Lighting Control System and Method

A recessed lighting fixture, comprising:

• first and second light sources each comprising a light emitting diode;
• the first light source being operable to generate light having a cool white color temperature greater than or equal to 2700 degrees Kelvin;
• the second light source being operable to generate light having a warm white color temperature less than or equal to 2700 degrees Kelvin, and between about 500 and 4000 degrees Kelvin less than the cool white color;
• a controller coupled to the first and second light sources;
• the controller being operable to receive a color control signal from a color control providing a variable color control signal;
• throughout a first range of the color control signal, the controller being operable to adjust outputs of the first and second light sources, as a function of the color control signal, continuously and in an opposite manner, to smoothly vary the perceived color output of the recessed lighting fixture between the cool white color and the warm white color.

• the first light source being operable to generate light having a cool white color temperature greater than or equal to 2700 degrees Kelvin;
• the second light source being operable to generate light having a warm white color temperature less than or equal to 2200 degrees Kelvin;
• a color control comprising a dimmer providing a variable color control signal to adjust a perceived color output of the lighting system;
• a controller coupled to the color control to receive the color control signal, and coupled to the first and second light sources;
• and
• throughout a first range of the color control signal, the controller being operable to adjust outputs of the first and second light sources in a continuous manner, as a function of the color control signal, to smoothly vary the perceived color output of the lighting system between the cool white color and the warm white color.

A lighting system, comprising:

• first and second light sources each comprising a light emitting diode;
• the first light source being operable to generate light of a first color;
• the second light source being operable to generate light of a second color, different than the first color;
• a color control operable to generate a variable voltage color control signal to adjust a perceived color output of the lighting system;
• a controller coupled to the color control to receive the color control signal, and coupled to the first and second light sources;
• the color control signal having a first range defined by first and second states;
• at the first state of the color control signal, the perceived color output of the lighting system being the first color, and at the second state of the color control signal, the perceived color output of the lighting system being the second color;
• and
• throughout the first range of the color control signal, the controller being operable to adjust outputs of the first and second light sources in a continuous manner, as a function of the color control signal, to smoothly vary the perceived color output of the lighting system between the first color and the second color.
