Description

Technical Field

[0001] This invention relates to a lighting device for motor vehicles. Background Technology

[0002] As is known from existing technology, in addition to the main light functions (i.e., low beam and high beam), motor vehicle headlights also integrate other light functions, such as daytime running lights, position lights, or driving direction indicators. The light-emitting units with the corresponding light functions are usually arranged behind the light-transmitting outer lamp panel, through which the light of the light function is emitted from the headlight.

[0003] Especially in structures where the exterior light panel ends flush with the bumper trim of the vehicle, during a low-speed collision, it is necessary to prevent the deformation or movement of the exterior light panel caused by this from moving or damaging the light-emitting units inside the lighting device. Summary of the Invention

[0004] The objective of this invention is to provide a lighting device for motor vehicles, wherein the risk of damage to the light-emitting unit installed in the lighting device is kept small in the event of a low-speed collision.

[0005] The lighting device according to the invention is provided for motor vehicles, such as passenger cars and, if necessary, also for trucks. As the interaction between the lighting device and components of the motor vehicle is described below, it is always understood that this interaction occurs when the lighting device is arranged or installed in the motor vehicle. Therefore, components of the lighting device that have corresponding interactions with the motor vehicle, or more precisely, its components, are designed such that such interactions occur when the lighting device is arranged or installed in the motor vehicle.

[0006] The lighting device according to the invention includes one or more first light-emitting units, which are respectively configured to generate light distribution for low beam and / or high beam functions. In one variation, only a single first light-emitting unit is installed in the lighting device; however, it is also possible that multiple such light-emitting units are present to achieve either low beam or high beam functions. Preferably, the first light-emitting unit (as long as only one exists) or all of the first light-emitting units are configured to generate both low beam and high beam functions. Based on the low beam or high beam functions, the lighting device according to the invention is a lighting device for the front of a corresponding motor vehicle.

[0007] In addition to the one or more first light-emitting units, the lighting device according to the invention also includes one or more second light-emitting units, which are respectively configured to generate a light distribution for a light function different from the low beam and high beam functions. Preferably, at least a portion of the second light-emitting units and, if necessary, all of the second light-emitting units are configured to generate a light distribution for a signal light function.

[0008] The first light-emitting unit or the plurality of first light-emitting units and the second light-emitting unit or the plurality of second light-emitting units are covered by a common, at least partially light-transmitting, outer lamp panel through which light originating from the first light-emitting unit or the plurality of first light-emitting units and the second light-emitting unit or the plurality of second light-emitting units is emitted from the lighting device. Herein and hereinafter, the term "light" refers to optical radiation in the wavelength range visible to the human eye. Furthermore, herein and hereinafter, the term "transmittance" can be understood as having a transmittance greater than zero, and particularly 50% or higher, and preferably 90% or higher, for light.

[0009] In the lighting device according to the invention, the one or more first light-emitting units are arranged spaced apart from the outer lamp panel. Furthermore, the one or more second light-emitting units are respectively (mechanically) rigidly connected to or spaced apart from the outer lamp panel. Here, if necessary, some of the second light-emitting units may be rigidly connected to the outer lamp panel, while others are spaced apart. Preferably, at least some of the second light-emitting units rigidly connected to the outer lamp panel, and if necessary, all of these second light-emitting units are not only rigidly connected but also directly (i.e., without additional bridging components) connected to the outer lamp panel. The rigid (mechanical) connection can vary depending on the design. In particular, it can involve material-locking and / or force-locking and / or form-locking connections.

[0010] The lighting device according to the invention has the advantage that damage to the one or more first light-emitting units is avoided in the event of a low-speed collision (e.g., a parking collision) by the spacing between the first light-emitting unit and the outer lamp panel. In contrast, damage to the one or more second light-emitting units is resisted in such a collision by means that the second light-emitting units move together with the outer lamp panel due to their rigid connection, or by the second light-emitting units being arranged spaced apart from the outer lamp panel. Furthermore, the rigid connection between the second light-emitting units and the outer lamp panel also achieves a compact structure for the lighting device.

[0011] In a particularly preferred variant of the lighting device according to the invention, the one or more second light-emitting units are configured to generate a light distribution for daytime running lights and / or position lights and / or driving direction indicators and / or for surface illumination portions along the outer light panel and / or for contour illumination portions along the edges of the outer light panel. The surface illumination portions can, for example, be used within the range of a lighting scene to generate an attractive, dynamic light distribution, such as a welcome light when unlocking a motor vehicle.

