Abstract
An underwater lighting fixture adapted for installation in a wall of a swimming pool. The fixture includes a housing having an interior cavity and a transparent cover. A plate is mounted within the housing defines an opening. The plate has a first side facing the transparent cover and a second side opposite the first side. An electric light source includes a reflector positioned at the opening on the second side of the plate so that the reflector is directed toward the transparent cover. A color wheel within the housing is mounted for rotation and has filter segments. A driver mechanism within the housing rotates the color wheel, sequentially positioning successive filter segments to the opening of the plate. An electrical conductor extends through the housing into the interior cavity for delivering power to the electric light source and the driver mechanism.
