Description

Large-surface luminaire made of flat or curved or partially curved glass panes and / or KunstStoffScheiben as

individual discs or as a composite and method for its production

The invention relates to a large-area lamp made of flat or curved or partially bent glass sheets and / or plastic discs as individual panes or as a composite and a method for their preparation, in particular with a homogeneous light field and for roofing. For this purpose, flat glass panes and / or plastic pane are mounted flat or bent to form a composite as a double or multiple composite. Glass types can be normal flat glass panes, such as float glass as well as other types of flat glass. As a plastic disk, for example, acrylic glass comes in

Consideration. Advantageously, the composite for reasons of weight saving with thin flat glasses and off or

Plastic discs formed. Single-pane safety glass, chemically hardened or solidified glass and thermally tempered glass can also be used as composite or as individual glass.

The conventional light sources have been in the last few years

Changed a lot over the years. When the classic incandescent lamp converted the most energy into heat, the energy-saving lamps became much more effective. The efficiency increased significantly, the durability of an energy-saving lamp was significantly increased. Also, the fluorescent tubes have been significantly improved in recent years. A big step in the direction

Increase in efficiency brought the use of LED technology.

Currently, for ceiling glazing for indirect

Lighting, diffuse flat glasses, such as frosted glass,

sandblasted or satined glass used as single or laminated glass. Thus, the light, radiating mostly scattered by fluorescent tubes and creates the impression of a surface light. The disadvantage is still in one relatively high energy consumption, the fluorescent tubes have a relatively short life. Only in recent years have LED light fittings been increasingly installed with lower energy consumption. Meanwhile, these LEDs are built so small that they can easily laminate between two glass panes. The energy consumption has been drastically reduced again, the luminosity of the LED is remarkable. All hitherto mentioned technical

Possibilities of converting electricity into

Light energy have one thing in common, they are spot lights that can not produce large-area light with a homogeneous light density. In contrast, OLED technology fulfills the requirements for a true surface light source. A system for light scattering is no longer necessary. The result is an absolutely glare-free light, which comes very close to natural daylight. However, the energy consumption of OLED is currently still above that of an LED.

A power supply is also always needed, such as a battery, a battery or the public

Power supply network is available. The use of bent glass is based on conventional

Lamps almost impossible. The previously for the

Production of laminated glass between the respective ones

Slices used films often also meet the

Requirements especially in wet rooms and at

Outdoor applications not, it comes in laminated glass very often delamination phenomena.

Admits are embedded in laminated glass LED, which, however, do not form a homogeneous luminous surface and also a

Need wiring that is visible.

A composite pane with integrated lighting devices is described in DE 10 2012 109 180 A1, wherein the composite pane comprises at least two panes made of glass or plastic, in which the lighting devices are embedded, the lighting devices each being in the form of elongated panes Light strips with a number on or on these light strips arranged luminous surfaces, which are formed by light-emitting diodes, are present and wherein the elongated light strips in each case from the end face of the composite disc forth in the

Lumen associated cavities inserted in the composite disk and can be removed from this for revision purposes. According to the invention, organic light-emitting diodes (OLEDs) are provided, which are arranged flat on the light strips, wherein the functional layers can be arranged in the longitudinal direction continuously or even interrupted, wherein these OLEDs are preferably so controlled that

Coordinates and / or dimensions and / or properties of the active in the on state lighting surface are variable.

The object of the invention is to create large-scale luminaire from plan or curved or partially curved glass sheets and plastic discs as individual slices or as a composite and a method for their preparation, with a reliable surface lighting while maintaining high stability is to be achieved and opposite

Weather conditions is independent.

With the invention is achieved in the specified application that large-scale lights are made of flat or curved or partially curved sheet glass panes and suitable plastic discs, such as acrylic glass, wherein at least one electrical light emitting surface and / or photovoltaic layer is applied to at least one of the surfaces of the glass or plastic discs , Wherein the luminous area and / or photovoltaic layer in particular in a superposed or partially

superposed arrangement are isolated from each other.

