Description

  • The invention relates to an exterior mirror for a motor vehicle having the features of the preamble of patent claim 1.
  • Such an exterior mirror is in the DE 297 02 746 U1 described. Specifically, the exterior mirror has an opening which is horizontally aligned and extends over almost the entire length of the exterior mirror. In the opening, a light guide is embedded, is coupled into the mirror foot side light via light emitting diodes. The light guide is releasably attached via a support member in the exterior mirror housing.
  • Despite the optical fiber to a large extent surrounding exterior mirror housing this is, however, exposed to increased environmental influences. Over time, this will cause the surface of the light pipe to be contaminated and / or damaged in places. In this way, unwanted Lichtauskoppelbereiche, so that optical properties of the light guide can be affected over time.
  • In the DE 10 2010 061 210 A1 a tail lamp for motor vehicles is described. In the described tail light, a disc-shaped light guide is used. By means of primary light sources in the form of light-emitting diodes, light is coupled into the optical waveguide transversely to a light main emission direction and coupled out again in the main light emission direction. Via a secondary light source designed as an incandescent light, light is emitted in the main emission direction from the rear side of the light guide via a reflector. Thus, several light functions, such as brake light and flashing light can be superimposed with the tail light. The light guide is aligned horizontally with its surface extension and provided on its front narrow side with a scattering optics. The rear side of the light guide facing the secondary light source can also be equipped with stepped or prismatic optical elements.
  • From the DE 10 2012 111 276 A1 a tail lamp for a motor vehicle is known in which a light guide is arranged in a light-transmitting housing.
  • The light guide facing inner surface of a lens is partially provided with an opaque coating. Over an exposed area of the opaque coating, the light of the light guide from the rear light can escape to the outside.
  • In the general state of the art known to the applicant, a light guide for better protection is completely surrounded by a transparent plastic housing and installed together with it in a door mirror housing. Due to the complete surrounding of the light guide housing, but creates a high space requirement.
  • The present invention is based on the object to provide an outside mirror for a motor vehicle, in which the space requirement is reduced.
  • This object is achieved with the features of claim 1.
  • Advantageous embodiments or developments of the invention can be found in the dependent claims.
  • The invention is based on an exterior mirror for a motor vehicle, with at least one light guide into which the light of at least one light source can be coupled. In order to realize at least one light function, the coupled-in light can be decoupled again via at least one side of the light guide which acts as a light exit surface. In this case, the light exits through at least one opening of an exterior mirror housing from the outside mirror to the outside.
  • The at least one light function can be, for example, a direction indicator (flashing light) and / or also a daytime running light.
  • The invention now proposes that the light guide is completely or at least almost completely covered with at least one coating.
  • If the at least one coating is translucent, the light guide can be (fully) coated from all sides. If the coating is opaque to light, then at least the side of the light guide acting as the light exit surface must at least be kept free of the opaque coating. The light guide is then almost completely coated with a coating.
  • By coating the light guide can now be dispensed with a surrounding the light guide and protective housing. The light guide can be mounted in the exterior mirror housing only with the coating. This leads to significant space savings. Moreover, this also allows the number of parts to be kept low. Furthermore, this creates the conditions for the opening in the exterior mirror housing, from which the light coupled into the light guide emerges to the outside, to be slit-like.
  • According to a first development of the invention, the coating is transparent.
  • It has surprisingly been found that with a transparent coating, on the one hand, good protection and, on the other hand, high reflection values and thus a high light output of the light coupled into the optical waveguide can be achieved. Moreover, this makes the production of the outside mirror easier. A masking of the front side before application of the coating or a subsequent removal of the applied coating from a side acting as a light exit side of the light guide can be omitted.
  • It has proven to be particularly advantageous to use a transparent coating as a coating. Transparent paints are extremely resistant. In addition, it has surprisingly been found that with a transparent coating, a high degree of reflection and thus a very good luminous efficacy (ratio of coupled-in to coupled-in light) could be achieved.
  • Another development of the invention proposes that the coating is a metallic coating. The metallic coating may preferably be of gold or aluminum. The metallic coating can be achieved with a high light output as well. However, in this case, the side which functions as the light exit surface of the light guide must be kept free of the coating.
  • In order to be able to optimize the protection for the light guide in the case of a metallic coating, it is proposed according to a further embodiment of the invention to additionally apply at least one further coating to the metallic coating.
  • Very good protection can be achieved if the at least one further coating is silicone-containing or a transparent coating, preferably a transparent lacquer.
