Therefore, specific structural and functional details disclosed herein are not to be construed as limiting, but merely as a representative basis for teaching a person skilled in the art to employ the present disclosure in a variety of ways.

[035] As used here, the term “and / or, when used in a list of two or more items, means that any of the items listed can be used by itself, or any combination of two or more of the items listed can be employed. For example, if a composition is described as containing components A, B, and / or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.

5/35 [036] The following disclosure describes a vehicle lighting system in which a vehicle installation receives a photoluminescent structure to convert a primary emission into a secondary emission generally having a new color. For the purposes of this disclosure, a vehicle installation refers to any interior or exterior piece of vehicle equipment, or part of it, suitable for receiving the photoluminescent structure described in this document. Although the implementation of the vehicle lighting system described here is primarily intended for use in an automotive vehicle, it should be appreciated that the vehicle lighting system can also be implemented in other types of vehicles designed to carry one or more passengers, such as, for example, boats, trains and aircraft.

[037] Referring to figs. 1 and 2, a passenger compartment 10 of an automotive vehicle is generally shown having a variety of examples of vehicle installations 12a-12g located in the front and rear passenger compartment 10. Facilities 12a-12g generally correspond to a roof liner , a floor mat, a door trim panel, and various parts of a seat, including a seat base, a backrest, a headrest, and a seat back, respectively. For purposes of illustration, not limitation, each installation 12a-12g can receive a photoluminescent structure, described further below, in a selected area 14a-14f of each installation 12a-12f. With regard to the vehicle lighting system described here, it should be appreciated that the selected area 12a-12f is not limited to any particular shape or size, and may include portions of an installation having planar and / or non-planar configurations. Although some installations 12a-12g have been provided as an example, it should be appreciated that other installations can be used in accordance with the vehicle lighting system described here. These installations may include instrument panels and their components, interactive mechanisms (for example, push buttons,

6/35 switches, dialers, and the like), indicating devices (for example, speedometer, tachymeter, etc.), printed surfaces, as well as exterior installations, such as, for example, keyless entry keys, badges, side markers, license plate lamps, trunk lamps, headlights, and turn signals.

[038] Referring to figs. 3A-3C, a photoluminescent structure 16 is shown generally treated as a coating (for example, a film) capable of being applied to a vehicle installation, a discrete particle capable of being implanted in a vehicle installation, and a plurality of discrete particles embedded in a separate structure capable of being applied to a vehicle installation, respectively. At the most basic level, the photoluminescent structure 16 includes an energy conversion layer 18 that can be provided as a single layer or a multilayer structure, as shown through broken lines in figs. 3A and 3B. The energy conversion layer 18 can include one or more photoluminescent materials having energy converting elements selected from a phosphorescent material or fluorescent m, and formulated to convert a captured electromagnetic radiation into a sent electromagnetic radiation generally having a longer wavelength. and expressing a color that is not characteristic of the electromagnetic radiation captured. A difference in wavelength between the electromagnetic radiation captured and sent is referred to as the Stokes displacement and serves as the main triggering mechanism for the aforementioned energy conversion process, often referred to as downward conversion.

[039] The energy conversion layer 18 can be prepared by dispersing the photoluminescent material in a polymeric matrix to form a homogeneous mixture using a variety of methods. These methods may include preparing the energy conversion layer 18 from a formulation in a liquid carrier medium and coating the energy conversion layer 18 on a desired planar and / or non-planar substrate from

7/35 a vehicle installation. The energy conversion layer coating 18 can be deposited in the selected vehicle installation by painting, screen printing, spraying, extrusion coating, dip coating, roller coating and bar coating. Alternatively, the energy conversion layer 18 can be prepared by methods that do not use a liquid carrier medium. For example, a solid state solution (homogeneous mixture in a dry state) of one or more photoluminescent materials in a polymeric matrix can be converted to energy conversion layer 18 by extrusion, injection molding, compression molding, calendering and thermoforming. , etc. In cases where one or more energy conversion layers 18 are treated as particles, the single or multilayer energy conversion layers 18 can be implanted in the chosen vehicle installation instead of applying it as a coating. When the energy conversion layer 18 includes a multilayer formulation, each layer can be coated sequentially, or the layers can be prepared separately and then laminated or embossed together to form an integrated layer. Alternatively, the layers can be coextruded to prepare an integrated multilayer energy conversion structure.

[040] Referring back to figs. 3A and 3B, the photoluminescent structure 16 can optionally include at least one stability layer 20 to protect the photoluminescent material contained within the energy conversion layer 18 against photolytic and thermal degradation, in order to provide sustained emissions of sent electromagnetic radiation. The stability layer 20 can be configured as a separate layer and be optically coupled and adhered to the energy conversion layer 18 or otherwise integrated into the energy conversion layer 18 provided that a suitable polymer matrix is selected. The photoluminescent structure 16 can also optionally include a protective layer 22 optically coupled and adhered to the stability layer 20 or to

8/35 another layer to protect the photoluminescent structure 16 against physical and chemical damage arising from environmental exposure.

[041] The stability layer 20 and / or the protective layer 22 can be combined with the energy conversion layer 18 to form an integrated photoluminescent structure 16 through sequential coating or printing of each layer, or by sequential lamination or embossing. relief. Alternatively, several layers can be combined by sequential coating, lamination or embossing to form a substructure, and the required substructure then laminated or embossed together to form the integrated photoluminescent structure 16. Once formed, the photoluminescent structure 16 can be applied to a chosen vehicle installation. Alternatively, the photoluminescent structure 16 can be incorporated in the vehicle installation chosen as one or more discrete multilayer particles. Alternatively, further, the photoluminescent structure 16 can be supplied as one or more discrete multilayer particles dispersed in a polymer formulation which is applied subsequently to the chosen vehicle installation as a contiguous structure. Additional information regarding the construction of photoluminescent structures is disclosed in US Patent No. 8,232,533 entitled “PHOTOLITICALLY AND ENVIRONMENTALLY STABLE MULTILAYER STRUCTURE FOR HIGH EFFICIENCY ELECTROMAGNETIC ENERGY CONVERSION AND SECONDARY EMISSION, which is incorporated in this document, which is fully disclosed in this document. reference.

