Description

[0001] The invention relates to a lamp for a motor vehicle according to the preamble of claim 1. The invention further relates to a motor vehicle with at least one such lamp.

[0002] In a motor vehicle, lights – especially in the vehicle interior – typically perform not only their primary lighting function but also a decorative and aesthetic one. A wide variety of lighting functions – such as functional and ambient lighting – and a multitude of lights in different shapes and designs are known from current technology.

[0003] German patent DE 20 2015 006 022 U1 discloses a luminaire with a light distributor and at least one light coupler with LED. The light coupler couples light into the light distributor.

[0004] From EP 3 792 111 A1, a lamp for a motor vehicle is known which comprises a translucent cover. The cover has one or more light-deflectoring structures which selectively direct the light emitted to a rear side of the cover from a visible side of the cover.

[0005] WO 2016 / 130 375 A1 discloses a lighting arrangement for illuminating an emblem. The lighting arrangement comprises a housing, an emblem, a light source, and an optical light guide. The light from the light source is guided through the optical light guide to the emblem, which is then illuminated.

[0006] Unfortunately, brand logos are often not present on the light fixture, or a brand logo that is present on the light fixture is not particularly highlighted or illuminated.

[0007] The object of the invention is therefore to provide an improved or at least an alternative embodiment of a lamp of the generic type, in which the described disadvantages are overcome.

[0008] This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0009] The present invention is based on the general concept of creating a floating and thus highly attractive illumination of a logo by directing light through a transparent body to the logo and making the areas not associated with the logo opaque. The luminaire according to the invention is intended for use in a motor vehicle and comprises at least one logo light source illuminating in the direction of illumination and at least one main light source illuminating in the direction of illumination. The luminaire also includes a translucent transparent body and a partially translucent aperture. The transparent body is translucent from the logo light source in the direction of illumination, and the aperture is partially translucent from the main light source in the direction of illumination.The aperture has at least one undercut region and is arranged with this at least one undercut region directly adjacent to the transparent body. According to the invention, the aperture is opaque in this at least one undercut region and separates the transparent body from the main light source, at least in certain areas, from the light source.

[0010] The undercut area in the luminaire according to the invention prevents the transparent body from being illuminated and overexposed by the main light source and the aperture by the signet light source. This ensures uniform illumination of the transparent body and the translucent area of ​​the aperture. The transparent body can be made, for example, of glass or plastic. The undercut area is located directly adjacent to the transparent body. In other words, the undercut area can be in contact with the transparent body and / or spaced slightly apart from it. No other components of the luminaire are located between the transparent body and the undercut area. The undercut area of ​​the aperture can at least partially follow the shape of the transparent body.

[0011] The luminaire according to the invention can be used in and on the motor vehicle in all conceivable indoor and outdoor areas. According to the invention, the luminaire bears a logo on its transparent body. This allows the luminaire, in addition to its illumination function, to highlight the logo and aesthetically showcase a brand or product associated with the logo. The luminaire can thus contribute to a positive brand or product image. The luminaire according to the invention can advantageously be customized.

[0012] In a further development of the luminaire, it may be provided that the luminaire has a housing with a housing pot and a translucent cover. The transparent body, the diffuser, the main light source, and the indicator light source can be housed within the housing pot, and the housing pot can be closed with the translucent cover perpendicular to the direction of light transmission. The translucent cover—for example, a cover glass—can be set in a frame, and the frame can be attached to the housing pot. It is also conceivable that the housing pot is made of multiple parts, with several parts being firmly connected to each other by positive locking, frictional locking, or material bonding.

[0013] According to the invention, at least one undercut region of the aperture is funnel-shaped, and the transparent body is accommodated within this funnel-shaped undercut region. Furthermore, the at least one undercut region tapers towards the light source opposite the direction of illumination. A cross-section of the transparent body can increase in size from the light source in the direction of illumination. The shape of the transparent body can correspond to the shape of the undercut region, and in particular to the funnel-shaped undercut region. According to the invention, the transparent body has a circumferential undercut adjacent to the undercut region. This creates the impression that the transparent body is "floating".

