Definitions

the invention relates to a single-capped lamp according to the preamble of claim 1.
These are in particular high-pressure discharge lamps, preferably metal halide lamps, but also, for example, halogen incandescent lamps.
an elongate, in particular ceramic, discharge vessel is used as lamp bulb.
a single-ended lamp which is composed of three pistons. It has a ceramic adapter, which is mounted on a screw base. There is atmospheric pressure between the outer bulb and the outer bulb.
the EP 1 109 199 describes a single-capped high-pressure lamp in which the outer bulb is surrounded by a reflector.
the base is attached by crimping directly to the reflector neck.
the disadvantage of this is that the dimension of the neck of the reflector must be matched to the standard dimensions of the base.
modularly produced lamps in particular high-pressure discharge lamps, advantageously require those having a ceramic discharge vessel, a damping element. It is used between outer bulb and base ceramic, so that in the specific manufacturing processes no glass breakage can occur.
a damping element according to WO2005015605 a commercial O-ring used.
the single-ended lamp has a vacuum-sealed lamp bulb, in particular an elongated discharge vessel, which may still be accommodated in an outer bulb, wherein the lamp bulb, ie the discharge vessel or the discharge tube assembly with outer bulb, is still surrounded by a Hüllteil.
a ceramic discharge vessel in particular for a metal halide lamp, for example for general lighting purposes.
the electrical connections are normally connected to power supply lines, which produce an electrical contact to a light source inside the lamp bulb, for example, the light source is realized by electrodes or a luminous element of an incandescent lamp.
external electrodes may also be used, or an electrodeless configuration.
a discharge vessel made of quartz glass or hard glass can also be used.
An outer bulb is not essential.
the sheath part is fastened by a bracket part bridging the distance between the lower plateau of the base stone and at least the upper contact surface of the edge.
the enveloping part and the clamp part form a unit, wherein the holder of the enveloping part is realized in the upper part of the base brick, for example by crimping.
the base has, in addition to the base stone on a conventional, the socket facing part, for example, a screw base approach or bayonet socket approach.
the lamp bulb so for example, the outer bulb or the discharge vessel in the absence of an outer bulb, held in the central opening by means of a spring clip.
This technique is known in principle, see for example DE 198 56 871 ,
edge of the Hüllteils and the segment of the base stone is equipped with a cooperating Verfitschutzmechanismus.
the clamp part consists of circumferentially distributed brackets or a circumferential clamp tape.
the staple band is a deformable ring, which is made in particular of metal or plastic, so that a very simple holder is made possible by the fact that the staple band is already angled at the lower edge, and it is raised to the stop over the base stone to the projecting segment.
the ring preferably made of aluminum, can be mechanically formed on the segment, and thus fix the edge of the Hüllteils.
the prior art is that between the clamp part and the upper contact surface of the edge of the Hüllteils a damping means is introduced. It is in particular a kind of O-ring, for example made of an elastomer.
the material of the Hüllteils preferably glass or aluminum, protected during the Anformreaes from damage.
the damping element is made in one piece from temperature-resistant, preferably elastic, plastic.
the damping element is made in one piece from temperature-resistant, preferably elastic, plastic.
two main functions are realized simultaneously.
damping is achieved when connecting outer bulb and base ceramic, as is known.
the damping element is designed as a ring, in which extends at least one web shoulder at two opposite points within the ring.
the web extension is designed as a continuous web extending between the two web extensions. However, it can also be interrupted in the middle, so that there are two separate web approaches.
the web or the web approaches can guide holes, in particular for the power supply of the base lamp or similar.
the ring may preferably be a or a plurality of recesses, such as a locking groove, to ensure a desired orientation of the damping element with proper alignment of the web approaches.
the lamp then has a corresponding counterpart, for example in the field of base ceramic.
the ring may also consist of two parts, preferably symmetrical halves, which do not have to be connected to each other and which also do not have to give a complete ring.
the manufacturing process is carried out as follows:
the damping element (1) is placed on the plateau of the base ceramic (2).
two fracture-sensitive materials namely the glass outer bulb (3) and the base ceramic (2) are mechanically connected by means of an aluminum ring (4).
the base ceramic is preferably made of steatite. Between the two materials is located to prevent breakage, preferably one-piece damping element (1).
the previously used O-ring also achieves damping and prevents breakage. However, due to its shape, this is not necessarily stable in terms of location. That he could, either during assembly or when screwing the finished lamp in the socket slip. Piston misalignment or a loose piston would be the result. This can no longer occur in the case of a one-piece, flat damping element (1).
the web approach is pulled so far inward that it simultaneously ensures damping when joining a base lamp in a base ceramic.
