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 lighting elements.

Usually become two or more alike in modern glass constructions Non-uniformly spaced glass panes of flat glass, also as float glass designated, with a thickness of a few mm to about 21 mm, typically of 4 mm thickness and 16 mm distance used. The embodiments can according to the properties for the Thermal insulation, sun protection, visual and design Requirements, sound insulation, fire protection, persons and property protection and the like. It can also be combinations of the types mentioned.

A usual Flat glass dimension is exemplarily 6.00 × 3.21 Meters and these are the panes for typical multi-pane insulating glass structures produced. By the edge bond are hermetically sealed Intermediate spaces usually made by a noble gas can be filled. The gas pressure will be corresponding the barometric pressure at the place and time of production set. So there is a balance at the time of production between the pressure in the glazing unit and the outer barometric Printing in the production environment.

Next these double, triple or even multiple insulating glass structures made of simple float glass, can also such multi-pane insulating glass structures be formed from slices on one or both sides have a coating and so the reflection and / or transmission and / or optical training in desired wavelength ranges of the light. The individual slices can be carried out biased or through-dyed or be formed of so-called safety glass.

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

In the US 5,386,347 For example, an illuminated transparent or semitransparent optical medium in the form of an acrylic plate is described wherein two fluorescent tubes introduce the light into the acrylic plate on two opposite sides.

By various surface designs or by several layered plates becomes a light deflection to one side causes.

These Technique has been chosen for the backlighting of flat screens and the use of very thin cold cathode ray tubes as a very useful lighting, especially with the color emission white exposed. In the present invention however, no fluorescent tubes or cold cathode ray tubes used.

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

By doing DE 296 03 225 U1 a light-emitting panel is described in which one or more disc edges are provided with lighting means whose light is introduced via the edge in the disc. As lighting means group-wise interconnected light-emitting diodes are called.

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

In the US 5,369,553 An illuminated display panel made of light-conducting material in the form of acrylic glass is described. A light source on the lower side of the acrylic plate causes light to be introduced and a graphic design is made with laser in the acrylic plate. Also in this invention, no longitudinal light element is shown in a profile frame with a glass element.

Of the The invention is therefore based on the object, a luminous element so educate that it is made more cost effective and can be used with better light output.

A preferred embodiment of the invention refers to a glass element having 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 Invention also sees combinations of these light elements for the 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 Invention relates to the according to a glass element with a light frame having at least one longitudinal light element in the form of an LED strip and / or EL strip and / or long afterglow strip.

One typical safety glass construction consists of two float glass or cast glass slices with a thin inner layer respectively several thin inner layers of a total thickness of a few 0.1 mm and typically 0.4 mm or 0.8 mm thickness of polyvinyl butyral (PVB) or polyurethanes (PU) or polyvinyl chlorides (PVC) or the like Polymers or in cast form with preferred Casting resins based on polyester or polyacrylic with corresponding refractive indices greater than 1 and less than 2, typically in the range of 1.5 and / or in the combination of glass panes in combination with discs of transparent plastic.

According to the invention at least one longitudinal light element preferably on the inside mounted on the frame, which serves as a spacer and in shape a profile is made. The attachment can be done with self-adhesive tape or hot melt adhesive system or by means of snap or Screwing or crimping or insertion and the like attachment methods respectively.

there must be based on the different coefficients of expansion of the frame and the various lighting elements are taken into account during operation. usual Frames are made of aluminum or various aluminum alloys extruded. In principle, however, plastics can also be used Find. In special versions can also Stainless steel frame or frame made of simple profiled iron sheets be used with an appropriate coating. Using of metallic frames provide the good heat dissipation property and the good water vapor barrier function has an advantage in the use of Light elements based on electroluminescent and long-lasting Layers

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

For the installation in typical insulating glass structures strip widths are suitable of 12.7 mm and 25.4 mm very good. Operation is via so-called EL inverter. These are usually DC voltages from 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 of some 50 Hz to a few kHz, typically 400 to 2,000 Hz, transformed. Such inverters can now in the interior of the insulating glazing, be arranged in the frame profile or outside.

Next This flat EL strip can basically also longitudinal round EL elements are used.

Of the significant disadvantage of such EL elements in conventional Use is the short half-life of some 1,000 to 2,500 and 3,000 hours. Below half-life is the decrease in brightness understood by half the initial brightness.

