In this mounting end 3b, on the inboard ring-type convex stage portion 3c of the linking part of the circular cone ladder type portion of light cover body 3a and cylindrical portion, carry and putting and secure bond is propped up the cylindric openend in bottom of part 5.And, near this convex stage portion 3c, be formed with fastening recess 3d, be fastened and use buckling parts 5f, and the adjustment light cover is with axial (above-below direction among Fig. 1) displacement of buckling parts 5f at the hook-shaped light cover in cross section of the figure split shed lower end that is based in a part 5.
Prop up in the part 5; On baseplate part 5a, be equipped with and support recess and tubular jut 5c; Said support recess carries pair of electrodes hermetic terminal 4a, the 4b that puts and support luminous tube 4; Said tubular jut 5c is outstanding in these electrode hermetic terminals 4a, 4b gap each other, and the adjustment dislocation of part 5 on diametric(al).Baseplate part 5a constitutes: in the outside of this tubular jut 5c; Form through hole 5d, 5e respectively; And in these through holes 5d, 5e, penetrating the pair of electrodes hermetic terminal 4a from luminous tube 4, the short tubule 4c that 4b gives prominence to its outside, long tubule 4d and diagram abridged outside line (out wire) respectively.
And, as shown in Figure 3, in the part 5 the outer peripheral face of its cylindrical portion 5b respectively integraty be equipped with: light cover use buckling parts 5f, gives prominence to the horizontal direction outside of a part 5; And 5 g of upper process portion and the 5h of lower process portion, in this Fig. 3 above, as foam with fastener and outstanding to the horizontal direction outside respectively.
The 5h of lower process portion carries the undergauge open end 6d that puts foam 6, part 5 and foam 6 are positioned, and this foam 6 supports the load of this foam 6 up the time on gravity direction.
The 5g of upper process portion, the undergauge side opening end 6b that is connected to foam 6 because of its outer peripheral face front end goes up the inner peripheral surface of formed fastening stage portion 6b2, the diametric(al) of foam 6 is pushed to support make that foam 6 is unlikely to come off from a part 5.
The 5h of lower process portion outstanding flange (flange) both capable of using outwards waits and ring-type is dashed forward and established, and perhaps also can be on its ring-type circumferencial direction, to separate desired spacing and the projection that sets.The 5g of upper process portion is arranged on to have elasticity and forms the shell fragment front end that can rock.This shell fragment forms by forming the cylindrical portion 5b of slit with a part 5 in order to remove the part of running into fulcrum.
As shown in Figure 1; Foam 6 is the transparent of for example 1～2mm or the synthetic resin (for example polycarbonate, acrylic acid, polyethylene etc.) with light diffusing through thickness, and forms shape near the smooth curved surface shape of general lightings such as incandescent lamp bulb with the glass marble of bulb.That is, the binding of foam 6 integraty forms the approximate spherical globular part 6a and the reducing diameter part 6b of approximate circle tubular, the bottom of reducing diameter part 6b in Fig. 1 of this globular part 6a of said approximate circle tubular, and undergauge is that diameter is less than this globular part 6a gradually.Globular part 6a has the 6c of maximum gauge portion of the maximum gauge of expression foam 6.Reducing diameter part 6b is formed with undergauge open end 6d in an end of foam 6 (being the bottom among Fig. 1), and the edge part interlocking of this open end 6d is inboard at the opening mounting end 3b of light cover 3, is adhesively fixed by for example bonding agent such as silicones or epoxy resin.
And, foam 6 with the direction of the central shaft O quadrature of luminous tube 4 and lamp-bulb type fluorescent lamp 1 on be divided into two, just laterally be divided into two on (horizontal direction).That is, foam 6, is divided into two on the above-below direction in Fig. 2 as horizontal cut-off rule with the horizontal direction center line Oa of the 4k of maximum outside diameter portion of luminous tube 4, is divided into the upper end foam 6X1 of top ends 6a side and the lower end foam 6X2 of reducing diameter part 6b side.
Just when this foam 6 was formed by the integral body of the for example non-property cut apart, the external diameter of the 4k of maximum outside diameter portion of luminous tube 4 was greater than the external diameter of the undergauge open end 6d of foam 6, and therefore from then on open end 6d inserts luminous tube 4 in the foam 6.
Yet; This foam 6 is through said horizontal cut-off rule Oa; And horizontal partition is lower end foam 6X1 and upper end foam 6X2 up and down; Therefore can on a part 5, erect after the luminous tube 4, cover the outside of this luminous tube 4 respectively by lower end foam 6X2 and upper end foam 6X1 from said both direction up and down, and integraty formation after utilizing the ultrasonic waves welding with each other subtend face 6X1a of the openend of these two foam 6X1,6X2,6X2a secure bond.
