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.
