DIY LED turn signals

Right now you can see how many people are changing their car lighting from incandescent lamps to LED lamps, which in some cases are brighter, less energy-consuming, and much more durable than lamps. Let’s not ignore the turn signal indicators using the example for the VAZ 2101-07 car. And we’ll look at how to do it in more detail below.

About the design:

The lamps are placed flat on the board, regardless of the fact that the repeater itself has a slightly prismatic shape.

We draw a printed circuit board, transfer it to single-sided foil PCB, and etch it. Look at the photo to see what happened.

We use a Dremel to make grooves for the insert or wires; in our case, we use a PCB leg.

This is what the assembled structure should have looked like. When I finished the prototyping, I started soldering.

And we test by connecting the power.

And we try on our body.

As you can see, everything fell into place perfectly. The diodes are offset from the edge by a couple of millimeters, and the repeater body, as you remember, has beveled planes from the center.

The result can be seen in the very first photo. Happy assembly.

When using LEDs, do not forget to calculate the voltage and the required resistance of the resistor(s).

Quite often, car owners strive to decorate them in a special way. One possible solution to this problem is the use of LED turn signals. In addition to this application, this semiconductor element can be used in car lighting, exterior design (for example, side lights).

Some go even further and install them inside the cabin to express more individuality. One example of such use would be at a door. When stopped, they turn on, the driver or passenger can easily leave the vehicle.

Types of LEDs

An LED is a semiconductor radio component that begins to glow when exposed to electric current. The main element in them is silicon. Depending on the type of dopant used in this semiconductor element, the LED can change its light.

The most commonly used types of such microelectronic components are:

1. Aluminum, gallium, and nitrogen are used as impurities. Depending on the concentration, the color range varies from blue to green.
2. Based on indium, helium, phosphorus. Color can range from red to yellow.

Today, the semiconductor industry produces LEDs in all possible colors. Therefore, there are no problems with this.

One LED is unlikely to be able to illuminate the turn signal, but several can easily cope with this task

Based on power, they are divided into low-power and high-power. Power ones are designed for a current of more than 0.35 A. In turn, low-power ones operate up to this value.

Possible connection diagrams

Today, the most commonly used LEDs are:

1. A similar connection is used to switch a long chain of LEDs (for example, along the perimeter of a car). A capacitor-type power supply is used as a voltage source. The current-limiting element in such a circuit is a capacitor. A diode bridge in combination with a filter (usually a set of resistor and capacitor) is used as an AC-to-DC converter. Be sure to install a protective resistor in series with the diode chain, which takes over the excess voltage.
2. The second option is to connect LEDs into garlands of 3-6 pieces in series. Several such garlands can be connected in parallel to each other, depending on the power source. The role of the latter in this circuit is played by a stabilized power supply with a voltage of 12-24V. In such a circuit, it is also necessary to install a protective resistor in series with each garland.
3. The last, third connection option is direct. In such a circuit, only a power diode can operate, which is designed for a current of more than 0.35A.

The LED has only two legs for connection - anode and cathode. The anode must be connected only to the positive pole of the power source. In turn, the cathode is to negative. If connected differently, this semiconductor element will not work.

Requirements for the performer and instrument

When carrying out any electronic installation, a tester (for taking measurements), a soldering iron, tweezers, and side cutters must be used (if these are not available, you can use pliers, which can also perform this task). To perform calculations and determine the required values, you will need a calculator. Consumable materials include fiberglass (a printed circuit board is made from it - the base for attaching this semiconductor element), solder, rosin, soldering flux and tsaponlak.

It will be difficult to make LED turn signals without a tester

Selection of the most suitable series of elements

The main parameters of any device in this series are the rated voltage. That is, the operating values ​​of these parameters at which the LED retains its original properties. The calculation is made according to Ohm's law for a section of the circuit. Each car has a current source with specified parameters - current and voltage. On the other hand, we have the characteristics of the required LED. The difference between the first and second values ​​will be the characteristics of the resistor that must be connected in series in the circuit. And knowing the parameters of the latter, the entire circuit can be assembled without much difficulty.

Let's carry out the calculation for the simplest circuit, which consists of a stabilized voltage source, an LED and a protective resistor. In other cases, the technique remains almost the same, but only due to the larger number of elements used, the calculation becomes more complicated.

For example, in a car there is a source whose values ​​are respectively 0.02A and 24V. Moreover, a constant voltage source (for example, a battery). The LED needs to receive 0.02A and 2V. Now we determine the value of the potential drop across the resistor:

UR= Upit-Ud,

where UR is the potential drop across the resistor, V

Upit – power source voltage, V

Ud – nominal (operating) potential drop across the diode, V

Using the formula given earlier, we get UR=24-2=22V. All elements of this circuit are connected to each other in series. As a result, the current does not branch off anywhere; at any point in the circuit it will be equal to 0.02A. As a result, we obtain the value of the resistor resistance according to Ohm’s law:

where R is the resistor resistance, Ohm

IR – current in the circuit, A

Substituting the necessary values, we get R=22/0.02=1100 Ohm. Next, we determine the second most important parameter of any resistor - power. It is determined by the formula:

The result is PR = 0.02 * 22 = 0.44 W. From the existing series of resistors, we select the nearest largest values ​​- 1.1 kOhm and 0.5 W. At this point the calculation can be considered complete - the parameters of all elements of the electrical circuit have been determined.

