CHAPTER 6
Light-Emitting Diodes
In this chapter we will explore light-emitting diodes (LEDs) of different emitted wavelengths (e.g., red, green, and blue), and how their “turn-on” voltages (VF) are related. We will also discuss common problems that can cause an LED to fail, such as over current or “excessive” reverse voltage.
The LED’s Light Output
Light-emitting diodes are measured for luminous intensity (light output) in milli-candelas (mcd) at a particular LED current. There are various descriptions of LEDs such as “high efficiency,” “high intensity,” or “high performance.” However, the most important specification to look for is the light ...
