    METHOD FOR POSITIONING A LIGHT-FORMING BODY
    The invention relates to a method for positioning a light shaping body, e.g. a reflector, relative to at least one light source.
    To generate a desired light distribution in the area in front of and behind a vehicle, a light module for a vehicle headlight or a vehicle headlight has one or more light sources and one or more light-shaping bodies, for example one or more reflectors. Light emerging from the light source is radiated by such a reflector as a desired light image in an area in front of the vehicle, in which the vehicle headlamp is installed.
    In order to be able to produce an optimal and especially law-compliant light image, the exact positioning of the light source in relation to the reflector is of particular importance. For example, when using LED light sources having, for example, one or more light-emitting elements as light-emitting elements, the deviations from the target position may only be in the 1/10 mm range, i. Reflector and LED light source (s) must be positioned extremely accurately to each other.
    In current assembly concepts, the LED light source is first soldered to an LED print (printed circuit board), this print is then attached to a heat sink, e.g. glued to this or screwed to this. The reflector is then mounted on the heat sink.
    Tolerances in the position of the light emitting diodes in relation to the LED housing, LED housing in relation to the LED print, LED print in relation to reference positions on the heat sink, heat sink tolerances per se, tolerance of heat sinks Reflector, reflector tolerances.
    With such a mounting concept, an optimal positioning of the reflector with respect to the LED light sources is correspondingly not possible or only very expensive, in correspondingly complex systems. 2/17 -2- PI2672
    It is an object of the invention to provide a method by means of which an exact and simple positioning of a reflector or a light-shaping body, just as a reflector, a lens, a light guide, a diaphragm, etc. with respect to one or more light sources is possible ,
    This object is achieved by a method mentioned above according to the invention by the following steps: a) attaching the at least one light source on a support plate; b) measuring the position of the at least one light source on the carrier plate; c) attaching one or preferably a plurality of reference positions to the carrier plate, wherein the position of the at least one reference position depends on the position of the at least one light source; d) Referencing, i. Aligning the light shaping body at the reference position or positions on the support plate; and e) attaching the light-shaping body to the carrier plate or with respect to the carrier plate.
    By the method according to the invention, the tolerance chain can be significantly shortened, since only tolerances in the measurement of the position of the light source, tolerances occur in mounting the reference positions and tolerances of the light-shaping body itself. An exact positioning of the light source (s) and the light-shaping body to each other is thereby drastically simplified.
    In an alternative embodiment, the following steps are provided according to the invention: a) attaching one or preferably several reference positions to a carrier plate for at least one light source; b) measuring the position of the at least one reference position on the carrier plate; C) attaching the at least one light source to the carrier plate taking into account the position of the at least one reference position; d) Referencing, i. Aligning the light shaping body at the reference position or positions on the support plate; and e) attaching the light-shaping body to the carrier plate or with respect to the carrier plate.
    In a specific embodiment, in which an exact positioning of the light-shaping body is particularly important, it is provided that the at least one light source is an LED light source having one or more light-emitting diodes, and that the carrier plate is a printed circuit board for the at least one LED Light source is.
    Preferably, it is provided that in step a), the at least one LED light source is soldered to the circuit board.
    In order to enable a simple and exact positioning, it is provided, for example, that in step b) the geometric center of the at least one light source is determined and the reference positions are arranged with respect to this geometric center on the carrier plate.
    The positioning of the light-shaping body can be effected even more optimally if, in step b), the brightest area (or the brightest point) of the at least one light source is determined and the reference positions are arranged on the carrier plate with respect to this brightest area.
    In a specific embodiment of the method according to the invention, it is provided that the position of the at least one light source or the at least one reference position is determined by means of an optical measuring method, preferably with a camera.
    Furthermore, the determination by means of laser technology would be conceivable, which is more accurate but also more expensive. 4/17 -4- PI2672
    In principle, mechanical measuring methods can also be used, although optical measuring methods are preferred.
    Furthermore, it is provided in concrete embodiments that the one or more reference positions in the form of one or more holes, such as slots, and / or in the form of one or more, preferably rectilinear reference edges is / are formed.
