Many LED lamps in stores are sold with switches that have a backlight. In order to understand their connection, it is important to consider the type of switch. Modern models, as a rule, are available with beam transistors. Some switches may also contain regulators. Thus, the user can adjust the lamp power. Adapters to models are designed for 12 and 220, 230 V.
Also , the connection diagram of the lamp may vary depending on the design features of the device. Many manufacturers equip models with special filters, which significantly reduce the energy consumption parameter. In order to understand this issue in more detail, it is necessary to consider in detail lamps for 12, 220 and 230 V.
12V lamps
At 12 V there is often an LED lamp with a switch and a backlight. How to connect it through an adapter? In this case, the capacitor will need an output type. If we consider two-contact switches, then the connection will be carried out in the first phase. In this case, the input voltage parameter can be checked using a tester.
Movable contacts must be connected to a resistor. If we talk about the switch without a damper, then there is no need to use the conversion unit. If we consider lamps of the E27 series, then in them the luminous flux should be at the level of 500 Lm. The indicator of negative resistance in turn should be equal to 7 Ohms. On average, the glow temperature of such lamps is no more than 4000 K. If after connecting the switch to the adapter the lamp blinks, then you need to check the resistor connection. Some manufacturers produce models designed only for lamps with a power of 5 watts.
Connecting lamps to a 220 V network
An LED lamp with a switch and a backlight can be connected to a 220 V network in various ways. Instructions for use of the device will be very useful. First of all, you should consider the option of connecting through the most ordinary trigger. In this case, it is important to untwist the switch. The trigger output contacts are connected in the first phase. Immediately after connecting the transistor, the output voltage in the circuit is immediately checked. On average, it should not exceed 200 V. Next, use an insulator for a capacitor. If we talk about models with a low luminous flux, then thyristors in this situation can not be used.
Through the trigger, the LED lamp with the switch and the backlight turns on quite simply. Connection methods do not end there. You can still consider the option with dinistors. These elements can be found single-phase and two-phase. For normal operation of the lamp should stop on the second option. The adapter is not used in this circuit. However, a beam type transistor is required. Also, if we consider lamps with a large luminous flux parameter, then an additional frequency transistor is used. It is directly connected to the circuit via a switch. In this case, the insulator is important to use a fusible type. Ultimately, the negative resistance in the circuit should not exceed 45 ohms.
230 V lamps
At 230 V, an LED lamp with a switch and a backlight (photo shown below) can be connected to the network via a trigger. In this case, the controller is also allowed to install. If we consider lamps with a luminous flux in the region of 500 Lm, then the adapter should be installed together with a binary capacitor. It connects directly to the diffuser.
It is also possible to connect 230 V lamps through special controllers. In this case, models with resonators are selected that have high sensitivity. To ensure that the output voltage is not large, a filter is used. Find it in the store is very simple. First of all, when connecting, you should deal with the connection of the resonator. Next, the switch is attached and the negative resistance is checked. Lastly, the capacitor is connected to the output contacts of the resonator.
Connection via capacitorless adapter
An LED lamp with a switch (with backlight) is connected through a capacitor-less adapter with a power of less than 6 watts. In this case, the luminous flux should not exceed 400 Lm. Resistors in a circuit are usually used openly type. If we consider models with two-contact switches, then there is no need to install filters. First of all, a high-quality trigger is selected. Then it connects directly to the switch.
The next step is to set the regulator. In this case, the input voltage parameter should not exceed 200 V. If the lamp blinks after connection, it means that its sensitivity is very high. In this situation, many experts recommend still using filters. Adapters in this case are connected only through two-contact conductors. You can also consider using a wave trigger. However, connecting the regulator to the circuit will fail.
Using a modular adapter
Through modular adapters, connecting an LED lamp with a switch and backlight is quite simple. In general, these devices are universal. The lamp for connection is suitable for 6 watts. The luminous flux may exceed 500 Lm. First of all, a switch is installed directly to connect the lamp.
If we talk about three-pin models, then you need to find the zero phase. This can be done with the help of a tester. The next step is to determine the negative resistance in the circuit. It is also important to consider the type of capacitor. If we talk about pulsed models, then the insulator in this case is more appropriate to use a fusible type. You should also consider options with a damper. It connects to modular adapters through a field resistor.
Connecting multiple lamps
In order to connect several lamps to a 220 V network, you can not do without a trigger. The adapter in this situation can easily be used modular type. Two capacitors will be needed for these purposes. It is also important to consider the power of the lamps. If we talk about models at 5 watts, then it is more advisable to select a damper broadband. To install it, a switch is attached in the first place. Next, you need to fix the adapter.
Connecting to a 220 V network is carried out in the second phase. In order to determine it, you will have to use a tester. Next, it is important to connect the capacitors. If the lamp starts blinking after switching on, it means that the negative resistance parameter is very large. In order to normalize it, filters are used.
Lamps with regulators
In the presence of a regulator, an LED lamp with a switch (with backlight) can be connected only through a modular adapter. If we consider circuits with capacitive capacitors, then in this case the models are suitable for 6 watts. It is also important to note that in this case the adapters must be connected directly to the dampers. You can still consider options with diffusers. However, in this situation, for the normal operation of the lamp, a beam transistor will also be required. Directly connecting it through an insulator.
Lamp "Panasonic"
A 7 W LED Panasonic lamp with a switch and a backlight (described in the instructions) is connected to the 220 V network using modular adapters. In this case, various transistors can be used. If we talk about double-contact switches, the diffuser is connected through the first phase. However, before this, the negative resistance in the circuit is mandatory checked.
Also, many experts advise considering the option with triggers. However, they are most suitable for three-pin switches. In this situation, an additional filter is required. First of all, an adapter is prepared for connecting the lamp. The next step is to connect a transistor to it. Further it remains only to use the trigger directly. Filters in this case are prohibited. Otherwise, the negative resistance in the circuit can reach 50 Ohms.
Lamps with Philips switch
LED lamp with a switch (with backlight) "Philips" for 7 W to a 220 V network connects quietly through a capacitor-less adapter. In order to do everything right, transistors with high conductivity are primarily procured. In this case, the damper will need a pulse type. If we talk about double-contact switches, then the lamp can be used with a luminous flux of 400 Lm.
More powerful analogues are not able to work on a network with a capacitor-less adapter. Before starting the installation, the switch is mounted at the resistor. Next, the trigger is connected directly. After that, it remains only to fix the adapter and connect the output contacts.
Connecting a Deluxe Lamp
LED lamp with a switch (with backlight) "Deluxe" with a power of 7 W is connected, as a rule, through a modular adapter. However, it is important to consider that this model uses a capacitor with a large saturation parameter. In order that the negative resistance in the circuit does not drop sharply, special filters are used. Start connecting the lamp to the 220 V network with the installation of switches.
If we consider two-contact modifications, then different types of resistors can be used for them. First of all, you can consider capacitive options. Find such resistors in the store is not difficult. It is also important to note that they are all right with sensitivity. In this case, the capacitor is connected to the switch through the upper contacts. However, before that, the output current parameter is checked.
