Patent 7322156 was granted and assigned to Solatube International, Inc. on January, 2008 by the United States Patent and Trademark Office.
A skylight cover includes a transparent lens and an opaque reflector attached to the inside of the cover opposite the lens. Light entering the lens can be refracted by the lens so that it reflects off of the reflector and into a tubular skylight assembly. Thus, the amount of light entering the tubular skylight assembly is maximized.
