At this time, the spring 402 is in a compressed state, and the lamp housing 3 is pulled until it is separated from the backlight source body 1. When the staff needs to install the lamp housing 3, the lamp housing 3 is pushed The limit block 403 is driven to move until the position of the limit block 403 is aligned with the sliding hole 404, and the elastic force of the spring 402 drives the limit slide to automatically insert into the sliding hole 404, thereby facilitating the disassembly of the backlight source body 1 and the lamp housing 3.
