LIGHT SOURCE DEVICE, ILLUMINATION DEVICE, AND VEHICLE LAMP
Document Type and Number:
WIPO Patent Application WO/2017/090675
Kind Code:
A1
Abstract:
A light source device (1000) is provided with a light source (2), a wavelength conversion member (4), and a retroreflective optical member (9). The light source (2) emits excitation light (50). When a first region (8) is irradiated with the excitation light (50), the wavelength conversion member (4) emits, from the first region (8), converted light (51) having a wavelength different from that of the excitation light (50). The retroreflective optical member (9) reflects the converted light (51) toward the first region (8). The first region (8) is a part of the wavelength conversion member (4).