[0014] According to the invention, at least one undercut area extends from the signet light source in the direction of illumination and then outwards transversely to the direction of illumination. The aperture can be made of a translucent material, and the at least one undercut area can be formed by an opaque coating. The opaque coating is preferably an opaque lacquer.

[0015] Preferably, the undercut area only partially forms a surface of the aperture, so that the aperture is transparent outside the undercut area. According to the invention, the at least one undercut area surrounds the signet light source transversely to the direction of illumination. This allows the transparent body to be completely separated from the main light source and the aperture to be completely sealed off from the signet light source. This prevents the signet light source from shining through the transparent body and the aperture in their transparent areas from all sides.

[0016] A light diffuser can be positioned between the main light source and the aperture to homogenize the light. The light diffuser can completely or partially separate the aperture from the main light source.

[0017] The signet light source can be formed by at least one signet LED (LED: Light-Emitting Diode) and / or the main light source can be formed by at least one main LED. Preferably, the signet light source is formed by a single signet LED, and the main light source is preferably formed by several—at least two—main LEDs. The main LEDs can then be distributed around the single signet LED. The signet light source and the main light source can be arranged on a mounting board oriented perpendicular to the direction of illumination.

[0018] The signet light source and the main light source can be controlled independently. The signet light source can be designed to emit white light, warm white light, cool white light, and / or colored light. Alternatively or additionally, the main light source can be designed to emit white light, warm white light, cool white light, and / or colored light. This allows the luminaire to be customized and a signet symbol on the transparent body to be particularly emphasized. In particular, color changes, pulsing, displays, warnings, illumination, ambient lighting, and / or lighting effects—for example, entry and exit scenarios—can be implemented.

[0019] In a further development of the luminaire, the transparent body can have a coupling area for coupling in light from the Signet light source, whereby the coupling area can be located directly adjacent to the Signet light source. The term "directly adjacent" means that no other components of the luminaire are located between the coupling area and the Signet light source, and that the coupling area is adjacent to or at a short distance from the Signet light source. The light can be introduced into the transparent body through the coupling area and distributed within it. Additionally, the coupling area can be roughened. This minimizes light losses caused by reflection within the coupling area of ​​the transparent body.

[0020] According to the invention, the aperture has a translucent main viewing area. The main viewing area is arranged directly adjacent to the undercut area and oriented perpendicular to the direction of illumination. In other words, the main viewing area can transition into the undercut area. The undercut area can transition smoothly or in steps into the main viewing area of ​​the aperture. A pattern and / or an information sign, which is at least partially translucent from the main light source, can be arranged in the main viewing area of ​​the aperture. The undercut area and the main viewing area can cover an entire surface of the aperture. The aperture can be made of a translucent material, and the at least one undercut area can be formed by an opaque coating. The opaque coating is preferably an opaque lacquer.The main transparent viewing area of ​​the aperture can then be defined by the transparent material without the opaque coating.

[0021] In a further development of the luminaire, the transparent body can feature a translucent logo viewing area oriented perpendicular to the direction of illumination. Within this logo viewing area, a logo symbol, formed from a combination of translucent and opaque shadow areas, can be positioned. This logo symbol can be associated with a brand or a product.

[0022] A transparent body bearing the logo for the luminaire described above can be manufactured using a specific process. This process involves forming at least the translucent transparent areas and the opaque shadow areas, thereby creating the logo within the translucent logo viewing area of ​​the transparent body. The following section describes in more detail how to manufacture alternative embodiments of the transparent body.

[0023] To produce a first embodiment of the transparent body with the logo, raised areas are formed in the logo's visible area of ​​the transparent body in the direction of illumination. These raised areas are then coated with an opaque coating. The opaque coating can be produced by printing or hot stamping. A separate element is then attached between the raised areas of the transparent body. This separate element can be sprayed onto the transparent body or permanently bonded to it, for example, by gluing, welding, or clipping. The coated raised areas then form the shadowed areas of the logo, and the separate element forms the transparent areas of the logo. In this embodiment, the logo can be particularly emphasized.