That is, the horizontal direction center line Oa of the 4k of maximum outside diameter portion of horizontal cut-off rule Oa and luminous tube 4 is consistent, therefore available these up and down a pair of lower end foam 6X2, upper end foam 6X1 cover whole luminous tube 4.
And the 6X1b of interlocking portion, the 6X2b of this foam 6 also can constitute shown in Fig. 2 (B)～(D).Promptly; Among Fig. 2 (B); The thickness direction of the composition surface 6X1a of the foam 6X1 pars intermedia roughly in the upper end, the prominent cross sectional shape of establishing of integraty is that raised line 6X1d use in the interlocking of semicircle shape on whole horizontal cut-off rule Oa, and forms the circular-arc scarfing slot 6X2d in cross section that rabbets on this raised line 6X1d respectively.Among Fig. 2 (C), the cross sectional shape of this raised line 6X1d is have sharp-pointed leading section subtriangular, and the scarfing slot 6X2d of interlocking on this raised line 6X1d forms the cross section approximate trapezoid respectively, and the degree of depth is less than the projecting height of raised line 6X1d.Among Fig. 2 (D), the composition surface 6X1a that raised line 6X1d and the scarfing slot 6X2d of Fig. 2 (C) is formed on be displaced to foam, the thickness direction of 6X2a are roughly on the position of pars intermedia more lateral.Fig. 2 (E) expression utilizes the ultrasonic waves vibration, makes raised line 6X1d and the mutual fusion weld of scarfing slot 6X2d of Fig. 2 (C), and the state that makes upper end foam 6X1 and lower end foam 6X2 interfix and combine.6X3 representes the fusing department after raised line 6X1d and the scarfing slot 6X2d fusion, and this fusing department 6X3 extends to till the outer surface of foam 6.And, at residual some the composition surface 6X1a of foam 6 medial surfaces of fusing department 6X3,6X2a.For under the state of upper end foam 6X1 and lower end foam 6X2 secure bond, the shadow that lighting of luminous tube 4 projected in the process on the foam 6 is unshowy, and preferably making gap between composition surface 6X1a and 6X2a is 0.3mm or below the 0.3mm.Can make this gap as far as possible little; And for the closing line that makes the cut-off rule seam does not observe; Preferably there is not the gap; But when the fusing department of the formation on the whole 6X3 of 6X1a, 6X2a on the composition surface, then the part of fusing department can leak out to the outer surface or the inner surface side of foam 6, causes forming so-called " burr "." burr " machinable that projects to foam 6 outer surfaces is removed; " burr " but of the inner surface side of foam 6 then are difficult to remove; Therefore, and suppress the generation of " burr " even if be projected in the gap of the length t that the inner surface side of foam 6 can be unshowy yet by the shadow that forms closing line.This gap length t is preferably below 1/2 or 1/2 of thickness of foam 6, for example is 3mm or below the 3mm.
In addition, also can these be rabbeted raised line 6X1d and be arranged on lower end foam 6X2 side, scarfing slot 6X2d is arranged on upper end foam 6X1 side.The composition surface 6X1a of foam 6X1 and the composition surface 6X2a of lower end foam 6X1 got final product on just the 6X1b of interlocking portion, the 6X2b of foam 6 constituted and can suitably rabbet.
When the interior pressure in the foam 6 excessively rose, fusing department 6X3 also can play following effect, and its part separates divided by ventilating air-tightness to reduce pressure because of producing slight crack etc.Pressure in the foam 6 rise and are that gas by electronic component moment dischargings such as the electrolytic capacitors that reaches service life that is provided in the lamp device 7 in the light cover 3 causes.When this gaseous emission excessively rises the interior pressure of foam 6, there is following problem, when the air-tightness of foam 6 and light cover 3 etc. is higher, can produce the damage that these members break, fall and so on.Therefore, when interior pressure excessively rises, can be through being pre-formed fusing department 6X3 so that produce slight crack etc. among the fusing department 6X3, remove air-tightness and ventilate, to suppress the generation of this kind damage.
And luminous tube 4 comprises the 4e of spirality portion as the protuberance of said Fig. 1 middle and upper part, and the straight shape 4f of portion of bottom, and these members are that integraty links.The 4e of spirality portion generation type is following, and for example for the straight shape pipe shape glass bulb 4g of 10mm is bent into roughly two five equilibrium doublings, as the top, being wrapped on the not shown mould and making die forming is Double-spiral with the kink 4h of this five equilibrium position with external diameter.
