In this article, we will delve into the intricacies of the 4mm Multi-Color LED Diode industry, exploring its technology, applications, market trends, and future prospects.

Technology Behind 4mm Multi-Color LED Diodes

4mm Multi-Color LED Diodes are based on the principles of semiconductor physics. They consist of a tiny semiconductor chip, typically made of gallium nitride (GaN), sapphire, or silicon carbide (SiC), which emits light when an electric current passes through it. The color of the light emitted depends on the chemical composition of the semiconductor material.

To produce multi-color LEDs, manufacturers incorporate different semiconductor materials that emit light at specific wavelengths. For instance, red LEDs are typically made from aluminum gallium indium phosphide (AlGaInP), green LEDs from gallium nitride (GaN), and blue LEDs from zinc selenide (ZnSe) or gallium nitride (GaN). By combining these materials, manufacturers can create diodes that emit a wide range of colors.
