Generally speaking, decorative panel decoration is a commonly used decorative method in interior design, which can increase the sense of hierarchy of the interior space and play a role in beautifying the decoration, especially the installation of light strips for lighting on the decorative panels, which can play the role of atmosphere lighting.

[0004] Generally, decorative light strips are installed in decorative light troughs, and decorative light troughs are mostly made on-site and grooved on the ceiling or wall. This not only makes grooving difficult, but also requires laying out lines, using steel rulers, and infrared rays to measure and record the original dimensions, resulting in slow processing efficiency. In addition, there is a lot of dust pollution when cutting wood boards on site, which endangers the health of workers. Grinding will also cause a lot of floating dust to pollute the environment and increase the labor cost of on-site cleaning. Therefore, the importance of dry-made light trough processing on the surface is increasing. For example, the Chinese patent invention patent CN113027032A discloses a finished ceiling integrated light trough design structure, which belongs to the field of building assembly technology. The ceiling stand is fixedly connected to the top surface base.
