ABSTRACT:
A tubular skylight having an improved dome improving the efficiency of the skylight and reducing the shadows cast by the skylight. The dome includes a substantially vertical rear face having an integral prism in a portion of its outer surface, and the rear face is offset inwardly from the perimeter of the reflective tube, thus allowing light to escape from the bottom edge of the rear face downwardly into the reflective tube. The integral prism does not extend to the top or front face of the dome, thus reducing the prevalence of shadows created by light rays entering the dome through the prism.
