ABSTRACT:
An illumination brightness and color control system for adjusting the illumination of a plurality of point light sources and method therefor are provided, implemented in a time division manner. A single photosensor senses and samples a point light source for the luminous intensity signal value. Then, the luminous intensity signal value at each wavelength and a target brightness/color value are compute to acquire a corrected current value, and the corrected current value is fed back to a light source driver. Therefore, the brightness/color value of the point light sources is adjusted to be in a steady state.
