Mercury lamp is an electric light source that uses mercury vapor generated during mercury discharge to obtain visible light. Mercury lamps can be divided into three types: low-pressure mercury lamps, high-pressure mercury lamps, and ultra-high-pressure mercury lamps. When a low-pressure mercury lamp is ignited, the vapor pressure of mercury is less than one atmospheric pressure, and the main radiation wavelength of mercury atoms is ultraviolet light at 253.7nm. The commonly used "fluorescent lamp" tubes are coated with halogenated calcium phosphate fluorescent powder on the inner wall, which then converts ultraviolet light into visible light. The inner wall of energy-saving fluorescent lamps is coated with rare earth fluorescent powder, which has higher luminous efficiency
