Solar Powered Led Street Lights With Auto Intensity Control

We hope that you have got a better understanding of this concept.

Solar powered led street lights with auto intensity control.

The solar powered led street lights activate from dusk to dawn. Solar powered led street light with auto intensity control is a new alternative to traditional street lightning system. There are many advantages of this system over traditional street lights. 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.

As the name suggests it makes use of street lights so simple. 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. This ppt explained on led based street lights with auto intensity control using solar power from photovoltaic cells and photovoltaic panels are used for chargi slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising. Load intensity control circuit using 18v solar panel we will charge 12v battery.

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. The street light is being equipped with a li ion battery whose charging and discharging are also controlled by dc dc converters. Alternative circuit the circuits shown above uses array of leds as street light in order to save power. 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.

Some of the main advantages of them mainly include. 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. Working of a solar powered led street light with auto intensity control circuit and its working. Thus this is all about solar powered led street light with auto intensity control.

The led street light automatically turns on after the dusk and turns off after the dawn. Solar powered street lights are environmentally friendly cost effective and energy saving.
