LEDs (12 volts) are often used for tuning cars. They can also be installed to illuminate a small room. Devices of various shapes are available, and in brightness they are quite different. There are many manufacturers on the market. In order to properly connect the LED, the type of power source should be considered. It is also important to evaluate model parameters. To understand this issue, it is necessary to consider specific schemes for connecting LEDs to 12 V.
Connection to the low-frequency power supply unit
At 12 volts, the LED to the low-frequency power supply is connected via 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 modulator conductivity is also evaluated.
If we consider an open type device, then the specified parameter should be about 20 microns. Also on the market are low-cost switched modulators. They have very high bandwidth. However, modulators of this type have several drawbacks. First of all, they have a very high power consumption. It is also important to consider 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
An ultra-bright 12 volt LED can be connected to the high-frequency unit via a simple relay. In this case, the modulator is selected open type. Many experts advise against using any amplifiers. First of all, they increase the luminous flux parameter. Thus, the LEDs for lighting (12 volts) quickly overheat. The average current conductivity should be 25 microns. Before connecting the LED to the network, the parameter of the nominal resistance is checked. Anyone can do this with the help of a tester. On average, the nominal resistance when using an open modulator must 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 sequential order. The result is a tape. Modulators are used to adjust the light output. Some experts install expanders with regulators. In any case, the relay is selected for two contacts. It is also important to note that the parameter of the nominal resistance should not exceed 35 ohms. A filter of the pass type 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 to not burn out, a contact modulator is used. If we consider the option with a 12 V LED strip , then it is more advisable to use a pulsed transceiver. It is sold on the market with a security 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 light flux, it is allowed to use triggers.
If we consider two-bit modifications, then capacitors are used with one adapter. It is also important to note that the level of nominal resistance depends on the bandwidth of the resistor. If we consider the option of connecting 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. Filters for voltage stabilization are rarely installed.
Capacitor Capacitor Circuits
At 12 volts, the LED through the capacitive capacitor is only allowed to be connected in series. If we consider a circuit with a tape of lamps, then the thyristor is used with one adapter. In this case, the filters are applied without winding. In order to avoid cases of short circuit, zener diodes are needed. They are quite compact. Install them follows the filters. The capacitor in this case is fixed on the modulator. A controller is needed to adjust the light output. If you select a device of a single-pole type, then the parameter of the nominal resistance 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 damping capacitors
At 12 volts, the LED through a damping capacitor can be connected without an amplifier. The trigger in this case is used with one adapter. Many experts install an expander without an insulator. If we consider a circuit with a single capacitor, then the modulator is used open type. Install it through the adapter. If we consider a circuit for two capacitors, then in this case the modulator is used closed type. It is also important to note that a resistor may only be installed with a regulator. To connect the controller will have to use a soldering iron. Before turning on the 12 V LED, the overall level of the nominal resistance in 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 absorption filters
Small LEDs (12 volts) through an absorbing filter can be connected quite simply. In this case, the modulator is allowed to be installed with different bandwidths. 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 used only with parallel connection. To control the power of the light flux, controllers are needed. They can be found on the market with and 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 can only be connected with an open modulator. In this case, the resistors are pulse type. Many experts recommend not using absorbent filters. The transceiver is installed with a bushing. Sometimes the level of rated resistance can increase greatly in the circuit. To solve the problem presented, strainers should be used . In the market they are sold in different sizes. The extender in the circuit is used with two adapters. If we consider the circuit with a trigger, then the LED should be installed through the amplifier. Thus, the problem with a sharp increase in color temperature will be solved.
LED "Panasonic"
LEDs (3mm) 12 volts Panasonic often install on cars. To connect the model, wave transceivers are used. 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 a circuit for two modulators, then the parameter of the nominal resistance should be about 40 ohms. It is also important to pay attention to the current conductivity index. For this purpose, you need to use a tester. Extenders are often used with one adapter. In this case, a 12 V LED is installed behind the resistor. On average, the rating of the nominal resistance should be about 45 ohms.
Philips LED
LEDs (12 volts) for Philips cars 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 a car are used with a controller. In this case, it is important to install an insulator at the beginning of the circuit. Experts also recommend the use of an absorption filter. To adjust the luminous flux of the LED to 12 V, you can not do without a quality controller. In this case, the resistor is selected single-contact type.
Connecting a Deluxe LED
The 12 V LED of the company Deluxe has a high color temperature parameter. In order for the device not to burn out after prolonged use, open modulators are installed. Recently, models began to be produced with bushings. They are designed to increase current conductivity. However, it is important to note that the rate of electricity consumption will increase significantly. The expander in front of the 12 V LED is installed with an insulator. Filters are most often used absorbing type. They should be installed at the beginning of the chain. Many experts check the level of nominal resistance before turning on the LED. It should be no more than 55 ohms.
