After doing a lot of research in the field of cheap LED bulbs, I could finally come up with a universal cheap yet reliable circuit that ensures a fail-proof safety to the LED series without involving costly SMPS topology. Here's the finalized design for you all:. You just have to adjust the pot to set the output according to the total forward drop of the LED series string. Meaning, if the total voltage of the LED series is say 3. This will instantly illuminate the LEDs at full brightness and with complete over voltage and over current or surge inrush current protections.

The circuit of a LED bulb explained here is very easy to build and the circuit is very reliable and long lasting. The reasonably smart surge protection feature included in the circuit ensures an ideal shielding of the unit from all electrical power ON surges.

The above design lacks a genuine surge protection feature and therefore could be severely prone to damage in the long run The LEDs in the above discussed LED lamp circuit can be also protected and their life increased by adding a zener diode across the supply lines as shown in the following image.

For other lower number of LED strings, simply reduce the zener value as per the total forward voltage calculation of the LED string. Likewise, by joining 90nos of 1 watt LEDs in the above design you could achieve a 25 watt high bright, highly efficient bulb. Next, these would be comfortably working without a heatsink, so the entire design could be configured into a much compact unit. So all these benefits ultimately makes this 25 watt LED more efficient and cost effective than the traditional approach.

If you require an improved or a confirmed surge control and voltage regulation for the LED bulb, then the following shunt regulator could be applied with the above 3 watt LED design:. Normally LED control circuits are based on buck boost or flyback principles, where the circuit is configured to produce a constant DC for illuminating an LED series.

The above LED control systems have their respective drawbacks and the positives in which the range of operating voltage and the number of LEDs at the output decide the efficiency of the circuit. Other factors like whether the LEDs are included in parallel or series or whether they need to bedimmed or not, also affects the above typologies.

These considerations make these LED control circuits rather dicey and complicated. The circuit explained here employs a different approach and relies on a resonant mode of application.

Though the circuit does not provide direct isolation from the input AC, it has the features of driving many LEDs with current levels as high as mA.

The soft switching process involved in the circuit ensures greater efficiency to the unit. The circuit diagram shows how the IC has been wired up and how its output has been modified for controlling LEDs in place of the usual fluorescent lamp.LED and Resistors are the first few components which are introduced in the starting of Electronics subject in schools.

For building this circuit you only need four things:. You just need to connect positive terminal of LED with the one end of resistor and then connect another end of resistor with the positive terminal of Battery. Then connect the negative terminal of LED with the negative terminal of Battery. This Negative Terminal of Battery is also referred as the Ground.

The whole setup is built on the breadboard as shown above. So the bigger leg is the positive side of the LED and the smaller leg is negative side. Below is the picture for the same:. We can also make the same circuit using two AA size 1.

Resistor is very important component here, if you connect LED to the Battery without any resistor, then your LED will burn immediately. Some LEDs have more or less current consumption according to their colors and ratings, but here we are explaining this in general. So here we can calculate the resistor value by using the basic OHM law which states:.

So according to the formulae:. So the remaining voltage 9 - 2. You can also calculate the resistance value by using this LED resistor calculator. These current and voltage values are not exact and can be vary according to the Battery capacity and LED. But generally you can use or ohm resistor with any LED, or you can also use 1k resistor if the proper values are not available.

They are still expensive, but that is bound to change. You can make a very good solid-state pocket torch using a few of these white LEDs.

The simplest approach is naturally to use a separate series resistor for each LED, which has an operating voltage of around 3. Depending on the value of the supply voltage, quite a bit of power will be lost in the resistors. The converter shown here generates a voltage that is high enough to allow ten LEDs to be connected in series.

In addition, this converter supplies a constant current instead of a constant voltage. This voltage is compared inside the IC to a 1. The value of the inductor is not critical; it can vary by plus or minus 50 percent. Almost any type of Schottky diode can also be used, as long as it can handle at least 1 A at 50 V. If the LED chain is opened during experiments, the voltage can rise to a value that the IC will not appreciate. Your email address will not be published.

Tags: converter led newport.In this project, we will build few simple LED Circuits. Nowadays, people are investing more in LEDs due to their energy efficiency. Home lighting, office lighting, Automobile lighting, Street lighting etc.

Students, hobbyists and makers often work with LEDs in different types of projects. LEDs are very sensitive components with respect to voltage and current and they must be provided with rated current and voltage values. Wrong voltage or current to LED will burn them off.

