Title:
FLUORESCENT BODY DEVICE AND LIGHT SOURCE MODULE
Document Type and Number:
WIPO Patent Application WO/2023/229022
Kind Code:
A1
Abstract:
A fluorescent body device (1) comprises: a substrate member (10); and a wavelength conversion member (20) provided on the substrate member (10) and having a fluorescent section (21) and a light reflection section (22). The fluorescent section (21) has a light input surface (211) and a light output surface (212). The light reflection section (22) is provided so as to surround the fluorescent section (21) when observed from the direction of the light output surface (212). The main component of the fluorescent section (21) is a YAG fluorescent ceramic containing Ce3+. The main component of the light reflection section (22) is a light reflective ceramic. The Ce3+ concentration of the YAG fluorescent ceramic is 0.005-0.02%, and the thickness of the YAG fluorescent ceramic is 350-820 μm.
