Description

Technical Field

[0001] The present disclosure relates to a lighting device for a rear-view device of a vehicle. More specifically, the present disclosure relates to a lighting device for providing turn signal lights and other multi-functional lamp arrangements. The invention also relates to a rear-view device having such a lighting device and a vehicle having such a rear-view device. Background Art

[0002] Vehicles generally include rear-view devices mounted inside and outside the vehicle. The rear-view device generally includes one or more mirrors, cameras, or any combination thereof for observing at least the scene around the rear end of the vehicle, and one or more lighting devices.

[0003] The term "vehicle" denotes any motor vehicle, with or without a trailer, driven by a driver, where the driver requires information about persons, other vehicles, or objects in the vicinity of the vehicle in order to be able to drive safely. By way of example, the vehicle is a car, a truck, a tractor, or a trailer.

[0004] The term "rear-view" is defined herein as the observation of the surrounding area that is not within the field of view of the driver of the vehicle, i.e., the directions opposite to, to the left, right, below, and above the observation direction, but may also include the observation in the direction of the driver's observation direction and / or the observation in any combination of directions.

[0005] The terms "driver" and "driver of the vehicle" herein refer to a person who controls the main parameters of the vehicle, such as direction, speed, and / or altitude, e.g., typically a person located in a position designated for the control person (e.g., a seat), but may also refer to any other person or entity inside or outside the vehicle.

[0006] The term "light source" denotes a device from which light is generated and emitted. The light source may include one or more light-emitting devices or solid-state light sources. The term "solid-state" generally refers to light emitted by solid-state electroluminescence rather than by an incandescent bulb or a fluorescent tube. For example, the light source may include a semiconductor light-emitting diode (LED) or a laser diode, an organic light-emitting diode (OLED), a polymer light-emitting diode (PLED), an LED lamp package, an LED chip, or an LED die, or an array composed of one or more of these devices. It should be understood that the light source may also include a color-changing LED, i.e., the LED can be configured to change color when needed.

[0007] The term "light guide" refers to a light-conducting element that at least partially forms part of a housing, where the light guide has: a light-receiving surface located within the outer housing, which can be at least partially provided by the housing; and a light-emitting surface located outside the outer housing, such that light emitted from a light source is received by the light-receiving surface of the light guide and guided towards the light-emitting surface of the light guide, such that light is emitted from the light guide. The light guide can be made of a transparent material. Light can be emitted from the light guide with a uniform brightness over the entire light-emitting surface.

[0008] The term "reflective element" refers to a reflective surface, such as the surface on which light emitted from the light guide falls and is reflected along a reflection direction to emit reflected light. The reflective element can be a polished or coated surface that provides a mirror-like surface finish.

[0009] Different functions and devices can be incorporated into and / or controlled by means of a rear-view device. Of particular interest are functions and devices that enhance, extend, and / or maintain the functionality of the rear-view device during normal or extreme conditions. Corresponding facilities can include heating and / or cooling facilities, cleaning facilities (such as wipers, liquid and / or gas sprays), actuator facilities for moving the rear-view device or parts thereof (such as a display, a camera system, and / or parts of a camera system, including for example lenses, filters, light sources, adaptive optics such as deformable mirrors, sensors, and / or mirrors); and / or actuator facilities for causing other objects (such as parts of a vehicle and / or objects around the vehicle) to move. In addition, a linear track and / or a rotating wheel for exchanging optical elements, such as a filter wheel, can be included, where the optical elements include for example lenses, mirrors, light sources, sensors, adaptive optics such as deformable mirrors, and / or filters.

[0010] Prominent examples of functions and devices incorporated into and / or controlled by means of a rear-view device include lighting devices, for example in the form of any type of lamp module, such as an external lamp module, an internal lamp module, a headlamp, a rear lamp, a fog lamp, a brake lamp, an acceleration lamp, a turn signal indicator lamp, a marker lamp, a puddle lamp, a flash lamp, a navigation lamp, a position lamp, an emergency lamp, a spotlight, a green lamp, a red lamp, a warning lamp, a turn signal lamp module, an approach lamp, a searchlight, an information lamp, a display, and / or any combination thereof.