Also if standard EL films have no direct end of life, Thus, the emission brightness decreases by degradation of the zinc sulfidic and usually microencapsulated electroluminophores continuously. Degradation usually occurs only during operation and is very much connected by a high humidity accelerated with elevated temperature.

usual polymeric laminates have a temperature increase strong increase in water vapor permeability on. For typical insulating glass structures must however lifetime values of some 20 years at relatively high Temperatures are guaranteed.

Offer according to the invention insulated glass structures with a preferably approximately steam-free interior, which with inert gas, for example Filled argon or krypton or the like gas mixtures is. This is a water vapor barrier for EL elements.

In addition, usually a desiccant, or a so-called molecular sieve, placed in 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 a Isolierglasaufbaues. The frame is also circulating with the glass sheets with a polymeric composition based on polyvinyl butyral (PVB), silicone, poly urethane (PU), polyethersulfones (PES), polysulfones (PSU) and the like.

By the arrangement of such EL strips in the interior of a Isolierglasaufbaues can with careful execution the electrical connections much longer Half-lives can be achieved. In addition, when using of common float glasses and / or casting glasses given a UV-B filtering, resulting in a reduction in the aging of the zinc sulfide electroluminophores and thus also in outdoor applications the general life extended, or the emission brightness over the time axis elevated.

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 a light element 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, conventionally mounted or wired elements can also be used on printed circuit board substrates.

Further become surface-mountable LEDs, so-called SMD (Surface Mount Device) or SMT (Surface Mount Technology) LED elements or electroluminescent Semiconductor elements in direct mounting on wiring substrates, So unexpanded LEDs for the so-called chip-on-board technology used.

at The COB method can be used as substrates both flexible or rigid or semi-flexible printed circuit board materials are used. Likewise, so-called lead frames, ie metallic stampings in strip form, here by means of in-mold injection lens elements and holding elements are executed.

usual SMT LED devices typically have 20 mA and about 2 volts DC a light intensity of 5 to 20 mCd. The light intensity is the luminous flux related to the solid angle and it will be SMT LED's used with relatively large solid angles of typically 100 to 140 °. Thus, such surface mount components a component height of 2.1 mm to 0.8 mm and are already in a special design with a height of 0.55 mm available.

High-performance LEDs offer with a beam solid angle of some 5 to 30 ° already light intensities in the range of 25,000 mCd and in pulsed operation also beyond. In such light levels provides the dissipation of heat loss and the Type of contacting already a major problem. For the use of the usual long life of some 10,000 to 100,000 hours must solve this problem be. In the present case provide for the dissipation of heat the frame profiles, which are preferably made of aluminum. In such Cases, the wiring substrates must be thermal be fixed well conductive on the frame profile. It can also already the wiring substrates of corresponding aluminum printed circuit board material be made.

For Moreover, a number of applications are not just the usual ones red and green and yellow and blue signal colors of Interest, but white light is preferred. such LED's are usually operated in the blue range. By color-converting lens body becomes a white one Emission generated. There are inorganic admixtures in the Polymer matrix of the lens body used and become Extremely long-term stable emission spectra without color shifts achieved.

additionally there is still the possibility of using so-called R-G-B LEDs, that is LED's with 4 electrical connection elements and the emission colors red-green-blue. In such LED elements Although the electronic circuitry is more complex, it However, all mixed colors can be electronically be generated and readjusted. It can also vary depending on Training the electronic control different color effects generated in chronological order and optionally by means of sensors to be controlled.

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

exemplary becomes an LED strip of the company Osram Opto Semiconductors with the Type designation LINEARlight flex OS-LM11A used. Such a LED strip comes with 8.4 m total length and a basic size of 10 LEDs with a length of 140 mm and a height smaller 3 mm and a strip width of 10 mm. The backside This LED strip is self-adhesive.

The power supply is 24 volts DC, nominally the smallest unit to be operated of 10 LED's with 140 mm length each needed according to emission color between 40 and 50 mA. Nominally, a luminous intensity of 95 mcd (blue) to 305 mcd (white) and 730 mcd (yellow) is effected. The power consumption of the 10 LED's is 0.96 to 1.2 watts or 6.9 to 8.6 watts per meter. The beam angle of these LED components is 120 °.

Of the Operating for example 1 to 10 LED running meters can therefore be very good by inexpensive and simple power supplies take care while paying attention to no double insulation rule.

Of the Beam angle can be adapted to the respective application and it can with special Linsenanformungen and / or In addition, asymmetrical emission characteristics can be achieved. Furthermore, it may be advantageous to install a diffuser. This can in the present case in the interior of the insulating glass element very easy due to transparent elements with good photoconductive and Scattering surface can be achieved.

