Color correction in phosphor converted LEDs 520 . A system and method provide color correction in emission spectra of a phosphor converted LED under PWM current drive. A modulation for a driving current signal is determined 810 . A constant-magnitude current signal is modulated based on the determined modulation 820 . The modulated current signal is applied to cause a color correction in the emission spectra 830 . Apparatus to provide color correction in the emission spectra of a phosphor converted LED is provided 520 . A color correction control circuit and a phosphor converted LED coupled to the control circuit are also provided 600. |
