  • Phosphor wheel
    Patent number: 10613317
    Abstract: There is provided a phosphor wheel which can reduce or prevent misalignment and clipping of a diffuser plate. A phosphor wheel includes a wheel plate which has an opening extending from one surface to the other surface and is to be used in a rotating state, and a transmissive member which is disposed inside the opening. The transmissive member is in contact with an edge of the opening of the wheel plate at a plurality of points including two points of an outer periphery part on an outer side in a rotation radius direction of the wheel plate to be supported. Accordingly, as compared to the case where the outer periphery part of the transmissive member is in contact with the edge of the opening at one point, the transmissive member is held more stably, and misalignment and clipping can be reduced or prevented.
