Abstract: A wheel apparatus includes a substrate rotatable around a rotation axis, and a plurality of optical elements respectively formed in a plurality of regions different from each other around the rotation axis on the substrate and having wavelength characteristics different from each other. The regions of the plurality of optical elements are adjacent to each other via boundary lines including linear sections. The linear sections of the boundary lines intersect with respective straight lines along the radius of the substrate at the same intersection angle greater than 0 degrees and less than 90 degrees.

Abstract: A light source device includes a light source element that emits light source light in a first wavelength region, a selective reflection element that separates the light source light into first light and second light, a first light direction conversion element that reflects the first light guided in a first direction from the selective reflection element in a second direction, and a wavelength conversion element that converts the first light into third light in a second wavelength region. The first light direction conversion element reflects the third light in a third direction opposite to the first direction. The selective reflection element transmits the third light reflected by the first light direction conversion element. The selective reflection element guides the second light and the third light in the third direction. The light source element emits the light source light in a direction different from the second direction.

Abstract: A phosphor wheel according to the present disclosure includes: a first substrate having a first main surface and a second main surface opposite to the first main surface, the first substrate including a metal material; a phosphor ring provided on the first main surface of the first substrate; a second substrate having a third main surface and a fourth main surface being opposite to the third main surface, the second substrate including a metal material; a plurality of heat dissipation fins disposed on the fourth main surface of the second substrate; and a motor mounted on the first substrate. The second main surface of the first substrate and the third main surface of the second substrate are joined by brazing. The motor is mounted on the first substrate with a gap interposed between the motor and the second substrate.
