AI Technical Summary
Technical Problem
Existing wavelength conversion components lack sufficient surface light sealing beyond the light incident and light exit surfaces, which affects the efficiency of light wavelength conversion.
Method used
By acid-treating the sintered body containing inorganic particles and phosphor particles, multiple recesses are formed on the light-reflecting surface. Combined with the reflective components covering the light-reflecting surface, the light-sealing performance is improved.
Benefits of technology
It enhances the light-sealing properties of the light-reflecting surface, reduces light leakage, and improves the wavelength conversion efficiency and the clarity of the boundaries of optical components.

Abstract
Provided is a wavelength conversion member manufacturing method and a wavelength conversion member including a sintered body having improved light-tightness of a surface other than a light incident surface and a light exit surface. A wavelength conversion member manufacturing method including a sintered body having a light incident surface, a light exit surface, and a light reflection surface different from the light incident surface and the light exit surface includes: a sintered body preparation step of preparing a sintered body including inorganic particle and phosphor particle; and a recess formation step of performing acid treatment on the sintered body to form a plurality of recesses in the light reflection surface of the sintered body.
