Fluorescent Lamp Gas at Celia Morgan blog

Fluorescent Lamp Gas. How the fluorescent lamp works. All fluorescent lamps are essentially high vacuum lamps, filled to a very low pressure with one or more inert gases. A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour. The tube contains a small bit of mercury and an inert gas, typically argon, kept under. When powered on, a voltage surge ionizes the gas mixture in the tube, causing mercury atoms to emit ultraviolet light, which excites the phosphor coating to produce. Fluorescent lamps are more efficient than incandescent lamps, with a luminous efficacy of 50 to 100 lumens per watt. The gas performs several key. We discuss two types of fluorescent lamps: When current flows through the gas between the electrodes, the gas is ionized and emits ultraviolet radiation. The central element in a fluorescent lamp is a sealed glass tube. Simple explanation hot and cold cathode lamps: Metal electrodes at each end are coated with an alkaline earth oxide that gives off electrons easily. Working principle of fluorescent lamp:
