    Light module with two or more reflectors for a motor vehicle
    The invention relates to a light module for a motor vehicle or for a motor vehicle headlight, wherein the light module has at least two or more light sources, which are positioned in defined positions to each other, and wherein the light module further comprises two or more reflectors, each light source at least one Reflector is assigned.
    Furthermore, the invention relates to a vehicle headlight with one or more such light modules. Often, two or more independent LED light sources are provided on an LED board, each LED light source is assigned its own reflector. For logistical and storage reasons, double or multiple reflectors are often used for such applications. Due to the design of two or more reflectors in a component of the logistical effort can be significantly reduced. Also can be realized in this way a cost savings, since only one tool must be built. It is often necessary due to optical requirements that each LED light source is referenced relative to its reflector, that is positioned and / or aligned accordingly.
    In the case of double or multiple reflectors, however, it is only possible to reference one of the reflectors with respect to its LED light source, while the position of the other reflectors 2/23 P12743 ··

    then determined by the position of this referenced reflector. Referencing all reflectors to their LED light sources is not possible.
    An assembly of the LED board with the LED light sources after attaching the double or multiple reflectors, so referencing the LED light sources to the reflectors (and not vice versa) represents an unusable in practice approach.
    Accordingly, individual reflectors are often used in practice, or there is no referencing of the individual reflectors but a setting on the production line via the optics / lighting technology, i. the reflectors are brought into a position which produces the desired light image and in this position the reflectors are fixed. However, this complex adjustment mechanisms and adjustment systems are necessary, which are often very faulty.
    It is an object of the invention to enable optimum referencing of two or more reflectors with respect to their associated light source, while logistics and storage compared to the use of individual reflectors should be significantly simplified.
    This object is achieved with a light module mentioned in the introduction in that, according to the invention, at least one of the reflectors is movably connected to at least one adjacent reflector.
    According to the invention, a double or multiple reflector is provided, in which at least two reflectors are movably, ie flexibly connected, so that at least these two reflectors are positioned independently of each other to a certain extent can also be optimally referenced to their respective associated light sources.
    It is advantageous if at least one reflector is movably connected to all adjacent reflectors. For example, for three reflectors, the " middle " Reflector movably connected to both adjacent reflectors.
    It is particularly advantageous if each reflector is movably connected to its adjacent reflectors. With n reflectors, then (η - 1) there are mobile connections between the n reflectors.
    In this way, each reflector can be referenced.
    In a concrete embodiment of the invention, it is provided that the mutually movable reflectors are arranged side by side, i. E. the plane (s) in which the reflectors are positioned lie, typically in the installation position of the light module, essentially horizontally. Typically, all the reflectors (and light sources) lie in one plane, but two or more, preferably parallel, planes may also be provided.
    The term "sideways " adjacent to each other refers to the plane (s) in which the reflectors are arranged (in the following, only the "plane" is referred to, although parallel planes may also be meant). If this plane, which is usually formed by an LED board, is horizontal, so the reflectors are actually side by side. If, for example, the LED board is installed at 90 ° to the horizontal, ie vertically, the reflectors are still 4/23 "laterally with respect to the board. arranged side by side, in installation position they are but one above the other. Of course, this is meant by the term "sideways " to be included.
    Preferably, the interconnected reflectors are arranged in a plane movable relative to each other. This plane is preferably that plane (or parallel thereto) in which the reflectors are mounted, or this plane is parallel to the planes in which the reflectors are mounted.
    The term "in one level" means movably mounted, that - when (mentally) fixed in this plane first reflector or the other movably mounted on this first reflector reflectors can only be displaced / shifted parallel to this plane, to the extent that allows the connection between the reflectors. A relative movement of the reflectors normal to this level to a small extent may be possible.
    This is a concrete embodiment, in which the reflectors are movable parallel to the above-mentioned plane to each other, normal to this plane, no or little movement is possible.
    But it can also be deliberately provided that in addition a movement in the direction normal to this plane is possible, or even only a movement in this direction is possible. Thus, a reflector chain would be conceivable in which some reflectors are parallel to the LED board adjustable to each other, while other reflectors are normal to each other movable. This would be approximately in a staircase-like arrangement of
    Reflectors conceivable. P12743 «t ···· ···· · ··· · t ························································································ · · · ····
    In principle, arrangements can thus be realized in which the reflectors are arranged laterally next to one another and / or at an angle to one another and / or one above the other or one below the other.
