If you're looking to learn more about Dimming LED Strip Lights and dimmable drivers, then this article is for you. It's easy to be overwhelmed by the sheer volume of information on the internet. To complicate matters, a lot of it is wrong, out-of-date, or just plain mixed up. And what's worse is that almost all of it assumes that you already have some knowledge and experience in electronics.
In this article we'll cover the many different ways you can dim your LED light strips, including TRIAC and pulse-width modulation (PWM) dimmers. BASICS Why do we need a method to dim our LEDs? Even if your LEDs were designed for outdoor or commercial use, it doesn't mean that you can use them like that all the time. If you're planning a party, for example, it'd be nice to increase or reduce the brightness of your lighting as needed. The same goes for an office environment: some people work better in bright conditions and thrive during daytime-like levels of illumination, while others can't concentrate unless there's enough subdued light.
Benefits of Dimming LED Strip Lights
Dimmable lighting gives you the option to match the lighting to your particular activity. You may want a bright light as task lighting, but a dim, relaxing light during evening dines.
Dimming also sees extensive use within commercial and industrial spaces. For example, dimmable lighting offers flexibility to your office space. It allows for optimal lighting that suits your employees’ needs.
This is especially important if you have multiple workstations within one room. By being able to adjust the brightness of each desk lamp, you can ensure that each employee has enough light while they work without making others feel uncomfortable or under-lit.
1. Are all LED Strips Dimmable?
The answer is yes, all the strip lightings are dimmable, the brightness can be adjusted by providing a compatible DC signal. The LED Strip Light has two ways to dim it: one is to use a dimmer controller and another one is to use PWM control method. The first way is using a dimmer controller that directly adjusts the voltage of power supply. The second way is to use PWM control method (Pulse Width Modulation) which directly controls the duty cycle of each pulse.
2. Factors You Need to Consider When selecting a Dimming Method
When selecting a dimming method, you should consider the following factors:
Your Project’s Size: The size of your project is an important factor that will determine the type of dimming system you choose. The larger your project, the more likely it is that you will need a dedicated circuit to control its lighting elements. In addition, if you are planning to install several different types of lights on one circuit (such as incandescent and fluorescent bulbs), then you might want to consider using a different type of dimmer.
The Type of Dimmer Interface You Prefer: Some people prefer using a toggle switch while others prefer using a rotary knob. If you are looking for convenience and ease of use, then it is best to choose a rotary knob light dimmer as this allows users to adjust the light intensity by simply rotating their wrist. On the other hand, toggle switches are easier to install than rotary knobs because they require fewer wires and connections.
Your Budget: Dimmers come in various price ranges; therefore, it is important to ensure that you get one that meets your needs at an affordable cost.
3, Different Dimming Methods
Since LED strip lights are now becoming increasingly popular, many people are curious about them and want to know more about the different dimming methods for LED strip lights. Today, we will introduce some dimming methods for LED strip lights.
3.1 Triac Dimming
Most wall dimmers available today use the TRIAC dimming signal. You’ll need to find a dimmable power supply for these wall dimmers.
- The TRIAC dimmable power supply has two functions:
- Change 120V/220V AC to 12/24V DC signal for led strip lights.
Interpret dimming signals produced by the Triac wall dimmer and then translate that into the LED strip’s output.
You’ll need to connect the TRIAC dimmer to the dimmable power supply, then link the power supply’s output to the LED strip.
To avoid voltage drops, ensure that your power unit stays close to your strip lights. Here are the two types of Triac dimming options.
3.2 Low-Voltage PWM Dimming
PWM, or “pulse width modulation” is a dimming method used for many LED strip applications. PMW is a digital signal that “talks” to your strip’s power supply to adjust brightness. You can install a DC PWM dimmer between a standard, non-dimmable power supply, and the LED strip. It usually has a turn dial (potentiometer) that adjusts the LED strip brightness. The power supply can be any standard DC power unit and does not need to be dimmable.
Compared to TRIAC dimmable power supplies, these cost cheaper and are readily available. This simple circuit design works well for portable installations where you don’t have to build a dimmer into a wall. DC PWM dimmers are very simple to assemble, easily connecting to the power supply and LED strip.

3.3 RF Dimming
RF or “radio frequency” dimming provides a remote way to adjust your strip brightness.
Unlike the wired inline LED dimmers, you can dim the led strip by remote control, the distance can get as far as 20 meters in diameter.
3.4 WIFI Dimming
A smart dimmer allows you to control your LEDs remotely via a WiFi connection. When setting up a “smart” home or office lighting system, these dimmers are necessary.
You can operate the dimming by using a mobile app. This feature lets you adjust brightness using Alexa or Google Assistant voice controls.
3.5 0/1-10V Dimming
0-10V dimming lets you adjust brightness by altering DC voltage powering your strips.
It can vary voltage between zero and ten volts – zero being “off” and ten at 100% brightness output.
3.5 DALI Dimming
DALI dimming is a step further from the 0-10V system. Like the 0-10V, this dimmer allows you to adjust many LED strips over a wide area using a central controller.
