Abstract
A lighting apparatus comprises: a plurality of light source units comprising at least three light source units, wherein the light source units emit lights having different color temperatures from each other and different color coordinates from each other; a sensor sensing each of the light quantities of the R (red) component, G (green) component and B (blue) component of light mixed with lights emitted from a plurality of the light source units; a memory having a standard color coordinate located within an area formed by the color coordinates of the light output from the light source units; and a controller controlling light quantities of the light source units in such a manner as to reduce an error value between the standard color coordinate and a comparative color coordinate.
