Description

  • The present invention relates to a light module for a lighting device of a motor vehicle. The light module comprises a semiconductor light source and a heat sink, wherein the semiconductor light source is arranged in a thermal connection to the heat sink. Furthermore, the light module comprises an electrical line for the power supply and / or control of any electronic components of the illumination device.
  • The invention also relates to a lighting device of a motor vehicle, which comprises a housing and at least one light module arranged therein.
  • In a lighting device of a motor vehicle usually a plurality of electrical lines is laid. For better handling of the lines, they can become one Cable harness be summarized. The electrical lines are used for power supply and / or control of any electronic components of the lighting device. In particular, the lines are used for power supply and / or control of an electromagnet, a stepper motor and / or any light source of the illumination device.
  • Electromagnets are used for switching moving parts of a light module, for example, to switch a flap-like aperture arrangement between a first position for low beam and another position for high beam. The diaphragm assembly can be brought by the electromagnet in a certain number of intermediate positions, for example, to realize a dynamic light distribution.
  • Electric motors, in particular in the form of stepper motors, are used, for example, for pivoting the light module relative to the housing of the illumination device in the horizontal direction for realizing a dynamic cornering light and / or in the vertical direction for realizing a headlamp leveling. In addition, stepper motors can be used for rotating roller-type diaphragm arrangements, on the outer lateral surface of which different diaphragm contours are formed. By rotating the diaphragm arrangement, the different contours are moved into the beam path in order to realize a variable light distribution. Any other components of a light module can be moved by means of a stepper motor.
  • A light source of the illumination device may be as a conventional incandescent lamp, as a halogen lamp, as a gas discharge lamp or as one or more Semiconductor light sources, in particular in the form of a light emitting diode (LED), be formed. The light sources are usually part of one or more light modules of the lighting device.
  • Electrical lines that carry a varying current signal, in particular a pulsed current signal, can cause electromagnetic interference that affect the proper functioning of the electrical and electronic components of the light module or the lighting device, as well as other electrical and / or electronic components of the motor vehicle. A clocked current signal is used, for example, in the form of a pulse width modulation for controlling a light source or an electric motor. About the timing of the current signal, the brightness of the light source and the rotational speed of the electric motor can be varied.
  • For EMC shielding, therefore, it is known from the prior art to sheath cables or wire harnesses exposed with a metal shield to shield the electromagnetic interference. To improve the electromagnetic compatibility, the metal shield is usually grounded. The use of cables or harnesses with a metal shield, however, is relatively expensive to manufacture and expensive to handle. The metal shield is relatively expensive and must be brought in a separate step around the line or the wiring harness. Furthermore, for example, a possible minimum bending radius of the lines is limited by the metal shielding. This means that lines provided with a metal shielding can only be laid in a relatively large bending radius. In addition, the metal shield leads to relatively rigid cables or wiring harnesses. Finally one is additional work required to ground the metal shield.
  • Based on this prior art, the present invention seeks to simplify the laying of electrical lines in a light module and cheaper and at the same time to improve the electromagnetic compatibility of current-carrying electrical lines.
  • To solve this problem is proposed starting from the light module of the type mentioned that at least part of the line extends at least through a part of the heat sink.
  • The heat sink serves to dissipate heat that arises during operation of a semiconductor light source. For this purpose, the heat sink must be made of a thermally highly conductive material, in particular of a metal. Heatsinks are available in particular in so-called. LED light modules. According to the invention it has been recognized that the heat sink at the same time also has very good interference-shielding properties due to its material properties. In the light module according to the invention, therefore, the heat sink is used on the one hand to dissipate heat from the semiconductor light source and on the other hand to shield electromagnetic interference generated by the current-carrying electrical lines. On a separate metal shielding of the electrical line can thus be dispensed with, without this would degrade the electromagnetic compatibility.
  • As a rule, a complete shielding of the entire electrical line is not required. It can be under Be sufficient circumstances, if the disturbing electromagnetic radiation of the line is prevented in a certain area of the light module or the lighting device. If necessary, those parts of the line which do not pass through the heat sink can be shielded by means of a separate metal shield of conventional type. Usually this will not be necessary.
