The RGB Color Matching Experiment apparatus consists of an integrating sphere, a fiber optic spectrometer, a standard light source, and an RGB color mixing system. It uses red, green, and blue LEDs as primary color sources, each of which driven by an independently adjustable power supply. By precisely adjusting the current for each channel to vary the luminous intensity, continuous adjustment of the R, G, and B tristimulus values is achieved, synthesizing light of various colors.
This device is suitable for teaching experiments in color science, photoelectric detection, and related disciplines, helping students deeply understand color mixing principles and colorimetric measurement methods.
