Title: OPTICAL ELEMENT ROTATING DEVICE AND STAGE LIGHTING DEVICE COMPRISING SAME
Abstract:
An optical element rotating device and a stage lighting device comprising the same. An optical element rotating device, comprising a seat (6), a ball fixing rack (1), balls (2), a ball pressure plate (3), an elastic element (4), and a cover (5); the ball fixing rack (1) is sleeved over the periphery of the seat (6); the balls (2), the ball pressure plate (3), the elastic element (4), and the cover (5) are disposed, sequentially from bottom up, between the ball fixing rack (1) and the seat (6). A stage lighting device, comprising an optical element body and the rotating device, and the optical element body is disposed on the seat (6) of the rotating device. The present invention has a simple structure and is easy to use, and can prevent the optical element body from jamming while rotating which would affect the usage effects of stage lights.
