Abstract
A projection apparatus comprises a housing with a projection opening, a light source component, a reflective bowl and a driving motor in the housing, and a transparent cover is mounted on the housing and protrudes upwardly out of the projection opening. The light emitted by the light source component is illuminated on the reflective surface, and then the light passes through the transparent cover after being reflected. The light source component, the reflective bowl and the transparent cover can project to produce a cloud effect.