[042] Referring to figs. 4 and 5, a vehicle lighting system 24 is generally shown and according to a front light configuration (FIG. 4) and a rear light configuration (FIG. 5). In both configurations, the vehicle lighting system 24 includes a photoluminescent structure 16 treated as a coating and applied to a substrate 40 of a vehicle installation 42. The photoluminescent structure 16 includes an energy conversion layer 18 and optionally includes the stability layer 20

9/35 and / or the protective layer 22, as previously described. The energy conversion layer 18 includes a photoluminescent material emitting red Xi, a photoluminescent material emitting green X2, and a photoluminescent material emitting blue X3 dispersed in a polymeric matrix 44 in one embodiment. The photoluminescent materials emitting red, green and blue X1, X2, and X3 are chosen because variable mixtures of red, green and blue light will enable a variety of color sensations to be duplicated. As further described below, an excitation source 26 is operable to excite each of the red, green and blue emitting photoluminescent materials X1, X2, and X3 in various combinations to produce different colored light, which can escape from the photoluminescent structure 16 to provide ambient or task lighting.

[043] The excitation source 26 is generally shown in an external location in relation to the photoluminescent structure 16 and is operable to emit a primary emission having a light content defined by a first captured electromagnetic radiation represented as directional arrow 28, a second captured electromagnetic radiation represented as directional arrow 30, and / or a third captured electromagnetic radiation represented as directional arrow 32. The contribution of each captured electromagnetic radiation 28, 30, 32 in the primary emission depends on a state of activation of a light emitting diode (LED) configured to send light at a single peak wavelength. In both configurations, the first electromagnetic radiation captured 28 is emitted from the blue LED 34 at a peak wavelength λι selected from a blue spectral color range, which is defined as the range of wavelengths generally expressed as blue light (~ 450-495 nanometers). The second captured electromagnetic radiation 30 is emitted from the blue LED 36 at a peak wavelength λ2 also selected from the blue spectral color range and the third captured electromagnetic radiation 32 is emitted from the blue LED 38 at a wavelength of peak λ3 selected

10/35 still from the blue spectral color range.

[044] Because of the peak wavelengths λι, λ2, and λ3 having different lengths, blue LEDs 34, 36, and 38 can each be responsible for basically exciting one of the photoluminescent materials emitting red, green and blue Xi, X2, X3. Specifically, the blue LED 34 is primarily responsible for exciting the photoluminescent material emitting red X1, the blue LED 36 is primarily responsible for exciting the photoluminescent material emitting green X2, and the blue LED 38 is basically responsible for exciting the photoluminescent emitting material in blue X3. For more efficient energy conversion, the X1 red-emitting photoluminescent material is selected to have a peak absorption wavelength corresponding to the peak wavelength λι associated with the first captured electromagnetic radiation 28. When excited, the photoluminescent material red emitter X1 converts the first captured electromagnetic radiation 28 into a first sent electromagnetic radiation represented as directional arrow 46 and having a peak emission wavelength E1 that includes a red spectral color gamma wavelength, which is defined here as the range of wavelengths generally expressed as red light (~ 620-750 nanometers). Likewise, the photoluminescent green-emitting material X2 is selected to have a peak absorption wavelength corresponding to the peak wavelength À2 of the second captured electromagnetic radiation 30. When excited, the photoluminescent green-emitting material X2 converts the second electromagnetic radiation 30 in a second sent electromagnetic radiation represented as directional arrow 48 and having a peak emission wavelength E2 that includes a wavelength of a green spectral color range, which is defined here as the wavelength range usually expressed as green light (~ 526606 nanometers). Finally, the X3 blue-emitting photoluminescent material is selected to have a peak absorption wavelength

11/35 corresponding to the peak wavelength λ3 of the third captured electromagnetic radiation 32. When excited, the blue emitting photoluminescent material X3 converts the third captured electromagnetic radiation 32 into a third sent electromagnetic radiation represented as the arrow 50 and having a length peak emission wavelength E3 that includes a longer wavelength of the blue spectral color range.

[045] Considering the relatively narrow band of the blue spectral color range, it is recognized that some spectral overlap may occur between the absorption spectra of the photoluminescent materials emitting red, green and blue X1, X2, X3. This can result in the inadvertent excitation of more than one of the red, green and blue emitting photoluminescent materials X1, X2, X3 despite only one of the blue LEDs 34, 36, 38 being active, thereby producing unexpected color mixtures. Thus, when greater color separation is desired, the red, green and blue emitting photoluminescent materials X1, X2, X3 should be selected to have narrow band absorption spectra to minimize any spectral overlap between them, and the wavelengths peak λι, λ2, and λ3 should be spaced apart to allow sufficient separation between the peak absorption wavelengths of the red, green and blue emitting photoluminescent materials X1, X2, X3. In this way, depending on which of the red, green and blue emitting photoluminescent materials X1, X2, X3 are excited, a secondary emission having a more predictable light content can be produced. The secondary emission can express a variety of colors found in a typical RGB color space, including colors that are predominantly red, green, blue, or any combination of these. For example, when the blue LEDs 34, 36, and 38 are activated simultaneously, the secondary emission may contain a mixture of additive light of red, green and blue light, which is generally perceived as white light. Other color sensations found in the RGB color space can be produced by activating the blue LEDs 34, 36, and 38 in different combinations

12/35 and / or changing the output intensity associated with the blue LEDs 34, 36, 38 by current control, pulse width modulation (MLP), or by other means.

