Solar Powered Led Street Lights With Auto Intensity Control

Some of the main advantages of them mainly include.

Solar powered led street lights with auto intensity control. This paper explores the combination of a solar pv with mppt supplying power to a street light equipped with leds with automatic intensity control through a dc dc converter. Load intensity control circuit using 18v solar panel we will charge 12v battery. As the name suggests it makes use of street lights so simple. The led street light automatically turns on after the dusk and turns off after the dawn.

Whenever the solar charge is low the circuit utilizes the power from the battery if the battery goes into deep discharge then it utilizes power from solar power then the led s flashes light. Solar powered led street light with auto intensity control is a new alternative to traditional street lightning system. Thus this is all about solar powered led street light with auto intensity control. Working of a solar powered led street light with auto intensity control circuit and its working.

We hope that you have got a better understanding of this concept. Hence the auto intensity control of street lights is achieved with the above circuit which has an ldr an rtc a pic microcontroller and an led array. Solar powered street lights are environmentally friendly cost effective and energy saving. The solar powered led street lights activate from dusk to dawn.

Solar powered led street lighting with auto intensity control ch kavitha swathi satyaprakash vinitha abstract the project is designed for led based street lights with an autocontrol that uses solar power from photovoltaic cells. V darshil h shah vinit g parikh abstract this report describes the design of the solar powered led street light with auto intensity control the project based on 2 modules. Charge controller circuit 2. Alternative circuit the circuits shown above uses array of leds as street light in order to save power.

The street light is being equipped with a li ion battery whose charging and discharging are also controlled by dc dc converters. No need to control manually energy saving a bunch of leds reduces the cost a lifetime of street lights can be increased detection of vehicle good stability in the cold sensitivity is high based on the light intensity it works completely automatic designing is very simple.
