LED (Light Emitting Diode)

LED stands for "Light Emitting Diode" and refers to a semiconductor device that emits light when an electric current passes through it. The primary material used in LEDs is silicon. The most crucial component of an LED is the LED chip, which is made of semiconductor material and emits light. This chip is a point light source, and light is directed in a specific direction through a reflective element embedded in the casing. The resistance of LEDs is dynamic, meaning it changes according to the current passing through it. Therefore, if an LED is directly connected to a current source, it can cause a short circuit. To prevent this, a series resistor must be added to the circuit. Similar to a Zener diode, LEDs maintain a constant voltage drop.

Reasons for Choosing LEDs
