Independent claims are also included for the following: (a) an element as above having a light diode strip; (b) an element as above have a long after life light strip; and (c) a production process for the above elements.

Description

object The invention is a glass element with a light frame based longitudinal light elements in the form of LED strips and / or EL strips and / or long afterglow strips or combinations of these light elements.

Usually are two or more of the same or in modern glass constructions unevenly spaced glass panes made of flat glass, also as float glass designated, with a thickness of a few mm to about 21 mm, typically 4 mm thick and 16 mm apart. The embodiments can according to the properties for the Heat protection, sun protection, visual and design requirements, sound insulation, fire protection, people and property protection and the like. Combinations of the mentioned types can be used.

A common flat glass dimension is exemplary 6.00 x 3.21 Meters and this turns the panes for typical multi-pane insulating glass structures manufactured. The edge bond seals them hermetically interspaces manufactured that commonly filled with an inert gas become. The gas pressure becomes the barometric Air pressure set at the location and at the time of production. It So there is a balance between at the time of production the pressure in the glazing unit and the external barometric pressure in the production environment.

Next these double, triple or multiple insulating glass structures made of simple float glass, can such multi-pane insulating glass structures are formed from panes that have a coating on one or both sides and thus the reflection and / or transmission and / or optical Training in desired Wavelength ranges of the light. The individual disks can be preloaded or colored accomplished be made or so-called safety glass.

at Safety glass or safety insulating glass is originally for the automotive industry for the Glasses developed in vehicle glazing and today such, Sandwich-like safety glass elements increasingly used in building technology used. in principle is between single-pane safety glass and laminated safety glass distinguished and it can be in In principle, both types of the present invention are used.

In the US 5,386,347 describes an illuminated transparent or semitransparent optical medium in the form of an acrylic plate, two fluorescent tubes introducing the light into the acrylic plate on two opposite sides.

By various surface designs or through several layered plates there is a light deflection to one side.

This Technology has chosen the backlighting of flat screens and the use very thinner Cold cathode ray tubes as a very useful lighting especially with color emission highlighted in white. In the present invention, however, no fluorescent tubes, respectively Cold cathode ray tubes used.

In the EP 0 516 514 an illuminated display board is described. The lighting is carried out with light-emitting electronic components arranged in a distributed manner. The light sources are connected to a battery and an electronic control. However, a glass element with a light frame is missing.

By doing DE 29603225 U1 describes a luminous disc in which one or more edges of the pane are provided with illuminants, the light of which is introduced into the pane via the edge. Light-emitting diodes interconnected in groups are mentioned as illuminants.

In the EP 0 821 820 B1 describes a lighting device with a body made of transparent material, for example made of acrylic glass, and one or more ribbon-shaped light sources. Band-shaped printed circuit boards are mentioned as band-shaped light sources, on which light-emitting diodes in SMD technology are applied in a dense, compact sequence. Furthermore, band-shaped light sources made of electroluminescent film, which continuously generate light over their length, are shown. However, no longitudinal light element in a profile frame with a glass element is described there.

In the US 5,369,553 describes an illuminated display board made of light-conducting material in the form of acrylic glass. A light source on the lower side of the acrylic plate introduces light and a graphic design is created with a laser in the acrylic plate. In this invention, too, no longitudinal light element is shown in a profile frame with a glass element.

The The invention is therefore based on the object of a lighting element to train so that it is manufactured more cheaply and with better light output can be used.

A preferred embodiment of the invention relates to a glass element with a light frame with at least one longitudinal light element in the form of an LED strip and / or EL strip and / or long afterglow strip.

The The invention also provides combinations of these light elements for use as a decorative element and / or lighting element in interiors and / or exterior facades of buildings, in furnishings and in vehicles and in the advertising industry and the like applications in front.

The The invention accordingly relates to Glass element with a light frame with at least one longitudinal one Light element in the form of an LED strip and / or EL strip and / or long afterglow strip.

