#MAGNETIC LOW VOLTAGE DIMMER FOR LED LIGHTS DRIVER#

TRIAC dimming LED driver is the best option for powering AC LEDs from mains power.

TRIAC dimming LED driver is a LED drive that supports the dimming of AC mains (120V or 240V) voltage using a TRIAC switch. The most significant difference between the Smart Dimmer and the standard dimmer is that it supports TRIAC dimming mode, which means that instead of directly controlling the LED current, there’s a separate control circuit for driving the TRIAC(or thyristor). LED lighting applications users are familiar with. Without this module, you may find that the human eye can see the flickering of your TRIAC dimmer LED driver at 50% or more minor brightness levels. The smart dimmer uses PWM to reduce noticeable flicker. It is mostly used for improving the dimming effect of the TRIAC dimmer LED power supply. The smart dimmer module is one dimmer module. This will generate a magnetic field that will bring another switch close to another Triac transistor again. When powering a TRIAC from your mains line, the current will begin to flow through the primary coil of a Triac. In lighting applications, this is used for dimming. When the current starts to reverse before all energy has been used, it turns off and switches to flowing in the other direction. When the TRIAC is powered, it will short one of the two lines of your mains cable to the ground, turning on your light. TRIAC dimming is quite effective in reducing power consumptionĪ typical TRIAC controller will have a sophisticated IC that controls the TRIAC, thus maintaining the brightness level. TRIAC control provides a lot of benefits in LEDs lighting 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. TRIAC 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. 13 Phase dimmer What is a leading-edge TRIAC dimmer?
