This is the simple and cost effective automatic LED Emergency Light Circuit with light sensing. This system charges from main supply and gets activated when main supply is turned OFF. This emergency lamp will work for more than 8 hours (depending the battery capacity and the power consumed by the LEDs).
An introduction: Needs no manual operation for switching ON and OFF. When there is a need of light it automatically switches ON. When darkness rises to a certain level then sensor circuit gets activated and switches ON and when there is other source of light i.e. daytime, the street light gets OFF.
An Automatic LED Emergency Light circuit is designed to turn ON when there is no adequate lighting or if the power supply is cut-off. Earlier fluorescent lights were used to build such circuits. But the use of LED's have proven to provide adequate lighting for a longer period before draining the ...
These circuits can be used for different automatic light sensing projects including automatic night lamp, automatic street light controller, dark sensor circuits, etc. Automatic night lamp circuit using IC 555 and LDR. An automatic night light circuit controls the switching of light by sensing the surrounding light intensity.
Followings are the main components of automatic control of street lights : Light sensor : Light sensor is used to sense amount of light. There are many light sensors available in market but Light dependent resistor (LDR) is used as a light sensor.

Automatic Street Light Dimmer Using Motion Sensor will save power by reducing its brightness when no one is passing in the road, PIR sensor will detect the motion in the road. The signal from the PIR sensor will activate the circuit and increase the brightness, this street lamp circuit not using microcontroller thus we can reduce cost.
Here in this project we are going to make a Simple Automatic Street Light Controller Using Relay and LDR. This circuit is simple and can be built with Transistors and LDR, you don't need any op-amp or 555 IC to trigger the AC load.

Circuit Diagram 1. Automatic Street Light Control System.(Sensor using LDR & Transistor BC 547.) Very Simple. We have tried this one in this tutorial but you can also try the second one mentioned below.
AUTOMATIC STREET LIGHT CONTROL SYSTEM (MINOR PROJECT) ABSTRACT Automatic Street Light Control System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor ...
Light Sensor Circuit Working Operation. The light sensor circuit is an electronic circuit designed using (light sensor) LDR, Darlington pair, relay, diode, and resistors which are connected as shown in the light sensor circuit diagram. A 230v AC supply is provided to the load (in this case, the load is represented with a lamp).

sir,we want automatic street light controller by using timer and counter.we want controlling the street light as follows,day time-6.30a.m to 6 p.m-light off,6.30 p.m to 7.30 p.m-light glows alternately,7.30 p.m to 6 a.m-light on,6 a.m-7 a.m-light glows alternately.So please send related circuit diagram,we are waiting for your circuit diagram.
Automatic LED Street Light Using Electronics LDR Sensor - Electricity DIY Project - Hello Friends, here I will show you how to make LED street lighting using LDR electronics sensor. This is the ...
These energy saving street lights make use of incandescent lamps instead of LEDs.So here I will teach you how to make an electronic circuit for street light automation. The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor.
It senses the light intensity from surroundings and find whether its day or night. And it automatically turns ON when the surrounding is dark and it turns OFF when it receives light from surroundings. A sensor called LDR is used to detect the light intensity.
Automatic Street Light Control Using Light Dependent Resistor (LDR) By Fazlur Rahman - 34 - 4.9 LIGHT EMITING DIODE (LED) A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting.
Summary of LDR circuit for automatic light system: This circuit is based on Light Dependent Resistor (LDR) which 'll turn on LED's when ever darkness is sensed in room. You can put this small lamp in your kid's room as a simple emergency lamp to avoid panic situation in case of sudden power failure.
The complete block diagram of automatic street light control is as shown in Figure-7. The Real time and ON and OFF time is set using keypad and LCD display. A tolerance time of one hour or so is preset control system using light dependent resistor. system.

Dark Sensor ( Light Sensor / Automatic Street Light ): Here is my new simple Electronics project about Automatic Street Light Control System or Dark Sensor. it is a simple and powerful concept, which uses transistor ( BC 547 NPN) as a switch to switch ON and OFF the street light system automaticall...
Automatic dark detector senses darkness. As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1. Dark sensor with variable resistor: A dark detector can be made using a variable resistor. The sensitivity of the circuit can be adjusted with a variable resistor.
When there is low amount of light the light automatically glows and when there is sufficient amount of light it automatically turns off the light. Here based on our room condition the threshold value we took is 100 for the LDR sensor.
