Unique Street Light Circuit Diagram
Street light controller circuit.
Street light circuit diagram. Ic2 is also used to trigger scr1 to switch on the street light. Ic1 along with ldr1 enables ic2 which drives transistor t1 into conduction. The positive side of the battery is divided into two directions.
The circuit is built around popular op amp ic 741 ic1 14 bit ripple counter cd4060 ic2 scr bt169 bc557 and other components. At first direction there is a resistor of 330 ω and on the other direction 220 ω resistor is connected. Street light or lamp circuit circuit diagram.
This circuit is same as a dark detector or light detector circuit only here we have replaced simple led with a ac load using a relay. In this project we have used an ldr light dependent resistor which is responsible for detecting light and darkness. T he circuit diagram present here is that of a street light that automatically switches on when the night falls and turns off when the sun rises.
Removal of trigger turns the light off street light controller with a switching. Three light emitting diodes are used this. Don t worry about negative side and the positive side of the resistor.
The circuit is quite sensitive and versatile and can be used. When intensity of lights falls below minimum level. Resistor is not polarity sensitive.
This is very simple circuit with few electronics components. Ldr light dependent resistor is used to sense intensity of light. Let try to understand this circuit.
