Corrugated bent three-dimensional light curtain lamp box and decorative suspended ceiling

The invention relates to a corrugated bent three-dimensional light curtain lamp box and a decorative suspended ceiling. Each lamp box comprises a truss and a lamp box framework arranged below the truss. The trusses comprise a transverse truss, a longitudinal truss and a vertical truss; the lamp box framework comprises a transverse framework, a longitudinal framework, a vertical framework and a connecting framework; the trusses and the lamp box framework are designed into different corrugated bending shapes according to design requirements, specifically, the longitudinal trusses are provided with corrugated bending line types according to design, and the longitudinal frameworks are provided with the same corrugated bending line types in the corrugated bending extending direction of the longitudinal trusses. A light-transmitting film covers the outer part of the lamp box framework along the edge of the lower end surface of the truss; and a luminous source is arranged in the light-transmitting film.
