System for representing colors including an integrating light capsule
First Claim
1. An optical system comprising at least one broad band primary light source and a plurality of primary light modules each comprising a narrow band filter, wherein the narrow band filter modulates the spectral quality of the broad band light source into a narrow band primary light, wherein the emitted narrow band primary lights from the primary light modules comprise unique narrow band lights, wherein the emitted narrow band primary lights are directed to an integrating light mixing chamber, wherein the emitted narrow band primary lights are mixed within the integrating light mixing chamber to form a mixed exit light, and wherein the mixed exit light is projected on to a display surface to display a color on said surface, wherein the integrating light mixing chamber comprises a plurality of first mixing chambers and at least one central mixing chamber and wherein at least one first mixing chamber is associated with only a single emitted narrow band primary light, and wherein each first mixing chamber comprises a plurality of reflecting baffle surfaces.

Abstract
Disclosed herein is a color display device that can be deployed at retail paint stores, kiosks, customers'"'"' offices or homes, airports, malls, etc. for rapid color and appearance prototyping. The color display device, which can be mobile, can display color under standardized lighting or simulated ambient lighting. The color display device can augment or replace a traditional paint chip rack or fan deck. The color display device can manipulate light sources additively and/or subtractively using an integrating light mixing capsule or chamber, special optics, mock objects and electronic control for color and appearance representation and for object illumination with desirable simulated ambient lighting.
