PURPOSE: A full-white LED(light emitting diode) correction system and a method are provided to secure uniform optical reproducibility by reflecting a corrected value on an error at a light emitting state. CONSTITUTION: An LED(light emitting diode) module(10) mounts an LED chip(20), a driver(22), a nonvolatile memory(26), and a controller(24). A measuring instrument(12) measures a light emitting state for each element of the LED chip. A correction device(14) manages correction database. The correction device provides a light control signal to the controller. The correction device receives a measurement result of each element, compares the measurement result with a standard color coordinate value and generates a corrected color coordinate value.
