Description

Title of the patent application

Electric lamp with an outer bulb and a built- ^¬ lamp

Technical area

The invention relates to an electric lamp, comprising a built-in lamp arranged in an outer bulb and a base, wherein the base with power supply ^¬ wires of the integral lamp is electrically connected. The invention further relates to a one-sided gesockel- te electric lamp with a salaries ^¬ th in a base outer piston and at least one inside the outer piston ^¬ arranged integral lamp, preferably a high-voltage halogen lamp.

State of the art

For general lighting electric incandescent lamps are known, which consist of a halogen built-in lamp, an outer ^¬ piston and a base. Halogen lamps consume in order to achieve the same brightness, ge ^¬ genüber conventional incandescent energy much less energy. In order to facilitate the conversion from energy-consuming incandescent lamps to halogen incandescent lamps, these halogen incandescent lamps are provided with the same sockets (eg E27, E14, etc.) as the incandescent lamps, so that they can be used in existing luminaires.

In such lamps, a frame is provided on the plate base for holding the integral lamp, wherein the disc base is fused with the outer bulb. The power supply wires protruding from the built-in lamp are connected via con- Clock wires electrically connected to the contact points of the base. The connection is made by soldering or welding on the one hand with the power supply wires of the integral lamp, on the other hand, for example, with the base sleeve and an electrically iso ^¬ profiled of the base sleeve center contact. The preparation of such a lamp has been very expensive.

DE-A 10 2005 051 076 discloses a holder for egg ^¬ ne built-in lamp, which consists of a metallic mounting clip, in which the built-in lamp is inserted. The mounting clip is attached to the glass plate base of the outer bulb, which is very expensive, since the glass base is a very complex component, which includes, for example, exhaust tube and melted supply wires. Furthermore, the metallic retaining ^¬ tion is visually very conspicuous, and interferes with the contacts of a classic bulb ^¬ rectangular, transparent appearance significantly.

Presentation of the invention

The invention has for its object to simplify the production of a lamp consisting of a built-in lamp, a So ^¬ ckel and an outer bulb. The invention is also based on the object of the invention to provide a single-ended electric lamp with a base attached to an outer bulb and disposed within the outer bulb built-in lamp, which is robust and easy to manufacture.

Preferably, the integral lamp is a high-voltage halogen incandescent lamp with pin base, wherein at least two pins act as power supply wires. This object is achieved in a lamp according to the preamble of the main claim by a special clip connection between base and built-in lamp.

The integral lamp essentially consists of a hermetically sealed lamp vessel, of at least one light source and a power supply system for the light source, which usually consists of two pins, which protrude from a pinch of the integral lamp parallel to the axis. The luminous means is normally a body, but it can also be a discharge arc between two electrodes. In the following, the light source will always be described as a luminous element for the sake of simplicity.

The power supply system connects the arranged in the interior of the lamp vessel filament with a arranged outside the lamp vessel base, which is to be connected to a power source. The power supply system consists, for example, of inner power supply wires, of fusing films and of outer power supply wires, wherein the mutually aligned ends of the inner and outer power supply wires and the power supply wires interconnecting fusing films are sealed in the lamp crimp. Relevant to the invention is only the pinch and the outwardly projecting pins. The built-in lamp is usually filled with an inert gas and a Halogenzu ^¬ set. Instead of a light bulb as well as a high pressure discharge lamp can be used as a built-in lamp ^¬ to, as in DE-A 32 32 207..

The joke of the invention is that a high degree of compactification is achieved in that the outer - A -

Power supply of the built-in lamp not as usual now ^¬ connected directly to the base, but via a mounting clip that folds the connecting line, so to speak, and thus shortens the length of the lamp. For this purpose, the external power supply of the integral lamp ends as short pins (pins). The mounting clip contacted egg ^¬ NEN pin, however, has a wing piece, which makes contact to the reasonable arranged outside the volume of the pinch seal and to below the projected volume of the pinch seal end of the socket contact. Essential for the shortening is that there is a sectional plane in which the four electrical supply lines, namely the two outer power supply lines and the associated base contacts, have no physical contact with each other. Rather, this contact is made in each case by the mounting clip.

The novel mounting clip has as essential Bestandtei ^¬ le a contact surface for the external power supply, a connector and a wing piece, which establishes a connection to the socket contact.

