Concrete form of implementation
(the 1st embodiment)
(structure)
Fig. 1 (a) and Fig. 1 (b) are the skeleton diagrams of the metal halide lamp 20 of the present invention the 1st embodiment.
Shown in Fig. 1 (a), metal halide lamp 20 is that rated power is the high-intensity discharge lamp of 150W, and it has base 1, outer tube 2, stem lead 3a and 3b, feed body 4a and 4b, luminous tube 5, current limiting element 6, starts with lead 7, metallic plate 8, metallic plate 9, sleeve pipe 10, insulator 11, lamp holder 12.
In the discharge space of person in charge portion 5a inside, enclose inert gases such as metal halogen compound, mercury and the neon of regulation and argon at normal temperatures with the pressure of 13kPa, simultaneously with pair of electrodes (electrode 13 and electrode 14) configuration (with reference to Fig. 3) relatively.
Here, because bar-shaped feed body 4a and 4b are inserted on the luminous tube 5 longitudinal direction central shafts, therefore, metallic plate 8 and 9 can guide the described central shaft of luminous tube 5 on the central shaft of outer tube 2 by respectively feed body 4a and 4b being guided on outer tube 2 central shafts.
By metallic plate 8 and 9, outer tube 2 inside are separated middle body and these 3 zones, both ends for being provided with luminous tube 5.
Because the luminous tube 5 as light emitting source is positioned at above-mentioned central portion, the light that above-mentioned both ends irradiate from luminous tube 5 by metallic plate 8 and 9 blocking-up, i.e. radiant heat.
Thus, when lighting a lamp, the temperature at above-mentioned both ends is lower than luminous tube 5 middle bodies.
Shown in Fig. 1 (b), in metallic plate 8, designed the hole 8b that startup runs through with lead 7.
Starting with lead 7 is that linear diameter is the molybdenum wire of 0.2mm, and the one end is welded to current limiting element 6, twists on the thin tube part 5b, and its central authorities are configured to join with the periphery of the 5a of person in charge portion, and its other end is rolled onto near the thin tube part 5c of electrode 14.
Current limiting element 6 is resistance value (R
G) be the carbon protective film resistor of 20k Ω, the one end is welded to feed body 4a, and the other end is welded to and starts with on the lead 7.
Shown in Fig. 3 (a), on the two ends of current limiting element 6, add cap terminal 6a and 6b respectively, because the following reasons guarantees that the interval (L) between these cap terminals is 4.5mm.
Promptly, between starting, produce under the situation of insulation breakdown with lead 7 and electrode 14, between the cap terminal 6a of current limiting element 6 and 6b, produce big potential difference, if make current limiting element 6 play the normal resistance function, then prerequisite is can be owing to this potential difference produces insulation breakdown between cap terminal 6a and 6b.
Do not producing between cap terminal 6a and the 6b under the situation of insulation breakdown, between 6a and 6b, needing to guarantee certain insulation distance (rd).
The inventor finds, the result who tests for comprise metal halide lamp 20 (rated power 150W), in rated power is metal halide lamp more than the 50W, below the 400W, above-mentioned insulation distance (rd) is 4.5mm.
Shown in Fig. 1 (b), metallic plate 8 is provided with and starts the hole 8b that runs through with lead 7, for reason same as described above, with the diameter in this hole guarantee for and startup be more than the above-mentioned insulation distance (rd), promptly more than the 4.5mm with the insulation distance of 7 in lead.
As the drive circuit that drives metal halide lamp 20, design provides the power circuit (figure is outer) of power, is used for regulating the ballast (figure is outer) of modulating voltage and lamp current, is used for applying the igniter (outside the figure) of high voltage pulse when starting.
Shown in Fig. 2 (a), in case the energized circuit, just producing frequency is 60Hz, and crest voltage is 325V (+V
1,-V
1) sine voltage.
