Description
Technical field
The present invention relates to incandescent lamp bulb and lighting device.
Background technology
Bulb is by making it luminous to the bung flange shape filament energising that forms of reeling with the tungsten monofilament.And the temperature of filament heals, and then luminous efficiency is higher for height.Yet the high more evaporation that promotes the tungsten of filament more of temperature produces thin and delicate part gradually in the filament, and bulb is to its lifetime limitation when these partial disconnections.
Therefore, the evaporation for the tungsten that suppresses above-mentioned filament further improves the purpose that luminous efficiency realizes long lifetime simultaneously, in common bulb inert gases such as argon gas is enclosed with nitrogen.And, because the inert gas of enclosing in this cell-shell also is that the big more then pyroconductivity of atomic weight is low more, can suppress the evaporation of tungsten, thereby, people replace to the argon principal component krypton principal component, the krypton principal component are replaced to xenon principal component inclosure cell-shell, in the hope of further improving luminous efficiency and realizing long lifetime.
And people know, suppose under the identical situation of the characteristics of luminescence (life characteristic) of above-mentioned bulb gained, and the volume of the big more then cell-shell of atomic weight of enclosing the inert gas of bulb can make more little, and the enclosed volume of gas is few more.For example, in the Patent Document 1 and 2 this is recorded and narrated, publicity can obtain good luminescent characteristic and life characteristic.
In addition, as Patent Document 3 was recorded and narrated, the lighting device that improves the characteristics of luminescence and life characteristic, can realize the bulb of cell-shell miniaturization and be equipped with this bulb also is provided to provide was purpose, have the bulb of hot line absorbing film on the surface of the bulb of enclosing xenon.

Yet,, when the enclosed volume in the glass tube ball increases, have the problem that arc discharge makes filament be easy to blow that takes place because the ionization voltage of xenon is low.For this reason, when in adding the incandescent lamp bulb that high voltage lights a lamp, enclosing xenon, and even that recommended is and with other inert gas rare gas such as nitrogen and/or krypton gas, simultaneously the shared ratios of xenon in all inclosure gases is set at below about 10 volume % in the past.But this kind bulb is difficult to give full play to the character that the script of xenon is hoped because of the enclosed volume of xenon is few.
The present invention carries out in view of said circumstances, even the incandescent lamp bulb that also is difficult to cause arc discharge, can brings into play the good light output characteristic and the life characteristic of lighting a lamp of lighting a lamp so that applying high voltage to be provided is its purpose.
Summary of the invention
The bulb that the invention of claim 1 is recorded and narrated is characterized in that this bulb possesses: the glass cell-shell; Possess and the tungsten monofilament is wound into several illuminating parts of bung flange shape and is connected with in the filament of the support between this illuminating part; At glass cell-shell internal support filament, to make the distance (A) between the two ends of filament be the importing silk of 5～20mm; Support between the illuminating part of filament is supported, makes the end of filament and the anchor lines that the distance between the support (B) is 8～8.5mm (ァ Application カ-Line); Enclose the inert gas of the xenon that contains 70～95 volume % in the glass cell-shell.
In the present invention and following each invention, specify as nothing, its term definition and technology connotation are as described below.
The glass cell-shell is PS type, S type, R type, G type etc., and its shape is not limit, in addition, the material aspect applicable to from soft glasses such as soda-lime glasss to hard glasss such as borosilicate glasses, quartz glass is also applicable.In addition, also cell-shell has been carried out the cell-shell that astigmatism such as silicon dioxide film are handled.In addition, also can make the surface of glass cell-shell be formed with optical diffusion film or reflectance coating, coloring film etc. according to needs.