This creates an individual, easily stable and at the same time producible with little effort large-scale lights. In addition, by bending the respective discs, static advantages are achieved which increase the stability. With more than one Luminous area, so with two, three or more illuminated areas can be in terms of effective light area

implement scalable lights, which also depending on

If necessary, can also be combined with a photovoltaic layer. Here, superimposed arrangements of these come into consideration, in which case for a sufficient

Protection against contact of the illuminated surface to the photovoltaic layer is to be ensured.

Thus, the invention allows the photovoltaic layer and the luminous surface with a connecting layer on a surface of a Glasscheibel or plastic disc together next to each other, one above the other and each individually, ie

For example, only the luminous area next to each other or

are arranged one above the other. Provided is also an offset or overlapping arrangement.

The use of plastic discs has the advantage that it leads to a significant reduction in weight of the large-area lamp, while still providing high stability

Arrangement is achieved.

Advantageously, the luminous area and in particular the

Photovoltaic layer arranged in a flat, unbent area of the glass sheets and plastic sheets. This also allows lighting surfaces and photovoltaic layer

which can not be bent or bent.

Furthermore, a method for producing a

large-area lamp made of plan or curved or partially curved glass panes or plastic discs created, which comprises the steps of applying a bonding layer on a first surface of a cleaned glass or plastic pane and applying a luminous surface and / or a photovoltaic layer at least partially on this compound layer and / or on the first surface of the glass or plastic disc comprises, with a simple construction for different

Further processing steps is achieved. Depending on

If and when required, this large-area lamp remains as a single glass and is a post-processing, which includes, for example, the ready electrification and the addition of constructive elements such as frames,

supplied t.

As needed, the steps read on the second

Surface of the glass or plastic discs

Repeat, so that applying the bonding layer at least partially on the cleaned second surface of the glass or plastic discs and the application of the luminous surface and / or the photovoltaic layer at least partially on this compound layer and / or on the first surface of the glass or plastic disc and then the post-processing ,

It is thus a simple structure achievable, with which a lamination is provided, whereby also by means of suitable

Materials for the bonding layer can dispense with a lamination, wherein using suitable materials for the bonding layer lamination in a first or second steps is nevertheless not excluded. However, this structure has a lower overall stability than a Mehr Scheibenverbund.

On the available surface of the glass sheets or plastic sheets can be arranged one-piece lighting surfaces or multi-part lighting surfaces, depending on the individual application. Thus, in addition to adjustable intensities through individually switchable areas also in different colors emitting

Combine illuminated surfaces.

Thus, the luminous surface can be one, two or more parts run and up to the edge of the respective luminous surface and / or glass or plastic disc and / or from the edge of the arrange each glass or plastic disc and each spaced from each other. Thus, on the one hand, the maximum available area is used for the illuminated area. Also intermediate distances are in multiple parts

built-up luminous surfaces avoided. In particular, when juxtaposing multiple lights dark transitions are avoided or at least significantly reduced. On the other hand, it is achieved with a spacing that the connection layers lying directly on top of each other, which have very good adhesion to the glass panes or plastic panes, also adhere very well to one another and to one another, as a result of which the respective luminous area is subject to tensile stress

be relieved and thus replacement or

Delamination be avoided.

To avoid trapped air, to allow larger thicknesses or special designs of the luminous surfaces or photovoltaic layers and to compensate for other differences in height or thickness, it is envisaged that the required

Connecting layer is used not only in the thickness corresponding to the respective needs, but at least in areas also repeatedly arranged one above the other, if necessary to obtain a required thickness. This can be almost any thickness differences or

Compensate gap differences reliably.

Especially with bent glass panes or

Plastic discs are preferably films for the

Luminous surface and the photovoltaic layer used. The bent laminated glass elements can in many cases take over the roof function. A simple application case is door-glazing. By installing many curved laminated glass elements, it is possible to roof over from bus shelters to large hall glazing and bridge glazing. Curved glass or plastic discs also have the advantage that a self-cleaning is better than with flat glass or plastic discs, as flat glass sheets or plastic discs would be inclined to arrange. The products from the field of photovoltaic as

Photovoltaic layer and surface light sources as luminous surfaces flow together in a new product.