Igniter shown in Fig. 2 (b), near above-mentioned sinusoidal wave peak point, in the overlapping high voltage arteries and veins, is brought up to 4500V (+V with crest voltage for detecting the high circuit of operating of modulating voltage
0,-V
0).
During startup, between the electrode 13 and electrode 14 in luminous tube 5, though can not produce arc discharge at first, by described overlapping high voltage pulse, near starting, produce micro discharge, generate the initial stage electronics that between described electrode, produces arc discharge at the beginning with lead 7 and electrode 14.
(operation)
Fig. 3 (a) represents the figure of metal halide lamp 20 operating conditions just often.
Startup between electrode 13 and electrode 14 before the generation arc discharge has applied the high voltage pulse (+V of 4500V constantly between electrode 13 and electrode 14
0,-V
0), but owing to the electronics that helps to discharge is considerably less in the 5a of person in charge portion, therefore between electrode 13 and electrode 14, do not produce arc discharge.
On the other hand, if between starting, apply high voltage pulse (+V with lead 7 and electrode 14
0,-V
0), by the thin tube part 5c of ceramic, though but the isolated high voltage pulse in space because the end and the electric potential gradient between the electrode 14 that start with lead 7 become very big, therefore produces micro discharge in electrode 14 vicinity.
When this micro discharge, because said mechanism, electric current becomes minimum.
In the strictness, current limiting element 6 descends owing to the resistance value with 20k Ω produces voltage, but because current value is very little, so this voltage drop-out value is also very little.
Therefore, the voltage (+V that applies in the described end that starts with lead 7
A0,-V
A0) and above-mentioned high voltage pulse (+V
0,-V
0) change hardly.
In a word, current limiting element 6 can exert an influence to the value of high voltage pulse hardly.
Thus, no matter current limiting element 6 has or not, when starting, by overlapping 4500V the high voltage pulse (+V of igniter
0,-V
0), producing micro discharge at electrode 14 with between starting with lead 7, this micro discharge becomes the initial stage electronics that begins as arc discharge, produces arc discharge between electrode 13 and electrode 14.
Certainly, become under the very large situation, can not ignore the resistance value of current limiting element 6 in the resistance value of current limiting element 6.
Be applied near the electrode 14 startup with the voltage between lead 7 ends and the electrode 14 owing to reduce, can not produce above-mentioned micro discharge, also can not generate the initial stage electronics of arc discharge, then starting resistor rising.
In not causing the scope that starting resistor rises, the resistance value of above-mentioned current limiting element 6 is the values that obtain in the experiment, in the strictness, be not limited to the value of above-mentioned 20k Ω, when startability is estimated, preferably the resistance value of current limiting element 6 is defined as striding across below the maximum resistance (R2) of benchmark, promptly in the scope below the 1M Ω.(when the 5a of person in charge portion is damaged)
Situation when the 5a of person in charge portion is damaged then is described.
The operating conditions figure of metal halide lamp 20 when Fig. 3 (b) is the expression person in charge 5a of portion breakage.
The 5a of person in charge portion becomes the inner little pressure vessel of HTHP that be when lighting a lamp, because thermal fatigue, exist in the situation that breakage is caused in the crack that produces among the 5a of person in charge portion etc.
Follow this breakage, in the inside of outer tube 2, inert gases such as metal halogen compound, mercury, neon and argon flow out in the outer tube 2 from luminous tube 5.
Then, by making contiguous startup with the 5a of the person in charge portion damage of lead 7 and electrode 14 insulation and come off, the startup with potential difference all becomes with lead 7 and electrode 14 exposes state.
At this moment, because the 5a of person in charge portion breakage, the arc discharge between electrode 13 and the electrode 14 disappears, and modulating voltage rises, and the igniter that detects the modulating voltage rising is with high voltage pulse (+V
0,-V
0) overlap on the sine voltage.
That is, become with overlapping 4500V high voltage pulse be applied between electrode 13 and the electrode 14.
