Stage lamp capable of achieving automatic focusing

Abstract

The invention provides a stage lamp capable of achieving automatic focusing. The stage lamp comprises a light source, a focusing lens set, a zoom lens set, a front fixed lens set, a distance measurement module, a first motor, a second motor and a microprocessor. The light source, the focusing lens set, the zoom lens set and the front fixed lens set form a lighting system of the stage lamp, the distance measurement module is installed on the stage lamp, the first motor drives the focusing lens set to move, the second motor drives the zoom lens set to move, the distance measurement module is insignal connection with the microprocessor, and the microprocessor controls the first motor and the second motor. According to the stage lamp capable of achieving automatic focusing, compared with theprior art, automatic focusing can be achieved, focusing does not need to be manually conducted on illuminated objects one by one at a live performance, before the live performance is erected and completed, arrangement work of lighting programs can be completed, and the cost of a lightning designer and the budget of a performing unit are saved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an auto-focusing stage light. Background technique [0002] Stage lighting is also called "stage lighting", which is one of the means of stage art modeling. Using stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) Shape the external image of the stage performance and provide the necessary lighting effects (such as wind, rain, cloud, water, lightning). Stage lighting is an important part of the performance space. It is an art that performs a comprehensive visual environment lighting design on characters and specific scenes according to the development of the plot, and purposefully reproduces the design intention to the audience in a visual image. creation. [0003] Nowadays, in view of the large-scale, fast-changing, rich and diverse and clear-cut characteristics of stage performance lighting effects, lighting designers must continue to provide different...

AI Technical Summary

Problems solved by technology

In terms of thousands of light projection points, in order to have a perfect lighting show effect, the heavy work of focusing has naturally become a problem for lighting designers

In addition, the complex and unpredictable location and geographical environment of lighting installations on the performance site also make it impossible for lighting designers to prepare for focusing work before lighting installation

In the existing technology, the lighting focusing work must be manually focused on the illuminated objects one by one at the performance site, which increases the cost of the lighting designer and the budget of the performance unit
