Abstract
An elongated open ended tube has a square or rectangular cross-section and light reflecting inner surfaces. The tube is formed with flat semi-rigid side walls flexibly connected at the corners for collapsing or folding the tube between a generally flat storage and shipping position and an expanded tubular position for installation. The tube extends within an attic of a building with its upper open end portion covered by a light transmitting skylight attached to the roof of the building and its lower open end portion covered by a light transmitting and diffusing panel or lens attached to a ceiling of the building.
