High Quality Led DriverYou have just returned from a hardware store with grand dreams and a large number of LED strips. You opened all the packages, and then-what is it? How do these things work? How do you open them? Dimmable LED driver supplier shares this article for you.

Welcome to the world of LED drivers

LED lights require a special device called an LED driver to turn on and operate. The function performed by the LED driver is similar to the function of a ballast for a fluorescent bulb. The driver converts the line voltage into power suitable for LED operation. In addition, since the electrical characteristics of the LED will change with temperature fluctuations, the driver will adjust and maintain a constant amount of current.

What does the LED driver do?

High quality LED driver is mainly used for three purposes:

Most households use 120-277V AC, but LEDs rely on low-voltage DC to work. Therefore, the driver changes a higher voltage AC current to a lower voltage DC current to match the voltage at which the LED lamp needs to work.

The input voltage of the driver must be the same as the voltage required by the driver. Otherwise, voltage changes will cause flicker or flicker.

The common method of controlling the light output of LEDs is through pulse width modulation. When the LED bulb is dimmed, especially at the low end of the light output, it may cause flicker.

Does the LED need a driver?

Most leds require a driver, and a few are designed to run on AC current.Although the LED bulbs you screw into the fixtures may not look like they are, they actually have internal drives, just as screw-in CFLS have integrated ballasts.Most household leds can directly replace incandescent, halogen and CFL bulbs with Either An E26 / E27 or GU10 / GU24 base, and come with an internal drive.

These are the bar lights that people trip over.The LED strip also requires a drive, but you can buy the strip separately from the drive, and a drive can power multiple LED strips!

Is the LED a bad light or a driver?

Here's another tip: If your LED lights are dimming, it could be a driver problem - not the LED!The drive operates at higher internal temperatures, so the LED life can be shortened if the bulb is used in a closed fixture or in a hot garage.The drive may fail before the LED chip's solid state junction fails.This is why leds work better than CFLS at low temperatures.They glow instantly (technically faster than incandescent bulbs), whereas similar CFL bulbs may need dim lighting to warm up to full light output.

So, what do you do now that you have your LED band set and no drive?The only solution is to choose an ultra-thin LED Driver for your lighting.