At least be formed with 2 on the filament tungsten monofilament be wound into the illuminating part that the bung flange shape forms, between illuminating part and illuminating part, be formed with meristogenetic by the tungsten identical with illuminating part, almost be helpless to the support of luminous being called " leap portion ".Filament both ends when its support is subjected to the anchor lines supporting are subjected to the lead-in wire supporting, thereby, in cell-shell, be adapted to non-linear shape.Particularly be 2 occasion, supported with roughly being in the shape of the letter V at illuminating part.Illuminating part be wound into a weight, two-fold or triple bung flange shapes, energising the time rises to high temperature and red-hot luminous part, support is because of reeling to such an extent that evacuate temperature also almost non-luminous part when being lower than illuminating part, energising than illuminating part.So, the air line distance that connects between will the both ends by the filament of lead-in wire supporting is called A, and the distance between the support that will be supported by the end of lead-in wire supporting and anchor pole (ァ Application カ-) by filament is called B.
If the enclosed volume of xenon is few, then the inhibitory action to the tungsten evaporation rate is little, needs 70 volume % at least.In addition, if surpass 95 volume %, then make arc discharge begin voltage and significantly reduce, make that arc discharge is easy to take place because of the ionization voltage of xenon is low.Therefore, the optimum range of xenon enclosed volume is 75～95%, and the suitableeest scope is 90～95%.In addition, because the pyroconductivity of gas is different and different because of the kind of the inert gases such as krypton, argon or nitrogen that mix with xenon, thereby the kind of the gas of must foundation sneaking into be selected the enclosed volume of xenon.As the inert gas that mixes, it is also high that nitrogen cheapness and ionization voltage height, arc discharge begin voltage, thereby be easy to mix.
These enclose the inclosure pressure of the gas of glass cell-shell, are advisable with 65～101kPa under the room temperature.If discontented 65kPa, then because of luminous efficiencies such as heat insulation effect impaired meeting causing luminous flux reduce or the lost of life, thereby unsuitable.In addition, if surpass 101kPa, the worry that then exists soft glass to break, thereby unsuitable.
For the bulb that xenon is enclosed in inside, especially big and temperature is easy to take place arc discharge near rising to the both ends of filament of high temperature in potential difference.For this reason, the present invention is set at 5～20mm with the distance between the both ends of filament (A).Distance when between the both ends of filament is discontented with 5mm, then easily between the both ends of filament arc discharge takes place.When surpassing 20mm, then the illuminating part of filament and glass cell-shell near and make the rising of glass bulb temperature, have the worry of glass cell-shell generation deterioration.In addition, the optimum range of distance (A) is 8～15mm, and the suitableeest scope is 10～12mm.
In addition, the end of filament and the distance between support (B) are 7～10mm, are advisable with 8～8.5mm.Implication apart from B is: for the illuminating part that makes filament too near the distance of (occasion that has several supports then is between adjacent support) between glass cell-shell, support when being equipped on its non-rectilinear ground in the cell-shell behind the filament locality warpage and the connecting portion.Distance between the both ends of filament (A) is under the occasion of 5～20mm, if apart from the discontented 7mm of B, then because of the filament total length shorten can not reach fixed luminous flux, even for the occasion of having guaranteed enough filament total lengths, because must be for several times, thereby be difficult to the filament of the necessary length of illuminating part is equipped on common bulb with in the glass cell-shell with the filament warpage.In addition, when the distance B ultrasonic is crossed 10mm, distance A is being set under the occasion of 5～20mm, is being difficult to filament is equipped on common bulb with in the glass cell-shell.In addition, (occasion that has several supports is then between adjacent support) also has temperature rising or the big part of potential difference between support and the connecting portion, thereby, the possibility that above-mentioned discharge takes place is arranged.With regard in this respect, owing to will be set at 7～10mm, serve as better with 8～8.5mm apart from B, thereby, can suppress the generation of (occasion that has several supports is then between adjacent support) discharge between support and the connecting portion.
The invention of claim 2 is in the described bulb of claim 1, it is characterized in that, the end of distance between the two ends of filament (A) and filament and by the ratio B/A of the distance (B) between the support of anchor pole supporting in 0.5～0.8 scope.
