PURPOSE:To prevent the light leakage in an optical path and the glare by it by reflecting the light from a light emitting section on intermediate reflecting mirrors and a radiation reflecting mirror illuminating a radiated reflected face, providing a lens on the light emitting section, and forming the image of a light emitting body on the radiation reflecting mirror. CONSTITUTION:A lens forming the image of a light emitting body on a radiation reflecting mirror 9 is provided on a light emitting section 3 in a lighting device reflecting the light from the light emitting section 3 with the light emitting body on intermediate reflecting mirrors 6 and 8 and a radiation reflecting mirror 9 illuminating a radiated face for radiation. The width of the light in a optical path is made smaller than the size of a formed image, and the unflared optical path can be formed. When the intermediate reflecting mirrors 6 and 8 changing the direction of the radiation light from the light emitting section 3 are provided and the reflected light from the light emitting section 3 is reflected on the radiation reflecting mirror 9, no leakage light from the intermediate reflecting mirrors 6 and 8 and the radiation reflecting mirror 9 is generated, and the radiated face 2 can be satisfactorily illuminated. |
