DESIGN OF NONIMAGING OPTICAL CONCENTRATORS AND ILLUMINATORS

摘要

A nonimaging concentrator (50) of light. The concentrator has a shape define d by dR/dphi=Rtanalpha, where R is a radius vector from an origin to a point o f reflection of a light edge ray (70) from a reflector surface (90) and phi is an angle between the R vector and an exit aperture (80) of the concentrator and coordinates (R, phi) represent a point on the reflector surface and alph a is an angle the light edge ray from an origin point makes with a normal to t he reflector surface.
