Patent ID: 7434963

Claim:
A lighting system comprising at least first and second lighting subsystems; wherein a. the first lighting subsystem comprises a first array of LEDs, an optical projection structure comprising an optic with constant cross section that is defined by sweeping the cross section along a curve with two end points and a filter associated with the first array of LEDs, the optic comprising a reflector or a refractor, the first array of LEDs configured to generate light in a predetermined wavelength range, the optic and filter configured to substantially filter out light from the first array of LEDs in a predetermined wavelength band and to project the filtered light from the first array of LEDs to a volume space with a predetermined spatial distribution; and b. the second lighting subsystem configured to supplement the first lighting subsystem and comprising a second array of LEDs with one or more optics associated with the second array of LEDs and filter structure associated with the second array of LEDs, the filter structure and optic(s) associated with the second array of LEDs configured to substantially filter out light in the predetermined wavelength band and to project the filtered light from the second array of LEDs to the volume space with a different spatial distribution than the projected light from the first lighting subsystem; c. wherein the first and second lighting subsystems are configured to simultaneously project light to the volume space, so that the light from the second lighting subsystem that is projected to the volume space supplements the light from the first lighting subsystem that is directed to the volume space, and d. wherein the optic comprises a curved reflector segment and the optical projection structure comprises the curved reflector and a refractor; the curved reflector segment and refractor being in a predetermined light collection relationship to each other, and the first array of LEDs having a predetermined location and angular relation to the curved reflector segment and the refractor that is at least partially based on the focal points of the curved reflector segment and refractor and the light collection relationship of the curved reflector segment and the refractor.
