Claim:
1. A method of automatically calibrating a luminaire including at least one light emitting diode (LED) engine, the LED engine including a plurality of LEDs and a controller for driving the at least one LED engine, the method comprising: acquiring an image of light emitted from each LED of the LED engine; first determining whether each LED has a predetermined intensity for a color of the LED; first adjusting each LED that does not have the predetermined intensity to have the predetermined intensity for the color of the LED; measuring, by a spectrometer, a color spectrum of a combined light of the LED engine, the color spectrum including a plurality of measured color spectrums; second determining whether a variation exists between each of the plurality of measured color spectrums and a predetermined color spectrum of a control data unit; second adjusting at least one LED to correct any variation; third determining at least one of a group consisting of a total area of a color spectrum for each color, a color coordinate, a correlated color temperature (CCT), a color rendering index (CRI) value, a lumen output value, a gamut value, an intensity of each color in a specific wavelength range, and a percentage of spectral content in the specific wavelength range for each color; fourth determining whether a variation exists between the at least one of a group consisting of a total area of a color spectrum for each color, a color coordinate, a correlated color temperature (CCT), a color rendering index (CRI) value, a lumen output value, a gamut value, an intensity of each color in a specific wavelength range, and a percentage of spectral content in the specific wavelength range for each color and corresponding control data of a control data unit; and third adjusting at least one LED to correct any variation.
