CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application Serial No. 62/906,380 filed September 26, 2019, the entire contents of which are herein incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field

[0002] The disclosed embodiments relate generally to the field of automotive exteriors. More specifically, the field of automobile lighting and/or fascia systems and arrangements.

2. Description of the Related Art

[0003] Vehicle exteriors often include both functional and ornamental features. With respect to lighting, some lighting arrangements are primarily functional, e.g., headlights and signal lights. These features, however, can also include ornamental aspects, e.g., may be designed for appealing appearance in addition to performance.

[0004] Other exterior features unrelated to lighting, e.g., fascias, can be decorated ornamentally, or designed to conform to an overall vehicle appearance, or to accomplish aerodynamic schemes. Most commonly, fascia panels are implemented into the front and rear of a vehicle. The facias can be incorporated at, e.g., the vehicle’s headlamp area, grill, bumper, side paneling, into or near a taillight arrangement, as well as other locations.

SUMMARY

DETAILED DESCRIPTION

[0019] Embodiments provide systems including a multi-lens lighting arrangement for vehicles used as a part of or as a replacement for a fascia.

[0020] The following detailed description references the accompanying drawings that illustrate specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled. [0021] In this description, references to “one embodiment,” “an embodiment,” or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment,” “an embodiment,” or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the technology can include a variety of combinations and/or integrations of the embodiments described herein.

[0022] An embodiment 100 shown in FIG. 1 includes a vehicle 102. The vehicle includes a passenger-side fascia section 104, a center fascia section 106, and a driver’ s-side facia section 108. In the disclosed embodiment, each of sections 104, 106, and 108 includes a first passenger-side module 110, a second central module 112, and a third drivers-side module 114, respectively. It should be understood that the embodiments disclosed herein should not be considered as limiting unless claimed. Those skilled in the art will recognize that broad concepts have and will be disclosed herein which could be embodied in numerous arrangements not shown.

[0023] Whereas FIG. 1 shows these modules as they appear when installed, and FIG. 2 shows the vehicle in a state where the modules are pulled out to reveal the pockets they are received into, e.g., pockets 116, 118, and 120.

[0024] In the disclosed embodiments, all of modules 110, 112, and 114 include top surfaces, side surfaces, and bottom surfaces. For example, looking at center module 112 in FIG. 2, in which it is removed, it can be seen that the module has upper housing wall 122, side walls 124 and 126, and a bottom wall 128 (not shown).

[0025] More details regarding the upper and bottom housing walls 122 and 128 can be seen in the cross section of FIG. 3. A plurality of LED packages 128 which provide light to the system can also be seen.

[0026] Referring to FIG. 3, it can be seen that these LEDs 228 are incorporated into a system 300. The light source 302 includes a PCB 304 onto which each of the in-line LEDs 228 (see FIG. 3) would go in and out of the page, and cannot all be seen in FIGs. 1 and 2, are mounted, controlled, and powered using known technologies. The light is extracted from the LED packages 304 (see also FIG. 1) into an edge 306 of a light guide plate 308. Reflective ink deposits 310 applied to the back of the light guide plate 308 (facing a first open space 309) serve to direct the light forward across an open chamber 312, into a first lens 314, then through a second open space 315, and then through a second lens 316 before leaving the housing.

[0027] As can be seen in the cross-section of FIG. 3, the inner and outer surfaces of the first lens 314 and second lens 316 have been modified by adding a paint or an ink in different locations, optionally on both sides. In embodiments, some of the light emitted from the source 302 is occluded or otherwise modified using a light-modifying substances applied in different locations on an inner and outer surfaces of each of the first and second lenses 314 and 316.

