Abstract: 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.

Abstract: A tubular skylight is supported in a building between the ceiling and the roof of the building by a support ring that is connected to the ceiling joists or to the ceiling dry wall. Specifically, a tube ring is engaged with the tube of the skylight to in turn engage the support ring and thereby support the tube. Also, the skylight includes a cover seal that establishes a seal between the roof dome of the skylight and the tube, and that also spaces the flashing of the skylight from the tube to prevent galvanic corrosion and to inhibit heat transfer between the flashing and the tube. The tube includes an upper segment that receives a lower segment, and an expansion seal is positioned between the segments such that the segments can move relative to each other to absorb thermal stresses, with the expansion seal maintaining a seal between the segments.

Abstract: The present invention includes an improved tubular skylight system having a clear acrylic outer dome, an aluminum flashing, an aluminum light tube, an aluminum ceiling plaster ring, and a prismatic diffuser. The outer dome includes an aluminum ring around the base of the dome which contains a circular channel and holes which provide for increased heat dissipation and condensation removal. The aluminum ring allows the outer acrylic dome to be attached directly to the flashing thereby substantially decreasing the risk of crack formation in the acrylic dome. Moreover, the surface of the acrylic dome is imprinted to refract, a substantially increased amount of the natural light down into the light tube.The lower end of the light tube extends to the inside surface of the ceiling thereby substantially increasing the dispersion of the light rays entering the building.
