Claim 18:
19. A projector, comprising an illumination module, a light valve and a projection lens, wherein
the illumination module comprises a light source device, a lens, and a color wheel module, and is configured to provide an illumination beam, wherein the color wheel module is disposed on a transmission path of the illumination beam and is located between the light source device and the light valve, the lens is located between the light source device and the color wheel module, and the color wheel module comprises a disk, an isolation framework, an assembly member, a wavelength conversion layer, and
a colloidal filler, wherein
the disk is configured to rotate around an axis,
the isolation framework and the assembly member are disposed on the disk,
the isolation framework is located between the disk and the assembly member, wherein an air layer is formed between the disk, the assembly member and the isolation framework, and
the colloidal filler is disposed on the assembly member,
wherein the disk has an optical wavelength conversion region,
the wavelength conversion layer is disposed on the optical wavelength conversion region, and an orthographic projection of the isolation framework and an orthographic projection of the wavelength conversion layer on the disk do not overlap with each other,

the light valve is disposed on the transmission path of the illumination beam to convert the illumination beam into an image beam, and
the projection lens is disposed on a transmission path of the image beam to convert the image beam into a projection beam.
