| Title: |
Method For Controlling The Luminous Flux Spectrum of a Lighting Fixture |
| Abstract: |
A method is disclosed for controlling a lighting fixture of a kind having
individually colored light sources, e.g., LEDs, that emit light having a
distinct luminous flux spectrum that varies in its initial spectral
composition, that varies with temperature, and that degrades over time.
The method controls such fixture so that it projects light having a
predetermined desired flux spectrum despite variations in initial
spectral characteristics, despite variations in temperature, and despite
flux degradations over time.