Its result produces insulation breakdown starting between C portion nearest with lead 7 middle distance electrodes 14 and the electrode 14.
In a word, only the moment that has applied high voltage pulse for causing the state of discharge (below be referred to as " pulsed discharge ").
In pulsed discharge, current value is little, then can not obtain the effect that is produced by current limiting element 6.
On the other hand, even in the pulsed discharge state, also can be owing to not stopping to apply high voltage pulse, and can be transformed into the arc discharge of the bigger electric current of outflow.
But,, therefore can not produce arc discharge owing to, will flow through the electric current that starts with lead 7 and be limited in below the required current value of arc discharge by current limiting element 6.
Be transformed into below the required current value of arc discharge in order to be restricted to, more than inventors confirm that in metal halide lamp 20 (rated power 150W) this resistance value R1 need be for 1k Ω.
Therefore, under the situation of the 5a of person in charge portion breakage, in order to prevent paradoxical discharge, and the scope that startability is maintained the resistance value of the required current limiting element of current level 6 is the scope of 1k Ω to 1M Ω.
(starting the method that mounts) with lead
At first as previously mentioned, metallic plate 8 and the insulation distance that starts with lead 7 need be guaranteed to be more than the insulation distance (rd), existing startup mounts in the method with lead, owing to the product accuracy error is difficult to guarantee therefore reappraise with the lead method of mounting for starting greater than this insulation distance (rd).
(existing startup with the method that mounts of lead)
Shown in Fig. 4 (a), existing startup mounts in the method with lead, at first, prepares straight line metal wire 1071, and its bottom is bent towards direction with metal wire longitudinal direction quadrature, processes with the number of turns of 1/2-3/4 circle.This moment, the internal diameter of bending was identical with the external diameter of luminous tube 105 thin tube parts 133 (with reference to Fig. 4 (b)), or than its big a little degree.By this processing, formation mounts the 107b of portion in the bottom shown in Fig. 4 (a).
Then, the portion 107b of mounting is hung on the thin tube part 133 in the luminous tube 105, metal wire 1071 is installed on the luminous tube 105.Then, the metal wire of installing 1071 is implemented bending machining (Fig. 4 (b)) along the neighboring of the person in charge portion 131 of luminous tube 105.
At last, the metal wire 1071 (1/2-3/4 circle) that curls along the outside of the thin tube part 132 of luminous tube 105 upsides.By this bending machining, be mounted on the thin tube part 132,133 at luminous tube 105 two ends mounting the 107a of portion, 107b, finish in person in charge portion 131 to mount operation (Fig. 4 (c)) with lead 107 along its outside startup that forms part 107e.
But, above-mentioned startup mounting in the method with lead, start with lead 107 with the state keeping or the conveyance of bending on luminous tube 105, start with lead 107 owing to be positioned on the position of leaving luminous tube 105, therefore apply external force on partly in the top and make its distortion easily.
Because this upper end is the part that is inserted into hole 8b, if this part distortion, then original position can be departed from by the prescribed path at 8b center, hole in the path, and existence becomes near situation with the distance of metallic plate 8.
After making luminous tube 105, just may begin to mount to start and use lead 107, making the operation of luminous tube 105 and mount the operation that mounts that starts with lead 107 on the luminous tube of making 105 is continuous activity relation, owing to can not implement, therefore from the operating efficiency aspect, not preferred.
(startup of the 1st embodiment with the method that mounts of lead)
In contrast, among the 1st embodiment,, adopt the mount method of the startup of following record with lead in order to reduce the problems referred to above.
Use Fig. 5 to illustrate that the startup in the manufacture method of relevant this 1st embodiment mounts method on the luminous tube 5 with lead 7.
Shown in Fig. 5 (a), in the metal halide lamp manufacturing method of present embodiment, will start be mounted on the luminous tube 5 with lead 7 before, make the face shaping that starts with the form fit luminous tube 5 of lead 7 implement bending machining.
