Description

[0001] The invention relates to a lighting device according to the preamble of claim 1.

[0002] Such a lighting device is described in DE 10 2006 046 438 A1. Specifically, this document describes a motor vehicle headlight comprising three headlight sub-units. Two of the headlight sub-units operate on the reflection principle and feature LEDs mounted on a heat sink, the light beams of which can be directed via a reflector in the direction of the headlight's emission. A third headlight sub-unit is based on the projection principle and also features an LED mounted on a heat sink, the light beams of which can be directed via a focusing optic and a lens in the direction of the headlight's emission. The headlight can provide either low beam or high beam illumination.

[0003] From DE 198 60 461 A1, a headlight for vehicles with multiple headlight units for generating light beams with different characteristics is known. One of the headlight units is designed such that it can alternately generate a light beam with a low beam characteristic or a light beam with a high beam characteristic. The headlight unit can be constructed according to the reflection principle or the projection principle.

[0004] German patent DE 10 2008 036 194 A1 describes a light module for a motor vehicle lighting system. The light module comprises a heat sink to which two hemispherical reflectors are attached laterally opposite each other, each with an LED mounted on the heat sink. A shutter assembly is arranged in the direction of light emission from the reflectors and can be moved in and out of a generated beam path. A projection lens located downstream in the direction of light emission generates the light distribution for either low beam or high beam, depending on the position of the shutter assembly.

[0005] German patent DE 103 40 433 A1 describes a vehicle headlight with eleven lighting units of different types. Some units are projector type, others are direct projection type, and still others are reflection type.

[0006] Finally, a lighting device is also known from DE 10 2007 008 403 A1. Specifically, a lighting device with several reflector chambers is described therein, with each reflector chamber having an LED as its light source. The light reflected by the LEDs from the reflectors forms an individual light distribution and can be used, either on its own or in combination with the other individual light distributions, as needed to create a (total) light distribution for specific lighting functions, such as low beam, high beam, fog lights, cornering lights, and the like.

[0007] The individual reflector chambers can be arranged and combined in any way. This should result not only in a shallow installation depth and good adaptability to the installation space, but also in new design possibilities for both day and night applications.

[0008] The text indicates that modern lighting devices are subject to high demands regarding both their functionality and their individualizability (day and night design).

[0009] The present invention is based on the objective of providing a lighting device that, in addition to high functionality, also breaks new ground in terms of appearance.

[0010] This problem is solved by the features of claim 1. Advantageous embodiments of the invention can be found in the dependent claims.

[0011] The invention relates to a lighting device, in particular a headlight, for a motor vehicle for generating one or more specific lighting functions, with at least two light sources by which light rays attributable to at least one lighting function can be generated or are generated, wherein the generated or generated light rays are deflected or deflectable by at least one of the light sources via at least one reflector and can be supplemented or complemented with the generated or generated light rays of at least one other light source to form an overall light distribution.

[0012] Furthermore, it is proposed that at least one of the light sources be designed as a light module having a lens.

[0013] The present lighting device combines or superimposes the reflection principle with the projection principle. This allows for the reliable generation of individual light distributions, which can also be combined into a complete light distribution as needed. At the same time, this innovative design gives the lighting device a distinctive appearance.

[0014] According to a first advantageous embodiment of the invention, it is provided that the light rays deflected via the reflector are generated by at least one semiconductor light source, preferably by at least one light-emitting diode (LED).

[0015] At least one LED can be part of a single-chip or multi-chip LED module. In a single-chip module, one LED is mounted on a single chip or circuit board. The basic building block of a multi-chip LED module consists of individual LEDs connected in a matrix and mounted on a circuit board, such as a ceramic plate. The advantage of multi-chip LEDs, compared to large-area single-chip LEDs with nearly the same luminous flux, lies in their homogeneous heat distribution. While the generated heat must be dissipated from a single point, or a very small area, the lower temperatures resulting from low currents in multi-chip LEDs can be distributed and dissipated over a larger area. This significantly simplifies thermal management.

[0016] The use of LEDs in conjunction with the reflection principle allows for a more compact design of the lighting device compared to the use of other, even conceivable, light sources.

[0017] It is very advantageous to position the light module in front of the reflector. This allows for a special depth effect in the appearance of the lighting device, both in day and night designs.

