2 The rays are then concentrated and set upon their journey down "light guides" that direct light through the building. O Rays of sunlight are redirected toward the building by "collector panels" that incorporate an array of lenses that move in unison to track the sun. Prism tube Sunlight 3 These "light guides" are hollow structures that use prismatic films to efficiently transport large quantities of light by constantly reflecting it. Contrary to conventional systems that use mirrors, no light escapes through the walls and very little light is absorbed by the pipe because light travels primarily in the air space within the hollow guide. Prism guides are also very lightweight, thus making them highly cost-effective. MATTHEW BAMBACH/THE GLOBE AND MAIL ยป SOURCES: SUNCENTRAL, INC.; CONTROLLEDENVIRONMENTS.ORG
