The present invention relates to an insulating glass unit formed from a plurality of transparent layers with the features of independent claim 1, wherein at least one illuminable plate made of transparent material is arranged between at least two mineral glass plates held at a defined distance from each other by means of a spacer element.

A glass unit formed from a plurality of transparent layers, in which an illuminable plate of transparent material is arranged between at least two glass plates which are held at a defined spacing from one another by means of a spacer, can be seen, for example, in EP 2 852 855 B1. There, an LED-illuminated glass insulation panel is disclosed in which two spaced-apart glass substrates are held together and / or spaced apart by a spacing profile, which spacing profile comprises upper-side retaining means for holding an illuminable intermediate substrate and lower-side cooling fins for dissipating heat from the at least one The light source associated with the spacing profile is generated.

In view of this solution known from the prior art, it can be regarded as a primary object of the present invention to provide a multi-layer insulating glass unit with an illuminable sheet of transparent material which is universally constructible and quick and easily modifiable Lighting offers, without about such a change in the lighting, the insulating properties of the entire unit in any way must be affected or impaired.

This object of the invention is achieved with the subject matter of the independent claim. Features of advantageous developments of the invention can be found in the dependent claims.

In order to achieve the stated object, the invention proposes an insulating glass unit formed from a plurality of transparent layers, in which at least one illuminable plate of transparent material is arranged between at least two mineral glass plates held at a defined distance from one another by means of a spacer element. The mentioned glass plates may be commercially available

Mineral glass or normal glass act, but is also the use of example Plastic glass possible. In principle, the use of organic glass or inorganic glass is possible. This illuminable plate is held and / or supported at least on a longitudinal edge of or by the spacer element, optionally there stabilized only in its position, which usually provides a parallel arrangement to the normally also arranged parallel to each other at least two spaced apart mineral glass plates. The spacer element which defines or at least partially defines the distance between the at least two mineral glass plates is formed by at least one hollow profile. Preferably, the at least one hollow profile comprises a plurality of adjacent hollow chambers.

Furthermore, it is provided in the insulating glass unit according to the invention that at least two lateral surfaces of the hollow profile, preferably adjacent to the at least two lateral hollow chambers, each an outer mineral glass plate and / or rests, optionally also on an inserted there additional insulating layer or each arranged there spacer any material such as out

Aluminum, plastic, chromium-nickel steel, so-called TPA, which is a thermoplastic spacer, made of silicone foam, or a combination of several materials. On the middle hollow chamber of the

Distance element or the hollow profile, which is connected by material bridges in each case with the at least two spaced-apart lateral hollow chambers, is the illuminable plate with its longitudinal edge on or on, optionally also on an optionally inserted there insulating layer, which will be described in more detail below should.

In the middle hollow chamber is at least one strip-like or by several juxtaposed or spaced lighting element formed lighting element which illuminates the edge of the illuminable plate in the activated state and / or irradiated in the peripheral edge of the illuminable plate, whereby the insulating glass unit according to the invention the special character of evenly and / or with specifically producible effects illuminable

Insulating glass unit receives. The illuminable plate can be made of organic or

inorganic, mineral glass. When using an illuminable plate made of organic material such as a suitable transparent plastic such as so-called. Acrylic glass or PMMA (polymethylmethacrylate) or other suitable transparent thermoplastic resin, the effect can be used that these plastic materials a refractive behavior for edge-coupled light from a Have illumination source, which differs to a uniform Radiation of the entire plate surface with simultaneous loss of part or loss of transparent properties leads. Also, a design of the illuminated plate of so-called float glass (soda lime silicate glass) is possible. In addition, the plate can be produced here by means of 3D internal laser engraving with various designs, characters,

Letters, logos, ornaments etc. be provided. Such treatments are not or hardly visible in normal viewing without lighting. By illuminating a peripheral edge of the illuminable plate by means of a lighting element such Innenlasergravuren in the otherwise clear plate surface clearly visible. Furthermore, the use of a safety glass for the illuminated plate is possible.

In addition, the invention provides that an interior of the central hollow chamber of the spacer element of the insulating glass element together with the at least one lighting element located therein at least with respect to other areas of the

Insulating glass unit is gas-tight or lockable. Alternatively or additionally, it can also be provided that at least one region between the at least two mineral glass plates is sealed or can be closed in a gas-tight manner relative to the central hollow chamber. The remaining area may be similar to a conventional insulating glass unit, in which two or three mineral glass plates are installed in a frame and the interior space located between the discs is sealed gas-tight, especially under greatly reduced internal pressure, for example. By establishing a negative pressure or partial vacuum located there.