Advantageous embodiments of the large-area lamp are shown in claims 2 to 11, the method of claims 13 to 17.

In a further development, on at least one side of the glass pane or plastic pane with the at least one electrical lighting surface and / or photovoltaic layer, a further glass pane or plastic pane is arranged in a composite. As a result, the stable construction of a Mehrfachverbundglases is achieved, the combination with plastic discs leads to a significant reduction in weight, the stability is still maintained.

In a further development, the luminous area and / or the photovoltaic layer are adjacent to one another and / or flat

one above the other on the glass and / or plastic disc are arranged, wherein luminous area and the

Photovoltaic layer by means of a bonding layer

are insulated from each other and at least partially on at least one or between two or more composite films as a bonding layer on one or between two in each case

Glass panes and / or plastic discs are arranged, wherein between each two glass panes and / or

Plastic discs in areas without luminous surface and the photovoltaic layer at least one connecting layer

is available. As a result, on the one hand, in particular in the case of full coverage of the connecting layer with the luminous area or the photovoltaic layer, a high level is achieved

Adhesion between the glass panes or plastic discs and the respective luminous area or photovoltaic layer achieved. For non-planar coverage, so only a partial area arrangement of the connection layer to the luminous area or

Photovoltaic layer are optionally occurring optical Loss of the tie layer avoided. Here, however, only part of the possible structural stability of

Arrangement achieved. In addition, layers can be

stacked, overlapping or partially overlapping

Arrangements of the luminous area and the photovoltaic layer, and each realize with each other, wherein the

Connection layer allows the mechanical separation and in particular the electrical insulation, since each of the

Connecting layer between the surfaces of the adjacent glass sheets and / or plastic discs on the one hand and the luminous surface and the photovoltaic layer on the other hand is arranged.

Advantageously, the connection layer is applied at least on one side to the photovoltaic layer and / or luminous surface or is part of the photovoltaic layer and / or luminous surface, which is why the method becomes more efficient and simpler. Errors in the process can be avoided.

Furthermore, advantageous on the luminous surface and / or

Photovoltaic layer at least one opening or areal recess present. This ensures that also directly superimposed

Bonding layers adhere to each other and to each other very well. As a result, on the one hand, the respective luminous surface is relieved with respect to a tensile stress. On the other hand, the overall arrangement of the multidisciplinary network is strengthened, as the

superimposed connection layers on distributed

Ensure a reliable adhesion. Also delamination phenomena are avoided. At a

Single glass arrangement, but also in laminated glass arrangements, the show through of daylight, for example, is made possible. In order to avoid differences in level of the respective layers with respect to the adjacent, limiting connecting layers, the intermediate spaces, that is to say the surface area of the opening or the areal recess, are filled or designed with a connecting layer. This allows air pockets and larger layers heights Additionally avoid delamination phenomena.

In that the luminous surfaces are connected to at least one power supply and / or an energy store, a reliable and independent operation is ensured, which also the time-shifted operation of the lamp

allows. Advantageously, the energy storage and / or connectable to the power supply, which, if necessary

is switched on and thus the reliable and

uninterrupted operation of the luminaire.

With a further development, there is an energy supply on, on and / or between the glass surfaces. By the

Luminaire is physically coupled with the power supply, no long cable routes and elaborate wiring are required, creating at least part of the needed

Energy is gained at the place of consumption.

Thus, the energy supply m is advantageous in the form of a

Photovoltaic layer disposed on at least one of the outer surfaces of the respective or between the glass sheets and / or plastic discs. Thus, the respective surfaces are efficient for lighting and for

Energy used. During the day is therefore the

Energy storage charged and allows in the darkness zunächi the operation of the lamp to a standstill. Then the switchover takes place to the additional energy supply, which can be the supply network of an energy provider. By the photovoltaic layer between the glass panes and / or

Plastic discs is arranged, this is also protected against the weather as much as possible.

By the respective outer luminous surface and / or

Photovoltaic layer has a protective layer, this is as an outer, not covered by a glass or plastic disc illuminated surface and / or photovoltaic against external influences as protected by weather or destruction.

