A Guide to Dimmable LED panel lights

Things to think about while dimming LED panels

It is more difficult to dim LEDs than it is to dim incandescent lamps. Dimming LEDs, however, can work for you and become a terrific way to save even more energy and manage your lighting environment if you follow our advice.

Make that the LED panel, or more precisely the driver, is dimmable before adding dimming to your lighting arrangement. The majority of LED panels are sold with non-dimmable drivers; dimmable drivers require more electronics, which raises the cost of the driver.

If everything is resolved, selecting your preferred dimming method merely requires browsing our selection of dimmer switches.

Dimming techniques

Since this is the way that is typically used in homes, many people will be familiar with mains dimming. In place of a light switch on a wall, mains dimmers are typically rotating devices. They have a knob that you may turn anticlockwise or clockwise to raise or reduce the amount of light they produce, and push in to turn on and off.

By slicing up the electrical signal coming from the mains, mains dimming operates. By repeatedly turning on and off the electric current every second, it achieves this. Because the power goes out for a portion of each second due to the frequent switching, less power is available to the light.

Full power is used to turn the light on and off, but less light is produced overall than if it were left on all the time. Our brain interprets this as a continuous, muted light source since our eyes cannot handle the fast change.

In the UK, electricity is delivered as a wave with a frequency of 50Hz. That implies that this wave occurs 50 times every second. There are 100 cycles of current every second—50 positive cycles and 50 negative cycles—due to the mains' alternating current, which changes from positive to negative with each cycle.

To achieve mains dimming, the power is turned off twice throughout each wave, once for each cycle of current.

Leading Edge and Trailing Edge are the two subtypes of mains dimming. But, there is no need to be concerned because both Leading Edge and Trailing Edge drivers are compatible with the Varilight V-PRO dimmers that we recommend for all of our LED Panel TRIAC dimmable drivers.

Power dimmer selection

When LED drivers are first turned on, they draw a lot of current for a brief period of time while their internal capacitors charge. "In-rush" refers to this situation. The overall power consumption is unaffected by this, so LEDs continue to be excellent energy-savers. However, a dimmer will now "perceive" them as having a higher wattage.

Dimmers for LED lighting are consequently de-rated for use with LED products. As a result, even though the dimmer may display a 400W rating, the LED dimming rating may only be 100W. The manufacturer's rating for LED dimming should therefore always be checked and followed.

Benefits and drawbacks of mains dimming Benefits

They are simple to install because no additional wiring is needed.

Disadvantages:

It is always best to check with the supplier of the dimmable LED Driver for suitable compatible dimmers because not all mains dimmers are compatible with all LED drivers.

Capacity – The LED dimmer's ability to dim is limited by the number of LED light panels that can be dimmed collectively. For instance, the Varilight V-PRO 300W dimmer's 300W LED maximum load. As a result, this dip can dip up to seven 40W LED panels at once.

Performance: While we typically find that the combination of our dimmable LED panel drivers and Varilight V-Pro dimmers offers very smooth dimming performance, this is not always the case with products from other suppliers.

Cost: Compared to certain alternatives, mains dimmable drivers and corresponding dimmers are more expensive (1-10V dimming).

Dimming at low voltage

This method, unlike mains dimming, delivers an electronic message to the driver, who then uses the lamp's electronic components to dip the lamp as a result. The dimmer in low-voltage dimming only directs the drivers' actions. This is distinct from mains dimming, in which the power is reduced by the dimmer and passed through the driver.

Low-voltage dimming uses protocols, which are essentially established methods of information transmission, because the dimmers don't actually do the work but rather instruct the drivers.

The most used protocols are DALI and 1-10V/0-10V. However since individuals who want to install DALI are almost definitely already familiar with that technology, we will solely talk about 1-10V / 0-10V for the purposes of this post.

The 0/1-10V dimming wires are an additional pair of wires that 0/1-10V dimming drivers feature in addition to the AC in and DC out wires. These wires on our drivers are color-coded red (+) and black (-). A 0/1-10V dimmer is linked to these 0/1-10V dimming wires. 10V would be seen if you placed a voltmeter across these wires. The driver converts the variation in voltage back to the dimmer, which is essentially a variable resistor, into a change in current output to the LED panel. The light output increases as the current is reduced, and decreases when the current is increased.
