Description
The present invention relates to a kind of electric light, it has:
One has axis and the translucent bulb that is in the end on this axis:
The electrical equipment original paper of one bulb inside;
One has the Plastic lamp socket of axis, and it is equipped with electrical contact, and fixes around the end of described bulb, and this lamp holder has a housing, and this housing has an openend and the bottom relative with this openend around the described end of bulb, and the bottom has a contact at least;
The electric current that extends to the contact of lamp holder from the electric component lead of feeding;
Lamp holder and bulb have the flange and the groove of cooperation, and they have limited relatively rotating of lamp holder and have moved.
This electric light is known in GB1, and 240,346.
The lamp holder of this known electric lamp is a swan(bayonet socket) lamp holder, lamp socket adopts this lamp holder, and electrical contact is positioned on last two points that separate in bottom.In this known electric light, lamp holder has an axial slot at openend, makes the lamp holder flexibility that become in described end, like this, when lamp holder and bulb assembling, becomes at its openend and relatively to open, so that flange and groove can be meshing with each other.
A shortcoming of this known electric light is, when masterpiece was used on the lamp holder, because its flexibility, the lamp holder of finished product electric light can become once more to add and open, so that the cooperation place between lamp holder and the bulb contains is loosening.In order to eliminate this shortcoming, after assembly manipulation is finished, shut this slot with binding agent or cementing agent, this produces another year shortcoming again, such as using binding agent, in order with it lamp holder to be fixed on the bulb, just must be cured.
The Plastic lamp socket of another kind of swan type is known in GB2, and 152,746A.This lamp holder also has a slot at openend, will add thermal deformation after putting it to the end of lamp holder, with the flange of formation with the groove engagement of bulb.
GB1,380,720 disclose a kind of electric light of Plastic lamp socket, wherein, lamp holder adheres on the bulb, this lamp does not take measures to resist the torsion that is applied to cooperation place between lamp holder and bulb, thus this known electric light with binding agent fixedly the electric light of lamp holder compare and do not have what improvement in essence.
The present invention provides the electric light of the described the sort of type of a kind of opening paragraph for its purpose, one structure is arranged on the lamp holder of this electric light, except make lamp holder be easy to bulb assembling, also be suitable for forming the Edison lamp holder, in fact, the electrical contact of this electric light is made in the lamp socket near the arbitrfary point on the periphery of lamp holder bottom.
The electric light of the described the sort of type of opening paragraph has reached this purpose, and wherein, lamp holder has an axial parting surface and at first parts and second parts of these parting surface both sides, these two parts are that rigidity is interconnected.
This structure has a very big advantage, and existing swan lamp holder has the advantage of Edison lamp holder again, that is, except assembling rapidly, also make between bulb and the lamp holder to have good binding, and can provide a path that limits for the electric current lead of feeding by lamp holder.
Two parts of lamp holder can be connected to each other by associated means and be integral, and for example utilize the mechanical device resemble the snap.Like this, for instance, the flange of collaborative work can be made on first and second parts of lamp holder.Lamp holder with protuberance and groove part also is extraordinary embodiment, and wherein, the protuberance of each first parts of lamp and the groove of these another parts of lamp holder are arranged to clamping engagement.In one embodiment, some width reduces on the groove, and protuberance just passes through from this part.Usually, such one part that reduces width can cause that groove opens the outer surface up to lamp holder.
If snap is made in the open end of lamp holder, then parts of lamp holder and being connected of another parts, therefore, just lamp holder is tight especially with being connected of bulb.This is favourable for larger-diameter lamp holder, and 20mm or bigger for example because large diameter lamp holder compares with the lamp holder than minor diameter, must can sustain and don't influence the higher of minimum torsion setting that it combines with bulb to lamp holder.
Snap for example can be combined with the jockey at another place on the lamp holder at the snap of open end, for example the protuberance of manual engagement and groove.
Because lamp holder axially separates, the electric current lead of feeding can lead to the outside from lamp holder at an easy rate, is promptly prolonging the axial separation face and is reaching the outside.Loose current feed lines also no longer needs to extract by opening narrow in the lamp holder.
The further significance of lamp holder axial separation is that the combination between lamp holder and the bulb is very satisfactory.Therefore, lamp holder and bulb pin very satisfactorily and can not rotate mutually and move.Because axial separation, mutual combination does not need the elasticity of lamp holder between lamp holder and the bulb.Therefore, flange and the groove at bulb and lamp holder can be respectively high and dark.In the assembly manipulation process, in fact, two parts of lamp holder Clamp for take-down halogen lamp bulb in central and relative radial motion.
