Home >> led solar street light circuit diagram and symbols examples
Some LED circuits explained examples from various projects: flashing LEDs, 220V LEDs and more. We start by showing you the LED circuit in series with a resistor. You must make some calculations to figure out the resistor value, depending on voltage power supply, LED voltage drop and desired current.
Automatic street light control circuit diagram, In this article I am going to post a very simple circuit diagram of automatic street light control using transistor and light dependent resistors. This is a very simple circuit of automatic street light control.

Figure shows a great project / schematic of a 12V solar LED night activated lamp circuit. This is a versatile project and can be used for variety of purposes. For example you can use it as a great automatic solar garden light and this can be done easily by expending each three LEDs in a lamp in
Light Emitting Diode (LED) Created on: 30 July 2012. The LED (Light Emitting Diode) is exactly what it name suggests – a diode that emits light. LEDs are like small light bulbs and are available in different sizes and colours. Some examples of LEDs: LED Symbol. The symbol for an LED used in circuit diagrams is shown here: LED Polarity
Device in solar LED street light system The solar street lighting system consists of many sections. In this chapter, only the Solar panel, the Battery, the Controller and the Led lights are briefly introduced. 2.1 Solar panel 2.1.1 Working principle The Photovoltaic (PV) cell is composed of at least two layers of the semiconductors
As can be seen in the given circuit diagram, the design basically consists of a solar panel, a PNP transistor, few LEDs, a battery and a few resistors. The transistor is the only active component which is positioned as a switch for preventing the battery voltage from reaching the connected LEDs during day time.
Hopefully those looking for practical information on electrical circuits and wiring LED components found this guide first. It's likely though, you've already read the Wikipedia page about Series and parallel circuits here, maybe a few other Google search results on the subject and are still unclear or wanting more specific information as it pertains to LEDs.

The main aim of this project is to develop LED based street lights with auto intensity control system by using Arduino board and solar power from photovoltaic cells.
Because, this solar powered street light can conserve a large amount of electricity compared to the other lights which are a light to their maximum intensity at all times after they are turned on Solar Powered Led Street Light with Auto Intensity Control Circuit and Its Working.
Circuit 3 of Simple LED Circuits (LEDs in Parallel) The final circuit in the simple LED Circuits tutorial is LEDs in Parallel. In this circuit, we will try to connect three 5mm White LEDs in parallel and light them up using a 12V Supply. The Circuit Diagram for LEDs in Parallel Connection is shown in the following image.

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.
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.
To see that the current of LED is very high. When we use the 12V 2.5Ah battery, works just 8 hours only. It should be set to a light sensor, to control LED brightness, when less light only. For example LED lights at approximately 19.00 to 5.00. I designed the automatic light switch, as Figure 4 the complete schematic circuit diagram. Figure 4
