Dimmable luminaires

Smoothly increasing or decreasing light using a special device is called dimming. Not all lighting devices are suitable for installation in such networks. This problem does not exist with incandescent and halogen lamps, and LED lamps are not dimmable in all cases - this is their only, albeit relative, disadvantage. Therefore, when choosing lamps, you need to find out whether this model will work in tandem with a dimmer.

As for the dimmers themselves, there are 2 ways to purchase them:
Buy a lamp, floor lamp, table lamp with a built-in device;
Buy only a dimmer.

Dimmed LED lamps are not afraid of strong surges in mains voltage, this is another of their significant advantages. Outwardly, they are similar to ordinary diodes - all the differences are hidden inside. Employees of offices, warehouses, and other facilities do not require special skills to use the lamps. Workers can set the intensity themselves. You can control the devices using the included remote control or use a Wi-Fi network for this.

Dimmers for LEDs

Dimmable LED lights use special dimmers. Their design and dimming technology are slightly different from devices connected to incandescent lamps: in this case, the brightness of the glow changes due to an increase or decrease in the current passing through the device. If you use such a device with a conventional LED, the efficiency and color of the glow will drop sharply.

The mechanism of operation of LED dimmers is expressed in the supply of constant current pulses to the LED. The amplitude value is equal to the optimal current level. The brightness of the light depends on the width of the pulses. To achieve an even glow that eliminates the flickering effect, pulses are supplied at a high frequency, which can reach 300 kHz. It is not always convenient to use devices dimmable by your own control systems. The modules inside the system have to be divided into 3 parts, which include the light sources themselves, the power supply with the control system. Personnel must be provided with access to flow control, which further complicates the structure and ultimately increases costs.

The most acceptable and convenient option is the introduction of special dimmable LED lamps into a traditional 220 V AC network. The devices are controlled by publicly available dimmers designed for connection to incandescent lamps.

Advantages of dimmers

Economical energy consumption is the first and main advantage of dimmable lamps and the dimmers themselves. A high-tech control system allows you to set the light to maximum saving mode, and do this in the entire illuminated area, in part of it, or in all rooms in the enterprise. Already economical LEDs will consume even less electricity. This fact all the more needs to be taken into account during a period of significant growth in energy prices.

Other advantages of dimmable lamps:
Installation of lamps and devices is carried out in an already operating network; there is no need to upgrade or add other components;
Wide range of models for installation on residential, commercial and industrial sites;
A significant reduction in energy consumption makes it possible to increase the number of luminaires connected to one network by approximately 10 times;
Wide range of lighting brightness;
Simple and intuitive control - you can do without installing an additional low-current line and complex controllers;
LED lighting can be combined with natural light to maintain lighting at the desired level.

The scope of application of dimmable diodes is much wider than that of incandescent lamps. The intensity of the luminous flux can be changed over a wide range (from 0 to 100%, for comparison: for incandescent and halogen lamps the minimum indicator starts at 10%, although in both cases lighting at the lower values is used extremely rarely, and the zero indicator is achieved purely theoretically), without affecting color temperature. This property, as well as the absence of a flickering effect with the ability to save tens of thousands of rubles annually on electricity costs, makes dimmable LEDs one of the most suitable types of lighting in the residential, commercial, industrial sector, as well as in the design of professional lighting and photography.

Previously, room lighting was controlled by a rheostat. A significant drawback of these devices was their high power consumption, regardless of brightness. At minimum lamp power, electricity was consumed in the same amount as at maximum, since most of it heated the rheostat.

Adjusting the lighting in the room

Advantages and disadvantages

Nowadays, an electrical load regulator (dimmer) can be bought at an electrical goods store. It is mainly used to change the brightness of lamps of different types and has the following advantages:

change in lamp intensity;
setting automatic brightness change Automatic light dimmer using a timer;
remote control;
used as a switch and to set lamp glow modes: smooth change, creation of light patterns, blinking;
increasing the durability of lamps due to soft starting;
saving energy consumption.

Regulators have disadvantages:

extraneous interference interferes with the operation of devices that do not have filters;
generation of interference for other devices receiving radio signals;
not all devices save energy;

Dimmer Types

The simplest device with adjustment has a switch and a rotatable knob. The brightness of the regulator depends on the position of the potentiometer. The dimmer is suitable for controlling incandescent and halogen lamps. In terms of power, it is selected at least 15% higher than the connected maximum load. It must have built-in short circuit protection. The simplest option is a fuse.