On Typical safety glass construction consists of two float glass or cast glass panes with a thin inner layer respectively several thin Inner layers with a total thickness of a few 0.1 mm and typically 0.4 mm or 0.8 mm thickness made of poly vinyl butyral (PVB) or Polyurethane (PU) or polyvinylchloride (PVC) or the like Polymers or in a more cast form with preference casting resins based on polyester or polyacrylic with appropriate refractive index greater than 1 and less than 2, typically in the range of 1.5 and / or in combination made of glass panes in combination with panes made of transparent plastic.

At least according to the invention a longitudinal light element preferably on the inside on the frame attached, which serves as a spacer and in the form of a profile is made. The attachment can be done with self-adhesive tape or Hot melt adhesive system or by snapping or screwing or crimping or pushing in and the like fastening methods.

there must reflect the different expansion coefficients of the frame and the various lighting elements in operation. Usual frames are made of aluminum or various aluminum alloys extruded. in principle can however, plastics are also used. In special versions can also stainless steel frames or frames made of simple profiled iron sheets can be used with an appropriate coating. Using of metallic frames represent the good heat dissipation property and the good water vapor barrier function an advantage when using Light elements based on electroluminescent foils and long afterglow layers represents.

A first embodiment of the invention is described in the form of an EL strip:
Longitudinal electroluminescent strips (EL strips) are preferably used with widths from 6.35 mm to 609.6 mm and a typical strip thickness of approximately 0.3 mm with lengths of 90 to 100 meters.

For installation In typical insulating glass structures, strip widths of 12.7 mm and 25.4 mm very good. The operation takes place via so-called EL inverters. This is usually done DC voltages of some 1.2 to 9 or 12 or 24 or 48 volts in AC voltages from a few 100 volts to over 200 volts and frequencies from a few 50 Hz to a few kHz, typically 400 to 2,000 Hz. Such inverters can now in the interior of the double glazing, in the frame profile or outside to be ordered.

Next this flat EL strips can in principle also longitudinal round EL elements are used.

The essential disadvantage of such EL elements in conventional Use is the short half-life of a few 1,000 to 2,500 and 3,000 hours. The decrease in brightness is called the half-life by half understood the initial brightness.

Also if usual EL films do not have a direct end of life, so the emission brightness takes over Degradation of the zinc sulfide and mostly microencapsulated electroluminophores continuously. The degradation usually only occurs during operation and is very much connected by high humidity with increased Temperature accelerated.

Usual polymers Laminates show when increasing the temperature a sharp increase the water vapor permeability on. For typical insulating glass structures must however lifespan values of some 20 years at relatively high Temperatures are guaranteed.

Offer according to the invention insulating glass structures with a preferably almost water vapor-free Interior with the inert gas, such as argon or krypton or the like gas mixtures is filled. This is a water vapor barrier for EL elements.

In addition, a drying agent, or a so-called molecular sieve, is usually added to the cavity of the frame profile and the frame profile is provided with openings to the interior, so that water vapor residues are bound in the interior of an insulating glass structure. The frame is also encircled with the glass panes with a polymeric mass based on polyvinyl butiral (PVB), silicone, poly sealed urethane (PU), polyethersulfone (PES), polysulfone (PSU) and the like.

By the arrangement of such EL strips inside an insulating glass structure can with careful execution the electrical connections much longer Half-lives can be achieved. In addition, when using conventional float glasses and / or Pouring glasses one Given UV-B filtering, which leads to a reduction in the aging of the leads zinc sulfide electroluminophores and thus also outdoor applications extends the general lifespan, or increased the emission brightness over the time axis.

A second embodiment of the invention is described in the form of an LED strip:
According to the invention, so-called LED strips are used as light elements in frames for glass elements. In principle, all types of LED elements can be used to produce a longitudinal LED strip. In addition to conventional LED elements with radial connections and in plastic housings as well as in metal housings, elements conventionally mounted or wired on circuit board substrates can also be used.

