Technical Examples
  1. A lighting apparatus includes a first source of monochromatic light, a second source of white light, and a third source of polychromatic light. The light from the three sources combine to produce a resultant color of light from the apparatus. The intensities of the light emitted by the first, second and third sources are independently controlled by a controller to produce a desired resultant color of light. Varying the amount of electric current applied to each such light source by substantially an equal amounts to changes the luminance of the combined light with out affecting the resultant color. The lighting apparatus can be operated to replicate a Planckian radiator with a color rendering index of at least 80 throughout a substantial portion of the visible light spectrum produced by the lighting apparatus.
