Abstract:
An object of the present invention is to improve the efficiency of heat dissipation from a phosphor wheel while suppressing the air resistance and noise of the phosphor wheel during the driving of a light source apparatus. A phosphor wheel ( 100 ) according to the present invention includes: a disc-like substrate ( 120 ); a phosphor layer ( 130 ) formed on the substrate; and a plurality of heat dissipation fins ( 154 a,  154 b , and  154 c ) overlapping with each other when viewed in a direction orthogonal to a surface of the substrate.

Claim (Index 20):
A projection-type display apparatus, comprising:\n a light source apparatus; a light modulation and synthesis system configured to modulate and synthesize incident light; an illumination optical system configured to guide light emitted from the light source apparatus to the light modulation and synthesis system; and a projection optical system configured to project an image emitted from the light modulation and synthesis system, wherein the light source apparatus includes: a solid state light source configured to emit excitation light having a first wavelength, a phosphor wheel including; a substrate, a phosphor layer on the substrate and the phosphor layer configured to excite by the excitation light and emit light having a second wavelength different from the first wavelength and to transmit a part of the excitation light, and a plurality of heat dissipation fins, wherein a first fin of the plurality of heat dissipation fins overlaps with a second fin of the plurality of heat dissipation fins when viewed in a direction orthogonal to a surface of the substrate, and a motor configured to rotationally drive the phosphor wheel in a plane parallel to the surface of the substrate.
