<p>The system (10) has a light fixture (11) for illuminating buildings or partial surfaces, goods or objects. The fixture has a set of light sources e.g. red LED (18), for generating light of different colors. A controller e.g. computer, adjusts the light emitted by the sources. The fixture produces a total light output as a sum or mixture of the light emissions of the sources. The controller has a color selector (26) for setting the color of the light output, and has a balancer (27) for retaining a set color of the light output when a light output of one of the light sources is changed.</p> |
