Patent abstract
A skylight shaft is coated with a highly reflective film to maximize the amount of light transmitted from the top of the skylight to a room below the skylight. Surface irregularities are formed in the shaft or adhesive that holds the film onto the shaft to diffuse the light and thereby prevent the formation of focal “hot spots” in the room below.
