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.

Abstract: Various embodiments of a method and apparatus for providing light that is resilient to power outages are disclosed. The apparatus is a device that includes a primary light source, which includes an AC-to-DC converter that converts the AC power from a light socket to DC power. The device includes a secondary power source, as a backup, having an internal or external battery and a light source electrically connected in parallel. In some embodiments, the light source resides on a flexible, printed circuit board. In some embodiments, the device includes a sensor that senses the loss of AC power. In some embodiments, in response to the sensor sensing the loss of AC power, the light shuts off or fades out after a predetermined time period. In some embodiments, the user can stop the light from turning off or fading out by pressing a button.

Abstract: An ultra-compact power bank device implementing a microcontroller based intelligent power routing mechanism for controlling power flowing from a solar panel and a battery to a USB port of a load device. The microcontroller controls a unique combination of simultaneously performed functions. A booster circuit provides higher voltage and fixed power at the output of the power bank.