[0024] To produce an alternative second embodiment of the transparent body with the logo, the transparent body of the first embodiment is additionally formed from a material that can be coated with an opaque topcoat. The separate element and the opaque coating, on the other hand, are formed from materials that cannot be coated with the opaque topcoat. The transparent body, along with the separate element and the opaque coating, is then selectively coated with the opaque topcoat. The coating is applied after the individual parts have been joined, with the transparent body receiving the topcoat and the separate element and the opaque coating not receiving any topcoat. The opaque topcoat can be applied to the transparent body in an electroplating process.The coupling area of ​​the transparent body, used to couple light from the Signet light source into the transparent bodies, is appropriately kept free of the opaque top coating. This coupling area can be kept clear by stenciling, or the top coating can be subsequently removed – for example, mechanically.

[0025] To produce an alternative third embodiment of the transparent body with the logo, raised areas are formed in the logo's visible area of ​​the transparent body in the direction of illumination. The transparent body is then coated with a semi-transparent coating. This semi-transparent coating can, for example, contain metallic particles such as chromium. The transparent body can be vapor-deposited with the semi-transparent coating or PVD-coated (PVD: Physical Vapor Deposition). An opaque coating is applied between the raised areas of the transparent body. This opaque coating can be an opaque lacquer or a opaque film. The opaque coating can be produced by printing or hot stamping.The raised areas then form the transparent areas of the logo, and the opaque coating between the raised areas forms the shadow areas of the logo.

[0026] To create an alternative fourth embodiment of the transparent body with the logo, an opaque coating is applied to specific areas within the logo's visible area of ​​the transparent body. The opaque coating then forms the shadowed areas of the logo, and areas of the transparent body not coated with the opaque coating form the transparent areas of the logo. In other words, the logo can be represented by the opaque coating applied to the transparent body.

[0027] To produce an alternative fifth embodiment of the transparent body with the logo, the logo, including its transparent areas, shadow areas, and flank areas, is formed, depicted, or applied to a substrate. The substrate can be transparent or translucent, for example. In particular, the substrate can be a carrier film. The logo on the substrate is then deformed in a 3D forming process such that the transparent areas are raised in the direction of illumination and connected to the shadow areas via the flank areas. The 3D-formed logo is then cut out of the substrate. This can be done by punching the logo out of the substrate or by laser cutting. The transparent body, made of a transparent or translucent material, is then sprayed onto the cut-out logo.The fifth embodiment of the transparent body can be manufactured particularly cost-effectively.

[0028] Advantageously, the transparent areas of the logo can be represented by uncoated areas of the substrate. Alternatively, the transparent areas of the logo can be represented by areas of the substrate coated with a clear matte varnish – for example, printed areas. The clear matte varnish advantageously achieves better light diffusion in the transparent areas. Alternatively, the transparent areas of the logo can also be represented by areas of the substrate coated with a translucent and partially light-transmitting silver varnish – for example, printed areas. This allows a metallic impression of the logo to be achieved when the transparent element is not illuminated. The shadow areas of the logo can be formed by an opaque coating.The flanks of the logo can be formed by a metallic layer. This metallic layer can be, in particular, a chromium layer. The metallic layer can advantageously enhance the 3D effect of the logo. The metallic layer can be applied to one side, both sides, or alternating sides of the substrate. Depending on the arrangement of the metallic layer on the substrate, special metallic effects can be achieved.

[0029] The metal layer in the flanking areas of the logo can be produced or applied to the substrate in different ways. Advantageously, the flanking areas can be depicted or shaped on the substrate before or after the transparent areas and / or before or after the shadow areas. Alternative methods for producing the flanking areas with the metal layer are described in more detail below.

[0030] In one approach, the substrate is formed from a non-electroplatable material. Before the 3D forming process, a conductive lacquer is applied to the edges of the substrate. This conductive lacquer can, for example, be printed onto the substrate. The conductive lacquer is then electroplated with the metal layer in an electroplating bath, thus forming the edges of the logo.

