Abstract: As we all know that energy consumption has increased a lot and sources of energy are limited so in order to meet the increasing demand of energy use of renewable sources of energy is a must. Keeping this in mind in this paper we are discussing about SOLAR LED STREET LIGHT WITH AUTO INTENSITY CONTROL.This street light is driven by solar energy and apart from this it also controls its intensity from dusk to dawn depending upon the brightness. A case study is also done to show advantages of solar led street light compare to that of traditional street light. This street light can save a large amount of electricity compared to the tradition one which are alight to their maximum intensity at all times after they are switched on.
