The badge may advantageously use one or more multicolor light sources configured to illuminate in multiple colors at predefined frequencies. The badge may further include one or more photoluminescent structures configured to convert light received from an associated light source and to re-emit the light at a different wavelength, which is typically found in the visible spectrum.
  • Regarding 1A - 1C are different embodiments of photoluminescent structures 10 each of which is capable of having a substrate 12 coupled, which may be a vehicle trim part or a vehicle-related piece of equipment. at 1A becomes the photoluminescent structure 10 generally shown as a coating (eg, as a film) formed on a surface of the substrate 12 can be applied. In 1B is the photoluminescent structure 10 generally shown as a discrete particle capable of being in a substrate 12 to be integrated. In 1C is the photoluminescent structure 10 generally shown as multiple discrete particles contained in a carrier medium 14 (eg a film) can be integrated, which then on the substrate 12 applied (as shown) or can be integrated therein.
  • At the most elementary level involves a given photoluminescent structure 10 an energy conversion layer 16 , which may include one or more sublayers exemplified by the dashed lines in FIG 1A and 1B are shown. Each sub-layer of the energy conversion layer 16 may include one or more photoluminescent materials having energy conversion elements with phosphorescent or fluorescent properties. Each photoluminescent material can be excited upon receiving light having a specific wavelength, whereby the light undergoes a conversion process. Under the principle of downconversion, the coupled light is converted to light of a longer wavelength, that of the photoluminescent structure 10 is decoupled. Conversely, under the principle of upconversion, the coupled light is converted to light having a shorter wavelength, that of the photoluminescent structure 10 is decoupled. When from the photoluminescent structure 10 several different wavelengths of light are coupled out at the same time, these wavelengths of light can mix together and appear as multicolored light.
  • In some embodiments, light that has been downconverted or upconverted may be used to excite one or more other photoluminescent materials included in the energy conversion layer 16 are to be used. The process of using converted light that is coupled out of one photoluminescent material to excite another, etc., is commonly referred to as an energy cascade and may serve as an alternative to achieving different hues. In terms of both conversion principles, the wavelength difference between the exciting light and the converted light is referred to as Stokes shift and serves as the basic driving mechanism for a power conversion process corresponding to a light wavelength change. In the various implementations discussed herein, each of the photoluminescent structures may operate under one of the conversion principles.
  • The energy conversion layer 16 can be prepared by using the photoluminescent material using different Process is dispersed in a polymer matrix to form a homogeneous mixture. Such methods may include preparing the energy conversion layer 16 from a formulation in a liquid carrier medium and applying the energy conversion layer 16 to a desired substrate. The energy conversion layer 16 can be applied by means of painting, screen printing, spraying, die coating, dip coating, roller application and comma coating. Alternatively, the energy conversion layer 16 produced by processes that do not use a liquid carrier medium. For example, the energy conversion layer 16 by dispersing the photoluminescent material into a solid solution (homogeneous mixture in a dry state) which may be integrated into a polymer matrix which may be formed by extrusion molding, injection molding, compression molding, calendering and thermoforming, etc. The energy conversion layer 16 may then be integrated into a substrate by any method known to those skilled in the art. When the energy conversion layer 16 Partial layers, each sub-layer can be applied sequentially to the energy conversion layer 16 train. Alternatively, the sublayers may be made separately and later to form the energy conversion layer 16 laminated or embossed. As a further alternative, the energy conversion layer 15 be formed by coextruding the partial layers.
  • Again referring to 1A and 1B can the photoluminescent structure 10 if desired, at least one stability layer 18 to protect the photoluminescent material inside the energy conversion layer 16 contained before photolytic and heat degradation. The stability layer 18 may be configured as a separate layer that is optically associated with the energy conversion layer 16 is coupled. Alternatively, the stability layer 18 in the energy conversion layer 16 be integrated. The photoluminescent structure 10 can also optionally a protective layer 20 having the optical with the stability layer 18 or another layer (eg, the conversion layer 16 in the absence of the stability layer 18 ) and adhesively bonded to the photoluminescent structure 10 to protect against physical and chemical damage due to environmental exposure. The stability layer 18 and / or the protective layer 20 can with the energy conversion layer 16 by sequential application or printing of each layer, sequential lamination or embossing, or other suitable means.

  • Regarding 2 is generally a plaque 22 shown at a front end 24 of a vehicle 26 is attached. In other embodiments, the badge may 22 located elsewhere, such as at the rear end or at the sides of the vehicle, among other things 26 , The badge 22 may be configured as an insignia, which is displayed as an identification mark of a vehicle manufacturer and a visible part 28 includes, generally on the vehicle 26 is conspicuous. In the present illustrated embodiment, the badge is located 22 near a radiator grill arrangement 30 at a central location of the front end 24 , causing the badge 22 from an observer looking directly at the vehicle 26 looks, easy to see. As will be described in more detail below, the badge may 22 shine and flashing (ie bright, with flashing lights in several colors) to the vehicle 26 with a noticeable styling element.