[0031] In a second method, the transparent and shadowed areas of the logo on the substrate are covered with a protective layer before the 3D forming process. This layer could be, for example, a stencil or a protective coating. The substrate is then coated with the metal layer. Because the transparent and shadowed areas are covered, the metal layer is applied to the substrate only on the edges. The protective layer is then removed from the substrate. This can be done, for example, mechanically, chemically, and / or thermally.

[0032] In a third option, the substrate material is completely coated with the metal layer before the 3D forming process. Here, the substrate material can be electroplated or vapor-deposited, for example. A protective coating is then applied to the flanks. The metal layer is then removed from the substrate material in areas not covered by the protective coating. For example, the metal layer can be removed by an etching process or a laser. Finally, the protective coating is removed from the flanks.

[0033] A fourth option involves coating the substrate material with the metal layer on its flanks using a transfer process prior to the 3D forming process. This transfer process can be, in particular, an embossing process. In this process, the metal layer is transferred from a metal foil to the substrate material using a die under temperature and pressure. The metal layer adheres to the substrate material via an adhesive layer that is either applied to the metal foil or printed onto the substrate material before the embossing process.

[0034] The invention also relates to a motor vehicle with at least one lamp as described above. The lamp comprises a translucent body and a diaphragm. Furthermore, the lamp has at least one indicator light source for illuminating the translucent body and at least one main light source for illuminating the diaphragm. To avoid repetition, reference is made here to the above explanations.

[0035] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0036] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0037] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0038] Each of these shows, schematically: Fig. 1 a top view of a lamp according to the invention; Fig. 2 a sectional view of the luminaire according to the invention in a Fig. 1 section plane AA shown; Fig. 3 a view of a transparent body of the luminaire according to the invention; Fig. 4-7 Views of the transparent body with the logo symbol in a first embodiment during manufacturing; Fig. 8-12 views of the transparent body with the logo in a second embodiment during manufacturing; Fig. 13-16 Views of the transparent body with the logo in a third embodiment during manufacturing; Fig. 17-19 Views of the transparent body with the logo in a fifth embodiment during manufacturing.

[0039] Fig. Figure 1 shows a top view of a lamp 1 according to the invention for a motor vehicle. Fig. Figure 2 shows a sectional view of the luminaire 1 according to the invention. The luminaire 1 comprises a signet light source 2 with a signet LED 2a and a main light source 3 with several main LEDs 3a. The signet light source 2 and the main light source 3, or the signet LED 2a and the main LEDs 3a, respectively, illuminate primarily in a direction LR. The signet light source 2 and the main light source 3, or the signet LED 2a and the main LEDs 3a, are arranged on a mounting board 4, the mounting board 4 preferably being oriented transversely to the direction LR.

[0040] Furthermore, the luminaire 1 has a transparent body 5 and an aperture 6. The transparent body can be made of glass, for example, or of plastic. The aperture 6 has a funnel-shaped, opaque undercut area 7a and a translucent main viewing area 7b. The undercut area 7a transitions into the main viewing area 7b, which extends outwards from the undercut area 7a perpendicular to the direction of illumination LR. The aperture 6 is made of a translucent material, and the undercut area 7a is formed by an opaque coating, for example, a lacquer. The opaque coating faces the transparent body 5. The transparent body 5 is funnel-shaped and is accommodated in the undercut area 7a of the aperture.Both the undercut area 7a of the aperture 6 and the transparency body 5 taper towards the signet light source 2. The undercut area 7a follows the shape of the transparency body 5 and surrounds the transparency body 5 perpendicular to the direction of illumination LR.

[0041] The transparent body 5 is positioned in the direction of illumination LR after the signet light source 2, and the aperture 6 is positioned in the direction of illumination LR after the main light source 3. The transparent body 5 is illuminated by the signet light source 2, and the aperture 6 is illuminated by the main light source 3. The transparent body 5 is surrounded, transversely to the longitudinal direction LR, by the opaque undercut area 7a of the aperture 6. The undercut area 7a thus separates the transparent body 5 from the main light source 3 and the main viewing area 7b of the aperture 6 from the signet light source 2. Therefore, the transparent body 5 cannot be illuminated by the main light source 3, and the aperture 6 cannot be illuminated by the signet light source 2.

