Description

The invention relates to a lighting device for motor vehicles according to the preamble of claim 1.

Such lighting devices are indoors and outdoors arranged by motor vehicles and serve as interior lighting, reading luminaire and luminaires that are arranged in the area of the doors and at Darkness illuminate the floor around the vehicle to make sure and comfort of the vehicle user during the boarding process increase. Through these known lighting devices can be dirty and possibly under the vehicle sources of danger are more easily recognized. In addition, in particular in a dark environment, the subjective well-being of the driver increased by the lighting of the vehicle environment. Wuh When parking in an unlit environment, the outside can lighting can be used as a parking aid.

In the known lighting devices are considered electrical Bulbs in most cases incandescent and relatively rarely Gas discharge lamps used. These two types of lamps  have for the purpose of illuminating certain areas significant disadvantages in or outside of a vehicle.

The main disadvantage when using incandescent lamps is their operation very high filament temperatures and necessary due to the system thereby concentrated high thermal occurring at one point Charges. In addition, the light bulbs themselves are relatively large and offer only an acceptable luminous efficacy in operation if they are together are installed with an appropriate reflector. The high thermi losses, the size of the light bulbs and the use of Reflectors require a minimum size of such lighting equipment which cannot be undercut. This minimum size complicates the integration of this lighting device in the vehicle existing modules, such as B. the exterior mirror, the interior rearview mirror gel, vehicle sills, bumpers, moldings, covers, consoles, Shelves, glove compartments and ashtrays.

Therefore, in many cases the lighting equipment must be switched on for the Light radiation can be arranged in unfavorable places, because only here required space for mounting the lighting device available is. Since the size relationships are different in each vehicle, cannot use universally usable lighting devices that are inexpensive to manufacture in large series, but it must have a vehicle-specific lighting device for each vehicle type tion are developed and manufactured. Overall, the design game strong in the construction of such lighting devices limited.

Due to the concentrated thermal losses occurring at one point Incandescent lamps cause temperature problems in the area of the Monta of the lighting device. Because of the waste heat the materials of the surrounding assemblies become thermally strong charged. To counteract damage to these materials, expensive, temperature-resistant materials must be used to provide complex measures for heat dissipation. Because this too  If measures were not sufficient in the case of permanent exposure, the maximum amount of waste heat can be limited, including timing and / or Thermal protection devices are to be provided to illuminate switch off before components overheat. After reaching the Maximum heat exposure also requires a long break to recover Cooling of the components.

Because of the high temperature in the filament of incandescent lamps these are prone to shock or vibration and the life of incandescent lamps is significantly below the vehicle life. The lighting device conditions, especially when using complex optics, must therefore be designed so that the bulb can be replaced. Because when replacing the light bulb the lighting device in each Case must be opened, lighting equipment in the Are arranged outside the motor vehicle, special means for Sealing should be provided. In addition, requires a removable Lighting device paragraphs or columns in the surface of the Assemblies in which the lighting device is integrated, the Wind noise or vibration problems can lead.

The spatial expansion of the filament of incandescent lamps results in together with the large outlet aperture of the reflector to be used a large divergence angle when emitting light from the Lighting device. A large divergence angle makes this difficult Influencing the beam path and thus a conscious control of the Lighting characteristics, especially with regard to unwanted scattered light. The illuminated lighting fields can therefore only difficult by influencing the lighting characteristics of the opti paint requirements of the lighting task to be adjusted. A Optimization of the illuminance distribution is therefore mostly also impossible, since usually only an incandescent lamp is used as the light source becomes. Nevertheless, there are extreme demands on the design of the Be luminance distribution, complex and expensive opti such as special reflectors or asymmetrical, nested ones  Fresnel lens systems are used. The development and manufacturing such systems are time-consuming and expensive.

By using gas discharge lamps only the problems caused by the thermal losses of incandescent lamps defused. Gas discharge lamps require an even larger one for this Installation space and their lighting characteristics is even through that Can hardly be influenced by using special optics.

The object of the present invention is therefore to be a lighting direction to create the function of the well-known lighting can fully meet directions and thereby a low min minimum size, generates little waste heat, has a long service life has, which is above the life of the vehicle, and their lighting tion characteristics can be controlled well.

This task is accomplished by a lighting device with the characteristics len of claim 1 solved.

Particularly preferred embodiments are the subject of Subclaims.

In the proposed lighting device is used as a lamp at least one light emitting diode is used, which is essentially white light radiates. The use of light emitting diodes to fulfill lighting tion functions is known in principle. LEDs are relatively small, d. H. they generally have a diameter in the range from 0.5 to 10 mm and therefore require a relatively small minimum size high efficiency, produce little waste heat long service life, which is above the vehicle life. The Illumination characteristics of light-emitting diodes can be appropriate beam deflection devices and / or corresponding lens systems be well controlled.

A disadvantage of the previously known LEDs was that with them only monochromatic, i.e. monochrome light, with relative  low light intensity could be generated. This faint colored Light was used to perform most lighting tasks in motor vehicles stuff not usable. Through the further development of LEDs it has recently become possible to manufacture light-emitting diodes that emit white light emit with a relatively high light intensity and therefore the light bulb or Fluorescent tube as illuminant in lighting devices from Motor vehicles can substitute. These new types of LEDs are ready for the market and released for use in motor vehicles.

Basically, LEDs with any available Luminous intensity are used, the luminous intensity of the light emitting diodes and the number of LEDs to be used on the respective Be lighting task, especially on the distance to be illuminated Object to vote. The LEDs should usually have the smallest possible angle of radiation so that little stray light produce. LEDs are available with an integrated lens have and the radiation angle is in the range of 10-30 °.

The light color of the white light that can be generated by the light emitting diodes is due to the design and cannot be changed. If this light color for the fulfillment of a certain lighting task is optimally suitable, the lighting device should have at least one Have light emitting diode, the monochromatic, d. H. colored light emits. The monochromatic and white light of the different Light-emitting diodes mix on the lighting field, causing the light color by an appropriate mixture ratio optimally to the Erfor can be adapted.

In many cases, the light intensity of a light emitting diode is off Illumination of a sufficiently large lighting field with sufficient Luminous intensity not possible. In these cases, several LEDs must be used be summarized in the lighting device to the light add strength of the individual light emitting diodes on the lighting field.  

Due to the design, the individual LEDs must be in the lighting direction be arranged side by side. Because the LEDs are one light propagating substantially in a straight line along its beam axis generate cone, several LEDs on the Illumination field of adjacent lighting circles. So it can the size of the lighting by simply adding more LEDs tion field are increased, the increase in light intensity at one certain point of the lighting field is not possible.

Should the light emitted by the lighting device be at a or several specific points can be focused to illuminate The lighting characteristics can be changed in the lighting device tion at least two light emitting diodes with not parallel to each other beam axes can be arranged. The relative arrangement of the Light-emitting diodes should be chosen so that the light circles are on the loading lighting field according to the desired lighting characteristics overlap.

Although the arrangement of the LEDs in the lighting with different beam angles characteristics can be varied, but this is a complex LED or carrier body necessary for the correspondingly aligned Relative arrangement ensures. In particular the arrangement of light emitting diodes on a circuit board is then not possible because the LEDs are on Such a flat module all have the same beam axis profile have perpendicular to the board. In these cases, the lighting should characteristic can be influenced, so in the beam path of the individual light emitting diodes emitted light in front of the light emitting diodes Arranged lens system can be arranged that the light rays distracts according to the desired lighting characteristics. The Arrangement and design of the individual lenses in the lens system is to be matched to the desired lighting characteristics.

If a particularly differentiated lighting field is necessary, Both concepts can be used to influence the lighting characteristics  can be combined with each other. That is, the lighting device scatters on the one hand, the light through a lens system and individual light-emitting diodes have a specially aligned beam axis.

