What is street light circuit?
Street light circuit. The circuit uses a Light Dependent Resistor (LDR) to sense the light . When there is light the resistance of LDR will be low. So the voltage drop across POT R2 will be high. This keeps the transistor Q1 ON. The collector of Q1(BC107) is coupled to base of Q2(SL100).
How do you make an automatic street light project?

How does automatic street light circuit works?
A high-intensity discharge lamp emits light by an arc of electricity created between two electrodes. The electrodes are in a transparent tube filled with gas and metal salts. The electrical arc generates heat, which works with the gas and metal to create light-emitting plasma.
Which diode is used in street light?
light-emitting diode
Unsourced material may be challenged and removed. An LED street light or road light is an integrated light-emitting diode (LED) light fixture that is used for street lighting.
How LDR is used in street lights?
Street lights are designed to switch on automatically when it is dark and switch off when there is light so as to save energy. A common device used is called a light dependent resistor (LDR). It is a resistor with resistance that changes according to the amount of light falling on it.
Which mirror is used in street lights?
convex mirror
A plane mirror is used in a microscope, mirror tiles, for signaling and periscopes. Hence, comparing all the given options, it can be concluded option B is correct; a street light bulb uses the convex mirror as reflectors.
How do the street lights turn on?
In a modern streetlight, a small circuit replaces the bird and turns the light on when the amount of light falls below a certain threshold. If a small amount of current flows from emitter to base, then a large amount of current can flow from emitter to collector.
What is the aim of automatic street light?
The main purpose of this project “automatic street light control with different light intensity” is to minimize the cost & loss of electricity and also man power to manually on- off the street light.
Why is LDR used in street lights?
Is concave mirror used in street lights?
Convex mirror are used as reflector in street lamps whereas concave mirror is used as a reflector in torch and car headlight.
Which is part of the automatic street light project?
The key components of the Automatic Street Light Project are LDR, LM358 Op-Amp IC, BC547 transistor, and Relay. The LDR is used to detect the Dark and Light of the surrounding. The LM358 Op-Amp IC compares the LDR output in Dark and Light conditions and produces an output voltage.
What kind of resistor does a street light controller use?
LDR (Light depending resistor), whose resistance is based upon the quantity of the light falling on it, is the main component for sensing the light. Along with these, a few more components are also used. Circuit Diagram of Automatic Street Light Controller Switch Circuit Components used in this Circuit
How are LDR and relay used in street lights?
Automatic Street Light Circuit Using Relay and LDR You have seen street light which automatically gets turned on in the night and gets turned off in the morning or day time, there are sensors who senses the light and control the light accordingly. These Street lights are an important project in smart cities.
