Definitions
- the invention relates to a centering element for centering an electrical lighting means, such as a tubular lamp or a tubular radiator, in a cladding tube, and a mounting for an electrical lighting means which has at least one of these centering elements.
- Tubular illuminants are often arranged in a transparent jacket tube, the inner diameter of which is greater than that of the lamp or the radiator, in order to protect the lamp surface and possibly also the terminal electrical contacts from contact and contamination, etc.
- lamps are understood to mean illuminants, the main purpose of which is to illuminate with light in the visible wavelength spectrum, while radiators also include all UV and IR radiation sources that are used technically for photochemical reactions, disinfection, etc.
- UV lamps can be used in the following; However, other light sources such as UV lamps should always be understood in the corresponding context.
- the arrangement of the illuminant in the cladding tube can, depending on the length and diameter, be associated with difficulties, so that the cladding tube can be scratched if it is not inserted exactly axially through the lamp ends.
- not only axial insertion is desirable, but also a centered arrangement of the illuminant in the cladding tube in order to achieve uniform illumination or irradiation of the surroundings surrounding the cladding tube.
- the centering element has an axial opening through which the elongated inner electrode runs and extends essentially from the inner electrode to the inside of the outer tube, so that the inner electrode is centered in the outer tube, the diameter of the centering element being smaller than the inner diameter of the Outer tube, to prevent jamming.
- Its wall has parts which are formed radially in the direction of the inner electrode to support the centering element against axial slipping.
- U.S. 3,249,781 A describes a lamp holder with a centering element for centering holding a lamp in a cladding tube.
- the centering element the area of which is smaller than the cross section of the cladding tube, has an axially central bore and elastic spring elements which extend in sections on an outer circumference of the centering element and provide a radial restoring force.
- the object of the invention is to provide a centering element by means of which a light source, in particular a tubular light source, can be axially inserted into a smooth-walled cladding tube and axially centered without the inside wall of the cladding tube being scratched or otherwise damaged.
- a centering element according to the invention which is provided for centering a lamp in a cladding tube, has a disc base body with an axially central bore for receiving the lamp, the diameter of the disc base body being smaller than an inside diameter of the cladding tube.
- the disk base body can have further bores which are arranged specifically for use.
- a disk base body is understood to mean a cylindrical body, the radius of which is many times greater than its thickness.
- a disk base body of a centering disk according to the invention can, however, similar to a hub, have a base section around the axially central bore, which is offset from the disk section and can be manufactured in one piece with it.
- the type of illuminant that is inserted and placed in a cladding tube with a centering disk according to the invention can is in no way restricted here; both lamps and emitters such as fluorescent tubes, dielectrically hindered discharge lamps, high, medium and low pressure lamps as well as LED lamps, excimer lamps, incandescent lamps, induction lamps, sodium vapor lamps, halogen lamps, metal halide lamps, sodium vapor lamps, laser lamps, energy-saving lamps and HID lamps in general, in which a large number of LEDs are arranged on a holding and / or cooling body, can be inserted axially centered into a cladding tube by a centering element according to the invention and positioned there.
- lamps and emitters such as fluorescent tubes, dielectrically hindered discharge lamps, high, medium and low pressure lamps as well as LED lamps, excimer lamps, incandescent lamps, induction lamps, sodium vapor lamps, halogen lamps, metal halide lamps, sodium vapor lamps, laser lamps, energy-saving lamps and HID
- the centering element has at least one elastic spring element that extends at least in sections or all around extends the outer circumference of the disc base body and provides a radial restoring force.
- the elastic spring element When inserted into the cladding tube, the elastic spring element is compressed radially against its restoring force and thus ensures a uniform circumferential spacing of the centering element and thus the illuminant received by it from the inner wall of the cladding tube.
- the elastic spring element enables the centering element to slide along the inner wall of the cladding tube and, through the restoring force, ensures a certain axial hold in the cladding tube in the desired position.
- a tubular illuminant can be conveniently, safely and simply placed precisely in a cladding tube without damaging the cladding tube on the inside, which would be disadvantageous for uniform radiation exit and operational reliability, apart from the visual and aesthetic impairment.