[046] With respect to the vehicle lighting system 24 arranged here according to one embodiment, the blue LEDs 34, 36 and 38 are chosen as the excitation source 26 to take advantage of the relative cost benefit attributed to them when used in vehicle lighting applications. Another advantage of using blue LEDs 34, 36, and 38 is the relatively low visibility of blue light, which can be less distracting for a vehicle driver and other occupants in cases where the primary emission needs to propagate in plan view before reaching the photoluminescent structure 16. However, it should be appreciated that the vehicle lighting system 24 can also be implemented using other lighting devices, as well as sunlight and / or ambient light. In addition, considering the range of vehicle installations capable of receiving the photoluminescent structure 16, it should also be appreciated that the location of the excitation source 26 will naturally vary depending on the constitution of a particular vehicle installation, and can be external or internal to the photoluminescent structure 16 and / or vehicle installation. It should also be appreciated that the excitation source 26 can supply the primary emission directly or indirectly to the photoluminescent structure 16. That is, the excitation source 26 can be positioned in such a way that the primary emission propagates to the photoluminescent structure 16 or it is positioned in such a way that the primary emission is distributed to the photoluminescent structure 16 via a light tube, optical device, or the like.

[047] The energy conversion process used by each of the red, green and blue emitting photoluminescent materials Xi, X2, X3 described above can be implemented in a variety of ways, considering the wide selection of available energy conversion elements. According to an implementation, the energy conversion process takes place through

13/35 a simple absorption / emission event by an energy conversion element. For example, the photoluminescent material emitting red Xi may include a phosphor showing a large Stokes displacement for absorption of the first electromagnetic radiation captured 28 and subsequently emission of the first electromagnetic radiation sent 46. Likewise, the photoluminescent material emitting green X2 also it can include a phosphor showing a large Stokes displacement for absorption of the second electromagnetic radiation captured 30 and emission of the second electromagnetic radiation sent. A benefit of using a phosphorus or other energy conversion element that exhibits a large Stokes displacement is that greater color separation can be achieved between captured electromagnetic radiation and sent electromagnetic radiation due to a reduction in the spectral overlap between absorption corresponding and emission spectra. Similarly, with a simple Stokes shift, the absorption and / or emission spectra for a given photoluminescent material are less likely to have a spectral overlap with the absorption and / or emission spectra of another photoluminescent material, thereby providing greater color separation between the selected photoluminescent materials. [048] According to another implementation, the energy conversion process occurs through an energy cascade of absorption / emission events conducted by a plurality of energy conversion elements with relatively smaller Stokes displacements. For example, the red-emitting photoluminescent material X1 may contain fluorescent inks, whereby some or all of the first captured electromagnetic radiation 28 is absorbed to emit a first intermediate electromagnetic radiation having a longer wavelength and a color that is not characteristic of the first electromagnetic radiation captured 28. The first intermediate electromagnetic radiation is then absorbed a second time to emit a second intermediate electromagnetic radiation

14/35 having a longer wavelength and a color that is not characteristic of the first intermediate electromagnetic radiation. The second intermediate electromagnetic radiation can be further converted with additional energy conversion elements showing the appropriate Stokes shifts until the desired peak emission wavelength Ei associated with the first electromagnetic radiation sent 46 is obtained. A similar energy conversion process can also be observed for the X2 green-emitting photoluminescent material. Although energy conversion processes that implement energy cascades can produce wide color spectra, increasing the number of Stokes shifts can result in less efficient downward conversions due to a greater likelihood of spectral overlap between the associated absorption and emission spectra. . In addition, when greater color separation is desired, additional consideration should be exercised, such that the absorption and / or emission spectra of a photoluminescent material have minimal overlap with the absorption and / or emission spectra of another material photoluminescent that also implements an energy cascade or some other energy conversion process.

[049] With respect to the X3 blue-emitting photoluminescent material, successive conversions of the third electromagnetic radiation captured 32 via an energy cascade are unlikely to be necessary, since the electromagnetic radiation captured 32 and the electromagnetic radiation sent 50 are both predisposed to have relatively close peak wavelengths in the blue spectral color range. Thus, the blue photofluorescent material X3 can include an energy conversion element having a small Stokes displacement. When greater color separation is desired, the blue photoluminescent material X3 must be selected with an emission spectrum with minimal spectral overlap with the absorption spectra of the red and green photoluminescent materials X1, X2. Alternatively, an ultraviolet LED can replace blue LED 38 for

15/35 make it possible for an energy conversion element to have a greater Stokes offset to be used and to provide more flexible spacing opportunities for the emission spectrum of the X3 blue-emitting photoluminescent material within the blue spectral color range. For front light configuration, the photoluminescent structure 16 can alternatively include a narrow band reflective material configured to reflect the third captured electromagnetic radiation 32 emitted from the blue LED 38 instead of carrying out an energy conversion on it to express the blue light , which avoids the need to include the X3 blue-emitting photoluminescent material. Alternatively, the aforementioned reflective material may be configured to reflect a selected amount of the first and second captured electromagnetic radiation 28, 30 to express blue light, thereby avoiding the need to include the blue emitting photoluminescent material X3 and the blue LED 38. For backlight configurations, blue light can be expressed alternatively simply by relying on some amount of the third captured electromagnetic radiation 32 passing through the photoluminescent structure 16, in which the blue emitting photoluminescent material X3 has been omitted.

[050] Since many energy conversion elements are Lambertian emitters, the resulting secondary emissions can be propagated in all directions, including directions pointing away from a desired exit surface 52 of the photoluminescent structure 16. As a result, some or all secondary emissions can be confined (total internal reflection) or absorbed by corresponding structures (eg vehicle installation 42), thereby reducing the luminosity of the photoluminescent structure 16. To minimize the aforementioned phenomenon, the photoluminescent structure 16 can include optionally at least one wavelength selector layer 54 formulated to redirect (for example, reflect) secondary emissions propagating inordinately to the outlet surface 52, which also behaves like a surface

16/35 of input 56 with respect to the front light configuration shown in fig. 4. In cases where the input surface 56 and the output surface 52 are different, as generally shown by the rear light configuration of fig. 5, the wavelength selector layer 54 must readily transmit any primary emissions and redirect any secondary emissions by propagating inordinately to the outlet surface 52.

