Abstract
A system for controlling LED light fixtures such that in the event of a loss of the lighting control signal the LED light fixtures may be controlled in a proper and predictable manner. The system includes a Digital Power Module (DPM) that receives the lighting control signal and transmits a control signal to a Fixture Control Module (FCM) connected to the LED lights. In the event the lighting control signal is not received by the DPM, it is adapted to send a backup control signal to the FCM to control the LEDs. Additionally, in the event the DPM fails to send a control signal to the FCM, the FCM is adapted to control the LEDs is a predefined manner such that the LEDs are always functional even with a loss of the input control signal.
