The present invention relates to light-emitting diode lighting, and more particularly to a method and an apparatus for controlling color conversion in light-emitting diode lighting. The apparatus for controlling color conversion in light-emitting diode lighting according to the present invention may be configured to comprise: a light-emitting unit which includes a first light source emitting light in a first wavelength band, a second light source emitting light in a second wavelength band, and a third light source emitting light in a third wavelength band; a power unit which supplies power to drive the light-emitting unit; first, second, and third switches which are connected to the first, second, and third light sources of the light-emitting unit, respectively; a switch drive unit which controls the switches; and a control unit which has a predetermined control period, controls light-emitting times of the light sources, and performs controlling the switch drive unit so that reference points for the light-emitting times become points in a range of 30 to 70% of the control period. |
