Summary of the invention
In recent years, the requirement of carrying capacity of environment that reduces this discharge lamp is more strong, and the amount of mercury that is enclosed in the luminous tube is lowered in expectation.In addition, the also power consumption of expectation reduction discharge lamp.
In the past, when amount of mercury was low, the luminous intensity of iron distributes can be very uneven; This point has been documented in the documents 1; But the performance of the ballast through improving ignition device etc. are even the few lamp of amount of mercury also can be obtained lighting a lamp of good Illumination Distribution.
Based on above-mentioned background, the frequent input power that switches of expectation uses, and reduces the amount of mercury of lamp with this, lowers power consumption.
For example, have the light a lamp ignition method of power of a kind of switching, the power when the irradiation workpiece when lighting a lamp is usually lit a lamp, and power is reduced, and when needs shine, improves power again.At this moment, the stand-by time of the actual lamp of lighting a lamp that uses is for for example in 1 minute.
But, for the lamp that has reduced amount of mercury, when carrying out the lighting a lamp of frequent power switched as stated, the problem that illumination obviously reduces at short notice can take place.
To this problem, the inventor studies with keen determination, obtains following discovery.
The luminous tube of the lamp that destruction illumination reduces at short notice; Inner wall section for its fragment; Clean the surface of quartz glass of inwall with aqueous hydrogen fluoride solution after; Likewise be etched to when investigating apart from about the surperficial 10 μ m, contain the metal of enclosing to some extent in the zone till inwall to the certain depth of luminous tube with aqueous hydrogen fluoride solution.
By this point, can think that enclosing metal is driven into the inside to luminous tube, and not only terminate in inwall attached to luminous tube.Phenomenon as implied above can be thought taken place when electric current sharply increases when shining by standby.Inferring it the reasons are as follows.
When low power standby, form near the lower state of halogen density of luminous tube inwall.Therefore, if switch to high-power power when switching, the electron density of electric arc can sharply increase, and iron or bismuth etc. are enclosed the atom of metal can be in electric arc and tyco electronics, sudden towards the luminous tube inwall.
In the prior art, there are a large amount of mercurys, so the effect of mercury performance buffering, suppress to enclose metal and squeeze into to luminous tube.But, because the amount of mercury reduction, so buffering effect is little, inclosure metals such as iron or bismuth are driven into easily.
When surpassing 15 times with the difference power in when irradiation in the time of especially can knowing standby, the amount of squeezing into can sharply increase.
As implied above, when the inclosure metal was driven into to luminous tube inside, the inner luminescent substance of luminous tube can reduce, and illumination can reduce, so the illumination sustainment rate can reduce.
Owing to above reason, the purpose of the utility model is to provide a kind of long arc type discharge lamp, in luminous tube, disposes pair of electrodes relatively, and enclosing has 0.5mg/cm
3Metal and halogens such as following mercury, iron even under the situation that the power that power is risen switches, also can suppress to enclose the phenomenon that metal is driven into the luminous tube inwall, prevent to reduce in the illumination sustainment rate is between short-term.
In order to solve above-mentioned problem, the utility model is a kind of long arc type discharge lamp, in luminous tube, disposes pair of electrodes relatively, being characterized as of this long arc type discharge lamp: in said luminous tube, enclosing has mercury (Hg), and the enclosed volume of this mercury is 0.5mg/cm

Wherein, in luminous tube, also can enclose comprise above-mentioned metallic combination more than 3 kinds or the metal more than 4 kinds.
About the ignition device of long arc type discharge lamp of the present invention, an example of its formation is shown in Fig. 2.
In the figure, the outlet side of AC power 21 is connected with boost rectifying circuit 22.
Boost rectifying circuit 22 for example is the rectification circuit that is made up of step-up transformer T1, rectifier diode D1, smmothing capacitor C1 that input side is connected with AC power 21, converts alternating current to direct voltage and exports.
Afterwards, this direct voltage utilization is boosted by the boost chopper that coil L3, switching device S1, rectifier diode D2, smmothing capacitor C2 constitute, to the direct voltage of polarity inversion circuit 23 outputs through smoothing.