[051] In both configurations, the wavelength selector layer 54 is positioned between substrate 40 and energy conversion layer 18, so that at least some secondary emissions that propagate to substrate 40 are redirected to the outlet surface 52 to maximize the output of the secondary emission from the photoluminescent structure 16. For this purpose, the wavelength selector layer 54 must be prepared from a minimum of spreading materials, but do not absorb the peak emission wavelengths Hey, E2, E3 associated with the first, second and third electromagnetic radiation sent 46, 48, 50, respectively. The wavelength selector layer 54 can be treated as a coating and is optically coupled to the energy conversion layer 18 and adhered to both the energy conversion layer 18 and the substrate 40 using any of the methods described above, or other suitable methods .

[052] Referring to fig. 6, the excitation source 26 can be electrically coupled to a processor 60, which supplies power to the excitation source 26 via a power source 62 (for example, a power supply on board the vehicle) and controls the operational state of the source excitation level and / or intensity levels of the primary emission of the excitation source 26. The control instructions for processor 60 can be executed automatically from a program stored in memory. In addition or alternatively, the control instructions can be provided from a vehicle device or system via at least one input 64. Additionally or alternatively, the instructions for

17/35 control can be provided to processor 60 via any conventional user input mechanism 66, such as, for example, push buttons, switches, touch screens, and the like. Although processor 60 is shown electrically coupled to an excitation source 26 in fig. 6, it should be appreciated that processor 60 may also be configured to control sources of additional excitation using any of the methods described above.

[053] Various vehicle lighting systems will now be described in more detail. As described below, each system uses one or more photoluminescent structures in conjunction with a vehicle installation to provide a greater viewing experience for the occupants of a vehicle.

[054] REAR LIGHT SET [055] Referring to figs. 7 and 8, a tail light assembly 67 is generally shown and will be described here as incorporating the vehicle lighting system 24 in a tail light configuration described above with reference to fig. 5, and can employ any alternative configurations associated with it. As shown in fig. 7, the rear light assembly 67 is provided by way of example as a center console having a support member 68 (for example, a trim plate) supporting one or more interactive rear light members, indicated by reference numbers 70a , 70b, and 70c. For purposes of illustration, the interactive rear light members 70a, 70b, 70c are incorporated as a push button, a rotary button, and a selector switch, respectively, each configurable to enable a user to interface with one or more features vehicle, such as an audio system, a climate control system, a navigation system, etc.

[056] Referring to fig. 8, a cross-sectional view of the interactive taillight member 70a is shown according to one embodiment. With respect to the illustrated embodiment, the interactive taillight member 70a extends at least partially through an opening formed in the

18/35 support member 68 and can be mounted on the rear light assembly 67 in any conventional manner. The interactive rear light member 70a can include a light-conducting body having a front side 78 and at least one side wall 80, and can be formed by injection molding or other suitable methods. Although the interactive taillight member 70a is incorporated as a push button in fig. 8, it should be appreciated that other embodiments are also possible, such as a rotary key, a selector switch, or the like.

[057] According to the present embodiment, the excitation source 26 is positioned to provide a primary emission in the form of backlight, as represented by the directional arrow 84 for the interactive backlight member 70a. Primary emission 84 can be delivered directly from excitation source 26 or indirectly via a light tube, optical device, or the like, and can contain one or more captured electromagnetic radiation, each having a unique associated wavelength and each one being emitted from a corresponding LED.

[058] Primary emission 84 is fed to the front side 78 of the interactive rear light member 70a and is transmitted through it. The primary emission 84 is then received in the photoluminescent structure 16, which can substantially convert the entire primary emission into a secondary emission containing one or more sent electromagnetic radiation, each having a uniquely associated peak emission wavelength. Alternatively, the photoluminescent structure 16 can convert some of the primary emission to the secondary emission and transmit the rest as an unconverted sent electromagnetic radiation. In any case, one or more sent electromagnetic radiation, represented collectively by the arrow 86, exits through the exit surface 52 of the photoluminescent structure 16 and expresses a color sensation found in the RGB color space.

[059] To intensify the luminosity of the photoluminescent structure 16,

19/35 a wavelength selector layer 54 can be provided therein to redirect any backscattered secondary emissions 86 to the output surface 52. Optionally, an opaque layer 88 is coupled at least to the photoluminescent structure 16 and defines an aperture 90 which is characteristic of a badge through which the secondary emission 86 is transmitted and thereby illuminating the badge.

[060] SUMMIT LIGHTING SYSTEM FOR VEHICLE [061] Referring to fig. 9, a schematic diagram is shown to implement a dome lighting system for vehicle 92 in a vehicle 93. The dome lighting system for vehicle 92 incorporates vehicle lighting system 24 in a front light configuration, as previously described with reference to fig. 4, and can employ any alternative configurations associated with it. As shown in fig. 9, the photoluminescent structure 16 is continuously coupled to a vehicle roof liner 94, and each of a plurality of excitation sources 26a-26g are positioned to emit a primary emission for an associated area 96a-96g of the photoluminescent structure 16. The primary emission emitted from any given excitation source 26a-26g can contain one or more captured electromagnetic radiation, each having a unique associated wavelength and each being emitted from a corresponding LED. As previously described, the photoluminescent structure 16 can substantially convert the entire primary emission to a secondary emission containing one or more sent electromagnetic radiation, each having a unique associated peak emission wavelength. Alternatively, the photoluminescent structure 16 can reflect some of the primary emission and convert the remainder to the secondary emission. In either configuration, the photoluminescent structure 16 can optionally include the wavelength selector layer 54 to redirect any back-cast secondary emission in order to enhance the luminosity of the photoluminescent structure 16.