In preferred an enforcement, bulb and lamp holder have lateral trench and the flange that is used for axially cooperation, and like this, the outer rim of bulb end is not round, and the inner edge of the openend of lamp holder neither be justified, prevent mutual rotation in order to locking.
Flange and groove can be got such shape, and promptly the cooperation cross section of the openend of the end of bulb and lamp holder is a flat ellipse.Oval-shaped main shaft becomes vertical with parting surface, so the torsion that bulb is applied on the lamp holder is less to the load of the junction formation of Lighthead assembly.
End at lamp holder extends internally, and such as tapered, can make out protuberance, such as the shuttle-shaped column rib.This can the Lian diameter difference, like this, no matter the tolerance between bulb and the lamp holder how, all can obtain cooperation very close to each other.
In a preferred embodiment, bulb has first pair of mirror image groove and second pair of mirror image groove on the other side.The advantage of this groove is that its border is in the axial plane of bulb basically.Because these borders, the projection in the lamp holder end can hold on to bulb and prevent mutual rotation.If these projectioies have the surface of engagement substantially in the axial plane of lamp holder be favourable.
In another program of this embodiment, each projection is all linked on the lamp holder through an elastic wall.This scheme can be by realizing round each projection with the U-shaped slot on the lamp holder.In this scheme, regardless of the tolerance of diameter, all can make to reach between lamp holder and the bulb does not have the joint that rocks.The separation of lamp holder produces an advantage, promptly can make with the projection of groove engagement and needn't be bent to the more outside place, final position that should be in than them.
In the bottom of lamp holder, feed around electric current and to lead through forming a contact by for example welding.Yet, in a preferred embodiment, lamp holder has an axial projection on the parting surface of bottom, described electric current feed lead around this projection to back bending, simultaneously, one metal tube, for example brass or bronze block described projection and described electric current with clamping engagement and feed lead to form electrical contact.This contact has an advantage, does not promptly need welding operation (Sol-dering or Welding), thereby does not need to consider the cooling problem that occurs in the welded type contact in the use of electric light.Metal tube can have the tongue piece that stretches out, and this tongue piece can enter the lamp holder bottom.Therefore, further locking and prevented commentaries on classics of this metal tube with respect to lamp holder
The axial projection of lamp holder bottom can be recessed in the lower surface, makes metal tube outstanding from described surface just.Form cover shape if seal an end of metal tube, can form a flat horizontal contact-making surface.In addition, metal tube also can extend a longer distance from the bottom, forms pin shape contact, and this fruit can be sealed also and can not sealed its free end.This lamp holder can have two same contacts in the bottom, and two pin shape contacts can be arranged in fluorescent lamp, in the incandescent lamp of for example Swan lamp holder, two contact-making surfaces can be arranged.
In another embodiment, contact forms in the bottom by means of a metal dish, and metal dish is made of vertical projection tongue piece, and this tongue piece bifurcated inserts pass-through mode contact (Plercing contact) to form.Insert the pass-through mode contact technically and be commonly used to realize and being electrically connected of lead that it can be insulated also and can not be insulated.Under the situation of insulated conductor, also promptly be used for the situation of lamp of the present invention, the plug-in type contact passes insulation.
The bottom of lamp holder may comprise a channel shape groove, and when assembling during electric light, the electric current lead of feeding just penetrates wherein.Described groove can intersect with a cavity that holds the bifurcated tongue piece.In this way, the contact that is positioned at bottom centre can firmly fix.Yet this contact also can be provided with cylindrical end tangs, and the groove that this boss can be bumped into lamp holder is used for further fixing.
In Swan lamp holder or Edison lamp holder, under the situation of traditional metallic lamp holder, the housing parts of lamp holder any point and lamp socket near the periphery of its bottom electrically contact, and lamp head of the present invention is with preferred embodiment, and for example following mode forms.The electric current lead of feeding is stretching out from lamp holder near the bottom periphery place, and along the housing back bending of lamp holder.The becket of a U-shaped shaft section and bottom interlock, and block the housing of lamp holder and the electric current lead of feeding with clamping engagement.In an one modification, the housing of lamp holder has a continuous groove, and becket is crooked and be stuck in described groove.
