Abstract
A light source system includes a first light source emitting first laser; a wavelength conversion device; a driver device driving the wavelength conversion device to move in such a manner that regions of the wavelength conversion device sequentially and periodically receive the first laser; a second light source emitting supplementary light consistent in color with light emitted by one primary color light region; a control device controlling on and off of the second light source, the control device controlling the second light source to be on in at least two of: every time period during which a primary color light region of a same color is receiving the first laser, every time period during which the mixed color light region is receiving the first laser, and some time periods during which a primary color light region of a different color is receiving the first laser.