Optional, i. In addition, or instead of the gas-tight closure of the central hollow chamber, the insulating glass unit according to the invention may also be formed in such a way that the interior of the central hollow chamber together with the at least one lighting element therein gas-tight against a located between the at least two mineral glass plates isolated area and / or against a between one of the at least two mineral glass plates and the illuminable plate located insulated first region and / or opposite to a located between the other of the other at least two mineral glass plates and the illuminable plate insulated second region is completed.

In an optional embodiment of the invention

Insulating glass unit, the middle hollow chamber forms a cooling profile or a heat sink. Alternatively, however, it can also be provided that the middle hollow chamber receives such a cooling profile or such a heat sink in its interior. In a further embodiment of the insulating glass unit according to the invention is at one of the edge of the illuminable plate facing side of the cooling profile or heat sink at least one strip-like or by several juxtaposed or spaced lighting means formed on or on, which in the activated state, the edge of the illuminable plate illuminates and / or radiates into the marginal edge of the illuminable plate.

This cooling profile or this heat sink may be formed, for example, by a continuous or single or multiple interrupted bar, which is received in the central hollow chamber or forms part of this central hollow chamber.

In particular, in a variant of the insulating glass unit, the strip forming the cooling profile or the heat sink may be a strip profiled in cross-section. In this case, for example, it may be provided that the strip forming the cooling profile or the heat sink is in heat-transmitting contact with at least one inner side surface of the middle hollow chamber. This bar may, for example, a profile similar to a double-T-profile with U-shaped top o. The like. Have.

According to another option, the lighting element is located at

Insulating glass unit according to the invention on the heat sink or the cooling profile or is there via a heat transfer layer (for example, a tape, a suitable coating, etc.) connected thereto. That is, in the thus configured insulating glass unit, the lighting element faces one of the illuminable plate

Support surface of the cooling section or the heat sink connected via a heat transfer layer with this.

A particular advantage of the insulating glass unit according to the invention is that the heat sink received in the central hollow chamber together with the

at least one connected thereto and / or mounted thereon lighting element can be modular, so that such a modular unit of heat sink and lighting elements interchangeable and / or displaceable in the longitudinal direction and / or removable from the middle hollow chamber and easily and quickly releasably in the middle hollow chamber is mounted or mounted.

For this purpose or in this context, it may be provided, for example, that the modular structural unit of heat sink and lighting elements can be removed or inserted into the central hollow chamber through an opening located in the middle hollow chamber at the front side. The gas-tight seclusion of the module or of the modularly constructed lighting module with heat sink compared to the remaining area of the

Insulating glass unit, in particular with respect to the space between the panes, can be combined with the interchangeability particularly advantageously if the opening is openable and closable on one side of one of two end faces of the central hollow chamber, in particular after inserting the respective desired module and / or after replacing it with another one Module.

In the case of the insulating glass unit according to the invention, optionally at least one of the lateral hollow chambers of the spacer can be box-shaped or

have rectangular cross-section. Optionally, the spacer may be constructed so that symmetrical to a plane passing through the longitudinal axis, that the lateral cavities or cavities are symmetrical or designed. In this embodiment, the distance between each other by means of the spacer glass panes are thus equidistant from the central hollow chamber with the lighting element therein.

An optionally to be understood embodiment variant of the insulating glass unit according to the invention can provide that a cross-sectional width of the central hollow chamber is smaller than the distance of the at least two mineral glass plates from each other defining total cross-sectional width of the spacer element. Also conceivable is a variant of the insulating glass unit, in which the cross-sectional width of the central hollow chamber comprises about 30% to about 80% of the total cross-sectional width of the spacer element defining the distance between the at least two mineral glass plates. A practical useful variant of the insulating glass unit can, for example, a cross-sectional width of the hollow chamber-shaped and with rectangular or

square cross-section provided central hollow chamber, which is about half as wide as the spacer or slightly wider.

