Title:
STAGE LIGHT SYSTEM HAVING BEAM DIVERGENCE ANGLE VARYING WITH VOLTAGE
Document Type and Number:
WIPO Patent Application WO/2021/063138
Kind Code:
A1
Abstract:
A stage light system having a beam divergence angle varying with voltage. The system comprises a light source (100), a condenser component (200) for converging light emitted by the light source (100), and a liquid crystal light modulation glass component (300) disposed in a direction of light emission of the light source (100). A beam divergence angle of the liquid crystal light modulation glass component (300) gradually increases or decreases as an applied voltage increases. In the stage light system having a beam divergence angle varying with voltage, different voltages can be applied to the liquid crystal light modulation glass component (300), so as to change the direction of arrangement of liquid crystal molecules in the liquid crystal light modulation glass component (300), thereby changing the divergence angle of a light beam passing therethrough. The invention enables stage light patterns or the size of light spots to be adjusted without having to reserve space in a stage light for a focusing lens (410) and a magnifying glass component (440), thus saving the space required for the movement of the focusing lens and the magnifying glass component, and reducing the size of the stage light.
