Abstract:
The present invention relates to an optical element driving mechanism, including a base, a holder, a frame and a light intensity adjusting assembly. The holder is movably connected to the base and carries the optical element, wherein the optical element has an opening and an optical axis so that light passes through the opening to the optical element. The frame is connected to the holder and the base. The light intensity adjusting assembly is disposed on the frame. The light intensity adjusting assembly includes a first shutter, a second shutter and a shutter driving member. The second shutter is disposed between the first shutter and the frame. The shutter driving member is disposed between the second shutter and the frame to drive the first shutter and the second shutter.