Preferably, the contact surface is connected to a retaining bracket for mounting on the pinch. The headband is preferably designed substantially U-shaped with two legs and a base part. Preferably, the contact surface is attached to the base part. This is realized in particular in that a downwardly angled tab is attached to the side of the base part. The tab is aligned parallel to the axis of the power supply and is applied to this. Then it can be welded to the power supply. Preferably, in the area of the bend between the base part and the flap, a hollow is inserted. directed, which serves as a threading aid for the power supply.

The two legs of the securing bracket engage around the Quet ^¬ research and are each at on one of the broad sides of the pinch. In this case, preferably at least one of the headband is designed so that it is corrugated and acting as a retaining spring. He is locking on to the Quet ^¬ research. The base member abuts either on the underside of the pinch or is spaced approximately parallel thereto. As a stop serves in this case a knob on the pinch. In this case, an extended, bent edge of the base part can be used for striking. This edge extends in the plane of the legs, but is wider than the headband, so that the additional width accomplishes the stop.

Preferably, the Ver ^¬ binding piece is arranged laterally on one of the headband. It leads to the wing piece. This is designed so that it ensures a secure contact with the socket contact. The contacting is preferably purely mechanical. The concrete Reali ^¬ tion can be done in several ways. In one embodiment, the wing piece is again a holding ^¬ bracket. However, it is better designed so that a Ba ^¬ sisteil not cross, but along the axis of the current is supplied, but parallel thereto, is arranged. The two legs are designed so that a leg is arranged parallel to the broad side of the pinch, and rests against the ^¬ ser. To position the socket contact, it is equipped with two ribs parallel to the socket contact. The base contact can be positioned in the valley between the two projecting ribs. A clamping contact of the socket contact is achieved in that the second leg is designed again as a resilient clamp. Advantageously, he has a slightly inwardly angled free end. This pinches the base contact between the two legs and pushes it into the valley between the two ribs, where it fixes it.

In another embodiment, the wing piece is shaped so that it can loosely surround the socket contact like a U-rail. The clamp is attached laterally to the edge of the U-rail and angled so that the resilient free end points into the U-rail. In this way, the clamp can fix the socket contact in the U-rail. Because of the lateral arrangement to the U-rail, it is particularly advantageous if the free end of the clamping bracket has a rounded recess which faces laterally in the direction of the socket contact.

Preferably, two such mounting clips are used to each connect an external power supply of the recessed lamp with a socket contact.

In particular, an outer bulb is used which is closed on the base side with a plate foot. The free end of the Sockelkon ^¬ contacts protrude mast-like from the disc base.

Preferred embodiment of the invention

1 shows a lamp according to the invention 1 in a ^¬ losionsdarstellung Exp. In a base 5 of the commercial type E27, an outer bulb 6 of the type A55 is held. Within the outer bulb 6, a built-in lamp 2 is arranged such that a luminous body 3 of the integral lamp 2 approaches approximately at the point inside the outer bulb 6. finds, is also arranged on the lamp in a conventional light bulb. The built-in lamp 2 is designed as a so-called high-voltage halogen incandescent lamp and known as such from the prior art.

The lamp 1 has a longitudinal axis A. The built-in lamp 2 is equipped with a plate base 39 as a structural unit, protrude from the socket contacts 30 in the direction of the base.

A built-in lamp 2 is shown in Figure 2 in detail by 90 ° ge ^¬ rotates. It is, for example, a one-side crushed halogen incandescent lamp. This halogen incandescent lamp has a lamp vessel 10. The luminous element 3 is electrically conductively connected to the base 5 via a power supply system. The power supply system is composed of inner power supply wires 11 connected to the luminous body 3, fusing films 12, and outer power supply wires 13 made as short pins. The ends of the inner power supply wires 11 facing away from the luminous element 3, the fusible foils 12 and the ends of the outer power supply wires 13 facing the fusible foils are fused in a lamp pinch 14 closing off the lamp vessel 10. The pinch is as known per se with two narrow sides 15 and two broadsides 16 equipped. The pinch 14 is preferably designed in a so-called double T-shape, with a protruding bead 17 on the side edges.

The lamp vessel 10 is filled with an inert gas and Halogenzu ^¬ set. At its end opposite the lamp crimp 14, the lamp vessel 10 has been melted off. The lamp vessel 10 is hermetically sealed off to the outside. The built-in lamp 2 is according to Figure 3 of two mounting clips 20, see in detail Figure 4, held. The two mounting clips 20 are preferably identical, but need not necessarily be. Each clip has a contact surface 21 for the external power supply 13, which is formed substantially as a rectangular plate on. It is pa rallel ^¬ arranged to outer power supply 13 and is located externally to at its end.

