Description

[0001] The invention relates to an arrangement of a lighting device on a laminated / composite / laminated glass of a vehicle according to the preamble of claim 1. The invention also relates to a vehicle, in particular a motor vehicle, according to claim 7 and a laminated glass / glass pane according to the preamble of claim 9. Background Art

[0002] EP 0 997 333 B1 discloses a transparent roof module for a vehicle roof having a transparent pane designed as a transparent glass pane, wherein at least a portion of the surface of the pane which, for structural reasons, is not available for viewing from the vehicle interior to the outside and only this portion is provided with solar cells. Summary of the invention

[0003] The object of the present invention is to provide an arrangement of a lighting device on a laminated glass of a vehicle, a vehicle having such an arrangement, and a laminated glass for a vehicle, which enable particularly high robustness, in particular robustness against glass breakage, to be achieved.

[0004] This object is achieved according to the invention by an arrangement having the features of claim 1, a vehicle having the features of claim 7 and a laminated glass having the features of claim 9. Advantageous embodiments of the invention are the subject matter of the dependent claims.

[0005] The invention relates to an arrangement of a lighting device on a laminated glass of a vehicle, in particular a motor vehicle. The laminated glass has two plates / glass sheets arranged at least partially overlapping each other. Thus, at least corresponding partial areas of the plates overlap each other. In particular, the plates, which are preferably configured as glass sheets, overlap each other at least for the most part, in particular completely. The laminated glass also has a film arranged between the plates, in particular between the overlapping partial areas of the plates. In particular, the film is formed by plastic and is therefore configured as a plastic film. For example, the plastic forming the film can be PVB (polyvinyl butyral), so that the film is preferably formed as a PVB film. The plates and the film and the laminated glass are light-transmitting and, for example, are used as roof elements of a vehicle roof or for a roof element, so that the interior space of the vehicle is at least partially delimited by the laminated glass in the vehicle height direction upwards. In this case, it is conceivable that the roof element is constructed separately from the vehicle body that delimits the interior space and is connected to the body. Since the film and the plate are light-transmitting, for example, light from the vehicle environment, in particular sunlight, can penetrate the laminated glass and, in particular if the interior space is not shaded, can enter the interior space. The roof or the roof element is therefore in particular a glass roof.

[0006] In this arrangement, the lighting device has at least one light source, which is, for example, electrically operable. The light source can provide light, i.e. emit light, in particular by electrically operating the light source. The light source is at least partially, in particular at least mostly or completely, arranged in a corresponding recess of one of the plates. If the light source provides light, the light provided by the light source can be fed into, i.e. coupled into, the plate and fed into the laminated glass via the plate, so that, for example, a particularly advantageous illumination of the laminated glass and the interior can be achieved. For example, the light source is designed as a light emitting diode (LED).

[0007] In order to achieve a particularly high robustness of the laminated glass, in particular with respect to resistance to breakage, that is, in order to keep the breakage sensitivity of the laminated glass particularly low, it is proposed according to the invention that the sheet with the recess is provided, in particular only provided, on its side facing away from the other sheet and the film and facing the interior of the vehicle (also referred to as the inner side), with at least one coating, in particular only with at least one coating, for example directly contacting the inner side, which covers, in particular completely covers, the recess and the light source, respectively. It has been found that recesses, also referred to as holes or openings, for example formed in and / or drilled into a sheet weaken the sheet and reduce its mechanical stability. In addition, the recesses lead to increased internal stresses in the sheet. It is conceivable that the lighting device has at least one additional light source or several additional light sources, in which case the previous and following statements about the first light source can also be directly transferred to each additional light source, and vice versa. It is therefore conceivable that each additional light source is at least partially arranged in a corresponding additional recess of the sheet, wherein the following and previous statements about the first recess can also be directly dedicated to each additional recess, and vice versa. The greater the number of light sources and corresponding recesses of the one-piece plate, the more the plate, in particular configured as a glass sheet, is weakened. In other words, the shatter sensitivity of the one-piece plate increases with the number of recesses. In the present invention, the one-piece plate is now reinforced by a coating, whereby an advantageously high robustness of the one-piece plate, in particular with regard to resistance to shattering, can be achieved. If the one-piece plate has a plurality of recesses, in which a corresponding light source is arranged in each case, it is conceivable that the one-piece plate is partially provided with a corresponding coating on its side facing away from the other plate and the film, which coating in particular completely covers the corresponding recess and the corresponding light source in each case, wherein it is conceivable that the coatings are spaced apart from one another and are therefore separated from one another.

