3mm yellow LED, also known as a 3mm yellow light-emitting diode, is a compact and highly efficient light source that has found widespread applications across various industries. These LEDs are renowned for their small size, bright yellow output, and long lifespan, making them a popular choice for lighting, signaling, and decorative purposes.
Introduction to 3mm Yellow LED Technology
3mm yellow LEDs are a type of semiconductor device that emits light when an electric current passes through it. The technology behind these LEDs has evolved significantly over the years, leading to improved efficiency, color consistency, and longevity. The 3mm size refers to the diameter of the LED's housing, which is a standard size for many applications.
These LEDs are typically made using gallium nitride (GaN) or gallium phosphide (GaP) as the semiconductor material. The yellow color is achieved by doping the semiconductor with certain impurities that absorb blue light and re-emit it as yellow light. This process is known as phosphorescence.
