Abstract
A color wheel module is disposed on a transmission path of an excitation beam and includes a driving assembly, a substrate, a fastening element, at least one wavelength conversion layer, and filters. The substrate is connected to the filters, and the filters are fixed between the fastening element and the driving assembly. The substrate includes an outer periphery and a light conversion region located on the outer periphery. The outer periphery extends in an extension direction and has a width parallel to the extension direction. The extension direction and a radial direction of the substrate forms an included angle. The wavelength conversion layers are disposed in the light conversion region. The excitation beam is incident on the light conversion region of the substrate and converted into a conversion beam, and the conversion beam is guided to penetrate the corresponding filter along a direction parallel to the central axis.
