Title:
STAGE LAMP HAVING CONTROLLABLE COLOR RENDERING INDEX, AND ADJUSTMENT METHOD FOR COLOR RENDERING INDEX OF STAGE LAMP
Document Type and Number:
WIPO Patent Application WO/2022/252373
Kind Code:
A1
Abstract:
A stage lamp having a controllable color rendering index, and an adjustment method for a color rendering index of a stage lamp, wherein the stage lamp having a controllable color rendering index comprises a case, an arm pivotally connected to the case, a lamp holder pivotally connected to the arm, a light source (200) located in the lamp holder and used for generating a light beam, and a color rendering piece (110) located in the lamp holder and used for changing a color rendering index of the light beam. The color of the color rendering piece (110) changes gradually, and the color rendering piece (110) is driven by a driving mechanism (150) to freely cut in or out of the light beam, and stays at a specified position to intercept the light beam by using different regions. The color rendering piece (110) has a filtering function for adjusting the color rendering index of light. The color rendering piece (110) is disposed on a path of the light beam generated by the light source (200), and the driving mechanism (150) is utilized to control the color rendering piece (110) to cut in or out of the light beam. Due to the difference in the area of the color rendering piece (110) cutting in or out of the light beam, filtering effects of different degrees are generated, and a user can adjust, according to the requirements of a scene scenario, the area of the color rendering piece (110) cutting in or out of the light beam, to obtain a required light beam color rendering index.
