Light-collecting skylight cover

摘要

A roof-mounted cover for a tubular skylight includes a dome and a frusto-conical skirt depending downwardly from the dome. The skirt defines an open circular periphery, and plural circular grooves are formed on the inside surface of the skirt parallel to the periphery. The grooves direct light into a vertical reflecting tube that is in communication with the cover, and the light propagates downwardly through the tube and through a ceiling-mounted light diffuser to illuminate an interior room of the building on which the cover is mounted.
