Abstract:
A lighting apparatus disclosed in an embodiment comprises: a circuit board; a light-emitting module arranged on the circuit board and comprising a light source part having first to third light source parts emitting red, green and blue light; a control unit for providing current control signals to the first to third light source parts; a driver for controlling the current in the first to third light source parts by means of the control unit; and a memory unit having compensation data storing input current strength values for the first to third light source parts so that same emit white light having a previously configured correlated color temperature (CCT). The first, second and third light source parts comprise a plurality of first, second and third light-emitting elements for emitting red, green and blue light. The control unit controls the current in the first to third light source parts by means of the input current strength value corresponding to the compensation data so as to control the white light discharged from the light-emitting module is emitted as white light meeting the CCT criterion.