20/35 [062] In the illustrated embodiment, each of the excitation sources 26a26d are operatively coupled to an associated head rest 98a98d and optically configured to illuminate a corresponding corner area 96a-96d of the photoluminescent structure 16 in a generally circular pattern. Each of the excitation sources 26e and 26f are optically coupled to an associated b-column 100e, 100f and are optically configured to illuminate a corresponding side area 96e, 96f of the photoluminescent structure 16 in a generally semicircular pattern. Finally, the excitation source 26g is operatively coupled to the roof lining of vehicle 94 and optically configured to illuminate a corresponding central area 96g in a generally circular pattern. As can be seen in fig. 9, this type of arrangement provides the opportunity for overlap between the associated areas 96a-96g which are adjacent to each other, thereby covering a substantial total area of the photoluminescent structure 16. As such, the dome lighting system for vehicle 92 can be controlled (for example, via processor 60) to provide a total or isolated lighting experience by activating all or some of the 26a-26g excitation sources. Additionally or Alternatively, the use of multiple sources of excitation 26a-26g, allows any given area 96a-96g of the photoluminescent structure 16 to produce a color sensation (composed of sent electromagnetic radiation and / or reflected captured electromagnetic radiation) found in a RGB color space that is similar to or different from the color sensation produced by any other associated area 96a-96g. This can be achieved by manipulating the light content of the primary emission emitted from any active excitation source 26a-26g.

[063] VEHICLE READING LAMP [064] Referring to fig. 10, the vehicle front passenger compartment 102 of a wheeled vehicle 104 is generally illustrated having at least one reading lamp 106 mounted on a suspended console 108. In the illustrated embodiment, suspended console 108 is mounted on the inner side

21/35 of the ceiling lining of the front passenger compartment of vehicle 102 and is positioned centrally in the front passenger compartment of vehicle 102. As shown by way of example, two reading lamps 106 are mounted on the suspended console 108, one positioned to provide greater access and lighting to a driver of vehicle 104 and the other positioned to provide greater access and lighting to a vehicle front passenger seat occupant. Each reading lamp 106 has a visible external lens and can be activated by a switch, such as a proximity switch having a proximity sensor (for example, capacitive sensor), a mechanically compressible finger key, or other means, to provide illumination task, particularly in low light or dark conditions. Although two reading lamps 106 have generally been shown in fig. 10, it should be appreciated that one or more reading lamps 106 may be mounted at other locations on the suspended console 108 or at other locations on board vehicle 104.

[065] Referring to figs. 11 and 12, a reading lamp 106 is shown according to an embodiment. As best shown in fig. 11, the reading lamp 106 includes an external lens 110 and a first surface 112 and a second surface 114 positioned behind the external lens 110. A first photoluminescent structure 116 is coupled to the first surface 112 and a second photoluminescent structure 118 is coupled to the second surface 114. A first light source 120 is provided to excite the first photoluminescent structure 116 so as to emit a first colored light to illuminate the external lens 110, and a second light source 122 is provided to excite the second photoluminescent structure 118 of in order to emit a second colored light to illuminate external lens 110. Illuminated external lens 110 can direct light illumination at an outlet to serve as a light for map reading or general reading.

[066] Each of the first and second photoluminescent structures 116,

22/35

118 can be coupled to the corresponding first and second surfaces 112, 114 in a suitable manner. The first light source 120 can be attached to the first surface 112 and the second light source 122 can be attached to the second surface 114. As best shown in fig. 12, each of the first and second light sources 120, 122 can be located peripherally on the corresponding first and second surfaces 112, 114. Additionally, each of the first and second light sources 120, 122 can be configured as side-emitting LEDs, such that light sent from the first light source 120 is projected only on the first photoluminescent structure 116 and light sent from the second light source 122 is projected only on the second photoluminescent structure 118. In one embodiment, the first and second light sources 120 , 122 are each either a blue LED or an ultraviolet LED and the first photoluminescent structure 116 contains a red emitting photoluminescent material and the second photoluminescent structure 118 contains a green emitting photoluminescent material. [067] Referring further to the embodiment shown in figs. 11 and 12, the first and second surfaces 112, 114 can be arranged opposite each other, and each of them is oriented at an acute angle in relation to the external lens 110. The first surface 112 can be configured to redirect back-cast light that originates from the first photoluminescent structure 116 to the external lens 110, and the second surface 114 can be configured to redirect back-scattered light that originates from the second photoluminescent structure 118 to the external lens 110. With respect to the present embodiment, each of the first and second surfaces 112, 114 can be a surface of a corresponding printed circuit board (PCI) 124, 126 that has a reflective coating, such as a white solder mask or insulating coating to redirect backscattered light that originates from the first and second structures corresponding photoluminescent 116, 118 for external lens 110.

[068] As shown in Figs. 11 and 12, the reading lamp

23/35

106 may also include a third light source 128 positioned between the first and second surfaces 112, 114 and disposed on a third surface 130, which may be that of a corresponding PCI 132 or other support structure. In addition, the third light source 128 can be an LED (for example, blue LED) oriented to directly illuminate the external lens 110. In this way, when the light sources 120, 122, and 128 are activated, the external lens 110 can be illuminated simultaneously with light sent from the first photoluminescent structure 116, the second photoluminescent structure 118, and the third light source 128. In one embodiment, the external lens 110 can be an optical diffuser configured to disperse light received from the first, second and / or third light sources 120, 122, 128, so that the light that leaves the external lens 110 is more evenly distributed. Additionally, PCIs 124, 126, 132 can be supported within a housing 133 which is coupled to the external lens 110.

