PROBLEM TO BE SOLVED: To diversify display and to enhance the degree of freedom to dispose a light source. SOLUTION: This device is equipped with a mirror ball body 1, an irradiating part 3 and a rotating part 4. The mirror ball body 1 is a polyhedron formed by sticking reflecting plate pieces 11 to a hollow sphere of synthetic resin. The radiating part 3 is equipped with a light source 31, a light guide 32 and a radiator 33. The light guide 32 is composed of optical fiber, and guides light from a light source to the radiator. The radiator 33 is structured by providing many communicating holes in a flat plate 331 so as to form a designated shape and inserting one end 321 of the optical fiber. Since this device projects light on the periphery of a figure such as a letter shape, more diversified expressions can be directed in comparison with a conventional method by light points with an equal interval. Since the light source 31 is connected to the irradiator 33 by the light guide 32 of optical fiber, the both can be freely disposed. |
