摘要： For providing a compact high-precision lighting control means to drive an LED lighting module, a lighting control integrated circuit is set forth to perform an accurate lighting control. At least one nonvolatile memory is embedded in the lighting control integrated circuit for storing a plurality of lookup tables. One lookup table provides related data for setting the driving currents of the LED lighting module based on spacing or pitch of LED disposition of the LED lighting module. Another lookup table provides related data to recover uniformity for different LED damage situations of the LED lighting module. The other lookup tables are applied to perform compensation processes on the driving currents concerning temperature variation, ambient light intensity, aging degradation, and power-on time. In addition, a signal processing unit, a pulse-width-modulation signal generating module, and a driving module are incorporated in the lighting control integrated circuit for signal processing and current driving.
