TRIAC dimmers are especially popular where LEDs are usedĪ TRIAC control will have a sophisticated IC that controls the TRIAC, thus maintaining the brightness level. Using phase control, the TRIAC controller provides reliability It does this by connecting to either of two wires in your main power cable.Ī TRIAC controller provides efficiency and permanence What does a TRIAC do in a dimmer switch?Ī TRIAC is a semiconductor that switches current in one direction and then stops, allowing it to be switched back the other way. The dimmer for incandescent bulbs uses a different way to adjust the voltage. This makes it switch off more quickly because there’s no time for the power to reverse back. When you turn on the light with a leading-edge dimmer, it sends an electric pulse down to the light just before switching the current on. Triac dimming LEDs have been available for several years, and some perfect dimmable LED light bulbs use Triac dimming. Triac dimming is the cheapest, and the majority of LED bulbs on the market are Triac dimmable. Because of this, we always advise that an electrician replace the LED bulb. Triac dimming LED light bulbs to require a solid-state dimmer, which should be used in conjunction. ![]() They can be used with leading and lagging edge dimmers and offer smooth, flicker-free dimming. TRIAC dimming is the safest and most energy-efficient method of LED light dimming. It does this by connecting an electronic component called a TRIAC to either of two wires in your main power cable. The dimmer looks for a particular voltage on the mains line and starts to turn the LEDs off. Trailing-edge dimmers switch off slowly after the current has changed direction, allowing them to be more beneficial for normal AC loads, which are resistive. The power coming from your mains supply flows in one direction and then stops. MAGNETIC LOW VOLTAGE DIMMER FOR LED LIGHTS DRIVERSTRIAC dimmer stands for ‘Triode for Alternating Current.’ They’re one of the most widely used semiconductors in AC line dimmable applications in LED drivers and light bulbs. Triac dimmer allows users to dim conventional low voltage lightings, such as LED and CFL lamps, halogen, or induction. This means they’re the safest type of LED dimmer on the market. Leading-edge dimmers switch on quickly before the current can change, allowing them to turn off more quickly. ![]() The power coming from your mains supply flows in one direction and then stops and reverses. An ELV dimmer works like this: the electrical load is turned off at the end, or trailing edge, of the Alternating Current (AC) waveform.13 Phase dimmer What is a leading-edge TRIAC dimmer? ELV dimmers are also called simply “ electronic dimmers”, as well as “trailing edge dimmers”. An ELV dimmer is known by a number of names. They are also more budget friendly but are noisy and only last 5-6 years.ĮLV stands for Electronic Low Voltage. The electronic transformers are lighter and smaller than their magnetic counterparts. MAGNETIC LOW VOLTAGE DIMMER FOR LED LIGHTS PROFESSIONALModern professional dimmers are generally controlled by a digital control system like DMX or DALI.īesides, what is the difference between magnetic and electronic transformers?Įlectronic Transformers The higher the frequency of the voltage, the smaller the transformer needs to be to provide the required output voltage. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Magnetic Low Voltage dimmers are specifically designed to prevent DC voltage from being applied to the transformer.įurthermore, what is an electronic dimmer? Dimmers are devices connected to a light fixture and used to lower the brightness of light. Regular incandescent dimmers often contain a small amount of DC voltage, which is harmless to a regular incandescent load but may damage magnetic transformers. Just so, what is a magnetic low voltage dimmer? Dimmers for magnetic low- voltage transformers use a technology known as standard phase control or “leading edge,” whereas 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 ( ![]()