Further become surface-mountable LEDs, so-called SMD (Surface Mount Device) or SMT (Surface Mount Technology) LED elements or electroluminescent semiconductor elements in direct assembly on wiring substrates, i.e. unhoused LEDs for the so-called chip-on-board technology used.

at the COB method as substrates both flexible or rigid or semi-flexible circuit board materials be used. Likewise, so-called lead frames, i.e. metallic ones Stamped parts in strip form, with lens elements here using in-mold injection molding and holding elements are executed.

Common SMT LED components have a light intensity of typically 20 mA and about 2 volts DC 5 to 20 mCd. The light intensity is the luminous flux related to the solid angle and there are SMT LEDs with relatively large solid angles typically used from 100 to 140 °. Such surface mountable Components one component height from 2.1 mm to 0.8 mm and are already available in a special design with a height of 0.55 mm are available.

High-performance LEDs with a beam solid angle offer from some 5 to 30 ° already light intensities in the 25,000 mCd range and in pulse mode also beyond. At such light intensities represents the exhaustion the heat loss and the type of contacting is already a major problem. For the Use the usual Long lifespan of some 10,000 to 100,000 hours, this must problem solved his. In the present case, the frame profiles are available for dissipating the heat which are preferably made of aluminum. In such cases, the Wiring substrates with good thermal conductivity on the frame profile be attached. It can also the wiring substrates made of the appropriate aluminum circuit board material are manufactured.

For a number of applications are moreover not just the usual red and green and yellow and blue signal colors of interest but it will white Light preferred. Such LEDs are common operated in the blue area. Through color-converting lens body a white one Emission generated. There are inorganic admixtures in the Polymer matrix of the lens body used and thus extremely long-term stable emission spectra achieved without color shifts.

In addition there is still the possibility the use of so-called R-G-B LEDs, i.e. LEDs with 4 electrical connection elements and the emission colors red - green - blue. With such LED elements there is electronic shading consuming, it can however, all mixed colors electronically generated and readjusted. It can too depending on the design of the electronic control different Color effects generated in chronological order and, if necessary, by means of Sensors are controlled.

It become LED strips on double-sided, flexible circuit boards with surface-mounted SMD LEDs and other components based on a roll-to-roll assembly and contacting process and manufactured in multiple uses. Usual roll lengths are 100 or 200 meters and above. A plurality of LED elements are preferably connected in series and can then for example with a supply voltage of 12 or 24 volts Direct current of such a unit can be operated.

exemplary an LED strip from Osram Opto Semiconductors with the Type designation LINEARlight flex OS-LM11A used. Such one LED strip comes with a total length of 8.4 m and a basic size of 10 LED's with 140 mm Length at a height delivered less than 3 mm and a strip width of 10 mm. The backside this LED strip is self-adhesive.

The power is supplied with 24 volts DC, nominally the smallest unit to be operated with 10 LEDs each with a length of 140 mm required between 40 and 50 mA depending on the emission color. The nominal light intensity is from 95 mcd (blue) to 305 mcd (white) and 730 mcd (yellow). The power consumption of the 10 pieces of LEDs is 0.96 to 1.2 watts or 6.9 to 8.6 watts per running meter. The beam angle of these LED components is 120 °.

The Operation of, for example, 1 to 10 LED running meters can therefore be very good through inexpensive and simple power supplies and there is no double insulation requirement.

The Beam angle can be adapted to the respective application and it can with special lens formations and / or attachments also asymmetrical radiation characteristics be achieved. It can also be advantageous to use a diffuser install. In the present case, this can be done in the interior of the insulating glass element very simple thanks to transparent elements with good light-conducting and scattering surface can be achieved.