  • Regarding 3 is an example of the visible part 28 the badge 22 according to one embodiment. The visible part 28 can be a transparent and / or translucent part 32 and substantially opaque parts 34 which may be configured as opaque coatings on the visible part 28 be applied. In alternative embodiments, the parts 34 to the front end 24 of the vehicle 26 be left open. The visible part 28 can also be a photoluminescent part 36 (please refer 4 ), which is connected to the underside of the visible part 28 coupled and configured in response to the excitation by light from one or more light sources 38 is emitted, located within the plaque 22 located underneath the photoluminescent part 36 are positioned to luminesce. The light sources 38 may be configured as light-emitting diodes (LEDs) emitting a wavelength of light characterized as ultraviolet light (~ 10-400 nm wavelength), violet light (~ 380-450 nm wavelength), or blue light (~ 450-495 nm wavelength) to capitalize on the relatively low costs associated with these types of LEDs.
  • According to one embodiment, light sources 38 emitted light through the photoluminescent part 36 converted into light with a longer wavelength and output from it. The converted light corresponds to visible light which comprises the part of the electromagnetic spectrum which can be detected by the human eye (~ 390-700 nm wavelength) and in different colors, defined by a single wavelength (eg red, green, blue) or a mixture of multiple wavelengths (eg, white). Thus, it is understood that the photoluminescent part 36 may be configured such that converted light outputted therefrom can be expressed as monochrome or multicolor light. According to one embodiment, light sources 38 configured to emit blue light, and the photoluminescent portion 36 is configured to convert the blue light to a neutral white light with a color temperature of about 4000K to 5000K. The converted light escapes from the badge 22 by means of the part 32 , causing the part 32 enlightened. To ensure even illumination of the part 32 You can get the light sources 38 be configured to emit unfocused light, and are accordingly within the badge 22 for providing a uniform distribution of light for exciting the photoluminescent part 36 spaced.
  • In addition to lighting the part can 32 be configured to fade in one or more places, as in 3 graphically represented by stars. The locations can be selected to fit a corner or edge of the part 32 correspond. The blinking effect at that point can be generated by light coming from a corresponding light source 42 is emitted, located within the plaque 22 located and under the photoluminescent part 36 is positioned in relative proximity to the Aufblinkstelle. Every light source 42 can be operated so that it emits light pulses to the appropriate Aufblinkstelle. According to one implementation, a light pulse from a given light source 42 about 1/10 to 1/100 of a second and the light sources last 42 can be output at random or in a pattern pulsewise. In addition, every light source can 42 a variable current is supplied to adjust the luminous level for each flashing. For example, the current can vary from 1 to 5 times the quiescent current. In addition, each in the plaque 22 arranged light source 42 in several colors, as described in more detail below.
  • The light sources 42 may be configured as LEDs that emit a wavelength of light that is the photoluminescent portion 36 does not stimulate and instead through the photoluminescent part 36 Pass through to the appropriate blinking points on the part 32 directly to light up. Alternatively, parts of the photoluminescent part 36 that are above the light sources 42 have a cutout so that from the light sources 42 emitted light can bring the corresponding Aufblinkstellen directly to shine without it before by the photoluminescent part 36 must pass through. The light sources 42 can be selected such that light emitted therefrom is relatively brighter than the luminescence emitted by the photoluminescent portion 36 is shown so that the flashing is easier to see for the viewer. For example, the light sources 38 be configured to emit cool white light having a color temperature of about 6000 K to 6500 K when the photoluminescent part 36 in a neutral white color, as described in the embodiment described above, luminescent.
  • Regarding 4 is a cross-sectional view of the badge 22 according to one embodiment. The badge 22 includes a housing 46 with the visible part described above 28 and a back part 48 who is on the vehicle 26 can be attached. The visible part 28 can be arcuate, whereas the back part 48 can be substantially linear. Every part 28 . 48 can be constructed of a rigid material such as plastic and by means of ultrasonic welding or Laser welding are assembled. Alternatively, the parts can 28 and 48 be assembled by injection molding with low pressure.
  • With regard to the illustrated embodiment, the visible part 28 be metallized to the plaque 22 to give a metallic appearance. For example, a metallic layer 50 by means of partial vacuum deposition on the underside of the visible part 28 be applied. The metallic layer 50 should be transparent and / or translucent to allow light from an inside 52 through them to an outside 54 can occur. According to one embodiment, the photoluminescent part covers 36 the metallic layer 50 and can over the metallic layer 50 be applied as a varnish or other coating. In an alternative embodiment, the photoluminescent part 36 shaped or otherwise in the visible part 28 of the housing 46 to get integrated.
