Description
Technical Field
[0001] This utility model relates to the field of straight tube lamp technology, specifically to a straight tube lamp that facilitates heat dissipation. Background Technology
[0002] Straight tube lights, also known as LED fluorescent lights, are a replacement for traditional fluorescent tubes, primarily in terms of energy saving and environmental protection. Their size and installation method are the same as traditional fluorescent lamps, but they emit light using LED semiconductor chips. Common straight tube lights are classified into two categories based on their casing material: glass and aluminum / PC. Because straight tube lights save over 80% more energy than incandescent bulbs and have a lifespan more than 10 times that of ordinary tubes, they are widely used in the market. Currently, the LED chips in straight tube lights generate heat during use, requiring heat sinks to dissipate it promptly to ensure normal operation. However, existing straight tube lights typically dissipate heat by attaching heat sinks to the back of a metal substrate. These attached heat sinks are prone to detaching during prolonged use, affecting the normal heat dissipation of the straight tube light. Utility Model Content

[0017] Reference Figures 1 to 4 As shown, this utility model provides a straight tube lamp that facilitates heat dissipation, including: a heat dissipation shell 3, a main heat dissipation plate 2 symmetrically connected to the middle of the upper surface of the heat dissipation shell 3, and auxiliary heat dissipation plates 18 symmetrically connected to both sides of the upper surface of the heat dissipation shell 3, and a left end cover 4 and a right end cover 11 respectively fixedly connected to the two ends of the lower surface of the heat dissipation shell 3, with heat dissipation pipes 15 symmetrically connected between the left end cover 4 and the right end cover 11, and the branch pipes of the heat dissipation pipes 15 fixedly connected to the corresponding through holes opened in the heat dissipation shell 3, while the inner surface of the left end cover 4 is fixedly connected to the lamp tube 6 through the socket 5, and the outer surface of the right end cover 11 is fixedly connected to the fixing frame 13, with the main screw rod 12 movably connected to the fixing frame 13 through the bearing, and the positioning post 10 is slidably connected to the through opening opened in the right end cover 11 through the screwed main screw rod 12, the positioning post 10 is fixedly connected to the positioning plate 8 through the moving block 9, and the lower surface of the heat dissipation shell 3 is fixedly connected to the protective plate 7 through the fitting plate 14.
[0018] In this embodiment, the straight tube light is installed in a suitable position using the mounting plate 1. When the tube 6 is lit, the heat generated around the tube 6 is transferred to the heat sink 3, the heat sink 15, and the main heat sink 2. The heat in the heat sink 15 can heat the internal air, and the heated air will flow vertically upward through the branch pipe. At this time, the air pressure inside the main pipe of the heat sink 15 will be lower than the ambient air pressure, and then the ambient air can flow in through the openings at both ends of the main pipe, so that the air inside the heat sink 15 and around the straight tube light can be in a corresponding flow state, thereby helping to enhance the heat dissipation effect of the straight tube light. Furthermore, the arrangement of the heat sink 15, the heat sink 3, the main heat sink 2, and the auxiliary heat sink 18 can effectively increase the actual heat dissipation area on the outer side of the straight tube light, thereby helping to enhance the heat dissipation effect of the straight tube light.
[0019] As a preferred embodiment, the end face of the heat sink 3 is an isosceles trapezoidal structure. The two sets of interlocking plates 14 symmetrically connected on both sides of the lower surface of the heat sink 3 are both elongated structures. The surfaces on both sides of the interlocking plates 14 are fixedly connected with fastening layers, which are semi-cylindrical structures. At the same time, the end face formed by the combination of the interlocking plates 14 and the fastening layers is a cross-shaped structure.
[0020] In this embodiment, as Figure 2 and Figure 4The fastening layer is made of silicone, which helps to increase the frictional resistance at the connection between the interlocking plate 14 and the protective plate 7, thereby helping to enhance the stability of the connection between the heat sink 3 and the protective plate 7.
[0021] In a preferred embodiment, two sets of mounting plates 1 are symmetrically connected to both ends of the upper surface of the heat sink 3. Both sets of mounting plates 1 are U-shaped structures. Two sets of auxiliary heat sinks 18 are fixedly connected to the inclined surfaces on both sides of the upper surface of the heat sink 3. At the same time, the four sets of auxiliary heat sinks 18 are all semi-cylindrical structures, and the length of the auxiliary heat sinks 18 is equal to the length of the heat sink 3.
