WAVELENGTH CONVERSION ELEMENT AND LIGHT EMITTING DEVICE

WIPO Patent Application WO/2017/056470

A1

Provided is a wavelength conversion element (1) provided with: a support member (2) provided with a support surface (2a); and a wave conversion unit (4) disposed above the support surface (2a). The wave conversion unit (4) includes a plurality of first phosphor particles (4a) which absorb an excitation light (82) to generate fluorescence (second emitted light (91)), and a transparent bonding material (4b) for bonding the plurality of first phosphor particles (4a), and is provided with a joining surface (7) positioned on the support surface (2a) side and an incident surface (6) which faces the joining surface (7) and which the excitation light enters. The excitation light (82) and the fluorescence are emitted from the incident surface (6), the wavelength conversion unit (4) is provided with a plurality of protruding sections (5a), at least some of the plurality of protruding sections (5a) are disposed on the incident surface (6), and at the top of each of the plurality of protruding sections (5a), some of the plurality of first phosphor particles (4a) are exposed.
