Abstract
Lighting systems for remote placement and powering of a lighting device. The lighting systems include a lighting device for placement on a wall or ceiling and an external power supply selectively attachable to and detachable from the lighting device. The lighting device includes a power receiving structure that receives power from the external power supply and delivers electrical power to a rechargeable battery and/or light source. The external power supply includes a corresponding power delivery structure that delivers power to the power receiving structure of the lighting device. The power receiving and delivery structures may constitute an inductive power transfer system composed of one or more batteries or capacitors, a DC-to-AC inverter, electromagnetic power transfer and receiving coils, and an AC-to-DC convertor or rectifier. Alternatively, the power receiving and delivering structures may constitute direct electrical contacts.
