Document Type and Number:
WIPO Patent Application WO/2019/134262
Kind Code:
A1
Abstract:
A light source apparatus (1000), comprising: an excitation light source (10), a color wheel (14), a light optimization component, a light guide assembly (18), and a light processing and outputting component (16). The color wheel (14) comprises a conversion area used for receiving excitation light and for generating excited light, and a non-conversion area used for receiving excitation light and outputting excitation light. The light optimization component is used for optimizing the excited light. The light guide assembly (18) is used for guiding the excitation light and the excited light that have undergone the optimization by means of the light optimization component to exit through a same output channel. The light processing and outputting component (16) is used for processing and outputting the excitation light and excited light exiting from the output channel.