However, another useful embodiment variant of the insulating glass unit can also provide a cross-sectional width of the central hollow chamber, which corresponds to a distance of the at least two mineral glass plates from each other defining total cross-sectional width of the spacer, so that a continuous width of the entire spacer element together with a part thereof forming middle hollow chamber approximately equal is. In such a variant, it may be advantageous if the mineral glass plates are not each directly on the lateral flanks of the spacer or on its two outer hollow chambers and / or on the middle hollow chamber is mounted, but that between the mineral glass plates and the respective lateral hollow chambers each strip-shaped or box-shaped or cuboidal

Spacers are located. Furthermore, spacers may in principle also be made of any material, such as e.g. aluminum, plastic, chrome-nickel steel, thermoplastic material (e.g., so called TPA - so-called thermoplastic spacers), silicone foam, or a combination of several materials. Spacers made of thermoplastic material or such TPA can be applied, for example, by means of a suitable spraying process directly in the course of assembly of the glass panes or the insulating glass unit according to the invention.

The last-mentioned variant of the insulating glass unit or of the spacer in particular aims at a so-called "warm edge" solution. This solution is the

Consideration that such spacers in insulating glass contribute significantly to the overall performance of Mehrscheibenisolierglas in terms of thermal insulation. The heat conduction of the spacers is specified in the form of the "PSI value", which means the length-related heat transfer. Become

Used spacers made of aluminum profile, this is a comparatively unfavorable PSI value to accept, which may be about 0.1 1 1 W / mK. In contrast, comparatively favorable PSI values in the range from about 0.035 to about 0.042 W / mK can be achieved with more modern spacer systems. An important aspect of the last-mentioned variant lies in a reduction of the profile to the "core region", wherein both lateral chambers omitted or at least reduced in volume so far that the total width of the spacer of the cross-sectional width of the central hollow chamber with the illumination element therein - if necessary with associated heat sink - corresponds. On the resulting free side surfaces of such a core profile (spacers; spacer) can then be applied with modern systems in insulating glass, for example, a so-called "TPA", which is a so-called. Thermoplastic spacer to understand. Such a TPA can be applied, for example, in the form of a spraying process directly during the assembly of the glass sheets. Basically, conventional commercial

Distance holder systems made of any material such. made of aluminum, plastic, chrome-nickel steel, thermoplastic material, silicone foam, or a combination of several materials.

Furthermore, an optional variant to understand the

Insulating glass unit according to the invention provide that the pointing to the illuminable plate, facing each other and / or parallel surfaces Inner sides of the at least two lateral Hohlkammem together with an upper side of the central hollow chamber in cross section a U-shaped and / or groove-like receptacle or U-shaped groove for the illuminable plate (formed, for example, by a Plexischeibe or by a PMMA plate) ,

In the insulating glass unit, the illuminable plate can be embedded in the U-shaped and / or groove-like receptacle and / or in each case via lateral damping layers and / or adhesive layers in positive and / or adhesive contact with the inner sides of the lateral hollow chambers.

Moreover, in the case of the insulating glass unit according to the invention, the illuminable plate can be embedded in the U-shaped and / or groove-like receptacle and / or can be in positive contact with the upper side of the middle hollow chamber via a lower-side transparent damping layer. This underside transparent

Damping layer on which the plate can be supported on the edge, in particular can form a sealing cover for the underlying central hollow chamber, so that there located openings for the passage of light, which is required to be radiated from the lighting element in the plate, gas-tight and / or hermetically sealed. Thus, the insulating glass unit according to the invention may be configured in such a way that the lower side transparent damping layer, the central hollow chamber gas-tight relative to the located between the at least two mineral glass plates isolated area and / or against the located between one of the at least two mineral glass plates and the illuminable plate insulated first region and / or opposite to the isolated between the second of the at least two mineral glass plates and the illuminable plate located opposite the second.

Preferential or optional, the insulating glass unit can continue to be designed in such a way that the upper edge of the illuminable plate lying there upper edge of the central hollow chamber with recesses for the passage of the light emitted by the lighting element, for example electromagnetic light radiation to the plate and / or to their entry into the Plate is provided, which may be meant in particular that the material bridge on which the plate or Plexischeibe rests, is provided with suitable recesses for the passage of the light emitted by the illumination unit, if necessary. These recesses can be formed, for example, by bores or other openings which are arranged regularly and / or at regular intervals from one another in the longitudinal extension direction of the Spacer elements are arranged. This may mean, for example, regular and / or regularly spaced-apart openings or circular openings or the like, which allow a passage of the light. Alternatively, the apertures or openings may also be arranged in an irregular arrangement and / or at unequal distances from one another in the longitudinal extension direction of the spacer element. Alternatively, longitudinal slots or a continuous longitudinal slot may be provided instead of circular or differently shaped openings.

