Abstract
A light fixture for underwater use in swimming pools has a waterproof gasket between the lens and the housing enclosing the electrical components. The gasket is fabricated of an off-white, neoprene material and is devoid of any coloring agents, such as carbon black, which are subject to leaching by chlorine-containing water in the pool. As a result, discoloration of the wall of the pool and also of the lens will not occur, even where chlorine concentrations are relatively high.
Claims8
In an underwater lighting assembly having a housing adapted to be mounted in the wall of the structure for confining a body of water containing a significant quantity of a chlorine compound, said housing being provided with an opening for light rays to illuminate the area of the water surrounding the assembly and a translucent lens removably mounted on the housing in closing relationship to said opening, the combination with said housing and lens of:
- a gasket configured to close the space between the housing and the lens and provide a water tight seal therebetween,
- said gasket being positioned such that it is in contact with the water confined by said structure when in its operative water sealing disposition,
- the gasket being fabricated of a synthetic elastomeric material which is resistant to deterioration over long periods of exposure to water containing a chlorine compound,
- said material being devoid of a coloring agent such as carbon black which is subject to leaching from the gasket when exposed over a time period to a chlorine compound bearing quantity of water.

- said gasket being positioned such that it is in contact with the water confined by said structure when in its operative water sealing disposition,
- the gasket being fabricated of a synthetic elastomeric material which is resistant to deterioration over long periods of exposure to water containing a chlorine compound, and having a plurality of apertures formed therethrough for receiving clamping bolts,
- said material being devoid of a coloring agent such as carbon black which is subject to leaching from the gasket when exposed over a time period to a chlorine compound bearing quantity of water.
