SOLAR IRRADIATION CONCENTRATOR Russian patent published in 2002 - IPC

FIELD: heliotechnology, possibly apparatuses for converting electromagnetic irradiation of Sun to electric, heat or mechanical energy. SUBSTANCE: apparatus includes additional stage of concentration of solar irradiation in the form of mirror wedge 5 mounted on outlet face 7 of concentrator. It provides enhanced degree of concentration of solar irradiation. Behind Fresnel mirror 2 on lower face of prism metallic mirror reflector 3 is arranged. Luminescent matter is applied onto inner surfaces of reflecting devices. EFFECT: enhanced efficiency of concentration of direct and diffuse solar irradiation due to mounting on ends of concentrator two reflecting devices in the form of Fresnel mirrors and due to placing luminescent matter onto inner surfaces of reflecting devices for lowering losses of direct and diffuse solar irradiation. 1 cl, 1 dwg