Dimmer comes in the following types:

Overhead. Most often it contains an auxiliary rheostat and is used for LED strips.
Passage - for large areas of premises.
Two- and multi-channel – selected by the number of lamps and control modes.

Where should you not install dimmers?

In public places where frequent use will not allow them to perform their basic functions. Everywhere you can install devices for smooth switching of lamps built into switches, which can increase their service life.
In places where there is no certainty regarding the installation of lamps.

Methods of regulation

Mechanical - turn the handle. First, the dimmer is turned on until it clicks, and then the brightness is set. The turn-and-press device is more convenient, since you can use a switch with constant adjustment of the regulator.
Electronic: push-button, keyboard. Can be used as a switch and regulator.
Touch - the control panel implements many different functions.
Remote – control via radio signal or using an IR remote control.

Types of lamps for dimmers

Incandescent and halogen lamps 220V. To change the light intensity, any dimmers can be used, since the load is only active (does not have inductance or capacitance). The disadvantage is that the spectrum shifts towards red as the voltage decreases. The power limit for dimmers is 60-600 W.
Low voltage halogen lamps. For them, we can use a step-down winding transformer, which requires a regulator capable of operating with an inductive load. It is marked RL. When using an electronic transformer, capacitive loads are installed.

Halogen lamps require a smooth change in voltage, which increases their service life. The latest models determine the type of load and adapt to it, changing the control algorithm. You can simultaneously regulate different groups of lamps: incandescent and halogen.

Fluorescent lamps. If they are started via a switch, a glow starter and an electromagnetic choke, a conventional dimmer and rheostat will not work for them. Here you need electronic ballasts (EPG).
LED bulbs. For them, voltage regulation leads to a change in the spectrum. Therefore, the LEDs are regulated by changing the duration of the supplied pulses. In this case, flickering is not noticeable, since their repetition frequency reaches 300 kHz.

Connecting regulators to the load

The connection to the load is made in series (Fig. a). The regulator works the same way as a switch, but it is advisable to install the latter separately, since if it fails due to frequent switching, you will have to replace the expensive dimmer with a new one.

Dimmer connection diagrams

The main requirement is to maintain polarity. The phase is always connected to the dimmer input terminal, marked with the letter L, and from the output terminal the wire goes to the lamp. The phase can be detected using a voltage indicator.

A switch is often installed in the phase wire gap (Fig. b). It is located closer to the door, and the dimmer is located near the bed for easy control.

You can install another regulator and connect them together in parallel (Fig. c). To do this, 3 wires from each device should be routed into the junction box. Similar switching, similar to pass-through switches, is done in long corridors.

The use of dimmers differs in the number of loads. The single method consists of connecting one device or combined into a common group. The next control method is based on accent lighting to highlight individual zones.

Adjustable room lighting

Dimmer connection

The regulator is mounted in the installation box like a regular switch. First, it is connected when there is no voltage in the supply wires, and then installed in the box. Then the frame and brightness control knob are put on.

The basic scheme for regulating the light intensity of lamps for most conventional devices is the same. The difference is only in the additional parts to provide smoother handling and create stability at the lower limits.

To supply voltage to the lamp, the triac should be opened (Fig. a). To do this, a voltage must be created between the electrodes.

Circuits with triac regulation for incandescent lamps: a – the simplest; b – improved

At the beginning of the positive half-wave, capacitor C is charged through a variable resistor R. When a certain value is reached, the triac opens. At the same time, the lamp lights up. Then the triac closes and a similar situation occurs on the negative half-wave, since semiconductors pass current in both directions.

Thus, the light bulb receives “stubs” of half-waves with a frequency of 100 Hz, which was not the case when a rheostat was used. As brightness decreases, light flickering becomes more and more apparent. To avoid this, parts are added to the diagram, as shown in Fig. b. Triacs are installed according to the current load, and the permissible voltage is 400V.

By selecting the values of resistors and capacitors, you can change the initial and final ignition moments and the stability of the lamp glow.

For LED lamps

Despite the efficiency of LED lamps, garlands and strips, energy saving issues also apply to them. Often there is a need to reduce the brightness of the glow. LED lamps with conventional dimmers do not work and quickly break down during the regulation process. For this purpose, special regulators of two types are used: changing the supply voltage, controlling the pulse-width modulation method - PWM (load switching intervals).

Devices that control illumination by changing voltage are expensive and bulky (rheostat or potentiometer).

However, they are poorly suited to low-voltage lamps and turn on only at 9V and 18V.

A modern regulator is a complex device that provides smooth starting of lamps, brightness control and setting light switching modes using a timer.

