SYSTEM AND METHOD FOR POWERING AND CONTROLLING A SOLID STATE LIGHTING UNIT

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.
