Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to an outdoor waterproof LED T8 tube. Background Technology

[0002] T8 fluorescent tubes are a new type of LED light that are becoming increasingly widely used in daily life. They are a popular choice for green, environmentally friendly, and energy-saving light tubes, offering advantages such as energy saving, long lifespan, environmental friendliness, easy installation, and healthier light for the human body.

[0003] A search revealed that Chinese utility model patent CN202120072516.2 discloses a T8 explosion-proof lamp tube, including a diffuser cover. A light source plate is disposed inside the diffuser cover, and a heat sink is disposed at the bottom of the diffuser cover. An inward-folding anti-detachment groove is provided at the bottom of the diffuser cover, and an outward-folding anti-detachment buckle is provided at the top of the heat sink. The surface of the outward-folding anti-detachment buckle is fastened and fixed to the inward-folding anti-detachment groove. This invention, through the cooperation of the diffuser cover, light source plate, heat sink, inward-folding anti-detachment groove, outward-folding anti-detachment buckle, and end caps, and the inward-folding anti-detachment groove at the bottom of the diffuser cover and the outward-folding anti-detachment buckle at the top of the heat sink, prevents the diffuser cover from detaching from the heat sink, preventing damage to the lamp tube and improving its lifespan. Furthermore, the end caps on both sides are fastened to the diffuser cover, reducing the use of glue and making maintenance more time-saving and labor-saving, bringing great convenience to the user.

[0004] For example, Chinese utility model patent application CN202120350616.7 discloses a T8, T10, and T12 lamp tube with retractable plugs, including a first plug, a second plug, a third plug, a power supply, a flexible substrate assembly, and a glass lamp tube. The inner wall of the glass lamp tube is bonded with thermally conductive silicone, and the flexible substrate assembly is bonded to the inner wall of the thermally conductive silicone. Power supplies are fixedly connected to opposite ends of the glass lamp tube. Alignment points on the first plug are bonded to the lamp beads and the flexible substrate assembly with thermally conductive silicone, and these alignment points are aligned with the center of the lamp beads, the flexible substrate assembly, and the glass lamp tube. This type of retractable plug T8, T10, and T12 lamp tube has a novel design and simple structure. The lamp beads and the flexible substrate assembly are bonded to the inner wall of the glass lamp tube with thermally conductive silicone, which improves the heat dissipation of the lamp tube, ensuring its overall lifespan and meeting the needs of users. It also facilitates the locking of the second plug between the first and third plugs, ensuring that the second plug cannot rotate.

[0005] While existing lamp tubes can meet basic usage requirements, they achieve waterproofing by filling the gap between the plug and the plastic light-transmitting cover with sealant. However, the amount of sealant applied at the assembly points of the plug at the wire inlet end, the plug at the non-wire inlet end, and the plastic light-transmitting cover is large and costly. Furthermore, the sealant level inside the plug is high, and a small proportion of the sealing gap is not filled, resulting in poor waterproofing and a poor waterproofing effect. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an outdoor waterproof LED T8 light tube that addresses the above-mentioned deficiencies of the prior art. By setting an inner sealing part and an outer sealing part to clamp the end of the light tube body, a first layer of waterproof sealing is achieved. By setting a shrink film, the sealing between the first waterproof plug and the second waterproof plug and the light tube body is further improved, achieving a second layer of sealing, thereby enhancing the waterproof effect. The waterproof effect is good, and there is no need to fill with sealant, resulting in lower cost.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0008] An outdoor waterproof LED T8 tube is provided, wherein the ends of the tube body are respectively provided with a first waterproof plug, a second waterproof plug, and a shrink film.

[0015] Preferably, both the first arc-shaped connecting portion and the second arc-shaped connecting portion have an arc-shaped surface on their outer sides.

[0016] Preferably, the cable outlet hole includes a first cable outlet hole and a second cable outlet hole, both of which are circular.

[0017] Preferably, the cross-section of the cable outlet is circular, and the cross-sectional area of ​​the cable outlet decreases sequentially from the inside out.