[0012] In another embodiment of the lighting device according to the invention, at least one first light-emitting unit, and preferably each first light-emitting unit, is a light-emitting module, which includes a housing in which light-emitting devices for generating light distribution for low beam and / or high beam functions are arranged. The light-emitting devices may, for example, include one or more LEDs and / or laser diodes.

[0013] In another preferred embodiment of the invention, the housing of the first light-emitting unit, designed as a light-emitting module, is connected to an outer lamp plate via a flexible connecting device. Preferably, the flexible connecting device is a sleeve having two opposing open ends, wherein one end of the sleeve—preferably surrounding the light emission outlet—is fastened to the housing of the light-emitting module, and the other end of the sleeve is fastened to the outer lamp plate.

[0014] To prevent dirt or other particles from entering the first light-emitting unit designed as a light-emitting module, the sleeve is made of a dustproof material in a preferred embodiment and is sealed at its ends to the housing and outer lamp plate of the first light-emitting unit.

[0015] In another preferred embodiment, at least one second light-emitting unit, and preferably each second light-emitting unit, is a light-emitting module comprising a housing in which light-emitting devices are arranged for generating a light distribution different from that for the low beam and high beam functions. The light-emitting devices may, for example, include one or more LEDs and / or laser diodes.

[0016] In a particularly preferred embodiment, the housing of the second light-emitting unit, designed as a light-emitting module, is (mechanically) rigidly and preferably directly (i.e., without bridging components) connected to the outer lamp panel, thereby ensuring simple assembly of the lighting device. The rigid (mechanical) connection can vary depending on the design. In particular, it can involve material-locking and / or force-locking and / or form-locking connections.

[0017] In another design, at least one second light-emitting unit includes a planar light conductor. The planar light conductor can be rigidly connected to the outer light panel or, if necessary, spaced apart from the outer light panel, depending on the design.

[0018] In another preferred design, in addition to the first and second light-emitting units, the lighting device according to the invention also includes one or more radiation units for emitting radiation different from light, for example, in the form of one or more radar devices and / or lidar devices. Through this variation, functional units that do not have light-emitting functions but perform other tasks (especially distance measurement) are integrated into the lighting device according to the invention.

[0019] In a preferred variation of the embodiment just described, at least one radiating element, and if necessary, each radiating element, is rigidly and preferably directly (i.e., without bridging components) connected to the outer lamp panel, thereby ensuring a compact structure of the lighting device. The rigid (mechanical) connection can vary depending on the design. In particular, it can involve material-locking and / or force-locking and / or form-locking connections.

[0020] In another preferred embodiment, the outer lamp panel of the lighting device is made of plastic, which may include, for example, polyurethane. This reduces the weight of the outer lamp panel. Preferably, the plastic is an easily manufactured multi-component injection molded part. Furthermore, multi-component injection molding allows for the simple construction of translucent and opaque areas within the outer lamp panel.

[0021] In another preferred variation, the inner surface of the lighting device, visible through the outer lamp panel, has an absorption rate of 50% or more, particularly 90% or more, of light. In other words, the visible inner area of ​​the outer lamp panel is designed to be dark, thereby achieving an attractive, cool appearance of the lighting device in the form of a continuous, dark surface.

[0022] In another preferred embodiment, the outer lamp plate of the lighting device according to the invention, when installed in the motor vehicle, has an extension in the lateral direction of the motor vehicle, the extension extending substantially from the edge of the motor vehicle to the center of the motor vehicle. This achieves an attractive design, completely abandoning the design of a kidney-shaped device in the front of the motor vehicle.

[0023] In addition to the lighting device according to the invention, the invention relates to a motor vehicle that includes one or more lighting devices according to the invention or one or more preferred variations of the lighting device according to the invention. Attached Figure Description

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] In the attached diagram:

[0026] Figure 1 A schematic diagram of one embodiment of the lighting device according to the present invention is shown in a top view looking at its outer lamp panel;

[0027] Figure 2 shows along Figure 1 A cross-sectional view of line L1;

[0028] Figure 3 shows along Figure 1 A cross-sectional view of line L2;

[0029] Figure 4 shows along Figure 1 The cross-sectional view of line L3; and

[0030] Figure 5 shows a detailed view of the cropped portion in Figure 4. Detailed Implementation

[0031] Embodiments of the present invention will now be described with reference to a motor vehicle lighting device in the form of a left headlight. This headlight... Figure 1 The diagram schematically shows a top view of the front of a motor vehicle as seen from the front, and is indicated by reference numeral 1. The headlight includes an outer lamp panel 2, which is a multi-component injection-molded part, as will be described in more detail below. Here, the majority of the outer lamp panel is translucent to allow light to be emitted from the lighting device. Inside the lighting device are multiple light-emitting units, or more precisely, light-emitting modules, which... Figure 1 The image is shown only schematically by presenting its outline.

