Abstract
A light source apparatus according to an embodiment of the present technology includes a wheel, a rotation drive unit, and a first adhesive material. The wheel includes a light-emitting body that emits visible light by being excited. The rotation drive unit includes a support surface including a reference surface that comes into contact with the wheel and a non-contact surface that is set apart from the wheel, and causes the wheel supported by the support surface to rotate. The first adhesive material is filled in at least a part of a gap between the non-contact surface and the wheel.
Claims15
A light source apparatus, comprising:
- a wheel including a light-emitting body that emits visible light by being excited;
- a rotation drive unit that includes a support surface including a reference surface that comes into contact with the wheel and a non-contact surface that is set apart from the wheel, and causes the wheel supported by the support surface to rotate;
- and
- a first adhesive material filled in at least a part of a gap between the non-contact surface and the wheel.
An image display apparatus, comprising:
- (a) a light source apparatus including
- a wheel including a light-emitting body that emits visible light by being excited,
- a rotation drive unit that includes a support surface including a reference surface that comes into contact with the wheel and a non-contact surface that is set apart from the wheel, and causes the wheel supported by the support surface to rotate,
- a first adhesive material filled in at least a part of a gap between the non-contact surface and the wheel, and
- a light-emitting surface that emits light including the visible light from the light-emitting body;
- (b) an image generation system including
- an image generation device that generates an image on a basis of irradiated light, and
- an illumination optical system that irradiates light from the light source apparatus onto the image generation device;
- and
- (c) a projection system that projects the image generated by the image generation device.
An optical unit, comprising:
- a wheel including a light-emitting body that emits visible light by being excited;
- a rotation drive unit that includes a support surface including a reference surface that comes into contact with the wheel and a non-contact surface that is set apart from the wheel, and causes the wheel supported by the support surface to rotate;
- and
- a first adhesive material filled in at least a part of a gap between the non-contact surface and the wheel.
