Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a strip light that facilitates heat dissipation. Background Technology

[0002] A strip light is a lighting fixture consisting of an LED light source, a control device, a light distribution component, and a housing. Its LED light source consists of one or two rows of LEDs, and its effective light-emitting length is much greater than its effective light-emitting width. It is used to replace traditional lighting fixtures such as fluorescent tubes and neon lights.

[0003] Chinese patent CN222616853U discloses an ultra-thin LED strip light design, belonging to the field of lighting technology. Its key technical features include a housing and a U-shaped heat-conducting plate. The front side of the U-shaped heat-conducting plate penetrates the rear side of the housing and extends into the interior. An LED light panel is installed inside the housing. The design comprises a housing, a U-shaped heat-conducting plate, an LED light panel, a transparent sealing plate, a U-shaped mounting plate, and a heat dissipation mechanism. The U-shaped heat-conducting plate is positioned at the top and bottom of the lamp housing, with its rear side located at the rear of the housing. The LED light panel is then placed inside the housing, within the U-shaped heat-conducting plate. The transparent sealing plate is then adhered to the front of the housing to enclose the LED light panel. The entire unit can then be installed in a suitable indoor location using the U-shaped mounting plate at the rear of the housing. During use, power is supplied synchronously to the LED light panel and a low-power, silent fan.

[0004] However, the above technical solution only uses a low-power, silent fan to accelerate airflow for cooling. But if the strip lights are used in some special places, such as libraries, study rooms and museums, the noise generated by the low-power, silent fan will be more prominent in relatively quiet places, which can easily cause discomfort. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a strip light that facilitates heat dissipation.

[0006] The technical solution of this utility model is as follows: A strip light with convenient heat dissipation includes a strip light body, which is composed of a light source, a housing, and a base. The light source is connected to the housing, and the housing and the base are slidably connected. A heat dissipation component is connected to the strip light body. The heat dissipation component includes elastic members and deformable members. Multiple evenly distributed elastic members are connected to the base and the housing at both ends, respectively. Multiple deformable members are connected to the housing and are slidably connected to the housing. In the use state, the heat generated by the light source heats the deformable members, causing them to deform and push the housing away from the base, increasing the contact area between the strip light body and the air.

[0007] Preferably, the housing consists of a frame and a partition plate, with the partition plate connected to the frame to divide the frame into two identical receiving slots, and the heat dissipation component and the light source respectively installed in the two receiving slots.

[0008] Preferably, the frame consists of a fixed plate and a rotating plate. The fixed plate has two symmetrically arranged notches at one end near the base. The rotating plate is rotatably connected to the notches and has multiple heat dissipation fins connected to it.

[0009] Preferably, the base is connected to multiple push rods, which are slidably connected to the rotating plate.

[0010] Preferably, the heat dissipation assembly also includes multi-stage telescopic rods, the number of which corresponds to the elastic element, with both ends of the multi-stage telescopic rods connected to the base and the partition plate, respectively.

[0011] Preferably, the rotating plates are connected to a sealing gasket on the side that is far apart from each other.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] In this invention, the heat generated by the main body of the strip light during operation causes the shape-memory alloy deformable component to deform, the shell moves away from the base to increase the contact area with air, and at the same time the rotating plate moves out of the housing groove of the shell to contact the outside air to increase the contact area, thereby enhancing the heat dissipation capacity. When the main body of the strip light works for a short time, it can maintain heat dissipation through its own material, and the heat dissipation fins are stored in the housing groove to prevent external dust from adhering and affecting its performance.

[0019] Example 1

[0020] like Figures 1-4 As shown, this utility model proposes a strip light with convenient heat dissipation, including a strip light body 1 and a heat dissipation assembly. The strip light body 1 consists of a light source 2, a housing 3, and a base 4. The light source 2 is connected to the housing 3, and the housing 3 is slidably connected to the base 4. The heat dissipation assembly is connected to the strip light body 1 and includes elastic elements 5 and deformable elements 6. Multiple evenly distributed elastic elements 5 are connected at both ends to the base 4 and the housing 3, respectively, and multiple deformable elements 6 are connected to the housing 3. The deformable elements 6 are made of shape memory alloy, which takes on an inverted V-shape after unfolding. The deformable elements 6 are slidably connected to the housing 3. In the use state, the heat generated by the light source 2 heats the deformable elements 6, causing them to deform and push the housing 3 away from the base 4, increasing the contact area between the strip light body 1 and the air.

[0021] Example 2

[0022] like Figures 2-4 As shown, this utility model proposes a strip light that facilitates heat dissipation. Compared with Embodiment 1, this embodiment describes the detailed structure of the housing 3. The housing 3 is composed of a frame 7 and a partition plate 8. The partition plate 8 is connected to the frame 7 and divides the frame 7 into two identical receiving slots. The heat dissipation component and the light source 2 are respectively installed in the two receiving slots.

[0023] In an optional embodiment, the frame 7 is composed of a fixed plate 9 and a rotating plate 10. The fixed plate 9 has two symmetrically arranged notches at one end near the base 4. The rotating plate 10 is rotatably connected to the notches, and multiple heat dissipation fins 11 are connected to the rotating plate 10.

[0024] In an optional embodiment, a plurality of push rods 12 are connected to the base 4, and the push rods 12 are slidably connected to the rotating plate 10.

[0025] Example 3

[0026] like Figures 2-3 As shown, this utility model proposes a strip light that facilitates heat dissipation. Compared with Embodiment 2, this embodiment describes the detailed structure of the heat dissipation component. The heat dissipation component also includes multi-stage telescopic rods 13. The number of multi-stage telescopic rods 13 corresponds to the number of elastic elements 5. The two ends of the multi-stage telescopic rods 13 are respectively connected to the base 4 and the partition plate 8. The multi-stage telescopic rods 13 are guided and limited by the distance between the base 4 and the housing 3.

[0027] In an optional embodiment, a sealing gasket 14 is connected to the side of the rotating plate 10 that is away from each other; the sealing gasket 14 is made of, but is not limited to, rubber and silicone, and is used to block the gap between the fixed plate 9 and the rotating plate 10 to prevent dust from entering.

[0028] In summary, when this utility model is used, the strip light body 1 is installed on the ceiling with bolts. When the strip light body 1 is turned on, the light source 2 produces light to provide illumination. While the light source 2 is illuminating, it continuously generates heat. This heat is dissipated outward from the aluminum alloy shell 3 through contact with the shell 3. If the heat dissipation rate is not fast enough, causing the temperature of the shell 3 to gradually rise to the temperature that triggers the deformation of the deformable part 6, the shape memory alloy deformable part 6 will deform. After deformation, the deformable part 6 can resist the elasticity of the elastic part 5 and push the shell 3 away from the base 4. The shell 3 gradually moves away from the base 4, allowing it to come into contact with the air. With the increase in contact area, the rotating plate 10 will also rotate on its own due to the removal of the constraint of the push rod 12. The rotating plate 10 changes from a vertical loading state to a horizontal state. The heat dissipation fins 11 on the rotating plate 10 expand outward to increase the contact area between the shell 3 and the outside air, thereby enhancing the heat dissipation effect. It also avoids the problem of dust accumulation caused by long-term contact between the heat dissipation fins 11 and the outside air, which affects heat dissipation. After the temperature of the shell 3 gradually decreases, the deformable part 6 gradually cools down. At this time, the elastic part 5 rebounds and moves the shell 3 closer to the base 4, and compresses the deformable part 6 through the change of the distance between the two, waiting for the next operation.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
