Everything about LED Driver

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 qualified LED driver.1. What is LED driverLED Driver, also named as LED power supply, converts typically Alternating Current (AC) into a regulated Direct Current...

Removing the LED Light Flicker by Correct LED Driver Selection

It is a trend in the lighting industry to replace traditional incandescent and fluorescent lamps with more efficient and longer-life LEDs. However, since it is directly connected to the AC line, like the traditional pioneers, there may be a risk of 100Hz or 120Hz flicker due to the drive current ripple at the output of the power supply, although most of the time this may make consumers feel uncomfortable with humans. The eyes cannot notice them. LED and lamp...

Can You Put LED Drivers In Parallel?

Now more and more high power luminaires are utilized for horticultural or industrial lighting applciations to realize better control and reduce installation and maintenance cost. To achieve that, designers have two options, one single high power LED driver and the other is multiple LED drivers in parallel. Yes, it is possible to put LED drivers in parallel. However, although the possibility exists, putting LED drivers in parallel is not the best practice.Kindly note that putting LED drivers in parallel...

The Difference between DALI DT8 and DT6

Digital Addressable Lighting Interface (DALI) is a protocol for digital lighting control that can easily install a robust, scalable, and flexible lighting network. DALI is currently the most commonly used optical digital protocol. When talking about DALI control, we often hear people say DT6 or DT8. What do they mean? This article will take you to understand their definitions and differences.DALI Device TypesThe DALI protocol is maintained by the Digital Lighting Interface Alliance (DiiA), a global alliance of...

What are Dimming Curves and How to Choose?

The LED lighting industry continues to adopt the concept of dimming in LED lighting fixtures. Hence dimmable LED drivers constantly get industrial attention.As we know, dimming fulfills visual needs and saves energy in LED lighting fixtures. As a result, when we analyze the concept of dimming, we cannot neglect the subject: dimming curve.Dimming curves are parameters or function images that specify the response of dimmers voltage output to control signal input.The dimming curve shows how electrical parameters of LED...

Different Concepts about Class 2 and Class II LED Drivers

Choosing a power supply for your project can be challenging and tough because there are so many options and regulations to follow depending on where your project is located.You may come across regulations that need a Class 2 or Class II power supply while working on your project, and it's particularly challenging when deciding between Class 2 and Class II. These two classifications may sound similar, yet they mean very different.Both are significant classifications, though, because they deal with the power...

What are the protections of LED drivers?

All LED drivers need various protections to prevent failures to protect the system where power suppliers are utilized. There are many types of protections related to voltage, thermal and current which improves the reliability and functionality of LED drivers.However, these protections have a list of specifications. This blog post will explain what they mean and how they help your LED drivers.LED Driver Thermal ProtectionPower supplies use over-temperature protection (OTP) to disconnect or lower the power from an electronic circuit if...

How Many Grow Lights Can a 0-10v Dimmer Control?

LED grow lights are becoming the centre of attention to overcome the seasonal changes and fulfil the increasing food, indoor gardening or medicine demand since grow lights allow you to cultivate a wide range of plants during any time of the year and any climate in the world.Unlike any other LED lights for the human beings, LED grow lights’ density is always much higher thus there are more lights connected to a single dimmer while there are many type of dimmers...

Top Level Global LED Driver Certificates

LED driver helps the LED lighting device be more readily installed, efficient, robust, and perform better, so it should be a dependable standardized product to have their LED drivers certified. Certified LED driver guarantees the safety, dependability, and quality of the device.  The certification procedure has become a criterion for confirming product quality and identifying respectable manufacturers. Though products without certification marks may have low production costs, they will only be functional for a short period. Eventually, the cost...
