Reflection device of stage lamp

Abstract

The invention discloses a reflection device of a stage lamp. The reflection device of the stage lamp comprises a base mounted on a unit body, a support arranged on the base in a combined mode, a firstmotor mounted on the base, a second motor mounted on the support, a first transmission mechanism driven by the first motor, a second transmission mechanism driven by the second motor, a mirror holderis pivoted on a rotary shaft of the first transmission mechanism, and a reflection mirror arranged on the mirror holder in a combined mode. The second transmission mechanism is hung on a pivoting part of the mirror holder through a rope ring so that the reflection mirror can be driven by the first motor and the second motor to rotate by variable angles around the light projection direction or around the direction intersecting with the light projection direction so as to reflect a light beam projected by a light source, and the first motor and the second motor can drive the reflection mirror to smoothly rotate with small power.

Description

technical field [0001] The invention relates to the technical field of stage lighting equipment, in particular to a reflection device for a stage lighting. Background technique [0002] To make the performance of the stage play get a better entertainment effect, it needs to have changing lighting effects to cooperate, and the changing light and shadow that appear on the stage are usually produced by using stage lights. Regarding the structure of a conventional stage light, generally a body is provided with a light source that projects light beams longitudinally or horizontally, at least one lens configured along the light projection direction, and a reflector that can be rotated to change the reflection angle of light passing through the lens. [0003] The conventional reflecting device mainly includes a bracket combined on the top of the body, a first motor mounted on the bracket, a revolving frame that can be driven by the first motor, a second motor mounted on the revolvi...

AI Technical Summary

Problems solved by technology

[0004] Although the reflector of the above-mentioned conventional stage lights can change the rotation direction and speed of the slewing frame and the mirror frame from time to time to make the reflector change in various angles relative to the direction of light projection, this conventional reflector has a load. So large that the first motor and the second motor need to have higher horsepower

Furthermore, since the slewing frame carries the second motor and the mirror frame, the load is quite heavy, so a high-horsepower first motor is required to drive the slewing frame smoothly, and the slewing frame and the mirror frame are alternately controlling the direction and speed Transform rotation, so to make the slewing frame or mirror frame can rotate smoothly, it needs to overcome a considerable rotational inertia, resulting in the need for both motors to have high horsepower; in addition, the second motor is carried on the slewing frame that will rotate frequently , resulting in easy loosening of the positioning of the second motor
