The shelves 341 in the present case comprise a frame 343 , in which a glazing with a transparent to visible light bulbs 100 is introduced. For electrical contacting include the brackets 342 the shelves present a pen 71 which is in an electrically conductive recess 73 inside the bars 83 is used as in 13B shown.

14 shows a schematic sectional view of a reflective display 335 , A reflective display 335 includes on its back a reflective element 337 , on the pixel 338 are arranged. Reflective displays 335 do not require backlighting, but reflect due to the reflective element 337 Ambient light such that the display content can be displayed. Therefore, reflective displays 335 dependent on the ambient light. In the dark, these are no longer readable. On the radiation-emitting front 335a of the reflective display 335 is a transparent to visible light bulbs applied, such as based on the 5A described. In the present case, this luminous means is designed such that it predominantly emits radiation in the direction of the reflective element. For better color rendering, the bulb 100 slightly colored, for example in the color of a light magenta. For this example, the encapsulation 6 or the substrate 1 or both colored in the desired color. The bulbs are preferred with an index matching material on the front 335a of the reflective display to avoid reflections. If the luminous means can be varied in color, for example in such a way that the color space RGB is covered, and the reflective display can 335 continue to switch fast enough, a time-sequential operation in RGB is possible. In this time-sequential operation, the display is preferably operated at frequencies of at least 70 Hz, more preferably at least 100 Hz.

The 15 shows a schematic sectional view of a light bulb 100 according to an embodiment. The electrodes 2 . 3 , the substrate 1 , the encapsulation 6 and the organic layer stack 4 are transparent to visible light, in particular that of the organic layer stack 4 generated light, formed. On the outside of the substrate 1 , which may be formed by a glass plate, for example, is a reflective element 337 , which in the present case is a reflective layer sequence. The reflective layer sequence comprises a copper layer 337b , a silver layer 337a and a protective varnish layer 337c where the silver layer 337a on the substrate 1 is applied, the copper layer 337b on the side facing away from the substrate of the silver layer 337a and the protective lacquer layer on the copper layer 337b , As the reflective layer sequence along the bottom 100b of the bulb 100 is formed, the bulb can 100 emit no more light from it, but only from its top 100a , Furthermore, the reflective element reflects light that passes through the first electrode 2 and the substrate 1 passes through in the direction of the top 100a of the bulb 100 ,

As an alternative to the layer sequence described above with a silver layer, a copper layer and a protective lacquer layer, it is possible to use as a reflective element 337 For example, a dielectric mirror may also be used which, like the layer sequence, is applied on top of the outside of the substrate.

The reflective element 337 For example, such as a reflective layer sequence or a dielectric mirror may continue to be on the outside of the encapsulant 6 applied or between substrate 1 and first electrode 2 as well as between encapsulation 6 and second electrode 3 to be appropriate. Is the reflective element on the outside of the encapsulation 6 or between encapsulation 6 and second electrode 3 arranged, so sends the bulb 100 Light from its bottom 100b out.

A light source 100 as it is in the 15 is shown, it allows in particular to serve as a mirror when the lighting means is deactivated and during operation of the lighting means 100 as a source of illumination. With such a light source 100 can be either the entire light-emitting front 100a to serve as lighting or as a mirror. Furthermore, it is also possible that the entire light-emitting front 100a serves as lighting and as a mirror. Furthermore, the light-emitting front side 100a also be divided into areas, so that part of the light-emitting front 100a serves as a mirror and another part as a source of illumination.

By way of example, however, the luminous means can also be designed such that it emits light both from its front side 100a as well as from his back 100b radiates. For example, using the so-called cavity effect, it is possible that It emerges from different sides of the bulb light with different light properties. Such a light source is for example in the German patent application 102006046196.7 whose disclosure content is hereby expressly incorporated by reference.

16 shows a schematic sectional view of a light bulb 100 according to a further embodiment. Following elements of the bulb 100 are permeable to visible light: encapsulation 6 , Substrate 1 , first electrode 2 and organic layer stack 4 , As a substrate 1 For example, a glass plate or a plastic film permeable to visible light may be used.