The contact plate 21 is part of a base part 22 and bent at this right angle. The base part 22 is a spring strip and itself part of a U-shaped bent bracket 23 made of spring steel, which has two legs 24a, 24b of the "U" next to the base part 22. The base part 22 is arranged transversely to the longitudinal axis A and lies approximately at the underside of the pinch seal 14. The two legs 24a, 24b of the retaining clip 23 are tweezer-like at the two broad sides 16 of the pinch, starting from the base part 22. The retaining clip is adapted in its dimension to the pinch to facilitate the Einfädeins the pinch 14 in the headband 23 are the free ends 25, 26 of the legs 24 each, in a slightly different manner, outwardly bent ^¬ .

In order to obtain a secure clamping action of the retaining bracket at the injury through research is at least one, here, the rear legs 24a of the two legs 24a, 24b curled by having a dent 27 inwardly, so that the 's ^¬ kel 24a a spring effect on the Squeezing. The second, front leg 24b is substantially straight, except for the protruding end 25. Thus, the crushing Schung 14 between the two legs 24a and 24b clamped.

At a straight section of a leg, here on the front ^¬ whose legs 24b sits approximately laterally projecting, transversely to the plane of the U of the retaining bracket, a short link ^¬ piece 28, which passes over to a wing part 29th The wing ^¬ part 29 itself has in principle again the function ei ^¬ nes retaining clip, but this time for a stiffened So ^¬ ckelkontakt or base pin 30, which establishes contact with the base 5.

The wing part 29 is ges ^¬ taltet as asymmetric headband. It has a first massive leg 31, which serves as a guide for the socket pin and is equipped for this purpose with guide means. The massive leg 31 runs approximately parallel to the straight leg 24b of the retaining clip in a plane. But its width is about twice as large, its length about the same size as the be ^¬ neighboring straight leg 24b. At one end of the solid leg 31, the guide means are shaped in the form of two ribs 32, which are arched away from the pinch 14 and run parallel to the axis and provide a valley 33 therebetween. This recess 33 serves to fix the socket pin 30. A second leg 34 of the wing part is smaller than the massive leg 31 and ensures the electrical contact of the wing ^¬ part to the base pin 30, its function is that of a Kontaktierungsschenkels. For this purpose, its upper end 35 is angled inward towards the socket pin in order to achieve a secure spring action here as well, the pin 30 being clamped between the two legs 31 and 34 of the wing part 29. The thighs unequal are long, approximately face each other and are connected by a clasp 39. The free end 35 of the second leg 34 is recessed semicircular in order to further improve the positive fit to the base pin 30. The asymmetric headband is completed by a Ver ^¬ binding part, the clasp 39, which connects the two legs 31 and 34.

This connecting part 36 is designed as a base part of a U, but aligned axially parallel and extends laterally only over a fraction of the length of the two legs 31 and 34. It sits relative to the whole mounting clip on the outside of the sides of the legs 31 and 34 at. The base pin 30 is inserted by clamping between the two legs 31 and 34 from below. For better guidance of the base pin 30, two warts 37 are additionally attached at the level of the free end 35 on the solid leg 31. Overall, the mounting clip 20 then sits on the pinch that the first bracket 23 clasps the pinch and also bears laterally inside the bead 17 of the pinch. The asymmetrical holding ^¬ bow or wing part 29 lies 16 with its massive leg 31 on to one of the broad sides ^¬, wherein the associated base pin 30 protrudes high ^¬ this wide side 16 and is contacted by the blade member.

The assembly is done so that the two clips 20 are pushed onto the pinch 14 of the recessed lamp. Thereafter, a welded joint between the external power supply 13 and the associated contact plate 21 is performed. In this case a purely mechanical contact is sufficient, but the welding is safer and easier, otherwise the contact plate would have to be made correspondingly more complicated.