  • According to another embodiment of the inventive concept, the optical waveguide is plate-like with an areal extension and has an outline in the outline, with a front side facing a direction of travel, a rear side facing away from the direction of travel, an upper side and a lower side.
  • This training helps to be able to form the opening in the exterior mirror slit, resulting in an extraordinary appearance of the exterior mirror. Moreover, the scythe-like design also allows a slight, lateral coupling of light into the light guide on a lateral side, wherein light rays can be guided in part to a pointed end of the light guide and there coupled out against a direction of travel.
  • In order to optimize the protection of the light guide, it is proposed to cover the side of the light guide acting as light exit surface with a transparent cover element.
  • When using such a cover, it has proven to be highly expedient to form at least partially a distance between the side acting as a light exit surface of the light guide and the cover. This improves the lighting properties of the photoconductive device. In particular, this allows a very homogeneous light emission can be achieved.
  • It also contributes to a homogenization of the light emission if, according to another development, a surface of the cover element, which faces the side of the light guide acting as a light exit surface, is frosted at least in some areas. In this case, the observer facing surface of the cover remain smooth and undamaged, which is the overall visual impression of the Exterior mirror improved. The matting, so roughening can be done for example by an etching process or by sandblasting. However, the matting is preferably already on the tool side, ie introduced by appropriate surface design of the tool in the injection molding of the cover in this.
  • In a further expedient embodiment, a rear, one side facing away from the direction of travel of the light guide is provided with a scattering optics. Due to the scattering optics falling light rays can be optimally directed to the light exit surface on the rear side facing away from the direction of travel. The scattering optics may be formed, for example, as a cushion or strip optics.
  • The invention can also be further developed in that light-deflecting impurities are introduced into the light guide at a distance from the front side.
  • In this way, light rays scattered by the scattering optics of the rear side can be refracted and scattered a second time, which contributes to further lighting improvement. Due to the distance from the front side, the surface of the front surface of the light guide, which acts as a light exit surface, can remain intact despite the defects. The impurities need not all be arranged at the same distance from the front side. They may preferably have at least partially different distances from the front side. As a result, the scattering effect is further improved by the impurities.
  • The impurities can preferably be introduced in the production of the light guide in this. The light guide is made of plastic (preferably polymethyl methacrylate = PMMA or polycarbonate = PC) and is produced by injection molding. In the injection molding process, elevations are encapsulated in the mold halves and imaged as impurities in the upper and / or in the lower side of the light guide. The elevations may be pyramidal, for example. On the side of the light guide then correspondingly pyramid-like depressions, which are filled during coating of the light guide with the one or more coatings described.
  • The impurities can also be generated by means of a laser in a three-dimensional process and thus be formed as a laser engraving under the surface of the light guide. The laser engraving can have any shape and orientation. You can, for example, be formed like a line.
  • A highly concise, emanating from the exterior mirror signal effect can be achieved when the opening of the outer mirror housing is slit-shaped, wherein the surface extension of the optical fiber in the mounting position is oriented approximately horizontally and the light guide received front or with a projection of the cover in the opening is. The slot-like design results in particular when the length of the approximately horizontally oriented opening is many times longer than the height perpendicular to the length. The length to height ratio is preferably in the range of about 40 to 60, more preferably in the range of about 45 to 55. Most preferably, the length to height ratio is about 52.
  • Finally, another embodiment of the concept of the invention provides that the optical waveguide is at the back, ie opposite to its emission direction, partially received by a longitudinal groove of an elongated support and horizontally oriented projections are arranged in the outer mirror housing, which slots are located above and below the longitudinal groove intervention.
  • By such a holder, a vibration-free positioning of the light guide can be facilitated in the opening of the exterior mirror housing.
  • However, the invention also relates to a motor vehicle which is equipped with at least one exterior mirror according to the invention and for which protection is also desired.
  • In the following, we will again discuss in detail the preferred materials to be used:

The pages 20 . 21 and 23 each preferably have a flat surface without a radius of curvature, the sides 20 and 21 parallel to each other and perpendicular to the sides 22 and 23 are aligned. Also the back side 22 has a surface without a radius of curvature. It is however with a scattering optics 220 provided, which is formed in the embodiment as strip optics.
  • How out 2 and 3 is clearly visible, is the light guide 2 as a thin, flat element formed with a surface extension FL. The light guide 2 is in the mounted state with its surface extension FL is oriented approximately horizontally, wherein the surface extension through the surfaces of the upper and the lower side 20 and 21 is determined.
