Abstract:
A lighting fixture (1010) has a fluorescent tube (1012) and a plurality of emitters (1022-1032). A color sensor (1016) detects light that has been totally internally reflected within a diffuser (1014) and provides a color feedback signal to a feedback control circuit (1020) to control the light output from the fixture (1012).
