PURPOSE:To make it possible to illuminate a statue of a religious object with a natural light by providing plural sets of ring-form lenses of coaxial glass blocks facing in a specific direction, and dispersing light passages which consist of plural glass blocks. CONSTITUTION:A lens 3 consists of a central circular lens 31, ring-form coaxial lenses 32-34 surrounding the central lens 31 in a circular form, and the like, forming a ring-form lens set as a whole. The focuses of the lenses are designed to coincide to the input end 41 of a photoconductor 4, and the circumferential surfaces a-c of the lenses are formed as conical surfaces with sloped surfaces coincident to the refraction light passage in the lenses. On the other hand, numerous hexagonal glass blocks are combined with lead plates or the like to make light emission holding plates 5 and 6, which transmit the scattered light input from a zenith window and ring-form windows to the downside, while holding focusing light passages. As a result, a statue of a religious object can be illuminated with a natural light, the light is natural compared with an artificial light, and in a specific time, the luminous light can be emitted strongly from the statue itself. |
