This paper implements a WSN based efficient LED lighting
system to replace the traditional lighting system. Different
connections of LEOs and the design considerations of seriesparallel
LED array are presented. A wireless sensor network
control operation on LED lighting system is presented and
implemented using ZigBee. A current mirror technique is
proposed to solve the current imbalance problem in LED
lamps. It provides an effective measure to save energy by
preventing unnecessary wastage of electricity, caused due to
manual switching of lights when it is not required. This
concept can be used to control lighting system of industrial
areas, college or university campus. The proposed system can
be extended to home automation.
