What is Overview of Light-Emitting Diodes (LEDs) about?

Light-emitting diodes (LEDs) are semiconductor devices that emit light when electric current passes through them. LEDs were invented in 1962 and initially only emitted low-intensity red light, but modern versions can emit across the visible, ultraviolet, and infrared spectrums at very high brightness. LEDs have advantages over incandescent lights including lower energy use, longer lifetime, smaller size, and greater durability. LEDs are now used widely for indicators, lighting, displays, and optical fiber c
