Description

Technical Field

[0001] The utility model relates to a waterproof fluorescent lamp strip end cover, in particular to a fluorescent lamp end cover which realizes waterproof sealing through glass glue filling and structural fixation. Background Art

[0002] With the continuous development of lighting technology, fluorescent lamps have gradually become an indispensable part of home, office, and industrial lighting. Fluorescent lamps are characterized by high efficiency and energy saving. However, with the diversification of application environments, especially in harsh conditions such as humidity and dust, the waterproofing of fluorescent lamps has gradually become an important research topic.

[0003] In practical applications, the end caps of fluorescent lamps must not only provide good waterproof performance, but also have certain stability and shock resistance to ensure the safety and reliability of the lamps during use. In the existing technology, traditional fluorescent lamp end cap structures often use sealing rings or sealing tape to achieve waterproofing.

[0004] However, these traditional methods have the following problems:

[0005] First, the sealing ring is prone to aging after long-term use, resulting in a decrease in the sealing effect, making it impossible to guarantee long-term waterproofness. In addition, the adhesion of the sealing tape is greatly affected by environmental factors such as temperature and humidity, and it is prone to failure under extreme conditions.

[0006] Secondly, while existing waterproof structures meet basic waterproofing requirements, they often neglect the robustness of the joints. This is especially true when the luminaire is subjected to external forces or prolonged vibration. Traditional sealing structures can become loose, leading to a decrease in sealing effectiveness, which in turn affects the overall performance and lifespan of the luminaire. Furthermore, over long-term use, the sealing material may gradually lose its effectiveness due to environmental changes, further reducing its waterproofing effectiveness.

[0007] Finally, although some new waterproof end cap designs improve sealing performance by optimizing the structure, such as directly embedding sealing materials in the end caps, or adding fixing points to enhance the stability of the connection, these designs have improved the waterproof effect to a certain extent. However, the manufacturing process of these solutions is complex and costly, and in actual applications, the sealing effect is still difficult to maintain for a long time, especially in outdoor or high-humidity environments. Traditional waterproof solutions are difficult to meet the needs of long-term stability.

[0008] Therefore, there is still a need for a simpler, more economical and long-term stable waterproof end cap solution to improve the reliability and applicability of fluorescent lamps in diverse environments. Utility Model Content

[0030] like Figures 1 to 11 As shown, a waterproof fluorescent light strip end cap comprises a plastic end cap (10), a light strip (20) and a waterproof portion (30).

[0031] like Figures 1 to 2 As shown, the waterproof portion (30) is arranged in the plastic end cap (10), the plastic end cap (10) is connected to the end of the light bar (20), and the waterproof portion (30) is sealed between the plastic end cap (10) and the light bar (20).

[0032] During specific implementation, when the plastic end cap (10) is connected to the light bar (20), the waterproof portion (30) can completely seal the plastic end cap (10) and the light bar (20), thereby achieving a waterproof effect.

[0033] In practice, the waterproof portion (30) is glass glue.

[0034] Furthermore, an inner groove (11) is concavely provided inside the plastic end cover (10), and the inner groove (11) is arranged in a ring in the plastic end cover (10).

[0035] The waterproof portion (30) is arranged in the inner groove (11).

[0036] When the plastic end cover (10) is covered on the end of the light bar (20), the waterproof part (30) is tightly connected to the end of the light bar (20).

[0037] The main inventive concept of the utility model is that the waterproof part (30) can be firmly fixed in the plastic end cover (10) by means of the inner groove (11) provided in the plastic end cover (10); when the plastic end cover (10) is covered on the end of the light bar (20), the waterproof part (30) in the inner groove (11) is in close contact with and adhered to the end of the light bar (20); the waterproof part (30) is glass glue, which as a waterproof material will adhere to the end of the light bar (20); after the glass glue undergoes a curing reaction, it will eventually agglomerate to form an internal and external sealing structure, thereby achieving a sealing effect and providing a reliable waterproof function.

[0038] like Figure 3 As shown, the plastic end cover (10) has a mounting end surface (12), and the mounting end surface (12) is provided with an outer ring rib (121) and an inner ring rib (122), wherein the outer ring rib (121) is arranged around the mounting end surface (12), and the inner ring rib (122) is protruded on the mounting end surface (12).

