Abstract:
A method of manufacturing a collector of light of irradiance I from a radiant source, comprising the steps of:providing a transducer device for collecting the light; andproviding a light reflecting surface by constructing a reflector contour with a family of edge rays defined along a reference line defined by k(t) and forming a shape for said reflector contour relative to said reference line by tracing a vector R(t) to form said shape where t is a scalar parameter position and wherein:R(t)=k(t)+Du(t)where k(t)=a parameterization of said reference line;D=a distance from a point on said reference line to said reflecting surface along a desired edge ray through the point;n=unit vector along a desired direction of said desired edge ray;with said reflector contour reflecting said desired edge ray into actual edge ray a(R(t)), where a is a multidimensional unit vector pointing towards an edge of said radiant light, and said D being the solutions of:dD/dt=((dk(t)/dt).multidot.(a-u)+D(du/dt).multidot.a)/1-a.multidot.u2.
