Now both of uPowerTek’s constant voltage and constant current LED drivers are equiped with 10kV lightning protection function. uPowerTek use the advanced surge test equipement to test the high reliability and high surge protection LED drivers. Besides the 10kV surge test function, the LED drivers are designed with IP67 waterproof function, which makes it possible
uPowerTek launches it’s new generation BLD series LED drivers, this series LED drivers are equiped with 0-10V dimmable function, and it also supports dim to off function, many customers requires this function for intelligent applications. uPowerTek’s IP67 0-10V dimmable LED driver can dim to off at 0.4V, and dim on at 0.7V, which can be
Intelligence is now everywhere, the phone, the households, the white appliances, watches, and general lighting as well. No matter whether you are used to it or not, it is really the trend，and no matter whether you accept it or not, it is changing your life. Today we are going to talk about intelligent lighting control. Actually
LED lighting industry has been booming for several years and it is well recognized that LED driver is the key component of LED lights. Usually the quality and right application of LED driver determines the reliability and life of the whole light fixture. So it is very important to make sure that fixture designers are
What is PF of LED Driver? The power factor of a power supply is a ratio of the real power to apparent power of the power consumed by the supply. It is expressed either as a number between 0 and 1 or as a percentage between 0 and 100%. Real power is the actual power
Hello everyone, Today we will talk about the relation between power factor and load. As we know that power factor is a very critical parameter when we are designing the lights, and a key value which evaluates the pollution caused by the electrical device to the electricity grid.Normally it has to be over 0.9 according
There are a number of reasons why it is advisable to use LED drivers with high efficiencies. Benefits of high efficiency LED drivers The first, of course, is the cost benefits of high efficiency drivers. The less energy that is required to provide the desired luminous output, the less it costs to power the fixture.
China’s decade old streetlight standard GB7000.5-2005 has been replaced with a new standard GB7000.203-2013 that has become effective as of July 1, 2015. Changes in the new and old lighting standards will require manufacturers to make certain adjustments in their outdoor luminaire designs, according to a Shanghai Entry-Exit Inspection and Quarantine Bureau’s Electromechanical Engineering Department
Conventional AC-DC power supplies and DC-DC converters provide an output that is regulated toprovide a “constant-voltage.” However, LEDs work most efficiently and safest with a “constant-current” drive. As a result, many new devices have been developed to provide this type of LED drive. LED power sources that provide a “constant-current” output have typically been referred
DALI is a very popular dimming and control technology in the world, but there are two many concepts and new technologies in recent years, so we write this article to help you understand the DALI dimming technology and help you to be a DALI expert, we believe it will help your work, keep reading. 1
LED lighting systems continue to soar as we can see everywhere. But do you know that there is a driving force as the key component behind the LED fixtures? They are the LED drivers. The LED power supply regulates the LED fixture’s power (voltage or current), thus precisely controlling the light output. In addition, high quality LED
LED lighting penetrates everybody’s life, becoming more intelligent and more sophisticated. When designing high quality and excellent luminaire, the design engineer must carefully understand the LED Driver since it is the heart of a light fixture. This article describes the most frequently used LED driver concepts and provides the methods to select a suitable and