[0039] The inner groove (11) is formed between the outer ring rib (121) and the inner ring rib (122), and the waterproof portion (30) is arranged between the outer ring rib (121) and the inner ring rib (122).

[0040] like Figures 4 to 5 As shown, the waterproof portion (30) includes an embedded portion (31) and a protruding portion (32), wherein the embedded portion (31) is connected to the bottom of the protruding portion (32).

[0041] The embedded portion (31) is embedded in the inner groove (11) of the plastic end cover (10), and the protruding portion (32) protrudes outside the inner groove (11).

[0042] like Figures 6 to 8 As shown, the end of the light bar (20) is provided with a connecting end surface (21), and the connecting end surface (21) is provided with a connecting portion (211) and a connecting port (212), wherein the connecting portion (211) is arranged around the connecting port (212).

[0043] During specific implementation, the mounting end surface (12) of the plastic end cover (10) corresponds to the connecting end surface (21) at the end of the light bar (20), and the mounting end surface (12) is connected to the connecting end surface (21).

[0044] The inner ring rib (122) on the installation end surface (12) corresponds to the connection opening (212) on the connection end surface (21), and the inner ring rib (122) is inserted into the connection opening (212).

[0045] The outer ring rib (121) of the mounting end surface (12) corresponds to the connecting portion (211) of the connecting end surface (21).

[0046] The protruding portion (32) of the waterproof portion (30) contacts and adheres to the connecting portion (211).

[0047] As described above, during operation, the waterproof portion (30) pre-set in the inner groove (11) of the plastic end cap (10) is in close contact with and adheres to the connecting end face (21) of the light bar (20). When the inner ring rib (122) on the mounting end face (12) is inserted into the connecting port (212) on the connecting end face (21), the protruding portion (32) of the waterproof portion (30) is squeezed and spread out, and is evenly distributed between the connecting end face (21) and the mounting end face (12), forming a sealing structure. During this process, the waterproof portion (30) gradually solidifies, and eventually forms a complete sealing effect between the light bar (20) and the plastic end cap (10), thereby ensuring the stability and reliability of the waterproof performance.

[0048] When implementing it, Figures 9 to 11 As shown, the plastic end cover (10) further includes a back end surface (13), a plurality of fixing ribs (14) and a hardware end cover (40), wherein the hardware end cover (40) is connected to the back end surface (13), and the plurality of fixing ribs (14) are protrudingly provided on both sides of the plastic end cover (10).

[0049] The hardware end cover (40) is provided with a plurality of fixing holes (41), and each of the fixing holes (41) is provided around the hardware end cover (40).

[0050] The connecting end surface (21) at the end of the light bar (20) is also provided with a plurality of rib fixing portions (213) and a plurality of hardware fixing openings (214), and the plurality of rib fixing portions (213) and the plurality of hardware fixing openings (214) are both located on both sides of the connecting end surface (21).

[0051] Each of the fixing ribs (14) on the plastic end cover (10) is connected to the rib fixing portion (213) of the light bar (20) in a one-to-one correspondence.

[0052] Each of the fixing holes (41) on the hardware end cover (40) is connected to the hardware fixing opening (214) of the connecting end surface (21) in a one-to-one correspondence via a fixing piece (42).

[0053] In a specific implementation, when the plastic end cover (10) provided with the waterproof portion (30) is inserted into the light bar (20), each of the fixing ribs (14) of the plastic end cover (10) will be simultaneously inserted into the corresponding rib fixing portion (213) of the light bar (20), and then the fixing member (42) is inserted into each of the fixing holes (41) of the hardware end cover (40) and the corresponding hardware fixing opening (214) of the light bar (20), thereby achieving the effect of squeezing and fixing the plastic end cover (10), further improving the overall sealing and waterproofing effect.

[0054] In practice, the fixing member (42) may be a screw.

[0055] To further understand the present invention, the present invention also provides a waterproof fixing method for a waterproof fluorescent light strip end cap, which includes the following steps:

[0056] The first step is to fill the waterproof portion (30) into the inner groove (11) of the plastic end cover (10) until the waterproof portion (30) slightly protrudes relative to the outer ring rib (121) of the plastic end cover (10), so that the waterproof portion (30) is in a slightly stacked state.
