[0079] In a preferred embodiment, a waterproof joint 12 is further included, connected to the second end cover 9, but the present invention is not limited thereto.

[0080] This product integrates the LED lamp and bracket into a single unit, reducing overall size. The bracket also serves as the LED lamp housing, adapting to various mounting methods such as pipe clamps and clamps. Installing the bracket also completes the lamp. This integrated design enhances overall strength and aesthetics. Furthermore, the LED lamp 10 is installed and maintained without the use of screws, improving production efficiency while also eliminating the need for drilling holes in the lamp tube 13, maintaining the integrity of the lamp and preventing cracking.

[0081] The specific implementation of the utility model is as follows:

[0082] The LED connector of the screwless LED lamp 10 of the present invention includes a first end cap 1 and a mounting plate 7 having a lamp board 4. The inner end of the first end cap 1 abuts the first end of the lamp tube 13. The mounting plate 7 is internally mounted within the lamp tube 13. One end of the mounting plate 7 is connected to the end of the first end cap 1, and the other end is provided with a dovetail hook 703. The inner end surface of the second end cap 9 is provided with two L-shaped grooves 906, which are centrally symmetrical about the center point of the inner end surface. The ends of the L-shaped grooves 906 are provided with retaining grooves 907. The dovetail hook 703 is inserted into the L-shaped grooves 906 and rotated to slide into the retaining grooves 907. A third sealing ring 11 is compressed between the second end of the lamp tube 13 and the second end cap 9. The third sealing ring 11, through the lamp tube 13, tightens the LED connector toward the slotted direction of the retaining groove 907, thereby retaining the dovetail hook 703 in the retaining groove 907. The entrance direction of the L-shaped slot 906 is opposite to the opening direction of the limiting slot 907, thereby effectively preventing the dovetail hook 703 from sliding out of the limiting slot 907. The L-shaped slot 906 includes an axial slot 9061 and a radial slot 9062 that are interconnected. The first end of the axial slot 9061 is connected to the inner end surface of the second end cover 9, and one side of the second end is connected to the first end of the radial slot 9062. The second end of the radial slot 9062 is connected to the limiting slot 907. A blocking surface 9071 is formed on one side of the limiting slot 907 to prevent the dovetail hook 703 from sliding. This allows the dovetail hook 703 to contact the blocking surface 9071, enhancing the blocking effect and further preventing the dovetail hook 703 from sliding out of the limiting slot 907. The first end cap 1 is provided with a first annular boss 102, against which the first end of the lamp tube 13 abuts. The second end cap 9 is provided with a third annular boss 902, against which the second end of the lamp tube 13 presses the third sealing ring 11. A first annular step 103, a second annular groove 104, a second annular boss 105, and a second connecting plate 106 are provided between the first annular boss 102 and the inner end of the first end cap 1. The second annular groove 104 is filled with the second sealing ring 3, and the second connecting plate 106 is connected to the first end of the mounting plate 7. The second sealing ring 3 seals against the inner tube of the lamp tube 13. A second annular step 903, a fourth annular groove 904, and a docking seat 905 are provided between the third annular boss 902 and the inner end of the second end cap 9. The end surface of the docking seat 905 is provided with the entrance to an L-shaped groove 906. The mounting plate 7 includes an inclined portion 701, a supporting portion 702 and a dovetail hook 703 connected in sequence. The inclined portion 701 is connected to the light board 4 and a replaceable lens 5 for adjusting the light angle through a screw 6. The supporting portion 702 is provided with a circuit board 8, and the circuit board 8 is electrically connected to the light board 4.

[0083] Figure 7 and Figure 8 This is a schematic diagram of the installation process of the screw-free LED lamp of the present invention. Figure 7 and Figure 8 As shown ( Figure 8To facilitate mechanical blocking, the lamp tube 13 is removed. When a screwless LED lamp is to be installed, a dovetail hook 703 is provided on the mounting plate 7, which assembles with the L-shaped groove 906 on the second end cap 9. The dovetail hook 703 on the mounting plate 7 is inserted into the axial groove 9061 of the L-shaped groove 906 on the second end cap 9 and reaches the radial groove 9062. By rotating the dovetail hook 703 in the radial groove 9062, the dovetail hook 703 on the mounting plate 7 can pass through the L-shaped groove 906 and engage the stop groove 907. Since the third sealing ring 11 will be compressed during the process of inserting the dovetail hook 703 into the L-shaped groove 906, the third sealing ring 11 will always be in a compressed state until the assembly is completed, thereby continuously releasing the elastic pressure. The elastic pressure will lift the lamp tube 13, the first end cover 1 and the mounting plate 7 in turn, and finally be transmitted to the dovetail hook 703 of the mounting plate 7, so that the dovetail hook 703 and the limiting groove 907 are tightly fitted and will not loosen due to vibration. In this process, the third sealing ring 11 can not only play the role of circumferential sealing (circumferentially sealing the gap between the lamp tube 13 and the second end cover 9), but also play the role of an axial elastic member (equivalent to a spring providing elastic force to the lamp tube 13), thereby transmitting pulling force to the dovetail hook 703, forcing the dovetail hook 703 to be at least partially embedded in the limiting slot 907 (the optimal solution is that the dovetail hook 703 is completely immersed in the limiting slot 907), effectively preventing the dovetail hook 703 from sliding out of the limiting slot 907, thereby enhancing the sealing performance of the LED lamp and extending the service life of the LED lamp.

[0084] The light source module and bracket of this utility model are integrated into a whole. The lamp tube serves as both the bracket and the housing, eliminating the need for lamp installation steps and improving installation efficiency. Furthermore, it has a relatively beautiful appearance and a small size. It also enhances the sealing effect of the device, prolonging the life of the LED lamp and its waterproof and dustproof properties.

[0085] In summary, the purpose of the present invention is to provide a screw-free installation LED lamp, which can be used to install or replace the lighting components in the LED lamp without screws, ensure the sealing effect of the device, extend the service life of the LED lamp, and enhance the waterproof and dustproof properties.

[0086] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
