This paper describes the improved design of a daylight collector using a fresnelized acrylic dome. Surface inside the acrylic arch is framed to have a concentric and variable crystal that permits low-point light into the mirror tube and that reflects high-edge light, to receive a more constant light output through the span of the day. The prism is placed by a series of circular parallel grooves, with grooves closer the zenith of the cover having cross-areas that are unique in relation to the cross-segments of depressions closer the edges of the cover. Dome works for throughout the day in vertical position to illuminate the inside of a room by utilizing a mirror pipe having mirrored surface inside. Design of the collector improve the efficiency when compare with the conventional dome.

Abstract


This paper describes the improved design of a daylight collector using a fresnelized acrylic dome. Surface inside the acrylic arch is framed to have a concentric and variable crystal that permits low-point light into the mirror tube and that reflects high-edge light, to receive a more constant light output through the span of the day. The prism is placed by a series of circular parallel grooves, with grooves closer the zenith of the cover having cross-areas that are unique in relation to the cross-segments of depressions closer the edges of the cover. Dome works for throughout the day in vertical position to illuminate the inside of a room by utilizing a mirror pipe having mirrored surface inside. Design of the collector improve the efficiency when compare with the conventional dome.
