1. A method for controlling light emitting diode (LED) light fixtures, the method comprising:
- monitoring a clock source signal to identify the presence of a feature in the clock source signal;
generating a trigger signal with a triggering module in response to identifying the presence of the feature in the clock source signal;
providing the trigger signal to each of a plurality of light fixtures to commandeach of the plurality of light fixtures to stop outputting light; and
measuring ambient light with a light sensor located with the plurality of light fixtures;
wherein the clock source signal is a power line communication signal carried by an AC or DC signal used to provide power to the plurality of light fixtures.

6. A light fixture control system, the system comprising:
-
a monitoring module that monitors a clock source signal to identify the presence of a feature in the clock source signal; a triggering module that generates a trigger signal in response to identifying the presence of the feature in the clock source signal; a command module that provides the trigger signal to each of a plurality of light fixtures to command each of the plurality of light fixtures to stop outputting light; and a ambient light module that monitors ambient light measured in proximity to the plurality of light fixtures; wherein the clock source signal is a power line communication signal carried by an AC or DC signal used to provide power to the plurality of light fixtures. - View Dependent Claims (7, 8, 9, 10)