Particularly, the diameter that will be made of molybdenum (Mo) be that the wire rod of 0.2mm is with respect to its buckling angle of 90 ° roughly.The wire rod that is bent forms in the number of turns (about 180 ° of bending machining) of (distance of determining by the face shaping of the luminous tube 5 that will mount) about 1/2 circle that curls on the position of certain distance and mounts the 7a of portion.Mount the crooked internal diameter of the 7a of portion or identical, or be than its big slightly size with the external diameter of thin tube part 5b in the luminous tube 5.
Wire rod mounts crooked once more about 90 ° of the beginning part of the 7a of portion, towards the bottom direction of Fig. 5 (a).Afterwards, on wire rod, implement the roughly bending machining of コ font.Being processed as the part 7c that becomes straight line in the position of コ font roughly, in vertical direction becomes along the part of the 5a of person in charge portion lateral wall on hanging up luminous tube 5 time.
Carry out after the bending machining of コ font roughly, once more towards the downward direction of Fig. 5 (a).
After crooked about 90 °, be that the number of turns (about 180 ° of bending machining) of 1/2 circle forms and mounts the 7b of portion, finish then to start with lead 7 with the wire ends volume.
In the drawings in the coordinate system shown in the bottom right, set the curling central shaft that mounts the curling central shaft of the 7a of portion and mount the 7b of portion to such an extent that on the z direction, have certain interval.The back will be described this.
Mount the 7a of portion and mount the crispation number of the 7b of portion, therefore be preferably discontented 1 circle owing to can utilize the elasticity of wire rod.
But, break away from simply and be not close to lead 7 to the startup on the luminous tube 5 in order to make once mounting, wish to form with the above number of turns of 1/2 circle as mentioned above to mount the 7a of portion, 7b.
Shown in Fig. 5 (b), mount through the startup of above-mentioned bending machining with lead 7 with state along the neighboring of luminous tube 5.
To start to hang on the luminous tube 5 and need not carry out bending machining constantly, can be only be installed on the thin tube part 5c of luminous tube 5 downsides will mounting the 7b of portion, will mount the 7a of portion and be installed in when upside thin tube part 5b goes up and implement at this with lead 7.
The startup that hangs on the luminous tube 5 is used lead 7 because as mentioned above when bending machining, make mount the 7a of portion and mount the 7b of portion each other curling central shaft skew and form, therefore, when mounting, mount the 7a of portion and mount the 7b of portion by turning back to the elasticity of original (freedom) state, thereby can not break away from from luminous tube 5 simply.
The form of this elastic reaction is roughly startup is mounted with lead 7 relative luminous tubes 5, has with respect to the angle on luminous tube 5 direction of principal axis with the straight line portion 7c in the lead 7 so that start.
Use Fig. 6 that the shape of bending machining startup afterwards with lead 7 is described.Fig. 6 is side view and the vertical view from look of the startup of expression after the bending machining with lead 7.
Shown in the side view of Fig. 6, startup that will be by bending machining is shaped to lead 7 wants the form that is suitable for luminous tube 5 face shapings that mounts.
But as mentioned above, just as shown above, starting with lead 7 be free state, hangs over 7a of the portion that mounts and the 7b of the portion that the mounts eccentric distance d only that hangs on the thin tube part 5c on the thin tube part 5b.
In a word, this eccentric distance d will start when mounting with respect to luminous tube 5 with lead 7, become to have elasticity, play to make to start the function that can easily not break away from from luminous tube 5 with lead 7.
At the circle internal diameter that mounts the 7a of portion, 7b is under the situation of 3mm, wishes apart from d to be the 3mm roughly the same with it.But,, need to be set numerical value into the best according to being used to start with the linear diameter of the wire rod of lead 7 and mechanical property value etc. for this numerical value.
