Description

Technical Field

[0001] This utility model relates to the field of LED lantern technology, specifically an adjustable LED lantern with a heat dissipation structure. Background Technology

[0002] LED lanterns use traditional lanterns (also known as lanterns) as a carrier and LED semiconductor solid-state light-emitting devices as the light source. Because LED lanterns are more aesthetically pleasing when lit up than ordinary LED lights, they are used in parks, squares and commercial districts.

[0003] In pursuit of a more aesthetically pleasing appearance, some existing LED lanterns sacrifice heat dissipation mechanisms to prevent the LEDs from emitting heat. This leads to heat buildup inside the LEDs after continuous operation for a period of time. Using LEDs in such an environment accelerates their aging process, shortening their lifespan. Furthermore, many existing LED lanterns use simple, integrated mounting frames, preventing installers from making precise height adjustments to suit different installation needs, resulting in poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable LED decorative light with a 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:

[0006] An adjustable LED lantern with a heat dissipation structure includes a supporting pole, a base plate, a transparent lampshade, a top plate, an extension plate, and an LED light panel. The extension plate is fixedly connected to the upper side of the annular side of the supporting pole. The top plate is installed below the extension plate, and the base plate is installed below the top plate. A transparent lampshade is installed between the top plate and the base plate. An LED light panel is installed on the upper surface of the base plate. The top plate and the base plate are connected by a connecting screw. Both the top plate and the base plate have heat dissipation components inside, which dissipate heat from the transparent lampshade. A mounting component is provided on the top of the top plate, which is used to mount the top plate below the extension plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] Example 1:

[0026] An adjustable LED lantern with a heat dissipation structure includes a supporting lamp post 1, a base plate 2, a transparent lampshade 3, a top plate 4, an extension plate 5, and an LED light panel 9. The extension plate 5 is fixedly connected to the upper side of the annular side of the supporting lamp post 1. The extension plate 5 is connected to the supporting lamp post 1 by welding. The extension plate 5 can support the mounting components. The top plate 4 is installed below the extension plate 5. The base plate 2 is installed below the top plate 4. The transparent lampshade 3 is installed between the top plate 4 and the base plate 2. The transparent lampshade 3 is made of transparent acrylic. The LED light panel 9 is installed on the upper surface of the base plate 2. The top plate 4 and the base plate 2 are connected by a connecting screw 6. The base plate 2, the transparent lampshade 3, the top plate 4, the connecting screw 6, and the LED light panel 9 constitute the LED lantern.

[0027] Both the lamp top plate 4 and the lamp bottom plate 2 are equipped with heat dissipation components, which are used to dissipate heat inside the transparent lamp cover 3 to prevent heat accumulation inside the transparent lamp cover 3. The top of the lamp top plate 4 is equipped with a mounting component, which not only makes it convenient for installers to install the lamp top plate 4 under the extension plate 5, but also allows installers to fine-tune the height of the lamp top plate 4.

[0028] Both the lower end face of the lamp top plate 4 and the upper end face of the lamp base plate 2 are provided with annular limiting grooves 21, and the annular limiting grooves 21 match the upper and lower end faces of the transparent lamp cover 3. The annular limiting grooves 21 facilitate the upper and lower ends of the transparent lamp cover 3 to be respectively snapped onto the lower end face of the lamp top plate 4 and the upper end face of the lamp base plate 2, avoiding misalignment of the lamp top plate 4 and the lamp base plate 2 during installation. A sealing ring 32 is embedded inside the annular limiting groove 21. The sealing ring 32 is made of silicone rubber. The silicone rubber sealing ring 32 makes the annular limiting groove 21 more airtight, preventing external rainwater or dust from entering the interior through the connection between the transparent lamp cover 3 and the lamp top plate 4 and the lamp base plate 2, causing contamination of the LED lamp panel 9. A colored sticker 31 is provided on the annular side of the transparent lamp cover 3, which can further improve the aesthetics of the transparent lamp cover 3.

[0029] A wire-passing hole 22 is provided on the right side of the lamp base plate 2. The wire-passing hole 22 facilitates the insertion of external wires into the lamp base plate 2 to make electrical connections with the LED lamp panel 9. After the external wires are inserted into the wire-passing hole 22, the installer can use external explosion-proof putty to seal the wire-passing hole 22 to prevent external dust from entering the transparent lamp cover 3 and contaminating the LED lamp panel 9. Both the lamp base plate 2 and the lamp top plate 4 are petal-shaped, which improves their aesthetics. Both the lamp top plate 4 and the lamp base plate 2 are made of aluminum-silicon alloy, which is lightweight, has good thermal conductivity, and also has certain strength, hardness, and corrosion resistance.

[0030] The heat dissipation assembly includes a central heat pipe 71, a heat absorption fin 72, and a bottom heat sink 75. The central heat pipe 71 is located in the middle of the interior of the lamp top plate 4. The central heat pipe 71 is made of aluminum-silicon alloy and has a hollow structure. This hollow structure not only provides good thermal conductivity, allowing it to absorb most of the heat in the central area of ​​the transparent lampshade 3, but also allows external air or rainwater to pass through and cool it down. The tube 71 and the lamp top plate 4 are integrated into one structure. There is no gap between the central heat-conducting tube 71 and the lamp top plate 4, which prevents external rainwater or dust from entering the transparent lamp cover 3 through the connection between the central heat-conducting tube 71 and the lamp top plate 4 and causing contamination of the LED lamp panel 9. Multiple heat-absorbing sheets 72 are fixedly connected to the annular side of the central heat-conducting tube 71. The heat-absorbing sheets 72 are made of aluminum-silicon alloy. The multiple heat-absorbing sheets 72 made of aluminum-silicon alloy can further increase the heat conduction area of ​​the central heat-conducting tube 71.

