Method and apparatus for computing illumination mixed lights, computer device and storage medium

A method for computing illumination mixed lights from a light source, comprising:

• acquiring a first chromaticity coordinate point corresponding to a first colored light, and acquiring a second chromaticity coordinate point corresponding to a second colored light;
• acquiring a target chromaticity coordinate point, and computing a first lumen mixing ratio of the first colored light and the second colored light according to the target chromaticity coordinate point, the first chromaticity coordinate point and the second chromaticity coordinate point;
• determining a middle chromaticity coordinate point corresponding to a middle-colored light obtained by mixing the first colored light and the second colored light according to the first lumen mixing ratio;
• determining a first compensation colored light and a second compensation colored light according to the middle chromaticity coordinate point and the target chromaticity coordinate point;
• and
• conducting compensation computation on the middle-colored light according to the first compensation colored light and the second compensation colored light, and determining a second lumen mixing ratio corresponding to the first compensation colored light, the second compensation colored light and the middle colored light to become the target chromaticity coordinate point.