An LED lamp differs from conventional strips and assemblies, which can only be connected using additional devices. Its main features are as follows:
Availability of standard sockets of types E, G, MR for connection.
Ability to work with the network without additional devices. If the lamp is powered by a voltage of 12V, the auxiliary devices are specified in its characteristics.

The generated luminous flux should not differ significantly from standard values.

If dimming is not provided, you should purchase special control devices with PWM regulation. They differ in installation types:

modular (in distribution panels) with control from remote controllers, remote controls or via special buses;
located in an installation box, like a switch, with rotary or push-button control;
remote units mounted in ceiling structures (for spotlights and LED strips).

PWM-based regulators operate on expensive microcontrollers that cannot be repaired. It’s easier to make a homemade device based on a simple microcircuit. The dimmer, based on the NE555 timer, operates stably at a voltage of 3-18 V with an output current of up to 0.2 A.

Dimmer circuit for LED lamps

The frequency of oscillations is ensured by a generator consisting of a resistor and a capacitor. The value of the variable resistor can be used to set the interval between turning on and off the load at output 3 of the microcircuit. The field-effect transistor here serves as a power amplifier, since the microcircuit cannot cope with the load from LED lamps. If the current through them exceeds 1A, the transistor requires a cooling radiator.

For fluorescent lamps

The brightness of the lamps can be adjusted using electronic ballasts, which perform the main function of starting them. A simple diagram is shown in Fig. below.

Controlling a fluorescent lamp using electronic ballasts

The voltage to the lamp is supplied from a frequency generator of 20-50 kHz. The circuit formed by the capacitance and the inductor resonates and lights the lamp. To change the current and thus the light intensity, you need to change the frequency. Dimming is carried out only after the lamp reaches full power.

The adjustable electronic ballast is created on the basis of the IRS2530D controller with 8 pins. The device is a 600V half-bridge driver with triggering, dimming and failure protection functions. The integrated circuit allows you to implement all the necessary control methods through 8 pins and is used in many ways to change the brightness of lamps.

Choice. Video

It is better to learn about the correct choice of dimmers in advance from the video.

When purchasing a dimmer, you should carefully study its technical characteristics and determine what types of lamps it is intended for. Choosing the right device makes it easy to connect it yourself without the help of specialists.

A dimmer is a special device that is designed to regulate the brightness of lighting. The dimmer reduces or increases the voltage, respectively, the brightness of the light increases or decreases. In addition, modern dimmers for LED lamps can be additionally equipped with automatic switching off the lamp, as well as smoothly adjust the power on and off. Some dimers are remote controlled.

The main function of dimmers for LED lamps is to adjust the brightness and power of lighting. In addition, using a dimmer, electricity savings are achieved by reducing the voltage power during operation of the lighting device. Modern dimmers can be set to turn on the lights when a person enters the room and turn them off when no one is in the room. Installing dimmers on LED lamps is economically justified.

Features of dimmers for LED lamps

If you want to dim the light every time you turn on the lamp, you should buy a lower wattage lamp. It is better to use the dimmer periodically, rather than every time you turn on the lamp.

When operating a dimmer with LED lamps, it is mandatory to have a choke in the lamp. Such dimmers are designed for lower power compared to conventional lamps.
The power of LED lamps is almost 10 times less than the power of conventional lamps, which is why their dimmers are less powerful.
Another characteristic difference from dimmers for conventional lamps is that to adjust them you do not need to increase or decrease the current. Here, the brightness of the LED lamps will be adjusted by changing the current pulses in the network. The pulse frequency can reach 300 kHz, and flickering occurs in the lamp. For human vision, such flickering will be completely invisible.

Design and principle of operation

All dimmers are similar in structure and are a switch with a rotating adjustment wheel or buttons. Each dimmer has two circuit connections. They are connected in the same way as switches, by connecting wires.

The principle of operation of dimmers for LED lamps is that the brightness of the lamp changes due to changes in the network current pulses. The width of the pulses changes, not the power. The dimmer operates on the principle of cutting off the voltage amplitude. Turning the light adjustment wheel clockwise makes the room brighter. Conversely, turning the wheel counterclockwise decreases the brightness.

What types of dimmers are there for LED lamps?

Dimmers can differ in the nature of control:

mechanical dimmer, push-button or with an adjustment wheel - the simplest dimmer design. Adjusts the brightness of the lighting using buttons or a wheel;
electronic dimmer— can be with a touch or contactless trigger sensor. They have a more complex structure. Lighting adjustment is carried out using a sensor or using infrared sensors;
acoustic dimmer– the sensor is triggered by a loud sound or voice commands. This type of dimmer has a slight drawback - it can change the brightness of the light at night if an object unexpectedly falls;
remote dimmer— the principle of its operation is based on the use of a remote control. Very convenient to use; you don’t need to get up and go to the dimmer to make the light brighter or darker.