[0032] The main light module 3 is located in the right-side region of the outer light panel 2. This main light module is configured to generate the low beam and high beam of the motor vehicle and is the first light-emitting unit in this application. The main light module includes two optical devices 3b and 3c, which are shown only schematically. The low beam and high beam are generated by means of light from a light source (not shown) arranged behind the optical device.

[0033] Above the main light module 3, behind the outer light panel 2, are two signal light units, or more precisely, signal light modules 4 and 4', which are, in the sense of this application, the second light-emitting units. The signal light units are... Figure 1 The symbols are only schematically shown and collectively used to generate daytime running lights during driving in bright light and position lights during driving in darkness. When generating daytime running lights and position lights, the signal light unit emits white light. Furthermore, signal light unit 4 also functions as a driving direction indicator. That is, activating the driving direction indicator causes signal light unit 4 to flash yellow, thereby deactivating the daytime running lights or position lights function of the signal unit during the flashing period. After the flashing ends, the signal light unit again emits white light as daytime running lights or position lights. In the following area of ​​the outer light panel 2, the entire surface of the outer light panel is translucent, thereby effectively ensuring the generation of low beam or high beam and signal light functions with minimal energy loss. The main light module 3 and signal light units 4 and 4' are located behind this area.

[0034] Next to the main light module 3 and the signal light units 4, 4', on the left side, there is a surface illumination section 5, the outline of which is shown only by dashed lines, and this surface illumination section is, in the sense of this application, a (further) second light-emitting unit. The surface illumination section is arranged behind the stripe pattern 8 (see Figures 2 to 4) of the outer light panel 2 and generates a light surface within its outline when activated, thereby making the light-emitting strips on the outer light panel visible based on the stripe pattern 8. If necessary, a pattern different from the stripe pattern may exist on the outer light panel in the area of ​​the surface illumination section, or there may be no pattern at all.

[0035] The surface illumination unit is preferably used in lighting scenarios. Here, the surface illumination unit can be manipulated so that it illuminates only a portion of its outline, thereby generating dynamic lighting motion. This can be used, for example, in a welcoming scenario when a driver unlocks a vehicle. In the welcoming scenario, the surface illumination units 5 in the two headlights, when combined with position lights, generate an attractive dynamic light pattern, thereby welcoming the driver.

[0036] Furthermore, the headlight 1 includes a so-called contour lighting section 6, which is only schematically shown as a dotted surrounding line on the edge of the outer lamp panel. The contour lighting section is implemented by a surrounding light conductor, as will be described in more detail below. Activating the contour lighting section achieves an attractive appearance for the front of the vehicle.

[0037] Furthermore, the headlight 1 includes a radar 7, which is arranged below and beside the surface illumination section 5 in the left-side region of the outer light panel 2. Figure 1 Only the outline of the radar is shown. This radar emits a radar beam and detects the received radar echo to measure the distance to objects. The radar is used in driver assistance functions such as pedestrian warnings or active speed control. A striped pattern 8 located in front of the surface illumination unit 5 also extends onto the radar 7. However, the striped pattern is transparent to the wavelength of radar radiation, so the intensity of the emitted radar radiation is not impaired by the striped pattern.

[0038] In addition, Figure 1 The diagram also shows three dashed lines L1, L2, and L3 representing the cutting lines, with corresponding cross-sections along these lines shown in Figures 2 through 5. Here, the cutting is performed horizontally along the corresponding lines, with Figures 2 through 5 showing the vertical line of sight to each cross-section from top to bottom.