[0028] With respect to the first lens 314, the inner surface includes four areas onto which an ink or paint has been added. For example, in area 318 an opaque ink layer has been added for the purpose of blocking the emission of light therethrough. Immediately below that, in an area 320, a translucent ink has been added to modify the light, e.g., creating a desired color, decorative depiction, or other effect. A next area down 322 shows a lighter translucent ink with a color different than the one used in area 320. Immediately below that, area 324, in the FIG. 3 embodiment, is, like area 318, opaque, thus blocking light. The upper and lower opaque coatings 318 and 324 limit the light such that only the translucent colored/inked areas 320 and 322 allow for the passage of light. Although not evident from FIG. 3, each coated area (of areas 318, 320, 322, 324) extends into and out of the page in a uniform horizontal fashion, thus creating decorative indicia, rearward patterns supporting a three-dimensional design, or other configurations of diverse paints at different levels of the lens 308.

[0029] On the other (outer) side of the first lens 314, paints/inks have been applied to an area 326 as well as areas 328 and 330 in order to create (in combination of the coatings applied to the inner side, a three-dimensional effect when the device is illuminated, or not illuminated (e.g., in sunlight). Again here, although not evident from FIG. 3, each coated area (of areas 326, 328, and 330) extends into and out of the page in a uniform horizontal fashion, thus creating areas (e.g., bands or other shapes) of diversely deposited materials, e.g., paints at different levels of the lens 308.

[0030] Across the second gap/chamber 315, the second outer lens 316 includes three similar application areas 331, 332, and 333, each including a similar kind of paint (alternatively ink). Although these areas, in the disclosed embodiment, are identical or substantially similar coated stripes, those skilled in the art will recognize that each of areas 331, 332, and 333 could be painted differently depending on the desired effect. In the disclosed embodiment, the different areas have been made coated at different locations for the purpose of providing a three-dimensional layered effect, and colored appearance when being illuminated, or when not illuminated. On the outer side of lens 316, in the disclosed embodiments, three areas having different paint applications 334, 338, and 342 have been deposited, and these painted areas are spaced apart by again, differently painted areas 336 and 340. As can be seen in the FIG. 3 cross section, material deposition areas 336 and 340 are relatively short, and thus, serve to form curved bands which can be seen longitudinally in FIG. 1. Deposition area 338 forms a larger central curved band as can be seen in FIG. 1. FIG. 1 also shows that the uppermost and lowest material deposition areas 336 and 342 are used to create an illuminated different colored backing for the image represented by material deposition areas 336, 338, and 340.

[0031] The deposited material areas (painted/printed/coated) 334, 336,

338, 340, and 342 exist immediately underneath a transparent covering (or lens) 344. Because of this, the areas 334, 336, 338, 340, and 342 can be seen in FIGs. 1 and 2. The LEDs 306 for the FIG. 3 version are also shown in FIGs. 1-2 for the purpose of showing locations along the length, but have been brought out of the background because they would not be seen in the disclosed embodiment.

[0032] It should be noted, that any of areas 318, 320, 322, 324, 326, 328, 330, 331, 332, 333, 334, 336, 338, 340, and 342 could each include any variety or combination of ink, coatings, etc. of any light modifying characteristic for the purpose of creating any three-dimensional or other desired effect. One example of a three- dimensional effect which might be advantageously created is that of a three- dimensional rendering of a logo complete with colors, graphics, indicia, and other matter. Numerous other graphics, could , of course be implemented using the systems and methods described herein.

[0033] The embodiment of a sine-wave configuration disclosed in FIGs. 1-2 is only an example of a graphical effect, thus should not be considered limiting. It should also be understood that because of the various material depositions made on the first and second lenses 314 and 308 behind these foremost material deposition areas 334, 336, 338, 340, and 342, a sense of depth is given to the graphic, and a three-dimensional display can be created in embodiments.

[0034] FIG. 4 discloses an alternative arrangement wherein a system of multi-layer lenses are subjected to indirect lighting. More specifically, referring to FIG. 4, it can be seen that a pair of LED rows, including upper row 402 and lower row 404, again, going into and out of the page, initially direct light into a reflector 408. Reflector 408 then directs light into a pair of lenses (in this embodiment a first lens 414, and a second lens 416) before leaving the housing.