the damping element (1) is placed on the plateau of the base ceramic (2).
a base lamp (7) provided with a clip (6) is inserted into the shaft (8) of the base ceramic (2) by means of a suitable device.
the device works with a firm stop.
the total length of the base lamp varies due to the existing tolerance, the z. Gr. Part is determined by the down freely expiring Quetschungsunterkante (9).
the fixed stop of the joining device is set once with the aid of existing base lamps.
the bottom edge of the base lamp squeezing must be joined as close as possible to the plateau (2) of the base ceramic, but must not come in contact with the base ceramic, as this carries a high risk of cracks and flaking.
the pinch bottom edge (9) would be pressed onto the plateau of the base ceramic.
the device has a spring element for this case. However, the force required for the joining process can still damage the pinch.
damping element (1) prevents this largely.
Suitable materials for the damping element in particular Teflon or silicone rubber VMQ or Viton FPM in question.
the thickness of the damping element should preferably be between 0.5 and 1.5 mm, including boundary values.
One advantage is that the connecting force between the enveloping part and the segment remains free of play due to the damping element over the life of the lamp. Due to the damping ring, the tension of the clamp part can be safe be increased and thus the connection made more reliable.
the base also has a barrel-facing part, which is at least partially connected as known per se by crimping with the base brick.
this part contains a standard screw thread.
the enveloping part may, for example, be a closed part such as another, but not vacuum-sealed, outer bulb, or else a calotte, which has a reflector contour.
a typical application is a metal halide lamp with a ceramic discharge vessel, which contains a filling with or without mercury content, optionally with inert starting gas, preferably noble gas.
FIG. 1 and 2 An embodiment of a metal halide lamp 10 shows Fig. 1 and 2 in an exploded view and assembled.
a ceramic discharge vessel 9, which is closed on two sides, is arranged longitudinally in the lamp axis A and surrounded by a wide enveloping bulb 3.
the discharge vessel 9 is closely surrounded by an outer bulb 7, which is crimped on one side and made of tempered glass.
a frame 4 with short and long supply line holds the discharge vessel 9 in the outer bulb 7.
the electrodes in the interior of the discharge vessel are connected via feedthroughs with the supply lines. The latter are in the region of a pinch seal 6, which closes the outer bulb 3, connected to external power supply lines 11.
the pinch 6 of the outer bulb is seated in a matching opening 8 of a base 12 made of ceramic and is optionally held there by a metal clip, as known per se (not shown).
This opening 8 is surrounded by a central collar part 13. It protrudes from a plane which forms the upper plateau 14 of a radially projecting disc-shaped segment 15. It sits on a neck part, which holds a framed assigned part, here a screw base part 19 threaded.
the neck part is hollow inside, wherein the power supply lines 11 are connected to electrical terminals 21 of the base 23 of the neck portion.
the enveloping piston 3 is equipped at its opening 25 with a radially projecting edge 27. It has a flat lower contact surface, which is adapted to the upper plateau of the segment of the base stone.
the upper plateau may have bumps which cause a spacing of the upper plateau to the enveloping piston.
it has a narrow upper contact surface, which is parallel to the lower contact surface or obliquely aligned.
An elastomer ring for example made of Viton®, may be placed on it, see below WO 2005015605 ,
FIG. 5 a further embodiment of a damping element 1 is shown. In him no continuous web is provided, but an extended stub stump 40 each on the web shoulder, each stump still has the holes 32.
Fig. 6 shows an embodiment of a damping element 1, in which only a very short stub stump 41 is used without holes.
FIG. 7 shows a further embodiment of a damping element 1, in which a continuous web 31st is used, wherein a guide groove 45 is attached to the outside of the ring outside, in the amount of one of the web approaches, because here enough meat for the recess of the guide groove is present.
the guide groove can engage in a nose 46 of the base, see FIG. 2 ,
the annulus has no constant width B, but two more recesses.
FIG. 8 finally shows a damping element 50 which is composed of two parts 51. Each part is a short semi-ring, each having a web extension 30 and a stub stump 31.
the damping element is generally a disc cut out of a disc having a given width B that is appreciably greater than the thickness D (see FIG FIG. 2 ) of the disc, so that a position stabilization is achieved.
a typical value of the width B is 2.5 mm with a typical thickness of 1 mm.
a typical value range for B is 2 to 4 mm, a typical value range for D is 0.5 to 1.5 mm.
the ratio B: D is at least 2: 1. It can be up to 8: 1 and possibly even higher. Of course, this condition is still met if in parts the width B is made smaller on the damping element, since it depends only on the stabilization.
the damping element is of course also with reflector lamps or similar. applicable, see W02005015605 , In this case, the envelope part is the reflector.
