LEDs (12 volts) are often used for tuning cars. They can also be installed to illuminate a small room. Various devices are produced, and they are quite different in brightness. There are many manufacturers on the market. In order to properly connect the LED, you must consider the type of power source. It is also important to evaluate the model parameters. To understand this issue, it is necessary to consider specific circuits for connecting LEDs to 12 V.
Connecting to a low-frequency power supply
At 12 volts, the LED to the low-frequency power supply is connected 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 must not exceed 3.3 ohms. The conductivity of the modulator is also estimated.
If we consider an open type device, then this parameter should be about 20 microns. Also on the market are inexpensive switched modulators. They have very high throughput. However, modulators of this type have several drawbacks. First of all, they have very high energy consumption. It is also important to take into account that the indicator of the color temperature of the device, when used, reaches 700 microns. For 12V LEDs this is quite a lot.
Connecting LEDs to a high-frequency power supply
The 12-volt ultra-bright LED to the high-frequency unit can be connected via a simple relay. In this case, the modulator is selected by an open type. Many experts advise not to use any amplifiers. First of all, they increase the light flux parameter. Thus, the LEDs for lighting (12 volts) quickly overheat. On average, the current conductivity 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 we need to select a trigger. The element can be sold with or without a filter.
Most often, the LEDs (12 volts) are connected in a sequential order. As a result, a ribbon is formed. Modulators are used to adjust the power of the luminous flux. Some experts install expanders with regulators. In any case, the relay is selected for two contacts. It is also important to note that the nominal resistance parameter should not exceed 35 ohms. Before the expander, a pass-through filter is installed. In order to avoid short circuits, an insulator is fixed at the end of the chain. On average, the color temperature parameter should not be more than 500 K.
Parallel connection of LEDs is rare. In order for the lamps not to burn out, a contact modulator is used. If we consider the option with a 12 -volt LED strip , then it is more appropriate to use a pulsed transceiver. In 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 adjust the power of the light 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 the nominal resistance depends on the capacity of the resistor. If we consider the connection with a three-bit trigger, the capacitors are used without an adapter. In this case, the modulator can only be used with a thyristor. Filters for voltage stabilization are rarely installed.
Capacitor Capacitor Circuits
At 12 volts, the LED across the capacitor can only be connected in series. If we consider a circuit with a tape of lamps, the thyristor is used with one adapter. In this case, the filters are applied without winding. In order to avoid short circuits, zener diodes are necessary. They are quite compact. Install them following the filters. The capacitor in this case is fixed to the modulator. A controller is required to adjust the luminous flux. If you select a device of single-pole type, then the nominal resistance parameter will be about 50 Ohm. It is also important to note that the color temperature of the device depends on the conductivity of the controller.
Use of damping capacitors
At 12 volts, the LED through the damping capacitor is allowed to be connected without an amplifier. The trigger in this case is used with one adapter. Many expander experts install without a isolator. If we consider a circuit with a single capacitor, then the modulator is of the open type. Install it through the adapter. If we consider a circuit for two capacitors, then the modulator is of the closed type. It is also important to note that the resistor can only be installed with a regulator. To connect the controller you will need to use a soldering iron. Before switching on the 12 V LED, the overall resistance level of the circuit is checked. The specified parameter must not exceed 35 ohms. If it is larger, then the resistor is selected with a higher power.
The use of absorbing filters
Small LEDs (12 volts) through an absorbing filter are easy to connect. In this case, the modulator is allowed to be installed with different bandwidth. The main advantage of absorbing filters lies in the lowering of the color temperature. As a result, LEDs (12 volts) can work very long. The luminous flux on the average fluctuates around 4 lm. It is also important to note that thyristors are only used for parallel connection. To adjust the power of the light flux, controllers are needed. In the market, they can be found with the cover and without it. 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 only allowed to be connected with an open modulator. In this case, the resistors are of the impulse type. Many experts recommend not using absorbing filters. The transceiver is installed with a bushing insulator. Sometimes the level of nominal resistance can greatly increase in the circuit. To solve the presented problem, you should use mesh filters. In the market they are sold in different sizes. The extender in the circuit is used with two adapters. If we consider a circuit with a flip-flop, then the LED should be installed through an amplifier. Thus, the problem with a sharp increase in the color temperature will be solved.
LEDs (3mm) 12V "Panasonic" are often installed on the machine. Wave transceivers are used to connect the model. They are very compact, it is also important to note that the devices do not require the installation of an additional amplifier. If we consider the circuit for two modulators, then the nominal resistance parameter should be about 40 Ohm. It is also important to pay attention to the current conductivity index. To this end, you need to use the tester. Expanders are often used with one adapter. In this case, the 12 V LED is installed behind the resistor. On average, the nominal resistance should be about 45 ohms.
LEDs (12 volts) for the Philips car are connected via 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 the LEDs (12 volts) for auto are used with the controller. In this case it is important to install an insulator at the beginning of the circuit. Still experts recommend using an absorbing filter. To adjust the light flux of a 12-volt LED you can not do without a high-quality controller. In this case, the resistor is selected one-contact type.
Connecting the LED "Deluxe"
The LED at 12V in the company "Deluxe" has a high color temperature parameter. To ensure that the device does not burn out during prolonged use, open modulators are installed. Recently, models have been produced with pass-through resistors. They are designed to increase the conductivity of the current. However, it is important to note that the indicator of electricity consumption will significantly increase. The expander in front of the 12 V LED is installed with an isolator. Filters are most often used absorbing type. Install them at the beginning of the chain. Many experts check the level of nominal resistance before switching on the LED. It should not be more than 55 Ohm.
