Light Emitting Diodes - Engineering LibreTexts
WebMay 1, 2008 · An LED’s plastic body is not thermally conductive, and the device does not radiate heat. The only effective cooling method is to remove heat through the device bottom. Therefore highly thermally-conductive materials are commonly used to take the heat from the LED’s back side (see Fig. 1 ). WebWorking of an LED In terms of electronics, LED is defined as a p-n junction diode with an energy gap in the range required for visible light production. The semiconductor consists of a p junction, n-junction and a neutral region between them. WebThe “Light Emitting Diode” or LED as it is more commonly called, is basically just a specialised type of diode as they have very similar electrical characteristics to a PN … fox news 8 new orleans live
