A lighting apparatus including a controller and an LED luminaire to implement a color temperature from a minimum of 3,000K or less to a maximum of 5,000K or more, the LED luminaire including at least one first light emitter, at least one second light emitter, and at least one third light emitter, in which a triangle region defined by color coordinates of the light emitters includes at least a region on a Planckian locus, and the maximum and minimum color temperatures in the triangle region are 5,000K or more, and 3,000K or less, respectively, and in the CIE-1931 coordinate system, the color coordinates of the first light emitter is closer to 5,000K than those of the second and third light emitters, and the color coordinates of the third light emitter is closer to 3,000K than those of the first and second light emitters.

Lighting apparatus and lighting system including the same

A lighting apparatus including a controller, an LED driver, and an LED luminaire, in which the LED luminaire implements a color temperature from a minimum color temperature of 3,000K or less to a maximum color temperature of 5,000K or more, and the controller controls the LED driver to change the color temperature of the LED luminaire corresponding to change in color temperature of sunlight.
