Outdoor energy storage LED

What is a smart LED outdoor lighting system?

A smart LED outdoor lighting system based on the level of energy stored in the battery was designed by Kiwan et al. . A review of thermal energy storage for storing cold energy with various solid-liquid low-temperature phase change materials was performed by Nie et al. .

Can LED lighting save energy?

A comparison between LED lighting using solar power and grids, with traditional mercury lamps, regarding cost, found that 75% of energy can be saved by using LED lighting. Considering the payback and lifetime, LED lighting using solar power or grid power were found to be economically feasible.

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.
