Stage lighting cutting device capable of changing light spot shape

Abstract

The invention provides a stage lighting cutting device capable of changing a light spot shape. The stage lighting cutting device capable of changing the light spot shape is mounted in a stage lamp. The stage lighting cutting device capable of changing the light spot shape comprises a machine body, a cutting plate component and a pushing device, wherein the machine body is fixedly mounted in the stage lamp, the cutting plate component is movably mounted on the machine body, and the pushing device is fixedly mounted on the machine body; the cutting plate component can shield and cut light beamsof a light source during moving on the machine body; the pushing device comprises a fixing base, a fixing sleeve and a movable sleeve, wherein the fixing base is fixedly mounted on the machine body, the fixing sleeve is fixedly mounted on the fixing base and arranged far away from the machine body, and the movable sleeve sleeves the fixing sleeve in a slideable manner; and a plurality of pushing rods are movably inserted in the side wall of the movable sleeve. Through the movable sleeve, the pushing rods can be driven to move to drive the machine body to move; after the machine body moves faraway from or approaches the light source of the stage lamp, the distance between the machine body and the light source can be changed to change the brightness of the light spot.

Description

technical field [0001] The invention relates to the technical field of lighting cutting, in particular to a stage lighting cutting device capable of changing the shape of a light spot. Background technique [0002] Lighting is an essential part of stage performances. At the same time, the shape of the light can be changed to the required shape and brightness according to the needs of the stage. When adjusting the shape of the light spot, the light spot can be formed or changed by blocking and cutting. The required shape, but the brightness of the spot cannot be adjusted by blocking and cutting. In the prior art, the brightness of the spot is often changed by adjusting the output intensity of the light source through frequency conversion. Frequency conversion control has higher requirements on the transformer. During the adjustment process , It is easy to reach the breakdown voltage of the transformer, causing damage to the light source and affecting the stage effect. Conte...
