Automated Calibration of LED Luminaires Based on Color Coordinates

摘要

Disclosed is 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 comprises 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, and second adjusting at least one LED to correct variation.

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; and second adjusting at least one LED to correct any variation.
