摘要

The arrangement collects light from the roof and uses it at desired points in a house. A parabolic mirror (1) mounted on the roof is used to focus the light, which is directed into a parallel beam by a second, smaller mirror (2). The light is passed to the interior of the house via fibreglass cables (3).
