Application of dimming power supply

The dimming power supply achieves the LED dimming function by controlling the output of the current, voltage and frequency of the LED. The brightness, color temperature, and color of the light can be adjusted according to the requirements of human eye comfort, environment and scene, etc., which is more powerful than ordinary power supply, and is more energy-saving and environmentally friendly. The...

How does dimming power affect and change our lives?

Behind every beam of dazzling LED light is the support of the power supply. As the hero hidden behind the lights, the power supply is often inconspicuous, but its role is very critical. The emergence of dimming power supply is a very important part of the development process of power supply, and its emergence has realized the control and change of light. The dimming power supply adjusts the bright...

Introduction to the principle of 0-10V dimming power supply

The power supply design has a control chip. When the 0-10V dimming power supply is connected, the output current of the power supply is changed through the 0-10V voltage change, and the light is reduced. For example: when the 0-10V dimming power supply is modulated to 0V, the current drops to When it reaches 0, the brightness of the light is also off. When the 0-10V dimming power supply is adjuste...

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...

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...