[0008] However, it has been found to be particularly advantageous if the coatings are connected to one another, in particular on the surface, with the result that the coatings form a particularly continuous overall coating. In other words, it has proven to be advantageous if the one sheet is provided with a coating on its side facing away from the other sheet and the film, which coating in particular completely covers both the recess and the light source, respectively, and is thus a monolithic coating such as described above. Thus, the one sheet can be particularly advantageously reinforced.

[0009] For example, the side of the one plate faces the interior space, so the inner side of the one plate facing the interior space is arranged on the inner side of the other plate facing the interior space, so it is configured as an inner plate, and is configured as an inner plate. Therefore, for example, the other plate is arranged on the outer side of the one plate facing away from the interior space, so that the other plate is, for example, an outer plate, that is, an outer plate.

[0010] In order to be able to particularly advantageously reinforce the one-piece plate by means of the coating, so that a particularly high degree of robustness can be achieved, provision is made in one embodiment for the coating to be formed from plastic.

[0011] It has proven to be advantageous if the plastic forming the coating is ethylene vinyl acetate (EVA). Thus, a particularly high degree of robustness can be achieved.

[0012] It is conceivable that the coating is a plastic film, in particular a plastic film provided in addition to the film, and very preferably formed from EVA, and thus configured as a tear-resistant EVA film. In particular, the plastic film can be a shatterproof film, which can very preferably be formed from the EVA. For example, the plastic film is laminated locally, i.e. in regions, onto the sheet of panels, i.e. onto the side of the sheet of panels, as a result of which the sheet of panels can be particularly well reinforced.

[0013] The feature that the sheet is provided with at least one coating, in particular exclusively, locally, i.e. regionally, on its side facing away from the other sheet and the film, is to be understood as meaning that the coating is provided, in particular exclusively, in at least one or exactly one first partial region of the sheet, wherein the sheet has at least one or exactly one second partial region, which in particular directly adjoins the first partial region and is free of coating. In other words, on the one side, the sheet has a surface that is particularly facing the interior of the vehicle. The aforementioned first partial region of the sheet is the first partial region of the surface, so that the coating is arranged in the first partial region of the surface. The aforementioned second partial region of the sheet is the second partial region of the surface, wherein the second partial region in particular directly adjoins the first partial region. In the second partial region, the surface of the sheet is free of coating. Therefore, the surface or the sheet is only partially provided with a coating on the one side. In this way, an effective and weight- and cost-effective reinforcement of the sheet can be achieved.

[0014] Another embodiment is characterized in that the coating is formed from plastic foam. As a result, a particularly high degree of robustness can be achieved.

[0015] In order to be able to reinforce the one-piece panel particularly effectively by means of the plastic foam, in a further embodiment of the invention it is provided that the plastic foam is a polyurethane foam, thus a PU foam.

[0016] In another embodiment, the recess is designed as a blind hole. Thus, excessive weakening of the one sheet can be avoided. A blind hole is an opening which does not completely penetrate the one sheet, but is completely bounded by a wall region of the one sheet towards the film and the other sheet. On the one side of the one sheet, the blind hole itself is open, so that, for example, during the production of the arrangement, a light source can be moved from the one side of the one sheet into, in particular inserted into, the blind hole.

[0017] According to the invention, it is further proposed that the light source is connected to a carrier element, also referred to as a light element carrier, via which electrical energy can be supplied to the light source, whereby the light source can provide the light. In particular, the carrier element is or has, for example, a circuit board, via which electrical energy can be supplied to the light source. In order to be able to achieve a particularly high robustness, it is proposed that the coating covers the carrier element in addition to the recess and the light source at least partially projecting into the recess or optionally arranged completely in the recess, in particular towards the interior space and thus overlaps, in particular completely. Thus, for example, the coating not only contacts the carrier element, in particular the surface of the carrier element facing away from the one-piece board, but also contacts the one-piece board, whereby the one-piece board can be advantageously reinforced.

[0018] Finally, it proves to be particularly advantageous if the light source is connected to the sheet of board by gluing. Preferably, the light source is glued into the recess. This is to be understood in particular as meaning that the light source is glued to the sheet of board within the recess. In other words, the adhesive is thus arranged in the recess, by means of which the light source is glued to the sheet of board. Thus, a weakening of the sheet of board caused by the recess itself can be advantageously counteracted, so that a particularly high robustness can be provided.

[0019] The invention also includes a vehicle, preferably configured as a motor vehicle, in particular as a car, which has an arrangement according to the invention. Advantages and advantageous embodiments of the arrangement according to the invention are to be regarded as advantages and advantageous embodiments of the vehicle according to the invention and vice versa. The same applies to the laminated glass according to claim 7.

