RGB spa light using light emitting diodes

A lighting system, comprising:

• a central controller for generating control signals;
• one or more lighting subsystems each of which accepts said control signals from said controller, each of said subsystems comprising;
• first and second lighting units connected in series, each of which comprises a plurality of light emitting diodes (LEDs) each being a different type and emitting different colors of light, each of said lighting units having a power lead and a respective lead from each of its said LEDs and each said lighting units comprising similar types of LEDs emitting the similar colors of light;
• electronic circuitry, some of which is arranged between said first and second serially connected lighting units, said electronic circuitry accepting said controller control signals corresponding to power and each of said type of said LEDs, said control signals and electronic circuitry arranged to cause one or more pairs of corresponding LEDs types in said lighting units to emit light.

A lighting subsystem, comprising:

• control lines each of which accepts one of a plurality of control signals from a controller;
• first and second lighting units connected in series, each of which comprises a plurality of light emitting diodes (LEDs) each being a different type and emitting different colors of light, each of said lighting units having a power lead and a respective lead from each of its said LEDs and each said lighting units comprising similar types of LEDs emitting at similar colors of light;
• and
• electronic circuitry, some of which is arranged between said first and second serially connected lighting units, said electronic circuitry accepting said control signals on said control lines, said control signals corresponding to power and each of said type of said LEDs, said control signals and electronic circuitry arranged to cause one or more pairs of corresponding LEDs types in said lighting units to emit light.

A system for illuminating a reservoir of water, comprising:

• a reservoir shell capable of holding water;
• one or more reservoir components extending through said reservoir shell;
• a central controller for generating control signals;
• one or more lighting subsystems each of which accepts said control signals from said controller, each of said subsystems comprising;
• first and second lighting units to provide light to said reservoir through at least one of said reservoir components, said lighting units connected in series, each of which comprises a plurality of light emitting diodes (LEDs) each being a different type and emitting different colors of light, each of said lighting units having a power lead and a respective lead from each of its said LEDs and each said lighting units comprising similar types of LEDs emitting at similar colors of light;
• and
• electronic circuitry, some of which is arranged between said first and second serially connected lighting units, said electronic circuitry accepting said control signals on said control lines, said control signals corresponding to power and each of said type of said LEDs, said control signals and electronic circuitry arranged to cause one or more pairs of corresponding LEDs types in said LED units to emit light.
