Abstract: A system for powering an excimer bulb includes a first inductor configured to be coupled to a first terminal of the excimer bulb. The system further includes a first transistor coupled to the first inductor and having an on state configured to allow current to flow through the first inductor and an off state. The system further includes a second transistor configured to be coupled to the first terminal of the excimer bulb and having an on state configured to allow current to flow through the excimer bulb and an off state. The system further includes a controller coupled to the first transistor and the second transistor, and to control operation of the first transistor and the second transistor to power the excimer bulb.

Abstract: An aircraft emergency lighting system is disclosed. This emergency lighting system may include interior emergency lighting, interior ambient light sensors, exterior emergency lighting, and exterior ambient light sensors. The interior emergency lighting, the exterior emergency lighting, or both, may be controlled based upon an input of the interior ambient light condition (e.g., using an output from at least one of the interior ambient light sensors) and based upon an input from at least one of the exterior ambient light sensors.

Abstract: An end of life detection system for an anti-collision light may comprise a reflector and a plurality of LEDs located around an exterior of the reflector. A trend LED and reference LED may be located in an interior of the reflector. The trend LED may be powered on with plurality of LEDs. The reference LED may be powered on during an initial power-on self-check and turned off after completion of the initial power-on self-check.

Abstract: 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.
