LEDs (12 volts) are often used for car tuning. They can also be installed to illuminate a small room. Devices of various shapes are produced, and they differ quite a lot in brightness. There are many manufacturers on the market. In order to connect the LED correctly, the type of power source must be taken into account. It is also important to evaluate the parameters of the model. To understand this issue, it is necessary to consider specific wiring diagrams for 12 V LEDs.
Connecting to a low-frequency power supply
At 12 volts, the LED is connected to a low-frequency power supply through a selective resistor. Modulators are used to adjust the luminous flux. Some experts recommend checking the nominal resistance in the circuit before connecting the LED. The specified parameter should not exceed 3.3 ohms. The conductivity of the modulator is also evaluated.
If we consider an open type device, then the specified parameter should be about 20 microns. There are also inexpensiveswitched modulators. They have very high throughput. However, modulators of this type have several disadvantages. First of all, they have a very high power consumption. It is also important to consider that the color temperature of the device when using them reaches 700 microns. For 12V LEDs, this is quite a lot.
Connecting LEDs to a high-frequency power supply
A super-bright 12 volt LED can be connected to a high-frequency unit through a simple relay. In this case, the modulator is selected open type. Many experts advise not to use any amplifiers. First of all, they increase the luminous flux parameter. Thus, LEDs for lighting (12 volts) quickly overheat. On average, the current conductivity indicator should be 25 microns. Before connecting the LED to the network, the nominal resistance parameter is checked. Anyone can do this with a tester. On average, the nominal resistance when using an open modulator should be no more than 4 ohms. If we consider circuits with a large number of LEDs, then in this case you need to select a trigger. The specified item may be sold with or without a filter.
Serial connection
Most often, LEDs (12 volts) are connected in series. The result is a ribbon. Modulators are used to adjust the power of the luminous flux. Some specialists install expanders with regulators. In any case, the relay is selectedfor two contacts. It is also important to note that the nominal resistance parameter should not exceed 35 ohms. A pass type filter is installed in front of the expander. In order to avoid short circuits, an insulator is fixed at the end of the circuit. On average, the color temperature parameter should be no more than 500 K.
Parallel connection
Parallel connection of LEDs is quite rare. In order for the lamps not to burn out, a contact modulator is used. If we consider the option with a 12 V LED strip, then it is more expedient to use a pulse transceiver. On the market, it is sold with a protection system. On average, the current conductivity parameter does not exceed 30 microns. Amplifiers for connection are rarely used. In order to regulate the power of the luminous flux, it is allowed to use triggers.
If we consider two-digit modifications, then capacitors are used with one adapter. It is also important to note that the level of nominal resistance depends on the capacity of the resistor. If we consider the connection option with a three-digit trigger, then the capacitors are used without an adapter. In this case, the modulator may only be used with a thyristor. Voltage stabilization filters are rarely installed.
Capacitor circuits
On a 12 volt LED through a capacitive capacitor, it is allowed to connect only in series. If we consider a circuit with a lamp strip, then the thyristor is used with one adapter. In thisIn this case, the filters are applied without winding. In order to avoid cases of short circuits, zener diodes are needed. They are quite compact. They should be installed after the filters. The capacitor in this case is fixed on the modulator. A controller is required to adjust the luminous flux. If you select a single-pole type device, then the nominal resistance parameter will be about 50 ohms. It is also important to note that the color temperature of the device depends on the conductivity of the controller.
Using snubber capacitors
It is allowed to connect a 12 volt LED through a damping capacitor without an amplifier. The trigger in this case is used with one adapter. Many experts install the expander without an insulator. If we consider a circuit with one capacitor, then the modulator is used in an open type. It should be installed through an adapter. If we consider a circuit for two capacitors, then in this case the modulator is used as a closed type. It is also important to note that the resistor can only be installed with a regulator. To connect the controller, you will have to use a soldering iron. Before turning on the 12V LED, the overall nominal resistance level in the circuit is checked. The specified parameter should not exceed 35 ohms. If it is larger, then the resistor is selected with a higher power.
Using absorbing filters
Small LEDs (12 volts) are quite easy to connect through an absorbing filter. In this case, the modulatorIt is allowed to install with different throughput. The main advantage of absorbing filters lies in lowering the color temperature. As a result, LEDs (12 volts) are able to work for a very long time. The luminous flux fluctuates on average around 4 lm. It is also important to note that thyristors are only used when connected in parallel. Controllers are needed to adjust the power of the luminous flux. They can be found on the market with or without lining. There are also other types that include tetrodes. In this case, they should not be considered.
LEDs with wave receivers
At 12 volts, the LED through the wave receiver is allowed to be connected only with an open modulator. In this case, resistors are used pulse type. Many experts recommend against the use of absorbing filters. The transceiver is installed with a bushing. Sometimes the level of nominal resistance can be greatly increased in the circuit. To solve the presented problem, mesh filters should be used. On the market, they are sold in different sizes. The expander in the circuit is used with two adapters. If we consider a circuit with a trigger, then the LED should be installed through an amplifier. This will solve the problem with a sharp increase in color temperature.
LED "Panasonic"
LEDs (3mm) 12 volt "Panasonic" are often installed on cars. Wave transceivers are used to connect the model. They are very compact, it is also important to notethat the devices do not require the installation of an additional amplifier. If we consider a circuit for two modulators, then the nominal resistance parameter should be about 40 ohms. It is also important to pay attention to the current conductivity indicator. For this purpose, you need to use the tester. Expanders are often used with a single adapter. In this case, a 12V LED is installed behind the resistor. On average, the nominal resistance should be about 45 ohms.
LED "Philips"
LEDs (12 volts) for Philips cars are connected through an open modulator. The color temperature of the model is 300 K. On average, the luminous flux of the device does not exceed 450 lm. If we consider a circuit with a conventional modulator, then LEDs (12 volts) for cars are used with a controller. In this case, it is important to install an insulator at the beginning of the circuit. Experts also recommend using an absorbing filter. To adjust the luminous flux of a 12 V LED, you cannot do without a high-quality controller. In this case, the resistor is selected as a single-pin type.
Connecting the Deluxe LED
LED for 12 V of the company "Deluxe" has a high color temperature parameter. In order for the device not to burn out during prolonged use, open modulators are installed. Recently, models began to be produced with pass-through resistors. They are designed to increase current conductivity. However, it is important to note that consumptionelectricity will increase significantly. The expander in front of the 12 V LED is installed with an insulator. Filters are most often used of the absorbing type. They should be installed at the beginning of the chain. Many experts check the nominal resistance level before turning on the LED. It should be no more than 55 ohms.
