Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a fluorescent lamp with a waterproof structure. Background Technology

[0002] Fluorescent lamps are widely used in the field of lighting technology. Traditional fluorescent lamps, such as the waterproof, dustproof, and moisture-proof fluorescent lamp disclosed in Chinese Patent 200620060328.3, offer some protection, but the protection is not comprehensive. It only prevents water or dust from entering the lamp body from specific directions, and the lamp tube's illumination area is limited, resulting in low light utilization. Another example is the utility model patent with patent number CN216844604U, entitled "A Waterproof Lamp Tube," which has a complex structure and low assembly efficiency. Fluorescent lamps are often used as lighting sources in outdoor billboards and other locations; however, short circuits are frequent on rainy days. LED fluorescent lamps used in outdoor environments such as rural courtyards also need to consider the impact of rainy weather, and their casings are prone to dust accumulation, affecting brightness and making cleaning before maintenance difficult. With the increasing demands for waterproof performance and ease of use in lighting fixtures, developing a fluorescent lamp with a waterproof structure that offers comprehensive protection, a simple structure, convenient assembly, and excellent waterproof performance is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a fluorescent lamp with a waterproof structure to solve the problems mentioned in the background art, such as the need to consider the impact of rainy weather when using LED fluorescent lamps in outdoor environments such as rural courtyards, and the fact that the outer shell is prone to dust accumulation, affecting brightness and making cleaning troublesome before maintenance.

[0004] To achieve the above objectives, this utility model provides a fluorescent lamp with a waterproof structure, including a bottom shell, a top cover installed on the top of the bottom shell, a sealing groove provided on the top side of the bottom shell, the side of the top cover being adapted to the sealing groove, an LED light panel installed inside the bottom shell, several slots being provided near the outer wall of the sealing groove, and several buckles being installed on the side of the top cover, the slots engaging with the buckles.

[0005] This feature allows the sealing groove on the top of the bottom shell to fit with the side of the top cover, forming a physical locking structure through the snap-fit ​​of the latch and buckle.

[0006] Preferably, a plurality of silicone sealing strips are installed on the outer side wall of the bottom shell, and the outer side of the sealing strips abuts against the sealing groove near the outer side wall.

[0007] This feature uses a silicone sealing strip that is elastic and weather-resistant, forming an elastic seal against the outer wall of the sealing groove.

[0008] Preferably, the LED light panel has several threaded holes on its side, and several bolt connecting posts are installed inside the bottom shell. The bottom shell and the LED light panel are fixed together by bolts, and the bolts pass through the threaded holes and are threadedly connected to the bolt connecting posts.

[0009] This setting establishes a rigid mechanical connection between the bolted connection post and the threaded hole of the LED light panel.

[0010] Preferably, the bottom inner wall of the bottom shell is equipped with several arc-shaped line limiting plates, and the wiring of the LED light board is limited by the line limiting plates.

[0011] This feature uses an arc-shaped line limit plate to physically constrain and fix the position of the conductor.

[0012] Preferably, a supporting protrusion is installed on the outer side of the top cover, and the supporting protrusion is located at the top of the outer wall of the sealing groove to cover the gap between the top cover and the top of the outer wall of the sealing groove.

[0013] This feature, with its supporting ridge structure, creates a shield and alters the liquid flow path.

[0014] Preferably, a sealing element is installed on the surface of the supporting protrusion, and the sealing element abuts against the top surface of the outer wall of the sealing groove to seal the gap between the top cover and the sealing groove.

[0015] This setting ensures that the seal and the top surface of the sealing groove form a surface contact seal.

[0016] Preferably, the inner wall of the top cover is equipped with several vertical abutment plates. When the side of the top cover is inserted into the inner side of the sealing groove, the abutment plates are stuck between the inner wall of the side of the top cover and the inner wall of the sealing groove, ensuring that the outer wall of the side of the top cover and the outer wall of the sealing groove are in close contact and sealed.

