soft light plate 508 is a rounded structure, and the soft light plate 508 is a conical structure. When the cold wind passes through the lamp body 4 to take away the heat and continues to blow downward, it will reach the soft light plate 508 downward, flow outward along the upper inclined surface of the soft light plate 508, and flow along the rounded connection with the shading cover 507 to the gap between the shading cover 507 and the lampshade 1, and finally flow out to the outside to complete the heat dissipation flow.

[0026] An annular bracket 601 is fixedly installed on the outer wall surface of the lampshade 1, and an annular filter plate 602 is arranged on the upper surface of the annular bracket 601. The outer wall of the annular filter plate 602 fits with the outer wall of the lampshade 1 and the inner wall of the light shield 507. The annular filter plate 602 can filter the gap between the light shield 507 and the lampshade 1 to prevent dust and impurities in the outside air from entering the interior of the lampshade 1 and falling on the soft light plate 508 to affect the light transmission performance.

[0027] In the utility model, when in use, the heat dissipation fan 3 will be started synchronously when the lamp body 4 is started. At this time, the heat dissipation fan 3 generates cold wind which is blown onto the conical air guide tube 503, and flows downward and outward along the inclined surface of the conical air guide tube 503 into the gap between the inner inclined air guide cover 504 and the outer inclined air guide cover 505, and then blows toward the outside of the lamp body 4 through the guidance of the inner inclined air guide cover 504 and the outer inclined air guide cover 505, thereby avoiding that the generated cold wind can only be blown to the upper surface of the lamp body 4, resulting in convection so that the wind with heat cannot be discharged, affecting the heat dissipation effect, and then the wind with the heat of the lamp body 4 is blown to the soft light plate 508, along the inclined surface of the soft light plate 508 into the gap between the light shielding cover 507 and the lampshade 1, and finally flows out to the outside to complete the heat dissipation process.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
