Photovoltaic and led combination for recycle waste of light energy / Mohd Fadhillullah Abdullah

This report presents a proposal for an energy conservation system to be developed by combination of two main devices. Those two main devices are LED (light emitting diode) and PV module (photovoltaic). Since LED device is turn ON, light emitted to surrounding. That light from LED that was emitted will lose in surrounding in term other energy. What was concern in this project, why cannot turn that lose energy into electrical energy. The aim of this project is to develop an energy conservation system by which using light energy from light source that was emitted lose to surrounding turn into electrical energy . That electrical energy produced will recycle to be used to power up the light system. This combination system looks like a small standalone photovoltaic systems with LED as load. The system uses battery that has two functions as main source to light LED and as storage for photovoltaic system. The energy sources drain by photovoltaic effect on two conditions. First condition the energy gain from sun during daylight that capture by photovoltaic module. Second condition the energy gain by extract waste of light energy to electrical energy from LED light source. The designation involve of choosing the photovoltaic module type, photovoltaic maximum power, photovoltaic system parameter, battery capacity, charging and discharging rate of battery and controller and LED parameter.
