Description
Technical field
The utility model relates to a kind of plane fluorescent lamp, be used for illumination, liquid crystal display back illumination, desk lamp, ornament lamp, auto lamp, street lamp, enclosure wall ceiling light, Solar lamp and information demonstration etc., alternative existing tengsten lamp, fluorescent lamp, hot cathode and cold cathode energy-saving lamp etc.
Background technology
Fluorescent lamp has hot cathode and cold cathode two classes, the former luminous efficiency height, luminous flux height, but the life-span is shorter, and caliber is big, be difficult to make flat-type flourescent lamp (or claiming plane fluorescent lamp); Latter's long service life, brightness height, to save energy, light modulation easily, volume little, can be made into plane fluorescent lamp, has been widely used in the liquid crystal display back illumination at present.
The cold cathode plane fluorescent lamp of prior art mainly contains two classes: the one, and side-light type back light is placed in the side of a LGP as the cathode fluorescent tube of light source, and the cold-cathode fluorescence lamp issued light reflects to form area source through LGP; The 2nd, the direct-viewing type backlight also claims the direct-viewing type plane fluorescent lamp.This two classes cold cathode plane fluorescent lamp is because the whole lamp that luminous efficiency is owed high, also is not made into replaceable existing general lighting lamp at present is mainly used in the liquid crystal display back illumination.
The direct-viewing type cold cathode plane fluorescent lamp of prior art mainly contains three kinds: the one, form a plane fluorescent lamp by a series of straight, cathode fluorescent tubes U-shaped or snakelike and a reflection cavity, and for example GL Philips LCD patent 6,793,370; The 2nd, by the flat-plate light source of two plate glass vacuum seal Cheng Youyi plate cavitys up and down, be filled with discharge gas in the cavity, sparking electrode is placed on the plate glass or two sides of plate cavity; The 3rd, become a flat-plate light source by two blocks of plate glass up and down with a series of dividing plate vacuum seals with snakelike discharge channel, or become a flat-plate light source with a backboard vacuum seal with snakelike discharge channel with snakelike groove by one flat plate glass, sparking electrode is placed in two ends of discharge channel, for example GL Philips LCD patent 6,765,633.The three can be used for the liquid crystal display back illumination, does not all have to constitute a whole lamp with driver, electric connector etc., all can not replace existing general lighting lamp and be used for general lighting.
First kind of main flow that the cold cathode plane fluorescent lamp is the LCD backlight source of present giant-screen wherein, it has brightness height, luminous efficiency compare the latter two height, advantages of simple structure and simple; But its luminous efficiency is compared with conventional fluorescent lamps, then luminous efficiency is low, power consumption is high; Most of electrical power of existing full-color liquid crystal display, for example digital camera, notebook computer, LCD TV etc. is consumed on the backlight, and the luminous efficiency that how further to improve back-illumination source has become the important topic of the full-color liquid crystal display electrical power consumed of further reduction; Simultaneously, owing to its luminous efficiency is owed high, can't be used for general lighting.On the other hand, this class plane fluorescent lamp is very high for the coherence request that obtains uniform luminosity, each cold-cathode fluorescence lamp, and the quite thick reflection cavity of needs to be obtaining uniform face brightness, thereby the thickness of this class plane fluorescent lamp is big, volume is big; In addition, when light source is very big, when cathode fluorescent tube is very long, the fluorescent tube easy fracture, bad mechanical strength is when particularly making light source with snakelike cathode fluorescent tube, because of fluorescent tube length length, bad mechanical strength, fracture easily, the fluorescent tube spacing is big simultaneously, operating temperature is low, and luminous efficiency is low.Therefore, this kind cold cathode plane fluorescent lamp can only be used for the liquid crystal display back illumination at present, fails to make high efficiency, the high-power dull and stereotyped cold-cathode fluorescence lamp that can be used for general lighting.
The profile of above-mentioned second and third kind cold cathode plane fluorescent lamp be plate shaped, thickness is less, but luminous efficiency is all very low, and is particularly second kind, very little because of the passage length of gas discharge, luminous efficiency is all very low.A large amount of heats of discharge generation are difficult to dissipate though the third has the passage of long gas discharge, when high brightness, high-power operation, can Yin Wendu too high and make luminous efficiency very low.In addition, this manufacturing process of two kinds is all very complicated, need be with low-melting glass sealing-in at high temperature, and this high temperature can damage luminescent powder, cause the decline of luminous efficiency; Between the adjacency channel of the third snakelike discharge channel easily because of the defective short circuit of frit seal, whole lamp was lost efficacy.
In a word, the plane fluorescent lamp of prior art can't be used for general lighting.
