High pressure mercury lamp working principle
2023-05-31 11:14:15
When the high-pressure mercury lamp is in operation, the current passes through the high-pressure mercury vapor to cause ionization excitation to form a collision between electrons, atoms and ions in the discharge tube to emit light. The resonance line (extraradiation spectrum) with a wavelength of 253.7 nm during absorption is absorbed, and the intensity of the line is increased. The main radiation is visible lines of 404.7 nm, 435.8 nm, 546.1 nm, and 577.0 to 579.0 nm, and the radiation is strong. Long-wave ultraviolet light of 365.0 nm.
