Abstract

A mobile lighting system to integrate multiple power sources into a unified platform for portable, uninterrupted illumination. In various embodiments, the system includes a light source, an AC socket connector, internal rechargeable batteries, and external battery packs to thermally isolate high-temperature LED zones from power storage to reduce risk of thermal runaway. External interfaces include a USB Power Delivery port enabling bidirectional power transfer, dynamic role switching between source and sink, and data communication with mobile devices. Solar panel input may supplement charging. Intelligent switching logic, executed by stored instructions in a controller, manages transitions between AC, internal, and external power sources based on sensor-detected availability, charge levels, and user-defined priorities. Modular features include an on-device manual switch for on/off and dimming control, hot-swappable batteries, and real-time control and diagnostics through visual indicators or a connected application.
