Zusammenfassung:An apparatus for controlling a light emitting diode (LED) module having a light intensity compensation function includes a light intensity sensor measuring intensity of light irradiated by the LED module depending on a current value, based on a predetermined light intensity signal; a compensation signal generating unit generating a compensated light intensity signal to compensate for an error between measured light intensity and predetermined light intensity; and a pulse width modulation signal generating unit allowing the LED module to irradiate light having uniform brightness in such a manner that a pulse width modulation signal depending on the compensated light intensity signal is applied to an LED driver, in an apparatus for controlling LED lighting including an LED driver.