Advantageously, the luminous area is an LED or OLED luminous surface, whereby a flat and thus laminatable, energy-saving and also flat homogeneous illumination

is possible. In addition, with suitable LED arrangements and OLEDs, disruptive wiring can be avoided.

In a development, at least one of the glass sheets is hardened. This extends the scope of application, as the large-area light can also be used in areas with increased safety requirements. This makes it possible to produce walk-in luminaires that are both roof and path. Furthermore, the accident is taken into account, according to which only small fragments would arise in tempered glass, which thereby of the respective

Connection layer are held.

Advantageously, at least in some areas, one of the

Glass sheets and / or plastic disc one

Surface structure and / or opaque glass, that is translucent, thereby possibly occurring

compensate for inhomogeneous area of the illuminated area. Furthermore, so that the bulbs or their connections are hidden, resulting in a more neutral and aesthetic appearance

contributes. In addition, additional bulbs read laterally arrange the glass panes, which are for example for emergency operation in use. Furthermore, an additional scattering is achieved, which increases the illuminated area.

Advantageously, for a more disc composite under

Use of a suitable for lamination

Bonding layer before lamination on one of

Surfaces of the glass pane and / or plastic sheets with the luminous surface and / or photovoltaic layer on the

Luminous surface and / or photovoltaic layer and / or

Connecting layer and / or surface of this glass pane and / or plastic disc, a further connection layer is at least partially applied and then a second glass plate or plastic disc on the other

Connection layer applied. This method allows an individual construction and leads to a higher

Overall stability of the large-scale light there

More professional network is formed.

Advantageously, a third bonding layer is at least partially applied before lamination to the outer surface of a glass or plastic disc and at least partially on the third bonding layer, a photovoltaic layer and / or a luminous surface and on a fourth bonding layer at least partially and on the fourth bonding layer, a third glass or plastic disc hung up. As a result, the already existing stack-like or sandwich-like structure is expanded, whereby an additional luminous surface, which radiates upwards for example, is integrated or one

Photovoltaic layer is integrated, which the

Energy supply supported. So that we achieve a scalable and individually adaptable structure of the arrangement of the luminaire. By the bonding layer is arranged over the entire surface or partially, the mechanical stability of the arrangement can be according to the requirement

influence .

The procedure provides that the application of a

Connecting layer at least partially on a first cleaned surface of the glass or plastic disc and then applying a luminous surface and / or a photovoltaic layer at least partially on this

Connecting layer takes place. In this case, a single pane with the luminous area and / or photovoltaic layer

fitted. Both surfaces settle on the surface

arrange next to each other. On another glass or plastic disc can be dispensed with first, the

Arrangement is particularly in the use of Plastic discs lighter, has as a single disc, be it glass or plastic but a lower stability.

This simplified method can dispense with the appropriate lamination of the material of the connecting layer on the lavish lamination. The requirement for the used

Link layer is the fulfillment of the required

Adhesive properties against the glass or

Plastic disc and the illuminated area as well

Photovoltaic layer.

In a further development, the application of a further bonding layer additionally takes place at least partially on the second surface of the glass pane or plastic pane and the application of a photovoltaic layer and / or a

Luminous area at least partially on this

Connecting layer, so that the single disc has now experienced on both sides of a coating, which realizes both the lighting and the power supply. Depending on the requirement for mechanical stability, a full-surface or partial arrangement of the connecting layer is provided. Again, it applies accordingly that the used

Connecting layer meets the required adhesive properties against the glass or plastic disk and the light emitting surface and photovoltaic layer.

However, it is also possible that on the one hand a

Bonding layer without laminating and on the other hand a

Lamination is used with lamination, wherein here on the nature of the respective compound layer increased demands that, depending on the order of the coating sides during lamination no detachment of the

Laminier fr eien connecting layer takes place. In this respect, it is preferable initially the side of the glass or

Plastic disc with lamination to edit and

then the side of the glass pane or plastic pane without the required lamination. The method for multi-disc composite discs further sees the application of a connecting layer at least

partially to the respective photovoltaic layer and / or luminous surface of the first and / or second surface of the

Glass pane, applying a glass plate or

Plastic disc on the respective bonding layer, the preparation for lamination, lamination to a

Composite at a laminating temperature of the bonding layer under vacuum and the cooling of the composite and post-processing ago. Thus, the single-disc design can be extended to a composite disc arrangement. Thus, the

increased mechanical strength and weather resistance. By repeating the photovoltaic layer and / or

Luminous surface in the connecting layers and the glass or plastic disc, the structure can be scaled and it can achieve special functional properties.

