Choose a Led Driver for Street Light From: www.hzleddriver.com With the development of the led lighting industry, the development of commercial led street lights is also getting faster and faster, and the advantages brought by led as an outdoor lighting source are becoming more and more prominent. Good power saving rate and lighting comfort make the development of led outdoor lighting more and the better. How to choose the right led street light power supply , you need to consider a variety of factors. Here are the factors to consider when picking the best-led driver for the led street: 1. High-quality components Street lights are in severe weather such as high temperature, high humidity, and lighting strikes, so the quality requirements for led drivers are very high. The quality of the led driver will affect the life of the led street lamp, and the quality of the led driver will be affected not only by good design but also by the reliability of the led driver power

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, and its output current can be determined according to the number of LED series 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%, such as when it reaches 10V (adjusted to the maximum), th

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) and N (neutral) wires of the power and discon

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 The higher the temperature of the power supply itself, the greater the d