Which dimmer should you choose?

It all depends on your taste. If you like the classic style of execution, take a simple dimmer with a wheel or adjustment keys. If you want independent control using voice commands, take an acoustic dimmer. For lovers of comfort, remote dimmers are perfect. Of course, remote dimmers are many times more expensive than mechanical ones, but the ease of their use justifies the expense. It is better to choose dimmers for LED lamps from trusted manufacturers. Cheap dimmers can quickly fail or may not work at all.

When purchasing dimmers for LEDs, calculate the total load that will fall on it. In this case, add 10-15% for the safety margin.

Is it possible to install dimmers for LED lamps yourself?

Installing a dimmer is very easy; it is connected no more complicated than a socket or switch. Installation should only be carried out with the dimmer in the non-operating position. Turn off the traffic jams and get to work. The wires are stripped, the phase is indicated by the indicator. The phase wire is connected to the terminal block marked “L”, and the second wire to the terminal block marked “N”. After this, the wires are clamped. Then the bolts are adjusted and the frame is put on. Now you can turn on the electricity.

If you have an electronic dimmer, then a parallel connection together with the switch is possible. That is, the light will be turned on by a switch, and adjustment will be made using a dimmer.

Dimmers regulate the brightness of lighting and save electricity. They are easy to use and install. Thanks to modern technologies, it is possible to control dimmers with a remote control and voice.

Did you know that it is possible to set a lighting scenario in an apartment, private house, office or public space? This can be arranged using special electrical installation devices - dimmers. These devices provide a sequential or alternating change in the power supplied to the light source, as a result of which the brightness of its glow is adjusted. In addition to controlling the flow of light, dimmers also perform other functions: they help save energy and increase the service life of 220 V LEDs.

What is a dimmer and why is it needed?

A dimmer (dimmer) is a multifunctional switch that controls the brightness of incandescent light bulbs, fluorescent lamps and LED lamps. Popular dimmers are equipped with microcontrollers that significantly expand the functionality of these devices.

A dimmer is a multifunctional switch that controls the brightness of lamps.

A single dimmer controls the operation of one lamp. The dimmers installed by the group control a variety of light sources. If there are several lamps in one zone, they can be connected to one dimmer, which changes the brightness of each of them.

Virtually all dimmers have the ability to switch, but not all are equally suitable for incandescent light bulbs and fluorescent lamps. Also, not all 220 V LED lamps can adjust the brightness of the light. If you connect such a lamp to a dimmer, it will work unstably or even lead to equipment failure. Therefore, before purchasing an LED, pay attention to its markings, the inscriptions on the box and in the manual, or ask the seller whether it will be connected to a dimmer.

Work principles

The dimmer operates like a rheostat. When the resistance of an electrical circuit changes, the current or voltage indicator changes. As the resistance increases, the voltage of the electric current drops. The light intensity of the lamps in the dimmer is regulated by a set of resistors included in the design of this device. Requests for the degree of illumination of a room at different times of the day may change. The dimmer helps create the optimal lighting level.

The dimmer works on the rheostat principle

If the design of the lamp does not have the possibility of dimming, then a dimmer operating on the PWM (pole width modulation) principle is suitable for it. True, such a device is quite expensive.

Advantages and disadvantages

The dimmer has undoubted advantages:

provides comfortable lighting at any time of the day;
fits perfectly into modern design;
plays an important role in zoning space with the help of light;
provides the effect of presence in the house due to periodic switching on and off of the light;
has the ability to connect and control within the Smart Home system;
easy to install;
allows you to save electricity.

The dimmer fits perfectly into modern design

Note! If incandescent lamps and LED lamps operate in a soft, dim mode, their service life increases by 10–15 times!

In addition to its advantages, a dimmer, like any electrical appliance, has disadvantages:

humming of lamps and failure of the device in the event of a decrease in the minimum load;
critical attitude towards the environment (possibility of overheating when the temperature rises);
impossibility of increasing the maximum load without using a power amplifier;
inability to connect inductive and capacitive loads;
Efficiency is too low when switching to night mode.

One of the disadvantages of a dimmer is the inability to increase the maximum load without using a power amplifier

Device Features and Functions

Dimmers differ in range, power (maximum load) and method of regulating lighting.

