Do I need a trailing edge dimmer?

Do I need a trailing edge dimmer?

Trailing edge dimmers have a much lower minimum load than the leading edge, making them far more suitable for powering LEDs. The 10% rule is very important when using trailing edge dimmers with LEDs. The main benefit of trailing edge dimmers is that they are able to control lower wattage loads.

Are Lutron dimmers leading edge?

Dimmers for use with magnetic low-voltage transformers use a technology known as standard phase control or “leading edge,” where as dimmers for electronic low- voltage transformers use reverse phase control or “trailing edge.” Standard phase control is for use with either inductive (MLV transformers, fans) or resistive …

What happens if you dim a non dimmable LED?

If you use non-dimmable LEDs on a dimmer, what happens? The bulb will not dim properly. The circuitry inside non-dimmable LEDs won’t be able to handle low or pulsing current levels and will eventually become damaged, because they are only designed to be either fully powered ON or off.

Why do LED lights need a special dimmer?

With LED bulbs you cannot limit the power to the driver, because if you do, the bulb would flicker or just turn off. A dimmer for LED lights is specially designed to send power and control signals to each type of electronic LED driver.

What is the difference between a leading edge and a trailing edge dimmer switch?

These two types of phase cutting dimmer get their names from the part of the AC wave that they cut off. Leading edge dimming cuts of the front edge of each waves’ half cycle. Conversely trailing edge dimming cuts out the second half of each waves’ half cycle.

Do dimmers work on LED lights?

LED light bulbs can be used in light fixtures controlled by dimmer switches, but you may well find that traditional dimmers may not work—or may work inadequately—with some LED bulbs . The bottom line is compatibility.

What is an ELV dimmer?

How ELV Dimmers Work. ELV stands for Electronic Low Voltage. An ELV dimmer is known by a number of names. ELV dimmers are also called simply “electronic dimmers”, as well as “trailing edge dimmers”. These names come from the way in which this dimmer transitions your LED’s luminosity.

What is trailing edge dimming?

Trailing edge dimmers (aka “electronic dimmers”): The electrical current (sinusoidal signal) is turned off at the end of the AC input waveform immediately before the zero crossing. Traditionally used for electronic drivers or low voltage transformers (capacitive loads)

What is a leading edge?

The leading edge is the part of the wing that first contacts the air; alternatively it is the foremost edge of an airfoil section.
