摘要： The present disclosure provides a lighting system. In one example, the lighting system includes a circuit board including a plurality of light emitting groups, an integrated circuit electrically coupled to the light emitting groups, a rectifier circuit electrically coupled to the integrated circuit and configured to generate a rectified sine waveform of a power source, and a dimmer circuit electrically coupled to the integrated circuit and configured to transmit a dimming signal to the integrated circuit. In one case, the integrated circuit is configured to modify a power current of the light emitting groups to globally control an emission intensity of all of the light emitting groups uniformly in accordance with the dimming signal.

摘要： The present disclosure provides a method for adjusting output of a lighting system. In one example, the method comprises providing to an integrated circuit a rectified sine waveform of a power source, providing to the integrated circuit a dimming signal corresponding to a dimming profile, modifying the rectified sine waveform into a truncated rectified sine waveform in accordance with the dimming signal, and selectively turning on or off a number of light emitting diodes in accordance with the truncated rectified sine waveform to produce a light output.