[0042] To homogenize the light from the main light source 3, a light diffuser 8 is preferably arranged transversely to the direction of illumination LR between the main light source 3 and the main viewing area 7b of the aperture 6. Furthermore, the transparent body 5 is arranged with a coupling area 14 facing the signet light source 2. The coupling area 14 is preferably roughened to improve the coupling of light from the signet light source 2 into the transparent body 5.

[0043] Referring to Fig. In the transparent body 5, a signet viewing area 15 with a signet symbol 9 is located. The signet viewing area 15 is oriented perpendicular to the direction of illumination LR and is adjacent to the main viewing area 7b of the aperture 6. A pattern symbol 10 is also located in the main viewing area 7b of the aperture 6. The luminaire 1 can thus, in addition to its illumination function, highlight the signet symbol 9 and aesthetically showcase a brand or product associated with the signet symbol 9. The pattern symbol 10 further emphasizes the signet symbol 9.

[0044] Referring to Fig. The luminaire 1 comprises a housing 11 with a housing pot 12 and a translucent cover 13. The translucent cover 13 can, for example, be a cover glass. The transparent body 5, the aperture 6, the light diffuser 8, and the mounting plate 4 with the signet light source 2 and the main light source 3 are housed within the housing pot 12. The cover 13 is translucent and closes the housing pot 12 perpendicular to the direction of light LR. The cover 13 is set within a frame 21, which securely fastens the cover 13 to the housing pot 12. The housing 11 includes further housing parts 11a, 11b, and 11c, which are firmly connected to the housing pot 12 and to each other.

[0045] Fig. Figure 3 shows a view of the transparent body 5 of the luminaire 1 according to the invention. The transparent body 5 is funnel-shaped and tapers in the opposite direction of illumination LR from the logo viewing area 15 to the coupling area 14. The logo viewing area 15 and the coupling area 14 are arranged opposite each other. The logo symbol 9 is arranged in the logo viewing area 15 of the transparent body 5. The logo symbol 9 is formed from at least a combination of translucent transparent areas 9a and opaque shadow areas 9b. In addition, the transparent body has an undercut 22 that extends around the logo viewing area 15 and is adjacent to the undercut area 7a of the aperture – as shown in Figure 3. Fig. 2 is recognizable - arranged. The undercut 22 can give the logo symbol 9 a "floating" impression.

[0046] Fig. 4, Fig. 5, Fig. 6 to Fig. Figure 7 shows views of the transparent body 5 with the logo symbol 9 in a first embodiment when manufactured using a method 23. Fig. 4 The transparent body 5 is formed with raised areas 16 in the direction of light LR. After Fig. 5. The high areas 16 are coated with an opaque coating 17 by printing or hot stamping, thereby forming the shadow areas 9b of the transparent body 5. After Fig. 6. The transparent areas 9a of the logo symbol 9 are formed by a separate element 18. The separate element 18 is positioned between the raised high areas 16 of the transparent body 5 and is bonded, welded, or clipped to the transparent body 5. Alternatively, the separate element 18 can be injection-molded between the raised high areas 16 of the transparent body 5. In Fig. Figure 7 shows the completed transparent body 5 with the signet symbol 9 in the first embodiment.

[0047] Fig. 8, Fig. 9, Fig. 10, Fig. 11 to Fig. Figure 12 shows views of the transparent body 5 with the logo mark 9 in a second embodiment during production using method 23. The second embodiment of the transparent body 5 is a further development of the first embodiment of the transparent body 5. Thus, in the first embodiment, according to Fig. 4-7 and in the second embodiment according to Fig. 8-10 analogous steps are carried out: the transparent body 5 with raised areas 16 in the direction of illumination LR is formed, the shadow areas 9b of the transparent body 5 are formed, and the separate element 18 is arranged between the raised areas 16 of the transparent body 5. In contrast to the first embodiment, the transparent body 5 is formed here from a material that can be coated with an opaque top coating 19. The separate element 18 and the opaque coating 17, on the other hand, are formed from materials that cannot be coated with the opaque top coating 19. After Fig. 11 The transparent body 5 is then coated with the opaque top coating 19. The separate element 18 and the opaque coating 17 remain free of the top coating 19. The coupling area 14 of the transparent body 5 is also appropriately kept free of the top coating 19. In Fig. Figure 12 shows the completed transparent body 5 with the signet symbol 9 in the second embodiment.

