During the day, solar panel will receive the sunshine energy, then convert to electrical energy and save in the battery, put into use for the street lights in the nights automatically, and cut off during the day time.
Solar LED street lights work with LED lamps, as in light emitting diode lamps. As such, LED-based lamps have a special compound that releases light when direct current from the source battery gets to pass it. LED street lights are practical as a lot of companies have LED lamps available in different styles, shapes, and sizes. Its durable nature also means it can last for as long as 50,000 hours. As it requires very little current to work, it also tends to be much smaller than other lamps. Likewise, the solar panels needed to make solar LED street lamps work are much smaller, and can therefore make them cheaper to build.
- Solar LED street lights rely on the photovoltaic effect, which allows the solar cell to convert sunlight into usable electrical energy. This is done when negatively-charged electrons push solar energy into positively-charged spaces in the cells.
- This process allows solar energy to transfer into the electrons – becoming direct current electricity. Similar to how electricity-based gadgets work, wires from the solar cell are then connected to the battery in order to transfer the fresh direct current electricity from sunlight.
- It’s when nighttime arrives that the solar cell will stop the conversion process as sunlight disappears. Photoreceptors will help shut the solar cell down when there’s not enough sunlight to convert. This is when the battery will start supplying power to the LED lamp via other wiring.
