Description

Flat type discharge lamp
Technical field
The present invention relates to flat type discharge lamp.
Background technology
In the past, as the flat type discharge lamp that the backlight of for example LCDs uses, known had a described flat type discharge lamp of No. 3026416 communique of patent (patent documentation 1).This flat type discharge lamp is characterised in that, it is by the panel that becomes light-emitting area with light transmission, the electrode that the nesa coating that forms on the inner surface by this panel constitutes, cover this nesa coating as beyond the part of outer electrode and the dielectric layer that is provided with light transmission, insulated substrate with the configuration of panel subtend, and overlayed on formations such as fluorophor on this insulated substrate, front substrate and insulated substrate sealing-in are integral, inside charges into rare gas and mercury, and the section configuration that is arranged on the discharge loop on the insulated substrate is made towards unlimited such inclination or the curved surface of panel, the perhaps shape that they are combined.At this moment, the relative discharge loop orthogonal configuration of electrode.
In the past, as flat type discharge lamp, known also had the spy to open the described flat type discharge lamp of flat 10-222083 communique (patent documentation 2).The electrode of this flat type discharge lamp is identical with above-mentioned existing example along the basic comprising that the vertical direction with respect to spacing body disposes, but electrode is arranged on the outer wall of front substrate.
Have, as another existing example, known also have the spy to open the described flat type discharge lamp of 2003-217517 communique (patent documentation 3) again.This existing flat type discharge lamp and above-mentioned the 1st, the 2nd existing example similarly have following formation, be about to the 1st with the 2nd electrode along vertical direction configuration with respect to a plurality of thin leptophragmata wall that these the 1st electrodes is become a plurality of discharge spaces with the 2nd electric discharge between electrodes space segmentation.In addition, in the 3rd existing example, the 1st electrode and the 2nd electrode are made of one, can improve the charge concentration degree and to improve discharging efficiency, and have opposite one another the 1st protuberance and the 2nd protuberance, make and protrude to the inner space from above-mentioned the 1st electrode and the 2nd electrode.
But, in these existing flat type discharge lamps, when the inner space being divided into a plurality of discharge spaces in the next door that utilizes wire and pair of electrodes being disposed at the two ends of each discharge space, can produce such as Figure 16, problem shown in Figure 17.State when Figure 16 indication lamp extinguishes, the state when Figure 17 indication lamp is luminous.Figure 16 is the profile of the lamp of relative position relation between expression spacing body 5 and electrode 6a, 6b, and electrode 6a, 6b are configured in the outer wall of lamp, or adopts the structure that covers with dielectric layer again after being coated on the lamp inwall.For the ease of to lamp bank gas or inflation, next door 5 is configured to its two ends and does not contact sidewall 3, forms the structure that each discharge space links to each other.Therefore, as shown in figure 17, when adding alternating voltage between electrode 6a, 6b, for example only form discharge loop at the space A that indicates oblique line, Blank Space B does not form discharge loop, so only produce in the luminous problem of space A part.
No. 3026416 communique of patent documentation 1 patent
Patent documentation 2 spies open flat 10 1 No. 222083 communiques
Patent documentation 3 spies open the 2003-217517 communique
Present inventors find the following fact after the existing flat type discharge lamp shown in Figure 17 is understood fully the reason of having only the discharge space that discharge in the partial discharge space, generation is not discharged.As shown in figure 17, when voltage was added in outer electrode 6a, the 6b that is configured in a plurality of discharge spaces two ends, electric field action was in all discharge spaces.But each discharge space causes the lamp starting voltage slightly different because of the surface state of contact glass of outer electrode or fluorophor or the difference of electrode state, early start discharge in the low discharge space of starting voltage.Here, the glass part of the formation discharge vessel that contacts with outer electrode, the glass part that perhaps covers the internal electrode surface plays the effect as the dielectric barrier of capacitor, before forming discharge loop, with the polarity charging identical with applied voltage, but, just become the polarity opposite with applied voltage in case form discharge loop.Now, in the discharge space A of Figure 17, produce electric discharge phenomena the earliest, then because discharge makes the voltage at dielectric barrier two ends become the polarity opposite with applied voltage as supposition.
At this moment, owing to the adjacent discharge space B of discharge space A does not discharge, so this dielectric barrier is with the polarity charging identical with applied voltage.This electric charge is because the current potential of the dielectric barrier of adjacent discharge space A is lower than discharge space B, and is therefore through the discharge space A discharge of this dielectric barrier to discharge earlier, inoperative to the discharge of discharge space B.Thereby final result makes discharge space B keep the state that does not discharge.
In addition, this phenomenon is not almost found in the flat florescent lamp of more small-sized and discharge space length weak point.Although its reason is to have some error on discharge space, because the voltage that is added on outer electrode 6a, the 6b is enough high, so in all discharge spaces, produce discharge.But in the large-scale flat type discharge lamp of the present invention,,, as mentioned above, understood the reason that above-mentioned phenomenon takes place so discharge ionization voltage also raises because discharge space is elongated as object.
The present invention proposes for solving the above-mentioned technical problem of newly making clear, and its purpose is to provide a kind of large-scale plane discharge lamp that can be luminous in all discharge spaces through cutting apart.