[0048] The Fig. Figures 13-16 show views of the transparent body 5 with the logo mark 9 in a third embodiment when manufactured using method 23. Fig. 13 The transparent body 5 is formed with raised areas 16 in the direction of light LR. After Fig. 14 The transparent body 5 is coated with a semi-transparent coating 20 – for example, with metallic particles such as chromium – by vapor deposition or PVD process. After Fig. 15 The shadow areas 9b of the signet sign 9 between the high areas 16 are formed by the opaque coating 17. Fig. Figure 16 now shows the completed transparent body 5 with the signet symbol 9 in the third embodiment.

[0049] A fourth embodiment of the transparent body 5 with the logo 9 is also conceivable, in which the opaque coating 17 is applied to the flatly shaped logo viewing area 15 of the transparent body 15, thereby forming the shadow areas 9b of the logo 9. The transparent areas 9a of the logo 9 are then formed by areas that are not coated with the opaque coating 17.

[0050] The Fig. Figures 17-19 show views of the transparent body 5 with the logo mark 9 in a fifth embodiment when manufactured using method 23. Fig. 17 The logo 9, with its transparency areas 9a, shadow areas 9b, and flank areas 9c, is formed, applied, or created on a substrate 23. The substrate 24 can, for example, be a transparent or translucent substrate film. The transparency areas 9a, shadow areas 9b, and flank areas 9c can be formed in a different manner.

[0051] The transparency areas 9a of the signet symbol 9 can be formed, for example, by uncoated areas of the substrate 24, or by areas of the substrate 24 printed with a clear matte varnish, or by areas of the substrate 24 printed with a translucent and partially translucent silver varnish.

[0052] The shadow areas 9b of the signet symbol 9 can be formed by the opaque coating 17. The opaque coating 17 can, for example, be printed onto the substrate 24.

[0053] The flank areas 9b of the logo 9 can be formed by a metallic layer, in particular a chromium layer. The metal layer can be applied to the substrate 24 on one side and / or both sides and / or alternately on both sides. The metal layer in the flank areas 9c of the logo 9 can be applied to the substrate 24 in a different manner.

[0054] In one possibility, a conductive varnish can be printed onto the non-galvanizable substrate 24 in the flank regions 9c; and then the conductive varnish can be electroplated with the metal layer. In a second possibility, the transparent regions 9a and the shadow regions 9b can be covered with a mask; the substrate 24 can be vapor-deposited with the metal layer; and then the mask can be removed from the substrate 24. In a third possibility, the substrate 24 can be completely coated with the metal layer; then a protective varnish can be applied to the substrate 24 in the flank regions 9c; the metal layer can be removed from areas of the substrate 24 not covered by the protective varnish; and then the protective varnish can be removed from the flank regions 9c.In a fourth possibility, the carrier material 24 can be coated with the metal layer in the flank areas 9c using a transfer process.

[0055] The flank areas 9c are applied or shaped or formed on the carrier material 24 before or after the transparency areas 9a and / or before or after the shadow areas 9b.

[0056] After Fig. In process 23, the logo 9 depicted on the carrier material 24 is deformed in a 3D forming process such that the transparent areas 9a are raised in the direction of illumination LR and connected to the shadow areas 9b via the flank areas 9c. The 3D-formed logo 9 is then cut out of the carrier material 24 in the correct shape. The logo 9 can be punched out of the carrier material 24 or cut off with a laser.

[0057] In Fig. Figure 19 shows a view of the cut-out logo symbol 9. The logo symbol 9 exhibits the raised transparency areas 9a and the recessed shadow areas 9b. The transparency areas 9a and the shadow areas 9b are connected to each other via the flank areas 9c.
