An apparatus for creating a multi-colored illuminated waterfall includes a waterfall vessel, a clear tube disposed within the vessel, LED bulbs mounted on a circuit board strip which is disposed within the clear tube and a controller circuit which sequentially activates predetermined arrays of different colored LED bulbs. The waterfall vessel has baffles for suppressing turbulence and optional reflective film for enhancing emitted light. A controller circuit is included to sequentially light predetermined arrays of different colored LED bulbs. A rectifier circuit is included to convert a 12 volt ac circuit to a 12 volt dc circuit and a transformer reduces a 110 volt ac power source to a 12 volt ac supply. In an embodiment for a water fountain, the circuit board strip with the LED bulbs are instead disposed within a branch of a tee with a clear lens separating the LED bulbs from the water flow portion of the tee. Water flows into a second branch of the tee and out the third branch of the tee through a discharge tube with a swivel connection at the third branch of the tee to direct the discharge tube through an aperture in a facade. The third branch of the tee includes longitudinal baffles for suppressing turbulence and an optional laminate of reflective film to enhance emitted light. |
