Abstract

PURPOSE:To provide a structure with which multiple reflection illumination can be carried out while the brightness of a light source is maintained. CONSTITUTION:A transparent intermediate reflecting plate 14 on which a picture 13 is formed by etching or engraving is arranged between an upper mirror 11 and a lower half mirror 12 in a lighting system. A light source 15 for edge- lighting the intermediate reflecting plate 14 is provided, and the light diffracted in a complicated manner by means of the picture 13 on the intermediate reflecting plate 14 goes from the intermediate reflecting plate 14 to the upper mirror 11 and is reflected by the mirror, and is further reflected by the lower half mirror 12. Multiple reflection type illumination can be achieved by repeating these processes, and since the light from the light source 15 is not transmitted through the mirror at the time, transmission loss of light is not caused on the point, and multiple reflection type illumination can thus be carried out while the light from the light source 15 is maintained bright.