[0018] A further embodiment of the invention provides that the light module is assigned the function of a low beam and the reflector the function of a high beam. This makes the low beam stand out as a point from the high beam, which also contributes to a distinctive appearance.

[0019] But another, for example reverse, assignment is also conceivable.

[0020] At least two reflectors can be provided, whereby the light module can be assigned a first light function and each of the reflectors can be assigned a further light function.

[0021] This allows the functionality of the lighting system to be further enhanced. For example, the light module can be assigned the function of a low beam, the first reflector the function of a high beam, and the second reflector the function of an auxiliary high beam, a cornering light, a motorway light, a city light, or the like. Adding further reflectors with corresponding additional lighting functions is also conceivable. It is also possible for several reflectors to be assigned a common lighting function.

[0022] The reflectors can be joined together as a single piece or exist as separate components.

[0023] It has proven advantageous to arrange two reflectors side by side or one above the other and to hold the light module by at least one component located between the reflectors. This allows for good "optical" separation between the lighting functions.

[0024] The component can be designed as a carrier for LEDs whose light beams can be emitted directly in the main direction of light emission—that is, in the direction of travel for headlights and against the direction of travel for taillights—and assigned to an additional lighting function. This can also contribute to increased functionality. For example, the light beams of the LEDs can be assigned to the daytime running light function.

[0025] A further increase in functionality and also a variation in appearance can be achieved if, according to features of the invention, the lighting device is covered with a light disc to which at least one support for holding LEDs is attached.

[0026] The LEDs held on the carrier can then be used, for example, to generate (additional) daytime running lights and / or to generate the light function of a direction indicator.

[0027] The invention also relates to a motor vehicle with at least one lighting device according to the invention, the lighting of which can be improved by a lighting device according to the invention.

[0028] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description. Reference numerals refer to identical, comparable, or functionally equivalent components.

[0030] First, let's talk about the Fig. Reference is made to points 1 to 3.

[0031] The figure shows a motor vehicle K, which is equipped with two lighting devices 1 according to the invention. The lighting devices 1 are designed as headlights.

[0032] This is in Fig. Figure 2 shows a front view, with only the left headlight 1 shown in some detail. In this illustration, it can be seen that the lighting devices 1 are located laterally adjacent to a radiator grille, which has grille louvers 3. A bumper 2 is provided below the radiator grille and the lighting device 1.

[0033] As from Fig. As can be seen in particular in Figure 3, the lighting device 1 has a housing 10 which serves to accommodate reflectors 100, 101 (indicated by dashed lines), to accommodate a light module 34 comprising a lens for realizing the light function of a low beam, and to accommodate several light-emitting diodes (LEDs) 50 for realizing the light function of a daytime running light.

[0034] The light module 34 is held on a specially designed base plate 33, which in turn is attached to the housing 10 and also serves as a carrier for the LEDs 50 and other light sources. The base plate 33 is used particularly in the Fig. 13 and Fig. 14 described.

[0035] Furthermore, the housing 10 is covered by a lens 20, which is connected to the housing 10, for example by gluing or welding. After the lens 20 is attached to the housing 10, it can be assigned an outer surface A and an inner surface I.

[0036] It can be seen that two elongated, lamellar or wing-like components 40 and 41 are connected to the light disc 20 below the base plate 33. The lamellar components 40 and 41 serve as carriers for light-emitting diodes (LEDs) 51 and 52, respectively.

[0037] Furthermore, it is evident that components 40 and 41 are arranged visually as a continuation of the radiator grille louvers 3. Components 40 and 41 protrude from the outer surface A of the lens 20.

[0038] In the lighting device 1, the LEDs 50 are assigned the light function of a daytime running light, the LEDs 51 the light function of a direction indicator and the LEDs 52 also the light function of a daytime running light.

[0039] In Fig. Figure 4 shows a lighting device 1'.

[0040] A slightly differently designed light lens 20' is provided here. A component 42, which serves as a carrier for LEDs 51 and 52, is connected to the light lens 20'. The LEDs 51 and 52 also serve to implement the lighting function of a turn signal or daytime running light.

[0041] In contrast to the embodiment according to Fig. 3 the component 42 extends inwards to the inside I of the lighting device 1'.

[0042] The fastening of the in the Fig. 3 and Fig. The connection of the four components shown (40, 41 and 42) can be done in a variety of ways. For example, screwing, gluing, snapping or similar methods are possible.

