Abstract
A spa lighting apparatus including a wall fitting which seats in an opening in a spa wall and threadably receives a light transmissive lens which includes respective plastic layers providing impact and chemical resistance. The lens is further designed to disperse light from a plurality of LED sources to give an appearance similar to that of a single incandescent source.
Claims19
Spa lighting apparatus comprising:
- a wall fitting having a cylindrical segment sized to fit in a circular opening in a spa wall, the cylindrical segment having a threaded outer surface and a threaded inner surface;
- a light lens having a curved light transmissive surface and a rear cylindrical segment, said rear cylindrical segment having a threaded outer surface for engaging the threaded inner surface of the cylindrical segment of said wall fitting;
- and
- a plurality of light emitting diodes (LED's) mounted within said wall fitting whereby the plurality of LED's appear as a single light source through the light lens.
