Abstract
A capped electric lamp according to the invention comprises a lamp vessel (10) which is closed in a gastight manner and encloses a light source. The lamp vessel (10) is surrounded by a glass outer envelope (20) which is fastened at an end portion (21) to a housing (40) by means of a coupling member (30), which housing in addition supports a lamp cap (50). The coupling member (30) is made of metal, and the end portion (21) of the outer envelope (20) is fused to the coupling member (30). In the lamp according to the invention, the coupling member (30) is of a simple construction while nevertheless a blown outer envelope (20) can be used.
Description
The present invention relates to Capped electric lamp, this Capped electric lamp comprises lamp house, and lamp house is with the air tight manner sealing and encase light source, and lamp house is also surrounded by glass shell, and the end of this glass shell is fixed on the lamp socket by a male part, and lamp socket also supports a crown top of burner.
Usually adopt mould pressing process to make the glass shell of this lamp described in the introductory song.The shape of product that mould pressing process allows to make has the bigger selection degree of freedom.Plastic shell can be well secured on the male part it.On the other hand, available technological process for blowing is easily made the shell that wall thickness is thin, weight is lighter.This demonstrates the attraction of blow-molded glass shell, especially for compact fluorescent lamp.
EP 210 361 has disclosed this lamp described in the introductory song.This known lamp is a compact fluorescent lamp, and the arc chamber that bends to compact shape is arranged in the shell.Male part is installed in the shell and by synthetic resin and makes, and it disposes colluding of outward radial extension.Each hook is connected thereby the hook of male part forms interlocking jointly with shell body behind housing main body.Just be enough to obtain shaping shell in the lamps known with technological process for blowing., the shortcoming of this lamp is that the male part structure is complicated.
The object of the present invention is to provide this lamp described in a kind of introductory song, it has male part simple in structure, can also use the blow-molded glass shell simultaneously.
According to the present invention, be used for this lamp described in the introductory song of this purpose and be characterised in that male part is made of metal, the end welding of shell is on male part.This makes not being connected between shell and the male part rock, and shell and male part are with respect to all having simple shape based on being connected of interlocking form.
Male part can include the metal that is equivalent to the glass shell coefficient of expansion, for example under calcium oxide glass condition, uses the GrNiFe alloy, and its content such as Gr are that 6wt%, Ni are 42wt%, and all the other are Fe.Using the hard glass shell, during as Pyrex, can use as Ni/Fe or NiCoFe, for example content is that Ni is 29wt%, and Co is 17wt%, and all the other are Fe.
Lamp socket can be by preparations such as polybutylene terephthalate (PBT), Merlon or polysulfones.
Male part can comprise each separating belt of welding shell., the feature by the most preferred embodiment of lamp of the present invention is that male part is ring.Promptly the single part with robust construction has obtained male part.
The feature of the most preferred embodiment of lamp of the present invention is, the end welding of shell is on the endless belt of ring, and this endless belt is widened along the direction from shell to the crown top of burner.Shell makes its body be fixed on the becket easily in the lamp manufacture process, and relevant parts automatically are on the mutual concentric position.
For example use bonding agent, ring can be fixed on the lamp socket.Feature by the embodiment of lamp of the present invention is, ring has one or several marginal portion that centers on endless belt, this marginal portion to leave the crown top of burner to lean outward and tiltedly extend, and cooperates with the inwardly outstanding reinforcement of one or several lamp socket.This embodiment by lamp of the present invention more easily makes.Male part is pressed in the lamp socket, is about to easily be fixed in lamp socket with the male part of shell.Because the edge part of ring extends along leaving crown top of burner direction, thus they can be easily reinforcement by lamp socket.The marginal portion is by after the reinforcement, with itself being hooked in after the reinforcement, so male part and arc chamber are securely fixed on the lamp socket.
For example, form the interior impact thickness portion of one or several lamp socket with inwardly outstanding annular flange flange.Perhaps, for example these reinforcements can constitute some beads.One or several edge part that is tilted to outer ring can be tongue.Perhaps, the endless belt of the edge part cone form of also blocking.For example, this endless belt directly merger becomes previous mentioned endless belt, perhaps carries out merger by the ring-type transition band.
Light source in the lamp house for example is arranged on as inert gas of nitrogen and so on or the incandescent body in the rare gas.Lamp house can comprise for example halogen of bromine and so on.Among the embodiment, light source is ionogenic medium, and for example by the electric conductor of pair of electrodes or winding, it is in discharge condition at lamp duty cycle chien shih.Ionogenic medium comprises inert gas, comprises in addition as the transpirable composition of mercury and so on.
Glass shell can be for coarse, as be corroded or be provided with powder bed, so that the light of scattering light source.When for example light source was the UV source, this shell surface within it was provided with fluorescence coating.Perhaps, shell can be transparent, only as heat guard.This is important for the lamp that is used for cold environment.Among the embodiment, on the surface portion zone of shell the reflector can be set.
To illustrate in greater detail these and other aspect of Capped electric lamp of the present invention with reference to accompanying drawing, wherein:
Fig. 1 is an embodiment partial perspective and axial part sectioned view;
Fig. 2 illustrates the details II among Fig. 1;
Fig. 3 illustrates the details of the section of getting along III-III line among Fig. 2;
Fig. 4 is the profile of getting along IV-IV line among Fig. 1.
The Capped electric lamp that is shown among Fig. 1 comprises lamp house 10, and lamp house 10 is with air tight manner sealing and ambient light source.Herein, lamp house 10 is for curving hook-shaped tubulose lamp house.Light source in the lamp house 10 is ionogenic medium, and duration of work produces gas discharge by pair of electrodes 11a, 11b in this medium.Here, lamp house 10 is filled mercury and rare gas, and as shown in phantom in FIG., has also disposed the inner surface that luminescent layer 12 is arranged.The glass shell 20 that lamp house 10 is blown surrounds, and glass shell 20 is fixed on the lamp socket 40 by male part 30 in its end 21, and lamp socket 40 also supports the crown top of burner 50.Fig. 2 illustrates enlargedly by male part 30 shell 20 is fixed on details on the lamp socket 40.The power supply unit (not shown) of light source is contained in the lamp socket 40 and is connected to the electrical pickoff 51a of the crown top of burner 50,51b.
In the illustrated embodiment, male part 30 is rings, end 21 weldings of shell 20 on ring 30 endless belt 31, this endless belt 31 along from shell 20 to the crown top of burner 50 direction widen.
In addition, the edge part 32 of ring 30 is another endless belts, is connected on the above-mentioned endless belt 31 by transition band 33.Endless belt 31, transition band 33 and another endless belt 32 common grooves 32 that constitute the end 21 that holds shell 20.
During lamp shown in the shop drawings, can in the following manner shell 20 be fixed on the ring 30.At first, preheating shell 20 then, will encircle 30 and place near shell 20 ends 21, with instrument end 21 be pressed on the endless belt 31 of ring 30.Then, heat the end 21 of shell 20 again, up to its glass melting on endless belt 31.After shell 20 fully cools off,, be about to encircle 30 and be pressed into lamp socket, pass through the reinforcement 41 that lamp socket 40 is inwardly given prominence to up to the edge part 32 that encircles 30 with lamp socket 40 assemblings.This assembly operation of the one ridge 41 of reinforcement 41 ' help.
