Abstract
A light source module includes a blue light generation portion, a cyan light generation portion, a yellow-green light generation portion and a red light generation portion. The red light generation portion includes a first additional light emitter and a second additional light emitter, the first additional light emitter emits a light having a main emission peak in the red light wave band, the second additional light emitter emits a light having a secondary emission peak in the red light wave band, and a spectral intensity of the secondary emission peak is 30.0%-80.0% of a spectral intensity of the main emission peak. An emitted light of the light source module is a white light with a color temperature of 3000K˜6000K, and in a CIE1931 color space, a distance between the emitted light and a blackbody locus BBL is duv=−0.007-0.007.