As shown in Figure 6, the startup of having carried out the state after the bending machining is held in vertical direction with the straight line portion in the lead 7 (near the part of the 5a of person in charge portion of luminous tube 5) 7c.To start when being mounted on the luminous tube 5 with lead 7, owing to roughly became before 0 in the distance of flexural center between centers, this straight line portion 7c is subjected to strain, thereby as above has shown in Fig. 5 (b) and luminous tube 5 axial angles.
Like this, before being suspended on the luminous tube 5, carry out bending machining so that make wire rod become shape in advance along with the face shaping of luminous tube 5, when producing the needing of illuminated in combination pipe 5, begin, be installed on the luminous tube 5 with lead 7 if mount the startup that to have carried out bending machining, can reduce making the chance that starts with lead 7 distortion.
Thus, be difficult to produce the appointment predefined paths that starts among the hole 8b that breaks away from metallic plate 8 with lead 7, guarantee insulation distance (rd) easily.
In addition, and be the center wire rod that curls with luminous tube 5, or the existing manufacture method of carrying out bending machining compare, operating efficiency can be improved, thereby manufacturing cost can be sought to reduce.
As mentioned above, according to present embodiment, in metal halide lamp, even have the container of luminous tube 5 and the situation of the 5a of person in charge portion breakage, use between the lead 7 at electrode 14 and startup, owing to current value can be restricted to the degree that arc discharge is a paradoxical discharge that do not produce, therefore can not flow through overcurrent, can prevent 2 damages of ballast and outer tube 2 etc.
In the present embodiment,, be not limited to this though metal halide lamp 20 rated power are 150W, also can be with any one value more than the 50W, in the following scope of 400W as rated power.
This situation is when the 5a of person in charge portion is damaged, for the scope that prevents paradoxical discharge and startability is maintained the resistance value of current limiting element required on the present level 6 is the scope of 1k Ω to 1M Ω.
Though current limiting element 6 is carbon protective film resistors, is not limited to this, can also be the resistor of other types such as pellet resistance.
Though metal halide lamp 20 of the present invention has applied alternating voltage, can also apply direct voltage.
In metal halide lamp 20, apply under the situation of alternating voltage, can replace the carbon protective film resistor of current limiting element 6 with capacitor.
In a word, in AC driving, have impedance because capacitor is the same with resistance, thus identical with resistance, when the 5a of person in charge portion is damaged, can limits and flow through the current value that starts with lead 7.
In the present embodiment, be configured to join, can also be not do not join with the neighboring of luminous tube 5 but close with the neighboring of luminous tube 5 though will start with lead 7.
The structure of electrode and feed body also can be different with the foregoing description, and for example, electrode and feed body can also be single parts.
In the above-described embodiments, be that example is illustrated with the metal halide lamp, but can be equally applicable to have the high-pressure discharge lamp of the startup of close luminous tube configuration with conductor.For example,, be applicable to the present invention too, also can obtain effect same as the previously described embodiments for mercury vapor lamp and high-pressure sodium lamp.
Be used to start wire rod with lead 7, though used the material of forming as the molybdenum (Mo) of 0.2mm by linear diameter in the foregoing description,, used wire rod also is not limited to this.For example, in wire rod, can also use the material (also comprising alloy) that comprises at least a element of from molybdenum (Mo), tungsten (W), niobium (Nb), iron (Fe), selecting,, linear diameter is set at numerical value in the material according to the temperature strength etc. of resistance and machinery.
In the 1st embodiment, as shown in Figure 1, metallic plate 8 is provided with and starts the hole 8b that runs through with lead 7, though will and starting, this aperture guarantees for more than the above-mentioned insulation distance (rd) with the insulation distance between the lead 7, but this is to be used for implementing metallic plate 8 and to start an example that insulate with between the lead 7, can also use other structure with insulation effect same as described above.
For example, as shown in Figure 7, insulator 17 is embedded among the hole 8b of metallic plate 8, make its inner formation run through the structure of insertion startup with lead 7, thereby can guarantee metallic plate 8 and start the insulation distance of using between the lead 7, between starting, can not produce discharge, can play that electric current is limited in electric current restriction below the required current value of current limiting element 6 arc discharges with lead 7 and metallic plate 8.
