Problems solved by technology

[0005] However, most of the projection lights used on the stage need to be swayed to make the light shake and produce a more cool stage effect. At present, most of the existing stage projection lights need to be manually controlled to achieve the swing function, and the automatic rotation effect is not good. needs to be improved

Abstract

The invention discloses a projection lamp with automatic reciprocating capability for a stage. The lower end of a driving shaft is fixedly connected with a semi-cone gear which has teeth on one half and has no teeth on the other half, and bevel gears are arranged on two sides of the semi-cone gear respectively and fixedly connected to the left side of a threaded rod; a ferrule is in threaded connection to the threaded rod, the upper part of the ferrule is rotationally connected with the lower end of a connecting rod, the upper end of the connecting rod is rotationally connected with the lowerpart of a lamp body, two sides of the lower end of a cage are fixedly connected with movable rods respectively, the lower parts of the movable rods are sleeved with sleeve seats, the movable rods arefurther sleeved with damping springs, the upper ends of the damping springs are in butt joint with the lower surface of the cage, and the lower ends of the damping springs are in butt joint with the sleeve seats. The toothed part of the semi-cone gear is meshed with the bevel gears back and forth to drive the threaded rod to rotate back and forth forwards and reversely, the threaded rod drives theferrule to drive the connecting rod to drive the lamp body to reciprocate around the upper end of a support rod, and elastic connection between the cage and a bottom plate is realized by the movablerods and the sleeve seats connected by the damping springs.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a projection lamp for a stage that can automatically reciprocate and swing. Background technique [0002] Projector lamps have been promoted and used more and more widely in recent years, including single buildings and exterior wall lighting of historical buildings. The interior and exterior lighting of the building, and indoor partial lighting. Green landscape lighting, billboard lighting. Medical, cultural and other special facilities lighting. Atmosphere lighting in bars, dance halls and other entertainment places. [0003] LED projection lamps are also called linear LED projection lamps, etc., because of their long strip shape, some people call them LED line lamps, which are mainly used for architectural decoration lighting, and are also used to outline the outline of large buildings. , its technical parameters are roughly similar to those of LED projection lamps. Compared with the c...
