Rare gases, such as xenon and krypton, are widely used in lighting manufacturing. They are utilized in specialized lamps, such as xenon arc lamps and krypton discharge lamps, due to their unique properties. These gases emit bright and intense light when an electric current is passed through them. Xenon is commonly used in applications that require high-intensity illumination, such as automotive headlights and movie projectors. Krypton is often used in fluorescent lamps and other lighting fixtures due to its ability to produce a steady and efficient light output. These rare gases play a crucial role in achieving optimal lighting performance and energy efficiency in various lighting applications.