- the centering element enables tool-free assembly of the illuminant in the cladding tube and also prevents assembly errors. Forces that act on the lamp base in the event of angular misalignment and vibrations can be compensated for by the spring element.
- the spring element extends circumferentially around the disk base body;
- several spring elements can also be evenly distributed around the circumference of the disk base body - although two spring elements, which are arranged at opposite points on the circumference, can in principle be sufficient for this purpose;
- three or more spring elements evenly distributed around the circumference are desirable.
- a spring element which extends around the entire circumference, is provided by a resilient wire winding, the wire being guided through a plurality of axially parallel openings on the edge of the disk base body, thus forming a worm spring, i. H. resemble a coil spring bent into a circle.
- Alternative spring elements are individual spring bodies made of wire, which are attached to the circumference or are likewise guided through axially parallel openings on the edge of the disk base body and are thus attached.
- the wire for the wire winding or the spring body can be a flat or round wire.
- round wire can be preferred because of the torsion that occurs in the wire and also because it is easier to manufacture than flat wire.
- the diameter and opening profile of the axially parallel openings can be designed according to the diameter and profile of the wire selected for the spring element; simple circular bores are sufficient for round wire.
- flat wire may be more advantageous, depending on the design of the spring body, since it is held in a rotationally fixed manner in a corresponding slot-shaped opening so that the individual spring body cannot escape when it is inserted into the cladding tube.
- individual rings made of flat wire which are arranged distributed over the circumference of the disk base body, are then also conceivable as the spring body.
- the wire material used is metal or, depending on the type of light source, also a correspondingly temperature-stable and optionally UV-stable plastic.
- a circumferential or sectional foam layer is also provided as the elastic spring element, which foam layer can be attached to the edge of the disk body, for example by gluing.
- the foam material used which can be formed by foamed plastic, is to be selected to be light- or UV- and / or heat-resistant according to the type of light-emitting means to be centered with the centering element.
- the elastic spring element has a certain relative to the inner diameter of the cladding tube Excess in order to be able to exert a corresponding pressure on the inner wall of the cladding tube during insertion and placement.
- the pressure exerted on the inner wall of the cladding tube by the radial restoring force can be predetermined and thus fixed.
- the axially central bore of a centering element according to the invention can be designed directly to receive a light source and, for this purpose, may have structures such as form-fit elements, a thread or latching elements.
- connection element for the lighting means is provided in the axially central bore, since this achieves greater variability in that different connection elements can be used depending on the lighting means.
- the connection element can be in one or more parts and is detachably fastened to the disk base body, for example by means of a plug-in or screw solution.
- the connection element preferably forms a fastening and contact device for the detachable mechanical fastening and for the detachable electrical contacting of the base of the illuminant on the centering element.
- the disc base body of the centering element has at least one eccentric bore for mounting purposes, which is designed directly for the detachable attachment of a rod and can optionally have structures such as form-fit elements, a thread or latching elements for this purpose.
- the eccentric bore (s) can accommodate a connection element for the linkage, which can be made up of one or more parts and is detachably fastened to the disk base body, for example by plugging or screwing.
- connection element not only ensures a releasable mechanical fastening of the linkage to the centering element, but at the same time also provides a releasable electrical contact when the linkage, in addition to the holder, simultaneously fulfills the task of the electrical supply line.
- an electrical bridge element for example wire bridges made of metal strands or metal strips, can be arranged between the connection element of the eccentric bore and the connection element of the axially central bore.
- electrical contact can be established, for example, by means of applied conductor tracks.
- the disk base body can be made of a metallic material, for example a stainless steel; however, a ceramic material can advantageously be used, since it has a high dielectric strength.
- a lamp holder according to the invention has at least one centering element according to the invention.
- the centering element supports the introduction and precise positioning of a lamp in a cladding tube, so that the lamp is always axially central in the cladding tube.

- an insulator sleeve 91 which can be made of glass, for example.
- connection elements can also be established in a variant that deviates from the way shown here by way of example. Electrical contacting means for this purpose are known to the person skilled in the art.
- FIG. 8 Next is in Fig. 8 to see how the centering element 8 rests in the cladding tube 10 through the somewhat radially compressed elastic spring element 3 and thus ensures the centered arrangement of the illuminant 100.
