LED lighting has become increasingly popular as a result of the high efficiency and longer lifespan of the bulbs. However, to keep LED lights functioning properly, they must have an LED driver providing a quality power supply that meets their demands. A constant current power supply is one way of accomplishing this.

 

WHY USE A CONSTANT CURRENT LED DRIVER FOR YOUR POWER SUPPLY?

The use of a constant current LED driver for your LED lighting power supply makes it possible to precisely deliver current to the light, without any inconsistencies or ripples. Constant current LED drivers are a highly reliable power supply and generally have several different fail safe features in place such as short circuit protection, overheat protection, and over current. In addition, using constant current LED drivers as your power supply allows you to scale your system in a linear fashion with adjustable output. Lastly, for the purposes of lighting, this type of power supply allows you to make use of a dimmer switch by utilizing forward and reverse phase clipping as controls.

CHOOSING A CONSTANT CURRENT LED DRIVER FOR YOUR LIGHTING POWER SUPPLY

There are many different constant current power supply options available. In some cases they are chosen because of size and weight restrictions. Today’s LED drivers come in a variety of different shapes and sizes to fit nearly any space. When choosing your LED driver, you should also be cognizant of the expected temperature range of the case itself, as many power supplies can get up to 90 degrees Celsius under heavy loads.

The use of constant current in LED drivers has led to significant improvement in LED lighting and other systems. By eliminating fluctuations in current, and implementing recovery strategies for short circuits or open loads, you can be sure that your indicators will keep shining when you need them most.