It is particularly inexpensive to manufacture the individual light diodes oden of a lighting device in a manner known per se on a Printed circuit board or foil (PCB's) to a light emitting diode module summarize. When using a printed circuit board, a two is Dimensional distribution of the LEDs when using Lei terfolien a three-dimensional distribution of the LEDs in the Be lighting device possible. Over the circuit board or foil the LEDs can be powered centrally and that The LED module can be used as a prefabricated assembly in one Housing can be mounted.

Basically, the electronics can be used to control the LEDs anywhere in the vehicle, also far away from the light diodes oden, for example, by integration into an on-board computer be. The electrical control circuits should be preferred the LEDs, that is, the necessary electrical components and electrical conductor tracks together with the light emitting diodes on one Printed circuit board or foil to a light emitting diode module be grasped. This integration reduces wiring and assembly expenditure. The flat assemblies can be inexpensively known per se Art to be mass-produced.

If the lighting device in the outer area of the motor vehicle measures must be taken to ensure that the contact of the Exclude the LED module with water. Penetrating moisture current can cause faulty currents and short circuits and thus lead to faults function and damage the electrical components. The The LED module should therefore preferably be water-protected forms to prevent the contact of penetrating moisture with the to prevent electrical components. Thanks to the water-protected version The corresponding areas of the light-emitting diode module can be used  elaborate watertight sealing of the entire housing is eliminated. Moisture protection can be particularly simple and inexpensive be sufficient if the LED module at least partially in poured a water-resistant material, such as a resin is. When designing the resin jacket, make sure that a sufficient heat dissipation from the light-emitting diode module is possible. The Light-emitting diodes themselves should not be cast in resin as this would excessive light losses would be caused. The unprotected areas of the light-emitting diode module, for example the side of a printed circuit board of which the LEDs are arranged are correspondingly different Protect sealing measures from moisture.

Since the lifespan of the LEDs is above the lifespan of the Motor vehicle is under normal circumstances, the exchange of LEDs are not required during the life of the motor vehicle such. Therefore, it is particularly cheap, the light emitting diode or that To permanently connect the LED module to the housing, because the permanent connection between light emitting diode or light emitting diode module and the housing can be particularly cost-effective, for example by gluing ben of the components, are manufactured and is particularly vibration and shockproof. If a light indicator falls during the life of the vehicle ode off, the entire housing must be in the case of one-piece housings multi-part housing the housing part, which with the light emitting diode or LED module is permanently connected, can be replaced. This increases the cost of changing the LEDs, but comes because of very high life expectancy of the LEDs very rarely.

In principle, it is sufficient if the LEDs on the outside the housing of the lighting device are arranged and that generated light are emitted onto the desired lighting field can. In this case, however, the LEDs are all external influences sen, especially mechanical damage and weather influences sen, exposed. To protect the LEDs from these influences, it is advantageous if in the housing in the beam path of the light emitting diodes  a transparent cover plate is arranged in the housing. With in other words, the LEDs between the cover plate and Enclosed housing. Due to the transparent material of the Plate can pass through the generated light unhindered and unfavorable Mechanical and weather influences are caused by the LEDs held. The plate should therefore have sufficient mechanical Have strength and be as watertight as possible with the housing be that.

If the lighting characteristics of the lighting device by the Arrangement of a lens system in front of the light-emitting diodes are influenced, this can be realized particularly cost-effectively if the necessary lenses in the transparent cover plate in front of the LEDs are incorporated. This can be done by appropriate grinding Cover plate or through the arrangement of lens-like material thickening in the cover plate. It is particularly cheap, each areas opposite a light-emitting diode on that of the light-emitting diodes to form the facing side of the cover plate as lenses. So that can the beam path of the individual light-emitting diodes can be specifically controlled because a lens is provided for each light-emitting diode with which the light beam can be deflected, and the smooth outside of the cover plate can connected to the outside of the housing essentially without gaps so that no dirt can get caught in the transition area and there are no unwanted wind noises. They are also Lenses on the inside of the cover plate from harmful mechanical Influences protected.