Promptly; As shown in Figure 1, the 4e of spirality portion comprises the 1st the spiral double screw shape of portion of portion and the 2nd that spirals, and the said the 1st spirals portion from one of them electrode hermetic terminal of glass bulb 4g 4a for example; One side arrives among Fig. 1 the kink 4h of top as top ends around an O that the spirals one side of spiraling; Said the 2nd portion of spiraling is the other end of kink 4h from then on, and one side is spiraled around an O that spirals and simultaneously arrived for example 4b of another electrode hermetic terminal, and the required numerical example that spirals is as being (revolution) about 3 weeks.Therefore, the 4e of spirality portion forms the close closely spacing of spirals portion, and forms the long long discharge path portion of discharge path.In addition, the top ends of the 4e of spirality portion is kink 4h, also can form the diameter that makes said bulb (bulb) greater than the 1st, the 2nd protuberance of portion's diameter that spirals, and on this protuberance, form the coldest portion.
Pair of electrodes 4i, 4j use for example tungsten system coil electrode, are fixed on the both ends of glass bulb 4g at the state lower seal by the for example interim block of bead.
In glass bulb 4g, enclose discharge medium such as argon or krypton-85 gas are arranged,, be equipped with short tubule 4c and long tubule 4d with its internal communication at the outer surface of pair of electrodes hermetic terminal 4a, 4b.Mercury or mercury alloy in tubule 4d, have been taken in.
Process the 4e of spirality portion of protuberance; Be accommodated in the globular part 6a of top 6d side of foam 6 with the 6c of maximum gauge portion; And make the 4e of spirality portion screw diameter and foam 6 globular part 6a inner surface configuration accordingly, from the kink 4h on top to the 6c of maximum gauge portion hole enlargement gradually; Make screw diameter maximum at the maximum gauge portion 6c place of foam 6; In addition and the undergauge of the globular part 6a Lower Half of foam 6 accordingly, undergauge and integraty are attached at upper end among Fig. 1 of the straight shape 4f of portion gradually to make screw diameter.
The straight 4f of shape portion is at a pair of spiral terminal part of the 4e of spirality portion; Fig. 1 middle and lower part with the glass bulb 4g of pair of electrodes hermetic terminal 4a, 4b side; Axial below to the reducing diameter part 6b of foam 6 roughly is bent into the right angle; Make straight shape pair of electrodes hermetic terminal 4a, be set up in parallel the 4b almost parallel, and the support that is inserted into part 5 is with in the recess.The bulb external diameter C of the straight 4f of shape portion forms 7～9mm, and forms bulb D outer diameter less than the 4e of spirality portion (for example 8～10mm).In addition, the straight 4f of shape portion also can make glass bulb 4g slight curving and form helical form, so that be consistent with the direction of spiraling of the 4e of spirality portion.
In the lamp device 7, will be formed with the longitudinal substrate 7a that lights circuit pattern (pattern), and be embedded in the not shown a pair of cannelure of part 5 inner surface and fix.That is, in the part 5, at the inner surface of its cylindrical portion 5b, a part 5 axially on form on its diametric(al) relatively to a pair of cannelure (not shown), the Width both sides of the edge portion of longitudinal substrate 7a be embedded in the said cannelure and fix.Longitudinal substrate 7a constitutes single face or double-sided substrate, and on the installed surface of longitudinal substrate 7a, be equipped with electrolytic capacitor etc. lead-in wire part or transistor etc. chip element etc. light circuit component be a plurality of electronic component 7b, 7b ....
The specifics of the lamp-bulb type fluorescent lamp 1 that so constitutes constitutes one of example and is described below.Promptly; The luminous tube maximum outside diameter of luminous tube 4 (spiral external diameter) is 54mm, and the total height h1 of lamp-bulb type fluorescent lamp 1 is 109mm, and the height h2 of luminous tube 4 is 64 ± 1mm; The height h3 of maximum gauge portion 4 till the horizontal direction center line Oa is 38mm; Begin from the electrode sealed end of luminous tube 4, the diameter r1 of the 6c of maximum gauge portion of foam 6 is 60mm, and external diameter r2 in upper end is 32mm among Fig. 1 of light cover 3.Pair of electrodes 4i, 4j discharge path length to each other is 360～610mm, and because of the bulb diameter of glass bulb 4g different.For example, the diameter of glass bulb 4g (bulb diameter) is when being 8mm, and then discharge path length is 476mm, and when the bulb diameter was 9mm, discharge path length was 374mm.And the external diameter of bayonet socket 2 is 26mm, and luminous tube maximum outside diameter (30.5mm) is about 1.17 times of external diameter of bayonet socket 2.
