Abstract
A light source system and a projection system include a first laser array generating a red laser light; a second laser array generating a blue laser light; a beam-splitting plate located on a light path of the first and second laser arrays, for directing some of the red laser light and some of the blue laser light to a wavelength conversion device and directing some of the blue laser light to a light scattering device. The wavelength conversion device has wavelength conversion materials for receiving the blue laser light and producing a converted light, and for receiving and scattering the red laser light to form a first red light. The light scattering device has a scattering material for scattering the blue laser light to form a blue light. A light combining device forms a combined light from the converted light, the first red light and the blue light.
