How does a DALI driver work?
14 Sep, 2021
Light emitting diodes (LEDs) as an efficient low-consumption lighting technology are being used increasingly in many applications. The move to LED lighting is also changing the way the lighting control systems are designed. Currently, most electronic drivers and other digital lighting devices implement the Digital Addressable Lighting Interface (DALI) standard. Most of the constant vo...

What role does lighting play in office lighting?
23 Sep, 2021
Different lighting brightness and color temperature give people different psychological feelings, and their influence on atmosphere creation and emotions is different. Warm color light can give people a feeling of warmth, warmth and harmony. The cold light can give people a sense of calm, shady, and coldness. And this requires dimming led driver to help 1. Appropriate illumination Illu...

What are the characteristics of PWM dimming?
27 Sep, 2021
PWM dimming is currently a mainstream dimming technology used in LED dimming power supply products. In the circuit of the analog signal, the brightness change of the lamp is controlled by the digital output. Compared with traditional analog signal dimming, this dimming method has many advantages. The basic principle of pwm dimming led driver can be understood as connecting a ...

Questions of LED lights and led driver in project
08 Oct, 2021
*Why can't the lamp cup (tungsten wire) of the same power be lit with the same 110v dc led driver? When the lamp cup is in the cold state, its resistance is very small, that is, when the rated voltage is applied to the lamp cup, a large starting current is required immediately before lighting. When the lamp cup is lit, the temperature rises, the resistance value increases sharply, and the current ...

How to deal with the problem of LED dimming and flickering?
29 Nov, 2021
Normally, the human eye can perceive light flicker with a frequency of 70 Hz, but it will not perceive it at a frequency higher than this frequency. Therefore, in the LED dimming driver lighting application, if the pulse signal has a low frequency component with a frequency lower than 70 Hz, the human eye will feel flicker. The flicker is generally caused by the loop current not reachin...

Does LED drive power determine the life of LED lamps?
17 Dec, 2021
Constant current source drive is the best way to drive LEDs. It uses constant current source to drive, no need to connect a current limiting resistor in the output circuit, and the current flowing through the LED is not affected by external power supply voltage changes, environmental temperature changes, and the discreteness of LED parameters. Therefore, the current can be kept constant and the va...
