Ultraviolet germicidal lamp theoretical basis
by：LiangYueLiang
2020-09-19
Light is actually belongs to a kind of low pressure mercury lamp.
Low pressure mercury lamp is to use low mercury vapor pressure (
<
10 -
2Pa)
Be intensified and emit ultraviolet light, its hair spectral line mainly have two: one is 253.
7 nm wavelength;
Another is 185 nm wavelength, and the two are invisible to the naked eye of ultraviolet light.
- - - - Used for lighting fluorescent lamp, energy-saving lamps, also belong to the low pressure mercury lamp, rely on the low pressure mercury vapor emission ultraviolet ray, after being inspired with 254 nm wavelength of ultraviolet irradiation on the phosphor to emit visible light, if change the composition and proportion of phosphor, it can we usually see different colors of light.
- - - - Germicidal lamp don't need to be converted to visible light, 253. 7 nm wavelength can have very good sterilization effect, this is because the cells of light absorption lines there is a rule, has the biggest in 250 ~ 270 nm uv absorption, absorbed the ultraviolet ray in fact role in cellular genetic material or DNA, it plays a allochromatic, ultraviolet photons energy absorbed by the base pairs of DNA, cause mutation genetic material, make the bacteria died instantly or cannot reproduce, achieve the purpose of sterilization.
- - - - Fluorescent lamp and energy-saving lamps use common glass, 253. 7 nm ultraviolet through not to come out, can't used for sterilization lamp, quartz glass for uv transmittance is high, up to 90%, is the best material to do the sterilization lamp, but the performance of the quartz glass and common glass there's a big difference in performance ( Mainly different thermal-expansion coefficient) , seal can't use ordinary high degree of automation of the circular sealing way, which makes the germicidal lamp manufacturing technology content than ordinary energy-saving lamps.
- - - - There is a kind of transparent glass, uv known as high boron glass, it is quartz glass for uv transmittance about 60% of its production technology and energy-saving lamps, make its cost and price is far beyond the sterilization lamp, quartz glass production a few tubes of just a few dollars, but it is far less than quartz germicidal lamp on performance. In the following aspects:
- - - - 1, the transmittance is different, in the same test specifications by the same ballast, quartz glass sterilization lamp uv intensity is high boron glass sterilization lamp 1. More than 5 times;
- - - - 2, high boron glass lamp uv germicidal lamp intensity attenuation, it is easy to hundreds of hours after its ultraviolet intensity is it light have fallen sharply, to 50% of the initial - 70%. In the user's hands, although saw tubes or bright, but it may have no effect. And quartz glass light attenuation degree is much less than the high boron lamp, if the production process, 2000 - quartz lamp light attenuation in the light 3000 hours, the light attenuation to the initial 80% After 70%, not as long as the lights, light failure rate will be more and more small.
- - - - Germicidal lamp in China may understand Philip germicidal lamp, Philip has a germicidal lamp is in a close to the common glass glass production, rather than the quartz glass manufacturing, its light transmittance is close to quartz glass transmittance, than China's high boron glass lamp is much higher, can use a high degree of automation of energy-saving lamps production process, the lamp is mainly rely on their refining this glass technology. Its disadvantage is that does not produce ozone.
- - - - Another feature of quartz germicidal lamp is emits ozone. Because quartz glass for shortwave 185 nm uv transmittance is high also, 185 nm uv can ionizing air to produce ozone, the ozone concentration high adverse to human body, but can use when no one occasion, ozone can sterilization, disinfection, just can make up due to ultraviolet ray propagation along a straight line only, disinfection has the defects of a corner.
- - - - Some occasions there can be no ozone, also can use quartz germicidal lamp, the quartz glass when refining added an element - - Titanium ( Ti) , to make it through the uv cut-off in under 200 nm, and the 254 nm uv through basic no effect, known as the ozone sterilization lamp.
- - - - From the above analysis, do the sterilization lamp with quartz glass is the best choice. At home, medical and health field, already do not recommend the use of high boron germicidal lamp, in the United States, Canada, Japan production ultraviolet ray sterilizing lamp widely using quartz glass.
