LIGHT SOURCE SYSTEM, AND PROJECTION SYSTEM AND METHOD

摘要

A light source system including: a light source device emitting excitation light; an light output device receiving the excitation light and converting it into converted light, wherein the light output device includes at least two different wavelength conversion materials, the converted light of at least one wavelength conversion material being a multi-color light; a light splitting and combining device splitting the multi-color light into a first and a second color light propagating respectively along a first and a second optical channel, wherein the first and second color lights have different wave spectrum coverage ranges; and a first and a second light modulation device respectively modulating the light propagating over the first and second optical channels, wherein the light of three primary colours can be allocated to two DMDs for processing. This results in improved colour gamut of the light source and the light efficiency and reliability of the system.

1. A light source system, comprising:
a light source device, including least one group of excitation light sources generating an excitation light; a light output device, which receives the excitation light and converts the excitation light to generate a converted light for output, wherein the light output device includes at least two different wavelength conversion materials, and wherein at least one of the wavelength conversion materials generates a converted light that is a multi-color light; a light separation and combination device, which separates the multi-color light into a first light of a first wavelength range travelling along a first light path and a second light of a second wavelength range travelling along a second light path, wherein the first wavelength range and the second wavelength range are different, and wherein a combined light of all converted lights is a white light; a first light modulation device, which modulates light that travels along the first light path; and a second light modulation device, which modulates light that travels along the second light path.