- the centering element 1 With uncompressed elastic spring element 3 the centering element 1 has a certain oversize compared to the inside diameter of the cladding tube 10.
- the disk base body 2, the diameter of which is smaller than the inside diameter of the cladding tube 10, is circumferentially spaced uniformly from the inner wall of the cladding tube 10 by the elastic spring element 3.
- centering element 1 allows axial displacement, thermal expansion effects can also be compensated, so that no stresses occur in the holder 9, the illuminant 100 and the cladding tube 10.
- the cladding tubes suitably have a circular cross-section, and therefore the centering element also has a circular disk base body.
- a lamp is to be arranged in a cladding tube with a non-circular, for example polygonal, cross-section, so that the disk base body will have a corresponding shape and correspondingly smaller dimensions to allow the elastic spring element on the inner wall of the shaped Cladding tube.
- a layer 3 ′′ of foam material can circumferentially surround the disk base body 2 of the centering element 1 as an elastic spring element, as in FIG Fig. 9 is shown.
- the disk base body 2 does not have a stepped edge section.
- the elastic spring element can also be a foam material layer in the case of a disk base body with a stepped edge section.
- the disk base body 2 with foam material layer 3 ′′ as an elastic spring element can also have eccentric bores for receiving a linkage and / or recesses for weight reduction in addition to the axially central bore 4.
- Whether a layer of foam material can be used as the elastic spring element depends on the type of light source, i. H. its emission spectrum and operating temperature, which is centered and maintained with the centering element.
- Suitable high-temperature and UV-stable plastics can, for example, polyetherimide, various fluoropolymers such.
- plastics whose operating temperature is well above 200 ° C are, for example, polyether ketone, polyether ether ketone and polyether sulfone, but they are not resistant to UV radiation.
- UV stabilizers in such plastics may be considered. Suitable plastics must also be foamable.
- the foam material can be attached, for example, by gluing, with the adhesive material also having to meet the requirements with regard to temperature and UV resistance.
- a foam material made of plastic can be sprayed on or drawn on.
- the disk base body can also have circumferential form-locking elements, e.g. B. a circumferential groove.
- Fig. 10 shows a representation of two further variants of elastic spring elements for centering elements 1 according to the invention.
- a full-circumferential foam material layer 3 ′′ which is shown in FIG Fig. 9 is shown, it can also be provided that the foam material layer 3 ′′ is only present in sections distributed over the circumference of the disk base body 2.
- Fig. 10 shows individual spring washers 3 ′ made of a flat wire or strip material, which are evenly distributed around the circumference of the disk base body 2.
- the spring rings 3 ′ can be accommodated in correspondingly slot-shaped recesses of the disk base body 2 close to the edge. It is not absolutely necessary for the recesses to be continuous and for the spring washers 3 'to be closed. It is just as well conceivable that a spring ring 3 'is perforated at one point.
- the ring instead of through a continuous slot with both ring ends, the ring can engage in corresponding recesses on both sides of the disk base body 2, so that the spring ring 3 ′ clamps on the disk base body 2.
- Round wire is less suitable for spring washers of this type, since they can give way in the event of radial loading if they are only received in a correspondingly round recess in the disk base body.
- wire winding or the spring washers over other forms of a spring element made of metal wire is that scratches are avoided or greatly minimized by the rounded contact surface of the springs on the glass of the cladding tube.
- these spring elements allow shielding gas to pass between the disk body and the cladding tube, if shielding gas is provided for the illuminant in the cladding tube.
- the permeability for protective gas is improved by the openings, which are also provided for weight reduction.
- the spring element enables tolerance compensation in the cladding tubes, in particular in the case of attachment points, out-of-roundness and changes in wall thickness, so that the centering element, which holds the illuminant and centers it in the cladding tube, is always in contact. Any vibrations that may occur are dampened by the spring element, which also allows the centering element to slide in the event of thermal expansion of the linkage in the cladding tube.
- the preferred centering element with a disc base body made of ceramic and a spring element made of metal, which is stable even at very high temperatures, there is also no outgassing of foreign substances that could react or lead to contamination.