As Substrate for such LED strips can single sided and double sided flexible printed circuit boards based on for example polyamides (PI) and / or polyethylene terephthalate (PET) or poly ethylene glycol terephthalate (short name PETP or PET) and / or polyether sulfone (PES) and / or polyetherimide (PEI) and / or polyether ether ketone (PEEK) and / or aramid and / or fiber-containing flexible films and the like can be used. This creates thin copper foils and / or aluminum foils applied and according to the wiring requirements structured.

This can be done by the usual methods in the PCB industry and can do it both phototechnical and screen printing masking processes followed by etching become. About that structuring by laser beams is also provided.

As a third embodiment, light elements made from long-afterglow substances in the form of strips are described:
Inexpensive, zinc sulfide, long afterglow pigments are used. These are embedded in a polymer matrix and applied using conventional coating technologies. The use in the form of a self-adhesive strip has the disadvantage of a relatively short persistence and the low resistance to UV radiation and water vapor.

in the The present case is the arrangement in the interior of an insulating glass element neither a water vapor exposure nor a high UV exposure. By usual Glass panes in the form of float glass or cast glass are at least the UV-B radiation greatly reduced and possibly by an additional Coating also reduced UV-A radiation.

In However, the present invention is particularly rare Soil doped aluminates and silicates and the like inorganic Pigments used and / or a mixture of conventional zinc sulfide Phosphors and, for example, strontium aluminate pigments.

usual, Pigments based on strontium aluminates are very fine-grained in Sizes of a few micrometers, typically 10 micrometers to coarse-grained pigments of typically 50 micron dimensions available. They show long afterglow times from above 20 hours up to the 50 hour range and emit in one typical wavelength range from about 400 nm to 640 nm, typically the yellow-green area are best perceived by the human eye at around 520 nm can.

there not only the excitation in the UV range can be used. There can already be artificial ones Illuminations, for example, based on fluorescent tubes, respectively other lamps cause a charge. Usually the suggestion in the range of 200 to 450 nm with good efficiency and reaches a typical maximum at 380 nm.

The persistence of escape route markings is usually measured in accordance with DIN 67510 and other standards. The darkly adapted eye still perceives luminance values of approximately 0.01 mcd / m ² . In DIN 67510, 0.3 mcd / m ^{2 is recorded} as the value that is used for the afterglow power of a system for comparison purposes and must be over 5.7 hours. Long afterglow systems according to DIN 67510 must also have a luminance of greater than 2.8 mcd / m ² after 60 minutes in dark surroundings.

Next the customary available Strontium aluminates are silicates based on rare earth doped Long afterglow pigments due to their high temperature resistance up to the range of 600 to 800 ° C interesting, but such pigments then have shorter afterglow times.

All in the documentation, including the information and features disclosed in the summary, in particular the spatial training shown in the drawings claimed as essential to the invention, insofar as they are used individually or in Combination versus the state of the art are new.

31 an arrangement with a glass element ( 1 ) with light elements ( 11 . 23 . 24 . 29 ) in the interior ( 18 ). One of the coatings ( 6 . 7 . 8th . 9 ) can be mirrored or with a sun protection effect and can be a light element ( 11 . 23 . 24 . 29 ) can be arranged in a hidden manner and such special night lighting effects are made possible.

In 1 an arrangement is shown in a sectional view, with an EL strip ( 11 . 23 ) on a standard profile frame ( 4 ) is attached.

This arrangement is a typical insulating glass construction. Two glass elements ( 2 . 3 ) made of float glass or cast glass or laminated safety glass using a spacer ( 4 ) in the form of a profile frame and further a seal ( 5 ) composed of, for example, polyvinyl butiral (PVB), silicone, polyurethane (PU), polyether sulfones (PES), polysulfones (PSU) and the like.

This creates a hermetically sealed interior ( 18 ), which is usually filled with an inert gas. The gas pressure is set according to the barometric air pressure at the location and at the time of production. At the time of production, there is a balance between the pressure in the glazing unit and the external barometric pressure in the production environment.

