Intelligent High Power Led Street Light Control System Circuit Diagram

Q2 transistor gets a high signal from the collector of q1 and turns on the relay.
Intelligent high power led street light control system circuit diagram. In order to adjust the brightness of the light to achieve energy saving pwm wave was used to change the current for so that the brightness of the led lights change. The relay can be connected similarly as shown in that circuit. So it can control 230v ac lights or similar externally powered lights with the same circuit. The circuit is built around popular op amp ic 741 ic1 14 bit ripple counter cd4060 ic2 scr bt169 bc557 and other components.
Here is a simple street light controller with a switching circuit that overcomes these problems. Relay turned on the ac load that is connected to relay. We have tried this one in this tutorial but you can also try the second one mentioned below. 4 shows the led control circuit diagram.
Ic1 along with ldr1 enables ic2 which drives transistor t1 into conduction. The block diagram of proposed street lights control system is shown in figure 3 a and figure 3 b. Street light controller circuit. Propose an intelligent street light control system based on.
Circuit diagram of automatic street light control. The str eet light controller installed on the street light pole will contr ol led street lighting. For relay interface refer the circuit diagram of the automatic power cut off circuit. Circuit diagram of automatic street light control is given below.
But in this project i have used ldr light dependent resistor. In this project we have used an ldr. Below is the circuit diagram of this light sensing street light. Auto intensity control of power led using arduino.
40 ma and 0 2 w led light was adopted in the lighting module. There are many lights sensors available in market. Automatic street light control system sensor using ldr transistor bc 547 very simple. The transmitter end consists of power supply microcontroller pic 16f photosensitive detection circuit day night sensor infrared vehicle detector feedback circuit fault detection circuit lcd display and mi wi transmitter module.
The proposed control network enables disconnection of the street lighting system from the mains during peak load time reducing its impact in the distributed power system automatically at overload.
