Title: LIGHT SOURCE APPARATUS AND PROJECTION SYSTEM
Abstract:
Disclosed is a light source apparatus, comprising a first light source (201), a fly-eye lens pair (202), a light guide system and a wavelength conversion apparatus (206), wherein the first light source (201) emits first excitation light (L1) which enters, after being homogenized by the fly-eye lens pair (202), the light guide system; the light guide system guides the first excitation light (L1) to the wavelength conversion apparatus (206); the wavelength conversion apparatus (206) comprises a wavelength conversion segment and a reflection segment; the wavelength conversion segment absorbs the first excitation light (L1) and emits excited light (L3); the first excitation light (L1) obliquely enters the reflection segment and is reflected to form second excitation light (L2); the light guide system is also used for collecting the excited light (L3) and the second excitation light (L2) and guiding the excited light (L3) and the second excitation light (L2) to exit along an emergent light channel; the light guide system comprises a light path correction assembly (209) that is located on a light path of the second excitation light (L2), reflects the second excitation light (L2) and enables a primary light axis of the reflected second excitation light (L2) to coincide with a primary light axis of the excited light (L3); the fly-eye lens pair (202) comprises first and second lens arrays arranged in the direction of the first excitation light (L1); and various lens units composing the first lens array are imaged on a surface of the wavelength conversion apparatus (206) in an overlapping manner.
