1. A system for dimming control of one or more light emitting diodes, the system comprising:

  • one or more signal processing components configured to receive a first signal associated with a TRIAC dimmer, process information associated with the first signal, determine whether the TRIAC dimmer is in a first condition or a second condition, generate a second signal based on at least information associated with the first signal, and send the second signal to a switch;

    wherein the one or more signal processing components are further configured to;

    if the TRIAC dimmer is determined to be in the first condition, generate the second signal to cause the switch to be opened and closed corresponding to a modulation frequency; and

    if the TRIAC dimmer is determined to be in the second condition, generate the second signal to cause the switch to remain closed for a first period of time until at least the TRIAC dimmer changes from the second condition to the first condition.
