The paper presents both chrominance uniformity and color temperature compensation for RGB LED lighting illumination. A self-developed color optical sensing module and an integrating sphere were used to measure the color characteristics of LED pixels. Firstly, the transfer coefficients for each color measurement were calibrated. A calibrated sensing module was applied to inspect the color characteristics of 3 in 1 color LED modules. With the required target color chrominance or color temperature, the compensated RGB lighting ratio can be derived according to the mixed light formula associated with original RGB measurement. The experimental results from the 4×4 LEDs show that the deviation of white chrominance by using a 3 in 1 LED module is about 0.1001 before compensation, but the average color deviation is reduced to 0.002 and the average color temperature deviation is less than 71K after compensation by using the proposed method. |
