Patent abstract
A light emitting diode retrofit lamp for replacement of fluorescent lamp or tube driven by fluorescent ballast is provided. The retrofit lamp consists of an enhanced circuit that overcomes the compatibility issues with the fluorescent ballasts. The circuit of the retrofit lamp comprises a deflickerizer circuit that prevents the flicker in the lamp when the lamp operates in the frequency range of 0.1 Hz to 60 Hz. The deflickerizer circuit further provides a method to align frequency with the ballast frequency and maintains phase to avoid low frequency interference.
