Design of LED lighting system based on solar power supply

Can a solar LED lighting system be implemented in DC?

The suggested lighting system was implemented in DC to present high efficiency and scotopic human sensitivity. Huang et al. [ 7] introduced a high-performance charge/discharge controller for a stand-alone solar LED lighting system.

Why is high-efficiency PV and LED lighting important?

Since using energy-efficient lighting is an important factor for sustainable development and energy strategies, the combination of high-efficiency PV with LEDs allows the release of stand-alone PV lighting systems that provide a practical energy-efficient solution for lighting systems [ 3 ].

How can solar energy-driven lighting improve the safety of buildings & cities?

The use of such a reliable solar energy-driven lighting system, with maximum time when the light is “on”, will eliminate the sudden-death of light problem present in conventional photovoltaic (PV) outdoor lights and, therefore, will enhance the natural surveillance and feeling of safety in sustainable buildings and cities.

How smart is the new LED light system?

The smartness of the new system comes from the fact that the system main controller has continuous monitoring capabilities to measure the level of energy in the battery and, based on the state of charge of the battery, the controller decides the level of illumination of the light, to maximize the time when the light is on.
