Low-power-consumption multifunctional self-luminous signboard capable of displaying interval at night

The invention discloses a low-power-consumption multifunctional self-luminous signboard with a night interval display function, and relates to the technical field of signboards. Comprising a supporting assembly, an inner layer structure used for night display is fixedly connected to the outer wall of the top of the supporting assembly, an outer layer structure used for daytime display is connected between the outer walls of the two sides of the inner layer structure in a sleeving mode, and energy storage assemblies used for electric power conversion are fixedly connected to the outer walls of the two sides of the outer layer structure; the outer walls of the two sides of the inner layer structure are fixedly connected with normally-on assemblies used for illumination display and light reflecting assemblies used for conducting auxiliary illumination on the outer layer structure and the inner layer structure. After the lifting plate descends, when the first radar detects that no pedestrian exists in a certain r
