摘要： A light source and an illumination device including the light source are provided. By adjusting peak wavelengths, peak intensities and color coordinates of blue light, red light and green light in the illumination light emitted by the light source to preset ranges, the illumination light emitted by the light source has a specific spectral distribution. In another embodiment, a specific light color is achieved by a specific phosphor ratio. Not only the color theory is considered for the evaluation of the lighting effect, but also the influence of the spectrum on the actual lighting effect is considered. At the same time, the influence of the luminescent material on the spectrum is considered. Thus, a light source having a high comfort, a high preference, a high color rendering index, and a high color gamut index is obtained, and the light source has a similar effect to the sunlight.

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.