[0035] With the FIG. 4 embodiment, like with the FIG. 3 embodiment, the inner and outer surfaces of the first lens 414 and second lens 416 have been modified by depositing a material, e.g., adding a paint, coatings, or an ink in different locations, optionally on both sides. More specifically, the lenses 414 and 416 have been inked, painted, coated, or otherwise modified in a plurality of areas, e.g., areas 418, 420,

422, 424, 426, 428, 430, 432, 434, 436, 438, 436, and 440, 442 existing on both the inside and outside of the lenses.

[0036] More specifically, the first lens 414 has an inner surface that includes four areas onto which an ink, paint, or other optically active material has been added. For example, in area 418 an opaque ink layer has been added for the purpose of blocking the emission of light therethrough. Immediately below that, in an area 420, a translucent ink has been added to modify the light, e.g., creating a desired color, decorative depiction, or other effect. A next area down 422 shows a lighter translucent ink with a color different than the one used in area 420. Immediately below that, an area 424, in the FIG. 4 embodiment is also opaque like area 418. Those skilled in the art will recognize that in embodiments, areas 418 and 424 may also be made reflective to increase light emission efficiency into the parabolic reflector 408. The opaque upper and lower coatings 418 and 424, because they block the light emitted, only allow light through the central horizontal band 420. Thus, only the translucent colored/inked area 420 allows for the passage of light. Although not evident from FIG. 4, each coated area (of occluded areas 418 and 424, and the translucent slit 420) extends into and out of the page in a uniform horizontal fashion, thus creating a single colored band of light passage at a vertical center (as seen in cross section) of the first lens 414.

[0037] On the other (outer) side of the first lens 414, paints/inks have been applied to an areas 426, 428, and 430 in order to create (in combination with the blocking coatings 418 and 424, and the translucent slit 420 applied to the inner side), a three-dimensional effect when the device is illuminated, or not illuminated (e.g., in sunlight). Again here, although not evident from FIG. 4, each coated area (of areas 426, 428, and 430) extends into and out of the page in a uniform horizontal fashion, thus creating bands of diverse paints at different levels of the first lens 414.

[0038] Across the second gap/chamber 415, the second outer lens 416 includes three similar inside application areas 431, 432, and 433, each including a similar kind of paint (alternatively ink). Bands 431 and 432 are separated by a differently painted upper band 436, and bands 432 and 433 are separated by a lower horizontal gap 440. Although these application areas 431, 432, and 433, in the disclosed embodiment, are identical or substantially similar coated stripes, those skilled in the art will recognize that each of areas 431, 432, and 433 could be painted differently depending on the desired effect. In the disclosed embodiment, the different areas have been made coated at different locations for the purpose of providing a three-dimensional layered effect, and colored appearance when being illuminated, or when not illuminated. On the outer side of lens 416, in the disclosed embodiments, three areas having different paint applications 434, 438, and 442 have been deposited, and these painted areas are spaced apart by differently painted areas 436 and 440.

[0039] It should be noted, that any of areas 418, 420, 422, 424, 426, 428, 430, 431, 432, 433, 434, 436, 438, 440, and 442 could each include any variety or combination of ink, coatings, etc. of any light modifying characteristic for the purpose of creating any three-dimensional or other desired effect. One example of a three- dimensional effect which might be advantageously created is that of a three- dimensional rendering of a logo complete with colors, graphics, indicia, and other matter.

[0040] FIG. 5 discloses an alternative arrangement wherein a system 500 includes multi-layer lenses 514 and 516 that are subjected to direct lighting by three horizontally-extending LED rows 502, 504, and 506 mounted on a common PCB 528. The rows are arranged to emit in a forward direction to illuminate lenses 514 and 516. The FIG. 5 embodiment includes substantially the same lens arrangement disclosed in FIGs. 3-4.