The interior of the frame profile ( 4 ) with desiccant ( 10 ) filled and the frame profile ( 4 ) becomes the interior ( 18 ) with breakthroughs ( 17 ) Mistake. The interior ( 18 ) kept free of water vapor, which is the reason for the lifespan of common EL strips ( 11 . 23 ) in use in such durable glass elements ( 1 ) is very essential.

The electrical connection ( 12 ) of the light element ( 11 . 23 ) is carried out in such a way that the corresponding lines ( 23 ) through the frame profile ( 4 ) and by means of the seal ( 5 ) be sealed. In order to achieve a correspondingly long-lasting seal, lines ( 23 ) are used that do not exchange gas with the interior ( 18 ), such as enamelled copper wires and the like.

For the operation of the EL strips ( 23 ) so-called EL inverters or converters are required. Typically, a DC low voltage is converted to an AC of a few 100 to 200 volts and above and frequencies from 50 Hz to 2,000 Hz and above to outside the listening range. Depending on the version, such electronic modules can be installed in the interior ( 18 ) or inside the frame profile ( 4 ) or arranged outside.

The light emission ( 15 ) takes place from the surface of the EL strips ( 11 . 23 ). With an appropriate coating ( 6 . 7 . 8th . 9 ) the glasses ( 1 . 2 ) can both refractive effects of the emission radiation ( 15 ), as well as mirrored effects. Depending on the choice of the mirror layer ( 6 . 7 . 8th . 9 ) an EL strip can also be hidden directly in the interior ( 18 ) on one of the surfaces of the glasses ( 1 . 2 ) are attached.

The attachment of the EL strips ( 11 . 23 ) on the inside of the frame profile ( 4 ) can with a Fasteners ( 13 ) respectively. Self-adhesive systems or cold adhesive systems or hot-melt adhesive systems and the like fastening means can be used for this purpose. The EL strip can also be arranged all around or in pieces.

In 2 an arrangement is shown in a sectional view, with an EL strip ( 11 . 23 ) on a profile frame ( 4 ) with a molded reflector ( 14 ) is attached. The arrangement of the reflector elements ( 14 ) the light emission ( 15 ) the EL strip ( 11 . 23 ) in a desired direction by reflected light ( 16 ) are performed. All other details apply analogously to 1 ,

In 3 a schematic representation of an arrangement is shown in a sectional view, with an LED strip ( 11 . 24 ) on a standard profile frame ( 4 ) is arranged. The light emission ( 15 ) the LED ( 25 ) can on the one hand through the boundary layers of the glasses ( 1 . 2 ) and / or through the coatings ( 6 . 7 . 8th . 9 ) distracted or reflected ( 16 . 16 ' ) become.

When using LED strips ( 24 ) usually several LED components ( 25 ) connected in series, whereby the voltage supply can be brought to typically 12 or 24 or 48 volts and the necessary operating current can be reduced. The energy supply is very simple using electrical connection cables ( 12 ) by the frame profile ( 4 ) are guided and by means of the seal ( 5 ) are sealed. The connecting lines ( 12 ) must also be protected against gas diffusion, which is well fulfilled, for example, by enamelled copper wires.

The at least one LED strip can be as in 1 described by a variety of fastening methods using a fastener ( 13 ) on the inside of the profile frame ( 4 ) are attached. For high-performance LED strips ( 24 ) the heat dissipation of the frame profiles ( 4 ) be used. Aluminum is particularly suitable as a frame material. In such cases, the LED strips can be contacted with fasteners that conduct heat well ( 13 ) respectively. All other details apply analogously to 1 ,

In 4 a schematic representation of an arrangement is shown in a sectional view, an LED strip (left and right in this embodiment) 11 . 24 ) on a profile frame ( 4 ) is arranged with a reflector ( 14 ) is provided. This means that emitted light ( 15 ) reflected in a desired direction ( 16 ) become. All other details apply analogously to 1 and 3 ,

In 5 a schematic representation of an arrangement is shown in a sectional view, only the frame ( 4 ) inside with an EL strip ( 11 . 23 ) is executed. The attachment of the EL strips ( 23 ) using fasteners ( 13 ) can as in 1 described using a wide variety of methods.

