A real-time implementation of solar photovoltaic powered LED interior lighting systems

This paper describes the design and development of an eco-friendly lighting system installed in a modular office room, where artificial lights are indispensable even during daytime. While solar powered lighting systems are recently introduced, the major challenges such as design of suitable power converters as well as power management still persist. In this work, the conventional light fittings are replaced with LED fittings and grid power is replaced by solar photovoltaic power. Optimum configuration of components to design a solar powered LED day-lighting for modular office application is well explained in this paper. A cost comparison between conventional lighting system and solar powered LED lighting system show the real energy conservation achieved by this implement.