Advantageously, the luminous area and the photovoltaic layer between two glass panes and / or plastic discs and at least partially between two connecting layers are arranged one above the other, wherein between the luminous area and the photovoltaic layer, a further connection layer at least partially inserted. Thus, a structure is achieved, which between two glass panes and / or

Plastic discs both the light surface and the

Photovoltaic layer includes. The connection layer

between the luminous area and the photovoltaic layer is used depending on the specific embodiment of the luminous area and the

Photovoltaic layer as insulation layer and depending on

Requirement of mechanical stability as connecting connecting layer to increase the strength and stability. For this, the connecting layer can be arranged over the entire surface or partially.

In a further development of the method, the respective luminous surface and / or photovoltaic layer lying on the glass pane or plastic pane and having a surface which can be removed or removed after lamination is used for lamination Separating layer and / or supporting layer is covered. This allows displacements of the respective layers,

Avoid surface changes due to wrinkles and other mechanical influences and adhesions, in particular the connection layer on the vacuum bag, whereby the quality of the process is improved and an improvement of the method is achieved by each with bonding layers and

Luminous surface and / or photovoltaic layer arranged

Glass sheets and / or plastic sheets for lamination in a vacuum bag and a laminating oven or in a

Vacuum oven can be arranged. With this vacuum bag, the surface pressure required for lamination is produced on the composite, the vacuum bag providing a great deal of flexibility in terms of shapes and size. Thus, a considerable simplification of the method is achieved because no special presses or devices for pressing are required. In addition, a uniform pressure is exerted on the composite to be formed by means of the vacuum bag. The vacuum bag further allows the use of a suitable

Laminating furnace without consideration of the furnace pressure.

The inventive large-area lamp 7 from plan or curved or partially curved glass sheets 1 and

Plastic discs 1 includes, depending on application and

If necessary, at least one electrical luminous surface 3 and / or a photovoltaic layer 2. This electrical luminous surface 3 and / or a photovoltaic layer is arranged on at least one of the surfaces of the glass pane 1 or the plastic disc 1, as far as, as shown in Figures la and lb, the large area Lamp 7 is made of a glass plate 1 or a plastic disc 1 as a single disc. Alternatively, the large-area lamp 7 is formed of two or more glass panes 1 as multi-composite disk arrangement. Here are between each two adjacent glass panes. 1 and / or plastic disks 1, the electrical luminous surface 3 and / or a photovoltaic layer 2 is arranged. This from the individual glass plates 1 and / or plastic discs 1 with interposed luminous surfaces 3 and / or a

Photovoltaic layers 2 forms a composite which is used as a large-area luminaire 7.

In areas without luminous area 3 and the photovoltaic layer 2 between two glass panes 1 and / or

Plastic discs 1, at least one connecting layer 4 is present, so that there the glass sheets 1 and / or

Plastic discs 1 form a secure and stable composite as in a per se known multi-composite safety glass. This is illustrated, for example, in FIG. 8, where the luminous surface 3 and the photovoltaic layer 2 are arranged on the respective lateral edges of the large-area luminaire 7.

Furthermore, it is provided that at least one of

outer surfaces of the glass panes 1 and / or

Plastic discs 1 a multi-composite disk assembly also a connection layer 4 is arranged with an electrical light emitting surface 3 and / or a photovoltaic layer.

For independent operation is on, on and / or between the glass sheets 1 and / or plastic disks 1 a

Power supply 5 available. This power supply 5 is preferably a photovoltaic layer 2, although others

Power supplies are possible, which with the

Arrange glass panes 1 and / or plastic panes 1 together.

