Abstract:
The present invention relates to a white light emitting diode (LED) package that includes a blue LED chip to emit blue light; a yellow phosphor excited by the blue light and emit yellow light, the yellow light to produce a primary white light in combination with the blue light; a red LED chip to emit red light, the red light to adjust the primary white light into secondary white light of an incandescent color; and a package member comprising at least a partial transmissive part covering the blue LED chip, the red LED chip, and the yellow phosphor. The primary white light falls in a region of (0.413, 0.502), (0.335, 0.376), (0.37, 0.371), and (0.439, 0.48) based on a CIE color coordinate standard.