[069] In operation, the activation status of each light source 120, 122, 128 can be controlled independently by a processor (for example, processor 60). In this way, one or more light sources 120, 122, 128 can be activated, so that different colors of visible light can be emitted from the external lens 110 and observed by the occupants of the vehicle. For example, in the embodiment where the first and second photoluminescent structures 116, 118 are red and green emitting structures, respectively, and the light source 128 is a blue LED, it is possible to produce several colored lights in the RGB color space. This can be done by selecting which of the light sources 120, 122, 128 to activate, as well as adjusting the amount of electrical energy fed into them via pulse width modulation (MLP) or direct current control. It is considered that the wavelength or color of light sent from the lens can be set automatically or by a vehicle occupant through a user input mechanism (for example, the user input mechanism 66).

[070] VEHICLE VEHICLE

24/35 [071] Referring to figs. 13-15, a vehicle lighting system 134 is illustrated according to one embodiment. System 134 includes a sun visor 136 having a sun visor body 138 that is movable between a guarded position (FIG. 14) and a wearable position (FIG. 15). In the illustrated embodiment, a sun visor 136 is mounted on a vehicle roof structure 140 and generally abuts against it in the guarded position and suspends downwards from it in the use position to block sunlight and thereby prevent a vehicle occupant 142 be dazzled. In addition, the sunshade body 138 may include a make-up mirror 144, as well as other accessories commonly associated with sunshades.

[072] With respect to the illustrated embodiment, a photoluminescent structure 146 is coupled to a surface 148 of the sun visor body 138 which is generally facing the occupant of the vehicle 142 when the sun visor body 138 is moved to the use position. As best shown in fig. 13, the photoluminescent structure 146 can be applied to a substantial portion of the unoccupied space of the surface 148. However, it should be appreciated that the photoluminescent structure 146 can occupy a smaller portion of the surface 148, if desired. In addition, the portions of the photoluminescent structure 146 may be hidden to display an insignia.

[073] Referring further to figs. 13-15, a light source 150 is located remotely from the sunshade body 138. As shown, the light source 150 can be coupled to the ceiling structure 140 and oriented to excite the photoluminescent structure 146 when the breaking body -sun 138 is in the use position. In addition, the light source 150 can be submerged in the ceiling structure 140 to remain hidden from view and can be energized via the power source 151 (e.g., on-board power supply). In this way, the photoluminescent structure 146 and the light source 150 can be used together as a make-up light and allows a sun shade 136 to be built free of any electrical components and wiring, thereby providing a simpler and more cost-effective design

25/35 benefit. In addition, due to the positioning of the light source 150, the light emitted from it that is reflected off the sun visor body 138 is unlikely to penetrate the vehicle occupant's field of view. 142. With regard to the vehicle lighting system 134 described and shown here, it should be understood that the light source 150 and the photoluminescent structure 146 can assume any of the front light configurations described hereinabove. That is, the light source 150 can include one or more LEDs and the photoluminescent structure 146 can include one or more photoluminescent materials formulated to convert light received from a corresponding LED into visible light of a different wavelength.

[074] As shown in Figs. 13-15, vehicle lighting system 134 may include a proximity switch or proximity sensor 152 for activating the light source 150 in response to a signal change. The proximity sensor 152 can be magnetic, capacitive, infrared, or the like, and combinations thereof. Additionally or Alternatively, the light source 150 can be activated via a mechanical switch.

[075] In the illustrated embodiment, the proximity sensor 152 is configured to detect the sun shade body 138 in the stored position and activate the light source 150 when the sun shade body 138 is no longer detected. The proximity sensor 152 is shown as a magnetic switch embedded in the roof structure 140 which is driven by a magnet 154 embedded in the sun visor body 138. The magnet 154 can be located at one end of the sun visor body 138 and aligns with the magnetic switch when the sun visor body 138 is in the stored position. In this position, magnet 154 applies a magnetic field to the magnetic switch that causes a pair of contacts 156, 158 to open and thereby deactivate the light source 150. Alternatively, when the sun visor body 138 is moved to the use position, the magnetic field is no longer present and the contacts 156, 158 are returned to a closed position,

26/35 light source 150 be activated and excite the photoluminescent structure 146 by activating the light source 150.

[076] Therefore, a photoluminescent structure and various vehicle lighting systems employing it have been provided here. Each system advantageously employs one or more photoluminescent structures to improve a driving experience and / or the overall appearance of a vehicle installation.

[077] HIDDEN VEHICLE SWITCHES [078] Referring to figs. 16-17, a vehicle system 166 is illustrated incorporating a user interface 168 which may be in the form of a hidden user interface. User interface 168 may be incorporated into the sun visor body 138 of a sun visor 136. Similar to system 134, the photoluminescent structure 146 or a first photoluminescent portion 172 may be coupled to the surface 148 of the sun visor body 138. A first light source 174, configured similarly to the light source 150, can be located remotely in relation to the sun shade body 138. When activated, for example, in response to magnet 154 by activating magnetic sensor 152, the first light source 174 is configured to emit a first light emission 176. The first emission 176 can excite the first photoluminescent portion 172 to illuminate the photoluminescent structure 146.

[079] The first emission 176 can comprise a first wavelength λι of directed light from the first light source 174. The first wavelength λι can be configured to achieve a first absorption spectrum of the first photoluminescent portion 172. In response upon receipt of the first emission 176, the first photoluminescent portion 172 may become excited and light up by emitting a second emission 178 having a second wavelength λ2. The second emission 178 is represented by the surface pattern of diagonal bands on the surface 148. The second wavelength À2 may be longer than

27/35 the first wavelength λι and correspond to a color of light that is more precisely perceptible in the visible light spectrum than the first wavelength λι.