[0011] In recent years, lighting devices for vehicles have become important due to their aesthetic appeal to consumers. Therefore, vehicle manufacturers have made efforts in designing vehicle lighting devices in consideration of the styling of the vehicle on which the lighting device is installed. In addition, vehicle manufacturers can provide optional lighting effects (in addition to the legally required lighting functionality) to enhance the vehicle styling.

[0012] It is difficult to provide an aesthetically appealing vehicle lighting device that meets the required technical specifications. For example, the taillights of existing automobiles tend to be energy-intensive and require various components, such as reflectors. The same is true for headlights in that they require multiple components, such as reflectors, cut-off devices, etc. An aesthetic lighting effect results in a greater number of components and higher complexity. Such vehicle lighting devices are not easily adaptable to the styling of the vehicle.

[0013] Rearview devices with lighting devices for providing signals such as turn signals, warning lights, fog lights, etc. are commonly used in vehicles. These lighting devices not only enhance or expand the functionality of the rearview device but also provide aesthetic appeal to the vehicle. The lighting device of the rearview device may include a light source such as a light-emitting diode (LED) and an optical waveguide that is irradiated to provide a signal outside the vehicle. These lighting devices can be further enhanced to emit a light pattern that not only provides lighting functionality to the vehicle but also provides aesthetic appeal and enhances the styling of the vehicle. Summary of the Invention

[0014] The object of the present disclosure is to further enhance the aesthetic appeal and styling of known lighting devices for rearview devices of motor vehicles.

[0015] This object is achieved by a lighting device for a rearview device adapted to be used with a vehicle, the lighting device comprising: at least two light sources arranged to emit light beams, wherein the at least two light sources include a first light source and a second light source, and the light beams include a first light beam having a first color in particular and a second light beam having a second color different from the first color in particular; at least two optical waveguides, wherein the at least two optical waveguides include a first optical waveguide and a second optical waveguide; a housing, wherein the housing includes an upper part, a lower part, and a support element for detachably supporting at least two light sources and / or at least two optical waveguides in particular; at least one reflecting element arranged to reflect at least a part of the light beam from one of the at least two light sources and supported by the support element; a transparent lens at least partially arranged between the upper part and the lower part of the housing; and at least one pattern generating element configured to generate at least one light pattern using at least a part of the light beam from one of the at least two light sources.

[0016] It is proposed that the first light source is integrally coupled to the first optical waveguide to emit the first light beam in a first light portion, and the second light source is integrally coupled to the second optical waveguide to emit the second light beam in a second light portion, wherein in particular the first light portion and the second light portion are arranged to be substantially parallel to each other.

[0017] Further proposed is that a second light source is arranged between the first light source and at least one reflecting element, and / or a second light guide is arranged between the support element and the first light guide, and / or the second light source and / or the second light guide are configured to produce an indirect light effect.

[0018] Features of embodiments of the present invention may lie in that the first light source is a color-changing light source and / or cooperates with a color-changing element, and / or the second light source is a color-changing light source and / or cooperates with a color-changing element.

[0019] Features of the embodiment may also lie in that the first light guide includes a transparent lens, and / or the first light guide extends towards the bottom of the rear-view device, and / or the first light guide is configured to allow a second light beam to pass through the transparent lens after being reflected from at least one reflecting element.

[0020] Further, proposed is that at least one pattern generating element is arranged on or provided by the transparent lens, and / or at least one pattern generating element is arranged on or provided by at least one reflecting element, and / or at least one pattern generating element is configured to be located at a second light portion.

[0021] In this regard, also proposed is that at least one reflecting element is configured with at least one pattern generating element for generating at least one light pattern using the second light beam.

[0022] An embodiment may be defined as that at least one pattern generating element is one of at least one mask for forming a pattern, logo, symbol, icon or text, at least one 2D / 3D profile on at least one reflecting element, and at least one notch on at least one reflecting element.

