A light shading device having curved guidance includes a light passing hole for light beams passing therethrough and at least one pair of shading blades arranged opposite one another. Each pair of shading blades respectively have a shading edge for shading light beams at a side close to each other, while the two ends of the side away from each other are respectively connected with a double-link arm which includes a first connecting rod and a second connecting rod pivoting each other, the other end of the first connecting rod is connected to the corresponding shading blade, and the other end of the second connecting rod is connected to a driving element. A guide element is further provided for limiting a guide point on each shading blade to move along a curved path on the plane where the corresponding shading blade is located.

Light shading device having curved guidance and stage light fixture

A light shading element includes a base plate having a light-transmitting hole, a light shading blade for at least partially blocking the light-transmitting hole, and first and second driving mechanisms pivotally connected to the light shading blade to drive its movement in a plane. The first and second driving mechanisms are pivotally connected to the light shading blade through a first pivot point and a second pivot point, respectively. 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. 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.
