How to select a suitable qualified LED driver?

LED lighting penetrates into everyone's life and becomes more intelligent and exquisite. When designing high quality and outstanding lamps, the design engineer must carefully understand the LED driver because it is the heart of the lamp. In this article, LEADPOWER will describe the most commonly used LED driver concepts and provides a method for selecting a suitable qualified LED driver. 1.What are LED drivers LED drivers, also known as LED power supplies, typically convert AC (AC) to stable DC (DC) output, since light-emitting diodes (LEDs) are a unique component that only accepts DC input. 2. To describe the size of the LED drives External LED driver with an internal LED LED drivers can be built into the lamp (inside), placed on the surface of the lamp, or even on the outside of the lamp (outside). Most low-power indoor lights, especially bulbs, use indoor LED drivers to make cheaper and better-looking products, but external LED drivers are commonly used for downlights...

How to use LED drivers properly?

According to the characteristics of the power grid, the requirements of LED characteristics and related LED products, the following points should be taken into account when selecting the LED drive power supply.   According to the LED current and voltage characteristics, it is more ideal to use constant current drive. It can avoid the change of LED forward voltage and cause current changes, while the constant current makes the LED brightness stable. In addition, the LED luminous flux is inversely proportional to the temperature, so the use should minimize the power supply heat and design a good cooling system. Thus reducing the ambient temperature of LED work. In order to ensure the overall life of LED products, the junction temperature of LEDs must be controlled within a certain range, that is, to control the working environment temperature of LED products.   Before installation, confirm whether the rated input voltage of the power supply is within the range of t...

Learn about LED drivers and how to choose the right one?

"LED drivers can be the confusing part of LED technology. There are so many different types and variations, it can seem a little overwhelming at times. That's why I wanted to write a short article explaining these varieties, how they differ, and what to look out for when choosing an LED driver for your lighting application"You may ask what is an LED driver? An LED driver is an electronic device that regulates power to an LED or LED strip. It is a critical component of the LED circuit, and operation without it will cause system failure Things to consider before selecting an LED driver What type of LEDs are being used and how many? Find out forward voltage, recommended driving current, etc. Do I need a constant current LED driver or a constant voltage LED driver? We go over constant current vs. constant voltage here. What type of power will be used? (DC, AC, batteries, etc.) Running from AC? See how an AC driver will benefit you! What are the...

5 Important Factors When Buying LED Drivers

LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for low-voltage bulbs: they provide LEDs with the correct power supply to function and perform at their best. If you read our previous article on whether or not your LED requires a driver, you’ll already know that all LEDs require a driver and that the question you should really be asking is whether or not your LED requires an external driver. You’ll also know that there are two main kinds of external LED drivers, constant-current and constant-voltage, and that the driver you need depends on whether or not your LED light source already includes a constant-current driver within the light (if so, you would need a constant-voltage driver; if not, you need a separate constant-current driver). Now that you’re certain your LED light requires an external driver as well as what type, it's time to narrow down to the specs you need to consider when making a...

How to choose LED display power supply?

1. Look at the appearance process to choose the LED display power supply. A good power supply manufacturer is also very strict with the workmanship process, because only in this way can the batch consistency of the products be guaranteed. An irresponsible manufacturer produces a power supply whose appearance, tin surface, and arrangement of components will never be good.2. Select the LED display power supply from the full load efficiency. The efficiency of the power supply is a more important indicator. The high-efficiency power supply has a high energy conversion rate, which not only meets the requirements of energy conservation and environmental protection, but also saves electricity and money for users.3. The output voltage ripple of the constant voltage power supply. The size of the ripple has a great influence on the life of the electrical equipment, and the smaller the ripple, the better.4. Observe the temperature rise when the power supply is working to select the LED display p...
