Title:
LIGHT SOURCE DEVICE AND PROJECTOR
Document Type and Number:
Japanese Patent JP2022142101
Kind Code:
A
Abstract:
To provide a light source device and projector that can change a position where light is incident in a wavelength conversion element.SOLUTION: A light source device 4A includes: a light source 421 that emits light having a first wavelength band; a wavelength conversion element 66 that converts the light having the first wavelength band into light having a second wavelength band different from the first wavelength band; a substrate 67 supporting the wavelength conversion element; a light source housing 41A to which the light source and the substrate are fixed; a first reflection element 61 that guides the light having the first wavelength band emitted from the light source to the wavelength conversion element; and a driving element 63 that changes a position where the light having the first wavelength band is incident in the wavelength conversion element by moving the first reflection element to the light source housing.SELECTED DRAWING: Figure 2
