Rotating spectral display device

摘要

A solar powered rainbow-making device produces a visual display that is created by the interplay of light and a light refractive element that form constantly changing patterns from a rotating crystal. The rotating display device includes a circular-shaped refractive element that is mounted on a base and is turned by a motor driven transmission gear train. The crystal rotates about a horizontal axis as sunlight is transformed into a color spectrum that moves in a circular fashion. The color images can include a plurality of distinct rainbow images that are projected onto the walls and other structures in the immediate environment.

主权项

1. A rotating spectral display device that comprises:
a base; a drive system that is positioned within the base and that includes a motor and a drive wheel; a cylindrical ring having a perimeter that is engaged to the drive wheel such that movement of the drive wheel rotates the cylindrical ring; an optically refractive element operative to refract sun light to produce an optical spectrum, wherein the optically refractive element is secured to the cylindrical ring so as to rotate about a horizontal axis; and a source of energy that is operatively connected to the motor.
