摘要： A light-source device includes an excitation light source, an optical member, and a wavelength converter. The excitation light source is configured to emit first color light. The optical member has a reflecting surface configured to reflect the first color light emitted from the excitation light source. The wavelength converter includes a wavelength conversion member on which the first color light reflected by the optical member is incident. The wavelength conversion member is configured 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. A center of the first color light on the reflecting surface of the optical member does not intersect with a light flux of the first color light emitted from the wavelength converter.

摘要： An HUD apparatus is configured to irradiate light for forming an image on a transmissive reflector provided in a movable body, and to display a virtual image in a display area to overlap the virtual image with scenery outside the movable body. A given distance range in the scenery from a reference point that is set in the movable body is included in the display area, and a difference between a first convergence angle to a target object (e.g., road surface) that is present in the given distance range and a second convergence angle to the virtual image displayed in the display area is at most one degree.
