Abstract: A fluorescent color wheel includes a substrate, a phosphor layer, and a fan blade structure. The substrate has a front surface, a rear surface opposite to the front surface, and a plurality of through holes communicating the front surface and the rear surface. The phosphor layer is disposed on the front surface. The fan blade structure includes a heat-dissipating plate and a plurality of first fan blades. The heat-dissipating plate has a first surface attached to the rear surface of the substrate. The first fan blades are disposed on the first surface and respectively pass through the through holes to protrude out from the front surface of the substrate.

Abstract: A projection device includes a prism set, a digital micro-mirror device, a reflective component and a heat dissipation module. The prism set includes a light-incident side and a mirror-corresponding side opposite to each other, and includes a first light-emitting side and a second light-emitting side adjacent to each other. The digital micro-mirror device spatially corresponds to the mirror-corresponding side. An incident light is transmitted through the light-incident side to irradiate the digital micro-mirror device. When the digital micro-mirror device generates an on-state light, the on-state light is outputted through the first light-emitting side. When the digital micro-mirror device generates an off-state light, the off-state light is transmitted toward the reflective component and outputted through the second light-emitting side. The heat dissipation module spatially corresponding to the second light-emitting side is configured to absorb and convert the off-state light for heat dissipation.
