Fluorescent Lamp BACKGROUND OF THE INVBITION
The present invention relates to a fluorescent lamp which cuts down self-absorption rate of ultraviolet ray in the central glass narrow tube narrower than a conventional glass tube and not only raises lu inous efficiency by restraining the ascent of an internal temperature in the both ends of a glass drum wider than the conventional glass tube and also improves the cooling effect in the glass tube by delaying the speed of black conversion phenomenon.
In general, the luminous source for illu~ination devides into an incandescent lamp system and a electrical discharge lamp system a~d the electrical dischar8e lamp system divides into a fluorescent lamp, a ~rcurial lamp and a hlgh voltage sodium la~p, and as a lighting equip ent for houslng, the fluorescent lamp is used.
The conventional linear type fluorescent lamp, as shown in Fig. 1 a base(5) is adhered at the glass tube(l) both ends which the internal as a diameter of D is e~ptied out in the full length of L2 is formed in a pins(10) interval of L1.

fluorescent material, the base(5) of the pin(10) is set up at the both ends, and a negative electrode(3) and a positive electrode(4) coated with the electronic radiation material ls equipped to the double coil type of tungsten filament.
Mercury and the gas of argon or krypton systen in a few mmHg of pressure are put into the glass tube(l) of the fixed cylindrical type in order to plan discharge easily.
In order to light up the conventional linear type fluorescent lamp ~ade up in the same uanner, the relevant voltage is applied between the pins (10) in the base of the glass tube, namely between negative electrode (3) and positive electrode(4).
At this time, an electric current flow into the filament of electrode(3) put in the glass tube, for beco ing~pre-heating, therefore the thercion is emitted, and then the thermlon ls transferred to the fila ent of positive electrode(4) by the electrlc field and the discharge is opened. The electron(4) accurred through the discharge strikes to tbe mercury atoc(7) of the vaporized mercury ~y the rise in te~perature put into the glass tube(1), and as the mercury atom(7) is excited with this, ultraviolet ray(8) is radiated to the wall side of the glsss tube(1).
Accordingly, after the ultraviolet ray radiated to the wall sides of the glass tube(1) which coated with the fluorescent uaterial .
(2) is absorbed to the above thin film fluorescent material(2), and then changed into the visible light(9) and then emltted to the outside and then the sufficient visible light(9) of the fluorescent lamp can be obtained.
As above descrlbed, the ultraviolet ray(8) which emitted by the excited phenomenon of the mercury atom(7) put in the glass tube(l) to get the sufficient visible light(9) occurs the self-absorption cases in large numbers before arriving to the thin film fluorescent material(2) provided the radiation distance to the fluorescent material(2) coated in the inside wall of the glass tubeis far away, therefore, the dia eter(D) of the glass tube(1) is necessary to be narrow suffciently small to reduce the self-absorption rate of the ultraviolet ray(8) in the glass tube(l).
However, in order to reduce the self-absorptlon ratet if the full length(L2) of the glass tube(1) is preserved and at the sa e ti~e, the diaceter is narrower than the existing diameter, the fluorescent material(2) coated in the inslde wall of the glass tube(1~ receives thermal, the luminous intensity under the influence of the temperature specific character of the fluorescent material(2) shows a drop in fficiency.
On the other hand, the electron radiation material coated at the filament of the negative electrode(3) is slowly dispersed so that . ~

If th~? lighting time is long in this state, a area of black conversion phenomenon came out are solwly widens at the both side walls of the glass tube.
This brings conductivity at the black conversion part of the glass tube (13 and not only hinders in the discharge, but drops off in lumincus efficiency at the black conversion part.

