System controller and method for a lighting system. The system controller includes a first controller terminal configured to receive a first signal, and a second controller terminal configured to output a second signal to a diver component. The driver component is configured to receive a first current and provide one or more drive currents to one or more light emitting diodes in response to the second signal. Additionally, the system controller is configured to process information associated with the first signal, determine a first time period for the first signal to increase from a first threshold to a second threshold, and determine a second time period for the first signal to decrease from the second threshold to the first threshold.

Systems and methods for intelligent control related to TRIAC dimmers

System controller for a lighting system and method thereof according to certain embodiments. For example, the system controller includes a first controller terminal configured to receive a first signal and a transistor including a first transistor terminal, a second transistor terminal, and a third transistor terminal. Additionally, the system controller includes a second controller terminal coupled to the first transistor terminal, and a third controller terminal coupled to the third transistor terminal. The system controller is configured to determine whether the first signal is associated with a leading-edge TRIAC dimmer based at least in part on the first signal, the leading-edge TRIAC dimmer being configured to receive an AC input voltage associated with at least a first half cycle from a starting time to an ending time.
