Introduction to 5mm Purple LED
What is a 5mm Purple LED?
The 5mm purple LED, also known as a surface-mount device (SMD) LED, is a compact and efficient light-emitting diode that emits purple light. As one of the smallest LED packages available in the market, it is widely used in various applications, including indicator lights, displays, and decorative lighting. With a diameter of only 5mm, these LEDs are perfect for space-constrained designs and can be mounted on printed circuit boards (PCBs) with ease.
How Does a 5mm Purple LED Work?
A 5mm purple 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 purple LEDs is a combination of gallium nitride (GaN), aluminum nitride (AlN), and silicon carbide (SiC), which together produce a purple glow when an electric current is applied. The LED's color is determined by the energy bandgap of the semiconductor material, with purple having a higher energy bandgap than red or green.