[0039] In the embodiment of headlight 1 described here, the inner surface of the headlight, visible through the outer lamp panel 2, is designed to absorb light or to be dark. In this way, a substantially dark surface is formed in the area of ​​the outer lamp panel for the observer in the cold appearance of the headlight (i.e., when the headlight is off). Furthermore, the outer lamp panel 2 extends almost to the center of the vehicle from the left edge, or more precisely, the fender, in the lateral direction of the vehicle. Thus, an attractive image of a continuous surface on the front of the vehicle is achieved by the headlights mounted on both sides. Here, the integration of the kidney-shaped device at the front of the vehicle is abandoned.

[0040] Furthermore, the outer light panel 2 ends flush with the bumper trim 10 at the front of the vehicle (see Figures 2 to 4), thus achieving an aesthetically pleasing design. However, a problem arises when a low-speed collision occurs at the front of the vehicle (e.g., during a parking scramble), a direct force is applied to the outer light panel 2 because there is no arched bumper area below the headlights. This force may cause displacement or damage to the light-emitting units mounted in the headlights. To avoid this problem, the light-emitting units are arranged in a special manner behind the outer light panel, as explained in more detail below with the aid of Figures 2 to 5.

[0041] Figure 2 shows along Figure 1 The cross-section of line L1 extends through the contour lighting section 6, the surface lighting section 5, and the upper signal light unit 4. The outer light panel 2 is a component made of multiple plastic components manufactured by multi-component injection molding, including an external light-transmitting component, or layer 2a, a light-transmitting film 2b applied to layer 2a, and another component in the form of an opaque layer 2c. This opaque layer is only provided in a portion of the film 2b and is used to secure the signal light units 4, 4', surface lighting section 5, contour lighting section 6, and radar 7. Furthermore, as can be seen from Figure 2, the outer light panel 2 ends flush with the bumper trim panel indicated by reference numeral 10.

[0042] In the area of ​​the outer light panel, the surface illumination unit 5 emits light in this area, and the aforementioned striped pattern 8 is printed on the film 2b. Additionally, a decorative section 9 is printed in this area, which becomes visible when the surface illumination unit is activated. In the embodiment described herein, the decorative section refers to the vehicle manufacturer's badge or logo. Unlike the surface illumination unit 5, neither the striped pattern nor the decorative section exists in the area of ​​the outer light panel behind the main light module 3, signal light units 4, 4', and contour illumination unit 6.

[0043] According to Figure 2, the signal light unit 4 includes a housing 4a open towards the outer light panel 2, a light-emitting device in the form of a circuit board 4b equipped with LEDs, and a scattering optical device 4c arranged in front of the circuit board, all located within the housing. The LEDs can emit different colors, thus achieving not only a flashing function (emitting yellow light) but also a daytime running light function or a position light function (emitting white light). The signal light unit 4 and the components thereof... Figure 1 The visible signal light unit 4', which has the same structure as the signal light unit 4, is rigidly connected to the outer light plate 2 via a housing 4a, wherein, in the embodiment described herein, the housing 4a is bonded to the layer 2c.

[0044] The surface illumination unit 5 is constructed similarly to the signal light unit 4. That is, the surface illumination unit includes a housing 5a that opens toward the outer lamp panel 2 and includes a light-emitting device in the form of a circuit board 5b equipped with LEDs and a diffusing optical device 5c arranged in front of the circuit board. The surface illumination unit is also rigidly connected to the outer lamp panel 2 by bonding the housing 5a to the layer 2c of the outer lamp panel 2.

[0045] Furthermore, a cross-section of the surrounding contour lighting section 6 can be seen in Figure 2. The contour lighting section here comprises a housing 6a that opens toward the outer lamp panel and surrounds the edge of the outer lamp panel, within which a light conductor 6b is located. Light is supplied to the light conductor at one end via a light source (not visible in the figure). This light is coupled out from the light conductor via a coupling structure on the side of the light conductor 6b adjacent to the housing 6a, thereby producing the surrounding contour light. The inner side of the housing 6a is designed to be reflective, thereby increasing the brightness of the contour lighting section. Similar to the signal light units 4, 4' and the surface lighting section 5, the contour lighting section 6 is also rigidly connected to the outer lamp panel 2 by bonding the housing 6a to the layer 2c of the outer lamp panel. By rigidly fastening the light-emitting units 4, 4', 5, and 6 to the outer lamp panel 2, a compact headlight structure is achieved on the one hand, and damage to these light-emitting units is avoided by the force exerted by the outer lamp panel, as the light-emitting units move together with the outer lamp panel.

