LED technology is today preferred by everyone and we all want them to part of our home or office. But, if you haven’t brought LEDs before, then you might not know that there are plenty of different ...

Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...
