Furthermore, the LED lamp 10 is screw-free during installation and maintenance, improving productivity while eliminating the need for drilling holes in the lamp tube, maintaining its integrity and preventing cracking.

[0090] The specific implementation of the utility model is as follows:

[0091] See also Figures 1 to 6The LED connector in the quick-install LED lamp 10 of the present invention includes a first end cap 1, a mounting plate 7, and a lamp board 4. A second sealing ring 3 is provided around the circumference of the first end cap 1. The inner end of the first end cap 1 is inserted into the first end of the lamp tube 13. The mounting plate 7 is built into the lamp tube 13. The first end of the mounting plate 7 is connected to the end of the first end cap 1. The lamp board 4 is set on the mounting plate 7. Light from the lamp board 4 penetrates the lamp tube 13 and is emitted outward. Another second sealing ring 3 is provided around the circumference of the second end cap 9. The inner end of the second end cap 9 is inserted into the second end of the lamp tube 13 and is detachably connected to the second end of the mounting plate 7. The first end cap 1 and the second sealing ring 3 are respectively circumferentially sealed with the inner walls of the two ends of the lamp tube 13, and the mounting plate 7 is suspended in the lamp tube 13. From the outer end to the inner end of the first end cover 1, a first annular step 103, a second annular groove 104, a second annular boss 105, and a second connecting plate 106 are formed in sequence. The second annular groove 104 is filled with a second sealing ring 3, and the second connecting plate 106 is connected to the first end of the mounting plate 7. From the outer end to the inner end of the second end cover 9, a second annular step 903, a fourth annular groove 904, and a docking seat 905 are formed in sequence. The second end of the mounting plate 7 is detachably connected to the docking seat 905, and the outer end of the second end cover 9 is connected to a waterproof joint 12. A docking seat 905 is provided at the inner end of the second end cover 9. The mounting plate 7 includes an inclined portion 701, a bearing portion 702, and a docking portion 703, which are connected in sequence. The inclined portion 701 is connected to the light board 4 and a replaceable lens 5 for adjusting the light angle by screws 6. The bearing portion 702 is provided with a circuit board 8, which is electrically connected to the light board 4. The docking portion 703 is connected to the docking seat 905.

[0092] It can be seen that when the lighting range of the light source needs to be adjusted, the LED connector can be pulled out of the lamp tube 13 and replaced with another LED connector with a wider or narrower lighting range, thereby completing the adjustment of the lighting range of the LED lamp 10 without tightening screws. If the lamp board 4 of the LED connector is damaged, the above steps can also be followed to pull out the LED connector and replace it with a good LED connector, thus quickly completing the maintenance of the LED lamp 10.

[0093] See also Figure 7 、 8The identification lamp of the present invention adopts an identification lamp pole 14 and the above-mentioned quick-install LED lamp 10. The identification lamp pole 14 is provided with at least one lighting opening 15 and an alignment hole. The identification lamp pole 14 is provided with a lighting opening 15. The quick-install LED lamp is inserted into the inner tube of the identification lamp pole 14 so that at least part of the lamp tube 13 is exposed in the lighting opening 15. The first end cover 1 or the second end cover 9 of the LED lamp is provided with a positioning hole 17. The positioning pin 18 passes through the alignment hole and is plugged into the positioning hole 17 of the LED lamp to position the LED lamp in the inner tube of the identification lamp pole 14. The light emitted through the lighting opening 15 illuminates the range where the identification plate 16 is located. A first annular groove 101 and a first annular boss 102 are formed in sequence from the outer end of the first end cover 1 to the middle of the first annular step 103. A third annular groove 901 and a third annular boss 902 are formed in sequence from the outer end of the second end cover 9 to the second annular step 903. The first annular groove 101 and the third annular groove 901 are each embedded with a first sealing ring 2. The first sealing ring 2 forms an annular damping limiter with the inner tube surface of the identification lamp pole 14, thereby preventing the LED lamp 10 from rolling in the inner tube of the identification lamp pole 14. In addition, the third sealing ring 11 is sleeved on the outer periphery of the second end cover 9. The third sealing ring 11 can elastically seal the gap between the lamp tube 13 and the third annular boss 902. When replacing identification plates 16 of different sizes, it is necessary to adjust the lighting range of the LED lamp 10 accordingly. At this time, it is necessary to first remove the positioning pin 18, pull the LED lamp 10 out of the inner tube of the identification lamp pole 14, and then refer to the above-mentioned steps for replacing the LED connector of the LED lamp 10 to replace the LED connector of the corresponding lighting range. Finally, the replaced LED lamp 10 is reinserted into the inner tube of the identification lamp pole 14 and positioned by the positioning pin 18.

[0094] This new light source module and bracket are integrated into a single unit, with the lamp serving as both the bracket and the housing. This eliminates the need for installation steps and improves installation efficiency. Furthermore, the design is aesthetically pleasing and compact. This new light source is also compatible with various lens angles, eliminating the need to change the fixture. By simply changing the lens, it can be used to match signage of varying sizes, achieving varying illumination ranges.

[0095] In summary, the purpose of the present invention is to provide a quick-install LED lamp that can install or replace lighting components in the LED lamp without screws, thereby speeding up the installation of the LED lamp, greatly reducing the work steps and labor costs of repairing and upgrading the LED lamp, and improving the user experience.

[0096] 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.
