Abstract:
The disclosure provides a wavelength conversion wheel including a substrate, a first wavelength conversion layer, and a second wavelength conversion layer. The substrate has a rotation central axis. The first wavelength conversion layer is disposed on the substrate and has a first end. The second wavelength conversion layer is disposed on the substrate and has a second end. The second end is closely adjacent to the first end. An edge of the first end and an edge of the second end are complementary in shape, and a boundary formed between the edge of the first end and the edge of the second end is not parallel to a radial direction of the substrate, wherein the radial direction is perpendicular to an extension direction of the rotation central axis. A projection apparatus using the wavelength conversion wheel is further provided.

Claim (Index 6):
A projection apparatus comprising: an excitation light source, a wavelength conversion wheel, a light valve, and a projection lens, the wavelength conversion wheel comprising a substrate, a first wavelength conversion layer, and a second wavelength conversion layer, wherein\n the substrate has a rotation central axis and is adapted to rotate about the rotation central axis, the excitation light source is configured to provide an excitation light beam, the wavelength conversion wheel is disposed on an optical path of the excitation light beam, wherein the first wavelength conversion layer is disposed on the substrate and has a first end, the second wavelength conversion layer is disposed on the substrate and has a second end, wherein the first wavelength conversion layer and the second wavelength conversion layer are configured to convert the excitation light beam into a conversion light beam, wherein the second end is closely adjacent to the first end, an edge of the first end and an edge of the second end are complementary in shape, and a boundary formed between the edge of the first end and the edge of the second end is not parallel to a radial direction of the substrate, wherein the radial direction is perpendicular to an extension direction of the rotation central axis, the light valve is disposed on a transmission path of the conversion light beam and receives the conversion light beam to form an image light beam, and the projection lens is disposed on a transmission path of the image light beam and receives the image light beam to form a projection light beam.
