Abrégé

A color wheel (100) and a projection system (200), relating to the technical field of optics. The color wheel (100) comprises a wheel body, and a wavelength conversion layer (110) and a light splitting layer (120) adjacent to each other in the axial direction of the wheel body. The wavelength conversion layer (110) is used for converting excitation light into fluorescence; the light splitting layer (120) comprises a first section (121) and a second section (123); and laser light incident on the light splitting layer (120) is split, by means of the first section (121) and the second section (123), into primary color light and excitation light having different transmission directions or different polarization states. When the light splitting layer (120) is in the first section (121), the color wheel (100) emits a primary color light beam under irradiation of an excitation light source (210); and when the light splitting layer (120) is in the second section (123), the color wheel (100) emits an excitation light beam under the irradiation of the excitation light source (210). Since the primary color light beam and the excitation light beam have different transmission directions, the design of a multi-layer spatial optical path is achieved by using a multilayer structure of the color wheel (100), thus effectively reducing the thickness of a light beam when using laser light as a light source, thereby effectively compressing the volume of a light engine using laser light as a light source, and further improving the user experience.
