What Is A Trailing Edge Dimmer

When it comes to creating the perfect ambiance in your home or office, lighting is key. And with the rise of LED lighting, it’s important to have the right dimmer to control the brightness and mood of your space. Trailing edge dimmers are a popular choice for LED lights, but with so many options on the market, it can be overwhelming to choose the right one for your space. In this article, we’ll discuss the key factors to consider when selecting a trailing edge dimmer.

Introduction

What trailing edge dimmers are

A trailing edge dimmer, also known as reverse phase dimmer, is an electronic device used to regulate the intensity of light produced by lamps. It works by cutting off the current at the end of each cycle of alternating current, which is known as the “trailing edge”.

This type of dimmer is used to control the lighting levels in a room, and is particularly useful for LED lights, which are increasingly becoming the preferred choice of lighting for many households. Trailing edge dimmers are considered to be more efficient than the traditional leading edge dimmers, as they are able to reduce the amount of power used to power the lights.

 History and evolution of dimming technology

Dimming technology has been around for centuries, but only in recent years has the technology become more accessible and widely used. The earliest dimmers used a rotary knob that manually adjusted the voltage level passing through the lamp. This type of dimmer was inefficient and wasteful, as much energy was lost in the form of heat.

In the late 1980s, leading edge dimmers were introduced, which used a triac to control the voltage passing through the lamp. This allowed for more precise control of the dimming process, but was prone to flickering and humming. Trailing edge dimmers were then developed, which used a higher frequency to reduce flickering and humming, and allowed for a more efficient and precise dimming process.

As the technology continues to improve, dimming systems are becoming increasingly popular, as they are more energy efficient and provide more precise control over the lighting levels in a room.

Technicals about Trailing edge dimmer

How trailing edge dimmers work

A trailing edge dimmer is an electrical device that is used to adjust the brightness of lights in a room or space. It works by reducing the voltage supplied to the light source, resulting in a dimmer and softer light.

The dimmer works by creating a “trailing edge” effect, which is when the voltage at the end of the waveform is reduced, rather than the beginning. This allows for more precise and gradual dimming than a leading edge dimmer, which reduces the voltage at the start of the waveform. Trailing edge dimmers are generally used with LED lighting, and they are typically more efficient and produce less heat than leading edge dimmers.

Additionally, trailing edge dimmers are better at dimming LED lights than leading edge dimmers, as they are able to create a smoother dimming effect.

Key components and their functions

The key components of a trailing edge dimmer are the dimmer switch, the linear dimmer control, and the triac.

The dimmer switch is used to select the desired level of brightness, and the linear dimmer control is used to adjust the voltage supplied to the light source. The triac is an electronic switch that controls the current and voltage supplied to the light source, and it is used to create the trailing edge effect. The triac is typically located inside the dimmer switch, and it is triggered by the linear dimmer control.

The dimmer switch is the main user interface, and it is used to select the desired level of brightness. The linear dimmer control is a knob or slider used to adjust the voltage supplied to the light source, and it is typically located near the dimmer switch. The triac is an electronic switch that is triggered when the linear dimmer control is adjusted, and it is used to reduce the voltage supplied to the light source, resulting in the trailing edge effect.

Differences between leading edge and trailing edge dimming.

When it comes to dimmers, there are two main types: leading edge dimmers and trailing edge dimmers. Leading edge dimmers are the more traditional type of dimmer, and are often used for incandescent and halogen lights. Trailing edge dimmers, on the other hand, are a relatively new technology that has become increasingly popular with LED lights. Trailing edge dimmers offer a smoother, more efficient dimming control, and are typically the preferred type of dimmer for LED lights.

Leading edge dimming

Leading edge dimmers cut the initial spike of the AC voltage waveform when the dimmer switch is turned down. This makes the light less bright. However, leading edge dimmers can cause a buzzing sound when used with LED lights because they are not designed for LED technology.

Leading Edge Dimming, also called TRIAC dimming, turns off the current at the beginning of the AC waveform, right after it crosses zero. It is often used with incandescent bulbs and causes a voltage surge every half cycle, increasing the current to the light source.

Trailing edge dimming

Trailing edge dimmers, on the other hand, work by cutting off the trailing edge (the end of the AC voltage waveform) of the AC voltage waveform when the dimmer switch is turned down. This type of dimmer is specifically designed to work with LED lights, resulting in a smoother dimming experience with no buzzing or humming sound. Trailing edge dimmers are also more energy efficient than leading edge dimmers, making them a better choice for those who want to save energy while still controlling the brightness of their LED lights.

Trailing Edge Dimming, or electronic dimming, operates by cutting off the current as the AC waveform concludes, right before crossing zero. This dimming method is often paired with electronic drivers and is designed to avoid sudden voltage spikes, thereby preventing a surge in current to the light source.

Types of Trailing Edge Dimmers

Various models and brands in the market

Trailing edge dimmers are available in various models and brands in the market. These dimmers come in two main types: traditional incandescent dimmers and LED trailing edge dimmers.
