In this article, we will delve into the details of the 5mm blue LED, exploring its features, applications, and the impact it has had on the industry.

Introduction to 5mm Blue LED

The 5mm blue LED, as the name suggests, is a type of light-emitting diode (LED) that emits light at a wavelength of approximately 470 to 495 nanometers. It is a miniature LED package with a diameter of 5 millimeters, making it suitable for various compact lighting applications. The blue LED is often used as a base color in color mixing, where it combines with red and green LEDs to produce a wide spectrum of colors, including white light.

How 5mm Blue LED Works

The 5mm blue LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in blue LEDs is typically a combination of gallium nitride (GaN), indium gallium nitride (InGaN), and aluminum gallium nitride (AlGaN). When an electric current is applied, the electrons and holes recombine within the semiconductor, releasing energy in the form of photons, which are then emitted as light.
