Abstract
A lighting apparatus includes at least one light emitting device configured to receive an optical signal from a source external to the lighting apparatus and a control circuit coupled to the at least one light emitting device and configured to adjust a light output of the at least one light emitting device responsive to the received optical signal. The at least one light-emitting device may include at least one light-emitting diode (LED) configured to receive the optical signal, and the control circuit may include a detector circuit coupled to the at least one LED and configured to detect the received optical signal.