[0043] In Fig. Figure 5 shows that the component 40 is connected to the light disc 20 via a screw bolt 27 which is cast into the light disc 20.

[0044] Fig. Figure 6 shows an alternative fastening option in which the component 40 is connected to the light lens 20 via a snap-fit ​​connection 28.

[0045] Fig. Figure 7 describes another variant of a light disc 20''', which is provided with a pre-assembled unit comprising an injection-molded, lamellar carrier 200 for an LED 51 and a holder 205. The carrier 200 and the light disc 20''' are thus integrally connected. The carrier 205 with the LEDs 51, or the circuit board associated with the LEDs 51, is inserted into a cavity 201 of the carrier 200 and thereby held in place.

[0046] Furthermore, it is evident that a cover part 202 is applied to the carrier 200, and in particular connected to it via a snap-fit ​​connection 203. The cover part 202 can be opaque, i.e., light-blocking, and provided with a front opening 204, so that the light emitted by the LEDs 51 only escapes through the opening 204.

[0047] With the light lens 20''' remaining unchanged, the cover part 202 can be designed differently, for example with regard to the design of translucent or opaque areas, the design of the openings 204, etc.

[0048] In Fig. Figure 8 shows a variant of a light disc 20'', wherein the light disc 20'' is designed such that it can serve for the direct mounting of LEDs 51. Specifically, the light disc 20'' has contact surfaces 206 to which the LEDs 51 can, for example, be glued.

[0049] Now referring to Fig. Figure 9 shows the lighting device 1 according to the invention in isolation and in even more detail.

[0050] The lighting device 1, designed as a headlight, comprises two identically constructed holders 30 for light sources, each of which is assigned a wide variety of lighting functions, some of which differ from one another (see also Fig. 12, Fig. 13, Fig. 15 and Fig. 19). The one in the Fig. 9 The right (outer) bracket 30 is slightly smaller than the left (inner) bracket 30.

[0051] The brackets 30, in particular their base plates 33, are connected to the housing 10 via a receptacle 103 (see also Fig. 12) connected and arranged in front of reflectors 100, 101 and a side wall 102 surrounding them. The housing 10 is covered by the light lens 20 (see arrow), the light lens 20 having a transparent (translucent) wall section 21 and an opaque (light-blocking), in particular black, wall section 22 located below it. The black wall section 22 is provided with two slot-like through-openings 23 and 24, which are arranged one above the other and serve to receive the lamellar components 40 and 41 (see dashed line). As already mentioned, the components 40 and 41 serve as carriers for a plurality of LEDs 51 and 52, respectively, with the upper part 40 acting as a direction indicator and the lower part 41 as a daytime running light.

[0052] Components 40 and 41 can be accessed, for example, from the inside I (see below). Fig. 3) inserted through the through-openings 23 and 24 and secured with flanges (indicated by dashed lines in Fig. 17) be screwed or glued to the lens 20.

[0053] In the Fig. 10 and Fig. Figure 11 now shows the light disc 20 in isolation. This is particularly evident from the Fig. Figure 11 shows that the transparent area or wall section 21 of the light disk 20 and the black area or wall section 22 are connected to each other via an area or wall section 26 that projects approximately horizontally or in the direction of light emission. Above the transparent wall section 21, there is another black wall section 220.

[0054] Behind the transparent wall section 21, the supports 30 are arranged. Furthermore, it is clearly visible that the wall section 26 is provided with semicircular recesses 25.

[0055] The recesses 25 are designed to be translucent and serve to receive the front part of the bracket 30 or its base plate 33, which is equipped there with the LEDs 50 to implement a daytime running light (see also Fig. 12 and Fig. 13).

[0056] Based on Fig. In section 12, the bracket 30 will now be described in more detail.

[0057] As already mentioned, the bracket 30 is positioned in front of the reflectors 100, 101 and the side wall 102. The reflectors 100 and 101 are arranged vertically one above the other and separated from each other by means of a receptacle 103 into which the rear part of the base plate 33 is inserted (see dashed line).

[0058] The holder 30 serves to hold various light sources to create different lighting functions, as shown by the Fig. 13 and Fig. 15 and 19 are described in more detail.