(the 2nd embodiment)
(structure)
Metal halide lamp among the 2nd embodiment is identical with the metal halide lamp among the 1st embodiment, is such high-pressure discharge lamp: even under the situation of person in charge portion breakage, do not flow through overcurrent, can prevent 2 damages of ballast and outer tube 2 etc.
Fig. 8 (a) and Fig. 8 (b) are the skeleton diagrams of the metal halide lamp 21 of the present invention the 2nd embodiment.
Shown in Fig. 8 (a), metal halide lamp 21 is that rated power is the high-intensity discharge lamp of 150W, and it has base 1, outer tube 2, stem lead 3a and 3b, feed body 4a and 4b, luminous tube 5, blocking element 16, starts with lead 7, metallic plate 8, metallic plate 9, sleeve pipe 10, insulator 11, lamp holder 12.
These parts are almost identical with the parts that use in the metal halide lamp 20 of the 2nd embodiment, the metal halide lamp 21 among the 2nd embodiment and the difference of the metal halide lamp 20 among the 1st embodiment are that current limiting element 6 in the metal halide lamp 20 and metallic plate 8 are replaced by blocking element in the metal halide lamp 21 16 and metallic plate 8 respectively.
Blocking element 16 and metallic plate 8 are below described.
Shown in Fig. 8 (b), in metallic plate 8, designed the hole 8b that startup runs through with lead 7.
Blocking element 16 is the fuse of 0.5A for current capacity, and the one end is welded to feed body 4a, and the other end is welded to and starts with on the lead 7.
On the two ends of blocking element 16, add the cap terminal respectively, because the following reasons guarantees that the interval (L) between these cap terminals is 4.5mm.
Promptly, between starting, produce under the situation of insulation breakdown with lead 7 and electrode 14, the paradoxical discharge that the beginning back will be described between starting with lead 7 and electrode 14, in blocking element 16, flow through big electric current, because above-mentioned blown fuse, blocked electric current, still, had the situation that produces paradoxical discharge between two cap ends of blocking element 16 and between starting with lead 7 and electrode 14 by above-mentioned fuse.
Therefore, in order to prevent between above-mentioned two cap ends, to produce paradoxical discharge at least, that is,, need to guarantee certain insulation distance (rd) between above-mentioned cap terminal in order between above-mentioned cap terminal, not produce insulation breakdown.
The inventor finds that the result test is, comprises metal halide lamp 21 (rated power 150W), and observing above-mentioned insulation distance (rd) in rated power is metal halide lamp more than the 50W, below the 400W is 4.5mm.
The hole 8b that the startup identical with the 1st embodiment runs through with lead 7 is set on metallic plate 8, after the above-mentioned blown fuse, the diameter of hole 8b is guaranteed for more than the above-mentioned insulation distance (rd), be more than the 4.5mm, so that between the startup that runs through this hole 8b is with lead 7 and metallic plate 8, do not produce insulation breakdown.
As the drive circuit that drives metal halide lamp 21, design provides the power circuit (figure is outer) of power in addition, is used for regulating the ballast (figure is outer) of electric current, is used for applying the igniter (outside the figure) of high voltage pulse when starting.
The function of these power circuits and igniter is as illustrated among the 1st embodiment.
(operation)
Fig. 9 (a) represents the operating conditions figure of metal halide lamp 21 just often, and the operation of the metal halide lamp 20 among its content and the 1st embodiment is identical.
(when the 5a of person in charge portion is damaged)
Situation when the 5a of person in charge portion is damaged then is described.
The operating conditions figure of metal halide lamp 21 when Fig. 9 (b) is the expression person in charge 5a of portion breakage.
