PROBLEM TO BE SOLVED: To finish flat the peripheral surface of an opening in a lighting system without generation of an overlapping part of cloth at the peripheral surface when the opening is covered with cloth. SOLUTION: A frame 1 of a lighting system includes a body 1A having a side face 1B where an opening is formed and a cloth inserting part 2 is formed in the side face 1B. A light-transmissible cloth 20 is applied to the undersurface opening of the frame body 1A (A), and the peripheral part of the cloth 20 is wound up along the side face 1B (B), and a cloth portion 20A overlapping when wound up is inserted into the cloth inserting part 2, and in order to maintain such an inserted condition, an engaging groove 20c in the cloth 20, for example, is folded into a channel-form recess 1C in the frame body 1A where an engaging frame 53 is pushed in so that the cloth 20 is fixed to the frame body 1A (D), to finish flat the peripheral surface of the opening, i.e., the side face 1B of the frame.
