Ultraviolet germicidal lamp (UV lamp) is actually a low-pressure mercury lamp. Like ordinary fluorescent lamps, it emits ultraviolet rays after being excited by low-pressure mercury vapor (<10-2Pa). The difference is that the lamp tube of the fluorescent lamp is made of ordinary glass, and the 253.7nm ultraviolet rays cannot penetrate, and can only be absorbed by the fluorescent powder on the inner wall of the lamp tube to excite visible light. If you change the composition and proportions of the phosphor, it can emit different colors of light that we usually see. Generally, the lamps of germicidal lamps are made of quartz glass, because quartz glass has a high transmittance of ultraviolet rays in various bands, reaching 80%-90%, which is the best material for germicidal lamps.
Germicidal lamps have several structures such as hot cathode low pressure mercury vapor discharge lamps and cold cathode low pressure mercury vapor discharge lamps, which can be divided into various types according to appearance and power.
Quartz glass is very different from ordinary glass in performance, mainly due to the difference in thermal expansion coefficient, and generally cannot be sealed with aluminum caps.
