US patent number 7,229,027 is for a waterfall producing device that incorporates a light chamber to house LED lights to illuminate the water stream coming from the waterfall.
The second patent, US patent number 7,244,037, is for a detachable LED pool light that builds upon prior Nexxus Lighting patented technology that provides for an LED lighting fixture to be installed into the wall of the pool without a niche, and features an underwater connector that allows the light fixture to be connected or disconnected while the light is submerged in water with the power off.
"Illuminated waterfalls are used in a number of applications including swimming pools, portable spas and fountains," stated Steve Faber, Nexxus Lighting's director of engineering. "Incorporating LED lighting into these devices provides unique ways to produce water lighting effects that customers are looking for. The detachable pool light patent builds upon our niche-less pool lighting designs and provides an added disconnection service feature that no one else can offer."