[0046] Figure 3 shows along Figure 1 The cross-section of line L2. This line extends through the contour lighting section 6, the surface lighting section 5, and the main light module 3, the interior of which is not shown in cross-section. As can be seen, the main light module 3 includes a housing 3a with an open front side, or more precisely, a light emission outlet 3d, through which light generated in the main light module is emitted through optics 3b and 3c. Due to the size or depth of the main light module 3, a rigid connection between the module and the outer lamp plate 2 is no longer feasible. Furthermore, the main light module includes a lighting range adjustment device for adapting the low beam headlights to the vehicle's mounting, making a rigid fastening of the main light module to the outer lamp plate impossible for this reason.

[0047] Nevertheless, to prevent the main light module 3 from moving or being damaged by the movement of the outer light panel 2 in the event of a collision, the main light module 3 is arranged spaced apart from the outer light panel 2. Here, to prevent dirt or other particles from entering the interior of the housing 3a through the light emission outlet 3d, an outer cover or sealing sleeve 11 is provided between the main light module 3 and the outer light panel 2. The end of the sealing sleeve adjacent to the housing 3a of the main light module 3 surrounds the light emission outlet 3d and is sealed and fastened to the housing, as described below with reference to FIG. 5. The end of the sealing sleeve adjacent to the outer light panel 2 is also sealed and mounted on the layer 2c of the outer light panel, as will also be described in more detail with reference to FIG. 5.

[0048] Figure 4 shows along Figure 1 The cross-section of line L3 extends through contour illumination unit 6, radar 7, surface illumination unit 5, and main light module 3. As shown in Figure 4, radar 7 includes a transmitting and receiving unit 7a for transmitting radar beams and receiving corresponding radar echoes. Similar to the light-emitting units 4, 4', 5, and 6, radar 7 is also rigidly connected to the outer light panel 2. For this purpose, a funnel-shaped retainer 7b is mounted on the transmitting and receiving unit 7a, which is bonded to layer 2c of the outer light panel. This rigid fastening resists radar damage caused by the movement of the outer light panel 2 in the event of a collision, since the radar moves together with the outer light panel.

[0049] Figure 5 shows a detailed view of the main light module 3 and its fastening to the outer light panel 2, where the contour lighting section 6 has been omitted for clarity. As can be seen, the sealing sleeve 11 connecting the main light module 3 to the opaque layer 2c of the outer light panel 2 is made of plastic composed of two different components. The edges 11a of the sealing sleeve 11 are made of a mixture of polycarbonate and ABS plastic (ABS = acrylonitrile-butadiene-styrene). In contrast, the middle section 11b of the sealing sleeve is made of TPE plastic (TPE = thermoplastic elastomer). The TPE plastic ensures the flexibility of the sealing sleeve 11. The edge of the sealing sleeve 11 adjacent to the outer light panel 2 is bonded to the layer 2c of the outer light panel via polyurethane adhesive 14. Conversely, the opposite edges of the sealing sleeve 11 are secured to the main light module 3 via a total of eight metal clips 13, two of which are visible in Figure 5. Here, the main optical module includes a surrounding protrusion 3e, which is pressed against the protrusion 11c of the sealing sleeve by a sealing element 12 made of EPDM material (EPDM = ethylene propylene diene monomer rubber). The pressure is generated by a metal clip 13. With this structure, the components of the main optical module 3 exposed via the light emission outlet 3d are very well protected against the intrusion of dust or other particles.

[0050] Other sealing methods can be used instead of the sealing sleeve. The sealing sleeve can also be made of other materials or fastened to the main optical module or external lamp panel in other ways. For example, instead of fastening by clamp, fastening by adhesive, clamping, etc., can be used.

[0051] The embodiments of the present invention described above have a number of advantages. In particular, they provide a motor vehicle lighting device in the form of a headlight, whose components are well protected from damage in the event of a low-speed collision. This is achieved, on the one hand, by the spacing between the main light module and the outer lamp panel, and on the other hand, by the rigid mechanical connection between another light-emitting unit and the outer lamp panel. In this way, movement or shifting of the outer lamp panel prevents immediate damage to the light-emitting units mounted in the headlight during a collision with low force. Furthermore, by arranging the light-emitting units directly on the outer lamp panel, a compact structure of the lighting device is ensured. However, it is also possible that one or more of the light-emitting units rigidly connected to the outer lamp panel in the above embodiments may also be spaced apart from the outer lamp panel.
