The provision of street lights is a useful public infrastructure that facilitates smooth navigation in the absence of natural light. One way of containing the ill effects of climate change is by switching over to energy-efficient LED solar lights. These absorb solar energy when the sun is out and convert it into usable electrical energy. Doing so repeatedly each day enables a solar street light to shed power during the nights. The light-emitting diode (LED) makes these lamps a practical alternative as they work on minimal current and last longer. As sunlight disappears, the energy conversion process comes to a halt, and the LED lamp relies on its battery for power supply. A viable alternative to traditional street lights is the solar-powered ones as the latter are environment-friendly. By ...
