Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0029] like figure 1 As shown, a focusing and zooming system for stage lamps includes a total support frame 10 and a fixed frame 20 arranged thereon. The middle part of the fixing frame 20 is hollowed out, and a cavity 201 is surrounded by its side wall and the overall supporting frame 10 . The cavity 201 is vertically provided with a sliding guide rail 40 and a guide rod 50 , that is, the two ends of the sliding guide rail 40 and the guide rod 50 are respectively fixed between the overall support frame 10 and the fixing frame 20 . The sliding guide rail 40 is sequentially provided with a first slider 41 and a second slider 42 from top to bottom. One end of the first slider 41 that connects the focus assembly to the slide rail 40, and the other end of the focus assembl...

Abstract

The invention discloses a focusing and zooming system for stage lamps, comprising a main support and a fixing frame arranged on the main support, wherein the middle part of the fixing frame is hollowed; the side walls of the fixing frame and the main support are defined to form a cavity; a slide guide rail and a guide rod are vertically installed in the cavity; the slide guide rail is sequentially provided with a first slide block and a second slide block from top to bottom; one end of a focusing module is connected to the slide guide rail by the first slide block; the other end of the focusing module is disposed in a corresponding part of the guide rod; one end of a zooming module is connected to the slide guide rail by the second slide block; the other end of the zooming module is placed in a corresponding part of the guide rod; and the focusing module and the zooming module are driven by a first stepper motor device and a second stepper motor device respectively. The system automatically focuses and zooms, so as to be convenient to operate; and an excellent pattern color effect is conveniently obtained to satisfy the requirements for a modern stage.

Description

technical field [0001] The invention relates to the field of stage lighting, in particular to a focusing and zooming system for stage lighting. Background technique [0002] As the current market has higher and higher requirements for the richness and diversity of stage art, when arranging the stage, it is necessary to constantly change the stage lighting and background effects. And this is mainly achieved through the transformation of the rocking light. [0003] At present, in the field of stage rocking lights, the focusing or zooming components are mostly fixedly installed in the lamps. In addition, in the process of operation, continuous manual transformation is required. The general process is to first confirm the desired lighting effect, and then manually adjust the focus lens and zoom lens. In this process, in order to reduce the spherical aberration and chromatic aberration of the lens, it is necessary to repeatedly adjust repeatedly, which greatly consumes manpowe...
