Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and in particular relates to a rigid light strip with double-sided LED beads. Background Technology

[0002] LED light strips are widely used in various scenarios such as home decoration, commercial display, and advertising signage due to their advantages such as energy saving, long life and small size. However, traditional rigid light strips usually only have LED beads on one side, which has many limitations in practical applications.

[0003] For example, a single-sided LED rigid light strip cannot illuminate all angles, creating shadows and affecting the display and visual effect. Furthermore, its lighting efficiency is low. To achieve sufficient brightness, the number of light strips needs to be increased or higher-power LEDs need to be used. This not only increases costs but also causes heat dissipation problems. Existing LED rigid light strips are usually actively cooled. When there is too much heat, it will accumulate inside the light strip. Prolonged heat accumulation will not only shorten the lifespan of the LEDs and reduce the stability of the lighting equipment, but may also cause safety hazards, such as the risk of fire due to overheating.

[0004] To address this issue, we provide a rigid LED strip with double-sided LED beads to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a rigid LED strip with double-sided LED beads. The heat from the two LED strips is conducted to the heat sink through a silicone grease layer, and then the hot air inside the heat sink is discharged by a fan. This solves the problems of small light-emitting area and poor heat dissipation of existing rigid LED strips.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a rigid light strip with double-sided LED beads, including a heat sink, two LED light strips and two connecting tubes; the two LED light strips are fixedly connected to the front and back sides of the heat sink respectively, the two connecting tubes are installed at both ends of the heat sink, and an air inlet pipe and an air outlet pipe are respectively installed at the bottom of the two connecting tubes, and a fan is installed at the free end of the air inlet pipe.

[0008] The present invention is further configured such that mounting grooves are provided on both sides of the heat sink, and the two LED strips are respectively fixedly connected to the inside of the two mounting grooves by screws, and a layer of silicone grease is evenly applied between the LED strips and the heat sink.

[0009] The present invention is further configured such that a plurality of heat dissipation fins are fixedly connected inside the heat dissipation pipe and arranged horizontally from top to bottom.

[0010] The present invention is further configured such that the connecting pipe includes a fixed pipe, the lower outer end of the fixed pipe is provided with an external thread, the top of the fixed pipe is movably sleeved with a movable pipe, and the top of the inner cavity of the movable pipe is provided with an internal thread that is compatible with the fixed pipe.

[0011] The present invention is further configured such that a retaining ring is fixedly connected inside the movable tube, a sealing plug is threaded onto the top of the movable tube, and a second sealing ring is fixedly connected to the bottom of the sealing plug.

[0012] The present invention is further configured such that a first sealing ring is fixedly connected to the lower end of the inner side of the movable tube, and the first sealing ring is in contact with the outer wall of the fixed tube.

[0013] The present invention is further provided that a mounting plate is fixedly connected to the bottom of the heat dissipation pipe, and a plurality of mounting holes are evenly opened in the horizontal direction inside the mounting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. The heat emitted by the two LED light strips of this utility model is conducted to the surface of the heat sink through the silicone grease layer. Then, the heat is conducted to the inside of the heat sink through multiple heat sink fins, which heats the air inside the heat sink. Subsequently, the fan is started to introduce high-speed airflow into the heat sink through the air inlet pipe, so that the hot air inside the heat sink can be discharged along the air outlet pipe. This can remove the heat generated by the two LED light strips, greatly improve the heat dissipation efficiency of the two LED light strips, and extend the service life of the LED beads.

[0016] 2. This utility model allows for the adjustment of the spacing between adjacent LED light strips by pulling the movable tube. After adjustment, the movable tube is screwed into the bottom of the adjacent fixed tube, thus connecting the adjacent connecting tubes.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1 to 4 This utility model relates to a rigid LED strip with double-sided LED beads, comprising a heat sink 100, two LED strips 200, and two connecting pipes 300. The two LED strips 200 are fixedly connected to the front and back sides of the heat sink 100, and the two connecting pipes 300 are installed at both ends of the heat sink 100. An air inlet pipe 400 and an air outlet pipe 600 are respectively installed at the bottom of the two connecting pipes 300. A fan 700 is installed at the free end of the air inlet pipe 400. The double-sided LED strip design increases the light-emitting area, resulting in a wider and more uniform illumination range. The air injected into the heat sink 100 by the fan 700 can remove the heat generated by the two LED strips 200, thereby greatly improving the heat dissipation efficiency of the two LED strips 200 and extending the service life of the LED beads.

[0029] Specifically, mounting grooves 102 are provided on both sides of the heat sink 100, and the two LED strips 200 are fixedly connected to the inside of the two mounting grooves 102 by screws. A layer of silicone grease 103 is evenly applied between the LED strips 200 and the heat sink 100. The mounting grooves 102 can ensure the stability of the LED strips 200 installation, so that they will not shift due to vibration, collision or other factors during long-term use. The applied silicone grease layer 103 can further enhance the heat transfer efficiency between the two, so that the heat generated by the LED strips 200 can be conducted to the heat sink 100 more quickly and efficiently, thereby effectively improving the overall heat dissipation performance.

[0030] Furthermore, the heat pipe 100 has multiple heat dissipation fins 101 arranged horizontally from top to bottom inside. The heat dissipation fins 101 can increase the heat dissipation area, thereby further improving the overall heat dissipation performance.

[0031] The operation process of this embodiment is as follows: When it is necessary to dissipate heat from the two LED light strips 200, the heat emitted by the two LED light strips 200 is first conducted to the surface of the heat sink 100 through the silicone grease layer 103. Then, the heat is conducted to the interior of the heat sink 100 through multiple heat dissipation fins 101, which heats the air inside the heat sink 100. Subsequently, the fan 700 is started to introduce high-speed airflow into the interior of the heat sink 100 through the air inlet pipe 400, so that the hot air inside the heat sink 100 can be discharged along the air outlet pipe 600, thereby removing the heat generated by the two LED light strips 200, greatly improving the heat dissipation efficiency of the two LED light strips 200 and extending the service life of the LED beads.

[0034] Specifically, a retaining ring 302a is fixedly connected inside the movable tube 302, a sealing plug 303 is threaded onto the top of the movable tube 302, and a second sealing ring 303a is fixedly connected to the bottom of the sealing plug 303. The top of the movable tube 302 can be sealed by the sealing plug 303, and the sealing performance can be improved by the second sealing ring 303a.

[0035] Furthermore, a first sealing ring 302b is fixedly connected to the lower inner end of the movable tube 302, and the first sealing ring 302b is in contact with the outer wall of the fixed tube 301.

[0036] A mounting plate 500 is fixedly connected to the bottom of the heat dissipation pipe 100. Multiple mounting holes are evenly opened in the horizontal direction inside the mounting plate 500. The mounting plate 500 makes it easier to install the utility model.

[0037] The operation process of this embodiment is as follows: First, by pulling the movable tube 302, the spacing between adjacent LED light strips 200 can be adjusted. After the adjustment is completed, the movable tube 302 is screwed into the bottom of the adjacent fixed tube 301, so that the adjacent connecting tubes 300 can be connected.
