1. A method for correcting a lighting device, comprising:
- sensing light emitted from the lighting device when the lighting device is driven and generating sensing data including RGB values corresponding to the sensed light;
converting the sensing data into measured color coordinate values corresponding to color coordinates;
calculating differences between the measured color coordinate values corresponding to the sensing data and reference color coordinate values used when the lighting device is driven; and
correcting the reference color coordinate values on the basis of the calculated differences.

Abstract
Light emitted from a lighting device including a white LED and RGB LEDs is sensed when the lighting device is driven based on a predetermined reference value, sensed data is converted into values corresponding to color coordinates, and a difference between the value and a reference value is calculated. It is determined whether or not the lighting device is corrected on the basis of the calculated difference, and the lighting device is selectively corrected depending on the determination result.