  • Due to the running through the heat sink line this can be held by the heat sink in addition in the light module at a defined position, so that can be dispensed with additional, separate holding elements which hold the line with respect to the light module or the housing of the lighting device.
  • Of course, the light module according to the invention may also comprise more than one semiconductor light source, more than one heat sink and more than one line. In particular, it is conceivable to shield more than one electrical line by means of the heat sink. There are a variety of ways to shield the electrical line using the heat sink. In particular, the line can be guided along the heat sink, so that the heat sink shields the electromagnetic radiation emanating from the line with respect to the remaining part of the light module or the illumination device.
  • Overall, the present invention provides a particularly simple light module, which can be handled particularly well as a unit, for a lighting device of a motor vehicle, which additionally also has a particularly good electromagnetic compatibility.
  • According to an advantageous development of the present invention, it is proposed that the heat sink has a main element and a plurality of cooling elements projecting therefrom and spaced apart, wherein the part of the line guided through the heat sink extends through the heat sink between the cooling elements. The cooling elements are preferably designed as cooling fins or as cooling pins. This has the advantage that a heat sink of conventional design can be used and the heat sink does not need to be changed constructively so that it has not only the heat-dissipating and the störungsabschirmenden properties and can be used to shield the line. In addition, the line can be particularly easily introduced from the outside into the heat sink by simply passing through the cooling elements. The main element preferably has a certain areal extent, the cooling elements projecting radially outward with respect to the areal extent of the main element. In order to improve the shielding effect of the heat sink even further, the cooling elements can be bent together after laying the line between the cooling elements on the line. As a result, the heat sink surrounds the passed-through line almost completely. In addition, the line can not fall out of the heat sink and is held by this in the light module at a predetermined position.
  • According to a preferred embodiment of the present invention, it is proposed that the heat sink has a depression in which the part of the conduit guided through the heat sink extends. Advantageously, the heat sink comprises a main element and a plurality of projecting, spaced-apart cooling elements, wherein the recess is formed in the main element.
  • In order to further improve the shielding effect of the heat sink, it is further proposed that the recess is at least partially covered by a printed circuit board on which the semiconductor light source is arranged. In this regard, it may be advantageous if a surface of the board is provided with a metallic coating. Preferably, the surface of the board facing the heat sink and at least partially resting on the heat sink is provided with the metallic coating.
  • According to another advantageous development of the present invention, it is proposed that the heat sink has a bore in which the part of the line guided through the heat sink extends. In this way, a complete shielding of the guided through the heat sink part of the line can be achieved on all sides. The bore can run through the main element and / or through the cooling elements of the heat sink.
  • In order to improve the shielding effect of the heat sink, it is proposed that the heat sink is grounded. This is often the case with light modules anyway, so there is no need for an extra operation to ground the shield for the line.
  • The object of the present invention is also achieved by a lighting device of a motor vehicle, which has a housing in which at least one light module according to the invention is arranged.
  • Further features and advantages of the present invention will be explained in more detail with reference to FIGS. Show it:
  • FIG. 1
    an inventive light module according to a first preferred embodiment;
    FIG. 2
    an inventive light module according to a second preferred embodiment;
    FIG. 3
    an inventive light module according to a third preferred embodiment; and
    FIG. 4
    a lighting device according to the invention according to a preferred embodiment.
  • In FIG. 4 a lighting device according to the invention of a motor vehicle is designated in its entirety by the reference numeral 1. The lighting device 1 is designed as a motor vehicle headlight. Of course, it could also be designed as any motor vehicle light. The headlight 1 comprises a housing 2, which is preferably made of a plastic. In a light exit direction 3, the housing 2 has a light exit opening 4, which is closed by means of a transparent cover 5. The cover 5 is preferably made of a glass or transparent plastic material. It may comprise, at least in sections, optically active elements (for example prisms or cylindrical lenses) which deflect the light passing through the cover 5, in particular may scatter it. Such a cover 5 is also referred to as a diffuser. Alternatively, the cover 5 may be configured without optically active elements, wherein it is then referred to as a clear disc.
  • In the interior of the headlight housing 2, any number of light modules can be arranged, which serve either alone or in combination with each other to produce different headlight and / or lighting functions.
