3mm yellow LED, also known as a 3mm yellow light-emitting diode, is a tiny, high-efficiency light source with a diameter of 3mm. It is widely used in various fields due to its excellent performance and stable quality. This article will introduce the industry of 3mm yellow LED, covering its basic principles, applications, market trends, and future development prospects.

Basic Principles of 3mm Yellow LED

The 3mm yellow LED is a semiconductor device that emits light when electricity passes through it. It is made of a semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP), with a yellow phosphor coating on the surface. When an electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of light. The yellow phosphor coating enhances the light output and stabilizes the light color.
