Description

COMPONENT OF GLASS FOR MIRROR THAT PRESENTS A INTEGRATED LUMINOUS FILM FIELD OF THE INVENTION The invention relates to an exterior mirror module for a vehicle with a mirror glass component, wherein the latter has at least one mirror glass and at least one luminous element therein fixed. BACKGROUND OF THE INVENTION. An exterior mirror of this type is known from DE 103 27 072. Behind the glass of the mirror of the outside mirror there is placed a heating film that projects over the heating elements placed in the shape of a nook. On the protruding part of the film that also surrounds the edge of the mirror glass, light-emitting diodes have been placed, the light of which comes out from the front of the mirror glass. SUMMARY OF THE INVENTION Therefore, the present invention proposes to solve the problem of developing an exterior mirror module for a vehicle, in which in a small space at least one luminous element is integrated and that element is connected in such a way that With a small wiring can be mounted simply and safely. This problem is solved with the characteristics of the main claim. For this, at least one of the luminous elements is a luminous film. The or the luminous films are placed behind the glass of the mirror. In the area of luminous films, the metallization of the mirror glass is partially or semi-permeable in some areas. The luminous elements mounted on the outer mirror module are usually electroluminescent films. These luminous elements, for example, together with their electrical connection, are additionally integrated into the heating element in addition to the heating films. The heating films formed in this manner form a component of mirror glass by means of adhesion to the mirror glass and to the mirror glass support. When placing and gluing the mostly thin heater films, the luminous means are simply assembled together with the heating of the mirror. Since the heating and lighting means have joint connection cables or a joint plug, the connection of the exterior mirror module to the vehicle is further simplified. Eventually, in addition to the light films, other luminous means, such as, for example, luminescent diodes, are placed on the heating film. These diodes settle, for example, on the edge of the mirror glass before metallization. BRIEF DESCRIPTION OF THE FIGURES Other features of the invention are apparent from the dependent claims and from the following description of several exemplary embodiments represented schematically. Figure 1 shows a vehicle exterior mirror module seen from the side of the mirror; Figure 2 shows a partial section through an external vehicle mirror module with a film of illumination and direction of the emitted light; Figure 3 shows the heating film an integrated lighting film; Figure 4 shows a partial section through the address film of the emitted light; Figure 5 shows a layout plan with several luminous films. DESCRIPTION OF THE INVENTION Figure 1 shows an exterior mirror module for vehicle, which among other things consists of a mirror housing (1), a mirror glass (11) and a cover (3) of the base of the mirror that does not It is shown. In figure 2 that shows a partial section oriented transversely to the glass of the mirror (11). Here, the mirror glass module (10) is surrounded by a hooked or glued side and later on the mirror housing (1). The module of the mirror glass (10) is placed in the housing (1) in a manner that is usually adjustable. For this glass mirror module (20) sits loosely inside the edging (2). The mirror glass module (10) according to figure 2 includes a support for the mirror glass (50), an adhesive film (40) and a heating film (20) with an integrated luminous film (61-63) and the frame for a mirror glass (51). On the support for the glass of the mirror (50) the glass of the mirror (11) is fixed by means of an adhesive film (40) and an equally adherent heating or combination film (20). The adherent film (40) is for example provided on both sides with a piece of rubber foam or another thin elastomeric body with a layer of adhesive material. During the assembly, the combined film (20) is adhered with a layer of glue on the rear part (13) of the mirror glass (11). On the combined film (20) the adhesive film (40) is again applied, in order to join the mirror glass (11) with the mirror glass support (50). Among other things to mechanically secure the mirror glass (11) in the support of the mirror glass frame (51) surrounds the mirror glass carrier (50). For this, the frame (51) has an outer edge section (54), which rests on the external contour of the mirror glass support (50) and protrudes forward on the outer side of the mirror glass (12). The outer edge section (54) with the outer side of the mirror glass (12) forms an angle less than or equal to 90 degrees. A few millimeters before the outer side of the mirror glass (12) the frame (5) is transformed into a section (53) which is oriented parallel to the outer side of the mirror glass (12).

