PUSH Dimming (Switch Dim, Analogue) A dimming method using a simple retractive (non-latching) switch. The input from the switch to the driver is in addition to the main power supply to the driver. With Primary PUSH dimming, an additional live with a retractive switch and a neutral are connected to the driver.

What are the different types of dimming?

The four most popular methods for dimming LED lights are described below and cover 0-10Volt dimming, PWM(Pulse Width Modulation) dimming, Forward-Phase dimming(sometimes referred to a “Triac” or Incandescent Dimming) and Reverse-Phase dimming(sometimes referred to as an ELV or Electronic Low Voltage Dimming).

What are the two types of dimmers?

Most dimmers fall into these four bulb type categories:

  • Incandescent and halogen bulbs.
  • Dimmable compact fluorescent light bulbs.
  • Magnetic Low Frequency (MLV)
  • Electronic Low Frequency (ELV)


What does DALI dimmable mean?

This means that DALI can offer much more precise light level control and more consistent dimming. DALI is a standard, so, for example, the dimming curve is standardised meaning that equipment is interoperable between manufacturers.

What is the difference between DALI and DSI?

DSI is essentially the same technology as DALI in terms of messaging, however, DSI eliminates the individual addressing aspect of each light fitting found in DALI.

What is PWM dimming?

Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LED driver devices. PWM dimming takes a rectangle waveform with variable positive duty cycle (D) and adjusts the LED current proportionally.

What kind of dimmer do I need for LED lights?

LED bulbs have a low wattage, so you’ll need to have a dimmer that is 250W or 400W and ideally intelligent trailing edge, for smooth dimming. See our full range of LED suitable trailing edge dimmer switches.

Do you need special dimmers for LED lights?

A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.

How do I know what type of dimmer switch I have?

If you already have light bulbs and are looking for a dimmer switch, find the product page for the bulbs and check the PDF for a list of compatible dimmers to choose from. The specific dimmer compatibility information will always be with the bulbs rather than with the dimmer.

Do dimmers save electricity?

Not only do modern light dimmers save you energy, but they also extend the life of your light bulbs! Dimmers use a “Triac Switch” to rapidly turn a light circuit on and off to reduce the energy flowing to a light bulb. This switch will cut the energy running to the fixture up to 120 times in one second.

What does DSI mean in lighting?

The Digital Serial Interface (DSI) system was launched into the lighting market back in 1992 by Tridonic and is a more controllable version of digital dimming, which enables the user to group luminaires, operate daylight linked dimming as well as other control options.

How do you wire a DALI light?

Quote from the video:
Quote from video: The red wire into the positive input terminal the black wire into the negative input terminal and connect the green earth ground wire to the faceplate of the switch.

What is a 1 10V dimmer?

Explaining 1-10V dimming



1-10V dimming uses a controlled DC voltage signal to vary the brightness of the fitting(s). 1 is the lowest level, typically 10% of light output, and 10 is the brightest, at 100% of the light output. There is a linear pattern on light output in between 1 and 10V, so 5 would be circa 50%.

What is the difference between phase dimming and 0-10V?

The main difference between 0-10V and 1-10V is the direction of the current between dimmer and driver. 0-10V is a current source system, which means that the dimmer provides the power for the 0-10V signals – a mains connection to the dimmer is necessary.

Can I use a 1-10V dimmer on a 0-10V driver?

This is incorrect! The main difference between 1-10V and 0-10V dimmers is the current direction, not the dimming level. Both of 1-10V dimmer and 0-10V dimmer are capable of dimming the load down to 0%.

Is 0-10V dimming AC or DC?

direct current voltage

0-10V dimming is a lighting control method that – on direct current voltage (DC) between 0 and 10 volts – can produce light at varying intensity levels.

What is the difference between ELV and 0-10V dimming?

ELV dimmers are generally very compatible with LED loads, offering smoother dimming to low levels. 0-10V: 0-10V dimming is commonly used for commercial fluorescent and LED installations and is one of the simplest and earliest commercial dimming methods.

What does 10V mean?

0-10V dimming applies a direct current voltage (DC) between 0 and 10 Volts to produce light at varying intensity levels. At 10V, the lights controlled by the dimmer are at 100% brightness. At 1V, the lights are at 10% measured brightness, which may actually be perceived as 32% brightness.

Can you dim LED panel lights?

When it comes to LED lighting people often wonder if LED lighting is dimmable. The short answer to this question is: Yes, LED lighting is certainly dimmable!

What is the difference between dimmable and non-dimmable LED?

Dimmable LEDs, on the other hand, have special circuitry inside. This makes them able to respond to changing phase forms that produce the dimming effect. Non-dimmable LEDs are designed to either be fully powered ON or OFF. Its circuitry cannot handle special phase forms.

What happens if you put a non-dimmable LED bulb in a dimmer?

If you use non-dimmable lights in a dimmer circuit, they will either flicker or just run at full brightness. They will likely burn out faster, too.

How do I know if my LED lights are dimmable?

#1 – If you bought a finished LED fixture or bulb, check to make sure the packaging specifically states that it is dimmable. This should be stated in the description or the technical specifications of the light.

Can I install a dimmer switch on any light?

A dimmer switch can be installed anywhere that an existing on or off switch is in place. Replacing the current toggle switch with a dimmer switch will allow you to change the lights’ brightness, so long as you are using a light bulb that is compatible with the dimmer you have chosen.

Why do my LED lights flicker when dimmed?

There are many reasons why an LED lamp can flicker, but the most common cause is a lack of resistance in the lamp to allow the dimmer curve to work correctly. This is not a new issue; it’s been around for a long time, but is becoming more “noticeable” with the major increase in LED usage.

Can all bulbs be dimmed?

The answer is yes, all incandescents are dimmable. They have the largest controllable dimming range from 100% full light, all the way down to 0%. Incandescents produce light by allowing an electric current to flow through a metal filament surrounded by inactive nitrogen and argon gas.

How many LED lights can you put on a dimmer?

This means that if an incandescent dimmer is rated at 600W, you can’t assume you can use twenty-four 25W LED fixtures. A good rule of thumb is to allow 100W for each LED fixture so in this case, the 600W dimmer can handle only six LED fixtures.

What is the difference between LED dimmer and incandescent dimmer?

The main difference is that you have a smaller dimming range (typically 70-90% range vs. 100% with incandescent or halogen). LED Bulbs may not shut off at the lowest dim setting like traditional bulbs. This happens because the dimmer thinks the bulb is completely off due to the low amount of wattage the LED consumes.
