Solar charging automatic street light design

How do solar powered street lights work?

Abstract— The project is designed for Solar powered pedestal street lights that uses solar power from PV cells. For controlling the charging of the battery a charge controller is been used, and an LDR is used to sense the light on day as well as the evening time. The intensity of street lights is required to be kept high during the peak hours.

What is a solar powered LED street light?

‘SOLAR POWERED LED STREET LIGHT WITH AUTO INTENSITY CONTROL ’. The circuit is stationed in a suitable location that is exposed to sunlight so that immediately it is dark the system automatically switches “ON” the lamps and when the illumination is above 50 lux the lamps are automati-cally switched “OFF”.

What is an automatic street light circuit?

This simplest automatic street light circuit can be assembled quickly by newbie and installed for achieving the intended results. Built around a light activated concept, the circuit can be used for automatically switching ON and switching OFF a roadway lamp or group of lamps in response to the varying ambient light levels.

Can solar power be used as a backup source for street lights?

This paper investigates controlling the street lights from one controller that uses Solar PV energy stored in a battery and the grid as a backup source. The source provided can supply power to all three streetlights from one supply instead of multiple power supplies and controllers. Furthermore, it is also possible to dim the street lights.

What is an automatic street light controller?

This paper presents an automatic street light controller with the help of light dependent resistor (LDR) - and relay timer module. LDR is which also known as photo resistor is made cadmium sulfide . The circuit also consists of a charging controller -. The light intensity is inspected using an LDR sensor.

What is the advantage of an automatic street light system?

2 What is the advantage of an Automatic Street Lamp System? An automatic street light system is a device which detects the ambient light level conditions and automatically switches an attached lamp ON/OFF depending on the level of the ambient light.