  • In the illustrated embodiment, a first light module 6 is provided, which may be formed for example as a reflection module or as a projection module. The light module 6 serves, for example, either alone or in combination with other light modules to produce a low beam, a high beam, a city light, a highway light, a highway light, a bad weather light, a fog light or any adaptive light distribution. The light module 6 is in FIG. 4 drawn only schematically.
  • Below the light module 6 extends an elongated formed further light module 7, which can serve to generate any lighting function. The light module 7 generates, for example, a position light, a parking light, a daytime running light, a flashing light or the like.
  • Finally, in the headlight housing 2, an inventive light module 10 is arranged, which can serve to generate any headlight and / or lighting function. The light module 10 comprises a semiconductor light source 11, which is designed, for example, as a light-emitting diode (LED). Of course, the light module 10 may also have more than the light-emitting diode 11 shown. Several light emitting diodes 11 are preferably arranged in a so-called LED matrix next to and / or above one another in a plane. The main emission direction of the light-emitting diode 11 is upwards directed. The light emitted by the light-emitting diode 11 strikes a reflector 12, which then deflects the light substantially in the light exit direction 3. The reflector 12 is preferably parabolic or paraboloidal, wherein the light-emitting diode 11 is preferably positioned at the focal point of the reflector 12. Of course, the reflector 12 may also have a shape deviating from a parabolic or paraboloid shape, in particular an arbitrary free form.
  • The light emitting diode 11 is associated with a heat sink 13, which dissipates the heat occurring during operation of the light emitting diode 11. The heat sink 13 is made of a thermally highly conductive material, such as a metal, in particular die-cast aluminum. For better heat dissipation, it is conceivable that the heat sink 13 projects through a corresponding opening in the headlight housing 2 to the outside. The cooling body 13 can be equipped with suitable surface-enlarging cooling elements, for example, with cooling fins or cooling pins, which in FIG. 4 but not shown.
  • In the headlight housing 2, a plurality of electrical lines are laid, which are used for power supply and / or control of any electrical and / or electronic components of the light modules 6, 7, 10 and the lighting device 1. The electrical wires are in FIG. 4 not shown. In particular, the electrical lines for power supply and / or control of the light sources of the light modules 6, 7 and the light emitting diode 11 of the light module 10 may serve. It is also conceivable that the electrical lines for power supply and / or control of electric motors, in particular of stepper motors, for example for pivoting the light modules 6, 10 in the horizontal and / or serve vertical direction. Furthermore, it is conceivable that electrical lines for power supply and / or control of electromagnets are provided, which serve for example for switching a flap-like aperture arrangement of the light module 6. In this way, the light distribution between a low beam and a high beam and possibly other light distributions can be switched.
  • In the prior art, the electrical leads are encased with a metal shield to improve electromagnetic compatibility and to shield EMC interference. However, this is costly and expensive and complicates the handling of the lines. Therefore, it is proposed according to the present invention that at least a part of the lines extends at least through a part of the heat sink 13. This will be explained below with reference to FIGS. 1 to 3 explained in more detail.
  • In FIG. 1 an inventive light module 10 is exemplified. It is conceivable that the light module 10 has, in addition to the illustrated components, further components which, for the sake of clarity, however, can be found in FIG FIG. 1 are not shown. Such an additional component could for example be a reflector 12 or a so-called intent optics made of a transparent plastic or glass material for bundling the light emitted by the light emitting diodes 11 by means of total reflection. However, such a component could also be a projection lens, which projects the light emitted by the light emitting diodes 11, focused light onto the road ahead of the motor vehicle to produce a desired light distribution. The additional component could also be a diaphragm arrangement, which at least a part of the emitted from the LED 11 and shielded by a primary optics bundled light to achieve a shielded light distribution (eg low beam, fog light, etc.).
  • The light module 10 off FIG. 1 For example, there are three light emitting diodes 11. These are arranged on a common board 14. The circuit board 14 is in turn arranged on the heat sink 13, so that a thermally conductive connection results from the light emitting diodes 11 via the circuit board 14 to the heat sink 13. To increase the heat-emitting surface, the heat sink 13 on one of the board 14 opposite side flächenvergrößernde cooling elements in the form of cooling fins 15. The cooling fins 15 are arranged at a distance from one another. They protrude from a main element 19 of the heat sink 13 from this radially downward.
