ABSTRACT:
A nonimaging concentrator (or illuminator) of light. The concentrator (or illuminator) has a shape defined by dR/d.phi.=Rtan.alpha. where R is a radius vetor from an origin to a point of reflection of a light edge ray from a reflector surface and .phi. is an angle between the R vector and an exit aperture external point of the concentrator (illuminator) and coordinates (R, .phi.) represent a point on a reflector curve and .alpha. is an angle the light edge ray from an origin point makes with a normal to the reflector curve. The reflector surface allows the light edge ray on the reflector curve to vary as a function of position. In the concentrator an absorber has a shape variable which varies with position along the absorber surface.
