Germicidal lamp is actually belongs to a kind of low pressure mercury lamp.
Low pressure mercury lamp is to use low mercury vapor pressure (
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.
Displays in the following several aspects: 1, the transmittance is different, 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 light intensity attenuation, it is easy to hundreds of hours after its ultraviolet intensity is it light have fallen sharply, to 50% of the initial -
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.
Ultraviolet disinfection sterilization USES is very wide, hospitals, schools, nurseries, cinemas, buses, office, family, etc. , it can purify air, eliminate mildew, time also can produce a certain amount of negative oxygen ions, the ultraviolet disinfection room, particularly pure and fresh air.
In public, the ultraviolet disinfection, can avoid some germs spread by air or by surface.
Long life of ultraviolet germicidal lamp in the water disinfection, environmental protection engineering application is of great significance, water disinfection equipment such as pure water system, generally within 24 hours, ultraviolet germicidal lamp life and high reliability is required, if the lamp life is short, high cost of replacement bulbs, and it is not convenient.
Tepro (China) Co., Ltd. outfits our businesses with ultraviolet light water purifier because they're relatively affordable and highly customizable.
What are you waiting for? Don't you want to provide perfect support to uv disinfection lamp? If yes, so, switch to submersible uv light right away!
uv sterilization lamp uv disinfection lamp is slower than uv disinfection lamp but has a number of special applications, such as for uv sterilization lamp.
Though the cost of these sustainability initiatives as germicidal lamp can be high, harnessing the power of an ethical supply chain to appeal to conscientious consumers can be a smart move both ethically and financially.