In the case of the insulating glass unit according to the invention, the entire profile can be formed by a metal extruded profile, in particular by an aluminum extruded profile. The heat sink may, for example, also be formed by such an extruded aluminum profile. Other materials are suitable for the heat sink in question, as long as they can dissipate the heat generated by the lights or the lighting unit in the activated state sufficiently.

Optionally, the entire profile can also be characterized by a non-metallic profile, in particular by a plastic extruded profile or by a profile

fiber-reinforced plastic o. The like. Be formed, and here, too, the heat sink, for example, may be formed by such an aluminum extruded profile or by a profile of another suitable material. In some cases, profiles made of a metal-plastic combination may also be suitable.

The entire profile can be displayed on all four sides of a window or as a window

Building limitation used insulating glass unit be provided. However, it may also be sufficient to anchor the illuminable plate on only one side in the manner described, for example. At its lower edge. Preferably, however, the illuminable plate is on two opposite sides - i. top and bottom or left and right - held in corresponding profile pieces, but it may be sufficient to provide only one-sided coupled lighting, so that more frame sections of the insulating glass unit can be designed differently than described above, in particular with simplified profiling, as some components as lighting and heat sink etc. can be omitted.

In summary, in other words, the present invention may be characterized as follows. So is a technical solution for the installation of a

Light plate in multi-pane insulating provided and realized, which in particular a solution for the "integration of a light panel made of plastic in a multi-pane insulating glass element "is meant. An important aspect here is a special profile that serves as a spacer for the production of a

Mehrscheibenisolierglasscheibe with almost conventional glass structure and gas filling can be used.

In a central groove of the special profile, a transparent plate, such as a plastic plate, are held, which can be illuminated by openings on the profile bottom by means of lighting, preferably in the form of LED illuminated spots or light strips o. These openings are gas-tight covered with a transparent material, for example by the transparent plastic plate is glued to the profile base. An additional profile cavity accommodates the LED lighting used, for example. The angle connectors are split so that the LED bar can be installed after assembly and after the gas filling of the insulating glass unit. The LED bar can also be replaced in the same way without interfering with the hermetically sealed space between the panes of the insulating glass unit.

The light plate or illuminable plate itself is typically not an inventive part of this development, but may be formed in particular by an already commercially available product. The essence of the light panel is that the panel is basically clear and transparent like glass, but when the edges are fully illuminated, it begins to "shine" completely. Purely as a precaution should be noted at this point that each referred to as mineral glass plates outer glass sheets or plates can in principle be designed as plastic glass plates, or may consist of organic glass. Therefore, if at any arbitrary point of this description and the claims of "mineral glass plates" is mentioned, this term can also each "glass plate (s)" or by

"Plastic glass plate (s)" or "glass plate (s) of organic material" (such as PMMA o. The like. Plastic material) or in principle by "glass plate (s)

inorganic material "are replaced, without this affecting the actual core idea of the present invention, changed or even affected.

In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail.

Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are merely examples, such as

It should therefore be emphasized at this point that the relatively concrete and objectively described with reference to the figures embodiments laid down in the claims and in the general part of the description in a variety of embodiments defined inventive concept in any way diminish or limit.

The schematic cross section through a partial section of a first embodiment variant of an insulating glass unit 10 according to the invention, illustrated in FIG. 1A, illustrates the construction of a lower frame section 12 which can continue in the same or similar manner on lateral and upper frame sections (not shown here). FIG. 1B shows the first embodiment variant of the insulating glass unit 10 shown in cross section in FIG. 1A in a cross-sectional view of the lower frame section 12 and the transparent layers connected thereto. The first variant of the insulating glass unit 10 according to the invention, shown in FIGS. 1A and 1B, provides that an illuminable plate 20 made of transparent material is arranged between two mineral glass plates 16 and 18 held at a defined distance from each other by means of a spacer element 14 , The spacer element 14 may in this case be formed continuously from a material, such as a metal or a plastic. Alternatively, material combinations may be suitable. The two mineral glass plates 16 and 18 may in particular be formed by so-called float glass, while the illuminable plate 20 located therebetween is preferably made of organic glass, such as PMMA, so that it can act as a light plate by external light irradiation.