[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structure of the mounting plate 1 can reduce the degree of interference with airflow, thereby helping to enhance the effect of airflow on the surface of the heat sink 3 and the main heat sink 2. At the same time, the setting of the auxiliary heat sink 18 can help increase the heat dissipation area of the outer surface of the heat sink 3, thereby helping to enhance the heat dissipation effect of the outer surface of the straight tube lamp.
[0023] In a preferred embodiment, there are three sets of main heat sinks 2. All three sets of main heat sinks 2 have an E-shaped structure. The main heat sink 2 consists of a fixing part and an interlocking part. The fixing part has a long strip-shaped structure. Multiple sets of fixing parts are fixedly connected at equal intervals along the length direction on the lower surface of the fixing part. The fixing part has a rectangular structure.
[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structure of the main heat sink 2 can not only help increase the heat dissipation area of the outer side of the heat sink shell 3, but also help reduce the interference with airflow, ensuring that the airflow can flow in multiple directions, thereby helping to enhance the overall heat dissipation effect of the straight tube lamp.
[0025] In a preferred embodiment, a fixing groove is provided on the upper surface of the heat sink 3 relative to the position of the fixing part, and the protective plate 7 fixedly connected to the lower surface of the heat sink 3 by the interlocking plate 14 has a rectangular structure. The end face of the protective plate 7 has a U-shaped structure, and the corner of the protective plate 7 has an arc-shaped structure. At the same time, the surface of the protective plate 7 is respectively attached to the lower surface of the left end cover 4 and the right end cover 11.
[0026] In this embodiment, as Figure 1 and Figure 2The dimensions of the fixing groove and the fixing part are matched, which helps to enhance the stability of the connection between the main heat sink 2 and the heat sink shell 3. The protective plate 7 is made of transparent material, which can ensure the good lighting effect of the lamp tube 6. At the same time, the inner side of the protective plate 7 is matched with the dimensions of the left end cover 4 and the right end cover 11 respectively, which can help reduce the chance of mosquitoes or dust adhering around the lamp tube 6.
[0027] In a preferred embodiment, the heat dissipation pipe 15 has an overall E-shaped structure. The two ends of the heat dissipation pipe 15 are symmetrically connected to the heat insulation cylinder 16, and the heat insulation cylinder 16 has a cylindrical structure. The heat dissipation pipe 15 consists of branch pipes and main pipes. Multiple sets of branch pipes are fixedly connected to the upper surface of the main pipe at equal intervals along the length direction. The upper ends of the multiple sets of branch pipes are all fixedly connected to the filter plate 17 by snap-fit.
[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The heat insulation cylinder 16 effectively reduces the rate of temperature accumulation at both ends of the heat dissipation pipe 15, thereby creating a temperature difference between the two ends and the middle of the heat dissipation pipe 15. This facilitates the flow of external airflow from the openings at both ends of the main heat dissipation pipe 15, while the heated airflow can flow out from the branch pipe in the middle of the heat dissipation pipe 15, thus achieving airflow and enhancing the overall heat dissipation effect of the straight tube lamp. At the same time, corresponding filter structures are provided at the openings of the heat dissipation pipe 15 to reduce the chance of dust falling into it.
[0029] In a preferred embodiment, the fixing frame 13 fixedly connected to the surface of the right end cover 11 has a U-shaped structure, while the positioning post 10 screwed to the main screw 12 has a cuboid structure. The through opening on the surface of the right end cover 11 is adapted to the size of the positioning post 10. The moving block 9 fixedly connected to the positioning post 10 has a rectangular structure. Two sets of positioning plates 8 are symmetrically connected to the two ends of the moving block 9 near the lamp tube 6. Both sets of positioning plates 8 have a rectangular structure, and the end face of the positioning plate 8 has a fan-shaped annular structure.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The through-hole and the size of the positioning post 10 are matched to ensure that the main screw 12 can smoothly push the positioning post 10 to move horizontally, and prevent the positioning post 10 from rotating synchronously with the main screw 12. In addition, the arc surface of the inner side of the positioning plate 8 is matched with the arc of the outer side of the lamp tube 6, which can help enhance the support effect of the positioning plate 8 on the suspended end of the lamp tube 6, thereby helping to enhance the stability of the lamp tube 6 after installation inside the straight tube lamp.
