The driving mechanism includes a driving member and a swing arm. One end of the swing arm is movably connected to the case and the opposite end thereof is fixedly connected to the diaphragm sheet. The driving member is movably connected to a position between two ends of the swing arm. The driving member is controlled by a control unit to move the swing arm and thus the diaphragm sheet, in order to control the amount of light.
