How Does A LED Driver Transformer Works?
LED drivers are intrinsic to the
functioning of LEDs, and contribute to the huge difference between the way LEDs
work and incandescent or fluorescent lights work. Quite simply put, LEDs
function on low voltage direct current, whereas all residences and commercial
establishments receive high voltage alternating current. The LED drivers
convert the power to the desired type and range and ensure that the LEDs are
protected from sudden fluctuations. This, in a nutshell is what the LED drivers
perform. Here is a detailed overview of the role of a LED driver in LED
lighting.
Internal and external drivers
Drivers can be either internal or external. External
drivers are generally used in tape lights, downlights, cove lights etc. The
advantage of external drivers is the extension of the life of the LEDs. Drivers
may fail before the actual completion of expected lifespan of LEDs because of
factors such as higher temperatures in operating environments. A simple
replacement of the external drivers will give the LED extra life, without
having to replace the LED itself.
Power factor correction to ensure
longevity of installation with better illumination
LED
drivers offer power factor correction to ensure that the LEDs are supplied
with corrected power wattage which optimises the output and gives longevity to
the LEDs. LEDs are designed to function without problems for more than 20000
hours. This is primarily because of the smooth conversion of high voltage
alternating current to low voltage direct current to the desired input wattage
of the LEDs. This conversion is critical both to the operation and the lifespan
of the product.
Constant voltage drivers for
steady supply of wattage
Through the use of resistors, drivers achieve a steady
output of 12V DC. This steady wattage drives the LEDs to offer the right lumens
at the right operating temperature. One of the important and unique features of
LED is the fact that heat is dissipated through sinks to prevent overheating of
the LEDs. The combination of the right wattage and the dissipation of heat actually
lend a long life to the LEDs.
