TRIAC works to switch high voltages that make it a perfect option to utilize in various electrical control solutions. In case the TRIAC dimmer is used in the wrong way with an LED light source, it can lead to the faulty performance of the bulb including humming and flickering and if left unattended, these issues will reduce the lifespan of LED lights over time. Various kinds of TRIAC dimmers are created for resistive loads. When configuring a TRIAC dimmer with an LED bulb and sourcing the TRIAC dimming LED driver, you need to ensure that the TRIAC dimming device is a version of the TRIAC semiconductor device. With a phase control, the TRIAC circuit can regulate the current percentage flowing across a circuit load. In such a case, the circuit enables the high voltage to move across with very low control currents. Activating the TRIAC circuit enables electricity conduction until the fall of current below the edge. TRIAC control operates through a gate electrode when opposite charge voltages are applied. With TRIAC dimming, the chances for half-wave on failure or Hz flicker are less, thus TRIAC dimming doesn’t greatly reduce the lifespan of the LED bulb as compared to Thyristor dimmers that are the most common dimmer. It results in the dimming of the LED light. Quick switch reaction means more released power and slow switch reaction means less released power. The speed at which the switch reacts depicts the released power. Thus, the slow switch reactions result in the conduction of less power and the bulb will be dim. A TRIAC controller for LED light works by adjusting the light intensity.

A trigger tells about the point where the product will begin conducting the electricity particularly splitting up the voltage waveform and hence preventing the voltage to be given at full load. TRIAC dimming controllers function as fast-speed switches and are utilized to regulate the quantity of electric energy moving across the LED light.
The basic working principle is to regulate the angle of conduction for each half-wave of the AC to transform the sinusoidal waveform and then adjusting the effective value of AC to achieve the dimming purpose. It is a physical dimming that begins from AC phase 0 and the input voltage is cut down until the TRIAC dimmer is turned on. They are frequently used as a way of dimming light in different lighting solutions and applications as well as act as a power controller in motors. TRIAC dimmers are semiconductor devices same as a diode. TRIAC circuits can switch high voltages and high current levels in the two components of an AC waveform. TRIAC dimmers have a broad range of applications and are commonly used in AC power control solutions.

However, with the development, new TRIAC dimming drivers have been created for LED lights making the configuration much easier and simpler.
In the past, building an ideal structure of LED lights with phase-cut or TRIAC dimmers has been a challenge. TRIAC dimmers, also known as phase-cut dimmers are probably the most commonly used dimming control systems. When TRIAC is used in lighting systems, it is generally called TRIAC dimming. It is a switch that we use to control the power.
The full form of TRIAC is Triode for Alternating Current.
It will not only enable you to adjust the brightness of the light around your home but also help you to significantly reduce the electricity bills when paired with the LED light source. If this does not work without problems, sometimes the entire LED technology is demonized as not mature.Dimmers have become the fundamental parts of various lighting systems and applications around us. However, this is primarily due to the fact that many people simply assume that LED’s can be dimmed just as easily as the old light sources. However, LED technology is much more complex and brings in some challenges.ĭimming of LED lights is one of the most common difficulties when converting to LED lighting. In the meantime, LED lighting technology has established itself and offers many advantages over the old light sources. These lamps could be easily operated with a dimmer. Old incandescent bulbs and halogen bulbs had an advantage in addition to all their disadvantages.