The cover plate can be made from any transparent material be made of glass. However, glass has the disadvantage that it is relatively brittle and therefore breaks easily and the attachment of Lenses in the glass, for example by an appropriate cut, is relatively expensive. The cover plate should therefore be preferred a transparent plastic. Plastic is light, has a sufficiently high mechanical strength and is above  weatherproof. A cost advantage results from the fact that required lens system very easily by appropriate modification the shape of the plastic cover plate can be made. To just have lenticular bumps on one or both sides the cover plate are provided. The negative form of this lenticular For this purpose, elevations only have to be incorporated into an injection mold become. This increases tool costs by a small amount Amount, the actual manufacturing costs for a cover plate However, plastic lenses are no higher than for a cover plate without lens.

When designing the lenses, it is advantageous to provide smooth lenses, d. H. Lenses with a smooth lens surface. Lentils are also included Surface structure, for example Fresnel lenses, conceivable, but ver the surface structure reduces the luminous efficacy of the lighting direction.

The cover plate is in the housing in the area above the light di oden inserted and fastened. The cover must fit securely plate can be guaranteed so that even after a long time space is not lost. In addition, the LEDs according to Mög be protected from moisture and dirt, which is why the Gap between cover plate and housing closed as tightly as possible should be. This can be achieved, for example, in that the Cover plate is glued into the housing.

It is more cost-effective if the cover plate and the housing are common sam be produced in a multi-component injection molding process. The housing is made of simple plastic and the cover plate made of transparent plastic at the same time in a common spray mold made. The transparent plastic of the cover plate detects itself in an interface with the plastic of the housing, so that the cover plate becomes an integral part of the housing. At In this design, the LEDs are safe from moisture and  Dirt protected because of a material bond between the cover plate and the housing consists.

Of course it is also possible if, for example, the two Plastics for cover plate and housing are not compatible with each other are and therefore not processed together in an injection mold be able to manufacture the two components separately and by one To connect clips or the like together.

Because the properties of light emitting diodes, especially the current carrying capacity speed and the emitted light intensity is temperature-dependent, the Power supply to the LEDs in a manner known per se via a non-linear resistor network or pulse width modulation direction. In particular by pulse width modulation of the Current can be the necessary temperature compensation of the current Simply implement the characteristic curve and also a smooth on or off switching of the LEDs to increase comfort.

As there are fluctuations in the operation of the vehicle electrical system voltage, which can damage the LEDs, should Measures to protect the LEDs from overvoltages become. For example, at least one protective diode should be in series with the LEDs are connected to protect them against reverse polarity. Of course, other protective measures are also conceivable, however Protective diodes enable particularly small peak reverse voltages.

Since LEDs also generate a certain amount of waste heat, the Temperature in the lighting device, especially in the case of permanent use driven the lighting device, rise to an impermissibly high level. To one Damage to the components due to excessive temperature stress to be able to conclude, it is advantageous to adjust the temperature in or on the Monitor lighting device with a temperature sensor. The The output signal of this temperature sensor can then be sent to the controller Power supply to the light emitting diode and the current supply depending on the measured by a temperature sensor  whose temperature can be controlled in the lighting device. The control can either be limited to over If a reference temperature is exceeded, the power supply is switched off or withdraw the power supply proportional to the temperature.

Of course, it is possible to use a lighting device proposed type as a separate assembly, d. H. with your own Housing, to design and to fix in or on the vehicle. However, it is optically more appealing and more cost-effective than the housing To design part of an existing assembly. In other words this means that the lighting device is in a different assembly is integrated and so a multi-function module with common Housing is created.

In principle, many assemblies of a motor vehicle are conceivable in the a lighting device of the proposed type meaningfully integrated could be. Bumpers, sliders are particularly worth mentioning roof control modules, trunk covers, engine compartment covers, Glove compartments, ashtrays, car keys, storage compartments, with tele consoles, seats and the like. This is all the more true since in many of these Assemblies due to the lack of installation space or insufficient Waste heat dissipation no lighting devices are integrated could.