Be connected with control circuit 24 at the switching device S1 of boost chopper (for example IGBT, FET), the switching frequency through making this switching device S1, and ON, OFF during change, can supply with desirable voltage.
Thus, can switch input power, through signal from control circuit 24, the different patterns of lighting a lamp such as the pattern of lighting a lamp when lighting a lamp pattern and standby when switching irradiation.
The polarity inversion circuit 23 that is connected with the outlet side of boost rectifying circuit 22 is the inverter circuits that are made up of for example bridgt circuit, is made up of switching device Q1～Q4 such as IGBT that connects with the bridge joint shape or FET.
ON, the OFF of the switching device Q1～Q4 of polarity inversion circuit 23 drive through the drive circuit that control circuit 25 is comprised.
Polarity inversion through as the polarity inversion circuit drive signal X of the drive signal of switching device Q1 and Q4, and carry out the action of ON, OFF as the polarity inversion circuit drive signal Y alternate repetition of the drive signal of switching device Q2 and Q3, make rectangular-wave alternating-current voltage be supplied to discharge lamp 1.
The beginning of lighting a lamp of lamp is moving through applying pulse voltage from 26 couples of starter coil L2 that are connected in series with lamp of starter circuit, the gas that is enclosed in lamp is carried out insulation breakdown carry out.
Method for using about possessing the light irradiation device that above lamp and ignition device thereof are arranged is explained as follows.
Though the structure for light irradiation device is not shown, but possesses above-mentioned lamp and possess the lampshade, speculum etc. of lamp light source device,, possess suitable transport etc. is arranged corresponding to workpiece (shone thing) as irradiation object.
In known method for using, the frequency of lighting a lamp of lamp is per to carry out about at least 1 hour Continuous irradiation for 1 time and lights a lamp, and needs preset time by lighting a lamp to illumination till stable again, does not therefore carry out in the time need not shining, making under powered action.
In the present invention, light a lamp with at least 2 patterns of the pattern of lighting a lamp with light a lamp pattern and standby through irradiation.
Irradiation is lit a lamp with predetermined input power such as for example rated power with the pattern of lighting a lamp; Standby with the pattern of lighting a lamp in; To light a lamp according to penetrating with the low input power of pattern of lighting a lamp; During this period not to the shone thing irradiation ultraviolet radiation, through anti-dazzling screen lightproof unit such as (shutter) with the irradiates light shading, the standby in order to economize powerization.
Dropping into the switching of power carries out through lamp light source device for example shown in Figure 2.Wherein, if the switching that can drop into power then is not limited to above-mentioned ignition device.
The sequential of switching is for example come automatic gauge through following action: the preset detection unit that is arranged on transport etc. through utilization; Detect workpiece and be transferred next situation; Detection signal is transferred into the control circuit 24 of lamp light source device, switches input power through control circuit 24.Perhaps, also can the sequential that be predetermined be inputed to control circuit through program.
Irradiation is alternately switched with the pattern of lighting a lamp with pattern of lighting a lamp and standby.About switching cycle, the time of lighting a lamp continuously in the pattern of lighting a lamp separately is in 1 minute, and for example, standby/lighting a lamp was about 30～50 seconds.The switching of the pattern of respectively lighting a lamp was with completion in about 0.5 second to 3.0 seconds.
As implied above lighting a lamp, thereby to carrying, carry next workpiece successively, when needs shine; Light a lamp with preset power; In the time need not shining, then light a lamp with the power that is lower than this preset power, do not shine and standby; Thus with service time generally speaking, province's powerization of the power of can realizing lighting a lamp.
But; Power switched as implied above and when lighting a lamp in the less long arc type metal halide lamp of amount of mercury, is switched to when high-power by small-power as previously mentioned; Lamp inclosure metal can take place squeeze into to the situation of luminous tube inwall, the result has the problem that amount of metal reduces of enclosing.
