[0002] With the rapid advancement of lighting technology, people's demands for lighting are becoming increasingly sophisticated and complex. On the one hand, lighting products need to have good color rendering properties, meaning the light needs to have a high color rendering index while also having low color tolerance. On the other hand, because light can affect human physiological functions and behavior, the requirements for the rhythmic effect of lighting are also becoming increasingly stringent.

[0003] In existing technologies, color correction is mostly achieved through CW dimming or RGB dimming. While CW dimming can achieve a high color rendering index (CRI), the CRI decreases in mixed colors, color tolerance increases, and it cannot display a wide range of colors. Although RGB dimming can achieve variations in white light along the blackbody radiation curve and can display a wide range of colors, it cannot meet the basic CRI requirements.

[0028] Specifically, the peak wavelength of the pale blue light from the second emitting unit refers to the wavelength of the peak with the highest luminous intensity in its light source radiation spectrum, and correspondingly, the full width at half maximum (FWHM) is the FWHM of that peak. For example, the peak wavelength of the pale blue light is 435nm, 450nm, 465nm, 480nm, 485nm, 490nm, or 495nm, but is not limited to these. Preferably, it is 440nm~450nm, 440nm~460nm, 450nm~480nm, or 470nm~480nm, but is not limited to these.
