Ultraviolet ray sterilization lamp need not need to add lamp shade
Ultraviolet radiation sterilization principle is the use of appropriate wavelength of ultraviolet light to destroy microbial DNA (deoxyribonucleic acid) in the body's cells or RNA (ribonucleic acid), the molecular structure of the growing cell death and (or) regenerative cell death, to achieve the effect of sterilization. And because of short wave ultraviolet ray can't pass ordinary glass, so general ultraviolet ray sterilization lamp does not need to add lampshade.
Ultraviolet germicidal lamp is actually belongs to a kind of low pressure mercury lamp, low-pressure mercury lamp is to use low mercury vapor pressure (< 10-2 pa) was intensified and emit ultraviolet light, its hair spectral line mainly is 253.7 nm wavelength and two 185 - nm wavelength, the two are invisible to the naked eye of ultraviolet light. Ultraviolet germicidal lamp tube is made of quartz glass tubes after mercury lamp according to light up the mercury vapor pressure difference and ultraviolet light output intensity is different, divided into low pressure mercury lamp, medium voltage, low strength high strength mercury lamp and low pressure mercury lamp three kinds of high strength. Because ultraviolet light can penetrate the cell death, because this should pay attention to when using a ultraviolet disinfection can't direct illuminate to a person's skin, especially people's eyes, don't look straight tubes, ultraviolet germicidal lamp light because shortwave ultraviolet not through ordinary glass, wearing glasses can avoid injury to the eye. If it is not a minor injury, the general situation is nothing serious, just like being burned by the sun, severe eye drops or human milk can help the recovery. In the case of someone, don't use an ozone lamp, which can be toxic when the ozone concentration is high.
Ultraviolet ray sterilization lamp does not need to use lampshade. The use of sterilization lamp USES similar fluorescent lamp, different is to choose to be a specialized ballast, stand and fluorescent lamp can be general. If the customer must use lamp shade, it does not matter, as long as the light irradiation to sterilize surface, and can produce some ozone, reach the corner where no irradiation sterilization effect.