Depending on the photovoltaic films they can be as

Insert photovoltaic layer 2. So come on

Photovoltaic layer 2 thin-film modules in particular

organic solar films in question. Although the efficiency is only 6-10%, but they also produce electricity with only the slightest sunlight, or almost at high temperatures constantly constant. These organic films range from opaque to semitransparent. The production is environmentally friendly and not material intensive. No solvents are used in the preparation. The films can be processed between laminating films, but also be mounted on the glass pane 1. This would offer the possibility of saving a glass sheet 1, since the film is applied alone on the curvature of the glass sheets 1, as in the

Figures 1 and 4 shown. But also the installation between two sheets of glass 1 and two lamininier films, as shown in Figures 2a, 2c, 3a and 5, is possible.

Furthermore, monocrystalline modules are possible but in the

Compared to organic solar films much more expensive. They have the highest efficiency with 18-20%. Installation on small areas is effective.

But polycrystalline modules are also suitable for installation. They have an efficiency of about 15%.

Figures 3a, 3b and 3c show schematically the structure of a multi-composite pane arrangement as a large-area lamp 7 made of bent laminated glass, as a multi-composite glass with

integrated photovoltaic layer 2 and LED or OLED as

Luminous surface 3. Figure 4 shows the construction of a

Glass composite element, in which an organic solar film as a photovoltaic layer 2 from the outside to the curvature of the

Glass sheet 1 is applied.

This technology makes it possible in the

More composite disk arrangement generated power directly through energy storage 5 to the LED or OLED the luminous surface 3 to pass. To store the energy, as shown in Figure 5, in the holding elements 6 of

More fachverbundscheibenanordnung the large-surface light 7 energy storage 5 installed in the form of batteries. at

As darkness sets in, the system switches on and emits, for example, a light corresponding to the daylight. If there is the possibility of an electrical connection of the glass component locally, energy is switched on from the power grid as a further energy supply 5 as soon as the energy produced via photovoltaic layer 2 and stored in energy storage 5 is used up. This would make it possible to have an area light over the entire night hours available. Especially in remote areas where there is no power grid, lighting would be easily possible during the first hours of the night without having to invest heavily in a public grid.

First, the flat glass panes are as follows

bent and further processed:

1. Gravity bending of the flat glasses or plastics according to a bending method known per se.

The pairs of discs will be two or more discs

superimposed, between the discs becomes one

Release agent given so that the discs can be separated again after the bending process. By self-load of the glass and energy supply over a defined period of time, the desired shape of the flat glass takes place in or above a

Bending shape.

2. Thermal curing according to a method known per se The flat glasses are continuously a kiln

fed there, brought to the necessary processing temperature rever sierende movement of the flat glass in the oven and then in a short time outside the kiln

formed. Important after shaping is the immediately following shock cooling. This is crucial for the formation of the desired tensile or compressive stress in the glass, which makes the tempered safety glass ESG. For a later laminated wheel discs with different radii must be bent to allow subsequent lamination.

3. Chemical hardening of the flat glass after a se known methods

Production analogous to the gravity bending process and

subsequent treatment of the flat glass in an acid bath by ion exchange at the surface, it comes to a

Increase in breaking strength.

For overhead glazing, safety glass is mandatory. With single glass this is hardened and with

More laminated glass come special foils than

Bonding layer used. The safety glass pane required for the over-head glazing is arranged in the composite as the lowest glass pane 1, in order to avoid the risk of falling down dangerous fragments in the event of damage. This is also achieved by the bonding layer 4, since these by the lamination with the glass sheet 1 and thus with the

Splitting is firmly connected.

An essential prerequisite for the later

Lamination process is the absolute fit of the

curved discs with each other. The respective outer pane has a different bending radius than the inner one

Slice in the composite.

Since the plastic discs 1 have a different bending temperature than the glass sheets 1, the bending of these takes place separately based on the presentation of a glass sheet 1 for the

later composite or by means of a bending mold.

A flow for a concrete embodiment of a

Mehrfachverbundscheibenanordnung show the following

Process steps of lamination and incorporation of the photovoltaic layer, as well as the LED and OLED luminous surfaces. Although of glass panes 1 or flat glass panes 1

is spoken, these steps are as well on

Plastic discs 1 transferable:

- Good cleaning of the flat glass panes 1, which is flat or curved. This cleaning has to be done particularly well after the bending process. It does not matter when after bending or after the upstream or

preparatory position of manufacture of the glass sheet 1, the cleaning of this glass sheet 1 takes place. The

Glass panes 1 must be clean before the next steps for the required adhesion, whether without laminating or with lamination.