As previously mentioned, the 5a of person in charge portion becomes the inner little pressure vessel of HTHP that be when lighting a lamp, because thermal fatigue, exists the crack that produces among the 5a of person in charge portion etc. to cause the situation of breakage.
Follow this breakage, in the inside of outer tube 2, inert gases such as metal halogen compound, mercury, neon and argon flow out in the outer tube 2 from luminous tube 5.
Then, by making contiguous startup with the 5a of the person in charge portion damage of lead 7 and electrode 14 insulation and come off, the startup with potential difference all becomes with lead 7 and electrode 14 exposes state.
At this moment, because the 5a of person in charge portion breakage, the arc discharge between electrode 13 and the electrode 14 disappears, and modulating voltage rises, and the igniter that detects the modulating voltage rising is with high voltage pulse (+V
0,-V
0) overlap on the sine voltage.
Its result is starting the arc discharge that generation is caused by insulation breakdown between C portion nearest with lead 7 middle distance electrodes 14 and the electrode 14.
In this case, owing to reduce as the vapour pressure of the outer tube of discharge space, the modulating voltage step-down usually, is compared when lighting a lamp usually, and it is big that lamp current becomes.
Here, if the pulse current will light a lamp usually the time is made as I
L, by making the current capacity I of blocking element 16
HLess than I
L, starting when producing arc discharge between the C portion of lead 7 and the electrode 14, can block really to arrive and start the current path of using lead 7, thereby stop arc discharge, be i.e. paradoxical discharge.
As mentioned above, according to present embodiment, in metal halide lamp, even have the container of luminous tube 5 and the situation of the 5a of person in charge portion breakage, when the generation arc discharge is paradoxical discharge at electrode 14 with between starting with lead 7, owing to blocked current path, can not flow through overcurrent, therefore can prevent 2 damages of ballast and outer tube 2 etc.
In the present embodiment,, be not limited to this though metal halide lamp 21 rated power are 150W, also can be with any one value more than the 50W, in the following scope of 400W as rated power.
In the present embodiment, though the current capacity of blocking element 16 is decided to be 0.5A, be not limited to this, the lamp current when lighting a lamp usually is made as I
LThe time, satisfy making current capacity I at least
HLess than I
L
Though metal halide lamp 21 of the present invention has applied alternating voltage, can also apply direct voltage.
In the present embodiment, be configured to join, can also be not do not join with the neighboring of luminous tube 5 but close with the neighboring of luminous tube 5 though will start with lead 7.
Inventors are conceived to: shown in Figure 11 (c), existing startup lead 107, the arcing distance of its paradoxical discharge (rc) extends up to D portion, needs several minutes, therebetween, in ballast, flow through overcurrent, outer tube 2 becomes high temperature, produces 2 damages, if the generation time of this paradoxical discharge is in 10 seconds, then can not produce the function problem in the ballast, it is also envisioned that the breakage that can not produce outer tube 2.
Therefore, between starting, cause the situation of arc discharge, make to start usefulness lead 7 and actively fuse with lead 7 and electrode 14, promptly 10 seconds with the interior D portion that fuses in Figure 11 (c), and end paradoxical discharge.
In a word, there is no need to dispose blocking element 16 respectively separately and start, can in starting, have both the function of blocking element 16 with lead 7 with lead 7, thus simplified structure.
This situation by adjusting material and the linear diameter size that starts with lead 7, can be implemented the adjustment of the degree of fusing.
In the present embodiment, making startup is the molybdenum wire of 0.2mm for linear diameter with lead 7, but be not limited to this, especially, even will start with lead 7 being used as under the situation of blocking element 16 own, so long as it is just enough to possess conductor material and the linear diameter of bringing into play the required characteristic of block function by fusing.
The structure of electrode and feed body can be different with the foregoing description, and for example, electrode and feed body also can be single parts.
Although intactly described the present invention, should notice that to those skilled in the art various changes and modification all will be conspicuous by means of accompanying drawing.Therefore, without departing from the present invention, these change and modification all will be included in wherein.
