LED Driver

What is an LED Driver?

An LED driver is a device that does exactly what it sounds like — it drives power to one or more LEDs. LED drivers are also called LED power supply or LED transformer.
As we mentioned before, one of the benefits of LEDs is that they are energy efficient – they don’t require a lot of electricity to run them. LEDs actually operate on DC at reasonably low voltages – usually between 2V and 4V. Because of this, they need something to convert AC to DC for them and help protect them from any power surges that might occur, causing the LEDs to overheat and cause problems. The LED driver is not only a current management system but also a protective buffer.

What is a Switched Mode Power Supply (SMPS)?

A switched mode power supply (SMPS) designed for LED lighting applications is an LED driver that uses a switching regulator to convert the rectified DC power into a predetermined magnitude of DC power. SMPS LED drivers provide the most efficient and technically mature solution to LED current control. Today’s LED lighting products, in particular those designed for high end applications, place high demands on the driver’s ability to efficiently convert electrical power from an AC source to a DC load with outputs matched to the electrical characteristics of the LEDs. Despite the increasing cost and form factor restrictions in LED luminaire design, switched mode power supplies are still the most preferred type of power converters to drive high performance LED luminaires.
Now all the LED drivers in the market are switched mode power supply.

DMX512 Dimmable LED Driver

LEDYi DMX512 dimmable LED Driver with NFC/RDM function for setting address, including with constant voltage 1 to 5 Channel
30W to 300W. Setting fine adjustment output voltage by NFC; Constant current 1 to 2 Channel 10W to 40W, Setting output current
by NFC.
Based on DMX 512 protocol, this series will be provided with RDM/NFC function. The Remote Device Management Protocol( RDM), It
can realize the function of remotely assigning addresses, reading device information, devices recognition, and personalizing
Near Field Communication(NFC) is based on NFC wireless transmission protocol. It can set the DMX address for the power supply
and adjust the output voltage or current of the power supply without power on.
The RDM and NFC functions eliminate unnecessary holes in the power supply and increase the waterproof performance of the
power supply.
