Description
Technical field
The invention belongs to display and lighting source and make the field, relate to a kind of fluorescent lamp, particularly a kind of plane medium blockage discharge fluorescent lamp that can be used as backlight of LCD and general lighting light source.
Background technology
Along with the continuous reduction of the further maturation and the manufacturing cost of production technology, big screen LCD (LCD) more and more is widely used in recent years.The plate of flat liquid crystal display of big information capacity is generally transmission-type, need dispose light source and realize showing behind liquid crystal board.The backlight that present plate of flat liquid crystal display generally adopts is cathode fluorescent tube (CCFL), its advantage is light efficiency and brightness height, and its shortcoming is that brightness time that reaches capacity after lighting is long, it is influenced by ambient temperature big and the life-span is shorter to light a fire, for making display brightness evenly also need dispose reflector, light guide plate, parts such as diffuser plate and prism plate, make the luminance loss of fluorescent tube bigger, and because it needs mercury vapour as working gas, the production of CCFL and discarded all can pollute to environment, therefore many new type light sources have been developed at present to replace CCFL, mainly contain electroluminescence (EL) plate, light-emitting diode (LED), Organic Light Emitting Diode (OLED) plate and plane medium blockage discharge fluorescent lamp (hereinafter to be referred as flat florescent lamp) etc., wherein flat florescent lamp is owing to can realize the large tracts of land uniformly light-emitting, life-span is long, advantage such as pollution-free and enjoy attention.In addition, flat florescent lamp also can be used as the general lighting light source, as ceiling light, pendent lamp and wall lamp etc., has very strong decorative effect.
Flat florescent lamp is pressed the electrode structure difference, mainly can be divided into creeping discharge type and subtend discharge-type two big classes.A kind of structure of typical creeping discharge type flat florescent lamp is at present: be made up of front glass substrate and back glass substrate, the medial surface of front glass substrate disposes phosphor powder layer, the medial surface of back glass substrate disposes electrode, be coated with dielectric layer on the electrode, cover the layer of even reflector on dielectric layer surface and the back glass substrate medial surface that do not covered by dielectric layer, cover phosphor powder layer on the reflector, maintained a certain distance by support column between forward and backward substrate, inside charges into inert gas.Every isolychn comprises three parallel poles, and middle one is negative electrode, and its dual-side is being arranged many kicks with certain spacing, and the dual-side projection position is interlaced, and two strip electrodes of negative electrode both sides are anodes, and luminous plaque adopts unipolar pulse to drive.During work, under suitable potential pulse effect, produce glow discharge between negative electrode projection and corresponding anode, and this micro discharge is launched into triangle from negative electrode projection anode, the ultra-violet radiation excitated fluorescent powder that the triangle region of discharge produces sends white light.The light-emitting area of whole lamp tens even the hundreds of leg-of-mutton luminous zone that distributing equably makes brightness uniformity reach about 85%.The existence of negative electrode kick has reduced the distance between negative electrode and anode on the one hand, has point effect on the other hand, has increased interelectrode field intensity, and helps to prevent that micro discharge is shrunk to a fine electric arc (being that positive column shrinks).