The first electrode 2 can be formed for example from a TCO.

In the organic layer stack 4 it can be a layer stack, as it is based on the 1 already described.

In the encapsulation 6 it may be, for example, a glass cap, a glass plate, a plastic cap or a plastic plate.

Furthermore, on to the organic layer stack 4 facing inside of the cap or plate, a getter material may be applied, which is also transparent to visible light. Furthermore, it can be in the encapsulation 6 to be a thin-film encapsulation having at least one barrier layer. The barrier layer can for example consist of SiO _x or SIN _x or have one of these materials. Furthermore, the thin-film encapsulation 6 also first and second barrier layers 601 . 602 have, which alternate with respect to their material composition. For example, polymer interlayers may be arranged between the alternating barrier layers; see, for example, the US Pat 3 ,

17A shows a schematic sectional view of a Dünnfilmverkapselung 6 with alternating barrier layers 601 . 602 , wherein in each case between two adjacent barrier layers of different material composition, a polymer intermediate layer 604 is appropriate. For example, the barrier interlayers may be two barrier layers 601 which have SiO _x and two barrier layers 602 that have SIN _x as associated with 3 already described. As in the embodiment according to the 3 are the barrier stories 601 . 602 arranged alternately with regard to their material composition, that is to say that first barrier layers 601 with second barrier layers 602 within the thin-film encapsulation 6 alternate, with the first and second barrier layers 601 . 602 have different material composition. In contrast to the thin-film encapsulation 6 according to the 3 are the barrier stories 601 . 602 however, by polymer interlayers 604 separated from each other.

Alternatively to the use of a separate reflective element 337 , such as the above-described reflective layer sequence or the dielectric mirror, is the second electrode 3 of the light source according to the 16 reflective designed for visible light. For this purpose, the second electrode comprises 3 For example, aluminum or silver or consists of one of these materials. Such a light source is also suitable to serve as a mirror and / or illumination source, as the lighting means according to the 15 ,

In order to obtain a luminous means which can serve as a mirror and / or as a source of illumination and has no additional reflective element, it is also possible to use the second electrode 3 permeable to visible light, for example by using a TCO as the electrode material, and instead the encapsulation 6 , the substrate 1 or the first electrode 2 to train reflectively.

For a reflective encapsulation 6 For example, it may be a polished metal cap.

17B shows a schematic sectional view through a reflective encapsulation 6 according to an embodiment. This is a cap that is either already reflective, for example, by being formed of a polished metal, or a cap that is not reflective. On top of the organic layer stack 4 facing inside of the cap is a reflective element 337 , for example, applied a reflective layer. The reflective layer on the inside of the cap can be, for example, a metallic layer which has approximately silver or consists of silver. Furthermore, the reflective layer can also have multiple layers. On the reflective layer is still a getter layer 611 applied from a getter material that is transmissive to visible light.

17C shows a schematic sectional view through a thin-film encapsulation 6 according to a further embodiment. The thin-film encapsulation 6 shows how the thin-film encapsulation 6 according to 17A alternating barrier shit th 601 . 602 on, by polymer interlayers 604 are separated from each other. In contrast to the thin-film encapsulation 6 according to 17A indicates the thin-film encapsulation 6 according to 17C a reflective element 337 , For example, a reflective layer sequence, as based on the 15 already described. The reflective layer sequence comprises a silver layer 337a on the outermost barrier layer 602 is applied. On the silver layer 337a is a copper layer 337b applied, on the turn a protective lacquer layer 337c is arranged. Due to the reflective layer sequence, the thin-film encapsulation is reflective and can be used as a reflective encapsulation.

