Light-shielding protection type stage lamp

Abstract

The invention discloses a light-shading protection type stage lamp in the technical field of stage lamp protection, which comprises a lamp holder, a dust cover is fixedly connected to the outer wall of the lamp holder, a steering mechanism is rotatably connected to the lamp holder, a shading mechanism is fixedly connected to the outer wall of the lamp holder, a stage lamp is fixedly connected to the end surface of the lamp holder, the end face of the lamp holder is slidably connected with a sweeping mechanism. Under the joint cooperation of a turnover gear, a square shifting block, a rack, a shifting plate and an air cylinder, when the stage lamp needs to work, a second sealing plate can be automatically turned over by 270 degrees, just abuts against the outer side of a first sealing plateand automatically moves downwards along with the first sealing plate and a third sealing plate to achieve turnover, folding, contraction and shielding removal, and therefore the shading mechanism iscompact in structure and high in practicability. When the stage lamp is not used, the light shielding mechanism is reset, shielding protection is recovered, damage to the stage lamp due to direct sunlight in non-working time is avoided, and the service life of the stage lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of stage lamp protection, in particular to a light-avoiding protection type stage lamp. Background technique [0002] Stage lights are a type of lamps used for lighting and achieving certain light effects in stage performances and film and television shooting. It helps to express the content of the program, reflects the author's creative intention, brings out the artistic atmosphere, and enables the audience and the camera to get the correct color feeling and exposure. In the field of stage lighting, the existing stage lights are generally supported by support seats, The arm and the lamp head are composed of three parts. The support base and the support arm, and the support arm and the lamp head are usually connected by a rotating shaft assembly, so that the lamp head can rotate horizontally and vertically. [0003] In the prior art, some invention cases of light-shielding protection stage lights are disclo...
