PURPOSE:To internally disperse the light from a light source, so as to obtain the emission of desired form by forming a light injection part made out of many air bubbles existing in a light conductive member, and a light source part that injects the predetermined light into the light injection part. CONSTITUTION:A light injection part is formed out of a light conductive plate 1 of acrylic resin, and many small air bubbles 11 exist in the light conductive plate 1, which is formed into a ground glass dispersive surface 12 with its surface side formed as a rough surface, and a reflecting part is formed out of a mirror plate 2, which is arranged on the back surface of the light conductive plate 1. A light source part is composed of a fluorescent tube 31, a socket 32, and of a reflecting plate 33. The light that proceeds within a non-air bubble part is injected into the foam 11, and when it is ejected, the light is dispersed due to the concave lens effect. Since the dispersed light is repeatedly dispersed by the air bubbles 11, the light injected from the light source part generates an internal dispersion, and is ejected in every direction. The light emission in the emission color of each light source part or in a mixed color is possible by selectively outputting the light source part. |