Another option, a bulb 100 Forming, in which switching between mirror function and lighting function can be switched back and forth, consists of the substrate 1 form reflective, while the other elements of the lamp, that in the organic layer stack 4 generated light on the way to the light-emitting front 100a has to go through, in particular the second electrode 3 , the organic layer stack 4 and the encapsulation 6 permeable to visible light. A reflective substrate 1 may for example comprise metal or consist of a metal. As a reflective substrate 1 For example, a metal foil such as a stainless steel foil may be used. In particular, a mirror may be used as the substrate. Next is a laminate of plastic films, on which a metal foil - for example, aluminum - is laminated, as a reflective substrate. Furthermore, the substrate may be a reflective coated glass substrate.

Alternatively or in addition to a reflective substrate 1 can also be the first electrode 2 be formed reflective. Such may, for example, comprise or consist of one of the following materials: aluminum, silver.

Further, it is also possible that the Dünnfilmverkapselung 6 itself forms a dielectric mirror or a Bragg mirror. The material of the first and second barrier layers 601 . 602 and the thickness of these layers is then selected accordingly.

That means the light source 100 is flexible enough to roll up into a roll and from a roll 32 in the direction of the arrow 32 let it roll. This allows in addition to a particularly space-saving storage of the bulb 100 a particularly simple use of the bulb 100 For example, for pasting furniture, Treppenabsätzen, walls, tiles, tiles or sanitary facilities.

The 34A shows an embodiment of a lighting device described here 1000 in a schematic plan view.

The 34B shows the lighting device 1000 in a schematic sectional view along the section line AA '.

At the lighting device 1000 according to the 34A and 34B it is a flexible lighting device. The flexibility of the lighting device 1000 is thereby achieved that rigid bulbs 100 , that means bulbs 100 which in themselves have no flexibility, since they are for example a rigid substrate 1 and / or a rigid encapsulation 6 in a flexible matrix 40 are embedded.

The lighting device 1000 includes two flexible carriers 42 . 43 between which are the rigid bulbs 100 and the material of the matrix 40 are arranged. At least the carrier 43 through which the bulbs 100 which emit light generated in operation is translucent. The other carrier 42 may be formed of an opaque, for example, reflective trained material such as a metal foil.

The space between the two carriers 42 . 43 is with the rigid bulbs 100 and a flexible matrix material 40 filled. The translucent matrix material may contain particles of at least one of the following materials: luminescent conversion material, color filter material, diffuser material.

The rigid bulbs 100 can do it be arranged so close to each other, that - optionally by the diffuser particles contained in the matrix material - a homogeneous light impression of the lighting device 1000 results. That means individual bulbs 100 are then no longer perceptible by the viewer, but the lighting device 1000 has a single, homogeneous luminous surface.

Alternatively, it is possible that the bulbs 100 are arranged so far apart from each other that webs between the bulbs are perceptible. In this case, the space between individual light sources can be filled with a matrix material which has light-absorbing particles. The light-absorbing particles may be, for example, carbon black or particles of dyes.

The tracks 41 which the individual bulbs 100 the lighting device 1000 connect together, are arranged in the matrix material. This ensures the flexibility of the lighting device. The tracks 41 are formed by thin, metallic springs or meandered, thin wires.

The carriers 42 . 43 the lighting device 1000 can be chosen so viable that the lighting device 1000 Loads of weights up to several hundred kilograms unscathed survives. In this way is a use of the lighting device 1000 as flooring possible.

The 35B shows a schematic sectional view of the lamp 100 of the 35A along the section line AA '.

In the light bulb, in conjunction with the 35A and 35B is described, it is a multi-colored light source.

As in the plan view of 35A schematically illustrated, the lighting means comprises first and second color subregions, which are arranged laterally side by side. The first 50 and second 51 Color sub-areas are suitable for emitting light of different colors. The first color sub-area 50 is suitable to emit light of a first color. The second color sub-area 51 is capable of emitting light of a second color. The first color differs from the second color.

Im in conjunction with the 35A described embodiment of the lighting means are the first and second color sub-areas 50 . 51 arranged in a checkerboard pattern to each other. That is, the first and second color sub-areas 50 . 51 are arranged at the grid points of a square grid such that each first color sub-area 50 that is not on the edge of the bulb 100 is arranged, four second color sub-areas 51 as the next neighbor, lateral to the first color sub-area 50 adjoin. The same applies to the second color subregions 51 ,

The color sub-areas 50 . 51 are formed in the manner of pixels of a display. The size of each color sub-area is preferably at least 1 mm ² .

