Phosphor wheel device and image projection apparatus including the same

Abstract

A phosphor wheel device and an image projection apparatus including the same are disclosed. The phosphor wheel device according to an embodiment of the present disclosure includes: a plate to rotate around a rotation axis, and including a base extending in a first direction and a protruding member attached to both ends of the base and extending in a second direction intersecting the first direction; a phosphor layer disposed in one region of the base and configured to output light of at least one color by reflecting light incident on the base; and a blade spaced apart from the plate in the second direction and to rotate around the rotation axis. Accordingly, heat dissipation performance may be improved, and high brightness light output may be provided.