The variation of the voltage when changing, electric current etc. about the input power that makes long arc type discharge lamp, expression one example in table 1.
In this table, be 1 lamp about 150cm about interelectrode distance, represent input power, with the relation of voltage, electric current, current density.
[table 1]
| Gross power (W) | Voltage (V) | Electric current (A) |
| 12,000 | 1340 | 9.0 |
| 15,000 | 1376 | 11.0 |
| 18,000 | 1411 | 12.9 |
| 24,000 | 1463 | 16.6 |
| 30,000 | 1542 | 19.7 |
| 36,000 | 1600 | 22.7 |
Can know that through this table in long arc type discharge lamp, when power is increased, compare with the variation of voltage, change in current is bigger.
At this, when studying to the current density in the luminous tube that is formed with electric arc, the internal diameter of the luminous tube of long arc type discharge lamp is certain for roughly at tube axial direction, so the current density in the luminous tube depends on current value.That is along with the increase of power, current density can increase.
Because the electronics in the electric arc depends on current density with the collision number of times of metallic atom, so current density is when increasing, and the metallic atom that moves towards the luminous tube inwall can increase.
, follow its interior temperature of luminous tube and rise also insufficient after making the wink of its increase in power switched.Therefore, can think that less through the halogen quantity of gasification, near the halogen density the luminous tube inwall is lower, metallic atom is not caught and is squeezed into easily to the luminous tube inwall by halogen.
Therefore, the present invention is through regulation mercury inclosure metal in addition and the amount of substance of enclosing halogen, and the metal beyond the mercury is enclosed halogen comparatively galore relatively, improves near the halogen density of luminous tube inwall thus.
When near the halogen density the luminous tube inwall was higher, metallic atom and tyco electronics in electric arc and when flying here, combine with halogen had easily suppressed it and have been driven into to the luminous tube inwall.
Wherein, why with removing in the metal of mercury by regulation, be because mentioned above about the analysis result that is driven into the material to the luminous tube in, about mercury, almost do not observe and squeeze into to the luminous tube inwall.
Embodiment
Below utilize description of drawings to verify the experimental result of effect of the present invention.
Fig. 3 is the chart that the relation with the lighting a lamp the elapsed time of a plurality of long arc type discharge lamps (h) and illumination sustainment rate (%) compares.
At this, the illumination sustainment rate is meant, to the illumination of the light of predetermined wavelength, and the ratio of the illumination after the illumination when lighting a lamp beginning and the time of lighting a lamp arbitrarily, the illumination when lighting a lamp beginning is that benchmark is represented the data that obtain with percentage.In this experiment with the light of the wavelength of 365nm as object, measure through near the illuminance meter that this wavelength, has sensitivity.
Test employed lamp and be the long arc type discharge lamp that interelectrode distance is 1450mm, exchange with maximum rated power 34.8kW and light a lamp.Luminous tube is a quartz glass, and electrode is a tungsten.The difference of the detail specifications of each lamp details in the back.
The lamp of comparative example is enclosed mercury 260mg, iron 10mg, mercuric iodixde 55mg, bismuth iodide 45mg, xenon 6.7kPa in the luminous tube of internal diameter 22mm, be 0.48mg/cm with respect to the amount of mercury of luminous tube internal volume
3
The amount of substance M (mol) of the inclosure metal beyond the mercury in this lamp and the ratio H/M of the amount of substance H (mol) that encloses halogen are 0.99.
Shown in Figure 3 is, carry out standby that input power with lamp is respectively 11.6kW use the pattern of lighting a lamp with use for the irradiation of 17.4kW the difference power of the pattern of lighting a lamp be 1.5 times 2 light a lamp patterns whenever at a distance from 60 seconds switch light a lamp the time light a lamp the elapsed time (h) and the pass of illumination sustainment rate (%).
Can know that in the lamp of comparative example 450 hours illumination sustainment rate is 70%, with respect to lighting a lamp the elapsed time, the illumination sustainment rate sharply reduces.
