METHOD AND APPARATUS FOR CONTROLLING DIFFUSION AND COLOR OF A LIGHT BEAM

摘要

A light fixture (100) including a flexible diffusion material (310) coupled to a scrolling mechanism (110) capable of positioning a selected portion of the diffusion material in a light beam (112) from a light source (102). Different portions (O-T) of the diffusion material (310) provide differing amounts of diffusion. The scrolling mechanism (110) may be remotely operated to produce a desired amount of diffusion in the light beam. The light fixture (100) may also include one or more additional scrolling mechanisms (106, 108) coupled to flexible color filter material (306, 308), such that the light beam (112) may be filtered to a desired color. The additional scrolling mechanisms (106, 108) may be remotely operated to produce color filtration of a predetermined color or saturation. A non-scrolling holographic diffusion material (1206) may be removably mounted to a light fixture (1100) having a scrolling mechanisms (1106) coupled to flexible color filter material.