When Substrate for such LED strips can be unilateral and double-sided flexible printed circuit boards based on, for example Polyamides (PI) and / or polyethylene terephthalate (PET) or Polyethylene glycol terephthalate (short name PETP or PET) and / or polyethersulfone (PES) and / or polyetherimide (PEI) and / or Polyetheretherketone (PEEK) and / or aramid and / or fibrous flexible films and the like can be used. It will be thin Copper foils and / or aluminum foils applied and accordingly structured according to the wiring requirements.

This can by the usual in the printed circuit board industry process and it can be both photographic as well as also screen printing masking method followed by etching be used. In addition, the structuring is also provided by laser beams.

As a third embodiment, light elements are described from photoluminescent substances in the form of strips:
Low cost, zinc sulfidic, photoluminescent pigments are used. These are embedded in a polymeric matrix and applied with conventional coating technologies. The use in the form of a self-adhesive strip has the disadvantage of a relatively low afterglow duration and low resistance to UV radiation and water vapor.

in the The present case is in the arrangement in the interior of an insulating glass element neither a water vapor load, nor a high UV exposure given. By conventional glass panes in the form of float glass or cast glass At least the UV-B radiation is greatly reduced and optionally is also an additional coating UV-A Reduced radiation.

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

usual, Strontium aluminate-based pigments are very fine-grained in sizes of a few microns, typically 10 Microns to coarse-grained pigments of typically 50 Micrometer dimensions available. They have long persistence times from over 20 hours to 50 hours on and off emit in a typical wavelength range of about 400 nm to 640 nm, where typically the yellow-green area best perceived by the human eye at about 520 nm can.

there Not only excitation in the UV range can be availed. It can already usual artificial Illuminations, for example based on fluorescent tubes, or other lamps cause a charge. Usually will the excitation in the range 200 to 450 nm with a good efficiency and reach a typical maximum at 380 nm.

Usually, the afterglow period for escape route markings is measured according to DIN 67510 and other standards. The dark adapted eye still perceives luminance values of about 0.01 mcd / m ² true. In the DIN 67510 0.3 mcd / m ^{2 is recorded} as the value that is metrologically used for the Nachleuchtvermögen a system for comparison purposes and it must be over 5.7 hours. Furthermore, long afterglow systems according to DIN 67510 must have a luminance of greater than 2.8 mcd / m ² after 60 minutes in a dark environment.

Next the commercially available strontium aluminates are silicates based on rare earth doped long persistence pigments due to their high temperature resistance up to the range 600 to 800 ° C interesting, however, have such Pigments then shorter persistence times.

All in the documents, including the abstract Information and features, in particular the spatial shown in the drawings Training, are claimed as essential to the invention, as far as individually or in combination with the state of the art Technology is new.

The Invention will now be described with reference to several embodiments described in more detail. Here are the drawings and their description further advantages and features.

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 carried out with sun protection effect and can be such a light element ( 11 . 23 . 24 . 29 ) are arranged so that special night lighting effects are possible.

In 1 an arrangement is shown in sectional view, with left and right 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 are fixed by means of a spacer ( 4 ) in the form of a profile frame and further a seal ( 5 ) composed of, for example, polyvinylbutiral (PVB), silicone, polyurethane (PU), polyethersulfones (PES), polysulfones (PSU), and the like.

This forms a hermetically sealed interior ( 18 ), which is usually filled by a noble gas. The gas pressure is set according to the barometric air pressure at the place and at the time of production. Thus, 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 ) is dried with drying agent ( 10 ) and the frame profile ( 4 ) becomes the interior ( 18 ) with breakthroughs ( 17 ) Mistake. This will make the interior ( 18 ) kept free of water vapor, which for the life of conventional EL strips ( 11 . 23 ) in use in such long-life 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 ) are sealed. In order to achieve a correspondingly durable seal, lines ( 23 ), which do not exchange gas with the interior ( 18 ), such as lacquered copper wires and the like.

For the operation of EL strips ( 23 ) so-called EL inverter or converter are needed. Typically, a DC low voltage is converted to an AC of a few hundred to 200 volts and above and frequencies of 50 Hz to 2,000 Hz and above to outside the listening area. Such electronic components can, depending on the design in the interior ( 18 ) or in the interior of the frame profile ( 4 ) or outside.

