History of Diode LED 5mm

The diode LED 5mm has its roots in the early days of LED technology. In the late 1960s, Nick Holonyak Jr., an engineer at General Electric, invented the first practical LED. However, it wasn't until the late 1970s that LED technology began to gain traction, with the introduction of the 5mm LED. This compact and efficient LED quickly became popular in various applications, such as indicator lights, electronic displays, and consumer electronics.

Technology of Diode LED 5mm

The diode LED 5mm operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. This process is known as the electroluminescent effect. The 5mm LED is typically made of a gallium arsenide (GaAs) or gallium nitride (GaN) semiconductor material, which emits light when an electric current is applied. The 5mm LED consists of a small, round semiconductor chip, which is mounted on a lead frame. The lead frame serves as the electrical connections between the LED and the external circuit. The LED is then encapsulated in a clear, transparent or colored epoxy lens, which protects the semiconductor chip and focuses the emitted light.