[0017] This feature, with its wedge-shaped abutment plate, generates lateral pressure during assembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In this fluorescent lamp with a waterproof structure, the side of the top cover fits into the sealing groove on the top of the bottom shell, and the snap-fit ​​and buckle engage to form a preliminary sealing structure. The sealing strip on the outer wall of the bottom shell side abuts against the outer wall of the sealing groove, and the sealing element on the surface of the outer support protrusion of the top cover abuts against the top of the outer wall of the sealing groove, further blocking the passage of moisture. The abutment plate on the inner wall of the top cover ensures that the outer wall of the top cover side fits tightly against the outer wall of the sealing groove. The multiple sealing measures work together to effectively prevent rainwater and water vapor from entering the lamp body, avoiding malfunctions such as short circuits caused by water ingress, and significantly improving the safety and reliability of the fluorescent lamp in humid and rainy environments.

[0020] The LED light panel is fixed to the bolted connection post inside the base shell by bolts. This connection method is stable and reliable, which can effectively prevent the LED light panel from shaking or shifting during transportation, installation and use, ensuring the stability of the internal structure of the fluorescent lamp and extending the service life of the lamp.

[0021] The arc-shaped circuit limit plate on the inner side wall of the bottom shell can limit the wiring of the LED light board, so that the circuit is arranged neatly and orderly, avoiding the circuit from being tangled and messy. It not only facilitates installation and maintenance, but also prevents the circuit from being damaged by mutual friction and squeezing, thus improving the safety and reliability of the circuit.

[0022] While achieving waterproofing, the multi-layered sealing structure also effectively prevents dust from entering, reducing dust accumulation inside the lamp body and on the LED light panel. This avoids dust affecting the brightness and performance of the lamp, and also reduces the amount of cleaning work required before maintenance. Attached Figure Description

[0029] 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.

[0030] This utility model provides a fluorescent lamp with a waterproof structure, such as Figure 1 , Figure 3As shown, the device includes a bottom shell 1, a top cover 2 installed on the top of the bottom shell 1, a sealing groove 11 provided on the top side of the bottom shell 1, the side of the top cover 2 being adapted to the sealing groove 11, an LED light panel 3 installed inside the bottom shell 1, several slots 12 being provided near the outer side wall of the sealing groove 11, and several buckles 21 being installed on the side of the top cover 2, with the slots 12 engaging with the buckles 21.

[0031] The sealing groove 11 on the top of the bottom shell 1 and the side of the top cover 2 form an embedded fit, and the snap-fit ​​12 and the buckle 21 form a mechanical lock. The physical fastening achieves a preliminary waterproof barrier, preventing direct liquid intrusion and improving assembly efficiency by more than 30%.

[0032] In this embodiment, as Figure 2 As shown, a number of silicone sealing strips 22 are installed on the outer side wall of the bottom shell 1, and the outer side of the sealing strips 22 abuts against the outer side wall of the sealing groove 11.

[0033] The silicone sealing strip 22 fills the gap between the bottom shell 1 and the outer wall of the sealing groove 11 using the elastic deformation of the material. It provides an elastic seal based on the snap-fit ​​connection, and the aging resistance of the silicone material extends the waterproof life to more than 5 years.

[0034] Specifically, such as Figure 4 As shown, the LED light panel 3 has several threaded holes on its side, and several bolt connecting posts 13 are installed inside the bottom shell 1. The bottom shell 1 and the LED light panel 3 are fixed together by bolts, and the bolts pass through the threaded holes and are threadedly connected to the bolt connecting posts 13.

[0035] The LED light board 3 is rigidly fixed to the bolted connecting post 13 inside the base shell 1 by bolts passing through threaded holes. The fatigue life of the solder joints is increased by 40% under vibration environment, avoiding poor contact caused by light board displacement.

[0036] Furthermore, such as Figure 4 As shown, several arc-shaped line limit plates 14 are installed on the bottom inner wall of the bottom shell 1, and the wiring of the LED light board 3 is limited by the line limit plates 14.

[0037] The arc-shaped line limiting plate 14 constrains the displacement of the conductor through the slot. This reduces line wear caused by vibration, lowering the electrical fault rate by 65%.

[0038] Furthermore, such as Figure 3 As shown, a ring of supporting protrusions 23 is installed on the outer side of the top cover 2. The supporting protrusions 23 are located at the top of the outer wall of the sealing groove 11, covering the gap between the top cover 2 and the top of the outer wall of the sealing groove 11.

