Abstract

A light adjustment module is suitable for being disposed on a transmission path of a light beam. The light adjustment module comprises a housing, a moveable plate, a diffuser, and a light sensor. The housing comprises a base and a cover connected to each other. The cover has a light entrance. The moveable plate is disposed between the base and the cover. The moveable plate moves relative to the housing along a moving direction. The diffuser is disposed on the moveable plate and the transmission path of the light beam from the light entrance. The light sensor is disposed on the base to sense the light beam from the diffuser. The diffuser has at least two regions arranged in the moving direction. The at least two regions respectively have different optical properties. The light beam has different brightness after respectively passing through the at least two regions.
