Abstract

A remotely adjustable lighting device configured to an operational mode customized for the geographic location of the device. The lighting device is powered by a battery provided with solar charging. The lighting device, under control of an integral controller, is turned off and on for an illumination period as a function of both local sunrise and sunset times determined by a combination of time and date information and GPS positioning. The luminosity of the lighting device is autonomously controlled as a function of battery charge and the determined required illumination period. The solar charging system is oriented by the controller to optimize its energy collection by periodical adjustments.
