Abstract:
Disclosed herein is a lighting apparatus using white-light Light-Emitting Diodes (LEDs). The lighting apparatus includes white-light LEDs, first LEDs, second LEDs, a substrate, a driving unit, and wires. The white-light LEDs emit light having a first peak value in a wavelength range of about 440 to 460 nm and a second peak value in a wavelength range of about 520 to 600 nm as a main light source. The first LEDs emit light having a third peak value in a wavelength range of about 610 to 625 nm as an auxiliary light source. The second LEDs emit light having a fourth peak value in a wavelength range of about 492 to 500 nm as an auxiliary light source. The substrate allows the LEDs to be disposed thereon. The driving unit drives the LEDs. The wires connect the substrate to the driving unit.
