After the incandescent lamps appeared, there wasinvented dimmer for LED lamps. Dimmer for LED lamps 220V can replace the switch, it can be installed in a box or embedded in an LED lamp. Buyers quickly enough appreciated the privileges of this device. The main reason for this is the improved functioning of LED light sources at 220V. Due to this, you can change the brightness of the light, the ignition mode, the color gamut of LEDs, smoothness of inclusion. A dimmer is installed for the LED lamps instead of the switch. Its advantages:
favorable lighting at any time of day;
improves the design of the room.
Variety of dimmers
Divided according to the principle of regulation:
Mechanical regulation of light. Brightness can be adjusted with a wheel or a button.
Sensory light control. Quite attractive in appearance. Thanks to the touch screen, it is easy and convenient to operate. For the price it is more expensive.
Thanks to the remote control. This is quite an interesting way, since you can control lighting from anywhere. On the radio channel, you can turn on the light even from the street, and the infrared channel that is familiar to us works on the principle of a remote from the TV.
Adjust light through Wi-fi. Quite expensive and modern type of lighting control at home or apartment, because you need to manage from your phone or tablet. From any corner of the house you can take control of the light. The kit also includes touch panels.
Acoustic. The dimmer operates from a voice command or a loud sound.

According to the version of the installation:
Modular or panel dimmer. The installation is made in a switchboard on a DIN rail. This model offers us a wide range of actions: adjust brightness, come up with a variety of light scenarios, and other functions. Control is carried out thanks to remote buttons, remote controls or system buses.
Dimmer for incandescent lamps or instrumental. This kind of dimmer is very convenient, as it is inserted into the mounting box. Adjustment by light is carried out by the button or the switch.
A monoblock or wall dimmer, which alsois inserted into the back box. The most common and convenient kind of dimmer. To control LED lamps use a special dimmer with PWM or an ordinary dimmer with dimmable LED lamp.
Remote unit. This type is used to connect point lights to a false ceiling.
By the type of control signal, dimmers can be:
By type and power characteristics of lamps:
dimmer for incandescent lamps and halogen lamps in 220V;
Only for halogen lamps, which are fed from the transformer;
for LED and fluorescent lamps.
Principle of operation of a dimmer using PWM
an extensive range in changing the brightness of lamps from 12-220V;
to change the brightness, it is not necessary to increase or decrease the current in the circuit of the LED lamp.
How to combine dimmers and LED lamps
It turns out that not every LED light bulb on the220V is designed to control the brightness of light. Using an uncontrolled light bulb with a dimmer leads to unstable operation of the system. Therefore, it is necessary to determine in advance the need to adjust the brightness of light.
We recommend our article LED Armstrong Lightings.
First, consider what the LED light is:
has a regular base;
operates from an ordinary electrical network in 220V;
the light flux should be similar to ordinary lamps.
In order for the buyer to be able to adjust the brightness of light in a conventional lighting system, the known suppliers necessarily indicate this in the passport on the light bulb or on the package itself:
on the package with the inscription "brightness adjustment";
simply there can be an inscription "dimmable".
The dimmable lamp makes it possible to use ordinary dimmers together with LED lamps, which are cheaper than specialized regulators.

ability to adjust the luminous flux: using the buttons, rotary mode, remote, touch;
the ability to turn off the light in an automatic way;
probability of smooth switching on or switching off the light;
adjust the brightness of light;
the ability to imitate the mode of human presence;
probability of working with a wide voltage range;
probability to remember, at what level the brightness of the lamps is set;
protect against possible overloads and short circuits;
can function at high and low temperature drops.
Installation and installation of dimmer
To install and connect a dimmer, do notbe sure to call the wizard. You can do all this yourself. The device by the way of execution is waybill or built-in, we connect the device in series with the switch. To begin with, use the indicator to determine the phase. Do not forget to de-energize the electrical network. We put the device on a phase wire.
Each of us has often thought abouthis housing and the objects that surround him. And every time the thought came to surround themselves with modern technology. Therefore, to begin to equip their rooms with LED lights and instead of switches to put dimmers-this is the first step to the arrangement of a high-tech home.
