Title:
LIGHT-SOURCE SYSTEM AND PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/028240
Kind Code:
A1
Abstract:
Provided is a light-source system (20), comprising an excitation light source (21), a first supplementary light source (22), a first light-guiding assembly (23), a wavelength conversion apparatus (24), and a second light-guiding assembly (25). The excitation light source (21) is used for emitting excitation light; the first supplementary light source (22) is used for emitting a first supplementary light. The first light-guiding assembly (23) is used for guiding the excitation light to the wavelength conversion apparatus (24). The wavelength conversion apparatus (24) is used for converting excitation light to excited light and emitting the excited light to the first light-guiding assembly (23). The first light-guiding assembly (23) is also used for guiding excited light, causing the excited light to shine toward the second light-guiding assembly (25). At least some of the components of the second light-guiding assembly (25) are arranged on the optical path following emission from the first light-guiding assembly. The second light-guiding assembly (25) is used for guiding one or both of the excited light and the first supplementary light, such that the first supplementary light and at least part of the excited light are emitted from the same emission channel. Also provided is a projection device.
