Claim 0:
1. A wavelength conversion module, comprising a wavelength conversion wheel, a driver, a weight member, a first heat insulation layer and a second heat insulation layer, wherein:
the wavelength conversion wheel comprises a rotating plate, and the rotating plate has a first side and a second side opposite to each other;
the driver is connected to the first side of the rotating plate, and the driver drives the rotating plate to rotate around a rotation shaft of the driver as an axis; and
the weight member is attached to the second side of the rotating plate, and the weight member rotates synchronously with the rotating plate around the rotation shaft as the axis,
wherein the rotating plate comprises a heat insulation region and a heat dissipation region, wherein the heat insulation region and the heat dissipation region do not overlap each other;
wherein the heat insulation region comprises a first heat insulation region and a second heat insulation region, the first heat insulation region is located at the first side of the rotating plate and corresponds to a connection position of the driver, and the second heat insulation region is located at the second side of the rotating plate and corresponds to a connection position of the weight member;
the first heat insulation layer is located at the first heat insulation region of the rotating plate and disposed between the rotating plate and the driver; and
the second heat insulation layer is located at the second heat insulation region of the rotating plate and disposed between the rotating plate and the weight member,
wherein the first heat insulation layer and the second heat insulation layer are respectively a surface treatment layer, and the surface treatment layer comprises a ceramization surface layer, a micro-arc oxidation surface layer, an oxide layer, or an inorganic salt layer, or
wherein the first heat insulation layer and the second heat insulation layer are respectively a coated ceramic material layer, a sprayed ceramic material layer, a printed ceramic material layer, or a printed heat insulation plastic material layer.
