Document Type and Number:
Japanese Patent JP7261910
Kind Code:
B2
Abstract:
A light source system (200), comprising a first light source (10), a first wavelength conversion device (20), a second wavelength conversion device (30), a light path conversion element (40), and a light combining unit (50). The light path conversion element (40) is configured to make an excitation light emitted by the first light source (10) irradiate the first wavelength conversion device (20) and the second wavelength conversion device (30) in turn, so as to correspondingly excite and generate a first excited light and a second excited light. The light combining unit (50) is configured to combine the first excited light and the second excited light. The first wavelength conversion device (20) and the second wavelength conversion device (30) share the first light source (10), thus making the system compact, easy to cool, and inexpensive. A projector, comprising the light source system (200).