[0059] Firstly, the bracket 30 serves to hold the light module 34. The light module 34, which can also be referred to as a projection module, has a lens (projection lens) 340, a collimator 341 arranged behind it, and a heat sink 342 arranged behind the collimator 341. Furthermore, LEDs for generating light beams for the light module 34 are also incorporated in the light module 34 (not shown). In the exemplary embodiment, the light module 34 is assigned the function of a low beam. The reflectors 100 and 101 arranged behind the bracket 30 are each assigned the function of a high beam and a so-called auxiliary high beam, respectively (see also...). Fig. 15 and Fig. 19).

[0060] The light module 34 is positioned between two supports 32, which carry a cap-like cover 31 and are connected to the aforementioned base plate 33.

[0061] In the front area of ​​the base plate 33 a light guide 336 is provided, which is arranged in front of the LEDs 50.

[0062] In Fig. 13. The base plate 33 of the bracket 30 will now be described in detail.

[0063] The base plate 33 consists of an upper part 320 and a lower part 330. The upper part 320 is flat and consists (as does the lower part 330) of a material with good thermal conductivity, for example aluminum.

[0064] The upper part 320 can be divided into a front part 321 and a rear part 322, with the front part 321 being narrower than the rear part 322 in terms of the surface area of ​​the base plate 33, comprising approximately one-third of the latter's width. The front part 321 and the rear part 322 merge seamlessly into one another and are provided with a ribbed surface 323. This ribbed surface 323 effectively increases the heat-radiating surface area and also creates an attractive design.

[0065] In the area of ​​the front part 321, an elongated hole 324 is provided.

[0066] In Fig. Figure 14 shows the underside of the upper part 320 of the base plate 33. It can be seen that it has a support surface 326 in the area of ​​the rear part 322. The upper part 320 can be placed on a support surface 333 of the lower part 330 of the base plate 33 using this support surface 326, and thus be fastened to it.

[0067] Furthermore, 320 rectangular recesses 325 are visible on the underside of the upper part, in each of which an LED chip 60 is adjustably attached.

[0068] One of the LED chips 60 is positioned so that it illuminates the reflector 100 with light rays, while the other LED chip 60 is oriented so that it illuminates the reflector 101 with light rays (see also Fig. 15).

[0069] Alternatively or additionally, it is conceivable to design the reflectors 100,101 to be adjustable / swivelable relative to the base plate 33 (not shown in detail), so that they too can be aligned as required.

[0070] The 60 LED chips can be switched or activated individually or together to create a desired light distribution of a high beam.

[0071] The lower part 330 can also be subdivided into a front part 331 and a rear part 332. The widths of parts 331 and 332 are adapted to the widths of parts 321 and 322.

[0072] In contrast to the rear part 322 of the upper part 320, the rear part 332 of the lower part 330 is not formed over a full surface, but widens (starting from the front part 331) towards the rear in a forked shape to two ends, between which a light space is created.

[0073] Furthermore, a recess 334 extending from the front is provided in the front part 331, which is equipped with three holders 335 for LEDs 50. The recess 334 is covered with the aforementioned light guide 336.

[0074] Following the front recess 334, a groove 337 is provided in the longitudinal direction of the lower part 330. This groove 337 serves for the slidable and adjustable mounting of a slide 70, which in turn serves to mount the lens 340 to the light module 34. The slide 70 can project through the elongated hole 324 of the upper part 320, with the elongated hole 324 providing sufficient space for longitudinal movement of the slide 70. The guide formed by the slide 70 and the groove 337 can be designed as a so-called dovetail guide.

[0075] The adjustability of the lens 340 achieved in this way allows its distance to the collimator 341 to be easily adjusted.

[0076] The sled 70 serves simultaneously as a holder for electrical components and as a cable distributor (not shown).

[0077] In Fig. Figure 15 shows, in principle, the arrangement formed from the holder 30, the light module 34 held on it and the reflectors 100 and 101.

[0078] The arrangement, in particular the design of the base plate 33 of the holder 30, enables a very compact design of the lighting device 1 according to the invention despite a large number of realized lighting functions.

[0079] It is indicated in principle that the LED chips 33 attached to the base plate 60 project light beams L1 onto the upper reflector 100 and light beams L2 onto the lower reflector 101. The light beams L1 and L2 are reflected forward in the direction of travel by the reflectors 100 and 101.

[0080] Furthermore, the light module 34, which is attached to the base plate 33 and thus arranged in front of the reflectors 100,101, generates light rays L3 and also throws them forward in the direction of travel.

[0081] Finally, the 50 LEDs attached to the front of the base plate also project light beams L4 forward in the direction of travel.

