A neon lamp is a type of gas discharge lamp that utilizes neon gas to produce light. It works on the principle of electroluminescence where light is produced as an electrical current passes through the neon gas within the lamp. The neon gas glows brightly due to the interaction between the electrons in the gas and the electric current, producing a distinctive red-orange color. Neon lamps’ vibrant colors and high visibility have made them popular in advertising and signage. They are often used in neon signs, decorative lighting, and various types of electronic equipment.
