PROBLEM TO BE SOLVED: To provide a simple lighting device having a chemical light emitting body as a light source capable of concentrating or diffusing light according to usage. SOLUTION: A plurality of inverse V-shaped brittle parts 51-54 are formed stepwise at a part of a body cover 3 composed of a pair of film pieces 31, 32 integrated with a heat seal. A conical "shade" applying the chemical light emitting body as the center axis is formed by ripping off the respective film pieces 31, 32 along the brittle parts 51-54. COPYRIGHT: (C)2004,JPO
