The CCFL (Cold Cathode Fluorescent Lamp) is a light source classified as an electronic component. The CCFL in simplest terms is a gas-discharge light source, which produces its output from a stimulated phosphor coating inside the glass lamp envelope. A CCFL can be described as a transducer converting electrical energy into light energy.
Cold cathode fluorescent lamp is the fluorescent lamp which is operated in the range of normal glow discharge. Rare gas and a slight amount of mercury (a few mg) are filled in the glass tube coated with phosphor(fluorescent materials). By adding high electric field between electrodes at both ends of the glass tube, glow discharge occurs in the low pressure mercury vapor. Mercury atoms which are excited by its discharge, emit ultraviolet rays. (253.7Nm), and these ultraviolet rays excite the phosphor. rig
Features

Applications
Light sources for Scanner.
Various types of displays and decorating lights.
Backlighting for LCD.
LCD backlight serve as the illumination source for LCD. LCD backlight frequently employ fluorescent lamps. Fluorescent lamp consists of a phosphor coated glass cylinder with cathodes at each end.
Carry light source to offer LCD light source of panel. Mainly by light source, lead all board, optics made up of diaphragm, plastic frame,etc.. Carry light source have luminance to be high, longe-lived giving out light characteristic such as being even. Have EL, CCFL, LED three carry light source type mainly at present , distribute position with divide into and incline person who carry and go to type direct in accordance with light source.
To brighter, more light constantly, thin direction develop with LCD mould group, incline person who carry CCFL type carry light source become at present carrying light source mainstream of development. As regards range of application, EL, used in light size, monochromatic light( getting green, red) mainly by LED. Have white light( panchromatic) EL and LCD carry light source come out successively too recently. But because luminance use than dark their for 4 following little size liquid crystal show basically.
For instance: Cell-phone, PDA, game machine,etc.. Getting panchromatic, large size luminance carry light source, mainstream to make the light source with CCFL still now, And riper through the development technological craft for many years, the trusting is high, Performance is steady. TFT LCDs generally use CCFL for the large-and-middle-scale size( 19-3 inches) now. There are itses concrete product for civilian use: Liquid crystal TV( 20" - 30"); Liquid crystal computer display( 14" - 10"); Portable computer display( 8" - 14"); Portable DVD player( 5"- 9); Automobile, train,, plane TV, GPS show ( 3" - 5") year; Lottery game machine( 3" - 5"); Portable TV( 3" - 5"); Children person who study, palmtop computer, game machine( 3" - 5"); Instrument, industry of OA, show ( 5" - 10"); Videophone( 5" - 10")

ULTRA VIOLET
| The UV lamp is truly Ultra Violet -- a black light. Like any black light, it doesn't emit much visible light. However, it does emit a lot of ultra violet light that you cannot directly see. What little light you do see directly is a very deep purple. UV works best with UV-reactive or phosphorescent surfaces. And, of course, with any day-glo surface as well.
It is a new generation Illuuminating source focus on paper money testing machine. The ultraviolet wavelengh of the tube is 365nm +- 5nm. Now, we can product the length by dia.3.0 ~ dia.8.0 and different shape cold cathode ultraviolet fluorescent lamps.

Ultraviolet radiation is a kind of invisible light whose wavelength range is from 136nm to 400nm.It is divided into three wave bands:A?B?C and vacuum ultraviolet radiation.
A wave band: 320nm-400nm
B wave band: 275nm-320nm
C wave band: 200nm-275nm
Vacuum wave band: 100nm-200nm
Ultraviolet radiation has the most bactericidal efficacy in 240nm-280nm wave band, especially in 253.7nm.Its bactericidal principle is: Because the cell absorb wave light farthest in 250nm-270nm, in fact absorbed ultraviolet radiation has effect on DNA, which gets up a actinism. The energy of ultraviolet radiation is absorbed by alkali group in DNA to change and destroy microbial framework (DNA-ribotide), then lead to ribotide framework broken and the end of the organism or losing the function of copy. Once the function is broken, sterilization or antisepsis is achieved.
Now ultraviolet radiation has been widely used in drinking water.pure water.electron.medical treatment.atmosphere cleanse antisepsis and sewage disposal in protecting environment and so on, it is one of the optimal manners of decontaminating water accepted in the world.
Characteristic:
1. Widely application.fast seed.high efficiency and good impact
2. Easy to use, small volume, portability, saving-power and high life.
