Optical system for stage lamp

Abstract

The invention discloses an optical system for a stage lamp. The optical system comprises a light source, a light condensing device, an effect component, a lens and a multi-reflection mirror surface optical component fixed on the upper part of the lens. According to the optical system, light emitted by the light source is reflected by the light condensing device and converged to become a main light beam along the transmission direction of the light, the main light beam sequentially passes through the effect component and the lens and is reflected out by the multi-reflection mirror surface optical component, the multi-reflection mirror surface optical component at least comprises three reflection mirror surfaces, and at least three stage of linkage mechanisms which can drive the multi-reflection mirror surface optical component to move so as to achieve a three-dimensional dynamic light spot effect are connected to the multi-reflection mirror surface optical component. Light emitted by the light source is reflected by the condensing device and converged to become the main light beam along the transmission direction of the light, the main light beam passes through the effect component and the lens and is reflected out to form a plurality of light spots, and the multi-reflection mirror surface optical component is driven by the linkage mechanisms to move so as to form a plurality of dynamic light spots. When the optical system is applied to the stage lamp, a lighting effect that a plurality of dynamic light spots are simultaneously shown by a single lamp is achieved.

Description

technical field [0001] The invention relates to an optical system for a stage lamp, which belongs to the transformation technology of the optical system for a stage lamp. Background technique [0002] The role of stage lighting in modern stage performances is particularly important, and it can play the following roles: ① Lighting performances, so that the audience can see the actors' performances and scenery images clearly; ② Guide the audience's sight; ④Create the space environment needed in the play; ⑤Render the atmosphere in the play; ⑥Display the time and space transitions, highlight the contradictions and conflicts in the play, strengthen the rhythm of the stage, and enrich the artistic appeal. Commonly used lights include: spotlight, beam light, soft light, follow spot light, astigmatism light, scanning light, etc. [0003] The core technology of stage lighting is the design of optical system and control method. The design of optical system is the soul of lighting pro...

AI Technical Summary

Problems solved by technology

The optical system structure used in the existing stage lamps is relatively simple, so that it is difficult for the stage lamps to form a dynamic spot effect, and the use effect of the stage lamps is not good
