ABSTRACT:
An illumination system, reflector and method for producing a beam with a substantially circularly symmetric irradiance distribution from a light source having a plurality of linear light emitting elements arranged with their longitudinal axes substantially parallel with each other and spaced substantially symmetrically about a central longitudinal axis. The reflector includes a plurality of reflecting zones corresponding to, and aligned with, the plurality of light emitting elements. A surface of a reflecting zone may be defined by rotating a generator curve around an axis of rotation that is not coaxial with the longitudinal axis of the light source.
