lLed
lLed, also known as Light Emitting Diode, is a semiconductor device that emits light when an electric current passes through it. Discovered in the early 20th century, the first practical LEDs were developed in the 1960s. Early LEDs produced low-intensity red light, but advancements in materials science have led to the development of LEDs that emit a wide spectrum of visible light, as well as ultraviolet and infrared light.
LEDs work based on the principle of electroluminescence. When a voltage is applied across the semiconductor
The advantages of LEDs over traditional lighting technologies like incandescent and fluorescent bulbs include their long
LEDs are used in a vast array of applications. They are common in indicator lights, digital displays,
