摘要： A light source module and a lighting device including the light source module are provided. The light source module includes a first luminous element and a package part covering the first luminous element. The package part includes a first additional illuminant, a second additional illuminant, and a third additional illuminant. The light emitted by the illuminants is mixed to form positive white light which serves as the emitted light of the light source module. The light source module provided by the present disclosure provides an LED positive white light (5000K) light source with high light efficiency, high CS value and high color rendering property by controlling the proportion of luminous energy in different wavelength regions in the total luminous energy. Under the same illumination, the spectrum with high CS value is especially suitable for people to concentrate on learning and working.
