There are numerous types of drivers within the market to choose from for LED light fixtures. However, while LEDs are considered constant current driven devices, why do manufacturers offer both constant voltage and constant-current drivers for LEDs and what is the difference? Constant Current LED Driver vs. Constant Voltage LED Driver First, let us discuss
The IEC 61000-4-5 standard and test-method establishes a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges such as lightning. Surge test standards for lightning protection as below, IEC61000-4-5 ranks: Level Open-circuit test voltage 1 0.5kV 2 1.0kV 3 2.0kV 4 4.0kV X Special NOTE X can be any
We will talk about the selection of LED drivers. It seems that it is not difficult to select a driver, but it is indeed difficult to find a proper or suitable driver for an optimized light fixture product. Actually there are multi-steps during the selection of drivers and please check those steps listed carefully if
Hello, today we are going to talk about the flicker, or strobe flicker. Difference of flicker and strobe flicker First let’s try to make the difference of flicker and strobe flicker clear. flicker normally indicates the instability of the light system, which can be obviously noticed by human eyes. And the flicker frequency is unstable
After launching 400W LED drivers, uPowerTek launches constant current 320W LED drivers today to meet the need for large scale lighting system requiring high power with high-voltage output. BLD-320-C follows the high performance and high reliability design of the other LED drivers and offers 5 year warranty. The whole series provides various models equipped with
uPowerTek launches constant current and high voltage output 400W LED drivers in the LED lighting industry. Since the demand for LED lighting applications adopting the design of a high-voltage single route with LEDs connected in series continues growing, uPowerTek is pleased to unveil the new 400W~BLD-400 series LED power supply in order to meet the
Today uPowerTek has launched the new 150W LED driver series to compete in the high end street light market. The features include the 10kV surge protection, 12Vaux with 300mA capability, dim to off function and much compacter packaging compared to the competitors. This family covers 500mA-6.3A with constant current output, and 24-48Vdc with constant voltage
Today uPowerTek launched the new 75W LED driver series to compete in the high end street light market. The features include the 10kV surge protection, 12Vaux with 300mA capability, dim to off function and much compacter packaging compared to the competitors. This family covers 300mA-6.3A with constant current output, and 12-48Vdc with constant voltage output.
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