[0023] In this regard, proposed is that at least one pattern generating element is fully spread on at least one reflecting element, or partially spread to at least one part of at least one reflecting element.

[0024] Furthermore, an embodiment may also include a light-shielding element clamped between the first light source and the second light source so as to block the light beams facing each other.

[0025] Also proposed is that at least two light sources are arranged behind the housing, particularly behind the upper part of the housing, and / or at least one of the at least two light sources includes a color-changing light source and / or cooperates with a color-changing element, and / or at least one of the at least two light sources is switchable between an on state and an off state.

[0026] The lighting device of the present disclosure can be a multi-purpose lighting device that exposes light to the outside of the rear-view device to achieve direct light emission and indirect light emission. The lighting device uses at least two light sources to emit light in a single output direction. At least one of the light sources can be hidden to prevent direct observation from the outside of the rear-view device, in order to achieve the desired light aesthetics, while also allowing for better encapsulation of the rear-view device arrangement.

[0027] The first light source is coupled to the first light guide to provide a uniform distribution of the first light beam emitted by the first light source. The second light source is coupled to the second light guide for uniformly distributing the second light beam emitted by the second light source. The second light beam is reflected back using at least one reflecting element, such as placed below the second light guide, so that the second light beam emitted from the second light guide is reflected from at least one reflecting element and exits from the bottom of the first light guide.

[0028] Furthermore, a transparent lens extends from the first light guide towards the bottom end of the rear-view device, such that the second light beam can only exit the rear-view device after being reflected by at least one reflecting element. The second light source coupled to the second light guide is hidden behind the first light source and the first light guide in order to provide a dim / indirect / holographic output of the second light beam.

[0029] Therefore, the light emitted by the two light sources provides two parts, namely, the first light part that is directly irradiated and the second light part that is indirectly irradiated. When the lighting device, together with the rear-view device including the lighting device, is installed in a vehicle, the two light parts can extend parallelly, preferably extending substantially horizontally.

[0030] According to the present disclosure, at least one pattern generating element can be provided by a reflecting element or disposed on a lens that can be formed by the first light guide.

[0031] The present disclosure also provides a rear-view device that includes at least one lighting device according to the present disclosure.

[0032] The present disclosure also provides a vehicle that includes at least one rear-view device having at least one lighting device according to the present disclosure. Description of the Drawings

[0039] It should be understood that the described embodiments are merely examples of the present disclosure, and the present disclosure can be implemented in various and alternative forms. The drawings are not necessarily drawn to scale; some features may be enlarged or minimized to show details of specific components. Therefore, the specific structural and functional details disclosed herein should not be construed as restrictive, but only as a representative basis for teaching those skilled in the art to adopt the present disclosure in different ways.

[0040] Figure 1a and Figure 1b show a rearview device 200 having a lighting device 100 of a vehicle 300, wherein Figure 5Vehicle 300 is shown. The rear view device 200 includes a head portion 202 and a base portion 204. In one embodiment, the rear view device 200 is mounted on the vehicle 300 on either side of the vehicle 300 by coupling through the base portion 204, where the base portion 204 can have various designs, including but not limited to door-mounted designs, window-mounted designs, etc. The rear view device 200 is configured to observe the surrounding environment of the vehicle 300, particularly the rear view of the vehicle 300. The rear view device 200 may include a mirror (not shown). The rear view device 200 may further include at least one camera 206 for acquiring the rear view of the vehicle 300 to be displayed as an image or video by a display unit (not shown) installed inside the passenger compartment of the vehicle 300. The rear view device 200 further includes a lighting device 100. The lighting device 100 can be used to provide at least one of a turn signal, a warning signal, a fault signal, a home signal, an autonomous driving mode, a parking signal, a positioning lighting, and a welcome signal. In addition to providing the signals, the lighting device 100 can enhance the aesthetic appeal of the vehicle 300 according to the present disclosure.

