PROBLEM TO BE SOLVED: To provide a lighting system capable of illuminating uniformly toward substantially the entire periphery of an inspection object W.SOLUTION: The lighting system 1 includes a bendable sheet-like light source 2, having a light emitting surface 25 bent toward the inside, which is used for visual inspection or the like of the inspection object W including a three-dimensional object having a three-dimensional shape; and a bending angle adjusting machine 3 for holding the sheet-like light source 2 in the bendable state, and adjusting its bending angle. The bendable sheet-like light source 2 has a three-layered structure having an electroluminescence sheet 21, a diffusion sheet 22 and a Japanese paper 23. |