The present invention 1 lamp is in the luminous tube of internal diameter 22mm, to enclose mercury 253mg, iron 10mg, mercuric iodixde 90mg, bismuth iodide 45mg, xenon 6.7kPa are arranged, and is 0.5mg/cm with respect to the amount of mercury of luminous tube internal volume
3Lamp.
The amount of substance M (mol) of the inclosure metal beyond the mercury in this lamp and the ratio H/M of the amount of substance H (mol) that encloses halogen are 2.1.
About this lamp, likewise switch lighting a lamp of the pattern of lighting a lamp with above-mentioned, the illumination sustainment rate after the result lit a lamp 1000 hours is 90%, after through 2000 hours, also shows 76% illumination sustainment rate.
That is, in this lamp,, therefore being present near the halogen density the luminous tube inwall through raising because H/M is 2.1, the inclosure metallic atom that flies to beyond the mercury of inwall combines with halogen, so prevents to be driven into to quartz glass.
The present invention 2 lamp is enclosed in the luminous tube of internal diameter 22mm has mercury 273mg, mercuric iodixde 24mg, thallium iodide 3mg, xenon 6.7kPa, is 0.5mg/cm with respect to the amount of mercury of luminous tube internal volume
3Lamp.
The amount of substance M (mol) of the inclosure metal beyond the mercury in this lamp and the ratio H/M of the amount of substance H (mol) that encloses halogen are 4.0.
About this lamp, likewise switch lighting a lamp of the pattern of lighting a lamp with above-mentioned, the illumination sustainment rate after the result lit a lamp 1000 hours is 96%, after through 4000 hours, also shows 92% illumination sustainment rate.
That is, even in the metal species of enclosing not simultaneously, also can bring into play the effect identical with the present invention 1 lamp.
In lamp of the present invention, further increase halogen quantity, H/M is formed in the present invention 3 of 5.0 the lamp, till 3000 hours, all show 96% illumination sustainment rate.But, at 3400 hours, one-sided electrode can be near sealing bending and can't lighting a lamp.Can think that this is to have produced the electrode corrosion that causes because of halogen.
But, be effectively to effects such as preventing the luminescent substance minimizing, 3400 hours life-span is enough in practicality, so H/M is that 5.0 situation page or leaf is the scope that can bring into play the effect of the utility model.
That is the scope of H/M is preferably 2.1≤H/M≤5.0, in this scope, and the effect of attainable cost utility model.2.1≤H/M≤4.0 more preferably have the effect of the electrode corrosion that can not take place to cause because of halogen in this scope.
Based on more than, enclose in luminous tube that mercury and amount of mercury are arranged is 0.5mg/cm
3In the following long arc type discharge lamp; With the amount of substance of the inclosure metal beyond the mercury be made as M (mol), the amount of substance that will enclose halogen is made as H (mol); When their ratio is that H/M is in the scope of 2.1≤H/M≤5.0 time; Near the luminous tube inwall, halogen and inclosure melts combine suppress to enclose metal and squeeze into to the luminous tube inwall.
Thus, can prevent to prevent the reduction of illumination sustainment rate as the minimizing of the inclosure metal of luminescent substance.
Especially; When use makes the ignition method that power frequently and significantly rises, reach and prevent to enclose metal and squeeze into, even use above-mentioned ignition method to the effect of luminous tube inwall; Also the illumination sustainment rate also is difficult to reduce, and therefore can realize province's powerization of the power of lighting a lamp of lamp.
In addition; Irradiation is dropped into the different pattern of lighting a lamp of power with light a lamp pattern and standby when 1 minute lights a lamp with interior the switching with at least 2 of the pattern of lighting a lamp; Even after becoming the wink of irradiation with the mode switch of lighting a lamp with the pattern of lighting a lamp by standby; Because near the halogen density the luminous tube inwall is high, therefore can prevents to enclose metal and squeeze into to the luminous tube inwall.
In addition,, also long-time illumination can be kept, therefore power consumptive province powerization can be made even the power climbing when being used mode switch to the irradiation of lighting a lamp to use to light a lamp pattern by standby is more than 1.5 times.
