`
`the foregoing applications is hereby incorporated herein by reference.
`
`Field of the Invention
`
`20
`
`The present invention relates generally to illumination and lighting control. More
`particularly, the present invention is directed to methods and apparatus for illumination
`
`of liquids, including illumination of liquids in environments such as pools or spas.
`
`Background
`
`25
`
`Conventional lighting for various space-illumination applications (e.g.,
`
`residential, office/workplace, retail, commercial, industrial, recreational, sporting,
`
`entertainment and outdoor environments) generally involves light sources coupled to a
`
`source of power via manually operated mechanical switches. Some examples of
`
`conventional lighting include fluorescent, incandescent, sodium and halogen light
`
`30
`
`sources. Incandescent light sources (e.g., tungsten filament light bulbs) are perhaps most
`
`commonly found in residential environments, while fluorescent light sources (e.g.,
`
`ballast-controlled gas discharge tubes) commonly are used for large lighting installations
`
`
`
`Page 24 of 83
`
`

`
`- 3-
`
`in office and workplace environments, due to the high efficiency (high intensity per unit
`power consumed) of such sources. Sodium light sources commonly are used in outdoor
`environments (e.g., street lighting), and are also recognized for their energy efficiency,
`whereas halogen light sources may be found in residential and retail environments as
`5 more efficient alternatives to incandescent light sources.
`Unlike the foregoing lighting examples, light emitting diodes (LEOs) generally
`are semiconductor-based light sources often employed in low-power instrumentation and
`appliance applications for indication purposes. LEOs conventionally are available in a
`variety of colors (e.g., red, green, yellow, blue, white), based on the types of materials
`used in their fabrication. This color variety of LEOs recently has been exploited to
`create LED-based light sources having sufficient light output for new space-illumination
`applications.

`6,150,774, U.S. Patent No. 6,166,496, U.S. Patent No. 6,211,626, and U.S. Patent No.
`6,292,901, each of which patents is incorporated herein by reference, multiple
`differently-colored LEOs may be combined in a lighting fixture, wherein the intensity of
`the LEOs of each different color is independently controlled (e.g., varied) to produce a
`number of different hues. In one example of such an apparatus, red, green, and blue
`LEOs are used in combination to produce literally hundreds of different hues from a
`single lighting fixture. Additionally, the relative intensities of the red, green, and blue
`LEOs may be computer controlled, thereby providing a programmable multi-color light
`source.
`
`Furthermore, as discussed in the aforementioned patents, and additionally in co(cid:173)
`pending U.S. patent application Serial No. 09/870,193, filed May 30, 2001, entitled
`25 METHODS AND APPARATUS FOR CONTROLLING DEVICES IN A
`NETWORKED LIGHTING SYSTEM, incorporated by reference herein, individual
`computer controllable LED-based multi-color light sources may be adapted to be
`coupled together to form a networked lighting system, wherein each light source is
`independently addressable. In such a network, one or more illumination programs may
`be executed to strategically route lighting data to any one or more of the independently
`addressable LED-based multi-color light sources, so as to generate a wide variety of
`dynamic lighting effects.

`
`Detailed Description
`
`Applicants have recognized and appreciated that multi-color LED-based light
`
`sources may be adapted to illuminate liquids in a variety of environments (e.g.,
`
`15
`
`entertainment, recreational, sporting, therapeutic, utilitarian, etc.) to achieve a wide range
`
`of enhanced lighting effects. For example, as discussed in a number of the U.S. patents
`
`and patent applications referenced above, multi-color LED-based light sources may be
`
`employed to produce a variety of enhanced lighting effects in pools or spas, as well as in
`
`other liquid environments. It should be appreciated that the various concepts, methods,
`
`20
`
`apparatus, and systems disclosed in any of the patents and patent applications referenced
`
`herein may be applied in various embodiments of the present invention discussed further
`
`below directed to the illumination of liquids.
`
`Prior to the introduction of multi-color LED-based light sources in pool or spa
`
`environments (as disclosed in U.S. Patent Nos. 6, 016, 038 and 6,166,496, for example),
`
`25
`
`pools and spas conventionally were illuminated using standard white light incandescent,
`
`fluorescent or halogen lamps. In some cases, pool or spa light fixtures including
`
`conventional white light sources are assembled with one or more color filters, in an effort
`
`to add color to the light generated by the conventional white light sources. In particular,
`
`some conventional pool or spa light fixtures include a number of movable color filters to
`
`30
`
`provide variable color light. In yet other conventional pool or spa lighting systems, fiber
`
`optics may be employed to distribute light around the edge of a pool or spa, wherein one
`
`
`
`Page 29 of 83
`
`

