Title:
STAGE LAMP COLOR TEMPERATURE COMPENSATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/076147
Kind Code:
A1
Abstract:
A stage lamp color temperature compensation system, comprising: a light source (1), a dimming device (3) dimming the light source, a color temperature compensation plate (4) used for performing color temperature compensation on a light out from the dimming device, and a drive mechanism (9) for controlling the movement of the color temperature compensation plate. The drive mechanism drives, according to different variations in color brightness on the color temperature compensation plate, the color temperature compensation plate to enter or leave a light path to implement color temperature compensation. The stage lamp color temperature compensation system conducts, by providing the color temperature compensation plate and the drive mechanism and using the drive mechanism to control the entry and leaving of the color temperature compensation plate, real-time color temperature compensation for lights of various brightness emitted from the light source, thereby making the color temperature of the lights generally consistent during the process of dimming and improving the stability of light output by the lamp. The stage lamp color temperature compensation system is simple in structure and is easily operated. Further disclosed is a stage lamp color temperature compensation method.