Then, the construction unit of built-in lamp 2 and the two mounting clips 20 is added from above on a plate base 39, which is itself equipped with two socket pins 30 which protrude from the top plate and bottom. This ^¬ at the header pins 30 are unusually entiert so ^¬ ori in the circular base, so that they are in parallel to the lamp axis A, but the side guides to the plane of the external current supply 13 of the integral lamp are staggered. They are ge ^¬ rade arranged so that they protrude outside the pinch seal 14 from the circular base on each side of the pinch and accurately in the ready rack ^¬ te from the mounting clip 20 recording which is realized by the design of the wing piece 29 fit. The Kontaktierungsschenkel 34 of the wing portion 29 thereby clings into the base pin 30 a. Figures 5 and 6 illustrate this unusual orientation.

In a further embodiment of a built-in lamp with a mounting clip 40 according to Figure 7 to 11, the first bracket 41 is similar to the first Ausführungsbei ^¬ game designed. However, in the region of the contact plate 42, the first retaining clip 41 additionally has a Einfä ^¬ delhilfe for the external power supply 13, for example, a slope or, as shown, an obliquely running recess 43, in the region of the angled portion to the base 44. Another difference is that the base part 44 is widened relative to the width of the two legs 45, 46 and that the two legs each have a base portion 44 facing broadened pedestal 47 adjacent to the lowermost part of the leg, the width the base part 44 is adapted. The two legs 45, 46 have only about half of the width of the base part 44. They stand up terminally on the base part, so that the pedestal 47 causes a one-sided extension of the width of the legs. The legs 45, 46 themselves, as far as their lateral extent is concerned, are still slightly over on the outside, even beyond the base part, see point P in FIG. 9. The meaning of this construction is that the pedestal 47 is thus under the bulge 17 of the pinch, which serves as a stop, can be pushed laterally from the inside. The bead 17 provides an even better defined stop plane than is the underside of the pinch ^¬ Schung in the first embodiment.

The wing portion 48 is here, however, designed fundamentally different than in the first embodiment. The massive leg, which serves to guide the socket pin 30 is here substantially as U-shaped or better as shown formed as a rounded trough-shaped rail 49, which is arranged axially parallel, and via a short connector 50 with the second straight leg 46 of first retaining clip is connected. The guiding means of this massive first leg are here the side walls of the trough. The end of the header pins 30 fit in precisely into the trough from NEN was ^¬ dimensions.

The second leg 51, which is equipped as a Kontaktierungsschenkel with spring properties, is cut out of the wall of the trough, which is opposite to the connecting piece 50. This second wall 52 of the trough is only rudimentary and has only a first portion 55 with a length of about 20% of the length of the first wall 53, directly on the connector attaches. This first section sits at the top of the trough 49, towards the built-in lamp.

The Kontaktierungsschenkel 51 is corrugated similar to the first embodiment. However, he sits 90 ° turned to the base 54 of the trough. So he pushes the socket ^¬ pin 30 in the direction of the opposite first wall of the trough. The Kontaktierungsschenkel 51 has a base 56, which serves as a second portion of the second wall of the trough at the same time, and a free corrugated tongue 57, with its end 58 inwardly toward the Sockelpin out. This tongue is a spring tab that ensures the mechanical and electrical contact with the socket pin. For better contact with the base pin, this tongue has a lateral quarter-circle-shaped recess 59 at its end 58.

As long as the mounting clip 40 is not installed, be ^¬ preferably the tongue is so strongly wavy (and the spring action pronounced) that they can reach with its end 58 to the opposite first wall of the trough. For this reason, a window 60 is preferably mounted in the region of the first wall 53 of the trough, in which the free end 58 of the tongue 57 protrudes, as long as the base pin is not inserted into the trough. In addition, the trough has at its lower end a slightly outwardly projecting collar 61, which serves as a threading aid for the socket pin.

The mounting of this clip 40 is similar to the ers ^¬ th embodiment described.

It is important for both embodiments of the mounting clips that they have a retaining clip which prevents the binding The mounting bracket further comprises a wing part, which allows contacting a separately arranged base supply line, the free end outside the plane of the outer current ^¬ feeds is arranged. The base pins are preferably fixed by a Tellerfuß. They protrude laterally next to the bruise from the base of the plate or similar. The wing part has a solid guide part and a resilient contacting part, which presses the socket pin into the guide part and securely contacts it electrically. It can be dispensed so ^¬ even on a welded joint.

The invention is an electric incandescent lamp geschaf- fen, which is inexpensive to manufacture and can replace ^¬ conven tional, energy-consuming light bulbs. In addition, the invention can also be used in discharge lamps such as compact high pressure discharge lamps.