The bulb that the invention of claim 3 is recorded and narrated is characterized in that this bulb possesses: the glass cell-shell; Possess and the tungsten monofilament is wound into several illuminating parts of bung flange shape and is connected with in the filament of the support between this illuminating part; At glass cell-shell internal support filament, to make the distance (A) between the two ends of filament be the lead-in wire of 5～20mm; The angle (θ) that supports, makes each adjacent illuminating part of filament to form to support is the anchor lines of 25～120 degree; Enclose the inert gas of the xenon that contains 70～95 volume % in the glass cell-shell.
For the bulb that xenon is enclosed in inside, arc discharge easily takes place when approaching the situation that the filament distance is near or potential difference is big that temperature reaches a high temperature.For this reason, with anchor lines support is supported, making the minimum angles θ that each illuminating part of filament forms (occasion of the filament that roughly is in the shape of the letter V that forms when illuminating part is 2 is meant the intersecting angle of each illuminating part of being seen filament when the perpendicular direction in the plane that constitutes with filament is observed) is 25～120 degree.If discontented 25 degree of this angle, then the distance between the illuminating part of filament is near, thereby is easy to take place arc discharge.If surpass 120 degree, then the illuminating part because of filament rises the glass bulb temperature near the glass cell-shell, and there is the worry of deterioration in the glass cell-shell.Have the occasion of the illuminating part (having several supports) more than 3 at filament, the situation of several angles θ occurs existing, this moment all angle θ are made as 25～120 degree and just can.
The bulb that the invention of claim 4 is recorded and narrated, this bulb possesses: the glass cell-shell; Possess and the tungsten monofilament is wound into several illuminating parts of bung flange shape and is connected with in the filament of the support between this illuminating part; Lead-in wire between the two ends of glass cell-shell internal support filament; To the anchor lines that the support between the illuminating part of filament supports, enclose the inert gas of the xenon that contains 70～95 volume % in the glass cell-shell, it is characterized in that the beeline of the center of the illuminating part of filament and glass cell-shell is between 12～16mm.
The glass cell-shell continues in the next deterioration that is easy to of the condition of high temperature, especially when temperature reaches more than 220 ℃, the chemical reaction of the surface composition of the moisture of external environment condition and glass cell-shell can take place on the surface of glass cell-shell, thereby has the worry that produces strain etc., the distance at the center of glass cell-shell and filament light-emitting portion must be made as more than the 12mm for this reason, reach a high temperature with the surface temperature that prevents the glass envelope shell.It is described herein that " " center " of filament light-emitting portion is meant the substantial middle of the luminous component of filament, the peak of expression temperature.In addition, if the distance of filament and glass cell-shell is greater than 16mm, then the size of glass cell-shell increases, and perhaps, filament forms the bearing increase that slightly is flat condition and makes filament.For example, in the occasion of the cell-shell that adopts the PS35 size, filament must be made bigger than the neck of cell-shell, thereby produce difficulty during fabrication, and problems such as filament etc. is yielding take place.
The invention of claim 5 is claim 3 or 4 described bulbs, it is characterized in that, filament is double bung flange shape, and secondary bung flange winding department distance is 140～180% with respect to the ratio (%P) of the one-level bung flange diameter of illuminating part.
The bung flange winding department apart from respect to the ratio (%P) of the one-level bung flange diameter of the illuminating part of filament if less than 140%, though then the output of incandescence can increase, but because of the excessive temperature of illuminating part rises, can promote the evaporation of tungsten, be difficult to guarantee the required life characteristic of common bulb (for example, the time of lighting a lamp till the filament broken string is 2000 hours).When greater than 180% the time, then the illuminating part temperature because of filament can not appropriateness rise, thereby is difficult to satisfy as the incandescent lamp bulb of enclosing rare gas and requires the general electricity-saving characteristic (for example 131m/W) that reaches.
