[0003] When the stage light outputs light and shadow, it is usually required that the lens of the stage light can rotate and move along the optical axis of the stage light source. Therefore, it is necessary to set up two driving mechanisms inside the stage light to realize the rotation and axial movement of the lens. At present, for To avoid mutual interference between the two driving mechanisms, the two driving mechanisms are usually installed in different positions and staggered by a certain distance from each other to avoid mutual interference between the two driving mechanisms. However, this will cause the existence of stage lights. larger defect

Embodiment Construction
[0023] Hereinafter, the present invention will be further described with reference to the drawings and specific implementations:
[0024] Such as figure 1 , 2 Shown is a lens transmission assembly of a stage light of the present invention, which includes a frame 10, a mounting plate 30, a first drive assembly, a lens 60, and a second drive assembly, wherein the frame 10 is fixedly connected to the stage light Inside the shell and at the front end of the stage light source, the mounting plate 30 is movably mounted on the rack 10, and the mounting plate 30 is provided with a light-transmitting hole (not shown) outside the light emitting end of the stage light source. The light hole is used for the light from the light source to emit from it. Two guide rods 11 are provided on the frame 10, and the two guide rods 11 extend along the optical axis of the stage light source. The two ends of the plate 30 are respectively fixed at the bottom and the top of the frame 10, and the mounting p...

The lens transmission assembly of the stage light includes a frame; a mounting plate on which a light transmission hole is arranged; a first drive assembly for driving the mounting plate to move relative to the frame along the optical axis of the stage light source, the first drive assembly It includes a first motor, a transmission screw, and a screw nut; a lens pivotally connected to the mounting plate and facing the light transmission hole; a lens for driving the lens to rotate around the optical axis or a line parallel to the optical axis relative to the mounting plate The second drive assembly includes a second motor whose body is fixed on the mounting plate. Through the pivot hole, the transmission screw rod is movably connected in the pivot hole. The present invention can arrange the two motors that drive the axial movement of the mounting plate and the rotation of the lens at different positions on the same axis, and can avoid mutual interference when the two motors work, thereby effectively reducing the volume of the stage light.
Description
Technical field [0001] The invention relates to the technical field of stage lighting, in particular to a lens transmission assembly of a stage lamp. Background technique [0002] At present, in order to meet the requirements of stage performances, stage lights need to involve more lenses. These lenses cooperate with each other so that the stage lights can output more dazzling and diverse light and shadow effects. [0003] When stage lights output light and shadow, usually the lens of the stage light is required to be able to rotate and move along the optical axis of the stage light source. Therefore, it is necessary to install two driving mechanisms inside the stage light to realize the rotation and axial movement of the lens. To avoid mutual interference between the two driving mechanisms, the two driving mechanisms are usually installed in different positions and staggered a certain distance to avoid mutual interference between the two driving mechanisms. However, this will caus...
