Stage lamp optical system with mutually-switched pattern and light beam effect

Abstract

The invention relates to a stage lamp optical system with a mutually-switched pattern and light beam effect. The stage lamp optical system comprises a light source component, a pattern component and a zoom lens component which are positioned in the same main optical axis direction and can emit spot light, and also comprises an optical integrator component which can be switched into the main optical axis, wherein the pattern component comprises a light beam pattern component and a graph pattern component which can switch mutually and enter the main optical axis; the light source component can move forward and backward relative to the pattern component along the main optical axis; when the light source component is moved forward to the first position relative to the pattern component, only the light beam pattern component is switched into the main optical axis; the light rays of the light source component are emitted through the light beam pattern component and the zoom lens component; when the light source component is moved backward to the second position relative to the pattern component, the optical integrator component and the graph pattern component enter the main optical shaft at the same time, and the light rays are emitted through the optical integrator component, the graph pattern component and the zoom lens component. The stage lamp optical system with the mutually switched patterns and light beams has the advantages of low optical loss, high utilization rate and the like.

Description

technical field

[0001] The invention relates to a stage lighting optical system for switching patterns and beam effects. Background technique

[0002] At present, the most widely used functional lamps in the field of stage lights mainly include three types: pattern lights, beam lights, and soft lights. Stage designers and users often choose different functional lamps in a targeted manner according to the needs of use. However, due to the use of a single, complex stage scene, it is necessary to replace and use different types of lamps and lanterns, which is extremely complicated to operate. In order to solve this problem, stage lamps for realizing various light beam effects are also proposed in the prior art.

[0003] Chinese patent CN201320192500.0 discloses a stage lighting system including multiple beam effects at the same time, which includes a light source, a reflective bowl, an optical component 1, and an optical component 2; the optical component 1 is located bet...