In principle, the use of inorganic glass for the illuminable plate 20 is possible.

The interpane spaces 22 between the first mineral glass plate 16 and the second mineral glass plate 18 and the two outer float glass plates 16 and 18 or between the first mineral glass plate 16 and the illuminable plate 20 and / or between the second mineral glass plate 16 and the illuminable plate 20 are through the described below gas-tight closed, so that in the space between the panes 22 in particular a suppression and / or a noble gas filling o. The like. Can be located.

The illuminable plate 20 located between the two mineral glass plates 16 and 18 and spaced therefrom is at least at its lower

longitudinal edge 24 held by or by the spacer element 14 and / or worn and in its parallel arrangement and location to the two

Mineralplasplatten 16 and 18 stabilized, which are also positioned in parallel relationship to each other and held on the spacer 14. The spacer element 14, which defines the distance between the two mineral glass plates 16 and 18, is formed by a hollow profile 15, which comprises a plurality of adjoining hollow chambers 26 and 28. At the two lateral hollow chambers 26 of the hollow profile 15 each adjacent to one of the two outer mineral glass plates 16 and 18, which rests there in each case.

Optionally, in each case a desiccant may be introduced in the lateral hollow chambers 26. On the central hollow chamber 28 of the spacer 14, which by

Material bridges 30 each with the two spaced apart lateral

Hollow chambers 26 is connected, is the illuminable plate 20 with its longitudinal edge edge 24 on. In the middle hollow chamber 28 is at least one strip-like or by a plurality of juxtaposed or spaced lighting means formed lighting element 32, the edge 24 of the illuminable plate 20 illuminates in the activated state and / or radiates into the peripheral edge 24 of the illuminable plate 20, whereby the Insulating glass unit 10 according to the invention obtains the special character of an insulating glass unit 10 which can be illuminated uniformly and / or with specifically producible effects. The illuminable plate 20 consists for example of organic material such as a suitable transparent plastic such as so-called. Acrylic glass or PMMA, which has a refractive behavior for edge-coupled light from the illumination source 32, resulting in a uniform diffuse radiation of the entire plate surface with simultaneous loss of part or Loss of the transparent properties of the plate 20 leads. Likewise is a use of a

illuminable plate 20 made of inorganic material, such as float glass, possible, which can also be applied at the edge with light from the illumination source 32.

The illumination element 32, which may be formed, for example, by an LED strip, is mounted on a profiled heat sink 34, typically below

Interposition of a heat-transfer adhesive strip 35 or a

heat transferring layer.

An interior of the central hollow chamber 28 of the spacer element 14 of the insulating glass element 10 together with the lighting element 32 therein is sealed gas-tight. The remaining area may be similar to a conventional insulating glass unit in which two mineral glass plates are installed in a frame and the interior space between the panes is sealed gas-tight, in particular under greatly reduced internal pressure, for example by establishing a vacuum or partial vacuum located there and / or by introducing a noble gas filling.

The illuminable plate 20 is in its lower part by means of

Flocking layers 36 are held and inserted largely free of play between the parallel wall sections of the lateral hollow chambers 26. The seated on the top 38 of the central hollow chamber 28 lower longitudinal edge edge 24 of the transparent plate 20 is separated from the top 38 by a transparent film strip 40 which is glued or otherwise attached to the top 38 and for the gas-tight closure of the interior of the middle Hollow chamber 28 relative to the space between the panes 22 and opposite the two disc spaces 22 provides. This is useful because on the top 38 several juxtaposed breakthroughs 41 are provided, which are used as light passages for coupling of the

Illuminating element 32 radiated light in the lower peripheral edge 24 of the

serve transparent plate 20. Thus, the transparent film strip 40 also ensures the gas-tight covering of these openings 41, so that by means of the film strip 40, a transparent, gas-impermeable profile bottom can be produced.

Sealing tapes 42, which may be formed, for example, by Butyldichtbänder are located respectively at lower corners of the outer side walls of the two lateral hollow chambers 26 so that the adjoining mineral glass plates 16 and 18 are each sealed to the outside and a primary seal can arise. In connection with the spacer element 14 and the film strip 40, hermetically sealed-off interpane spaces 22 can thus be ensured.