A commercial EL strip ( 23 ) can be produced in very long lengths of typically 90 or 100 meters and above. Aluminum foils are usually separated using various processes and this results in EL split electrodes ( 19 ), which due to their good conductivity hardly cause a voltage drop over very long distances and therefore the operation of such EL strips ( 23 ) over very long lengths.

On the EL split electrodes ( 19 ) an insulation layer or a dielectric layer is given and then a largely transparent polymer matrix with zinc sulfide electroluminophores ( 20 ) of typically a few 15 to 50 micron pigments and a transparent cover electrode ( 21 ). Metal-oxidic and / or metal-nitridic microencapsulated electroluminophores ( 20 ) and thus the so-called half-life can be increased to a few 2,000 hours.

The lamination of the EL strips ( 23 ) because, despite the microencapsulation of the electroluminophores ( 20 ) are subject to severe degradation during operation at elevated temperature and the influence of moisture. The split electrodes made of aluminum form an excellent water vapor barrier. The transparent or largely transparent cover electrode ( 21 ) made of preferably indium tin oxides (ITO) or non-ITO or of electrically conductive and transparent polymers, does not offer good water vapor barrier properties at elevated temperature in conjunction with conventional transparent cover layers made of PET, for example.

In the present invention, however, these properties which limit the service life do not play a role, since in the interior ( 18 ) anyway the water vapor content is extremely low.

In 6 becomes a typical EL strip ( 23 ) shown in top view. The EL emission ( 15 ) is only in the area of the split electrode ( 19 ) causes. The electrical connections of the two split electrodes ( 19 ) is usually done by crimp connections ( 22 ).

In 7 is analogous to 5 a schematic representation of an arrangement in a sectional view with an LED strip ( 24 ) ge shows. In contrast to the installation of an EL strip ( 23 ) when using high-performance LED strips ( 24 ) good heat transfer to the frame profile ( 4 ) is respected and accordingly the fastener ( 13 ) selected.

In 8th a typical LED strip ( 24 ) shown in top view. Such an LED strip can be obtained from Osram Opto Semiconductors GmbH, D-93049 Regensburg, Germany with the type designation LINEARlight flex OS-LM11A. Such an LED strip is, for example, with a total length of 8.4 m and a basic size of 10 LEDs ( 25 ) as the smallest LED unit ( 28 ) with a length of 140 mm and a height of less than 3 mm and a strip width of 10 mm in the form of a flexible substrate ( 26 ) delivered. Such 140 mm long units can be easily separated from the roll using scissors. The LED grid dimension ( 27 ) is 14 mm in this version. The back of these LED strips is self-adhesive. The power is supplied by 24 volts DC ( 12 ). Nominally, the smallest unit of 10 LEDs with a length of 140 mm, depending on the emission color, needs between 40 and 50 mA to achieve a luminous intensity of 95 mcd (blue) to 305 mcd (white) and 730 mcd (yellow). The power consumption of such units of 10 LEDs is 0.96 to 1.2 watts or 6.9 to 8.6 watts per linear meter. The beam angle of these LED components is 120 °.

In 9 a schematic representation of an arrangement is shown in a sectional view, only the frame ( 4 ) with a long afterglow layer ( 29 ) is pictured. Since aluminum is used as the material for the frame profile ( 4 ) reflects the surface very well, with this inexpensive arrangement the inside of the frame profile ( 4 ) with a long afterglow layer ( 29 ) made of a well-adhering and transparent polymer matrix ( 31 ) with embedded long-afterglow pigments ( 30 ) can be coated. The coating can be carried out by means of brushing, knife coating, dipping, spraying, screen printing and the like coating methods. In most of these processes, the frame openings ( 17 ) free. However, a subsequent production of these frame openings ( 17 ) respectively.
