An optical assembly for architectural illumination having a quasi point
source surrounded by a collimating ring lens designed to radially project
collimated beams. A segmented off axis parabolic reflector to collect and
reflect light (not gathered by the collimating ring lens) as collimated
beams and a segmented ring reflector, the segments of which are arranged
to gather beams from both the collimating ring lens and the off axis
reflector and then direct them in substantially the same direction.