  • A side page 24 serves for the lateral coupling of light of two light emitting diodes (LEDs) 5 , which on the circuit board 6 are attached. Preferably, by the LEDs 5 yellow and / or white light in the light guide 2 be coupled. Thus, for example, the light functions of a direction indicator (turn signal) and / or a daytime running light can be realized. For this purpose, the LEDs 5 be designed as so-called RGB LEDs, with which light of different colors can be generated.
  • For cooling the LEDs 5 is the circuit board 6 with a first heat sink 71 and a second heat sink 72 the cooling 7 connectable. About a fixing screw 73 can be an additional attachment of the cooling 7 in the housing lower part 10 respectively.
  • The light guide 2 rejuvenates, starting from the side 24 , steady to a sharp end 25 , As a result, the mountability of the light guide 2 in the slot-like opening 12 , especially in one of the mirror 15 remote area of the opening 12 facilitated.
  • Specifically, from the 2 and 3 it can be seen that the light guide 2 in the longitudinal direction in three sections 26 . 27 and 28 is divisible. The section 26 takes about 50 to 70 percent of the longitudinal extent of the light guide 2 one. The next section 27 is comparatively short and takes as a transition to the section 28 only about 5 to 10 percent of the length of the light guide 2 one. Finally the section follows 28 , which is about 20 to 30 percent of the length of the light guide 2 claimed and up to the pointed end 25 enough. The light guide 2 is in his section 26 thickest and preferably has a thickness in the range of about 4 to 8 millimeters. The section 27 preferably has about a thickness of preferably about 4 to 7 millimeters, while the section 28 a thickness of preferably only about 3 to 6 mm.
  • As is indicated by way of example by means of light beams L1, L2 and L3, the LEDs are used 5 in the light guide 2 coupled light L through the scattering optics 220 the back side 22 decoupled in direction of travel F (see L1, L2) and exits the light guide 2 via the front side acting as light exit surface 23 outward. However, light rays (see L3) can also be due to total reflection to the pointed end 25 of the light guide 2 directed and there against the direction of travel F back under a certain, possibly prescribed radiation angle emitted.
  • On the front side 23 of the light guide 2 is the serving as a lens, already mentioned cover 4 applied, preferably glued.
  • The cover element 4 has a facing in the direction of travel F front 41 on, which is also smooth. In contrast, a back of the cover 4 with a groove-like depression 40 educated. The gutter-like depression 40 extends over much of the length of the cover 4 , Whose surface may have a matting, so roughening. This was preferably already the tool side during the injection molding of the cover 4 generated.
  • As already mentioned, both the light guide 2 as well as the cover 4 from a thermoplastic molding compound, preferably polymethylmethacrylate (PMMA) are produced by injection molding. Particularly preferred is a material for the light guide 2 (in the following material 1) selected, which has a very good Lichtstreuvermögen with high light transmission, with the following characteristics: characteristic value unit preferred characteristic value, for example Tensile module (1mm / min, ISO 527 ) MPa 3400 Breaking stress (5 mm / min, ISO 527 ) MPa 65 Elongation at break (5mm / min, ISO 527 ) % 2.5 Charpy impact strength (23 ° C, ISO 179 / 1eU ) kJ / m 2 17 Vicat softening temperature (B / 50, ISO 306 ) ° C 105 Glass transition temperature ( ISO 11357 ) ° C 108 Heat distortion temperature (0.45 MPa, ISO 75 ) ° C 101 Heat distortion temperature (1.8 MPa, ISO 75 ) ° C 97 Coefficient of linear expansion (0-50 °, ISO 11359 ) E-5 / ° K 6.3 Melt volume rate MVR (230 ° C / 3.8 Kg, ISO 1133 ) cm 3 / 10min 4.1 Transmittance (D65, ISO 13468-2 ) % 81 density g / cm 3 1.19
  • As the material 1 with the preferred properties of a df23 7N available material under the trade name PLEXIGLAS ® Satinice was used.
  • The cover element 4 By contrast, it consists of a material mixture, wherein in addition to the material 1, preferably another material (hereinafter material 2) is used, which has very good mechanical properties, high heat resistance, good flowability and melt viscosity. Here, the following characteristics have proved to be extremely useful: characteristic value unit preferred characteristic value, for example Tensile module (1mm / min, ISO 527 ) MPa 3200 Breaking stress (5 mm / min, ISO 527 ) MPa 73 Elongation at break (5mm / min, ISO 527 ) % 3.5 Charpy impact strength (23 ° C, ISO 179 / 1eU ) kJ / m 2 20 Vicat softening temperature (B / 50, ISO 306 ) ° C 103 Glass transition temperature ( ISO 11357 ) ° C 110 Heat distortion temperature (0.45 MPa, ISO 75 ) ° C 100 Heat distortion temperature (1.8 MPa, ISO 75 ) ° C 95 Coefficient of linear expansion (0-50 °, ISO 11359 ) E-5 / ° K 8th Melt volume rate MVR (230 ° C / 3.8 Kg, ISO 1133 ) cm 3 / 10min 6 Transmittance (D65, ISO 13468-2 ) % 92 Refractive index (589nm / 23 ° C, ISO 489 ) 1.49 density g / cm 3 1.19
  • As the material 2 with the preferred properties of a commercially available under the trade name PLEXIGLAS ® 7N material was used.