It is particularly favorable if the housing of the lighting device is formed as part of an interior rear-view mirror, whereby the lighting device becomes an integral part of the interior rear-view mirror. By positioning the interior rear view mirror in the upper area of the Passenger compartment, the lighting device in particular as a reading light and / or for interior lighting. Because the LEDs need only a small installation space and give off little waste heat the inner rear view mirror in its outer slim form essentially cannot be changed. A redesign can therefore largely omitted. Will a lighting device according to the invention inside arranged space of the vehicle, this can, with appropriate vote  the lighting characteristics, even while driving continue to burn, and thus selectively and with low glare while driving Subareas of the vehicle interior, e.g. B. the gear stick or Storage areas, illuminate.

It is also advantageous if the housing of the lighting device is part a decorative molding. Such moldings with integrated loading lighting device can then in the door area of the motor vehicle be arranged and the street area below the doors during illuminate the boarding process. The realization of a lighting device in the trim with one or more light bulbs, because of the required installation space and the large amounts of waste heat, not possible. A narrow elongated board with a large number on it arranged light emitting diodes, however, can be very well into the narrow Integrate the structure of a molding.

Because of their body geometry also very suitable for integration for a linear arrangement of LEDs, the door handles are Vehicle. The handles on the driver's, Passenger and rear side. The lighting integrated in the door handles device can either be used to illuminate the surrounding area of the respective door and / or as an orientation aid making it easier for vehicle users to find the door handles, to serve.

The same purpose of illuminating the entrance area in front of the Doors serve lighting devices in the exterior rear view mirror are integrated. A preferred design is therefore the Ge housing of the lighting device as part of an exterior rearview mirror to train. The small design of the individual LEDs allows they are optimal for fulfilling the lighting task in the exterior rearview position gel. This means that the light emitting diodes can be very far out be placed near the outer end of the exterior rearview mirror what is not possible for lighting devices with incandescent lamps, because in little space is available in this area of the exterior rear-view mirror  stands. The placement of the lighting device at the outer end of the Exterior rear-view mirror also enables the part of the car to be illuminated Entry area that is already below the vehicle floor.

Since the proposed lighting device is not of all purchase interests Essenten of a vehicle type desired at a correspondingly higher price be, it is conceivable to only one part of the delivered vehicles Type with such lighting devices as optional equipment Mistake. If the lighting device is not used in all vehicles Type, but only depending on the customer's wishes as a special equipment installed, the lighting device should be removed barer part of a vehicle assembly, in particular as a cover ring or Cover cap of an exterior rearview mirror can be formed. This could all vehicles of the same type with basically the same vehicle assembly, such as an exterior rearview mirror and the modification regarding the special equipment would have to be ordered replacement of the removable part of this vehicle construction group, for example the cover ring or the cover cap Exterior rear-view mirror, possible. This measure would allow the parts reduce diversity in the assembly of the motor vehicle and thus reduce associated costs.

In the following, the lighting device is only used before Drawn embodiments of drawings showing explained. It shows:

Figure 1 shows the lower part of an exterior rear view mirror with integrated LED lighting device in cross section.

Fig. 2 is a motor vehicle from behind to illustrate various uses of LED lighting devices.

1 Fig. 1 shows a wing mirror of a motor vehicle with a mirror element 2, a support plate 3 and a housing 4. For better visibility, only the lower part of the housing 4 facing the rear of the vehicle is shown. The electric drive and the adjustment gear for adjusting the support plate 3 in the housing 4 are not shown.

In the lower component wall of the housing 4 , an illuminating device 5 is integrated. The housing 4 of the exterior rearview mirror 1 thus simultaneously forms the housing for the lighting device 5 . The lighting device 5 has a light-emitting diode module 6 with the circuit board 8 and a cover plate 7 .

