Autonomous Unit for Emergency Lighting System for Aircraft, eVTOLs, VTOLs and Rotorcraft

A light unit executes up to three different functions (cabin area illumination, individual/dedicated/decorative illumination and emergency illumination) and an emergency illuminated sign unit, each one with an internal controller and a rechargeable capacitor. An example non-limiting embodiment also provides a cabin light system and an emergency lighting system, where each illumination unit (light source or illuminated sign) is as described above.
