Technical area

The invention relates to a lamp according to the preamble of claim 1. The invention relates in particular to an electric lamp consisting of a built-in an outer bulb integral lamp and a base, wherein the base is electrically connected to power supply wires of the built-in lamp. The invention further relates to a single-ended electric lamp with a salient Erten in a socket outer bulb and at least one arranged within the outer bulb integral lamp. Such halogen incandescent lamps are intended in particular for operation on high voltage (HV) with typically 100 to 250 volts.

State of the art

The DE-A 10 2005 051 076 discloses a holder for a 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 base plate of the outer bulb, which is very expensive, since the glass foot is a very complex component, which includes, for example, exhaust tube and melted supply wires.

Presentation of the invention

The object of the present invention is to allow mounting of a built-in lamp on a plate base with the shortest possible length.

This object is achieved by the characterizing features of claim 1.

Particularly advantageous embodiments can be found in the dependent claims.

The invention ensures the simple production of a lamp, consisting of a built-in lamp, a base and an outer bulb. The invention provides a single-ended electric lamp with an outer bulb fastened to a base and an integral lamp disposed inside the outer bulb, 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.

The integral lamp consists essentially of a hermetically sealed lamp vessel, at least one lamp and a power supply system for the lamp, which generally has two outer power supply lines, which protrude from a pinch of the integral lamp axis parallel. The light source is usually a luminous element, 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. It is connected via internal power supply lines and possibly foils to the external power supply lines.

The power supply system connects the lamp arranged in the interior of the lamp vessel with a lamp arranged outside the 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 wires of the external power supply lines. The built-in lamp is usually filled with an inert gas and a halogen additive. Instead of an incandescent lamp but can also be used as a built-in lamp, a high-pressure discharge lamp, similar to in DE-A 32 32 207 described.

The joke of the invention is that a high compactification is achieved in that the external power supply of the built-in lamp are not connected as usual now 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 built-in lamp ends up as angled wires. The mounting clip preferably contacts a wire via a contact part.

The mounting clip also has a hollow rail, which is connected via a frame part with the contact part. This hollow rail is connected by a clip connection with a socket pin or socket contact brought up from the socket, which protrudes upwards from a disc base.

Essential for the shortening of the overall length 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 components a contact surface for the external power supply to the contact part, acting as a connection frame member and a hollow rail, which is connected to the contact part via the frame part.

The frame part is designed in its basic design as an L-shaped bent sheet metal part, wherein the first side of the L ends at the hollow rail. The second side of the L is bent at substantially right angles thereto and preferably carries the contact surface for the power supply. The shape of the L is adapted to a broad side and a narrow side of the pinch of the integral lamp.

Preferably, the first side of the frame part is at least as long that it corresponds to half the width of the broad side of the pinch of the integral lamp. The second side of the L is preferably dimensioned so that it corresponds substantially to the width of the narrow side of the pinch of the integral lamp. Preference is given to the pinch according to the known H-, double-T or I-shape with widened narrow sides that project bead-like equipped.

Preferably, one or both sides of the L are designed in the manner of a window frame, that is essentially a quadrangle, which is recessed inside for saving material. The square is not necessarily planar, but it can be curled to improve the stability or be adapted to the shape of the H or I of the pinch.

In this case, the contact part is essentially preferably an extension of the frame part, essentially pointing downwards, preferably angled slightly inwards. Preferably, the contact part sits as a tab on the second side. Down here means pointing from the bruise to the pedestal.

Preferably, the external power supply of the built-in lamp is bent outward so that it rests on the inside of the contact part.

The hollow rail runs axially parallel to the built-in lamp. It sits at an end portion of the first side of the mounting clip. It is U-shaped in cross-section with two legs and an intermediate base part and is integral with a first leg of the U on the first side of the frame part. In this case, this first leg is angled approximately at right angles out of the plane of the frame part. The hollow rail is adapted so that it closely surrounds the base contact, which protrudes from a Tellerfuß upwards to the built-in lamp.

