201572 · It has been proved that the compound parabolic light concentrator (CPLC) comes very close to being an ide-al concentrator comparing with a cone concentrator or a paraboloid of revolution concentrator[4] . The CPLC pro-vides maximum concentration ratio and almost ideal angle-area tradeoff. It is constructed by overlapping two off-set, …