  • As a mixing ratio of the two materials, a mixing ratio of about 75% of material 1 to about 25% of material 2 is particularly preferred (that is, material 1: material 2 corresponds to about 3: 1). Both materials are before processing as amorphous thermoplastic molding compound, in particular as uniform grain.
  • Based on 4 Now, an essential feature of the invention will be explained in more detail.
  • In the assembled state of the exterior mirror 1 is the cover element 4 with the front side 23 of the light guide 2 connected, preferably glued. More specifically, the cover member forms 4 two flanges 42 from where it is with the front side 23 connected is. The width of the flanges 42 is only about 0.3 mm in the exemplary embodiment. So it is in the bonding of the cover 4 with the front side 23 of the light guide 2 ensuring a high dimensional accuracy required.
  • Preferably, an adhesive with the following characteristics is used: characteristic value unit Preferred range, preferred characteristic value, for example ingredients dichloromethane % 30% -60% nitromethane % 15% -40% 2-phenoxyethanol % 5% -10% ethanol % 1% -5% Initial boiling point ° C 40 Density (20 ° C) g / cm 3 1.21 Water solubility (20 ° C) g / l 13.7 Viscosity (dynamic, 20 ° C) mPa 750-1000 stability s 5-30 Time until further processing H > 3
  • As the adhesive with the preferred properties of a commercially available under the brand name ACRIFIX ® 1S 0106 adhesive was used.
  • Between the flanges 42 is the gutter-like depression 40 educated. It can be seen that through the groove-like depression 40 between the front, acting as a light exit surface side 23 of the light guide 2 and the inside of the cover 4 a distance a remains. The distance a is preferably only about 0.1 to about 0.3 millimeters.
  • One of the flanges 42 of the cover 4 protruding projection 43 has a thickness d1 of preferably about 4 millimeters and is in the opening 12 of the housing base 10 added. With d2 is a thickness of the light guide 2 numbered in the illustrated cross section. The thickness d2 is greater than the thickness d1.
  • Both the light guide 2 as well as the cover 4 are made of transparent plastic by injection molding. The transparent plastic can be colored. Preferably, however, the plastic is colorless.
  • It is essential now that the light guide 2 almost completely coated with a coating B1. More specifically, in this embodiment, the out of the cover 4 and the light guide 2 formed unit completely provided with the coating B1. The light guide 2 is therefore only nearly complete (except for the page 23 ) provided with the coating B1.
  • Through the coating B1, the light guide 2 well protected and it can be waived, the light guide 2 inside the exterior mirror housing ( 10 . 11 ) with an additional, space-demanding housing to surround.
  • The coating B1 is also transparent, preferably colorless transparent. Preferably, the coating B1 is formed as a transparent lacquer.
  • In this way it is made possible that the light guide 2 and cover 4 existing unit are optimally protected against contamination and on the other hand surprisingly excellent light values can be achieved despite the coating B1. In particular, a high luminous efficacy can be achieved, which is defined as the ratio of coupled-out light to coupled-in light.
  • The coating B1 can be applied, for example, in a dipping process, in which case the unit to be coated is immersed in the still liquid coating material for the coating B1. It is also conceivable to spray the unit to be coated with the coating material.
  • As transparent coating B1 for the light guide 2 a UV-curing, inorganic-organic hybrid coating has proven itself. This preferably has the following characteristic values or characteristic value ranges: characteristic value unit Preferred range (particularly preferred characteristic value), for example Solids content ( DIN 53 216-A ) % 28-32 (30) Delivery viscosity ( DIN 51 562, part 1 , at 20 ° C) mm 2 / s 4-11 (5-10) Density ( DIN 51 757 , at 20 ° C) g / cm 3 0.9-1.0 (0.95-0.96)
  • As a transparent coating with the preferred properties of a commercially available under the brand name ABRASIL ® FAP-30 MP1 paint was used.
