With the continuous development and progress of lamps, the lamps are no longer used for illumination, and people begin to pay more attention to the influence of the illumination lamps on eyes. Because human eyes are adapted to the natural light environment in the long-term evolution process, the stimulation to the human eyes is lower in the natural light environment, the comfort of the human eyes is better, and the human eyes also have a certain protection effect on the eyesight.

The four light-emitting elements are, for example, a first light-emitting element 21, a second light-emitting element 22, a third light-emitting element 23, and a fourth light-emitting element 24.

The spectrum of the first light emitting element 21 is a first segmented spectrum, the spectrum of the second light emitting element 22 is a second segmented spectrum, the spectrum of the third light emitting element 23 is a third segmented spectrum, and the spectrum of the fourth light emitting element 24 is a fourth segmented spectrum.

The first segmented spectrum, the second segmented spectrum, the third segmented spectrum and the fourth segmented spectrum are sequentially connected to form a spectrum of 700 nm-785 nm. That is, four kinds of light emitting elements are used, the spectra of the four kinds of light emitting elements can correspond to four parts in the 700nm to 785nm band, and the second light emitting element 20 can emit the spectra in the 700nm to 785nm band by combining the four kinds of light emitting elements. For example, 700nm to 785nm may be divided into four bands, and the spectra of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 may be made to correspond to the four bands. In other words, the four light emitting elements are respectively and correspondingly supplemented in a segmented manner, and finally, the supplement of the wave band of 700nm to 785nm is realized, so that the implementation is easier, and the design difficulty and the cost of the second light emitting element 20 are reduced, thereby reducing the implementation difficulty and the cost of the whole light source 100.
