Its basic structure usually includes LED lamp beads, diffuser panels, lamp boards, lamp holders, housings and other components. LED lamps have many advantages such as high efficiency, long life, low energy consumption, and environmental protection, so they are very popular in the field of modern lighting.

[0003] Although LED lamps have many advantages, in actual use, the lamp beads of traditional LED lamps are often fixed to the lamp board by welding or gluing, which is difficult to disassemble. The lamp beads cannot be easily replaced after they are damaged or their lifespan ends, resulting in dark spots in the lighting. Once a failure or damage occurs, the entire LED lamp board usually needs to be replaced. Moreover, the inability to replace the lamp beads also limits the sustainable use time of the lamp. Since the lifespan of LED lamps is usually very long, once a lamp bead failure occurs, it may lead to the early scrapping of the entire lighting equipment, which not only wastes resources but also increases the user's maintenance costs.
