Light emitting diode (LED) lighting system providing precise color control

A lighting system, comprising:

• a lighting apparatus comprising:
• a white light emitting diode (LED) and a red-green-blue (RGB) LED disposed on a mounting and at least partially enclosed by a housing, the RGB LED capable of producing red, green and blue components of light;
• a first LED driver to control current to the white LED;
• a second LED driver to control current to the RGB LED, the second LED driver comprising at least one 10-bit register that receives data for at least one component of the light emitted by the RGB LED, wherein the received data comprises a value representing a change of color and intensity from a value representing a current color and intensity of at least the RGB LED for a particular color of the RGB LED;
• and
• a microcontroller electrically connected to the first and second LED drivers;
• and
• the lighting system further comprising:
• a system controller including a memory to store preset lighting programs.

A method for providing wash lighting, the method comprising:

• emitting a current color and intensity from a white light emitting diode (LED) and from a red-green-blue (RGB) LED;
• receiving data comprising a value representing a change of color and intensity from a value representing the current color and intensity of at least the RGB LED for a particular color of the RGB LED;
• and
• emitting white light that is on the Planckian locus in the International Commission on Illumination (CIE) 1931 chromaticity diagram.
