Abstract
Methods and apparatus for illumination of liquids in a variety of environments. In one example, multi-color LED-based light sources are employed to achieve a wide range of enhanced lighting effects in liquids. In another example, a pool or spa is illuminated by one or more multi-color light sources that may be employed as individually and independently controllable devices, or coupled together to form a networked lighting system to provide a variety of programmable and/or coordinated color illumination effects in the pool or spa environment.

23. An apparatus, comprising:
-
one of a pool and a spa to contain a liquid; and
at least one light source, supported by the one of the pool and the spa, to illuminate the liquid, wherein the at least one light source is adapted to generate radiation of different colors without requiring the use of a color filter.

-
24. A method for illuminating a liquid, comprising an act of illuminating the liquid with radiation output simultaneously by at least two differently colored LEDs.
-
25. A method for illuminating a liquid in one of a pool and a spa, comprising an act of illuminating the liquid in one of the pool and the spa with radiation output by at least one LED.
-
26. A method for illuminating a liquid in one of a pool and a spa, comprising an act of illuminating the liquid with radiation output by at least two independently controllable light sources disposed together in a housing coupled to the one of the pool and the spa.
-
27. A method for illuminating a liquid, comprising an act of illuminating the liquid with radiation output by at least one light source, wherein the at least one light source is adapted to generate radiation of different colors without requiring the use of a color filter.