The modular unit, consisting of heat sink 34 together with glued adhesive strip 35 and lighting element 32 located thereon can, if necessary, be serviced and exchanged here not shown removable corner angle, without affecting the function of the double glazing. The removable corner angle must in the assembled state, the middle hollow chamber 28 in no way gas-tight, because the upper portion of the insulating glass unit 10 is closed with the disc spaces 22 relative to the central hollow chamber 28 gas-tight. In addition, FIG. 1 B and FIG. 2 each reveal an electrical supply line 44 for supplying energy to the lighting element 32.

FIGS. 2A to 2H now show different sections, respectively

Assembly steps of individual components of the insulating glass unit 10 according to the invention as shown in FIG. 1 A and 1 B. By way of example, the assembly of the invention

Insulating glass unit 10 shown with reference to a lower corner portion, but for other corner sections may result in a corresponding procedure during assembly. In a first step, which is shown in FIG. 2A, the spacer element 14 is constructed by joining together a first hollow profile section 15a and a second hollow profile section 15b by means of an angular connection element 54. Preferably, the first hollow profile section 15a joined together by means of the connecting element 54 and the second hollow profile section 15b form an angle of approximately 90 ° to one another. Basically, other angle amounts between the

Depending on the desired configuration of the insulating glass unit 10, hollow profile sections 15a and 15b may be provided. For a stable connection of the hollow profile sections 15a, 15b to the connecting element 54, the connecting element 54 has a plurality of legs 50, in box-shaped or rectangular openings 58 of the respective

Hollow chambers 26 of the hollow profile sections 15a, 15b can engage.

In a further step, which can be seen in FIG. 2B, the illuminable plate 20 is now to be inserted largely free of play into a free region 52 between the parallel wall sections of the two lateral hollow chambers 26 of the hollow profile sections 15a, 15b, so that they are from or through the Distance element 14 is held and / or worn. Here is the illuminated plate 20 on the middle

Hollow chamber 28 of the spacer 14 with their respective marginal edges 24 rest. For this purpose, facing the illuminable plate 20, facing and / or parallel surfaces having inner sides of the at least two lateral hollow chambers 26 together with an upper side of the central hollow chamber 28 in

Cross section form a U-shaped and / or groove-like receptacle 52 or U-shaped groove 52 for the illuminable plate 20. By suitable means, the illuminable plate 20 can also be fixed or embedded in its intended position, for example with the aid of an aforementioned Beflockungsschicht 36. In addition, on the upper side 38 of the central hollow chamber 28, a transparent foil strip 40 glued to later for a gas-tight Completing the interior of the middle

To provide hollow chamber 28.

Then, for example, formed by Butyldichtbänder sealing strips 42 at the lower corners of the outer side walls of the lateral

Hollow chambers 26 of the spacer 14 are applied (see Fig. 2C). Finally, it is possible to position the mineral glass plates 16, 18 in a parallel arrangement on the spacer element 14, as shown in FIG. 2D. Here, it is provided that the mineral glass plates 16, 18 under installation of the sealing strips 42 to be mounted on the spacer element 14, so that the voltage applied to the sealing strips 42 mineral glass plates 16, 18 are each sealed to the outside.

Furthermore, a trained example by an LED strip lighting element 32, preferably with the interposition of a

heat-transferring adhesive strip 35 or a heat-transferring layer, be mounted on a profiled heat sink 34, so that the two elements 32, 34 can be jointly introduced into an interior of the central hollow chamber 28 of the spacer 14 (Fig. 2E). It may already be sufficient merely to integrate a lighting element 32 into the middle hollow chamber 28 of one of the hollow profile sections 15a, 15b, but the arrangement of a plurality of lighting elements 32 in FIG several hollow profile sections 15a, 15b readily possible. In the activated state, the lighting element 32 can illuminate the respective peripheral edge 24 of the illuminable plate 20 or can radiate into the peripheral edge 24 of the illuminable plate 20. For this purpose, a plurality of apertures 41 may be provided on the top 38 of the central hollow chamber 28, which as light passages for coupling of the

Illuminating element 32 radiated light into the respective peripheral edge 24 of the illuminable plate 20 are intended to serve. An interior of the central hollow chamber 28 of the spacer element 14 together with the lighting element 32 located therein can be closed gas-tight following.

