The present disclosure is generally directed to an aircraft cabin LED lighting system and lighting assembly, in which each LED light is paired with and controlled by a separate microcontroller, which is individually addressable. In various embodiments, a lighting control device (e.g., a control panel for flight attendants) transmits pixel data to various lighting assemblies around the cabin. These lighting assemblies include the microcontroller-LED light pairs. Each LED light is multicolor and includes multiple LEDs (e.g., one for each color). The pixel data defines a color scheme and/or animation sequence. Each pixel maps to one of the microcontroller-LED pairs. The microcontroller controls the intensity of each LED of the LED light according to the pixel data it receives.

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.

The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.
