    • A system and method are disclosed for dimming light emitting diode (LED) lamps. A control unit is coupled to a dimmer and LED lamp. The dimmer receives power from an AC source and determines a phase angle of the AC power. The dimmer provides DC power to the lamp based on the phase angle. The control unit sends a control signal to the dimmer during a first portion of each half sine-wave of the received AC power. The control signal causes the dimmer to modify at least one function of the lamp. A plurality of LED lamps may be associated with a single dimmer, and the dimmer may individually instruct the lamps to modify their operational characteristics. The dimmer may send an operational signal back to the control unit. The operational signal may represent end of life information for the associated LED lamp. Other embodiments are described and claimed.
