Dimmers are devices that allow us to control and adjust the intensity of light in our surroundings. Whether it is in our homes, offices, or other spaces, dimmers provide us with the ability to create the desired ambiance and mood by altering the brightness levels of our artificial lighting. This introduction will explore the classification of dimmers as well as their applications in various aspects of our lives. From enhancing the atmosphere in our homes to improving energy efficiency and reducing electricity consumption, dimmers play a crucial role in modern lighting technologies. Understanding the different types of dimmers available and their applications can help us make informed decisions when it comes to choosing the right lighting solutions for different settings.
Dimmer is a product that is widely used in lighting systems, but they are still unknown to many people. Let’s find out what is dimmer? Classification and application of dimmer in life offline!
What is dimmers?
Dimmer is a device that is connected to a fixed light to reduce the brightness of the light. By varying the waveform of the voltage applied to the lamp, it is possible to change the intensity of the emitted light.
While a dimmer is a transformer and transformers can be used for a wide variety of applications, the term dimmer is only used for devices that dim the lighting of incandescent, halogen, compact fluorescent and LED lamps.
Dimmers come in many different sizes from small indoor light switches to large capacity used for stage or building lighting projects.
Working principle of dimmers
Dimmer works based on the change of voltage flowing through the power consuming device, helping to control the lighting ability of the lamp better.
In other words, the dimmer works based on the adjustment of the resistor. Because resistance dissipates power due to heat generation, resulting in a change in amperage. Thereby changing the light intensity of the lamp.
Types of popular dimmers today
There are many types of dimmer but the most common are leading edge dimmer and trailing edge dimmer. Both work by cutting the voltage at different phases of the sine wave of the alternating current, thereby reducing the energy delivered to the bulb.
Leading edge dimmer
Leading edge dimmers are the most common. This type has existed for a long time and is used to control the brightness of incandescent and halogen lamps. This type has a high power range in the range of 250W to 1000W, so it will not work for low-power LEDs.
Trailing edge dimming
Trailing edge dimming, also known as LED compatible dimmer, is used for LED bulbs because of many similar characteristics, such as equivalent wattage ranges. The power required for this type of dimmer is quite low, making it suitable for low-power LED bulbs.
Universal Dimmer
Universal dimmer is used to control halogen, incandescent, compact fluorescent and LED lamps.
This type can give you maximum brightness control range and is free from light flickering. However, when using with compact fluorescent lamps and LED lamps, it is necessary to check whether the lamp is dimmable or not.
Dimmer for incandescent and halogen lamps
This type is specifically designed for dimming incandescent and halogen lamps. So you must not use for compact fluorescent lamps and LEDs because of poor performance.
Fluorescent lamp dimmer
This type is used to control the brightness of fluorescent lamps
Dimmer ELV
ELV dimmer is used for low voltage transformer control and LED power supplies such as led string lights, tracklights. To install an ELV dimmer requires a neutral wire.
Low Voltage Magnetic Dimmer MLV
This type is used for low voltage and magnetic wall lamps. MLV is usually heavier and larger than ELV.
High Power Dimmer
This type is used to control the brightness of high power lamps, mainly 1000W. If you have a lamp with a capacity of 600W or more, you should choose this type.
Practical application of dimmer in life
Adjust the brightness of the lamp
Some types of lighting such as desk lamps, night lights, lights in theaters, stage lights will use dimmer.
Dimmer supports adjusting the light level that best suits the needs of the user. When turned off, the light will dim and then turn off completely. When turned on, the light will gradually become brighter and then completely bright, creating a comfortable feeling for the viewer because the eyes do not change the light suddenly.
Adjust fan speed
Common fans used in households or offices always need a dimmer. Because many times the manufacturer’s default wind level may not match the user’s needs.
Example : You are turning on the fan at number 3 and feel a little cold. But when reduced to level 2, it is not cool enough. At this point, the dimmer will help you solve the problem easily thanks to the ability to adjust flexibly. In addition, rotating the dimmers is also gentler and more friendly.
Application in agriculture
Dimmer is used to change the brightness of lights in agriculture. In farming, people often use incandescent lamps to change the ambient temperature. Dimmer is a great product to change the ambient temperature indirectly through lights, very convenient.
Other Apps
In addition, dimmer is also used in many other things. For example, dimmer to change the voltage of the current,…
Notes when choosing and installing dimmers
Safety Note:
Regarding electrical equipment, safety is always the first consideration, specifically the prevention of fire and explosion. You should choose famous brands and high-quality products to use.
Notes on installation :
- Check whether the electrical equipment supports use with the dimmer.
- When installing, the electrical connections and connections must be carefully checked and tightened to prevent the electric motor from causing a fire.

In conclusion, dimmers are devices that allow us to control and adjust the intensity of light. With the ability to increase or decrease the brightness of lighting fixtures, dimmers provide significant benefits in various applications across different aspects of life.
Dimmers can be classified into different types, including rotary, slider, touch-sensitive, and remote-controlled dimmers. Each type offers unique features and ways of adjusting the light output, catering to diverse preferences and requirements. Furthermore, advancements in technology have also given rise to smart dimmers, which can be controlled through smartphone applications or integrated with home automation systems, adding convenience and flexibility to their usage.
The application of dimmers in various aspects of life is widespread. In residential settings, dimmers provide ambiance and mood lighting, allowing homeowners to create cozy and relaxing environments. They also contribute to energy conservation by reducing the overall energy consumption of lighting fixtures. In commercial establishments, dimming systems are beneficial for creating attractive atmospheres in restaurants, hotels, and entertainment venues. Moreover, dimmers find utility in medical facilities, photography studios, and theaters, where precise control of light intensity is essential for specific tasks.
Overall, dimmers play a vital role in enhancing our lighting experiences. Their diverse classification and wide-ranging applications demonstrate their versatility and importance in our daily lives. By providing control over light output, dimmers offer not only functional benefits but also aesthetic and energy-saving advantages, making them indispensable devices in modern lighting systems.