In the light emitting diode module 6 8 light emitting diodes 9 are on one side of the circuit board, which emit white light with a beam angle of ± 15 °, and on the other side of the circuit board 8 electrical construction parts 10 for controlling the light emitting diodes 9 are integrated. The electrical components 10 on the back of the circuit board 8 are surrounded by a resin jacket 11 and are thus protected from moisture. The light-emitting diode module 6 is electrically connected via a plug 12 . The light-emitting diodes 9 are each surrounded by an open, tube-like tube 26 , which reduces the scattered light emitted and ensures an essentially vertically downward beam path.

In the component wall of the housing 4 , the two webs 13 and 14 projecting inwards into the housing are integrated, to which the light-emitting diode module 6 can be attached. For this purpose, the webs 13 and 14 have a clip contour that is form-complementary to the outer contour of the printed circuit board 8 . When mounting the light emitting diode module 6 into the housing 4 in the contact area of a sticky sealant 15 is applied, which connects the light emitting diode module 6 unreleasably to the housing 4 and the area 16 on the lower side of the Leuchtdiodenmo duls 6 airtight with respect to the region 17 in the Encloses housing 4 above the LED module 6 .

The cover plate 7 is made of transparent plastic. Cover plate 7 and housing 4 are produced in a two-component injection molding process, which is why a flowing material transition between the housing 4 and the cover plate 7 is created. The sharp part boundaries shown in FIG. 1 between the housing 4 and the cover plate 7 only serve to make them more easily recognizable and do not reflect the actual boundaries that are blurred. This integral manufacture of cover plate 7 and housing 4 creates an airtight connection between these two components. As a result, the cohesive connection between the housing ( 4 ) and cover plate ( 7 ) and the airtight gluing of the light-emitting diode module 6 into the closed circumferential webs 13 and 14 form an airtight encapsulated chamber in the area 16 between the printed circuit board 8 and the cover plate 7 . The light-emitting diodes 9 are reliably protected from moisture and dirt in this airtight chamber in the area 16 .

On the inside of the cover plate 7 , the lenses 18 are integrated into the cover plate 7 in each case opposite the light emitting diodes 9 . To produce these lenses, lens-shaped depressions were incorporated in the injection mold, so that 7 linsenför shaped material increases are formed on the transparent cover plate, which act as converging lenses. If necessary, diffusing lenses can also be realized by forming appropriate material recesses in the cover plate 7 . The lenses are arranged on the upper side of the cover plate 7 and are therefore also located in the protected encapsulated area 16 .

The lenses 18 serve to influence the beam path 19 of the light that is emitted by the individual light-emitting diodes 9 . The light emitting diodes 9 on the printed circuit board 8 all have the same beam angle, which is why a lens system must be arranged in front of the light emitting diodes 9 in order to control the lighting characteristics of the lighting device 5 . The lenses 18 make it possible to deflect the light emitted by the individual light-emitting diodes 9 , each with a parallel beam axis, and thereby to concentrate them in the region A of the illumination field 20 . The lighting characteristics of the lighting device 5 can thus be influenced in a targeted manner.

Between two of the LEDs 9 , the temperature sensor 27 is net angeord. The temperature sensor 27 monitors the temperature in the area between the printed circuit board 8 and the cover plate 7 . If the temperature in this area rises above a reference temperature, the temperature sensor 27 outputs a corresponding signal and the electrical control of the light-emitting diode module 6 interrupts the power supply to the light-emitting diodes. Only when the temperature has dropped sufficiently will the power supply be opened again. An inadmissible thermal load on the components is excluded by the temperature sensor 27 and the corresponding control.

Fig. 2 shows a motor vehicle in rear view. In an interior rearview mirror 21 , the two exterior rearview mirrors 22 and 23 and the decorative strips 24 and 25 , which are arranged in the door area of the motor vehicle, lighting devices according to the invention are integrated in each case. The lighting device in the interior rear-view mirror 21 can be used as interior lighting or reading lights. The lighting devices in the exterior rear-view mirrors 22 and 23 and the trim strips 24 and 25 serve to illuminate the entry area of the motor vehicle in order to increase the safety and comfort of the vehicle users.