  • The following method steps for the components to be processed (optical fibers 2 and cover 4 ) carried out:
    • • Cleaning of the components to be joined
    • • Apply the adhesive to adhesive surfaces of the components to be joined
    • • joining the components
    • Curing the bonded components for at least about 10 hours at room temperature
    • • Cleaning of the glued components (optical fiber 2 and cover 4 ) existing unit
    • Applying the at least one coating B1 to that of optical fibers 2 and cover 4 existing unit by spray coating
    • Air drying of coating B1 for at least about 10 minutes
    • • curing
  • Before applying the adhesive, the components to be joined are cleaned using a dry polishing cloth. If heavily soiled, they can also be cleaned by means of a commercial cleaning gasoline.
  • The joining of the components is expediently carried out by means of a suitable adhesive teaching. The adhesive previously provided in a syringe can be applied very advantageously by means of a metering needle (for example, 0.5 ", Ø 0.33 mm) on the adhesive surfaces. The bonded components may remain in the gluing unit for curing.
  • Before applying the at least one coating, the assembly consisting of the bonded components is again cleaned by means of a dry polishing cloth. If heavily soiled, it can also be cleaned by means of a commercially available cleaning gas.
  • The application of the at least one coating B1 is preferably carried out by means of a suitable spray gun, since a very accurate coating / coating is possible thereby.
  • The curing of the coating B1 is carried out very effectively by means of a UV drying unit. It has proven to be expedient to generate the UV radiation by means of Hg medium-pressure lamps with about 80-120 W / cm. The UV irradiance is preferably set to about 5-6 J / cm 2 . The duration of an exposure of the coating by means of UV radiation is preferably about 20-30 s. In 5 Now, a second embodiment of the invention is shown, which is in another coating of the light guide 2 reflected. The simplicity is only the light guide 2 complete with cover element 4 shown.
  • Specifically, this is the out of the light guide 2 and the cover member 4 formed unit first coated with a metallic coating B2, wherein prior to coating the unit, the front 41 of the cover 4 was masked or covered. The metallic coating B2 may preferably be a gold coating or an aluminum coating. As a result, light coupled into the optical waveguide can likewise be reflected with low losses in the optical waveguide and coupled out again under a high luminous efficacy.
  • Preferably, such a metallic coating B2 can be vapor-deposited by a PVD process (Physical Vapor Deposition), which makes it possible to apply layers in a vacuum. These include, among other things, the so-called sputtering. However, the coatable layers are extremely thin and are in the nanometer or micrometer range.
  • It is therefore in this embodiment, at least one more coating B3, preferably over the entire unit of optical fiber 2 and cover 4 applied. The coating B3 may preferably be a silicone-containing or else a transparent coating. In the case of a transparent coating, preference is again given to choosing a transparent lacquer. The application is preferably carried out analogously to the application of the coating B1.
  • Based on 6 Now still another embodiment of the invention will be explained. Here is a light guide 2 ' provided, in contrast to the light guide 2 at the top and the bottom side 20 and 21 with impurities 230 is provided. The impurities 230 are at least a certain distance b from the front side 23 in the light guide 2 ' brought in. Thus, the front side 23 remain intact. In addition, the impurities extend 230 essentially over the entire length of the light guide 2 ' , The impurities 230 For example, they can be pyramid-shaped. They were involved in the production of the optical fiber made of plastic 2 ' produced by injection molding over corresponding pyramidal projections of the tool halves. During the subsequent coating with a transparent coating B1 (preferably a transparent lacquer), the impurities become 230 also coated with the coating B1.
  • In this embodiment, the front side was to a 23 Covering cover omitted. Therefore, the light guide 2 ' even with a front area in the opening 12 recorded and against paragraphs 100 the exterior mirror housing 10 supported.
  • In the 7 is hinted that by the impurities 230 one at the scattering optics 220 Reflected light beam L4 is refracted and scattered (L4 ').
  • 8th shows another training in which a light guide 2 '' unlike the light guide 2 ' with impurities 240 provided by the action of a laser (not shown) in a three-dimensional process. The impurities 240 are in the embodiment as a line-like objects in the light guide 2 '' brought in and are under its surface. Other object shapes are conceivable. Again, the impurities have a distance b to the front page 23 on and extend along the length of the light guide 2 '' , By way of example, in turn, a light beam L4 is shown, which initially at the rear scattering optics 220 reflected and at the impurities 240 again broken and scattered (L4 '). Also the light guide 2 '' has been coated after the laser processing of a transparent coating B1.
  • Deviating from this is also conceivable, the light guide 2 ' and 2 '' first with a metallic coating and then again with at least one further, preferably transparent coating to provide.
