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...

Eight tips to improve the efficiency of LED power supply
05 Jan, 2021
1. The main current loop PCB should be as short as possible. LAYPCB experience, and layout, this is nothing, the quick way is to look at the works of big factories. 2. Optimize the design of 300w LED transformer parameters to reduce eddy current loss caused by ringing. This is more difficult. First, you must master the basic knowledge...

What is a 12V dimmable driver?
09 Mar, 2021
Regularly 12v constant voltage led driver is not designed for dimmer switches, and perform unpredictably when dimmed. At best, you might have some measure of dimming control with inconsistent dimming or flickering, at worst, your lights might not work at all. The solution is a power supply designed for use with a dimmer switch : a dimmable driver. 12V dimmable drivers offer superior dimming a...

What is the connection way between LED and LED drive power matching
06 May, 2021
We already know very clearly that there are only two ways to drive the LED: Constant current type: the current does not change and the voltage changes within a certain range (varies with the load) Constant voltage: constant voltage and current changes within a certain range (varies with load) There are three ways to cooperate with LED lights: series and parallel. In Series: The LED driver i...

What is the LED drive power supply?
24 May, 2021
LED drive power supply: a voltage converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Under normal circumstances, the input of the LED drive power supply includes high-voltage power frequency AC (ie city power), low-voltage DC, high-voltage DC, low-voltage and high-frequency AC (such as the output of an electronic transformer), etc.; The out...
