What is the dimming compatibility of triac power supply?

When it comes to the compatibility of triac dimming, one of the common problems is that the maximum and minimum firing angles produced by the phase-cut dimmers are generally inconsistent during dimming, which results in the dimming performance of LED lamps. Differentiation. Different brands and different product models have a very large range of trigger angles. As a result, their on-time and power...

What is a triac dimming power supply?

Triac technology is a technology with more than half a century. After the Triac dimming technology, the lighting industry has adopted 0/1-10V analog dimming, DMX512 and DALI and other PWM digital dimming protocol technologies. However, Triac dimming technology has its irreplaceable reasons. One is due to historical inheritance, and the other does not require signal lines and does not need to chang...

Basic knowledge of LED lights

LED lights under the control of dali dimmable led driver are called semiconductor light-emitting diodes, which are made of semiconductor materials. Semiconductors can be divided into P-type semiconductors and N-type semiconductors. N-type semiconductor with extra electrons, P-type half The conductor has additional "holes", electrons can move between the holes, and the flow of electrons will genera...

What is the "Type HL" LED Driver?

UL announced the launch of "Type HL" LED driver certification for hazardous locations on July 26, 2013. The hl led driver refers to the relevant requirements of ballasts, and is added to the standard "UL8750 LED devices used in lighting products" as a certification requirement resolution (CRD). The appendix SB of UL8750 lists specific requirements for "Type HL" strip led driver. The...

How do 0 10v dimmers work?

0-10v dimming is divided into: 0/1-10v, PWM, adjustable resistance dimming. 0/1-10v dimming principle: The power supply is designed with a control chip. When a 0 10 volt dimmers or 1-10V dimmer is connected, the output current of the power supply can be changed by changing the voltage of 0/1 -10V. When the 0/1 10v dimmer switch is adjusted to a maximum of 10V, the lamp will output at full brightne...

What's a triac dimmer?

The dimmer has become an indispensable part of dimming lighting system. Not only does it allow users to control the brightness level around the house, but it can also do a good job in helping reduce electricity bills at the end of the month. The triac dimmer, also called phase-cut dimmers are one of the most usual types of dimming control system use in most applications. The triac dimming system c...

What are the benefits of triac dimming in application life?

When the lamp needs to be triac dimmer by the thyristor signal, the input voltage waveform in the circuit deviates from the sine wave due to the change of the thyristor conduction angle, which also changes the effective value of the input voltage, and realizes triac dimming led driver by changing the voltage. However, what matters here is that during the thyristor conduction process, a switch in t...

What are the advantages of DALI dimming applications?

DALI dimmable is currently the most advanced lighting control system in the world. It can control each lamp individually, realize linear control of brightness, color temperature, color, etc., control the lamps in groups, and set different scene modes and plans. 1. Precise grouping scene control: DALI dimmable led driver sends out a digital signal when dimming, which can realize disturbance-free co...

How does triac dimming?

When the lamp needs to be dimmed by the triac signal, the input voltage waveform in the circuit deviates from the sine wave due to the change of the triac conduction angle, which changes the effective value of the input voltage, and the dimming is realized by changing the voltage. During the triac turn-on process, a switch in the triac potentiometer can adjust the voltage divider ratio of the inte...