In a further step (Figure 2F), an electrical lead 44 is connected to

Power supply of the lighting element 32 to the lighting element 32 electrically connected. Finally, a corner bracket 48 is attached to the spacer 14 (see Fig. 2G). Here project leg 56 of the corner angle 48 in the

Hollow chambers 28 of the hollow profile sections 15 a, 15 b, and close off the corner regions of the spacer element 14. The removable corner angle 48 in the assembled state, the middle hollow chamber 28 of the hollow profile sections 15a, 15b not gas-tight, since the upper portion of the insulating glass unit 10 with the disc spaces 22 against the central hollow chamber 28 is already completed gas-tight. As now clearly shown in FIG. 2H, the area 60 of the corner angle 48 is freely accessible. The removable corner bracket 48 can so anytime again from the connection with the

Hollow profile sections 15a, 15b are dismantled, if necessary, the heat sink 34 together with glued thereto adhesive strip 35 and befindlichem it

Remove lighting element 32 from the middle hollow chamber and to maintain or replace. Likewise, the electrical supply line 44 can be reached by disassembling the corner angle 48. The remaining components of the insulating glass unit, such as the illuminable plate and the mineral gas plates 16, 18 need not be dismantled, so gas-tight closed spaces, such as

Interspaces 22, can remain untouched and the function of insulating glazing is not impaired.

The second embodiment variant of the insulating glass unit 10 shown in FIG. 3 essentially differs from the first variant shown in FIGS. 1A and 1B by the other design of the two lateral hollow chambers 26, which are narrower here, so that they are substantially vertical the middle one

Hollow chamber 28 are aligned. The spacer element 14 thus has a width here, which extends over the middle hollow chamber 28 and the lateral arranged above Hollow chambers 26 extends. Lateral spacers 46, such as thermoplastic spacers 46, provide for the gas-tight connection of the two mineral glass plates 16 and 18, respectively, while the two sealing bands 42 (see FIG. In particular, by using thermoplastic spacers 46 ideal results could be achieved. In principle, conventional commercially available spacer systems 46 made of any material such as

Aluminum, plastic, chrome-nickel steel, silicone foam, or a combination of several materials are used.

In both embodiments, the lighting unit 32 formed by an LED stripe, for example, can be serviced and exchanged via removable corner angles, which can be pushed into the profiles 15 on the front side, without impairing the function of the insulating glazing. The claims to one

Insulating glazing (freedom from fogging, inspection and gas-tightness) is always guaranteed.

The spacer holder profile 15 is basically material independent and can be made of metal, plastic or a combination of the two.

In FIGS. 4A to 4H, different assembly steps of individual components of the insulating glass unit 10 according to the invention as shown in FIG. 3 are now likewise shown in detail. Again, in a first step (see FIG

Distance element 14 are constructed by a first hollow profile section 15a and a second hollow profile section 15b are joined together by means of an angular connecting element 54. The first hollow profile section 15a and the second hollow profile section 15b joined together by means of the connecting element 54 preferably again form an angle of approximately 90 ° with respect to each other, although in this case also other angular amounts can be provided between the hollow profile sections 15a and 15b. For a stable connection of the hollow profile sections 15a,

15b to the connecting element 54, the connecting element 54 a plurality of legs 50 which in the box-shaped or rectangular openings 58 respectively

Hollow chambers 26 of the hollow profile sections 15a, 15b can engage. In contrast to the insulating glass unit 10 shown in FIGS. 2A to 2H, the lateral ones are

Hollow chambers 26 narrower, so that they are largely aligned vertically with the central hollow chamber 28. Furthermore, in the step shown in Fig. 4B, the illuminable plate 20 in a free area 52, a receptacle 52 and a groove 52 between the parallel wall sections of the two lateral hollow chambers 26 of

Hollow profile sections 15a, 15b used largely free of play, so that the illuminable plate 20 is held by or by the spacer 14 and / or worn.

Again, the illuminable plate 20 on the middle hollow chamber 28 of the

Distance element 14 rest with their respective marginal edges 24. In addition, the illuminable plate 20 can be fixed or embedded by suitable means in their intended position, for example, again with the aid of a

Flocking layer 36. On the upper side 38 of the middle hollow chamber 28, a transparent film strip 40 can be glued, which is to ensure a gas-tight closure of the interior of the central hollow chamber 28.

