Sensational Led Street Light Circuit Diagram
Leds 1 watt 350 ma cool white.
Led street light circuit diagram. R3 r14 10 ohms 2watt. Circuit diagram and explanation. The above diagram shows a 3v led circuit in this circuit there are two aa cells are used.
For more details visit simple basic led circuit. 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. But in this project i have used ldr light dependent resistor.
Street light or lamp circuit circuit diagram here is a very useful project of an automatic street light or lamp circuit which can be used to activate your outdoor lights like garden lamps night lights etc. Two bc547 npn transistors are used to drive the relay. In the final prototype the leds were mounted on special aluminum based heatsink type pcb it is strongly recommended without which the led life would deteriorate.
Circuit diagram of automatic street light control is. Automatic street lights turn themself on and off automatically by sensing intensity of light with the help of lights sensors. Circuit diagram of automatic street light control.
A minimum value of 390 ohms resistor should be used when operating an led with. Two of the problems commonly associated with street lights are false triggering due to slight variation in the intensity of ambient light and no control over switching action. In this project we have used an ldr light dependent resistor which is responsible for detecting light and darkness.
In fact you can this circuit for implementing any type of automatic night light. Automatically when the sun set and turn off automatically when the sun rises. Circuit diagram for the street light led pwm controller.