- Applying a first PV-WR film as a bonding layer on the glass pane. 1

- Applying the photovoltaic layer 2 on the first PV-WR film

Applying a second PV-WR film as

Connecting layer 4 on the photovoltaic layer

- Application of the second, also well cleaned

Glass pane 1, which is compatible with the first glass sheet 1 plan or bent

- Applying a third PV-WR film as

Connecting layer 4 on the second glass pane. 1

- Applying the LED or OLED light surface 3

- Make sure that the power cables of the solar foil and the LED or OLED lighting area 3 are exposed

- Applying the fourth PV-WR film as a bonding layer 4 to the respective luminous surface variant

- In preparation for the lamination, several tapes are set at the edge of the disk package for adjustment.

This leads to a stabilization and simplification in the procedure, since shifts are at least reduced and thus to a higher quality of the

Lamination.

- the entire perimeter glass edges are taped

- The disc composite is placed in a special vacuum bag t

- About special vacuum valves / leads u. Vacuum pump, the vacuum is applied and in a special

Execution of the disk package is about 3-5 hours in the Oven. It is absolutely necessary to ensure that there is an absolutely homogeneous temperature field in the laminating oven

is set and held.

- After leaving the disc composite from the

may not be heat resistant immediately.

Is a lamination of each outside on the glass sheets 1 or plastic plates 1 with the connecting layer 4th

lying photovoltaic layer 2 and / or luminous surface 3 is also possible or necessary, it is provided that for the lamination, the respective outer, the conclusion of the stack or composite forming photovoltaic layer 2 and / or luminous surface 3 is covered with a release layer. The release layer, which is removed after lamination, ensures that the vacuum bag is not at the

optionally exposed bonding layer 4 sticks and this is destroyed when removing the vacuum bag. On the other hand, influences of the vacuum bag on the respective photovoltaic layer 2 and / or luminous surface 3 are minimized. In order to further reduce or largely exclude these influences of the vacuum bag, which may be caused by wrinkles upon application of the vacuum, alternatively or additionally the outer arrangement of the photovoltaic layer 2 and / or luminous surface 3 is covered with a supporting layer. The separating layer and the supporting layer are each designed so that they are removable or removable again after lamination, without destroying the composite and in particular the bonding layer 4, provided that they are connected to the separating layer and

Support layer comes into contact.

It is further provided that the connection layer 4 is already part of or at least one side already with the respective photovoltaic layer 2 and / or luminous surface 3 or brought together. Depending on the type of

Connection layer 4 is to be seen in a simplification, since already these layers carefully prepared outside the process and are arranged as a small intermediate compound easily on the respective glass pane 1.

Is outboard, so, as in the figures la and lb

illustrated, not protected by a glass sheet 1, a photovoltaic layer 2 and / or luminous surface 3, it is recommended that this photovoltaic layer 2 and / or luminous surface 3 have a protective layer to be less sensitive to the weather.

As already stated above, the invention allows the photovoltaic layer 2 and the luminous area 3 to be common

next to each other or one above the other and each individually, so for example, only the luminous surface 3 next to each other or one above the other and also staggered or arranged.

Important here are on the one hand sufficient adhesion of the photovoltaic layer 2 and the luminous surface 3 to the glass pane 1 or plastic disc 1, which as described on the bonding layer 4, a lamination foil such as a film of ethylene vinyl acetate EVA is achieved.

On the other hand, in the case of an overlapping or one Stack-like arrangement one above the other adhesion and electrical and mechanical contact protection

important to each other. This adhesion and this protection is achieved by means of the bonding layer 4, wherein, depending on the thickness of the photovoltaic layer 2 and the luminous surface 3, the thickness of the bonding layer 4 is adjusted or that the bonding layer 4 is applied in multiple layers. Thus, FIG. 7 shows a multilayer structure in which a photovoltaic layer 2 is arranged upwards and a luminous surface 3 is directed downwards, these layers being insulated from one another by a connecting layer 4 and also in each case one connecting layer 4 to the limiting one

Glass pane 1 or plastic disc 1 is present.

