[0002] The core of LED color-changing streetlights is the LED chip. When current passes through, electrons and holes recombine in the PN junction, releasing energy and emitting light in the form of electroluminescence. By changing the composition and structure of semiconductor materials and using different packaging technologies, LED chips that can emit light of various colors can be manufactured.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the existing technology, the LED beads and lamp holders of the existing LED lamps are integrated into a single mounting structure, that is, the LED bead PCB board is directly soldered onto the T-shaped lamp holder. When one of the integrated series LED lamps fails, the entire lamp needs to be replaced, resulting in a waste of resources. Utility Model Content

[0004] To avoid waste during the repair of series-connected LED lights, this application provides an LED color-changing street light that is easy to maintain.

[0010] Optionally, the bottom of the light guide column cover is fixedly connected with a claw, and the lamp head has a threaded groove inside, with the inner wall of the threaded groove threadedly connected to the outer wall of the bulb.

[0011] Optionally, the bottom of the light guide column cover is in contact with a light guide snap ring, and the outer wall of the light guide snap ring is provided with a snap groove, the inner wall of the snap groove is snapped with the outer wall of the snap claw.

[0012] Optionally, the bottom of the light guide ring is fixedly connected to the top of the light guide post, and light guide particles are fixedly connected to the outer wall of the light guide post, wherein the number of light guide particles is several.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model comprises a lamp head, a light guide column cover, and an LED PCB board. The LED PCB board is snapped into the light guide column and its cover, forming a structure that can be independently disassembled. When the LED PCB board is damaged, the light guide column can be pulled out by the snap-fit ​​mechanism of the light guide column cover to remove it and replace the LED PCB board. This not only facilitates quick disassembly of the LED PCB board but also ensures that the entire series-connected LED light is used without affecting its operation, avoiding the waste caused by replacing the entire LED light when the PCB board is damaged.

[0015] 2. This utility model incorporates components such as light guide columns and light guide particles. Since the bottom of the light guide column has a concave conical structure, this structure acts as a "concave reflector." When light enters the conical surface from inside the light guide column, it is reflected and refracted in a specific direction, thereby changing the light output angle and redistributing the light to avoid localized over-brightness or under-brightness. Simultaneously, the numerous ring-shaped array of light guide particles on the outer wall of the light guide column scatters the light in all directions, preventing glare caused by direct strong light, resulting in more uniform light output, improved lighting comfort, and enhanced overall lighting effect.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] This application discloses an easy-to-maintain LED color-changing street light. For example... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a main body 1. The front of the main body 1 has an assembly hole 11, which allows the device to be easily hung on the wall. A connecting wire 111 is fixedly connected to the right side of the main body 1. A connector 12 is fixedly connected to the right side of the connecting wire 111. There are two connecting wires 111. A connector 2 13 is fixedly connected to the left side of the connecting wire 111. The connector 12 and connector 2 13 are compatible, allowing several devices to be connected in series through the connector 12 and connector 2 13. A connecting wire 2 14 is fixedly connected to the bottom of the main body 1.

[0023] In this embodiment, the bottom of the connecting wire 214 is fixedly connected to the lamp head 2, the top of the inner wall of the lamp head 2 is in contact with the light guide column cover 22, and a light guide column 32 is provided below the light guide column cover 22. The bottom of the light guide column 32 is set with a concave conical structure, which can redistribute the light and avoid local over-brightness or under-darkness. The inner wall of the light guide column 32 is snapped with the lamp bead PCB board 23.

[0024] Please see Figure 4 As shown, the bottom of the light guide column cover 22 is fixedly connected with a claw 222, and the lamp head 2 has a threaded groove 211 inside. The inner wall of the threaded groove 211 is threadedly connected to the outer wall of the bulb 21, so that the bulb 21 can protect the light guide column 32.

[0025] Please see Figure 2 , Figure 4As shown, a connecting groove 221 is provided on the top of the light guide column cover 22, and a female needle connector 212 is fixedly connected to the top of the inner wall of the lamp head 2. The outer wall of the female needle connector 212 is engaged with the inner wall of the connecting groove 221.

[0026] Please see Figure 4 As shown, the bottom of the light guide column cover 22 is in contact with a light guide snap ring 3, and the outer wall of the light guide snap ring 3 is provided with a snap groove 31, and the inner wall of the snap groove 31 is snapped with the outer wall of the snap claw 222.

[0027] Please see Figure 2 As shown, the top of the connecting groove 221 has a slot hole, and the inner wall of the slot hole contacts the male pin 231. The top of the LED PCB board 23 has an assembly groove, and the inner wall of the assembly groove is fixedly connected to the outer wall of the male pin 231 on the side away from the light guide post cover 22.

[0028] Please see Figure 3 As shown, the bottom of the light guide ring 3 is fixedly connected to the top of the light guide post 32. Light guide particles 321 are fixedly connected to the outer wall of the light guide post 32. There are several light guide particles 321. Several light guide particles 321 can produce a diffuse reflection effect, so that the light no longer presents a strong specular reflection, but is emitted in a soft way, reducing the glare when the human eye observes and improving the lighting comfort.

[0029] Please see Figure 3 As shown, LED beads 232 are fixedly connected to the bottom of the LED PCB board 23, and the outer wall of the male pin 231 is engaged with the inner wall of the female pin connector 212.

[0030] The implementation principle of an easy-to-maintain LED color street light according to an embodiment of this application is as follows: By snapping the LED PCB board 23 into the light guide post 32 and the light guide post cover 22, a structure that can be independently disassembled is formed. When the LED PCB board 23 is damaged, the bulb 21 is unscrewed first. Then, by pulling the light guide post 32, the light guide post cover 22 is released from the restriction of the female pin connector 212, and the male pin 231 is pulled out from the female pin connector 212. Since the light guide post cover 22 and the light guide snap ring 3 are snapped together through the connecting groove 221 and the snap groove 31, the light guide post cover 22 can be quickly disassembled. This not only facilitates the quick disassembly of the LED PCB board 23, but also allows for the rapid disassembly of the LED PCB board 23. Removing and replacing the LEDs does not affect the use of the entire series LED light, avoiding the waste caused by replacing the entire LED PCB board 23 if it is damaged. Since the bottom of the light guide column 32 is a concave conical structure, it acts as a "concave reflector". When light enters the conical surface from the inside of the light guide column, it will be reflected and refracted in a specific direction, thereby changing the light output angle and redistributing the light to avoid local over-brightness or under-brightness. At the same time, the light guide particles 321 arranged in a ring array on the outer wall of the light guide column 32 can scatter the light in all directions, avoiding glare caused by direct strong light, making the light output more uniform, improving the comfort of lighting, and improving the overall lighting effect of the device.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
