What is a LED driver for LED lighting?
20 Dec, 2018
A LED power driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An Triac Dimmable LED Driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED as its electrical properties change with temperature. LED drivers do exactly what it sounds as if they do – that is, they drive the power that’s s...

Why do LEDs flicker?
10 Jan, 2019
All mains-powered light sources flicker – whether halogen, fluorescent incandescent, or LEDs. In the UK, mains electricity is an alternating current (AC) power supply, delivered at a frequency of 50 hertz. Which means the electric current that powers your lights – any lights – switches backwards and forwards 50 times each second. We didn’t used to notice it with our old incandescent...

What is PFC function power supply?
17 Jan, 2019
PFC is the acronym for power factor correction or power factor controller. It minimizes the amount of reactive power produced by computers. Active PFC uses electronic circuits in efficiently distributing power to devices connected to the power supply. Power Factor Correction. Many loads are highly inductive, such a lightly loaded motors and illumination 24 volt LED Transformer and ballasts. You ma...

When Do I Need a “Constant-voltage” LED Driver?
25 Feb, 2019
Most commercially available LED “light modules” are constructed by connecting a number of LEDs in series orinparallel to form cluster or string configurations. In cases where these lights modules include a constant-current driver as part of the assembly, an external “constant-voltage” driver or power supply is required. Low cost LED circuits control the current flowing through the LED with a simpl...

What is a led driver
23 May, 2019
Due to increasing energy regulations, most people are familiar by now with the long life spans and energy savings associated with LEDs, or light-emitting diodes. However, many are not aware that these innovative light sources require specialized devices called LED drivers to operate. LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for lo...

What is PFC on led constant voltage power supply
23 May, 2019
Power factor is a factor that measures the efficiency of electrical equipment like led constant voltage power supply. The low power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is large, thereby reducing the utilization rate of the device and increasing the line power loss. By improving the power factor, the total current in the line and the ele...

What is the MTBF?
23 May, 2019
MTBF, that is "Mean Time Between Failure", It is a measure of the reliability of a product, especially for electrical product, the unit is "hour". MTBF reflects the time quality of the switching power supply and the ability to reflect that the led driver remains functional for a specified period of time. To be specific, it refers to the average working time between two adjacent...

How LED lighting works with lighting system
23 May, 2019
There are different opinions on how LED lighting fixtures can be equipped with lighting control systems. The most critical part is to choose a dimming power supply. Different environments and needs, the dimming method is different, which is the common point of each dimming project. For example, the project did not have a dimming effect at the beginning, but a dimming function was needed in later p...

What is the difference between a driver and a power supply?
15 May, 2019
LED power supply sources that provide a "constant-current LED power supply" output have typically been referred to as LED drivers. In the past, AC-DC power supplies that provided a regulated “constant-voltage” to LEDs were referred to as LED power supplies.Today, the terms "LED driver" and "LED power supply" are used interchangeably. Also, it depends on the type of LED....