[0031] Multiple bottom heat sinks 75 are fixedly connected to the bottom of the lamp base plate 2. The bottom heat sinks 75 and the lamp base plate 2 are an integral structure. The bottom heat sinks 75 are made of aluminum-silicon alloy. The multiple bottom heat sinks 75 made of aluminum-silicon alloy can further increase the heat dissipation area of ​​the lamp base plate 2 and prevent the lamp base plate 2 from easily accumulating heat during the operation of the LED lamp panel 9. A through hole 73 is opened in the middle of the lamp base plate 2. The through hole 73 matches the central heat conduction pipe 71. The through hole 73 facilitates the insertion of the central heat conduction pipe 71 into the lamp base plate 2. A sealing ring 74 is embedded on the upper surface of the through hole 73. The sealing ring 74 is made of water-swellable rubber. The sealing ring 74 made of water-swellable rubber provides better sealing between the through hole 73 and the central heat conduction pipe 71, preventing external dust or rainwater from entering the transparent lamp cover 3 through the gap between the through hole 73 and the central heat conduction pipe 71 and causing the LED lamp panel 9 to be contaminated.

[0032] Example 2:

[0033] Based on Embodiment 1, in this embodiment, the LED lantern can be supported by installing the mounting bracket 85 and the connecting side plate 81. By loosening the locking nut 84, the connecting side plate 81 can be moved up and down, and the top plate 4 will move synchronously with the connecting side plate 81, thus making it convenient for installers to adjust the height of the LED lantern during installation.

[0034] The mounting components include a connecting side plate 81, a limiting notch 82, an external thread extension head 83, a locking nut 84, and a mounting bracket 85. The connecting side plate 81 is symmetrically fixed to the front and rear sides of the upper end of the lamp top plate 4. The connecting side plate 81 and the lamp top plate 4 are an integral structure. The connecting side plate 81 facilitates the connection of the mounting bracket 85 to the lamp top plate 4. The mounting bracket 85 is installed on the inner wall of the connecting side plate 81. The mounting bracket 85 is concave in shape and can support the connecting side plate 81. The side of the mounting bracket 85 is provided with an external thread extension head 83. The external thread extension head 83 is connected to the mounting bracket 85 by welding. The annular side of the external thread extension head 83 is equipped with a locking nut 84. The external thread extension head 83 and the locking nut 84 can install the mounting bracket 85 on the inner wall of the connecting side plate 81.

[0035] A limiting notch 82 is provided at the upper end of the connecting side plate 81. The limiting notch 82 matches the external thread extension head 83. The limiting notch 82 can not only limit the external thread extension head 83, but also allow the external thread extension head 83 to move up and down inside the connecting side plate 81, so that the installer can make fine adjustments to the installation height of the connecting side plate 81. The annular side of the external thread extension head 83 is fitted with an anti-loosening washer 87. The inner wall of the connecting side plate 81 is provided with anti-slip texture. The anti-loosening washer 87 makes the locking nut 84 more secure, and the anti-slip texture also makes the inner wall of the connecting side plate 81 more slip-resistant, thereby preventing the mounting bracket 85 from easily loosening and slipping off the connecting side plate 81 during use. The top of the mounting bracket 85 is provided with a mounting cavity 86. The mounting cavity 86 makes it convenient for the installer to install and fix the mounting bracket 85 to the lower end face of the extension plate 5 with external mounting bolts.

[0036] Working principle: During the use of LED lanterns, the central heat pipe 71, located in the middle of the lamp top plate 4, can absorb and conduct most of the heat in the middle area of ​​the transparent lampshade 3. At the same time, multiple heat-absorbing sheets 72, which are fixedly connected to the annular side of the central heat pipe 71, can further increase the heat absorption and conduction area of ​​the central heat pipe 71. The hollow structure of the central heat pipe 71 can also allow external air or rainwater to pass through the interior for cooling and heat dissipation. Moreover, the lamp top plate 4 and lamp bottom plate 2, which are made of aluminum-silicon alloy, have good thermal conductivity and can conduct most of the heat at the top and bottom ends of the transparent lampshade 3 and dissipate it to the outside. At the same time, multiple bottom heat sinks 75, which are fixedly connected, can further increase the heat dissipation area of ​​the lamp bottom plate 2, thereby preventing heat from easily accumulating inside the transparent lampshade 3.

[0037] By installing a hanger 85 on the lower end face of the extension plate 5, the hanger 85 can support the connecting side plate 81 through the external threaded extension head 83 and the locking nut 84, so that the connecting side plate 81 can support the lamp top plate 4. When it is necessary to make a fine adjustment to the height of the lamp top plate 4, the installer only needs to use an external wrench to loosen the locking nuts 84 on the front and rear sides respectively, and then the connecting side plate 81 can be moved up and down. The lamp top plate 4 will move synchronously with the connecting side plate 81, so that the installer can easily adjust the height of the LED lantern. After the adjustment is completed, the locking nut 84 can be tightened.

[0038] 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.