Now, as shown in Fig. 4C, a turn, e.g. formed by an LED strip lighting element 32, which is mounted with the interposition of a heat-transfer adhesive strip 35 or a heat transfer layer on a profiled heat sink 34, are introduced into the interior of the central hollow chamber 28 of the spacer 14. It may already be sufficient to integrate a lighting element 32 only in the central hollow chamber 28 of one of the hollow profile sections 15a, 15b. Nevertheless, the arrangement of multiple lighting elements 32 in several hollow profile sections 15a, 15b is possible. Again, the interior of the central hollow chamber 28 of the spacer 14 in the

Following together with the lighting element 32 therein gas-tight

be completed. In a further step (FIG. 4D), the electrical supply line 44 for supplying energy to the lighting element 32 is electrically connected to the lighting element 32.

Now, the corner angle 48 can be attached to the spacer element 14, wherein leg 56 of the corner angle 48 engage in the hollow chambers 28 of the hollow profile sections 15a, 15b, and the corner regions of the spacer element 14 complete (Fig.

4E). The removable corner angle 48 must also in the assembled state, the middle hollow chamber 28 of the hollow profile sections 15a, 15b not gas-tight, since the upper portion of the insulating glass unit 10 with the later arising

Disc spaces 22 against the middle hollow chamber 28 is already completed gas-tight. As FIG. 4F shows, lateral spacers 46, preferably thermoplastic spacers 46, can now be attached to the mineral glass plates 16, 18. Subsequently, the mineral glass plates 16, 18 together with the spacers 46 fastened thereto are applied to the outer side walls of the respective hollow profile sections 15a, 15b of the spacer element 14 (FIG. 4G). Again, it is planned that

Mineral glass plates 16, 18 in a parallel arrangement to each other on the spacer 14 to position. By such an arrangement with the spacer 46th

equipped mineral glass plates 16, 18, the mineral glass plates 16, 18 are also sealed to the outside.

It can clearly be seen in FIG. 4H that, even in this embodiment, the region 60 of the corner angle 48 is freely accessible. The removable corner bracket 48 can be disassembled at any time from the connection with the hollow profile sections 15a, 15b to remove the cooling body 34 together with glued thereto adhesive strip 35 and thereon lighting element 32 from the central hollow chamber and to maintain or replace if necessary. Likewise, the electrical supply line 44 can be reached by disassembling the corner angle 48. Again, the other components of the insulating glass unit, such as the illuminable plate and the

Mineral gas plates 16, 18 are not dismantled so that gas-tight closed spaces, such as the space between the panes 22, can remain untouched and the function of a glazing is not impaired.

FIGS. 4E ^* to 4H ^* now show alternative assembly steps to the procedure shown in FIGS. 4E to 4H. First, the corner angle 48 is to be attached to the spacer 14 here by legs 56 of the corner angle 48 in the hollow chambers 28 of the hollow profile sections 15a, 15b engage and so the corner regions of the spacer 14 complete (Fig. 4E ^* ). Subsequently, spacers 46, preferably thermoplastic spacers 46, are laterally attached to the hollow profile sections 15a, 15b or the spacer element 14 in the region of the cavities 26 (compare FIG. 4F ^* ). As FIG. 4G ^* shows, the mineral glass plates 16, 18 can then be attached to the spacer element 14 in parallel arrangement with one another. Here, it is provided to mount the mineral glass plates 16, 18 under abutment with the spacers 46 on the spacer element 14, so that the adjacent to the spacers 46 mineral glass plates 16, 18 are each sealed to the outside.

As now also clearly shown in FIG. 4H ^* , the area 60 of the corner angle 48 is freely accessible. Thus, the removable corner angle 48 at any time from the Connection with the hollow profile sections 15a, 15b are dismantled to remove if necessary, the heat sink 34 together with glued adhesive strip 35 thereon and lighting element 32 from the middle hollow chamber and to maintain or replace. Likewise, the electrical supply line 44 can be reached by disassembling the corner angle 48. Again, the remaining components of the insulating glass unit, such as the illuminable plate and the mineral gas plates 16, 18 need not be dismantled, so gas-tight closed spaces, such as the disc spaces 22, remain untouched and the function of

Insulating glazing is not affected.
