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.
