1. A lighting device comprising:
a plurality of light emitting diode (LED) chips that emit light; and a plurality of LED modules having a printed circuit board (PCB) which supports and drives the plurality of LED chips; wherein the plurality of LED chips are divided into a plurality of blocks which are separated from each other through printing circuit patterns in a circuit manner so as to be independently turned on/off, and wherein the plurality of LED modules include a plurality of white LED chips, the white LED chips include blue LEDs, red phosphors and green phosphors, color coordinates of red light emitted from the red phosphors are positioned within a region surrounded by four vertexes of (0.6448, 0.4544), (0.8079, 0.2920), (0.6427, 0.2905) and (0.4794, 0.4633) on the basis of the CIE 1931 color coordinate system, and color coordinates of green light emitted from the green phosphors are positioned within a region surrounded by four vertexes of (0.1270, 0.8037), (0.4117, 0.5861), (0.4197, 0.5316), and (0.2555, 0.5030). |