[0020] In this case, it proves to be particularly advantageous if the coating is arranged outside the visible area (also called see-through area or see-through glass surface) of the laminated glass. The visible area of ​​the laminated glass is the area through which a person staying in the interior of the vehicle can look and thus see the vehicle surroundings. Since it is now preferably provided that the coating is arranged outside the visible area, in particular completely outside the visible area, a person located in the interior of the vehicle cannot see the coating, or the visible area is not undesirably reduced or otherwise adversely impeded by the coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Further advantages and details of the present invention can be obtained from the following description and the accompanying drawings. In the accompanying drawings:

[0022] Figure 1 A partial schematic cross-sectional side view showing an arrangement of a lighting device on a laminated glass of a vehicle; and

[0023] Figure 2 A schematic top view of the arrangement is shown. DETAILED DESCRIPTION

[0024] Figure 1 A schematic cross-sectional side view of a detail of the arrangement of the lighting device 10 on the laminated glass 12 of a vehicle is shown, wherein the interior space of the vehicle is Figure 1 The interior is denoted by reference numeral 13. The interior space 13 is formed by the body of the vehicle, which is preferably designed as a self-supporting body and is preferably designed as a motor vehicle, in particular a passenger car.

[0025] The laminated glass 12 is, for example, part of a roof element, also referred to as a glass roof, which is constructed separately from the vehicle body and connected to the vehicle body. The laminated glass 12 has a first plate 14 configured as a first glass sheet and a second plate 16 configured as a second glass sheet, which overlap each other at least in a corresponding overlapping area. The laminated glass 12 also includes a film 18, preferably a plastic film, which is arranged between the plates 14 and 16, in particular between the overlapping areas, so that the plates 14 and 16 and the film 18 overlap each other at least in the corresponding overlapping areas. The plates 14 and 16 formed as glass sheets and the film are light-transmissive, so that light from the vehicle environment 20, such as sunlight, can penetrate the plates 14 and 16 and the film 18 and, in particular when the interior space 13 is not shaded, can enter, i.e., be transmitted into the interior space 13.

[0026] Combination Figure 2It can be seen that in this arrangement, the lighting device 10 has a light source 22 configured to provide light. For example, the respective light source 22 is electrically operable, so that by providing electrical energy to the respective light source 22, the respective light source 22 can provide light or emit light. People located in the interior space 13 can visually perceive the light provided by the light source 22.

[0027] Figure 1 An example of one of the light sources 22 is shown, the respective light source 22 being at least partially arranged in a corresponding recess 24 of the plate 16. Figure 1 and Figure 2 In the embodiment shown, the respective light sources 22 are completely arranged in the respective corresponding recesses 24 of the plate 16. For example, the respective light sources 22 are light emitting diodes (LEDs). Figure 1 As can be seen, the respective groove 24 is a blind hole which does not penetrate completely through the laminated glass 12, but only through the plate 16. The respective groove 24 itself, i.e. viewed individually, is open towards the interior space 13, and is therefore open at its respective end facing away from the film 18 and the plate 14. Thus, for example, the respective light source 22 can be moved into the respective corresponding groove 24 through this open end of the respective corresponding groove 24 and thus arranged in the respective corresponding groove 24. The respective groove 24 is configured as a through hole which penetrates completely through the plate 16, and is therefore open at its respective end facing away from the film 18 and the plate 14 and at its respective end facing the film 18 and the plate 14, when viewed individually. For example, the respective groove 24 is configured as a hole, i.e. configured by mechanically drilling the plate 16 in the plate 16.

[0028] exist Figure 1 and Figure 2 In the embodiment shown, the respective light sources 22 are connected to the plate 16 and thus to the laminated glass 12 by bonding. For this purpose, for example, the respective light sources 22 are, in particular, bonded directly to the plate 16. In this case, it is particularly conceivable that the respective light sources 22 are bonded into respective corresponding recesses 24 and thus connected to the plate 16. The respective light provided or can be provided by the respective light sources 22 can be fed into the plate 16 and, for example, fed via the plate 16, i.e. coupled into the laminated glass 12, in order to then illuminate the interior space 13, for example, by means of the light provided by the light sources 22. An advantageously high lighting intensity can be achieved by a correspondingly large number of light sources 22.

[0029] from Figure 1It can be seen that the plate 16 is arranged on the respective inner sides of the film 18 and the plate 14 facing the interior space 13, so that the plate 16 is an inner plate, that is, a plate close to the inside. The plate 14 is arranged on the respective outer sides of the film 18 and the plate 16 away from the interior space 13, so that the plate 14 is an outer plate, that is, a plate close to the outside, of the laminated glass 12. In particular, the film 18 serves as an anti-shatter device, so that the laminated glass 12 is designed as a laminated safety glass (VSG), that is, a laminated safety glass plate. The film 18, which is also called a laminated film, is preferably formed by PVB (polyvinyl butyral). In particular, the plates 14 and 16 and the film 18 are connected to each other by lamination. Therefore, the laminated glass 12 is a roof glass plate with a composite structure of lighting technology, which is realized by the lighting device 10.

