Technology of 5mm Round LEDs

The technology behind 5mm round LEDs involves the process of semiconductor fabrication. The process begins with the creation of a semiconductor wafer, typically made of silicon or gallium arsenide. The wafer is then etched and doped to create a p-n junction, which is the heart of the LED.

Once the p-n junction is formed, the wafer is diced into individual chips, which are then mounted onto a substrate. The chips are then coated with a phosphor layer, which converts the LED’s electrical energy into visible light. Finally, the LEDs are encapsulated in a transparent or colored plastic package to protect them from environmental factors.

The key factors that determine the performance of 5mm round LEDs include the semiconductor material, chip size, and phosphor type. Different materials and combinations of these factors can result in LEDs with varying brightness, color, and lifespan.
