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. The lower end of the light tube also sits on the plaster ring thereby substantially reducing the accessability of dust, water and bugs inside the building. The upper end of the light tube is reciprocally received into the flashing, but the outer dome attaches directly to the flashing. Consequently, the light tube "floats" inside the flashing thereby providing a more flexible system to compensate for "roof sag." Moreover, the floating light tube allows the manipulation of the flashing (i.e., to replace shingles) without the need to disassemble the entire system.