As in the schematic sectional view of 35B is clarified, the first and second color sub-areas 50 . 51 different Lumineszenzkonversionsmaterialien or different color filter materials include, which are responsible for the different color impression of the first and second color sub-areas. So include the first color sub-areas 50 For example, a first luminescence conversion material and / or a first color filter material 52 , The second color sub-areas 51 then comprise a second luminescence conversion material and / or a second color filter material 53 ,

In this case, the luminescence conversion materials or the color filter materials can be arranged in a layer of the luminous means which is parallel to the first main surface 101 of the substrate 1 of the bulb 100 runs and which is arranged such that at least a majority of the organic layer stack 4 generated in operation electromagnetic radiation through this layer occurs.

Im in conjunction with the 35B described embodiment, the lighting means 100 a substrate 1 to which a first electrode is applied. On the side facing away from the substrate of the first electrode 2 is the organic layer stack 4 applied, which comprises at least one provided for generating light organic layer.

The organic layer stack 4 follows on its the first electrode 2 opposite side, a second electrode 4 to.

On the organic layer pile 4 opposite side of the second electrode 3 the layer is arranged, which is the first 52 and second 53 Lumineszenzkonversionsmaterialien and / or the first and second color filter materials. The light source 100 is through an encapsulation 6 hermetically sealed off from the environment.

By appropriate structuring of the first 2 and / or second electrode 3 It is possible that the color subregions are independently controllable.

The structure of the bulb 100 can be done in particular as in any of the other described embodiments. As a result, it is particularly easy to realize flexible, translucent and / or reflective luminous means which have at least two color subregions.

When first and / or second luminescence conversion materials are suitable for example, the materials described above.

When First and second color filter materials are suitable, for example the materials described above.

For reasons of a simplified representation are in connection with the 35A and 35B described embodiment, only two different color sub-areas shown. However, it is possible that the bulbs 100 has a greater number of different color subregions capable of producing in pairs light of different colors.

In the extreme case, the color of the light of each color sub-area differs from the color of the light of another color sub-area of the illuminant. This is schematically in the 35C shown, which is another embodiment of a multicolor illuminant described herein 100 explained with reference to a schematic plan view. In this embodiment, the illuminant has five different color subregions 50a to 50e each generating light in pairs of different colors.

For example, the encapsulation 6 of the bulb 100 be formed by a plate or flexible film, in which the materials are embedded.

This allows a light source 100 in which by the choice of encapsulation 6 the desired color impression of the bulb 100 can be adjusted. The structure of the bulb 100 With regard to the remaining elements of the luminous means, it can be carried out as in one of the embodiments discussed above or below. As a result, it is particularly easy to realize flexible, translucent and / or reflective luminous means which have at least two color subregions. The functional components of the bulb, such as the first 2 and second electrode 3 as well as the organic layer stack 4 , regardless of the encapsulation 6 be made.

In this embodiment, the different color sub-areas 50 . 51 of the bulb 100 realized by different emitter materials in the organic layer stack. That is, the organic layer stack is structured in the lateral direction. First and second color subregions differ at least in terms of an organic layer provided for light generation. The first color sub-area 50 has, for example, a first emitter material, the second color subregion 51 then has a second emitter material different from the first emitter material. The structure of the bulb 100 can then take place with respect to the other elements of the luminous means as in one of the other embodiments. It is especially one fold flexible, translucent and / or reflective bulbs feasible having at least two color sub-areas.

The 38 shows a schematic plan view of the first and second electrodes 2 . 3 for a further embodiment of a multi-colored lighting means 100 , Again 38 it can be seen, are the first and second electrodes 2 . 3 each formed strip-shaped.