This section (53) is transformed into an inner edge section (52) which is supported on the outer side of the mirror (12) at an angle of approximately 90 degrees. The frame of the mirror glass (51) and the mirror glass support (50) are irreversibly joined to each other by means of welding or glueing. Figure 3 shows the combined film (20) with a heating strip (30), an integrated illuminating film (61), a directed film of the emitted light (70), two conductive guides (31, 32) and a plug ( 35). The combined film (20) has a wall thickness of about 0.3 to 0.5 millimeters. The thickness of the films is determined by the lighting film portion. The illumination film (61) is a flexible or rigid electroluminescent film, which for example as part of the heating film (20) has at least one self-adhesive layer on the side of the mirror glass (11). In the area in which the illumination film (61) is placed, the metallization is semi-permeable, that is to allow the cold light produced in the illumination film behind the back side (13) of the mirror glass (11), can shine almost unimpeded through the mirror, while the transparency formed by the semi-permeability is not perceptible to the driver who sees through the rearview mirror. This applies at least during the operation of the vehicle when the light film (61) is not energized. The surface of the semi-permeable window (18) of the metallization is smaller than the light emitting surface of the luminous film (61). The edge of the light-emitting surface lies behind the fully metallized area of the mirror. The color of the light of the luminous film (61-63) in question can be adapted to the purposes of use. Between the luminous film (61) and the mirror glass (11) in the exemplary embodiment according to FIGS. 2 and 3, a film for directing the emitted light (70) is placed. This film whose surface is larger than the light emitting surface of the light film (61), is a transparent plastic film, whose thickness is less than one millimeter, see figure 4. Microlines (71) are placed on the film. parallel to each other. Microlines (71) have a wall thickness, which for example is in the range of hundredths of a millimeter. Their distance from each other is, for example, a greater decimal power. The microlaminae (71) with the surfaces on the rear side of the mirror (13) form, for example, an angle of 60 degrees. In addition, the direction of the primary transmission of the light corresponds to the direction of the arrow (72) depending on the purpose of use the angle can be found in a range of 30 to 90 degrees. Within a hole for addressing the emitted light, the angles of the zones of the individual lamellae can vary among themselves. The opening angle (73) between two adjacent microlights (71) usually amounts to 30 to 40 degrees. Figure 5 shows the front side of a combined film (29) with several zones of integrated light film (61-63) without heating strip, conductive tracks and pin. The luminous film (61) serves here as a signal light to indicate the change in the direction of movement. Before this luminous film is placed a directing film of the emitted light, whose microlamines are oriented from top to bottom. The micro-laminates with the glass surface of the mirror (12) form for example angles of to 80 degrees, this measured in a plane parallel to the vehicle's running surface. By means of this conformation a lighting direction is obtained (65) oriented mainly backwards and for example towards the side that moves away from the vehicle, see figure 5. As a consequence, the signaling light is very visible for the traffic that is behind or passing on the side. Due to the orientation of the microlamps, the driver does not notice his lighting. Down next to the luminous film (61) for example rectangular, there is a luminous film (62) provided as a signaling light, whose illumination direction- (66) is oriented towards the conductor. For this the pre-arranged emitted light routing film has a small angle of lamellae of approximately 30 to 40 degrees compared to the surface of the mirror glass. The traffic that is behind does not perceive the light of the signaling lighting. By means of the use of microlamps, the signaling lights can also be rved well under clear sunlight. By means of signaling lights which, for example, encompass several areas of luminous films of different shapes and which can be activated separately, in the form of symbols or letters, the driver can be given different information about the electronic change-over assistant or point monitoring blind. In the upper area of the mirror a luminous film (63) is placed, which fulfills the function of illuminating the surroundings. In the darkness it facilitates the ascent and descent of the vehicle, because it illuminates the surface of the floor that is next to the driver's and / or co-pilot's door. The lighting direction (67) is thus directed downwards. As a consequence it does not disturb the traffic that comes behind. In the exemplary embodiment according to FIG. 3, there is a heating strip (30), with two recess-shaped sections in the middle region of the mirror. This heating strip (30) terminates eg the rear part of the mirror in the lower left zone on the plug (35). Instead of a plug (35), the conductive tracks (31, 32) and the heating band (30) can also end in individual contact terminals, to which current is supplied if necessary in the mirror module outside of vehicle through contact clamps. The conductor tracks (31, 32) extend parallel to the edge (23) of the combined film (twenty) . These are applied to the side of the combined film (29), on which the heating band (39) is also placed. Obviously there is also the possibility of placing the conductor tracks and the individual heater bands in different electrically isolated planes of a combined or heater film (20) of several layers. Additionally on the combined film (20) can for example be placed in the edge zones, connection devices for the lighting elements by electronic control parts of the mirror adjustment mechanism. Eventually the combined film can be reinforced in areas to receive discrete electronic components such as integrated circuits. Contrary to the examples of embodiment, the luminous film (61) together with the conductor tracks (31, 32) optionally placed on a film, can also be fixed separately on the rear part of the mirror (12).

This is for example the case when the rearview mirror is not heated.
