  Led Driver for tube light From:  www.hzleddriver.com          LED tube driver  is a LED driver power supply, it is the most important part of an LED tube lamp. improper choice, LED tube lamps can not play a performance, even can not be used normally.         Led Tube driver has two kinds built-in and external, the built-in is a long strip, that can be directly inserted into the semicircular tube inside. The built-in led driver is also divided into two types: isolated and non-isolated. Non-isolated means that there is a direct connection between the load end and the input end, and there is the risk of touch shock, especially when the load is high voltage.         The non-isolated type is most commonly used at present, which is directing step-down the power supply, as shown in Figure 1 ( HAD028CXN ). The non-isolated constant current led driver power supply has the advantages of simplicity and high index, an...

  What is the led driver 3 in 1 dimming? From:  www.hzleddriver.com         LED driver three-in-one dimming refers to LED 0/1-10V dimming, PWM dimming, and adjustable resistor dimming in three ways. 1. LED driver three-in-one dimming:  0/1-10V dimming         The power supply is designed with a control chip. When connected to a 0-10V dimmer, the output current of the power supply can be changed through the 0-10V voltage change. For example: when the 0-10V dimmer is modulated to 0V, the current drops to 0, and the brightness of the light is turned off (with a switch function). When the 0-10V dimmer is adjusted to a maximum of 10V, The output current will also reach 100% of the power output, and the brightness will also be 100%. (The output voltage is unchanged).1-10V dimming principle: As explained above, only the dimmer is 1-10V: when the resistance dimmer is adjusted to the minimum 1V, the output current is also changed by 10%, suc...

  How to install an Led Driver? From:  www.hzleddriver.com         With the development of LED lighting, people gradually understand one of the key components of the LED lighting systems ---  Led Driver . When we have an led driver, we will be troubled about how to install this led driver. The following content can help you know to  install the led driver . Led driver installation steps ： 1. First, carefully read the relevant parameters of the led driver, such as voltage, current, etc., to ensure that the parameters of the led driver match the LED. 2. Consider the IP level of the Led driver to determine the external environment where the led driver is located. If the led driver is installed outdoors, it needs to have a certain waterproof performance. There are led drivers specially designed for outdoor environments, such as the model  HPD036CXI IP65 waterproof led driver , which is designed for outdoor lighting. 3. Identify the P (positive) a...

  How to judge the quality of Led Driver? From:  www.hzleddriver.com   A few simple ways to identify the quality of an Led power supply: 1.  PFC (Power Factor Correction)         Now some countries will require at least PF>0.7, but not necessarily high PFC is good, but also consider the overall oblique wave (small), ripple (small), interference (low), because some manufacturers deliberately make the PFC very high but ignore the electromagnetic compatibility part. 2.  Conversion efficiency         Conversion efficiency, the value, and the stability of the deviation. For example, in the working voltage range of AC170-250V, you can try to debug it from 170V-250V. The voltage changes from low to high constantly, so that you can see on the power meter whether the fluctuation of "conversion efficiency, PFC" is large to prove its stability. 3.  Whether the temperature rise of the power supply is high       ...

Today, I found a video on How To Choose The Correct LED Driver For Your LED Lights. I feel The content is very good and want To share it.  From: https://www.youtube.com/watch?v=Fqe-Jegaybg

  What factors affect the work of led driver? From:  www.hzleddriver.com         With the development of the LED industry, LEDs of high energy saving, long life, and superior performance of environmental protection have been widely recognized, and LED drivers are more and more widely used. But there is the various  led driver power supply  on the market, so how do we  test LED drivers , and how to distinguish the quality of LED power supply?         First of all, we need to know what the most important parts of a led driver are: 1) The core of the LED light driver is IC, the quality of IC directly affects the whole LED light driver. 2)  led power supply circuit diagram  design and welding process for power supply products, such as component layout, bright and straight solder joints. adjustable constant current led driver 3) Transformer -- determine power and temperature resistance, such as whether the coillead is...

  How to replace the LED Driver? From:  www.hzleddriver.com         It is a difficult procedure for replacing  LED driver . Usually when an LED fixture broke is due to driver problems. So only replacing driver will save your cost instead of purchasing a new whole fixture。       When you need to replace the LED driver         It’s time for you do the retrofit when two conditions appears. Overdriving, when the driver transfers power exceeds the normal value which a LED can receive. You can easily judge by observing the higher brightness of the fixture than others. The other sign is underdriving, which means the driver can’t send enough power to the LEDs. Usually lower brightness will appear when such circumstance happens.       What you need to know when replacing your driver         Things you should be aware when do the driver replacement. Before you do the replacement, the...