    In a simple realization of the invention, however, all movable reflectors are movably mounted in a common plane.
    In a specific embodiment of the invention, it is provided that movably connected reflectors are interconnected by means of at least one hinge.
    In order to increase the stability of the flexible connection, movably connected reflectors are preferably connected to one another by means of two or more, preferably by means of exactly two hinges.
    For example, it is provided that the at least two hinges to a plane in which the reflectors are mutually movable, have different normal distances. For example, if the above-mentioned plane is horizontal, then the hinges are superimposed.
    Preferably, the one or more hinges are formed as a plastic hinge or as plastic hinges. For ease of manufacture and for the stability of the double or multiple reflector, it is advantageous if the one or more hinges is / are integrally formed with the reflectors. 6/23 P12743 »· ··············································································· ·· · V * ·· «- • 6 - ·· ..........
    It has proven to be particularly suitable for the invention if the one or more hinges are / is formed as a film hinge or as film hinges.
    In a specific embodiment of the invention, it is provided that the reflectors are designed as plastic reflectors. In particular, this embodiment is suitable for a one-piece production of the entire dual or multiple reflector according to the invention.
    Of particular importance is the present invention for light modules in which the at least one light source is an LED light source, each LED light source comprising one or more light emitting diodes. Especially with LED light sources, an exact referencing of the reflectors to the light sources is important.
    For positioning / Ref erzieren and / or attaching the reflectors to the support plate preferably have the reflectors on their in the attached state of a support plate for the LED light sources facing sides fastening elements and / or Referenzierele-elements, by means of which the reflectors on corresponding fasteners or Referencing the carrier plate can be positioned.
    For example, the fastening elements and / or referencing elements of the reflectors are designed as pins (protruding from the reflectors).
    The fastening elements and / or referencing elements on the carrier plate are preferably designed as holes corresponding to the protruding pins, preferably as through-holes. 7/23 P12743 P12743 • · · · · · · · · · · ············································

    FIG. 1 shows a light module 1 for a motor vehicle or for a motor vehicle headlight, wherein only the components relevant to the invention are shown in the figures. 8.23
    In the embodiment shown, the light module 1 has two light sources 10, 11, wherein the two light sources are LED light sources. One of the two LED light sources 10 in this example comprises one LED, while the other LED light source 11 comprises three LEDs.
    For example, the LED light source 10 serves to generate a first light distribution (or a first part of a light distribution) while the LED light source 11 serves to generate a second light distribution (or a second part of a light distribution).
    The two LED light sources 10, 11 are positioned in defined positions relative to each other, and each of the two LED light sources 10, 11 is associated with a reflector 20, 21, via which the light emerging from its associated LED light source 10, 11 in the light
    Outdoor space is broadcast.
    The LED light sources 10, 11 are mounted on a support plate 2, which is an LED board 2. The LED board 2 itself is mounted on a heat sink 3, for example, board 2 and heat sink 3 are glued together.
    According to the invention, the two reflectors 20, 21 now form a double reflector in that they are movably connected to one another. The double reflector is shown in Figure 2 again in another view together with the board 2.
    In the illustrated embodiment, the two reflectors 20, 21 are arranged side by side laterally and are accordingly connected to each other in their side areas movable. PI2743 • · 9 · ·

    The movable connection of the two reflectors 20, 21 is preferably carried out with hinges 30, 31, as can be clearly seen in particular in Figures 3-5. In the embodiment shown exactly two hinges 30, 31 are provided, which lie one above the other in the installed position of the light module 1.
    According to the invention, a double or multiple reflector is provided, in which at least two reflectors are movably, ie flexibly connected, so that at least these two reflectors can be positioned independently of one another to a certain extent and thus can also be optimally referenced to the respectively associated light sources.
    The hinges are preferably formed as film hinge 30, 31.
    Typically, the hinges 30, 31 are formed integrally with the two reflectors 20, 21. From the production, it is particularly favorable if the reflectors and the hinges are made of a plastic, so that a simple one-piece production can be realized and given a corresponding flexibility of the hinges by the plastic.
