PROBLEM TO BE SOLVED: To provide a design lighting system which can enhance lighting efficiency for each of a plurality of design shapes without subjecting a dial to excessive printed lighting control etc. SOLUTION: The angles of inclination of side walls 11d1' to 11d6' of light source housing chambers 11d1 to 11d6 are changed according to design shapes. Namely, the angles of inclinations of the side walls are made sharper for the relatively small design as shown in 13d4 and the angles of inclinations of the side walls are made gentler for the relatively large design as shown in 13d5. Also, the light source housing chambers 11d1 to 11d6 respectively have the design apertures meeting the design shapes. COPYRIGHT: (C)2005,JPO&NCIPI
