<P>PROBLEM TO BE SOLVED: To direct sound and light with the feeling of unity by diffusing them into space by the same reflection mechanism in the state of matching sound and illumination, to achieve two functions of the sound and the illumination simultaneously by a single apparatus, and to save space. <P>SOLUTION: A reflector which effectively acts on both sound and light is used as a common mechanism for reflecting the sound and luminous fluxes. <P>COPYRIGHT: (C)2009,JPO&INPIT |
