Introduction to 5 mm Red LEDs

The 5 mm red LED, also known as a 5 mm red light-emitting diode, is a small, round semiconductor device that emits red light when an electric current passes through it. These LEDs are widely used in various applications, from indicator lights and displays to decorative lighting and automotive industry. With a diameter of just 5 mm, these LEDs are compact and highly efficient, making them a popular choice for a wide range of applications.

How 5 mm Red LEDs Work

To understand the working principle of a 5 mm red LED, it is essential to know about the basic structure of an LED. An LED consists of a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium indium phosphide (AlGaInP). When an electric current is applied to the LED, the electrons and holes within the semiconductor recombine, releasing energy in the form of photons. In the case of a 5 mm red LED, these photons are red in color. The color of the light emitted by an LED is determined by the energy band gap of the semiconductor material. A smaller energy band gap results in a higher frequency of light, which corresponds to a shorter wavelength. In the case of a 5 mm red LED, the energy band gap is around 1.8 eV, resulting in a red light with a wavelength of approximately 620-640 nm.