But as the complexity of the circuit increases, choosing the right resistor with right wattage is important. The circuit diagram for this circuit is shown below. The following image shows the setup of single LED connected to a 12V Supply and a current limiting series resistor.

The important component other than the LED of course is the Resistor. So, selecting the right resistor with the right wattage is very important. First, we will calculate the resistance.

The value of the series resistor can be calculated using the following formula. Substituting these values in the above equation, we can calculate the value of Series Resistance as.

Now that we have calculated the resistance of the series resistor, the next step is to calculate the power rating of this resistor. Power Rating of a Resistor specifies the value of power that a resistor can safely dissipate.

The Power Rating of a Resistor can be calculated using the following formula. Here, V RES is the voltage drop across the resistor and.

So, the Voltage Drop across the Series Resistor is. The current through the Resistor is same as the current through the LED as they are series. So, the current through the Series Resistor is. Substituting these values in the above formula, we get the power dissipated by the resistor.

Once the right resistor is selected, we can connect the resistor in series and give the 12V Supply to the LED. The following image shows the circuit diagram of the LEDs in Series. Since the LEDs are connected in Series, the current through all of them will be the same i. Coming to the power rating of the resistor, it is equal to 1.Generally, we have two ways of designing the LED Driver: using a Switching mode power supply or a regular transformer based linear regulator.

You need to be very careful when working on AC Supply. Warning: Designing Transformer less power supply without the knowledge of how the components work can be fatal.

It is a metal film capacitor that is often used as a safety capacitor. An X — Rated capacitor is placed between the line and neutral. If this capacitor fails due to overvoltage, the fail will be short and the excess current will blow the fuse and hence avoiding any electrical shocks.

First, the main supply is given to the metal film capacitor. The other end of the capacitor is connected to the AC input of a bridge rectifier. The rectified output is given to a capacitor C2. The Resistor R1 will act as a bleeder resistor it will discharge the capacitor in the event of power failure or if LED fails. Assemble all the components as per the layout and solder them. LEDs need very less current in order to work.

Normally, in a regular transformer based regulated power supply, we will regulate control the current with the help of series resistors. But in the transformer less power supply, the current is controlled or limited by the X — Rated Capacitor.

Since this capacitor is connected in series with the AC Supply, the total current available in the circuit is limited by the reactance of the capacitor. The reactance of a capacitor can be calculated using the following formula:. In our case, we have used a 1. Hence, the reactance of this capacitor is. Now, the current limited AC is given to the Bridge Rectifier. The output of the bridge will be V DC. This is given to a filter capacitor of rating 35V. But the peak to peak ripple voltage across the Capacitor C2 is around 44V.

As far as the power is concerned, the total power output by the LEDs is around 4W.A wiring diagram is a type of schematic which uses abstract pictorial icons to reveal all the interconnections of parts in a system.

Electrical wiring layouts are made up of two things: signs that represent the elements in the circuit, and also lines that stand for the links between them. Electrical wiring diagrams primarily reveals the physical position of elements and connections in the built circuit, but not necessarily in reasoning order. It emphasizes on the format of the cords.

Schematics stress on exactly how circuits function rationally. To review a wiring diagram, initially you need to understand exactly what essential elements are included in a wiring diagram, and also which photographic icons are made use of to represent them. The usual components in a wiring diagram are ground, power supply, wire as well as connection, outcome tools, buttons, resistors, reasoning entrance, lights, etc.

A line stands for a wire. Cables are made use of to link the elements with each other. All points along the cord equal and linked. Cables on some areas should go across each other, but that does not necessarily suggest that they attach. A black dot is utilized to show the injunction of 2 lines. Key lines are represented by L1, L2, and so on. Usually various shades are used to distinguish the wires. There need to be a legend on the wiring diagram to tell you what each color indicates.

Usually circuits with even more than 2 parts have 2 fundamental kinds of connections: series and parallel. A series circuit is a circuit where elements are linked along a single course, so the current circulations through one component to obtain to the following one.

In a series circuit, voltages accumulate for all parts attached in the circuit, and also currents coincide via all components. In an identical circuit, each device is straight attached to the power resource, so each device obtains the exact same voltage. The existing in a parallel circuit flows along each identical branch as well as re-combines when the branches meet again. A great wiring diagram has to be technically correct as well as clear to check out.

Care for every information. For instance, the representation should show the correct instructions of the favorable and also adverse terminals of each component. Make use of the appropriate icons.
