LED lighting system with distributive powering scheme
A linkable linear light emitting diode (LED) system provides apparatus and method for mechanically, optically, and electrically linking multiple LED modules disposed over a wide and separated area of a ceiling system. Openings can be cut in ceiling tiles of a drop ceiling system and the LED lighting modules are coupled to the tile through the opening, with the tile being sandwiched between different portions of the module. A remote driver system is placed within the drop ceiling above the tiles and provide multiple connectors for powering a multitude of lighting modules. Certain of the LED lighting modules include both input and output connectors for both receiving power or data and providing power or data to other modules. In this manner, some of the modules act as master LED lighting modules and those receiving power and/or data therefrom are act as slave modules.
