There are a large variety of constant current LED driver circuits that we carry to meet the needs of our customers. LED technology, especially in computer applications, relies on constant current LED driver circuits heavily. Since LED technology is energy efficient, cost-effective and actually effective, it's usually a go-to mode of providing current in most LED applications. A lighting source which lasts thousands of hours is going to need a power source which can meet such a high demand. As a result, LEDs very often require a constant current LED driver circuit, and there are good reasons. A system of constant current has the ability to vary voltage as it is stratified across a given circuit. This allows a regular, constant electric current to be continuously maintained. The driver circuit in the case of LED applications usually functions as a kind of current regulator. Even though a high series resistance is more than sufficient to light an LED, things like high current run the risk of burning an LED out. Not all LED driver applications require such measures, but ones that are secure and reliable definitely do. ...Read More
