Light Emitting Diode (LED)
Definition - What does Light Emitting Diode (LED) mean?
A light emitting diode (LED) is a two-led semiconductor diode that emits light when a voltage is applied through it. It resembles a basic p-n junction diode, but also emits light. LEDs are used in lighting devices including emergency lights and safety indicators. LEDs are also used in systems like electronic devices, electronic displays, billboards, location direction and instructional signage, watches, calculators, mobile phones, televisions, monitors of computers, laptops, gaming consoles and personal digital assistants, etc..
Safeopedia explains Light Emitting Diode (LED)
The first visible LED was invented in 1962. Since then, LEDs are undergoing revolutionary changes in terms of technological development, which has resulted in low electricity consumptions and varieties of uses. New versions of LEDs include organic LEDs (OLED), active-matrix organic LED (AMOLED) and polymer LEDs (PLED). These new types of LEDs have improved cost per lumen and output per device. LEDs are becoming more popular as these are thinner and brighter than LCDs. These are also light weight, energy efficient and provide better angular views than LCDs and, therefore, are quickly replacing LCD monitors.
