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....

Do you need a LED transformer for LED bulbs?
30 May, 2019
All LED bulbs require a 'driver' (a special type of transformer) to work properly. Mains voltage LEDs (such as GU10 and B22 bulbs) have the driver built in to the bulb. ... If you are replacing existing incandescent 12V bulbs you will need to replace the transformer with a special LED driver. Due to increasing energy regulations, most people are familiar by now with the long life spans and energy ...

Are your led driver flicker free?
06 Jun, 2019
Flicker can be defined as the perception of visual unsteadiness induced by a light source which fluctuates with time for a static observer in a static environment. LED Flicker is caused by voltage ripple at the output of the AC power supply. Furthermore, a stroboscopic effect is the change in motion perception induced by a light stimulus whose luminance or spectral distribution fluctuates with tim...

What is a LED driver for LED lighting?
17 Jun, 2019
An LED driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An 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. An LED driver is a self-contained power supply which has outputs that are matched to the electrical characterist...