  • In the illustrated embodiment, an electrical line 16 is passed through the heat sink 13 in a gap 17 between two cooling fins 15. In this way, an efficient shielding of the line 16 can be achieved at least in the region of the light module 10. The part of the line 16 running outside the heat sink 13 can either remain unshielded or can be covered with a separate metal shield of a conventional type. Of course, more than one conduit 16 in the one gap 17 or in different spaces 17 can be passed through the heat sink 13. In order to improve the shielding effect by the heat sink 13 even further, it is conceivable that the two cooling fins 15, which extend in addition to the guided through the heat sink 13 line 16 and laterally delimit the gap 17, are bent in the direction of the gap 17 and largely close it , In this way, an almost complete shielding of the Line 16 can be achieved on all sides. In addition, the line 16 is securely held in the heat sink, so that can be dispensed with additional separate holding elements for holding the line 16 with respect to the light module 10 and the headlight housing 2.
  • Of course, it is conceivable that the cooling body 13 instead of the illustrated cooling fins 15 cooling pins or differently configured cooling elements, between which the line 16 can pass through the heat sink 13. It is also conceivable that the cooling fins 15 other than in FIG. 1 shown, have substantially rectangular cross-sectional shape.
  • In FIG. 2 a further embodiment of a light module 10 according to the invention is shown. In this case, the light module 10 has only one light-emitting diode 11. Instead of cooling fins 15, the cooling body 13 has cooling pins 18 which, in the illustrated embodiment, have a rectangular, in particular a square, cross section. Of course, it is conceivable that the cooling pins 18 also have a round, oval or other cross-section. In the illustrated embodiment, a bore 20 is formed in the main element 19 of the heat sink 13, from which the cooling pins 18 protrude radially downward, through which the conduit 16 is passed.
  • In FIG. 3 a further embodiment of a light module 10 according to the invention is shown. In this case, the cooling element 13 no flächenvergrößernden cooling elements, but consists only of a plate-shaped main element 19. The heat sink 13 is grounded. On one of the board 14 with the LED 11 facing side of the heat sink 13, in the illustrated embodiment the top of the heat sink 13, a recess 21 has been introduced, in which the guided through the heat sink 13 part of the conduit 16 extends. The recess 21 is at least partially covered in the finished assembled state of the light module 10 by the circuit board 14, on which the light-emitting diode 11 is arranged. In FIG. 3 the board 14 is shown in the unassembled state. For assembly, the board 14 is lowered down to the top of the heat sink 13 in the position indicated by 14 'and fixed on the heat sink. The board 14 may provide additional shielding enhancement to the conduit 16 through the recess 21. The shielding effect can be further improved by providing at least one surface of the board 14 with a metallic coating. A in the assembled state with the heat sink 13 in contact surface of the circuit board 14, in the example shown, the bottom of the board 14, is in FIG. 3 provided with a metallic coating 22. The coating 22 can be applied in any manner.
  • In the FIGS. 1 to 3 are at the beginning and at the end of the exemplary drawn line 16 electrical or electronic components A and B symbolically drawn. These components A, B can be any energy sources or consumers of a lighting device 1 or of the motor vehicle. As a power source, for example, a vehicle battery, a control device for the lighting device 1 or a control device for one of the light modules 6, 7, 10 are used. As a consumer, for example, serve an electromagnet, a stepping motor and / or any light source.
  • With the present invention, it is possible to electrical Laying cables 16 in a light module 10 simply, quickly and inexpensively while ensuring a particularly effective EMC shielding. In this case, the heat sink 13 is not only used to dissipate heat from the light emitting diode 11, but also serves to EMC shield the line 16. Of course, it is conceivable to lead more than the one shown line 16 through the heat sink 13 to to shield them. It is also conceivable that a light module 10 according to the invention also comprises any combination of different features of the light modules 10 from the FIGS. 1 to 3 having. Thus, for example, the light modules 10 from the Figures 1 and 2 have a grounded heat sink 13. The number and arrangement of the LEDs 11 can be chosen arbitrarily in the light module 10 according to the invention.