The light emission ( 15 ) takes place from the surface of the EL strips ( 11 . 23 ). By an appropriate coating ( 6 . 7 . 8th . 9 ) of glasses ( 1 . 2 ), both light refraction effects of the emission radiation ( 15 ), as well as mirrored effects are effected. Depending on the choice of the mirror layer ( 6 . 7 . 8th . 9 ) an EL strip can also be invisible 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 Fixing means ( 13 ) respectively. For this purpose, self-adhesive systems or cold adhesive systems or hot melt adhesive systems and the like fastening means can be used. The EL strip can also be arranged around the circumference or in pieces.

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

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

When using LED strips ( 24 ) usually several LED components ( 25 ) in series, whereby the power supply can be brought to typically 12 or 24 or 48 volts and thereby the required operating current can be reduced. The energy supply is very easy by means of electrical connection cables ( 12 ) through the frame profile ( 4 ) are guided and by means of the seal ( 5 ) are sealed. The connecting cables ( 12 ) must also be protected against gas diffusion, which is well met for example by enamel-insulated copper wires.

The at least one LED strip can be as in 1 described by a variety of attachment methods via a fastener ( 13 ) on the inside of the profile frame ( 4 ) are attached. For high power LED strips ( 24 ), the heat dissipation of the frame profiles ( 4 ) be used. In particular, an aluminum is suitable as a frame material. The contacting of the LED strips can in such cases with good heat-conducting fastening means ( 13 ) respectively. All other details apply analogously to 1 ,

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

In 5 is a schematic representation of an arrangement shown in a sectional view, in which case only the frame ( 4 ) inside with an EL strip ( 11 . 23 ) is executed. The attachment of the EL strips ( 23 ) by means of fastening means ( 13 ) can be like in 1 described using a variety of methods.

A commercial EL strip ( 23 ) can be made in very long lengths of typically 90 or 100 meters and above. In this case, aluminum foils are usually separated by various processes, and as a result EL electrode electrodes ( 19 ), which, owing to their good conductivity, hardly cause a voltage drop over very long distances and therefore prevent the operation of such EL strips ( 23 ) over very long lengths.

On the EL splitter electrodes ( 19 ) an insulating layer or a dielectric layer is added and then a largely transparent polymer matrix with zinc sulfide electroluminophores ( 20 ) of typically some 15 to 50 micrometer sized pigments and above a transparent cover electrode ( 21 ). Usually, metal-oxide and / or metal-nitridic microencapsulated electroluminophores ( 20 ) and thus the so-called half-life can be increased to some 2,000 hours.

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

In the present invention, however, these lifetime-limiting properties play no role, since in the interior ( 18 ) anyway, the water vapor content is extremely low.

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

In 7 is in analogy to 5 a schematic representation of an arrangement in a sectional view with an LED strip ( 24 ge shows. Unlike the mounting of an EL strip ( 23 ) when using high power LED strips ( 24 ) on a good heat transfer to the frame profile ( 4 ) and accordingly, the fastener ( 13 ).

In 8th becomes a typical LED strip ( 24 ) shown in plan view. Such an LED strip is available 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 LED's ( 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 by means of scissors. The LED pitch ( 27 ) is 14 mm in this design. The back of these LED strips is self-adhesive. The power supply is provided by 24 V DC ( 12 ). Nominally, the smallest unit to operate of 10 LED's with 140 mm length, depending on the emission color, needs between 40 and 50 mA to nominally illuminate from 95 mcd (blue) to 305 mcd (white) and 730 mcd (yellow). The power consumption of such units of 10 LED's is 0.96 to 1.2 watts and 6.9 to 8.6 watts per meter. The beam angle of these LED components is 120 °.

In 9 a schematic representation of an arrangement is shown in sectional view, wherein only the frame ( 4 ) with a long-lasting luminescent layer ( 29 ) is pictured. Since when using aluminum as the material for the frame profile ( 4 ) reflects the surface very well, in this cost-effective arrangement, the inside of the frame profile ( 4 ) with a photoluminescent layer ( 29 ) of a well-adherent and transparent polymer matrix ( 31 ) with embedded long-luminescent pigments ( 30 ) are coated. The coating can be done by brushing, knife coating, dipping, spraying, screen printing and the like coating methods. For most of these methods, the frame breaks ( 17 ) free. However, it may also be a subsequent production of these frame breakthroughs ( 17 ) respectively. When using inexpensive, zinc sulfidic, photoluminescent phosphors ( 30 ) is to pay attention to the absence of water vapor, as this persists the persistence over a much longer period.
