Mercury lamp Mercury lamp uses the mercury vapor to generate mercury vapor 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 the low-pressure mercury lamp is ignited, the mercury vapor pressure is less than one atmosphere, and the mercury atom mainly emits ultraviolet light having a wavelength of 253.7 nm. The commonly used "fluorescent lamp" tube is coated with a calcium halophosphate phosphor, which converts the ultraviolet light into visible light. The inner wall of the energy-saving fluorescent lamp is coated with rare earth phosphor, and the luminous efficiency is higher.