    For positioning / referencing of the reflectors 20, 21 on the board 2, the reflectors 20, 21 at their in the mounted state of the board 2 facing sides Referenziere-elements 201; 211 on. For this purpose, the reflectors 20, 21 preferably have a base region 20 ', 2Γ, on which the referencing elements 201; 211 attached, for example, integrally formed therewith. 10/23 P12743 • ···················································································································································································································· ····· ····· - ίο - ..............
    The referencing elements 201; 211 of the reflectors 20, 21 are in this case as from the reflectors or from the reflector sockets 20 ', 21' projecting pins 201; 211 trained.
    Furthermore, fastening elements 200, 210 are attached to the reflector pedestals 20 ', 21', preferably integrally formed with the pedestals, by means of which the reflectors 20, 21 can be fastened to the circuit board 2.
    The Referenzierelemente 201, 211 and fasteners 200, 210 are formed as from the sockets 20 ', 21' protruding pins. As can be clearly seen in FIG. 6, in the present embodiment, the pins 200, 210 are made thicker than the pins 201, 211.
    With the Refenzierstiften 201, 211, the two reflectors 20, 21 of the double reflector can be referenced to the board 2 in the desired position.
    The reference system on the carrier plate or board 2 is thereby bored, preferably through-holes 2 ", 21". formed in the board 2, in which the reflectors 20, 21 are positioned with their Referenzierstiften 201, 211.
    In a concrete manufacturing method, the LED light sources are first placed on the board 2, their position measured (e.g., by optical measurement), and then the reference holes 2 ", 2 " for exact positioning of the reflectors 20, 21 or their Referenzierstiften 201, 211 generated. 11/23 PI2743 ··········· ······································
    The two holes 2! &Quot; are designed as slots, so that a tolerance compensation for an inaccurately manufactured reflector is possible. However, if the reflector is very precisely made, the holes 2 " be formed circular.
    The reflectors 20, 21 or their reflective surfaces are preferably on those referencing pins 201, 211, which the circular, exactly to the Referenzierstifte adapted holes 2 " are assigned, coordinated.
    The bores 2 'in the board 2 are assigned to the fastening pins 200, 210 of the reflectors 20, 21 (see FIGS. 7 and 8). After the reflectors are inserted in their respective intended position, the pins 200 and 210 are caulked in the holes 2 'hot. The reflectors are thus fixed at the optically optimal position for each of them.
    Through the movable connection of the two reflectors 20, 21, it is only possible that both reflectors, although they are integrally formed with each other and thus form a structural unit, can be brought into their intended position, which in rigidly interconnected reflectors only in rare Exceptional cases would be possible.
    The reference holes 2 " as well as the slot 2 '" should match as closely as possible with the diameter of the reference pins 201, 211 together. The holes 2 'can easily have a slightly larger diameter than the pins 200, 210. The heat staking the reflector is finally attached as a rivet, so that a greater clearance between the holes 2' and the thick pins 200,210 (which also as Domes are called) is unproblematic. 12/23 -12- P12743 • · I 4 • ·
    Drill holes 2 ", 2 " ' Do not necessarily have the same normal distance to their LED light source, since it may be desirable that the reflector is slightly rotated about the vertical axis aligned to the LED light source.
    In another embodiment, not shown, holes 2 ", Ί! &Quot; and the pins 201, 211 are dispensed with. The reflectors are used with the pins 200, 210 in the holes 2 ', these holes 2' are sufficiently large, so that the pins 200, 210 slightly shifted in the plane of the board 2 and so the reflectors 20, 21 can be optimally positioned , The independent displacement of the reflectors, which is made possible by their movable connection, takes place until an optimal light image is achieved. In this position, the reflectors are fixed, for example, again by hot caulking the pins 200, 210th
    In this variant, the reflectors after insertion into the carrier and before fixing can still be adjusted in position to a certain extent, as far as the flexible connection allows.
    In both variants, the referencing of the reflectors takes place with respect to the carrier plate 2, on which the LED light sources are arranged, so that the reflectors are de facto positioned with respect to the respective associated LED light source. The movable connection of the reflectors ensures that both (all) reflectors can be positioned as intended with respect to their LED light source.
    The board itself is, as already mentioned, usually mounted before attaching the reflectors on the heat sink, about glued to this. In order to provide sufficient space for the pins on the reflectors, the heat sink is also attached to the appropriate 13/23 PI2743 • · • ·