Therefore, according to this lamp-bulb type fluorescent lamp 1, can obtain the outward appearance of approximate general lighting with bulb.
In addition, the 4e of spirality portion of luminous tube 4 is accommodated in the globular part 6a of relatively high capacity of the 6c of maximum gauge portion that comprises foam 6, therefore can enlarge bulb diameter and screw diameter together.Therefore, the discharge path of the 4e of spirality portion is extended, so can realize increasing the light beam among the 4e of spirality portion simultaneously and improve luminous efficiency.
And, be accommodated in the straight shape 4f of portion, the 4f of the luminous tube 4 in the narrow reducing diameter part 6b side of foam 6, because of the bulb D outer diameter of its bulb external diameter C, therefore can increase the straight shape 4f of portion in the foam reducing diameter part 6b, the gap around the 4f less than the 4e of spirality portion.Therefore, can reduce the luminous shading amount from the 4e of spirality portion and the straight 4f of shape portion, 4f of being covered by the straight shape 4f of portion, 4f itself.Thus, can improve luminous efficiency.
In addition, among the 4e of spirality portion, because of increasing bulb diameter and screw diameter together; So the die forming of mould is arranged and when glass bulb 4g is configured as spirality by use; The shaping simplification is improved, in addition, slight crack or distortion in the time of can reducing said spiral forming.Its result is to make the production of the glass bulb 4g with the 4e of spirality portion and rate of finished products all obtain to improve.
And, owing to the bulb diameter of the 4e of spirality portion that occupies luminous tube 4 most of discharge paths is bigger, therefore can reduce the starting voltage and the bulb voltage of luminous tube 4.Therefore, need not to improve the output voltage of lamp device 7, and can reduce the resistance to pressure of using part, reduce, in addition, can prevent or suppress the maximization of this lamp device 7 so can realize cost.
In addition, the 4e of spirality portion of luminous tube 4 forms spirality because of glass bulb 4g, so the light that sends of the inboard of the 4e of this spirality portion; Covered by the inner surface of said spirality glass bulb 4g itself easily; Make and radiate the light beam minimizing in the 4e of the spirality portion outside so far, but the straight 4f of shape portion extends to axial almost parallel ground in the reducing diameter part 6b of foam 6; Bulb external diameter C is also thinner, so light beam is less by the part that the straight 4f of shape portion, 4f cover.So, can increase the inboard light that is sent of the inboard and straight 4f of shape portion of the 4e of spirality portion from the reducing diameter part side (being lower side Fig. 1) of foam 6 light beam to external radiation.
And; According to this lamp-bulb type fluorescent lamp 1, foam 6 is by along cutting apart with the horizontal cut-off rule Oa of the axle right angle orientation of its central shaft (vertical axis) O quadrature, therefore when when the top ends side is observed; Do not observe the closing line of said cut-off rule seam; So can improve apparent aesthetic property, and said closing line shadow is difficult to projection, also can improve the cosmetic look in the process of lighting.
In the junction surface of the composition surface of horizontal cut-off rule Oa 6X1a, 6X2a, be formed with the 6X1b of interlocking portion, 6X2b respectively; Therefore the 6X1b of these interlocking portions, 6X2b can simply promptly rabbet into concentric shape through rabbeting each other, so can prevent or reduce the off-centre on composition surface.
And; When utilizing ultrasonic waves welding or Vibration Welding when the whole interlocking 6X1b of portion of this horizontal cut-off rule Oa of secure bond, 6X2b; This cut-off rule junction surface is formed on the axle orthogonal direction of foam 6; Promptly on horizontal (horizontal direction), therefore the curvature on the horizontal cut-off rule Oa is constant in the whole interlocking 6X1b of portion, the last almost fixed of 6X2b.Therefore; Through making lamp-bulb type fluorescent lamp 1 only apply the position and be rotated with respect to ultrasonic waves or vibration around its central shaft; Can be easy to make ultrasonic waves or vibration to apply the interval at position and horizontal cut-off rule junction surface, keep almost fixed at the whole interlocking 6X1b of portion, 6X2b.
Therefore, it is roughly even at whole horizontal cut-off rule junction surface that ultrasonic waves that exposes to horizontal cut-off rule junction surface or the irradiation of vibrating (adding) are measured, so it is uneven to reduce the welding at horizontal cut-off rule junction surface.
