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...

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 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...

Why do you need a driver for LED lights?
07 May, 2019
LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps). The two main types of LED drivers are Constant Voltage and Constant Current to power up the LEDs. Constant Volt...
