Device for projecting a dynamic spectral display

Abstract

A device for projecting spectral display onto a viewing surface, having numerous light projecting segments attached to rotating hollow shafts, mounted and rotating upon each other on coaxial based shaft. The projecting segments include a light emitting source to produce light rays, a light convergent member such as lens and a diffraction member such as prism or diffraction gratings, for effecting spectral dispersion of the light rays for projecting same onto viewing surface to create the spectral display in a motion or a dynamic spectral display. The rotating hollow shafts provide built-in electrical wiring tracks and a connection to energize the light source, and they also provide mechanical connection through geared wheel to receive power to effect the rotating motion. The projecting segments with their respective rotating shafts are accommodated inside a casing or a housing of the device, which can be individual or portable. The device can also be incorporated, fasten down or mounted to the a wall, a ceiling and operate within architectural spaces. Depending on the number of the light projecting segments and their specific structure or design, the spectral display in one embodiment creates an image of spectral clock's dial display, and in another embodiment the spectral display forms artistic, abstract display in the motion of the dynamic spectral display.
