LIGHTING SYSTEM AND METHOD

A lighting system has a set of multiple LED luminaires, and combines solar panel power and external grid power. A solar converter converts the output from the solar panel into a first power. Each luminaire is associated with a driver to inject current into the LED lighting unit from the external grid power supply. The LED lighting units of the luminaires are connected together to the solar converter and are thereby driven together by the first power simultaneously. This simplifies the structure.