[0030] The respective grooves 24 themselves lead to a weakening of the plate 16 , so that the greater the number of light sources 22 , and thus the greater the number of respective grooves 24 , the more the plate 16 is weakened by the grooves 24 .

[0031] In order to achieve a particularly high robustness of the pane 16 and thus of the laminated glass 12 and at the same time to be able to maintain a particularly low shattering sensitivity of the pane 16 and thus of the laminated glass 12, the pane 16 is provided on its side 26 facing away from the film 18 and the pane 14 and facing the interior 13, also referred to as the inner side, with a coating 28 which completely covers the recess 24 and the light source 22 towards the interior 13. Figure 1 and Figure 2 In the embodiment shown, the coating 28 is a common, in particular uninterrupted and therefore continuous coating / material layer for the light sources 22 and the recesses 24, by means of which the light sources 22 and the recesses 24 are each completely covered towards the interior 13. In an alternative embodiment not shown in the figures, it is provided that the respective light sources 22 and the respective corresponding recesses 24 are assigned their own coating, also referred to as a separate coating, which is arranged on the inner side of the plate 16, wherein the respective light sources 22 and the respective corresponding recesses 24 are completely covered towards the interior 13 by the respective assigned separate coating. In this case, for example, these separate coatings are not connected to one another, i.e., in particular, are each completely spaced apart from one another.

[0032] from Figure 1As can be seen, the light source 22 is connected to a carrier element 30, which is also referred to as a light element carrier. The light source 22 can be provided with the above-mentioned electrical energy via the carrier element 30, by means of which the respective light source 22 can provide light. In particular, for example, the carrier element 30 has a line connection to which a line, which is configured, for example, for conducting electrical energy, can be connected, in particular electrically connected, preferably also mechanically connected. Thus, electrical energy can be transferred from the line to the line connection and provided to the respective light source 22 via the line connection and the carrier element 30. In this case, the carrier element 30 is also covered, in particular completely covered, by the coating 28 toward the inner space 13.

[0033] The coating 28 directly contacts a first partial region T1 of the inner side of the plate 16 , and the coating 28 directly contacts a side S of the carrier element 30 facing the interior 13 and facing away from the film 18 and the plate 14 , so that the partial region T1 and the side S are covered, in particular completely covered, by the coating 28 toward the interior 13 .

[0034] The coating 28 advantageously strengthens the pane 16, so that the breakage sensitivity of the pane 16 or the laminated glass 12 as a whole can be kept low. The coating 28 is preferably formed from a plastic, which can be ethylene vinyl acetate (EVA). In this case, it is particularly conceivable that the coating 28 can be designed as a further film 18, in particular a further film provided in addition to the film 18, which can preferably be formed from the plastic, in particular ethylene vinyl acetate. Alternatively, it is conceivable that the coating 28 is formed from a plastic foam, in particular a polyurethane foam (PU).

[0035] from Figure 1 and Figure 2 It can be seen particularly clearly that the pane 16 is provided with the coating 28 only partially on its inner side. This means that the pane 16, in particular the side 26, is provided with the coating 28 in at least one or exactly one first region B1, so that the region B1 is covered by the coating 28 toward the interior 13, wherein the pane 16, in particular the side 26, has at least one or exactly one second region B2, in particular directly adjoining the first region B1, which is free of the coating 28 and is therefore not covered by the coating 28 toward the interior 13. As a result, the reinforcement of the laminated glass 12 by the coating 28 can be achieved in a cost-effective and weight-effective manner.

[0036] exist Figure 2 In the figure, the visible area of ​​the laminated glass 12, also called the glass perspective surface, is denoted by SB. People in the interior space 13 can visually perceive the visible area SB and can in particular see through the visible area SB, so that they can see the surrounding environment 20 from the interior space 13 through the visible area SB. Figure 2It can be seen that the coating 28 is completely arranged outside the visible area SB, so that a person located in the interior space 13 does not visually perceive the coating 28, that is, cannot see the coating 28. Therefore, adverse visual obstruction can be avoided. In particular, the first area B1 provided with the coating 28 adjoins the visible area SB outwardly in the vehicle transverse direction and / or the vehicle longitudinal direction, so that, for example, the first area B1 provided with the coating 28 is a surrounding plate section.