[0041] In Figure 1a and Figure 1b In the illustrated embodiment, two light outputs are visible, one light output in the form of a first light portion 104 of the lighting device 100 at the top and one light output in the form of a second light portion 105 of the lighting device 100 at the bottom. The outputs from the two light portions 104, 105 enhance the aesthetic appeal and styling of the vehicle 300. This is even more the case when using the pattern generating element 120 explained in further detail below.

[0042] The lighting device 100 includes a housing 102. The housing 102 can at least partially constitute an external portion of the rear view device 200. The housing 102 can be made of an opaque material such as a polymer, a metal, an alloy, and various natural materials. The housing 102 includes an upper housing portion 102a and a lower housing portion 102b, also see Figure 2 . The upper housing portion 102a and / or the lower housing portion 102b have cutouts that allow the light from the lighting device 100 to exit the rear view device 200.

[0043] Figure 1a 、 Figure 1b A portion of the rear view device 200 is shown, which shows the lighting device 100. The lighting device 100 includes two light sources 106a and 106b, and the two light sources can be arranged behind the housing 102 such that the two light sources 106a and 106b are not visible from the outside, as Figure 1a shown, where in Figure 1bThe part located behind the housing 102 is shown within the dashed lines to illustrate the positions and arrangements of the two light sources 106a and 106b within the housing 102.

[0044] In addition, as Figure 2 shown, the second light source 106b is sandwiched between the support element 116 of the housing 102 and the first light source 106a, such that the second light source 106b is hidden and can produce an indirect light effect. The two light sources 106a and 106b can include, but are not limited to, semiconductor light-emitting diodes (LEDs) or laser diodes, organic light-emitting diodes (OLEDs), polymer light-emitting diodes (PLEDs), LED lamp packages, LED chips or LED die, or an array composed of one or more of these devices.

[0045] In one embodiment, the two light sources 106a and 106b can be pre-configured with different colors in order to create a visual difference for an observer viewing the lighting device 100 and to distinguish the uses of the light. For example, the first light source 106a can be yellow / orange to produce a turn signal light, while the second light source 106b can be blue to produce a home light. In an alternative embodiment, the two light sources 106a and 106b can include color-changing LEDs to obtain various color outputs from one LED. The advantage of using color-changing LEDs as light sources is that multi-colored light can be emitted from the lighting device for indicating different functions and / or enhancing the aesthetic appeal of the vehicle. For example, to emit a turn signal light, the LED can be switched to yellow, to emit a home signal, the LED can be switched to blue, or to emit a warning signal, the LED can be switched to red.

[0046] The lighting device 100 further includes two light guides, namely a first light guide 108a and a second light guide 108b. The first light guide 108a is coupled to the first light source 106a such that the first light guide 108a emits a first light beam L1 from the first light source 106a uniformly over an entire part (especially the upper part) of the length of the first light guide 108a, as shown in Figure 2 and Figure 3a . Further, the second light guide 108b is coupled to the second light source 106b such that the second light guide 108b emits a second light beam L2 from the second light source 106b uniformly over an entire other part (especially the lower part) of the length of the first light guide 108a, also shown in Figure 2 and Figure 3b .

[0047] As Figure 2 and Figure 3bAs shown, first, the second light guide 108b emits a second light beam L2 towards the bottom end of the rearview device 200. Then, the second light beam L2 is reflected by at least one reflection element 118 and indirectly emitted towards the external direction of the rearview device 200 as shown by the path of the second light source L2, passing through another part (lower part) of the first light guide 108a that forms the transparent lens 113 along the way. The transparent lens 113 extends from the upper part of the first light guide 108a that emits the first light beam L1 towards the bottom end of the rearview device 200. The transparent lens 113 also serves as a cover to prevent dust or debris from entering the compartment of the second light guide 108b and the reflection element 118. Although in Figure 2 the lens 113 is shown as being formed together with the first light guide 108a, the lens can also be provided as an additional part (not shown) attached to the housing parts 102a, 102b.

