LIGHT SOURCE APPARATUS

摘要

This light source apparatus (2) is provided with a light-synthesizing element (70) and a phosphor element (40G). The light-synthesizing element (70) transmits a first excitation light and reflects a second excitation light. The phosphor element (40G) receives the first excitation light and the second excitation light and emits fluorescence. The emission angle of the first excitation light emitted from the light-synthesizing element (70) and the reflection angle of the second excitation light reflected by the light-synthesizing element (70) differ, causing the position (400a) on the phosphor element (40G) reached by the first excitation light that has been transmitted by the light-synthesizing element (70) to differ from the position (400b) on the phosphor element (40G) reached by the second excitation light reflected by the light-synthesizing element (70). This light source apparatus is capable of attenuating any increase of the number of components of an optical component, and suppressing local light saturation of a phosphor.
