As we know that, nowadays energy sources are limited and energy consumption has increased, So renewable energy sources are used to meet the increase in the demand for energy. Keeping this in mind in this article, we are discussing a solar-powered LED street light with auto intensity control. This project is driven by solar energy used to control the light intensity from morning to evening based on the brightness. A case study is also done to demonstrate the advantages of this solar LED street light compared to the traditional street light. Because this solar-powered street light can conserve a large amount of electricity compared to the other lights which are a light to their maximum intensity at all times after they are turned on Solar Powered Led Street Light with Auto Intensity Control Circuit and Its Working.
The solar-powered street light works on the principle of solar cells or PV cells to absorb solar energy in the daytime. The PV cells convert solar energy to the electrical energy. The converted energy is stored in the battery and the solar street lights use solar energy. Nowadays solar street lights are available beside the roads. At night time, the lamps start automatically and it uses the electrical energy which is stored in the battery. Every day this process continues
Light-emitting diode comprises of the chemical compound. When the direct current from the battery passes through the light, then it gives the light. Solar LEDs are available in different shapes, styles, and sizes. Generally, the life span of the light-emitting diode is very high and it requires very little current.