    Depending on the application and design of the light-shaping body, the appropriate reference surface / edge / hole is created, which brings the light-shaping body in a well-defined position. An oblong hole serves, for example, to prevent the light-shaping body from being rotated, while, for example, edges limit the movement of the light-shaping body in a specific direction, for example in the direction of the light source.
    For example, it can be provided that reference positions are drilled and / or milled.
    The reference positions can basically be in the form of webs, bores, contact surfaces or contact surfaces, oblong holes, stops, etc.
    Preferably, it is also provided that the light-shaping body is fastened by means of at least one, preferably two fastening elements with respect to the support plate. For a stable attachment is provided in particular that the light-shaping body with the at least one fastening element to a heat sink to which the support plate is attached, is attached.
    For this purpose, the light-shaping body in a specific embodiment, a mounting base, this is attached to the heat sink, so that a special stable connection is formed.
    The support plate itself is attached to the heat sink, for example glued to it, so that a good heat transfer from the support plate is ensured on the heat sink. 5/17 -5- P12672
    In the following the invention is discussed in more detail with reference to the drawing. In this shows
    1 shows a basic structure for the inventive positioning of reference positions on a support plate,
    2 shows the carrier plate of Figure 1 in a detailed view,
    3 a reflector, positioned on a carrier plate, in a side view,
    4 shows the reflector from FIG. 3, in a view from the opposite side,
    5 is a view of the carrier plate from below with positioned reflector,
    Fig. 6 is a view of the support plate with attached reflector obliquely from above, and
    Fig. 7 is a view of a reflector attached to a heat sink with respect to the support plate.
    FIG. 1 shows an arrangement for carrying out a method according to the invention for positioning a light-shaping body, such as a reflector 1, relative to at least one light source 2.
    FIG. 1 shows a carrier plate 3, here a printed circuit board (LED print), on which in a step a) a light source 2 is attached.
    In the variant shown, the light source 2 is an LED light source, which has two light-emitting diodes here. Accordingly, as already mentioned above, the carrier plate 3 is a printed circuit board for the LED light source 2. Preferably, in step a), the LED light source 2 is soldered to the printed circuit board 3.
    FIG. 1 also shows a camera 200, by means of which the position of the LED light source 2 on the carrier plate 3 is determined in step b). 6/17 -6- PI2672
    In this case, in step b), for example, the geometric center of the LED light source 2 is determined, or it is determined in step b) the relevant brightest area (or the brightest point) of the LED light source 2.
    If the LED light source comprises exactly one LED, the brightest point of this LED is decisive for homing or positioning the reference positions.
    If the LED light source comprises two or more LEDs, it depends on the particular application whether the relevant brightest point is that which is generated jointly by all the LEDs of the LED light source or, for example, the brightest point of only one specific, defined LED (eg at 3 LEDs the middle LED) of the LED light source is considered. In the latter case, only the measurement or determination of the brightest point of this one, excellent LED is necessary. It can also be provided that a subset of all LEDs of an LED light source is considered and their jointly generated brightest point is determined.
    In general, therefore, after fitting the LED board with the LED light source, the brightest point or area decisive for the specific application is determined by measuring the one defined, the plurality of defined LEDs or all LEDs.
    It is also conceivable that fixed, for example, from the manufacturer side of the light-emitting diodes or the LED light sources is predetermined, which point is the brightest point or which point should be used as a starting point for referencing.
    In a next step c), a plurality of reference positions 4 for a reflector 1 are attached to the carrier plate 3, wherein the position of the reference positions 4 depends on the position of the LED light source 2.
    The arrangement of the reference positions is preferably carried out taking into account the geometric center of the LED light source 2 or the brightest area of the LED light source 2.
    In the example shown, the reference positions 4, as can be seen in particular in FIG. 2, are an oblong slot 4a open on one side and reference edges or reference planes 4b running rectilinearly 7/17 -7 PI2672. The reference positions 4 are for example drilled, milled or otherwise made, e.g. Laser cutting can also be used.
