摘要： A light-source device includes an excitation light source to emit first color light; an optical member having a reflecting surface to reflect the first color light; a wavelength conversion unit including a wavelength conversion member on which the first color light reflected by the optical member is incident, the wavelength conversion member to convert at least part of the first color light into second color light having a wavelength different from a wavelength of the first color light and emit the second color light; and a light condensing element to condense the first color light emitted from the wavelength conversion unit. A straight line including a first optical path from a center of a flux of light rays emitted from the excitation light source, to the center of the first color light on the reflecting surface does not intersect with a light flux condensed by the light condensing element.

摘要： A display device, a display system, and a mobile object. The display device includes an image forming unit through which image light exits, an imaging optical system having a reflection plane and configured to form an image by reflecting the image light on the reflection plane, and a housing accommodating the image forming unit and the imaging optical system. The housing has a transmissive area through which the image light reflected by the imaging optical system passes through, and an inclination of the reflection plane is changed to reduce a project area of the reflection plane. The project area is projected to outside of the housing through the transmissive area. The display system includes the display device, and a reflector configured to reflect the image light reflected by the imaging optical system. The mobile object includes the display system, and the reflector is a front windshield.
