Abstract
An illumination brightness and color control system and method therefor are provided. A broadband light source monitor senses and samples a point light source for a luminous intensity signal value. Then, a corrected current value is computed based on a difference between the luminous intensity signal value and a target brightness/color value, and a driving current generated by a light source driver to drive the point light source is adjusted according to the corrected current value.
