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.

Claims

1. 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:

space="preserve" listing-type="tabular">______________________________________ 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;

2. The device according to claim 1 wherein aid first, second, third, fourth, fifth, sixth, seventh, and eighth fluorescent lamps have the following chromaticity coordinates and correlated color temperature:

space="preserve" listing-type="tabular">______________________________________ x = .440, y = .406, 3,000°

K. x = .375, y = .380, 4,000°

K. x = .376, y = .387, 4,100°

K. x = .345, y = .359, 5,000°

K. x = .346, y = .359, 5,000°

K. x = .313, y = .337, 6,250°

K. x = .313, y = .337, 6,250°

K. x = .300, y = .312, 7,500°

K. ______________________________________

3. The device according to claim 2 wherein each of said lamps comprises a light panel included within a housing body, said housing body having housing doors having a reflective surface on the inner surfaces thereof.

4. The device according to claim 2 wherein said housing body is provided with a housing bracket, a housing mount rotatably attached to said housing bracket, wherein said housing mount is fixedly attached to a ratchet cooperatively engaged with a ratchet rod affixed to a base.
