Abstract:
A device composed of:a casing;spectral light projecting means arranged in a relative and a corresponding order to each other for projecting a spectral display onto a viewing surface, wherein said spectral projecting means are integrated with rotating motion means arranged coaxially for projecting spectral display in a motion onto said viewing surface;said projecting means are attached to said rotating motion means, thus comprising rotating spectral projecting segments, and rotating upon coaxial based means, and acting together for projecting a desired spectral display in the motion;each of said projecting segments including a light emitting source, light convergent means, and diffraction means for effecting a spectral dispersion of the light rays and projecting same onto said viewing surface; andeach of said rotating motion means providing electrical wiring means, and also a mechanical connection and power means.
