Light source module and projector

Abstract

A light source module includes: a light source section that emits excitation light; a wavelength conversion section that outputs first light and second light that are in mutually different wavelength bands; a fluorescent substance region that absorbs the excitation light and outputs the first light together with the second light, the first light being fluorescent light in a different wavelength band from the excitation light, the fluorescent substance region being provided in the wavelength conversion section; a reflection region that outputs the excitation light as the second light in a different angular distribution from the second light output from the fluorescent substance region, the reflection region being provided in the wavelength conversion section; and a region-division wavelength selector including a first region and a second region, the first region transmitting the first light and the second light, the second region reflecting or absorbing the second light selectively.
