Abstract: A lighting device with physiological dimming and a dimming method for the same are provided. The lighting device includes a lighting unit with lighting modules, a light sensor, and a control circuit. According to a first illumination requirement and a light sensing value of the light sensor, the control circuit controls the lighting unit to output a first illumination light source that meets a first predetermined illuminance in a first time slot. According to a second illumination requirement and the light sensing value, the control circuit controls the lighting unit to output a second illumination light source that meets a second predetermined illuminance in a second time slot. According to the first and the second illumination requirements, the control circuit dynamically controls lighting from any one or a combination of the lighting modules, such that the lighting unit generates correspondingly the first and the second illumination light sources.

Abstract: A light source apparatus including a light-emitting module and a control unit is provided. The light-emitting module is configured to provide a light. The control unit is configured to make the light switched between a first light and a second light so that at least one of a blue-light hazard and a circadian stimulus value of the light is changed. A wavelength of a blue light main peak in a spectrum of the first light is different from a wavelength of a blue light main peak in a spectrum of the second light.
