An LED Driver Power Supply is needed to run LED's properly
06 Dec, 2018
LED Driver SMPS are used to function the LED. They are used to convert the input voltage to a voltage which is considered optimum for the LED. LED Drivers Power Supplies are usually switching mode devices that convert the input voltage (Typically 100-265VAC or 12 VDC) into a voltage at which the current drawn by the LED's is equal to its drive current. Due to increasing energy regulati...

What is the purpose of a LED driver and how does it work?
11 Dec, 2018
An 12v DC LED Driver is needed to run LED's properly. Unlike most electronic devices, LED's are current driven devices, not voltage driven ones. Even a minuscule change in voltage can lead to a huge change in current. Hence, it is important that the drive current is regulated and not the voltage. 24V Constant Voltage LED Power Supplies are usually switching mode devices that convert the input volt...

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 do you mean by constant voltage?
23 Jan, 2019
A Constant Voltage LED Driver 12V & 24v can be used to power LED lights that have constant current drivers already within the system or resistors . 'Constant voltage' refers to the ability to fluctuate output current to maintain a set voltage. So you need some type of constant voltage power supply that can convert your AC household voltage down to a safe DC voltage. There are many things that ...

Advantage of triac dimmable led drivers
19 Jun, 2020
Using a triac dimmer connect to the input of “N” of the triac dimmable led driver for dim the LED lamp. During the conduction process of the triac changing the voltage division ratio of the internal adjustable resistor and changing its conduction angle, the effective value of the output voltage can be changed to achieve dimming function. In addition to triac dimming mode, there are leading edge an...

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 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...
