Claim Text:
1. A lighting apparatus comprising: a plurality of light emitting diodes (LEDs) consisting of: wherein each of the first LEDs is configured to emit light having a third peak value in a wavelength range of about 610 to 625 nm and functions as an auxiliary light source to the white LEDs, and wherein each of the second LEDs is configured to emit light having a fourth peak value in a wavelength range of about 492 to 500 nm and functions as an auxiliary light source to the white LEDs; a substrate for allowing the white LEDs, the first LEDs, and the second LEDs to be disposed thereon; a driving unit for driving the white LEDs, the first LEDs, and the second LEDs; and wires for connecting the substrate to the driving unit, wherein the first LEDs improve the color rendering of the white LEDs by increasing a color rendering index (CRI) of the plurality of LEDs to be greater than 90.