[0082] By selectively activating the light sources arranged on the base plate 33, which can also be activated together in any combination, a desired overall light distribution L can be flexibly produced.

[0083] Additionally or alternatively, the light sources 51 and 52 connected to the light disc 20 via components 40 and 41 can be activated (see Fig. 9).

[0084] In Fig. In section 19, the arrangement of the reflectors 100 and 101 and the holder 30 together with the light module 34 of the lighting device 1 is discussed once again in a very fundamental way, whereby the two identical units of a lighting device 1 consisting of reflectors 100, 101 and holders 30 are indicated.

[0085] It can be seen that within the lighting device 1, two units consisting of reflectors 100, 101 and holders 30 are arranged side by side. Two reflectors 100 are arranged side by side in a row, and two reflectors 101 are arranged side by side in a row below. Each of the upper reflectors 100 is assigned a high beam function LF1, and each of the lower reflectors 101 is assigned an auxiliary high beam function LF1'.

[0086] The auxiliary high beam function LF1' can either supplement the high beam function LF1, for example by providing an even wider illumination of the road, or replace it entirely. This depends on the control of the LED chips 60. However, instead of the auxiliary high beam function LF1', other lighting functions assignable to the reflectors 101, such as fog lights, cornering lights, city lights, or the like, are also conceivable.

[0087] In the illustrated view, each unit has a holder 30 positioned vertically between reflectors 100 and 101. This holder compactly supports the light sources for the high beam function LF1, the auxiliary high beam function LF1', a low beam function LF2, and at least part of a daytime running light function LF3. Thus, the high beam LF1 and auxiliary high beam LF1' functions are optically separated vertically by the low beam LF2.

[0088] Another part of the daytime running light function LF3 is, as already mentioned, realized by the LEDs 52 of the component 41 integrated in the light lens 20.

[0089] Especially from the Fig. 15 and Fig. Figure 19 makes it clear that in the lighting device 1, the light functions or light rays of different types of optical elements are "networked" with each other. In particular, the reflection principle (reflectors 100, 101) is combined or superimposed with the projection principle (projection module or light module 34).

[0090] In this way, the light rays L1 and L2 indirectly emitted by the reflectors 100 and 101 respectively can be superimposed by the light rays L3 emitted directly by the projection or light module 34.

[0091] The in Fig. The 15 reflectors 100, 101 of a unit shown in the figure can also be arranged offset from each other. For example, it is conceivable that the reflector 101 assigned to the auxiliary high beam LF1' can be offset forward in the direction of light emission relative to the reflector 100, i.e., to the left in the figure.

[0092] In contrast to the embodiment shown, it is also conceivable to assign only one light function to each of the reflectors 100, 101 and the light module 34 of a unit, e.g. the low beam LF2 to the outer unit and the high beam LF1, LF1' to the inner unit.

[0093] Finally, the aim is to use the Fig. Sections 16 to 18 will discuss in more detail the structure of component 40, which is essentially the same as that of component 41.

[0094] This is how it becomes Fig. 16 the lamellar or wing-like structure of component 40 is particularly evident.

[0095] In the outer edge area of ​​component 40, a large number of light-emitting diodes (LEDs) 51 are arranged.

[0096] Component 40 has a cavity 400, which serves to hold a holder 402 for the LEDs 51. A cover 403 made of Plexiglas is attached to the holder 402. The cover 403 has a tapered end section formed by a slot-like opening 401 in component 40.

[0097] Since component 40 is intended to implement the light function of a direction indicator, the LEDs 51 can be yellow. However, it is also conceivable to color the cover 403 accordingly.

[0098] As already mentioned, component 40 is inserted through the slot-like opening 24 of the light lens 20 (compare Fig. 9) pushed through from the back of the light disc 20 and attached to its back by means of flanges 406 indicated by dashed lines.

[0099] Alternatively, a component 40' is conceivable which, instead of a front, slit-like opening, has only a correspondingly geometrically designed, translucent area 405, which is limited above and below by opaque (non-translucent) areas 404.

[0100] Accordingly, a slightly different embodiment 402' could also be provided for a holder of the LEDs 51 (without an additional cover 403), wherein the holder 402' can again be inserted and held in a recess 400 of the component 40'.

[0101] The LEDs 51 can be attached to the holder 402 as individual LED boards or in the form of so-called flexboards (several LEDs on a flexible strip).
