Light shading element and stage light fixture having same

A light shading element, comprising:

• a base plate having a light-transmitting hole;
• a light shading blade for at least partially blocking the light-transmitting hole;
• and
• a first driving mechanism and a second driving mechanism pivotally connected to the light shading blade and configured to drive the light shading blade to move in a plane, wherein the first driving mechanism is pivotally connected to the light shading blade through a first pivot point, the second driving mechanism is pivotally connected to the light shading blade through a second pivot point, with the first pivot point and the second pivot point located on a same side of the light shading blade,
• wherein movement of the light shading blade in the plane is constrained only by the first pivot point and the second pivot point, the light shading blade is configured to selectively move close to and away from the light-transmitting hole to respectively block and unblock the light-transmitting hole under driving of the first driving mechanism and the second driving mechanism, and
• wherein during movement of the light shading blade, the first pivot point moves along an arcuate trajectory under driving of the first driving mechanism, and the second pivot point is capable of moving along another arcuate trajectory around the first pivot point under driving of the second driving mechanism, when the first pivot point is at any position along the arcuate trajectory.
