What is an LED?_ An LED (Light Emitting Diode) is a type of semiconductor device that converts electrical energy into light. _How does it work?— When a voltage is applied to the LED, electrons recombine with holes, releasing energy in the form of photons, which we see as light. _Key Characteristics:_ ���_Color_: LEDs are available in a range of colors, including red, orange, yellow, green, blue, and white. ��_Brightness_: Measured in lumens (Im) or candelas ���_Voltage_: Typically operate betwee
