Technology of 5mm Round LED

The technology behind the 5mm round LED involves the use of a semiconductor material that emits light when an electric current is applied. The most common semiconductor materials used in 5mm round LED are gallium nitride (GaN), gallium arsenide (GaAs), and silicon carbide (SiC). These materials emit light in different colors depending on their composition and structure. The 5mm round LED consists of a small, round semiconductor chip encapsulated in a transparent or colored plastic lens. The lens helps to focus the light and protect the semiconductor chip. The size of the 5mm round LED is determined by the diameter of the plastic lens, which is typically 5mm. The efficiency of a 5mm round LED is measured by its luminous efficiency, which is the ratio of the light output to the electrical power input. High luminous efficiency means that the LED can produce more light with less power, making it more energy-efficient.