    Furthermore, a plug housing 5 for the electrical contacting of the LED light source 2 is shown in FIG.
    At these reference positions 4, in a next step d) the reflector 1 is referenced, i. aligned and positioned on the support plate 3, as shown in Figures 3-6 from different views.
    In the illustrated embodiment, the reflector 1 has a mounting base 1 'which is connected to the corresponding formations corresponding to the reference positions 4a, 4b, for example an extension 1a, which is arranged in the slot 4a, as well as base surfaces or base levels 1b, which come to rest on the reference surfaces 4b of the support plate 3, is equipped. (The at least one reflective surface of the reflector 1 is not shown in the figures.)
    In FIGS. 3 and 4, the referencing of the reflector or of the reflector base V at the reference surfaces 4b with its sections 1b can be clearly seen, while FIGS. 5 and 6 show how the reflector 1 or the base 1 'with the projection 1a is positioned in the slot 4a.
    In this way, the reflector 1 is positioned in the desired position with respect to the arranged on the support plate 3 LED light source 1 to the support plate 3 and is fixed in a further step e) to the support plate 3 and with respect to the support plate 3 ,
    By the reference positions 4a, 4b, the reflector 1 assumes the desired position, in this it can be held for fixing, for example, with its own, not shown holding device until it is finally in this position finally (but possibly solvable) fixed, like this is described below by way of example of a concrete embodiment. 8/17 -8- PI2672
    However, it can also be provided that e.g. one or more return elements 7, for example in the form of one or more springs (such as compression springs) are provided which hold the reflector or generally the light-shaping body in its reference position until it is fixed.
    FIG. 7 shows a light module 10 according to the invention in this connection. The return element 7 is arranged between the mounting base 1 'and a section 6b of the heat sink 6 and can be biased, for example, by positioning the reflector 1 in its reference position, so that the reflector 1 is in this position at least temporarily.
    The at least one return element 7 is preferably, as shown, integrally connected to the reflector 1, in particular with its mounting base 1 '.
    Specifically, the heat sink 6, two sections 6a, 6a ', which are, for example, perpendicular to each other. The support plate 3 is arranged on one of the two sections 6a, for example bonded thereto. Furthermore, the heat sink 6 has a stop region 6b for the restoring element 7, which stop region 6b is formed, for example, in one piece with the two sections 6a, 6a '.
    When positioning the reflector 1, the return element 7 abuts against the abutment portion 6b and is compressed, i. the return element 7 is biased between the portion 6b and the mounting base 1 ', so that the mounting base 1' in the reference positions 4a, 4b is pressed. In this way, the reflector 1 is held at least temporarily in this position.
    For fixing the reflector is provided, for example, that the reflector 1 with at least one, preferably as shown with two fasteners 8 on a heat sink 6 (in the example shown on section 6a of the heat sink 6, to which the support plate 3 is attached), is attached , This is shown schematically in FIG.
    Specifically, while the reflector 1 is fixed with its mounting base 1 'to the heat sink 6, so that a stable attachment. 9/17 -9- P12672
    The support plate 3 itself is attached to the heat sink 6, for example glued to this.
    Preferably, the reflector 1 or its mounting base 1 'has a bearing surface, by means of which the base 1' rests on the board. In this way, the distance of the reflector surface to the at least one light source can be reliably adjusted.
    The fasteners 8 are used, for example, as a spring, e.g. designed as a sheet metal spring, which springs are preferably designed in the form of bow springs. The springs are preferably clipped on the heat sink and the mounting base in this embodiment, the base Γ additionally has, for example, as shown in Figure 7 still slot-shaped openings for suspending the fasteners 8.
    For better clarity, the light module 10 is shown here with a dedicated heat sink 6 assigned only to the light module 10 shown. In practice, however, it can also be provided that a heat sink is provided for a plurality of light modules, so that a plurality of carrier plates with light source and light-shaping body are arranged on a single heat sink.
    The invention has been discussed above with reference to a reflector, but the light-shaping body can also be an optical system, such as a lens, a light guide, etc. 10/17