`
`- 8-
`
`end of the fiber optic may be coupled to a conventional white light source generating
`
`light through one or more color filters.
`
`Unlike the foregoing conventional systems for illuminating a pool or spa using
`
`conventional white light sources and color filters, Applicants have recognized and
`
`5
`
`appreciated that light sources other than conventional white light sources may be
`
`particularly adapted and employed to provide multi-color radiation for a variety of liquid
`
`illumination applications. Accordingly, one embodiment of the present invention is
`
`directed generally to novel methods and apparatus for illumination of liquids.
`
`For example, in one embodiment of the invention, one or more multi-color LED-
`
`10
`
`based light sources are employed to provide enhanced color illumination effects in liquid
`
`environments. In one aspect, multi-color LED-based light sources for illumination of
`
`liquids generally do not require the use of a color filter to produce color illumination
`
`effects. However, it should be appreciated that one or more color filters optionally may
`
`be employed with LED-based light sources, as well as other types of light sources, for
`
`15
`
`illumination of liquids according to various embodiments of the invention. Additionally,
`
`LED-based multi-color light sources optionally may be used in conjunction with a fiber
`
`optic light distribution system for various liquid illumination applications, according to
`
`one embodiment of the invention.
`
`Examples of liquid environments that may be illuminated according to various
`
`20
`
`embodiments of the present invention include, but are not limited to, pools, spas, tubs,
`
`basins, sinks, water baths, water tanks, fish tanks, aquariums, waterfalls, and fountains.
`
`In one aspect of the invention, one or more light sources may be employed to provide
`
`enhanced color illumination effects for essentially standing (e.g., stationary) liquids as
`
`well as flowing liquids, and similarly may be used to illuminate ice, water vapor, rain,
`
`25 mist, fog, and the like, whether naturally occurring or man made (e.g., produced by a
`
`machine). More generally, in various aspects of the present invention, one or more light
`
`sources may be used to illuminate any of a variety of liquids that allow radiation
`
`generated by the light sources to be at least partially transmitted or reflected.
`
`One embodiment of the present invention is particularly directed to illuminating a
`
`30
`
`liquid in a pool or spa. According to various aspects of this embodiment, one or more
`
`multi-color light sources may be employed in a pool or spa environment. In one aspect,
`
`such multi-color light sources may be individually and independently controllable (i.e.,
`
`
`
`Page 30 of 83
`
`

`
`- 9-
`
`"stand-alone") devices that each generates multi-color illumination in the liquid
`
`contained in the pool or spa. Alternatively, two or more independently controllable and
`
`independently addressable multi-color light sources may be coupled together to form a
`
`networked lighting system, to provide a variety of programmable and/or coordinated
`
`5
`
`color illumination effects in the pool or spa environment. Specifically, in one
`
`embodiment, two or more multi-color light sources coupled together in a networked
`
`\ighting system may provide dynamic variable color lighting effects in all or only
`
`\
`
`particular sections or portions of a pool or spa.
`
`Additionally, according to one embodiment, one or more multi-color light
`
`1 o
`
`sources in a pool or spa environment may be remotely controlled to facilitate a number
`
`ofliquid illumination applications. In one aspect of this embodiment, one or more multi(cid:173)
`
`color light sources in the pool or spa environment may be remotely controlled via one or
`
`more remote user interfaces. In another aspect, one or more multi-color light sources
`
`may be remotely controlled based on one or more interruptions in the power supplied to
`
`15
`
`the light source(s). In yet another aspect, one or more light sources in the pool or spa
`
`environment may be remotely controlled based on information obtained from one or
`
`more sensors adapted to output signals in response to one or more detectable conditions
`
`in the pool or spa environment. In yet another aspect, one or more light sources in the
`
`pool or spa environment may be remotely controlled based on information obtained from
`
`20
`
`a data network, such as the Internet, for example.
`
`In another embodiment of the invention, one or more multi-color light sources in
`
`the pool or spa environment may be particularly adapted to execute one or more dynamic
`
`variable color illumination programs. In one aspect of this embodiment, the selection of
`
`a particular dynamic illumination program from a number of such programs may be
`
`25
`
`indicated to the user via the radiation generated by the one or more light sources. In
`
`particular, in one aspect, the selection of a particular dynamic illumination program may
`
`be indicated by temporarily modifying one or more variable parameters of the dynamic
`
`color variation program that affect the radiation generated by the light sources upon
`
`execution of the program.
`
`30
`
`For example, a particular illumination program may be designed such that, when
`
`executed, the radiation output from one or more light sources is varied at some
`
`predetermined rate to transition between a number of different colors in succession.
`
`
`
`Page 31 of 83
`
`

`
`- 10-
`
`Such illumination programs generally may be referred to as dynamic variable color
`
`illumination programs, and an example of such an illumination program is a "color
`
`wash" program. According to one embodiment of the invention, upon selection of a
`
`particular dynamic variable color illumination program, a color variation speed of the
`
`5
`
`program is noticeably increased from the predetermined rate for a short time period (e.g.,
`
`1 to 1 0 seconds) so that a user may recognize that the program has been selected.
`
`Thereafter, the color variation speed of the program is automatically decreased to the
`
`predetermined rate at which the program is intended to run.
`
`Another embodiment of the invention is directed to generating variable color
`
`I o
`
`radiation in a