To fix the hollow rail in the region of the second leg, which is free to be broken, so that a clamping piece is dissolved out of the meat of the second free leg, which can be inclined inwardly against the socket contact and thus pressed against the socket contact.

In a preferred embodiment, the frame part ends here on the second free leg. It is not excluded that it is extended beyond the hollow rail addition. The frame part lies substantially at least on one broad side and a narrow side of the pinch.

In a preferred embodiment, the frame part is further extended, so that it completely surrounds the narrow side and also extends to a part of the second, the first opposite broad side. In this case, the basic form is extended from an L to a modified U with legs of different lengths. This third side, preferably as a short leg of this modified U, is bent back from the narrow side to the second broad side. Preferably, this third side of the frame facing the second broad side has a spring tab. It is preferably bent back at its free end, so that it rests with this protruding end on a knob, which protrudes from the pinch. The third side may be strip-shaped, with the spring tab attaching to one end of the strip like a gallows.

Preferably also sits on the second side of the frame part also at least one spring tab which is directed against the associated narrow side of the pinch This spring tabs provide a clamping stop of the mounting clip on the pinch. The electrical contact between the power supply and the contact element is preferably ensured or improved by welding. The same applies to the connection between base contact and hollow rail.

Particularly preferred two identical mounting clips are used, each connecting a socket contact with an external power supply. The clips are added to the pinch of the built-in lamp. Spring clips fix and hold the clip in the correct position at the pinch of the built-in lamp. A spring tab snaps into a nub of the broad side of the pinch. The U-shaped or curved bent back, preferably bent slightly outwardly power supply of the integral lamp contact the contact element of the clip, preferably in the direction of the narrow side of the pinch towards. The assembly clips with built-in lamp is then added to the base contacts of the plate base. However, the plate foot as such is not absolutely necessary in this form. It can also be replaced by a similar effect other fixing means for the socket contacts.

Preferred embodiment of the invention

Figure 1 to 3 shows a lamp 1 according to the invention. FIG. 1 represents the lamp in an exploded view. In a base 5 of the commercial type E27, an outer bulb 6 type A55 is held. Within the outer bulb 6, a built-in lamp 2 is arranged so that a luminous body 3 of the built-in lamp 2 is approximately at the point within the outer bulb 6, to which also the filament is arranged in a conventional incandescent lamp. 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 built-in lamp 2 has a longitudinal axis A and is mechanically connected to a Tellerfuß 4, protrude from the pin-like socket contacts 4a, 4b. These are connected to the actual base leads 44a, 44b.

The built-in lamp 2 is, for example, a one-sided pinched halogen incandescent lamp with 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 consists of connected to the filament 3 inner power supply wires 11, fusing films 12 and outer power supply wires 13, which are laterally bent back approximately U-shaped. The ends of the inner power supply wires 11 facing away from the luminous element 3, the sealing films 12 and the sealing films facing ends of the outer power supply wires 13 are in a pinch 14, which closes the lamp vessel 10, melted. The pinch 14 is preferably executed in so-called. Double T-shape, with two narrow sides 18 and two broad sides 19 and with a protruding bead 17 on the side edges of the narrow sides.

The lamp vessel 10 is filled with an inert gas and halogen additive. At its opposite end of the pinch 14, the lamp vessel 10 is melted. The lamp vessel 10 is hermetically sealed to the outside.

The built-in lamp 2 is held by two mounting clips 20, see FIGS. 3 to 5 , The two mounting clips 20 are preferably identical, but need not necessarily be. Each has a contact surface 21 for the external power supply 13, which is formed substantially as a tab.

Each clip 20 consists of a sheet metal strip which is bent substantially U-shaped. He has a first side 22 which is arranged approximately parallel to a first broad side 19 of the pinch, a second side 23 which extends approximately parallel to a narrow side 18 of the pinch, and a third side 24, which in turn is approximately parallel to second broad side 19 of the pinch is arranged. The first page 22 can be seen from above ( FIG. 4a ) are considered as the first long leg of a U. The third side 24 is the second short leg of U. The second side 23 is the base of the U.