This method also allows individual users to adjust brightness for specific zones using smaller LED dimmers.
3.6 DMX Dimming
“DMX 512” also works by regulating voltage in the transformer to reduce brightness.
Despite being an old dimming method, DMX is still used today. Applications include large-scale installations, such as concerts, theatres, and other performance venue lighting. This method allows for independent control of different areas of the lighting project. It can run up to 512 DMX receivers, also called channels.
There are two ways to wire this dimming system: daisy-chaining and splitting.
The Daisy Chain method requires connecting the wires of each fixture from a loop of the previous one. By wiring this way, you’ll get a line of fixtures that connects to the receiver, decoder, and console of the DMX system. It has a limitation, though. You won’t connect more than 32 fixtures in one chain. Going over this limit will hinder the signal strength required for DMX communication.
DMX splitting is needed if you need to connect more than 32 fixtures. Splitting allows you to expand the communication network by duplicating the DMX output many times.
What’s the Difference Between an LED Controller and Dimmer?
Regarding LED lighting systems, you may be confused about the terms “controller” and “dimmer.” Simply put, both terms mean the same thing. Both devices allow you to manipulate the settings and brightness of your installation.
Controllers are often used to manage multiple lights at once, while dimmers can simply turn lights on and off.
A controller is a device that allows users to change the color temperature of a light installation with a touch of a button or remote control. Controllers have become increasingly popular in recent years as more people are looking for ways to customize their homes with unique colors and effects. LEDs can be controlled using software that allows users to save and recall presets for different moods or occasions.
Dimmers are devices that allow users to adjust the intensity level of light sources like incandescent bulbs or fluorescents by turning them up or down manually. They work by altering an electrical signal from its source so that more current flows through it when turned up — making it brighter — while decreasing current flow when turned down — making it dimmer.
Why Do LEDs Flicker When Dimmed?
The leading cause of this flickering is voltage fluctuations from surge wattage. However, there are instances when LEDs may flicker when you try to dim them. The most common reason for this is the use of a dimmer that does not work well with LED lighting.
A good example of an unreliable dimmer is the standard light switch that you would find in your home. This type of dimmer works by turning off and on the power to your light bulb at a certain frequency. The problem with this method is that it does not take into account how quickly an LED reacts to changes in current or voltage.
The best way to avoid flickering issues with LEDs is to use a good-quality dimmer switch from the start. There are many options available that can help you get started including:
1) A phase control dimmer that works by changing the phase angle between supply and load current to reduce power without changing its frequency.
2) A PWM dimmer that uses pulse width modulation (PWM) to vary the duty cycle of the signal so that only part of its cycle is active at any time, resulting in reduced power consumption without changing frequency or voltage.
Why Do LEDs Flicker When Take Photo or Video?
You may have noticed that your LED lights flicker when on camera or video. This is because the shutter speed of your camera is too fast for the light to be steady.
The flicker you see on the camera is caused by the frequency of the flash being too low for the frequency of the shutter speed.
This is called a stroboscopic effect, which occurs when a light source is moving too quickly in relation to a recording device (for example, a video camera).
When taking photos or videos with your camera, you can set it to a lower shutter speed to avoid this effect.
Will Dimming Reduce the Tape’s Service Life?
If you have an LED light that is dimmable, you may be wondering whether or not it will damage the bulb. Will dimming reduce the tape’s service life? This is a question that many people ask when they are considering purchasing a dimmable bulb.
Dimming doesn’t generally affect the lifespan of LEDs. Reducing an LED light’s brightness will produce less heat. Reduced heat is always suitable for your LED’s internal components. However, there are some cases where this may not be true. For example, if you have a halogen bulb that has been converted into an LED bulb, then it is possible that dimming could reduce its lifespan because halogens produce more heat than LEDs do.
When buying an LED light fixture, always check the specs to see if it can be dimmed and what range of brightness you will get from each level of dimming. If you want to save energy by using fewer watts per hour (W/H) then you might want to choose one with a lower maximum brightness setting like 25% or 50%.
Do Dimmers Save Electricity?
As you might have guessed, the answer is a little more complicated than that.
The energy-saving qualities depend on which type of dimmer you use. Older dimmers consume the same power amount despite producing decreased brightness. In this case, that extra unused energy converts to heat instead.
Modern dimmers are better at saving energy, but they still aren't perfect. They're designed to mimic incandescent bulbs by going through a few halogen cycles before reaching full brightness. This means it takes time for them to reach their full potential. However, many modern bulbs don't need to be dimmed as much as older ones did because they produce more light per watt than older bulbs do.
Dimmers also require extra hardware and wiring in order to function properly — so if you're trying to save money on installation costs, you might want to consider other options like motion sensors or timers instead of dimmers.
Conclusion:
Reading through this article should have given you an excellent idea of what dimming LED strip lights and drivers are all about. LED light has finally entered the mainstream for home illumination, but there are still a lot of people who don't know much about them. It's important to learn as much as you can so that you can make informed decisions when there's no one else around to rely on.
