low-pressure discharges

Low-pressure discharges refer to the electrical discharges that occur in gases at reduced pressure levels, typically in a vacuum or low-density environment. When a voltage is applied, the gas molecules become ionized, allowing electricity to flow and producing light, often seen in neon signs or fluorescent lamps. This process generates visible light without the need for high energy, making it efficient for lighting applications. Low-pressure discharges are utilized in various technologies, including lighting and plasma displays, due to their ability to create colorful and effective illumination.