[0048] In addition, as Figure 2 shown, the second light guide 108b is sandwiched between the support element 116 and the first light guide 108a, so that the second light guide 108b is hidden and can produce an indirect light effect. Moreover, the lighting device 100 can include a light-shielding element 110 placed between the first light guide 108a and the second light guide 108b to block the light transmitted between the first light guide 108a and the second light guide 108b.

[0049] The two light guides 108a and 108b are detachably mounted on the housing 102 at the light guide support element 116. The light guide support element 116 is a part of the housing 102 configured to support and fix the light guides 108a and 108b. The light guides 108a and 108b are mounted on the light guide support element 116 via at least one of screws, nuts, adhesives, snap fits, butt joint straps, clamping connections, plug-in connections, etc. (not shown).

[0050] The reflection element 118 can be provided on the housing 102, particularly on its support element 116, such that the reflection element 118 is configured to face the transparent lens 113, as Figure 2 shown. The reflection element 118 is configured to direct light towards the outside of the lighting device 100. The reflection element 118 can also be configured with at least one pattern generating element 120 for emitting light in the form of a pattern, logo, symbol, icon, text, or a combination thereof, as Figure 1a and Figure 3bAs shown. At least one pattern generation element 120 disposed on at least one reflective element 118 is adapted to generate at least one light pattern using a second light beam L2. The pattern generation element 120 is one of at least one mask for forming a pattern, logo, symbol, icon or text, at least one profile on at least one reflective element 118, and at least one notch on at least one reflective element 118. The pattern generation element 120 is spread completely or partially on at least one reflective element 118.

[0051] In Figure 1a , Figure 3b , Figure 4a and Figure 4b are shown patterns, logos, symbols, icons, texts or combinations thereof generated by the pattern generation element 120. In these embodiments, the reflective element 118 includes the pattern generation element 120 such that when light falls on the reflective element 118 having the pattern generation element 120, the reflected light is emitted in the form of a pattern, logo, symbol, icon, text or combination thereof. The pattern generation element 120 may include at least one of a laser printing part, a notch, a masking part and / or etching, 3D printing, inkjet printing, molding 2D or 3D drawing shapes for forming a pattern, logo, symbol, icon or text.

[0052] In an alternative embodiment, the pattern generation element 120 may be disposed on the transparent lens 113 to produce the same effect as explained above.

[0053] Figure 4a Shows an illumination device 100 having a first light source 6a in an on state and a second light source in an off state. Figure 4b Shows an illumination device 100 having a first light source 6a in an off state and a second light source in an on state. As Figure 1a explained by the illustrated cross-section of, the first light source 106a is responsible for irradiating the first light portion 104, while the second light source 106b is responsible for irradiating the second light portion 105. Thus, as Figure 4a shown, when the first light source 6a is in the on state and the second light source is in the off state, the first portion 104 of the illumination device 100 emits light / irradiates, and the pattern generation element 120 can be seen through the lens 113. The first light portion 104 may indicate a hazard light or a turn indicator light.

[0054] As Figure 4bAs shown, when the first light source 6a is in the off state and the second light source is in the on state, the second part 105 of the lighting device 100 emits light / irradiates, thereby creating an indirect lighting effect due to the arrangement of the components including the second light guide 108b. The reflecting element 118 is configured such that the second light beam L2 emitted from the second light source 106b and uniformly distributed by the second light guide 108b is guided along a direction towards the bottom and falls on the reflecting element 118 having the pattern generating element 120, and the reflecting element is set at an angle so that the second light beam L2 is emitted through the transparent lens 113 and thus a faint or hologram-like 2D / 3D image or text pattern can be seen. The angle between the reflecting element 118 and the second light beam L2 can be between 20° and 80°.

[0055] Figure 5 A front view of a vehicle 300 according to the present disclosure is shown, which shows the rearview device 200 and the lighting device 100. The lighting device 100 can be provided on the rearview device 200 or integrated therein.
