5mm blue LED, also known as a 5mm blue light-emitting diode, is a widely used and highly efficient light source in various industries. As a key component of LED technology, it plays a crucial role in lighting, display, and other applications. This article will provide an in-depth introduction to the 5mm blue LED, covering its characteristics, applications, and market trends.

Introduction to 5mm Blue LED

The 5mm blue LED is a semiconductor device that emits blue light when an electric current passes through it. It consists of a gallium nitride (GaN) crystal as the active layer, with a sapphire or silicon carbide (SiC) substrate. The GaN crystal is doped with indium (In) and gallium (Ga) to create a p-n junction, which emits blue light when forward-biased. The 5mm blue LED has several advantages over traditional lighting sources. Firstly, it has a high luminous efficiency, which means it can produce more light with less power consumption. Secondly, it has a long lifespan, typically 20,000 to 50,000 hours, which reduces maintenance costs. Finally, it is environmentally friendly, as it does not contain mercury or other harmful substances.