In this embodiment, all first color sub-areas 50 and all second color sub-areas 51 each by electrical connections 54 respectively 55 connected with each other. This means, for example, all first color sub-areas 50 are jointly and simultaneously controllable in this way. Likewise, all second color sub-areas 51 jointly and simultaneously controllable. The first and second color sub-areas 50 . 51 on the other hand, are separately controllable. Such a trained light source 100 thus has four operating states:

• • the light source can be switched off, so that none of the color subregions generates light, ie none of the color subregions lights up;
• • all first color sub-areas 50 of the bulb 100 light up, the second color sub-areas 51 do not shine
• • all second color sub-areas 51 of the bulb 100 light, the first color sub-areas 50 do not shine, and
• • the first and second color sub-areas 50 . 51 shine so that the bulb 100 Light of the first and the second color emitted.

Like the cropping of the 40B can be seen, includes each bulb of the lighting device 1000 four color subregions 50a . 50b . 50c and 50d :

• • The first color sub-area 50a is suitable, for example, during operation of the lighting device 1000 To emit light of green color.
• • The second color sub-area 50b is suitable in the operation of the lighting device 1000 Emit light of red color.

Optional is the bulbs 100 the lighting device 1000 at its light emitting front 100a an optical element 60 downstream. In the optical element 60 it is preferably a diffuser plate. That is light, which is the optical element 60 radiates from the optical element 60 scattered. In this way, the individual color subregions are in operation of the illumination device 1000 The viewer no longer perceived as separate elements, but the lighting device 1000 appears as if it has a single, homogeneous light area. The illuminated area of the illumination device 1000 is composed of the light-emitting front sides of the lighting means of the illumination device.

The optical element 60 It is also preferable for the mixture of the color subregions 50a . 50b . 50c . 50d the single bulb 100 generated light suitable. In this way, the lighting device 1000 suitable, in addition to light of the colors of the individual subregions, to produce mixed light of two or more of these colors. Overall, a particularly flexible illumination device is realized in this way, which is suitable in a simple way to produce light of a variety of different colors.

Assign the bulbs 100 the lighting device 1000 additionally at least one color sub-area 50d On, which is suitable to produce white light, so can the illumination of this color sub-range and the brightness of the illumination device 1000 radiated light are particularly easy to adjust.

The 41 shows a schematic plan view of another embodiment of a light bulb described here 100 , The light source 100 has at least two color subregions 51 and 50 on.

That is when the bulb 100 are energized in a first direction, for example, the first color sub-areas 50 switched in the forward direction, so that they produce light of the first color. The second color sub-areas 51 are then switched in the reverse direction, so that no light is generated in the second color subregions.

By simply reversing the current direction, in a next time step, the second color sub-areas can 51 be energized in the forward direction, so that light of the second color is generated. The first color sub-areas 50 are then switched in the reverse direction, so that in the first color sub-areas 50 no light generation takes place.

The color sub-areas 50 can be integrated on a common substrate. In addition, it is also possible that the color subregions are individual, small light sources that are connected in anti-parallel to one another.

The control of such a light source 100 is preferably carried out by means of a control device 11 into which a pulse width modulation circuit 12 is integrated. The pulse width modulation circuit 12 is suitable for generating current having a first current direction for first time periods.

In this embodiment, a control device 11 together with the organic layer stack of the luminous means 100 on the first main area 101 of the substrate 1 arranged. The control device 11 can contain, for example, an organic material. Advantageously, the control device can then with the same production methods as the active area 5 be made.

This allows a particularly cost-effective production of the light source 100 , The control device 11 is - either via additional electrical leads 9 , such as bonding wires 902 or by means of the first and second electrodes 2 . 3 with the organic layer stack of the illuminant 100 electrically connected. The control device 11 is suitable for the active area 5 of the bulb 100 to be supplied in a predeterminable way.

In particular, it is also possible that the control device 11 from outside - for example, by a user of the bulb 100 - is adjustable. That is, a user can have a certain operating state of the lighting means 100 over the control device 11 to adjust. As the 43 further shows, are the control device 11 and the organic layer stack of the luminous means 100 from a common encapsulation 6 encapsulated. In the encapsulation 6 it is one of the in connection with the above-described bulbs 100 listed encapsulations 6 , That is the encapsulation 6 is formed for example by a glass, a plastic film, a plastic-glass-plastic laminate, a metal foil, a metal sheet, a cap or a Dünnfilmverkapselung. The encapsulation 6 and / or the substrate 1 of the bulb 100 are translucent.

