Sustainable PV-powered FPGA-controlled high brightness LED illumination systems

This paper presents a road map for the design and development of sustainable hybrid Field Programmable Gate Array (FPGA) controlled High Brightness Light Emitting Diode (HB LED) illumination systems. The proposed hybrid system design presents the foundation for future sustainable high efficiency illumination systems. In this system design, an FPGA is used to individually control an array of HB LEDs. Each HB LED can operate in a different mode defined by the user. Photovoltaic (PV) panels-based systems are used as the primary source of energy in this system while the electric grid is used as the backup source that supplies power to the HB LEDs only when the power of the PV system is not sufficient to supply all the system HB LEDs and the PV system batteries are depleted below the minimum level set in the system design. This new hybrid design should serve as an important link between the current AC-based illumination systems and future sustainable DC-based solar illumination systems. Since computer simulation is an important tool for future illumination system design and analysis, it is presented to assist designers in studying different designs and in optimizing the one to be implemented.