The free end of the first leg is formed into a hollow rail 30, which is U-shaped in cross-section is. The first side wall 31 of the hollow rail is angled directly at approximately 90 ° to a frame part 15 of the first side 22 attached. This is a roof wall 32 is set, which is arranged approximately parallel to the frame part 15. This is the second side wall 33, which is bent back towards the plane of the frame part. The hollow rail 30 may also be continuously curved, so that a smooth transition between side walls and roof wall is present. The hollow rail 30 has a skirt-like expanded threading 29 at its lower end.

In the embodiment shown, the second side wall 33 and partially the roof wall 32 is incomplete. Approximately in the middle of a larger recess 40 is provided, from which a clamping member 34 projects obliquely into the channel formed by the hollow rail 30. The purpose of the clamping part 34 is the provisional mounting of the inserted into the channel of the hollow rail base contact 4a and 4b.

The mounting clip 20 also has on its second side 23, a second frame part 36, in which it arrives above all on two spring parts 37. The second frame part 36 here has two transverse struts 39 and 40. The spring tabs 37 sit on the upper transverse strut 39 at the lower edge and extend transversely thereto, so that they can exert pressure on the narrow side of the pinch and thus fix the clip 20.

The clip 20 also has on its third side 24 a detent spring 28 which presses against the second broad side 19 of the pinch and there with a projecting nub 27, see FIG. 6 , cooperates so that they fixation and adjustment of the clip 20 together with the Improved spring parts 37. In this way, a reliable connection of the unit built-in lamp plus clip 20 can create, which can then be plugged onto the plate base 4 with the base pins 4a, 4b. The base pins are inserted into the hollow rails 30 and welded there, preferably by laser welding.

The third side 24 has, in principle, an axially parallel strip 51, at the first end of which the detent spring 28 is attached in the shape of a gallows. At its second end, a projection 52 is laterally bent, so that the projection on the pinch embraces the bead 17.

The first side 22 is corrugated so that the bead 17 of the pinch is enclosed by it and can be enclosed by the hollow rail 30 in approximately the middle of the broad side of the pinch of the socket contact lying in front 4a.

In a further embodiment according to FIG. 7 on the left, the mounting clip 50 is in principle similar to the first embodiment. However, this is dispensed with the third side, so that the clip is bent only L-shaped from the first side wall 22 and the second side wall 23. The contact plate 55 sits here on the first side wall 22. Accordingly, then the external power supply 13 in this direction must be bent. In the background, a three-part clip 20 is shown as described above.

The mounting of such clips is done so that the two clips 20 are joined to the pinch of the recessed lamp, with spring tabs and locking springs secure the fixation and exact adjustment. Here are the U-shaped bent outer power supply of the integral lamp to the contact plate 21 at. This assembly is then added to the pedestal contacts 4a and 4b protruding from the pedestal 4. The base contacts 4a and 4b are thereby fitted into the hollow rail 30 and possibly provisionally supported by the clamping part 34 there.

A firm connection between the clip 20 and base contact 4a, 4b is achieved by laser welding, resistance welding, etc. in the region of the hollow rail 30. The joining of the base contacts 4a, 4b is facilitated by the inlet slopes 29 as Einfädelhilfe, the same effect centering. This creates a positive and electrically secure connection. Similarly, the connection between the external power supply and the contact surface 21 by means of laser, etc. is welded. Overall, the advantage of this mounting technology is a cheap, stable, precise and space-saving attachment of the recessed lamp in an outer bulb, especially using a Tellerfußeinschmelzung o.ä. Technique that allows fixation of the ends of the socket contacts. This ensures a short overall length of the entire lamp.

Note: The locking springs and spring clips and clamping parts are similar acting parts, but are distinguished conceptually.
