LED Driver- What is it?
The lighting method of LED technology is entirely different from other lighting methods. Unlike other conventional lighting types, LEDs require LED electronic drivers to control their electrical current. A constant current electronics LED driver, as the name suggests, allows a constant current flow to LEDs. The primary advantages of these include saving energy and the long life of intended function, which as a result saves money. Electronic drivers are used to control several components, and LED is one of them.
It is a device that does exactly what its name says. It drives the current flow to LED bulbs. You must be thinking about why LED bulbs do need a driver. Yes, these bulbs are energy efficient and do not take much power to work- often between 2V and 4V. They need something to convert AC into DC for them. Electronic drivers also keep the bulb going in case of power surges and keep them safe from overheating.
Therefore, these drivers do not only act as a current flow management system but also as a protective buffer.
Types of electronic LED drivers
If you look into the types of pin electronic drivers for LEDs, you’ll find two different types- constant current and constant voltage. Both types have different roles in different situations. As you must have already guessed, the primary difference is that one is to manage the voltage, and the other is for current.
Constant current LED drivers are essential when your LED lamp does not have an inbuilt driver.
Advantages of constant current LED Electronic drivers.
A constant current ATE pin electronic driver for LED helps you avoid disturbance of Absolute Maximum Current Rating (AMCR), which may certainly make your LED undependable over time. The constant current drivers also assist in reaching the luminous levels that are predictable. This feature helps the most when the LED bulbs are being used in a theatre or a stage. It is important to keep the luminosity levels constant and similar throughout the board in such situations.
Another good thing about these drivers is the constant flow of electricity- just like the name predicts. The other thing to note is that not all LEDs you purchase come with these electronic drivers. You may certainly dim the light of an LED without a driver, but it would not ensure the same luminosity as other LED bulbs connected to a constant current LED driver.
Moreover, based on where you have connected it to, there may be a chance that it is receiving excessive power than usual. While you may expect these bulbs to hold such power in some situations, they may also get worn down over time. That is what explains the AMCR limit. Therefore, using a pin electronic driver becomes necessary for daily LED consumption.
Purchasing an LED Driver
When you are out there to purchase an LED driver, be clear that there is a specific difference between constant current and constant voltage drivers. You have to specify your needs to the retailer to pick the right driver. While constant voltage electronic drivers may be used in some applications, they may fluctuate the luminosity. However, using constant voltage drivers instead of constant current does not make a difference in some other cases.
The situations where you need a constant current flow without fluctuations, the constant current pin electronic drivers, are an ideal choice.
