Abstract
To provide a phosphor wheel capable of restraining vibration caused by a driving unit for rotatably driving a wheel and reducing noise in a high frequency band. The phosphor wheel includes: a wheel substrate that has a surface on which a fluorescent material is provided; a driving unit that rotates the wheel substrate; a support portion that supports the driving unit and is fixed to a housing; and a buffer member that is provided to fill a space between the support portion and a part of the housing.
Claims6
A phosphor wheel, comprising:
- a wheel substrate that has a surface on which a fluorescent material is provided;
- a driving unit that rotates the wheel substrate;
- a support portion that supports the driving unit and is fixed to a housing;
- and
- a buffer member that is provided to fill a space between the support portion and a part of the housing.
2 more elements
A light source unit, comprising:
- a light source;
- and
- a phosphor wheel that includes a fluorescent material that, when the fluorescent material is irradiated with light emitted from the light source, emits fluorescence emission light in a different wavelength region,
- wherein the phosphor wheel includes
- a wheel substrate that has a surface on which the fluorescent material is provided,
- a driving unit that rotates the wheel substrate,
- a support portion that supports the driving unit and is fixed to a housing, and
- a buffer member that is provided to fill a space between the support portion and a part of the housing.
5 more elements
An image display device, comprising:
- a light source unit that includes a light source and a phosphor wheel including a fluorescent material that, when the fluorescent material is irradiated with light emitted from the light source, emits fluorescence emission light in a different wavelength region;
- and
- an optical system that projects an image formed on the basis of a luminous flux emitted from the light source unit onto a plane of projection,
- wherein the phosphor wheel of the light source unit includes
- a wheel substrate that has a surface on which a fluorescent material is provided,
- a driving unit that rotates the wheel substrate,
- a support portion that supports the driving unit and is fixed to a housing, and
- a buffer member that is provided to fill a space between the support portion and a part of the housing.
