Abstract
A light source apparatus includes a light-emitting module and a control unit. The light-emitting module is for providing a light. The control unit switches the light emitted from the light-emitting module between a first light and a second light, wherein the circadian stimulus value (CS/P value) of the second light is less than CS/P value of the first light, and the color temperatures of the second light and the first light are substantially the same as each other.