One example of using LEDs

One of the most common uses of these elements in cars is as a . Now let's look at how to make LED turn signals from regular ones.

The procedure is as follows:

1. The most suitable connection scheme is selected
2. The required LED is selected
3. Next, all other radio components of the electrical circuit are calculated
4. Based on the calculations performed, protective resistors and other components are selected
5. Then a list of necessary radio components is compiled. With this list, you need to visit the nearest store of this profile and buy all the necessary equipment there.
6. All necessary documentation is being developed (including a drawing of the printed circuit board and its installation drawing)
7. Then you need to make a printed circuit board to mount radio components on it. To do this, a pre-designed pattern is applied to the fiberglass board using varnish. All necessary holes for mounting radio components are drilled. She is immersed in ferric chloride. After the design on the board is etched, it is removed. Wash with plain water. Then the protective layer is removed using a solvent. The next step is rinsing again with running water. And only after that it dries. Upon completion of all completed procedures, we receive a ready-made board for further work. Since there are only 4 turn signals, 4 boards must also be made.
8. At the next stage, based on the diagram and the developed board drawing, all elements of the circuit are installed. Upon completion of assembly, all contacts must be opened with tsaponlak (it will provide the necessary insulation and protection of the circuit in case of moisture getting here)

1. Then you need to dismantle the old turn signals and carefully disassemble them. And in such a way as not to damage it.
2. The old lighting element (lamp) is completely turned off and removed.
3. The joints where everything was previously filled with glue must be cleaned using a needle file and sandpaper. Then this joint is degreased with alcohol. Then all this is washed with water and should dry.
4. New lighting elements are installed in place of the old lighting element. If necessary, minor design changes can be made to simplify the installation process.
5. Then reassemble in reverse order. It is necessary to apply glue to the joint and glue the disassembled turn signal. Then you need to wait until the glue hardens. In the future, this turn signal is installed in the old place and the old wires are connected to it.
6. The next step is to make changes to the . To do this, the old wires are broken and an additional stabilized power source is wedged into it (you can purchase it separately or make it yourself). Moreover, its output is set to an LED. The input is supplied with voltage from the contact group of the intermediate relay. It is most convenient to place this element in the dashboard of a car. At the final stage, you need to check the polarity of the connection visually. The anode must be connected only to the positive pole of the power source. In turn, the cathode is to negative. If connected differently, this semiconductor element will not work and may even fail.
7. Then it is necessary to inspect the assembled circuit and compare it with the initial version for compliance.
8. Next, power is supplied and the functionality of the circuit is checked. If everything is fine, then the installation is complete. Otherwise, it is necessary to find the cause of the malfunction and eliminate it.

LED lamps are semiconductor elements that glow when exposed to electric current. The main element in them is silicon. Depending on what impurities are used, the color of the light bulbs changes.

Tools and materials

To make a running turn signal with your own hands, you will need the following tools:

• soldering iron;
• side cutters or pliers;
• soldering iron and soldering material;
• tester.

You need to prepare fiberglass laminate from consumables. It is needed for the manufacture of a printed circuit board on which the semiconductor element will be placed. The required LEDs are selected. Depending on the characteristics of the LEDs and the current and voltage values ​​of the on-board network, the characteristics of the protective resistors are calculated. Using calculations, the remaining components of the network are selected (the author of the video is Evgeny Zadvornov).

Work sequence

Before making turn signals, you need to choose a suitable scheme.

Then, based on the diagram, make a printed circuit board and apply markings on it to place future elements.

The assembly consists of a sequence of actions:

1. First, you should turn off the power to the car by disconnecting the negative terminal from the battery.
2. Next, you need to remove the old turn signals and carefully disassemble them.
3. Old light bulbs should be unscrewed.
4. The joints should be cleaned of glue, degreased, washed and allowed to dry.
5. In place of each old element, a new running light turn signal is installed.
6. Next, assembly and installation of the lights is done in the reverse order.
7. After installation, the wires are connected.

At the next stage, an additional stabilized power source is connected to the network. Its input receives power from the intermediate relay, and the output is connected to a diode. It is better to place it in the instrument panel.

When connecting LEDs, you must ensure that the anode is connected to the plus of the power source, and the cathode to the minus. If the connection is not made correctly, the semiconductor elements will not light up and may even burn out.

Features of installation and configuration of running direction indicators

You can install dynamic turn signals instead of conventional LEDs. To do this, the board with LEDs and current-limiting resistors is removed and dismantled. On the repeater you need to tear the glass away from the body. Then you should carefully cut out the reflector and remove it.

In place of the remote reflector, an SMD 5730 board is installed, on which yellow LEDs are located. Since the repeater has a curved shape, the board will have to be delaminated and bent a little. You need to cut off the part with the connector from the old board and solder it to connect the controller. Then all components are returned to their place.

To adjust the timing of the running LED lights, a switch is soldered to the microcontroller. When a suitable speed is found, jumpers are soldered in place of the switch. When connecting two pins to ground, the minimum time between LED flashes will be 20 ms. When the contacts are closed, this time will be 30 ms.

Price issue

You can make a running light turn signal from daytime running lights. Their cost is 600 rubles. In this case, you can use “pixel” RGB LEDs as light sources in the amount of 7 pieces for each running turn signal. The cost of one element is 19 rubles. To control the LEDs, you need to purchase an Arduino UNO costing 250 rubles. Thus, the total cost will be 1060 rubles.