A dimmer for LED lamps regulates the lighting order, brightness, blinking and dimming mode, and in some cases even the color of the LEDs. Using a dimmer, light sources can be switched off automatically. The device operates remotely or according to a preset program that regulates the time the lights are turned on and off. The dimmer is installed instead of a regular switch.

Using a dimmer, light sources can be switched off automatically

Types of dimmers for LED lamps

Dimmers are classified by design, installation location, control principle, current load, installation method and other parameters.

Depending on the location of installation, dimmers are divided into wall-mounted, remote and modular.

Wall dimmers are mounted on the walls in rooms instead of switches.
Remote dimmers in the form of a small block are installed in close proximity to the lamps.
Modular dimmers are mounted in an electrical panel on a DIN rail. Automatic protection switches, RCDs and other devices are connected to it.

At the installation location

Wall dimmers are mounted on walls in rooms instead of switches
Remote dimmers in the form of a small block are installed in close proximity to the lamps Modular dimmers are mounted in the electrical panel on a DIN rail

There are also dimmers for external and hidden wiring.

According to control principle

Based on the control principle, dimmers are divided into mechanical, touch and remote.

Mechanical

A mechanically controlled dimmer is the very first and simplest device. On its body there is a wheel or buttons with which you can adjust the brightness of the LED lamps. As a rule, to start the device you need to press a handle, which is a large round button, and the light is controlled by turning this handle. To turn off the lighting, you do not need to return the handle to its original position.

A mechanically controlled dimmer is the very first and simplest device

Mechanical models also include keyboard and push-button models. Such dimmers, like regular switches, are equipped with a power disconnect key.

Touch

A dimmer with touch (contact) control looks more solid and modern. To control the light, just touch the touch display. But such a device is more expensive than a mechanical one.

Dimmer with touch control looks more solid and modern

Since there are no moving elements in the design of the touch dimmer, it is the most reliable compared to mechanical analogues.

Remote

A remote-controlled dimmer has a remote control that operates via radio or infrared channel. Using a radio channel, you can control the lighting from anywhere in the house, and even from the street. The infrared channel operates in the same way as on a TV, that is, to control the light, the remote control must be pointed directly at the dimmer.

A remote-controlled dimmer has a remote control that operates via radio or infrared channel

A type of remote control of a dimmer is control via a wireless Wi-Fi network. This method allows you to turn lights on and off, as well as control electrical appliances from a smartphone or tablet. Similar systems are used in Smart Home technology.

In addition, the dimmer can be activated by clap or voice. This control principle is called acoustic. It can also be classified as remote.

Which dimmer is better to choose

The choice of a dimmer is influenced by such factors as the technical parameters of the device, interior design, personal taste preferences of the apartment owner, as well as his financial capabilities. If you are not willing to overpay, purchase a mechanical dimmer with a wheel, button or touch control. If you prefer comfort and convenience, then your choice is a remote-controlled dimmer. If you never leave your smartphone, choose a dimmer with Wi-Fi control.

Connecting the device to the LEDs

We present to you a traditional diagram for connecting a dimmer to an LED lamp. If you connect several lamps, they must be connected in series. Please note that the dimmer is always placed in the gap of the phase wire rather than the neutral wire.

The cable coming from the junction box is connected to the terminal marked “L and arrow up”. The other wire is connected to the terminal marked “N and sloping arrow”.

The presented circuit allows you to easily replace a standard LED lamp switch with a dimmer.

Traditional circuit for connecting a dimmer to one LED lamp

Strip the wires and find the phase using the indicator.
Before installing the device, do not forget to turn off the electricity in the house.
Connect the wires to the terminals as described above.
Clamp the wires, adjust the bolts and put on the frame.
Connect power supply and check system operation.

If you connect several lamps, they must be connected in series

When connecting a standard dimmer to LED lamps, you should find out whether there is enough power for the operation of this device. Usually, instead of one incandescent light bulb, you can use two or three 220 V LED lamps. If there is insufficient load, the operation of LED lighting sources will be incorrect and they will quickly burn out.

If you add a semiconductor device triac (symmetrical triode thyristor) to a simple dimmer connection circuit, the functions of the device will expand significantly.

If you add a triac semiconductor device to a simple dimmer connection circuit, the functions of the device will expand significantly

Adding other elements allows you to control the light flux more smoothly, reduce the level of interference in the electrical network, etc.

Video: Example of a dimmer and its connection

Let's summarize: using a dimmer improves comfort in the home space, allows you to create different lighting options and helps save energy. These devices are relatively inexpensive and can be assembled with your own hands.