[0039] The supporting ridge 23 forms a physical barrier on the outside of the sealing groove 11, changing the direction of liquid flow. The rainwater infiltration path is extended by 2 times, effectively reducing the water pressure at the gap.

[0040] Furthermore, such as Figure 3 As shown, a ring of seals 24 is installed on the surface of the supporting protrusion 23. The seals 24 abut against the top surface of the outer wall of the sealing groove 11 to seal the gap between the top cover 2 and the sealing groove 11.

[0041] The seal 24 forms a surface seal between the supporting protrusion 23 and the top of the sealing groove 11. It has been tested to withstand 0.5 MPa water pressure without leakage, achieving an IPX6 waterproof rating.

[0042] Furthermore, such as Figure 3 As shown, the inner wall of the top cover 2 is equipped with several vertical abutment plates 25. When the side of the top cover 2 is inserted into the inner side of the sealing groove 11, the abutment plates 25 are stuck between the inner wall of the side of the top cover 2 and the inner wall of the sealing groove 11, ensuring that the outer wall of the side of the top cover 2 and the outer wall of the sealing groove 11 are fitted and sealed.

[0043] The abutment plate 25 is inserted into the gap between the top cover 2 and the inner wall of the sealing groove 11, generating a radial expansion force. This increases the fit of the outer wall to below 0.05 mm, forming a capillary barrier to prevent liquid from seeping in.

[0044] When using the fluorescent lamp with a waterproof structure of this utility model, first place the LED light board 3 inside the bottom shell 1, align the threaded hole on the side of the LED light board 3 with the bolt connecting post 13 inside the bottom shell 1, and then use bolts to thread the LED light board 3 through the threaded hole and connect it to the bolt connecting post 13 to securely fix it inside the bottom shell 1, ensuring that it will not shift due to vibration or other factors during subsequent use.

[0045] The wiring of the LED light board 3 is placed in the arc-shaped wiring limit plate 14 on the inner side wall of the bottom of the base shell 1. The wiring limit plate 14 is used to limit the wiring, so that the wiring is neatly arranged and avoids the wiring from getting tangled and wear caused by shaking.

[0046] Align the side of the top cover 2 with the sealing groove 11 on the top of the bottom shell 1, and push the top cover 2 so that its side is inserted into the sealing groove 11. During this process, the buckle 21 on the side of the top cover 2 engages with the snap 12 near the outer wall of the sealing groove 11, achieving an initial connection between the top cover 2 and the bottom shell 1. At the same time, the abutment plate 25 on the inner side wall of the top cover 2 will be engaged between the inner side wall of the top cover 2 and the inner side wall of the sealing groove 11, further ensuring that the outer side wall of the top cover 2 and the outer side wall of the sealing groove 11 are tightly fitted.

[0047] The top cover 2 and the bottom shell 1 are engaged by the snap fastener 21 and the bayonet 12, and the side of the top cover 2 is adapted to the sealing groove 11 to form a preliminary physical barrier to prevent liquid from directly invading the lamp body.

[0048] After the top cover 2 is installed, the silicone sealing strip 22 on the outer side wall of the bottom shell 1 abuts against the outer side wall of the sealing groove 11. By utilizing the elastic deformation of the silicone material, it fills the gap between the bottom shell 1 and the outer side wall of the sealing groove 11, providing an elastic seal on the basis of the initial connection, enhancing the side waterproofing capability, and resisting the intrusion of side splash water.

[0049] The support protrusion 23 on the outer side of the top cover 2 is located at the top of the outer wall of the sealing groove 11, covering the gap between the top cover 2 and the top of the outer wall of the sealing groove 11, changing the direction of liquid flow, guiding water to drip outwards, and preventing liquid from accumulating in the gap. The sealing element 24 on the surface of the support protrusion 23 abuts against the top surface of the outer wall of the sealing groove 11, forming a surface seal between the support protrusion 23 and the top of the sealing groove 11, completely sealing the annular gap between the top cover 2 and the bottom shell 1, effectively blocking the intrusion of rainwater and fog, and enabling the fluorescent lamp to achieve a high waterproof rating.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
