US 2021/0341826 A1 · PROJECTION APPARATUS

Abstract

The projection apparatus includes: a projection unit, a support frame, a mirror assembly, a mirror balance assembly, and an adjustment device. The projection unit is configured to emit a projection light beam. The mirror assembly is configured to reflect the projection light beam emitted by the projection unit. One end of the support frame is fixed to the projection unit, and the other end of the support frame is suspended. The mirror balance assembly is configured to suspend the mirror assembly to the other end of the support frame that is suspended. The mirror assembly is rotatable about at least one axis of rotation relative to the support frame. The adjustment device is configured to cause the mirror assembly to be inclined along the at least one axis of rotation relative to the mirror balance assembly. In this way, the mirror assembly is flexibly adjusted at a plurality of angles.
