Abstract: A light source device includes: a light source to emit an excitation light beam having a first wavelength; a heat generation member to convert the first wavelength of the excitation light beam emitted from the light source into a light beam having a second wavelength different from the first wavelength; a substrate to which the heat generation member is attached; a motor to rotate the substrate; a bracket to hold the motor; a casing having an opening penetrating through the casing; and a cooling member connected to the bracket. The casing accommodates the light source, the heat generation member, the substrate, and the bracket. The cooling member cools the heat generation member via the bracket; and seals the opening.

Abstract: A projection optical device includes a projection lens unit, a projection optical element, an optical housing, a holder, and a mover. The projection lens unit holds a projection lens on which a projection image generated by an image generating device is incident. The projection optical element guides the projection image, which has passed through the projection lens, to a projection surface. The optical housing is attached with the image generating device. The holder is attached to the optical housing. The holder holds the projection lens unit and the projection optical element. The mover relatively moves the holder with respect to the optical housing in an incident direction in which the projection image is incident on the projection lens.

Abstract: An illumination optical system is provided that is configured to guide light emitted from a light source to an image generation unit that is arranged to be movable in a direction perpendicular to incoming light and is configured to generate an image by reflecting the incoming light. The illumination optical system includes a first lens that is arranged to be movable in a direction perpendicular to an optical axis of the first lens, a second lens that is arranged to be movable in a direction that changes a face-to-face distance between the first lens and the second lens, and a lens position control unit configured to displace the first lens and the second lens.