[080] In an example implementation, the first light source 174 comprises an LED configured to emit the first wavelength λι which corresponds to a blue spectral color range. The blue spectral color range comprises a range of wavelengths generally expressed as blue light (~ 440-500 nm). In some implementations, the first λι wavelength can also comprise wavelengths in a color range close to ultraviolet (~ 390-450 nm). In an example implementation, λι can be approximately equal to 470 nm. In some implementations, the first wavelength λι can be approximately less than 500 nm, such that the first wavelength λι of light is not significantly visible in relation to the second wavelength λ2.

[081] The second wavelength λ2 may correspond to a warmer color having a longer wavelength (s) than the substantially projected blue light from the first light source 174. As such, the first projected emission 176 from the first source of light 174 may be substantially less visually apparent than the second emission emitted from the first photoluminescent portion 172. For example, the first photoluminescent portion 172 may appear to illuminate directly from the surface 148, while the external light source (for example, the first light source 174) goes unnoticed due to the limited visibility of the first wavelength λι. In this way, the disclosure can provide light to be generated by the photoluminescent portions in remote locations in relation to at least one external light source.

[082] Vehicle system 166 may further comprise at least one proximity sensor 180 which can be operable to trigger a control output. In some implementations, said at least one sensor of

28/35 proximity can comprise a plurality of proximity sensors 182. The plurality of proximity sensors 182 are designated as a first sensor S1, a second sensor S2, a third sensor S3, and a fourth sensor S4. Each of the sensors can be configured to control at least one control output corresponding to a system or device of the vehicle 104. In some implementations, proximity sensors 182 can be implemented as capacitive sensors. However, it should be appreciated by those skilled in the art that other types of proximity sensors can be used in addition to and / or alternatively to capacitive sensors. Proximity sensors 182 may include, for example, magnetic sensors, inductive sensors, optical sensors, resistive sensors, temperature sensors, and the like, or any combination thereof.

[083] As shown in fig. 16, each of the plurality of sensors 182 is shown as having a contour, such that user interface 168 is visually apparent, such that an operator can locate each of the sensors 182 and identify a function of an output corresponding control. For example, a location for each of the S1-S4 sensors can be indicated by a 184 symbol or icon to identify a location and function for each sensor. In a unique and new configuration, each of the symbols 184, are configured to selectively define the sensors S1-S4 that may be included in the shade body 138 as a second photoluminescent portion 186. In this configuration, the symbols 184 are configured to selectively identify the locations of the S1-S4 sensors in response to a third projected emission 188 from a second light source 190.

[084] For example, in response to the third emission 188 being inactive, the sun visor body 138 may appear as shown in fig. 13. That is, the symbols 184 provided to locate the plurality of sensors 182 may not be visibly apparent or identified by any markings

29/35 as shown in fig. 13. In response to the second light source 190 being activated, the third emission 188 can be projected onto the second photoluminescent portion 186. In response to receiving the third emission, the second photoluminescent portion 186 can convert the third emission 188 into a fourth emission 189. The fourth emission 189 can correspond to ambient lighting or luminescent portion of the symbols 184. The fourth emission 189 can reveal the symbols 184 and reveal a location of the S1-S4 sensors, such that an operator can identify a location and / or a function for each of the S1-S4 sensors.

[085] The third emission 188 may comprise a third wavelength λ3 of light directed from the second source 190. The third wavelength À3 may be configured to achieve a second absorption spectrum of the second photoluminescent portion 186. In response to receipt of the third emission 188, the second photoluminescent portion 186 can become excited and light up by emitting the fourth emission 189 having a fourth wavelength À4.

[086] Similarly to the first λι wavelength, the third λ3 wavelength can be approximately less than 500 nm in the blue or near ultraviolet light range. In some implementations, the third wavelength λ3 may correspond to a wavelength different from the first wavelength λι. In this configuration, the first light source 174 and the second light source 190 can be configured to selectively illuminate the first photoluminescent portion 172 and the second photoluminescent portion 186 independently.

[087] For example, the third wavelength λ3 may be configured to achieve the second absorption spectrum of the second photoluminescent portion 186 which may be substantially different from the first absorption spectrum of the first photoluminescent portion 172. The first absorption spectrum may have a first absorption range of approximately 465 nm to 510 nm of light that will excite or activate the first

30/35 photoluminescent portion 172. The second absorption spectrum may have a second absorption range of approximately 415 nm to 460 nm of light that will activate the second photoluminescent portion 186. In this configuration, the first light source 174 can illuminate the first photoluminescent portion 172 by selectively projecting the first emission 176. The second light source 190 can also illuminate the second photoluminescent portion 186 by selectively projecting the third emission 188. In addition, the first photoluminescent portion 172 and the second photoluminescent portion 186 can be selectively illuminated independently or in combination by activating one or both of the light sources 174, 190.

[088] The photoluminescent portions 172, 186 discussed here are referred to as the first and second photoluminescent portions for reasons of clarity. Each of the photoluminescent portions 172, 186 can be incorporated into various implementations of the disclosure alone or in combination. In some implementations the user interface 168 can be located close to or in a remote location in relation to the sunburn 136 and the makeup light or the first photoluminescent portion 172. As such, the user interface 168 can be located at various locations on the vehicle 93, for example, a roof lining, vehicle column, console, etc. [089] In order to provide the symbols 184 by locating the sensors S1-S4 to be visible when both the first photoluminescent portion 172 and the second photoluminescent portion 186 are illuminated, the second emission 178 and the fourth emission 189 can correspond to different colors. For example, the second emission 178 may correspond to a combination of wavelengths configured to illuminate the first photoluminescent portion 172 in a light substantially white in color. The fourth emission 189 can correspond to a wavelength in the red / orange color range, approximately 620 nm to 730 nm, such that the fourth emission from the second photoluminescent portion 186 is visually apparent when the second emission and the fourth emission They are

31/35 active. In this configuration, the first and second photoluminescent portions 172, 186 can be used in a sun visor 136 or any other vehicle panel in an overlapped configuration to provide selective lighting for each of the photoluminescent portions 172, 186 alone or in combination.