The 44 shows a further embodiment of a luminous means described here 100 in a schematic plan view. In this embodiment of the luminous means are both a photodetector 65 as he in connection with the 42 as well as a control device 11 as related to the 43 is described in more detail, together on the first main surface 101 of the substrate 1 of the bulb 100 arranged. This enables a particularly compact and autonomous light source 100 , The photodetector is preferably with the control device 11 connected, which is suitable, depending on by the photodetector 65 determined measured values of the organic layer stack of the light source 100 to energize. The measured values can be, for example, the brightness and / or the color locus of the organic layer stack 4 of the bulb 100 acted light act. Furthermore, it is possible that the photodetector 65 is additionally or alternatively provided for the detection of the ambient light. A current flow of the organic layer stack is in this case also dependent on the ambient brightness.

Im in conjunction with the 44 described embodiment of the bulb 100 In particular, it is possible that the organic layer stack, the photodetector 65 and the control device 11 at least each contain an organic material. These elements of the bulb 100 can be made by the same manufacturing methods. This allows a particularly simple and cost-effective production of the light source 100 ,

In conjunction with the schematic sectional view of 45 is another embodiment of a light bulb described here 100 explained.

Each of these light generating layers forms a color subregion of the light source 100 , That is, the color subregions of the illuminant are vertically stacked in this embodiment. The different layers provided for the generation of light preferably differ with regard to their emitter material. The layers are therefore suitable for producing light of different color during operation of the luminous means. For example, the first layer provided for generating light is 403 suitable to produce red light. The second layer 404 is then suitable to produce green light. The fourth layer intended to generate light 405 is suitable to produce blue light.

• - red: TER-012
• - red: DCM2: 4- (dicyanomethylene) -2-methyl-6- (julolidine-4-yl-vinyl) -4H-pyran

The remaining elements of the bulb 100 such as the substrate 1 , the first electrode 2 , the second electrode 3 and the encapsulation 6 are according to one of the other embodiments of bulbs 100 executed.

The 46 shows that in conjunction with the 45 illustrated bulbs 100 in a cup matic perspective sketch. The light source is equipped with a control device 11 connected, which is suitable to the color of the bulb 100 to set the generated light. The control device 100 For this purpose, preferably comprises a pulse width modulation circuit 12 , Depending on the electric field strength, which occurs when the light source is energized 100 between the first electrode 2 and the second electrode 3 in the layer stack 4 adjusts the recombination of the charge carriers in the organic layer stack 4 be controlled so that the recombination predominantly take place in a specific, specifiable, provided for generating light layer. That is, in this way, it can be set, for example, that the recombination is mainly in the light generation layer 404 takes place. In this way, then mostly green light from the bulb 100 generated.

The field strength in the organic layer stack 4 is thereby by the pulse width modulation circuit 12 the control device 11 adjustable. The electric field strength can be regulated, for example, by the pulse duration and the pulse height of the pulse-width-modulated signal.

As the 47 illustrated schematically, the color in the CIE standard color chart is that of the bulb 100 depending on whether the pulse width modulation circuit 12 a pulse width modulated signal with a short pulse duration 1220 generated or the light source 100 by means of a continuous stream 1210 is energized.

The pulse height of the pulse width modulated signal essentially determines the brightness of the light source 100 generated light. In summary, that means color and brightness of the bulb 100 generated light can by means of the pulse width modulation circuit 12 be set.

The control device 11 Can additionally with a photodetector 65 be connected. The photodetector 65 is, for example, as in connection with the 42 and 43 described, suitable, the color location and / or the brightness of the light source 100 detected light to detect. The setting of a specific color location of the light source 100 generated light is then regulated by a function of the photodetector 65 determined values possible.
