First Claim
Patent Images
1. A lighting system comprising:
- a light source having light beams emanating therefrom;
a diffraction means for diffracting some of the light from the light source into colored light, the diffraction means having a plane;
directing means for directing some of the colored light onto a ceiling or a wall; and
means for varying the angle between the plane of the diffraction means and the light beams emanating from the light source.

Abstract
An apparatus consisting of a cable grid system for lighting in which a light can be positioned at any location on a ceiling. Optionally, the light fixtures can include a diffraction grating reflector (such as a music CD) to reflect light patterns onto the ceiling from a light source which is preferably a point source. Also, light fixtures with diffraction grating reflectors could be mounted on a wall, table, or on the ceiling without using a cable grid system.
