Abstract
The present teachings relate to semiconductor-based lighting systems and fixtures which process electromagnetic energy from light emitting diodes or the like. A disclosed exemplary system includes at least one occluded remote phosphor and produces substantially white light of desired characteristics. The remote phosphor extends over at least a portion of a surface of a macro optic at an occluded location such that none of the remote phosphor is directly visible through an optical aperture. The phosphor is responsive to electromagnetic energy from a semiconductor device to emit visible light for the emission through the optical aperture.
