1. A correlated color temperature (CCT) modulating method, comprising:

  • modulating a white light emitting diode (LED) light source to emit a first white light;

    modulating at least one LED light source to emit at least one broad-spectrum monochromatic light; and

    mixing the first white light and the broad-spectrum monochromatic light to produce a second white light, wherein a color rendering index (CRI) of the second white light is greater than a CRI of the first white light, and a color coordinate of the first white light are different from a color coordinate of the second white light.
