Patent ID: 7201493

Claim:
An illumination system comprising: a set of a pre-determined number of light emitters arranged along a line with N positions, each light emitter outputting a single color, the arrangement of colors along the line not being formed of symmetrical patterns, the set having at least three subsets of light emitters, each subset including only light emitters that emit substantially the same color, each respective subset having light emitters that output a color different from the light emitters in other subsets, each subset having at least three light emitters, the light emitters of the subset with the fewest number of light emitters, relative to the number of light emitters in each of the remaining subsets in the set, being assigned to respective substantially equidistant positions along the the line of N positions, the subset with the fewest number of light emitters being a first subset, the light emitters of the subset with the second fewest number of light emitters, relative to the number of light emitters in each of the remaining subsets in the set, being assigned to respective substantially equidistant positions along the the line of N positions which are not yet occupied by the first subset, the subset with the second fewest number of light emitters being a second subset, the light emitters of the subset with the third fewest number of light emitters, relative to the number of light emitters in each of any remaining subsets in the set, being assigned to respective substantially equidistant positions along the the line of N positions which are not yet occupied by the first subset or the second subset, the subset with the third fewest number of light emitters being a third subset, except, if the third subset has the greatest number of light emitters in the set, those light emitters in the third subset are assigned to the positions which are not yet occupied.