And; The cut-off rule of foam 6 is the horizontal partition line, therefore when carrying out said ultrasonic waves welding or Vibration Welding, can seize the axial two ends of lamp-bulb type fluorescent lamp 1 to the mode of axial inboard pushing on both sides by the arms; Promptly; The globular part 6a top of bayonet socket side one end and foam 6 becomes easily the support at lamp-bulb type fluorescent lamp 1 axial two ends, and can make the axial compressive force distribution approximate equality in a circumferential direction among horizontal cut-off rule composition surface 6X1a, the 6X2a.Therefore, can reduce the set intensity inequality that the ultrasonic waves welding among these composition surfaces 6X1a, the 6X2a is caused.Therefore, the assemble workability efficient of lamp-bulb type fluorescent lamp is improved, so can improve rate of finished products.In addition, utilize ultrasonic waves welding or Vibration Welding and make the said interlocking 6X1b of portion, the fusion of 6X2b integraty and secure bond in addition, therefore can keep the light transmittance degree at said junction surface and other part roughly the same.
And; With the maximum gauge portion of the maximum corresponding foam 6 of maximum gauge portion of the spirality diameter of luminous tube 4 in; Be formed with horizontal cut-off rule Oa; Even if therefore in this spirality luminous tube 4, form the maximum gauge portion 4K of spirality diameter,, also can this spirality luminous tube 4 be accommodated in the foam 6 easily to prolong discharge path greater than the protuberance of the diameter of the undergauge openend 6d of foam 6.Therefore, can increase the efficient of the assemble workability of lamp-bulb type fluorescent lamp 1.
In addition, in the said example, the situation of utilizing resin to form foam 6 is illustrated, but the present invention is not limited thereto, and for example also can be made up of glass.At this moment, also can be at the inner surface of glass foam 6, coating comprises the acrylic resin or the silicones of ultraviolet absorption material.As ultraviolet absorption material, comparatively ideal is any combination more than 1 or 1 of titanium oxide (Ti), zinc oxide (Zn), iron oxide (Fe), cerium oxide (Ce).
In addition, when foam 6 during, also can on photodiffusion material, mix the coating ultraviolet absorption material for transparent resin system.In view of the above, can prevent or reduce because of UV-induced resin variable color and fade or deterioration, and can give light diffusing.
In addition, also can on the inner surface of luminous tube 4 or outer surface, be coated with ultraviolet absorption material.When the inner surface to luminous tube 4 is coated with ultraviolet absorption material, at first, on the interior surfaces of glass of luminous tube 4, form diaphragms such as silicon dioxide or aluminium oxide; Secondly; To being coated with ultraviolet absorption material on this diaphragm, in addition, also can on this ultraviolet absorption material film, form fluorescent membrane.Perhaps, also can only be coated with ultraviolet absorption material, on ultraviolet absorption material, form fluorescent membrane.In view of the above, the silica composition that diaphragm capable of using suppresses to separate out from the glass of luminous tube 4 and the reaction of mercury, and ultraviolet absorption material film capable of using absorbs ultraviolet ray effectively.
Lamp-bulb type fluorescent lamp 1 is as shown in Figure 3; Lower openings end in Fig. 1 of a part 5; Form shell fragment by a plurality of slit 5ig, 5ig, 5if, 5if; Therefore foam is set on this shell fragment uses fastener 5f, simple formation capable of using and buckling parts, the fastener elasticity of giving a part 5 with buckling parts 5g, light cover.
And; Support the openend 6d of the reducing diameter part 6b side of foam 6 by the 5h of lower process portion of a part 5; And flexibly support the inner surface of fastening stage portion 6b2 of the reducing diameter part 6b of foam 6 in diametric(al) by the 5g of upper process portion of part 5; Therefore can strengthen and make rubber-like resin system foam reducing diameter part 6b side flexibly rabbet the interlocking intensity on a part 5; And these parts 5 can flexibly be rabbeted with foam reducing diameter part 6b, and therefore when said interlocking, it is damaged in possible trouble to prevent that one of them from occurring.Therefore, can improve rate of finished products and packaging efficiency.
In addition, in the part 5, near the fastening stage portion 3c of light cover 3, be formed with the hook shape light cover that the fastening hole 3d with light cover fastens and use buckling parts 5f, therefore can improve the assembling intensity of a part 5 and light cover 3.
Therefore in addition, the light cover of these parts 5 possesses hook-shaped barb with buckling parts 5f, in case fastening hole 3d is fastened on this light cover with after among the buckling parts 5f, then can limit its axially displacement of (being above-below direction among Fig. 1).
Thus, can reduce the inequality of the installation site of a part 5 and light cover 3, improve the installation site precision.In addition, luminous tube 4 can possess protuberance, and it has the maximum gauge portion of diameter greater than foam 6 reducing diameter parts, and bulb need not to be spirality.For example, also can be the curved bulb, this curved bulb is crooked laterally and luminous tube that form to be connected form.