In another embodiment, becket is shaped as ring-type U shape passage.Lamp holder can be established garden week groove near the periphery of bottom, the electric current lead of feeding stretches out from this passage, and this lead is along the housing back bending.Becket and the groove interlock of this garden week, and block this housing.
In another embodiment, lamp holder has a ring as second electrical contact contact with lamp socket, and this ring has a bifurcated tongue piece, and this ring and the electric current lead of feeding is coupled together with pass-through mode contact mode.This ring also can have one second tongue piece, and as the pass-through mode contact, it places a cavity of lamp holder, and fixes for ring provides another.Yet this ring can bend in the groove of shell of lamp base.The shape of ring can be a U shape tunnel-shaped, the U-shaped cross section, or be different shapes (for example taper), can have also and can not have cylindrical boss.
In the Edison lamp holder, the housing of lamp holder is a screw-type; In the Swan lamp holder, housing has two protuberances and is used for and the lamp socket mechanical engagement.
An advantage of synthetic material lamp holder is that it can avoid in the life-span of lamp lamp holder and lamp socket being welded together.This phenomenon can occur in traditional incandescent lamp bulb.When filament disconnects, can produce arc in the bulb.Because the current density of described electric arc is very high, may make feed fuse fusing in the lead of electric current.In lamp holder, thereby also may produce arc, this electric arc may jump on the housing of lamp holder, and described housing is fusion welded on the lamp socket.
Also may, feed arc on the lead of an electric current jumps to another electric current and feeds on the lead in lamp holder.The separation lamp holder of electric light provides and passes sealing lamp holder path separately for every electric current lead of feeding according to the present invention, and this two paths is separated from each other, and has avoided the arcing of arc in lamp holder from face.
In general Edison lamp holder, be formed with second contact, electric current feed lead by it at the openend of lamp holder through the outside, and be fixed on the lamp holder, this fixing point is wanted the distance of remarkable contact less than the bottom to bulb to the distance of bulb.Therefore, must cut down a part and feed the free end of lead along the bulb extension and contacted from described article one electric current lead of feeding to prevent electric current that this root may link to each other with principal voltage.
In the electric light with Edison or Swan lamp holder of the present invention, each contact to the difference of the distance of bulb less than foregoing the sort of form.In a preferred embodiment, electric current is fed lead to the length in the path of the contact of lamp holder cylindrical portion office, and promptly each contact is equal substantially to the distance of bulb.The relevant electric current lead of feeding also just needn't shorten.
Best, parts of lamp holder have one to cross groove on the parting surface of bottom, and another parts of lamp holder have one to cross projection on parting surface, and this projection cooperates with groove, and the electric current lead of feeding is enclosed in the described groove.Then, this root electric current lead of feeding stretches out from lamp holder at a point of determining, this makes the described electric current lead of feeding is mechanically fixed on the contact of lamp holder and becomes easy.This projection and this groove also prevent to make described electric current to feed lead between two parts of lamp holder, are connected thereby can not reach good with the contact of lamp holder.
This electric light also passes through the end radiant light of bulb, although amount is very little.In some applications, such as, in darkroom lamp, if the light that penetrates from the end of bulb spills along the axial separation face of lamp holder, this will be a shortcoming.In a specific embodiment, parts of lamp holder near openend, have the seam of accepting another parts at least.It is lighttight that this becomes lamp holder.
According to electric light of the present invention for example can be: incandescent lamp, halogenation incandescent lamp, low-pressure discharge lamp or high-pressure discharge lamp.In fact, the type of electric light is not main to the present invention.Electric component can be contained in the inner casing of bulb.
The dish type of the open end of lamp holder is elongated can be from said bulb laterally along stretching, and this elongation bends to for example parabola or ellipsoid.Its inner surface can the minute surface coating form one lamp/reflector element.
In the Swan lamp holder, if the radially protuberance that must cooperate with lamp socket is to be favourable by being fixed on that metallic pin in the lamp holder forms.Protuberance can connect pin by a bull and constitute.Suggestion, (all) pins will be enclosed in the lamp holder with synthetic material fully, collide with the electric current lead of feeding preventing.
Lamp holder can adopt various plastics to make, but the electric light that will the consider the sort of type lamp holder temperature that may reach at work.As an example, the thermo-plastic composite material has polyimide, polyether sulfone, polyether-ketone, the example with basic structure as shown in figure 16 such as polybutene terephthalate, polypropylene oxygen, polyphenylene sulfide, polyimides and polyamide.
