Light source module and lighting device including the same

A light source module, comprising:

• a first luminous element and a package part covering the first luminous element,
• wherein the first luminous element emits first color light with a peak wavelength of 435˜465 nm;
• wherein the package part comprises:
• a first additional illuminant, arranged to receive part of light emitted by the first luminous element and convert the part of light into second color light with a peak wavelength of 485˜515 nm,
• a second additional illuminant, arranged to receive part of light emitted by the first luminous element and convert the part of light into third color light with a peak wavelength of 520˜580 nm, and
• a third additional illuminant, arranged to receive part of light emitted by the first luminous element and convert the part of light into fourth color light with a peak wavelength of 615˜655 nm;
• wherein the first color light, the second color light, the third color light, and the fourth color light are mixed to form emitted light of the light source module, and the emitted light is neutral white light in CIE1931 color space, and the emitted light is within an interval surrounded by points with a correlated color temperature of 5000±350K and a distance from blackbody locus of duv=−0.006˜0.006.
