Abstract
A rotor unit includes a rotor including a substrate and a wavelength conversion region, and a driving unit. The substrate includes an outer edge and is configured such that a substrate material is continuously provided from a center to the outer edge. The wavelength conversion region is provided on the substrate and receives light having a first wavelength region and emits light having a second wavelength region different from the first wavelength region. The driving unit rotates the rotor.
Claims11
A rotor unit, comprising:
- a rotor including
- a substrate that includes an outer edge and is configured such that a substrate material is continuously provided from a center to the outer edge, and
- a wavelength conversion region that is provided on the substrate and receives light having a first wavelength region and emits light having a second wavelength region different from the first wavelength region;
- a driving unit that rotates the rotor;
- a fixing member that fixes a rotational shaft of the driving unit to the substrate, the fixing member including a surface and three or more seat surfaces provided on the surface so as to project above the surface;
- and
- an adhesive material interposed between the substrate and the surface,
- wherein a bottom surface of the substrate is held in direct contact with a planar top surface of the three or more seat surfaces such that at least an area without adhesive material is interposed between the planar top surface of the three or more seat surfaces and the bottom surface of the substrate.

A projector, comprising:
- a light source;
- a rotor including
- a substrate that includes an outer circumferential edge and is configured such that a substrate material is continuously provided from a center to the outer circumferential edge, and
- a wavelength conversion region that is provided on the substrate and receives light having a first wavelength region from the light source and emits light having a second wavelength region different from the first wavelength region;
- a driving unit that rotates the rotor;
- a fixing member that fixes a rotational shaft of the driving unit to the substrate, the fixing member including a surface and three or more seat surfaces provided on the surface so as to project above the surface;
- an adhesive material interposed between the substrate and the surface;
- a light modulation element that modulates light emitted from the wavelength conversion region of the rotor;
- and
- a projection optical system that projects modulation light obtained by modulation of the light modulation element,
- wherein a bottom surface of the substrate is held in direct contact with a planar top surface of the three or more seat surfaces such that at least an area without adhesive material is interposed between the planar top surface of the three or more seat surfaces and the bottom surface of the substrate.
