------Ultraviolet radiation is a kind of invisible light and Ultraviolet light frequencies are above violet on the spectrum, whose wavelength range is from 136nm to 400nm, divided into three wave bands: A,B,C and vacuum ultraviolet radiation. Their most effective germicidal wavelength(C wave band) is between 180nm- 275nm, especially 253.7nm, which is called germicidal UV light. They can impactfully eliminate bacteria, epiphyte, virus, alga in the air and water and the other microorganism, even the recycled ability. UV technology is a non-chemical approach to disinfect, and this method of disinfection is simple, high-efficiency
and very low cost of maintenance.

------Cnlight UV germicidal lamps use the cold cathode ultraviolet tube, namely, CCFL UV lamps, made of excellent material and particular glass, have intensive germicidal effect and long service life, and the average life of the lamp is more than 9,000 hours. The ultraviolet ray of 253.7nms which send out by the tube can be easily absorbed by the protein and nucleic acid of germs and virus. It will destruct the DNA structure of the protein and nucleic acid and cause the germs and virus dead. Activate oxygen to form the second most powerful sterilant in the world, ozone, which kills germs by rupturing their cell wall and attacking their nucleus. UV Lamp works will be with UV-reactive or phosphorescent surfaces . The professional filament esigning and special electron coating make the lamp starts easily and performs well with tens of thousands of switch. You can get the ideal germicidal effect in 1-2seconds. Otherwise, it can protect the environment and has no secondary pollution.

UV lamp working principles:

------Ultraviolet lamps produce 254nm & 185nm UV rays due to low pressure mercury vapor, as fluorescent lamps and energy lamps do. The glass of fluorescent and energy saving lamps is regular, which can’t radiate outside, but absorbable to phosphor then change to visual. Ultraviolet lamps use quartz glass or special glass that UV rays radiate from.

------Principles and characteristics of sterilizing:

------254nm UV ray is readily absorbable to cell(see table 1), destroy genome DNA and kill bacteria, so called “Bacteria lamps”.
Kill bacteria and virus in a very short time, please see chart 1. Physical disinfection, no second time pollution.