[0018] By adopting the above technical solution, the present invention provides an outdoor waterproof LED T8 light tube with the following beneficial effects: The end of the light tube body of the outdoor waterproof LED T8 light tube is respectively provided with a first waterproof plug, a second waterproof plug, and a shrink film. The shrink film covers the outer side of the first waterproof plug and the second waterproof plug.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] like Figure 1-4As shown, the outdoor waterproof LED T8 tube includes a tube body 1. The ends of the tube body 1 are respectively provided with a first waterproof plug 2, a second waterproof plug 3, and a shrink film 4. The shrink film 4 covers the outside of the first waterproof plug 2 and the second waterproof plug 3. The first waterproof plug 2 includes a first inner sealing part 5, a first outer sealing part 6, and a first arc-shaped connecting part 7. The first arc-shaped connecting part 7 is integrally connected with the first inner sealing part 5 and the first outer sealing part 6. The second waterproof plug 3 includes a second inner sealing part 8, a second outer sealing part 9, and a second arc-shaped connecting part 10. The second arc-shaped connecting part 10 is integrally connected with the second inner sealing part 8 and the second outer sealing part 9. Understandably, the lamp body 1 includes a lampshade 25, an LED light strip 26, and a PCB circuit board 27, etc. The PCB circuit board 27 is electrically connected to the LED light strip 26 and is connected to an external power supply through a power cord. The lampshade 25 can be made of glass or light-transmitting plastic, etc. The first waterproof plug 2 and the second waterproof plug 3 can both be made of rubber or silicone, etc., which can better fit and protect the lampshade. The shrink film 4 can be a general shrinkable film, etc., which can cover the outside of the connection between the lamp body 1 and the plug, further improving the waterproof sealing.

[0028] Specifically, the outer side of the second arc-shaped connecting portion 10 is provided with a cable outlet portion 11, which has several cable outlet holes 12. These cable outlet holes 12 communicate with the inner side of the second sealing portion 11. Each cable outlet hole 12 includes a first cable outlet hole and a second cable outlet hole, both of which are circular. The cross-section of the cable outlet portion 11 is also circular, with the cross-sectional area decreasing sequentially from the inside out. It is understood that the cable outlet holes 12 are used to allow the power cord to pass through, and their inner side can tightly fit against the outer side of the power cord, thereby preventing moisture from entering.

[0029] Specifically, a first lampshade engaging groove 13 is provided between the first inner sealing part 5 and the first outer sealing part 6, and a second lampshade engaging groove 14 is provided between the second inner sealing part 8 and the second outer sealing part 9. Understandably, during installation, the end of the lampshade 25 is engaged into the first lampshade engaging groove 13 and the second lampshade engaging groove 14, thereby clamping the lampshade 25.

[0030] Specifically, the front end of the opening of the first lampshade locking groove 13 is sequentially provided with a first front outer support ring 15 and a first rear outer support ring 16, and the front end of the opening of the second lampshade locking groove 14 is sequentially provided with a second front outer support ring 17 and a second rear outer support ring 18; a first buffer groove 19 is provided between the first front outer support ring 15 and the first rear outer support ring 16, and a second buffer groove 20 is provided between the second front outer support ring 17 and the second rear outer support ring 18. It can be understood that through the mutual cooperation of the aforementioned front and rear outer support rings, the aforementioned inner sealing part can tightly press against the inner side of the lampshade 25, thus better fitting the lampshade 25.

[0031] Specifically, a first outwardly inclined surface 21 is provided between the end of the first inner sealing part 5 and the first front outer support ring 15, and a second outwardly inclined surface 22 is provided between the end of the second inner sealing part 6 and the second front outer support ring 17. It can be understood that by providing the first outwardly inclined surface 21 and the second outwardly inclined surface 22, the first waterproof plug 2 and the second waterproof plug 3 can be better inserted into the lamp cover 25 during assembly, improving assembly convenience.

[0032] Specifically, the outer diameter of the first front outer support ring 15 is equal to the outer diameter of the first rear outer support ring 16, and the outer diameter of the first front outer support ring 15 is smaller than the outer diameter of the first outer sealing part 6; the outer diameter of the second front outer support ring 17 is equal to the outer diameter of the second rear outer support ring 18, and the outer diameter of the second front outer support ring 17 is smaller than the outer diameter of the second outer sealing part 9. It can be understood that the aforementioned outer sealing part covers the outer side of the lamp cover 25, while the front and rear outer support rings abut against the inner side of the lamp cover 25. Their mutual cooperation allows for a better fit to the lamp cover 25, thereby improving sealing performance.

[0033] Specifically, both the first arc-shaped connecting portion 7 and the second arc-shaped connecting portion 10 have an arc-shaped surface 23 on their outer sides. It can be understood that the arc-shaped surface 23 allows the side of the waterproof plug to protrude outward, which can better protect the lampshade 25 and internal components from damage by impact.

[0034] Understandably, this invention is rationally designed and uniquely constructed. By setting an inner sealing part and an outer sealing part to cooperate with each other to clamp the end of the lamp tube body, the first waterproof plug 2 and the second waterproof plug 3 can better fit the end of the lamp tube body 1, thereby achieving the first layer of waterproof sealing. By setting a shrink film 4 to cover the end of the first waterproof plug 2 and the second waterproof plug 3 with the end of the lamp tube body 1, the sealing performance between the first waterproof plug 2 and the second waterproof plug 3 and the lamp tube body 1 is further improved, achieving the second layer of sealing, thereby improving the waterproof effect. The waterproof effect is good, avoiding the phenomenon of poor waterproofing, and there is no need to fill with sealant, which can greatly reduce production costs. Assembly and disassembly are also more convenient and the cost is lower.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
