Description

Technical Field

[0002] LED lamps have good energy-saving effects and longer service life. When the lamp beads are well packaged and the lamps are assembled, LED lamps can have good dust and water resistance and can adapt to outdoor working environments. Therefore, they are often used in outdoor lamps, light boxes, and advertising screens.

[0003] In some larger advertising screens, the length or width can reach several meters or tens of meters. For this type of LED screen, it is almost impossible to produce it directly. The usual practice is to splice small module screens to large screens. At some large exhibitions, outdoor stages, outdoor film and television and other event sites, large LED display screens are often temporarily built. When maintaining the LED screen, it may be necessary to disassemble and assemble the LED module. Due to the dense distribution of LED lamp beads inside the LED module and good packaging, the LED module has a high weight. Therefore, additional auxiliary fixation is required during disassembly to prevent it from falling when removing the screws. Additional auxiliary fixation is also required during installation to prevent the LED module from moving before tightening the screws. In this way, the disassembly and installation of the LED module requires auxiliary fixation, and the LED module has the problem of inconvenient disassembly and installation. Utility Model Content
