Abstract
Abstract An apparatus for "color mode switching," which enables duplication of daylight chromaticity for each color family. The present invention emits a selected spectral distribution of light which duplicates the effect of daylight, on a color-by-color basis. This effect is accomplished by a specific arrangement of specialized fluorescent and incandescent lamps which are switched (on/off) in a different pattern for each color family. The device has application anywhere color matching is required, including the after market for automobiles.

A device for color mode switching, comprising a plurality of incandescent lamps, and eight first, second, third, fourth, fifth, sixth, seventh and eighth fluorescent lamps have the following chromaticity coordinates, respectively: ______________________________________
x = .438-.442, y = .404-.408
x = .373-.377, y = .378-.382
x = .374-.378, y = .385-.389
x = .343-.347, y = .357-.361
x = .344-.348, y = .357-.361
x = .311-.315, y = .335-.339
x = .311-.315, y = .335-.339
x = .298-.302, y = .310-.314,
______________________________________ wherein said incandescent lamps are switched together, further wherein each of said fluorescent lamps is switched separately, further wherein a first switch controls said incandescent lamps, and a second, third, fourth, fifth, sixth, seventh, eighth and ninth switch controls said first, second, third, fourth, fifth, sixth, seventh and eighth fluorescent lamp, respectively, and further wherein the following switching combinations enable spectral emission of light which substantially duplicates the daylight chromaticity of the following colors: ______________________________________