The dispersing phenomenon speed is Ve/P.D (Ve is the negative electrode falling voltage, P is gas pressure, D is the distance from negative electrode), and is inversely proportioned to the distance between the negative electr~de(12) and the glass drum(ll) wall, so that the distance between the negative electrode and the glass drum is widened and the speed of the black conversion phenomenon is delayed.
The glass drum(11) shown in Fig. 3 ls a cylindrical type tube of the diameter Dl larger than the diameter D of the glass tube shown in Fig. 1, an opening part as a type Bl has slightly bended inside and the base(l7) formed with a pin(18) of an interval L3 is easily inserted and adhered.
The other opening psrt of the ~lass drum is closed with the side wall and the hole(C3), to be inserted with the glass narrow tube(19) is formed, and on the outskirts of the hole(C3), the projection is f~rmed outside as a type B2 so as to deposit at the Klass narrow tube(l9) easily.
2 ~3 ~J .L ~ ~ 7 The part of B2 of the glass drum(11) and the glass narrow tube(19) are heaped and the coupling part is firmly deposited.
The glass drum(11) is to be inserted and deposited in the both sides of the gl8ss narrow tube(l9) with the dlameter D2 arrower than the diameter of the conventional fluorescent lamp as shown in Flg. 4, and then the fluorescent naterial of the thin fil~ is to be coated and formed in the inner wall of the glass narrow tube(l9) and the both sides of the glass dru~(11) as in the conventional one.
Each of the glass drum(11) becomes the deposited state in the both sides of the glass narrow tube(19) and the base(17) is adhered -to an opening part of the glass drum and the neKative electrode(l2) or the posltlve electrode(13) and the exhausted tube are adhered as the conventional fluorescent lamp. After the stem of the'electrodes(12,13~ are wldened the wing part of the A part and are deposited with the stem wider than the conventlonal stem as shown in Flg.3.
The inner parts of the both sides of the glass drum(11) and the deposited glass narrow tube(19) are to be exhausted and Dercury and an lnert gas are implanted, and the base(17) is adhered to the glass drun (11), as a result, the fluorescent la p of the present invention is completed.
Accordingly, the fluorescent lamp of the present invention has an overall length of ~2 ~L2 = 2Ls+ L6 and Lz > L6 > 2 L5, the glass drum(11) has a length of L~ ~here most of the black conversion part is in existance) and is the same as the overall length (L2) of the conventional fluorescent lamp and the interval between pins(18) interval of the base~17) is L3, it is possible to be substituted the li~hting fixtures using the conventional fluorescent lamp because L3 is same to the convention~l pins interval(LI).

The lighting operation for the fluorescent laop of the present invention composed as above described will be explaining as follows;
In order to light up the fluorescent lamp of the present invention, the appropriate voltage is applied between the negative electrode(13) and the 2~3li ~87 positive electrode(l3) among the pins(l8) in the base(l7) of the glass tube, but the electrical pheno enon is occurred as the conventional fluorescent lamp, and so the detail explanation of the lighting operation for the fluorescent lamp of the preseat invention will be o itted, only the operation occurred from the glass narrow tube(l9) and the both sides of the glass drum(l1) will be explaining First of all, in the electrical pheno~enon of the fluorescent lamp, a luminous efficiency is i-proved because a self- absorption rate of ultraviloe t ray becones narrower in the tube put with the dia eter D2 of the glass narrow tube narrower than the dia-eter of the conventional glass tube However, the heat occurred from the fluorescent material coated the wall of the glass narrow tube is conducted to the glass drun(ll) of the dia eter Dl wider than the diameter of t~he conventional glass tube deposited on the both sides of the glass narrow tube~19), so that a cooling effect ls elevated in this wide surface area Besides, the gas pressure in the glass narrow tube(19) and the glass drum(l1~ of the both sides can rise the effect of pressure control because the interval capacity of the both sides of the glass narrow tube(19) is largely formed The dispersing phenomenon of radiation aaterials occurred from the filament of the negative electrode instituted in the glass drum(11) can delay the black conversion phenomenon occurred in the vicinity of the filament of the negative electrode(l2) because the inner space becomes wider and the time can be extended owing to the glass drum of the diameter D~ wider than the diameter of the conventional glass tube. AccordinglY, the fluorescent lamp of the present invention can reduce the life owing to the blàck conversion in the glass drum(11) and the lowering of the luminous efflciency in the black conversion part.
The lossing heat owing to the heat which radiated from th e negative electrode is reduced because the distance between the filament of the negative electrode(l2) in the glass drum(11) and the wall of the tube is widely $ormed and the thermal efficiency of the fluorescent lamp can be improved because the temperature rise of the glass drum(11) with the wide diameter Dl is reduced. Accordingly, the luminous efficiency can be increased and the speed of the black conversion phenomenon can be delayed because the fluorescent lamp of the present invention can reduce the self-absorptlon rate of ultraviolet ray in the center glass narrow tube and the temperature rise of the inner part can be restrained.
In accordance with the present invention as the explanation the fluorescent lamp to reduce the speed of the dispersing phenomenon of the electron radiation material coated at the filament of the negative electrode can be provided because the self-absorption rate of ultraviolet ray can be reduced in the glass narrow tube and the speed of the black conversion phenomenon can be reduced in the both sides of the glass drum and the cooling effect, and the luminous efficiency in the narrow glass tube are increased, and then the center glass narrow tube narrower than the diameter of the conventional glass tube is deposited at the glass drum of the both sides wider than the diameter of the conventional glass tube, and the rising of temperature in the glass narrow tube is restrained and the sufficient space is in existence between the side wall of the glass drum and the negative electrode.
The present invention includes certain changes and modification without departing from the scope of the present invention as defined by the following claims.

Mercury and the gas of argon or krypton systen in a few mmHg of pressure are put into the glass tube(l) of the fixed cylindrical type in order to plan discharge easily.
In order to light up the conventional linear type fluorescent lamp ~ade up in the same uanner, the relevant voltage is applied between the pins (10) in the base of the glass tube, namely between negative electrode (3) and positive electrode(4).
