ABSTRACT:
A portable light fixture which illuminates the volume of water in a swimming pool has the light source and all attendance electrical hardware mounted above the water's surface to avoid the normal measures required to waterproof the light. Light is projected downward into the water through a light shaft which hangs over the edge of the pool and extends down below the water line. The shaft and light element enclosure is opaque. Light travels down the light shaft, traverses the air/water boundary and then exits the light shaft below the water line to a reflective light diffuser suspended within or directly below the shaft exit. The light diffuser spreads the beam away from the pool wall by reflecting the vertical rays exiting the light shaft into a diffuse horizontal beam which then propagates throughout the swimming pool.
