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...

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 ...

*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 ...

Wireless technologies have been rapidly developed during recent years. Smarts keep up with trends, technology and launch a wide range of 12vDC, 24vDC or 48vDC 60W to 200W WIFI, Bluetooth,Zigbee wireless dimmable LED driver.  Zigbee and Bluetooth are both wireless communication technologies. ZigBee's transmission distance varies from a few hundred to several thousand meters depending on the tr...

Outdoor lighting, especially street lights and tunnel lights, are difficult and expensive to maintain. Therefore,led driver 75w not only require high reliability and high protection level for these applications, but also need a long service life, so that the lamps can run at least 5 year. This article describes how to ensure the long life of the led driver 25w. Choose a long-life capacit...

I guess you have noticed that SMARTS launch a new series of flicker free  selectable multi-current dimmable led power supply with dip switch in DMX, 0-10V, Triac, 2 in 1 (triac + 0-10v) dimming. Some of you are wondering what is it used for? Are there big markets to sell? The answer is yes, of course. Let’s take 10w selectable triac dimmable led drivers as an example. It has 8 outpu...

 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...

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...

In order to save energy, LED has been widely promoted, but LED needs power supply, and its quality will directly affect the life of LED, so how to choose an LED driving power supply is the top priority.   The drive circuit directly affects the life of the LED The dimming LED drivers we are talking about include digital drivers and analog drivers. Digital drive refers to di...

Give up high-power and super-power, choose a high-stability small and medium-power power supply   Because the greater the power, the greater the amount of heat generated, and the more compact the components inside, which is not conducive to heat dissipation, and the temperature is the culprit for the failure of the power supply. Furthermore, low-power 12v 200w led driver power suppl...

First, determine whether the lamp is constant voltage or constant current, which can be judged according to the parameters marked by the lamp. If the marked input voltage is DC12V/24V, it is a constant voltage lamp, then select a constant voltage dimming led power supply for dimming, if the lamp marked input current is a constant value, such as 600mA, the input voltage is a range va...

The first advantage of constant current power supply is strong stability. Strong stability is a problem that families are very concerned about. After all, this has a lot to do with the safety of the family. It must be a safe current to make family members feel more at ease. No matter how big the output voltage of the constant current led power supply is, it will never change, and the stabilit...