[090] In order to provide the hidden user interface 168, the S1S4 sensors can be hidden behind an outer layer arranged over the S1-S4 sensors. The outer layer can comprise any form of material including fabrics, coatings, and textiles of organic and / or inorganic materials. For example, materials can include polymeric materials, various fibers, and any form of material configured to allow proximity sensors S1-S4 to detect proximity through them.

[091] A light output color generated by the photoluminescent material for the second emission 178 or the fourth emission 189 can correspond to a wide variety of light colors. In order to generate the second and fourth emissions 178, 189, the energy conversion layer 18 may comprise any combination of red-emitting photoluminescent material, green-emitting photoluminescent material, and blue-emitting photoluminescent materials. The photoluminescent materials emitting red, green and blue can be combined to generate a wide variety of light for the second emission 178 and the fourth emission 189. For example, the photoluminescent materials emitting red, green and blue can be used in a variety proportions and combinations to control the output color of the second issue 178 and / or the fourth issue 189.

[092] Referring now to fig. 17, a schematic diagram of the vehicle lighting system 170 is shown demonstrating proximity detection. As discussed with reference to figs. 14-16, the first light source 172 and / or the light source 150 can be selectively activated via magnetic sensor 152 to emit the first emission 176. The second light source 190 can be selectively activated in response to sensors 182 that detect

32/35 an object 202 in a first proximity 204. In response to detection of object 202 in the first proximity 204, at least one of the sensors 182 can send a signal to a controller 206 to activate the second light source 190 to send the third emission 188. In response to receiving the third emission 188, the second photoluminescent portion 186 can become illuminated and emit the fourth emission 189. Controller 206 can correspond to any analog and / or digital circuitry (for example, a processor, controller, microcontroller, etc.), [093] In some implementations, controller 206 may be in communication with magnetic sensor 152, the plurality of sensors 182, and each of the light sources 174, 190. In this configuration, controller 206 may be configured to control the activation of each of the light sources 174, 190 in response to various signals received from the plurality of sensors 182 and the magnetic sensor. 152. Controller 206 may also be configured to control output signal output corresponding to the signals and control output of each of the S1-S4 sensors via control output 208. Control output 208 can communicate the output signals of control to control one or more vehicle systems or devices. In this way, controller 206 is operable to receive inputs from sensors 182 to control a variety of devices and systems in a vehicle. [094] Controller 206 can selectively activate the second light source 190 in response to the object 202 being detected at the first proximity 204 upon receipt of a signal that exceeds a first threshold. Proximity as discussed here can be defined as a predetermined distance or distance which in some implementations may correspond to a signal or value output by a proximity sensor in response to object 202 located at the predetermined distance. For example, as object 202 approaches the plurality of sensors 182, a sensor signal communicated from at least one of sensors 182 to controller 206 may increase. Once the sensor signal exceeds the first threshold, the object

33/35

202 is determined to be within the first proximity 204 of at least one of the sensors 182. In response to the sensor signal exceeding the first threshold, the controller can selectively activate the second light source 190, such that the second photoluminescent portion 186 becomes enlightened. With the second photoluminescent portion 186 illuminated, a user can identify a location for each of the sensors 182 by viewing the symbol 184 or icon.

[095] Controller 206 may also be configured to identify a control input in response to object 202 being detected at a second proximity 210 for each of the S1-S4 sensors. For example, once the second photoluminescent portion 186 is illuminated, the user can identify a control output corresponding to one of the S1S4 sensors. In response to identifying a location of a desired output control and a corresponding sensor (eg, S1), the user can move closer in proximity to the first S1 sensor. Once the user (e.g., object 202) moves within the second proximity 210, a first sensor signal output from the first sensor S1 may exceed a second threshold. In response to the first sensor signal exceeding the second threshold, controller 206 may send a control signal via control output 208 to control a particular vehicle system or device.

[096] Each of the S1-S4 sensors can be configured to communicate a sensor signal that can identify a specific sensor (for example, S1) and have controller 206 send a corresponding control output to control a device, system or function particular. The various implementations discussed here can provide a user interface 168 that is selectively revealed in response to the presence of an object 202 being detected by at least one sensor 180. In some implementations, object 202 may correspond to a hand or finger and may also match any type of object that can be detected by

34/35 said at least one sensor 180. The disclosure provides several systems that can be applied flexibly in a variety of environments and locations in a vehicle to provide the 168 user interface.

[097] A control output as described here can include control of multiple vehicle systems in response to an input at the second proximity 208. For example, a control output can be communicated from the controller to a vehicle system or devices configured for control or select an electric window or door lock, child safety locks, electric window locks, heating / cooling operations, a sensor or light activation, etc. A control output can comprise any form of signal that can be configured to control a vehicle system or device. In some implementations, controller 206 may also be configured to selectively activate and deactivate the first light source 174. As discussed here, the term threshold can refer to any identifiable characteristic of a signal received by at least one of the S1- sensors. S4, for example a digital signal value, analog signal level, voltage, current, etc. In response to object 202 located within each of the thresholds (for example, the first threshold and the second threshold) sensors 182 can send signals corresponding to a variety of ranges and thresholds that can vary based on a particular sensor used in an application particular.

[098] Although system 170 is discussed in detail with reference to sunshade 136, system 170 including the hidden user interface 168 can be implemented on a plurality of vehicle panels according to the disclosure. In addition, the 168 user interface can be used in a variety of applications incorporating any number of inputs.

[099] It is to be understood that variations and modifications can be made in the aforementioned structure without departing from the spirit of the present disclosure, and furthermore, it is to be understood that these concepts are

35/35 intended to be covered by the following claims, unless these claims by their languages expressly state otherwise.
