Bacterial diaper rash may be caused by several different organisms. The most common are Staphylococcus aureus (Staph), which also causes impetigo, and Group AStreptococcus (Strep), which usually is seen as strep throat.
A light-emitting diode (LED) is a semiconductor device that creates light using solid-state electronics. A diode is composed of a layer of electron rich material separated by a layer of electron deficient material which forms a junction.
Here's a breakdown of how a typical modern LED works: 1  Before any light is emitted, electricity must first pass through an LED driver. 2  The diode, which is the most simple type of semiconductor, glows when electricity passes through it. 3  Picture that warm, inviting, uniform glow of a traditional table lamp.