Such a multilayer arrangement of the connecting layer 4 is also provided, for example, if according to the invention in the luminous area 3 and photovoltaic layer 2 a

Opening 9 is present. An opening 9 is, for example, as shown in Figure 6, provided in the middle of a large-area lamp 7, wherein at the edge, for example, facing up a photovoltaic layer 2 and facing down a luminous surface 3 is arranged and through the aperture in the middle of daylight unhindered can penetrate. Corresponding openings 9 or

Recesses 9 can also be arranged round or str eifendförmig. In this case, if the thicknesses of the luminous area 3 and photovoltaic layer 2 exceed a maximum, it is necessary that a connecting layer 4 is introduced into this opening 9 or recess 9, which at least corresponds to the area of the opening 9 or recess 9. In order for opening 9 or recess 9 is filled and it can be an optionally formed cavity safely avoided.

8 shows an arrangement of a large-area luminaire 7, wherein it has a circular-arc-shaped, that is to say curved, region and a plane, ie, not curved, region. The plane area joins the curved area immediately and extends this tangentially. In a specific exemplary embodiment, the luminous area 3 and the photovoltaic layer 2 are arranged only in the plane area of the glass panes 1 and plastic panes 1, these being arranged individually with the connecting layers 4 between the panes

Glass sheets 1 and plastic discs 1 are arranged.

Also provided is a non-illustrated embodiment of a large-area luminaire 7, in which the luminous area 3 and the photovoltaic layer 2 by at least one

Connecting layer 4 separated together in the planning area an otherwise curved between two glass panes 1 or between a glass pane 1 and a plastic disc 1 or

between two plastic discs 1 each with the

Connecting layers 4 are arranged.

Likewise, an unillustrated embodiment of a

large-area lamp 7 is provided, in which a suitable luminous surface 3 in a curved region and the

Photovoltaic layer 2 in the plan, not bent portion of the glass pane 1 and / or plastic disc 1 is arranged. In this case, the luminous surface 3 and the photovoltaic layer 2 with the connecting layers 4 are arranged between two glass pane 1 and / or plastic pane 1, wherein the respective intended use prescribes the selection of the respective type of pane.

Following a particular embodiment, not shown, one of the glass panes 1 or plastic discs 1 has a surface structure, which achieves a special appearance and can also cause light scattering. Thus, translucent glass panes 1 and plastic discs 1 can also be used, since they cover any required inclusions in addition to a homogeneous luminous surface.

After the lamination or the application of the outer layer is made of bonding layer 4 and photovoltaic layer s or luminous surface 3, the final assembly of

More professional safety glass with integrated solar foil and LED resp. OLED panel in holding elements 6 or 6 frame performed. The laminated glass elements are in the

Retaining elements 6 or frame 6 inserted Figure 5. In these holding elements 6 or frame 6, which pipes or

Box profiles are, are energy storage 5 in the form of batteries. The cables as electrical connection 8 of the

Solar films of the photovoltaic layer 2 become the

Energy storage 5 out. The energy produced during the day is absorbed in the energy store 5. From the energy storage 5, an electrical connection 8 leads to the LED or OLED panels of the luminous area 3. When darkness sets in, the stored energy of the energy store 5 is available to the LED or OLED of the luminous area 5 and is released by the latter as area light. Is also a power grid for

Available, this is integrated with, so after the

Unloading the energy storage 5, energy can be switched from the mains.

Possible applications are any areas where a good surface light is required:

- Lichthofüberglasungen

- Front door glazings

- Gate entrances

- Bus stations

- Bus stops

- bridge glazing etc.

The use of bent multiple glazing elements is statically optimal due to the curvature of the disk packs and even for larger overvoltages e.g. Bridges implementable.

Wherever there is no electricity supply available locally, such as remote areas or countries in the third world, energy is available for lighting in at least a limited period of time. Compilation of the reference numerals