  • Still referring to 4 can the light sources 42 on a flexible printed circuit board (PCB) 56 be provided in the housing 46 attached and near the visible part 28 is positioned. The light sources 42 can each be positioned directly below the respective flashing points and emit light pulses in the direction of the corresponding flashing points to produce brilliant illumination. Optionally, the light sources 42 Focusing optics include to assist in concentrating the light on the respective Aufblinkstellen. With regard to the illustrated embodiment, the PCB should 56 be substantially transparent and / or translucent to keep them away from the light sources 42 emitted light for excitation of the photoluminescent part 36 through there. As shown, the light sources can 38 relatively further away from the visible part 28 be positioned to allow a greater distribution of light in the direction of the photoluminescent part 36 to allow. For example, the light sources 38 on a PCB 58 be provided at the rear 48 is secured. The PCB 58 can a white solder mask 60 include to reflect incident light thereon.
  • According to one embodiment, the photoluminescent part 36 a Lambertian part, ie the apparent brightness of the photoluminescent part 36 is substantially constant regardless of the observer's viewing angle. Thus, converted light from the photoluminescent part 36 emitted in many directions to the outside. In terms of in 4 As shown, a portion of the converted light may pass through the metallic layer 50 pass through and part 32 of the visible part 28 be issued. Another part of the converted light can be found in the interior of the case 46 be emitted and on the white solder mask 60 the PCB 58 fall. Thus, the converted light to the photoluminescent part 36 to be directed back and pass through it, before it finally, by means of the part 32 of the visible part 28 from the case 46 is issued. This helps to ensure that the visible part 28 has an optimal amount of luminescence. Furthermore, the provision of the white solder mask helps 60 on the PCB 58 Also, be sure to get an optimal amount of from the light sources 42 emitted light the photoluminescent part 36 reached. For example, it is possible for some of the light to be from one or more of the light sources 42 is emitted from the photoluminescent part 36 is reflected, resulting in lowered excitation of the photoluminescent part 36 leads. Thus, by providing a means for redirecting the light back toward the photoluminescent portion 36 , a misleading light coming from the light sources 42 comes and in the case 46 Another opportunity is given to the photoluminescent part 36 to stimulate.
  • Regarding 5 is a cross-sectional view of the badge 22 shown according to an alternative embodiment. The badge 22 includes a housing 46 with the visible part 28 as described above, and a rear part 48 passing through attachment points 62 on a vehicle 26 can be secured. Any practical means can be used to attach the badge 22 at the vehicle 26 including any known process for flush mounting the badge 22 on a vehicle 26 , The visible part 28 can essentially appear prismatic, leaving the badge 22 is configured to resemble the colors formed by refraction of light through a prism. The back part 48 can be essentially linear and can be a dark, high-gloss material, eliminating all circuits of the badge 22 and attachment points 62 are covered.
  • The badge 22 contains multicolored light sources 64 configured to illuminate in multiple colors, such as an RGB LED with separate red, green and blue LED chips therein. The multicolored light sources 64 are in certain places to the plaque 22 around. Each multi-colored light source 64 can also be operated such that pulsed different light colors at predefined locations within the badge 22 be issued.
  • According to one embodiment, a light pulse having a first color from a given multicolor light source 64 last a short period of time from about 1/50 to 1/100 of a second. Next, a light pulse with a second color from the multicolored light source 64 last a short period of time from about 1/50 to 1/100 of a second. This process can be multi-color with any multicolor light source 64 go on like this. Each multi-colored light source 64 can be pulsed randomly or with a predefined pattern of colors. In addition, each multi-colored light source 64 a variable electric current is supplied to adjust the luminous intensity for each pulse of colored and / or white light. For example, the current may vary within a range that is one to five times the quiescent current. By using multicolored light sources 46 , each pulsing at different times with different colors, it is possible that the badge 22 has a prismatic appearance, meaning that the badge 22 seems to resemble the colors formed by refraction of light through a prism.
  • In an alternative embodiment, a multicolor light source 64 in a series of colors, as described above, while any remaining light sources 38 or multicolor light sources 64 that are in the plaque 22 to emit white light. The multicolored light sources 64 can during a steady state by simultaneously letting each individual light emitting diode in the multicolored light source 64 is, generate white light. Furthermore, the light sources 38 that emit white light, continue to have a constant color and brightness, or may flicker.
  • A light diffuser 44 is between the visible part 28 of the housing 46 and the multicolored light source 64 molded or alternatively installed. For example, the light diffuser 44 Be a layer on the bottom of the visible part 28 applied by partial vacuum deposition. The diffuser 44 may be clear, translucent, or opaque, including colored, and generally acts to diffuse light from the multicolor light sources 64 so that hotspots and shadows are eliminated. The inner surface and / or outer surface of the badge 22 may be coated or roughened or microfaceted to aid in light scattering performance. In addition, the diffuser 44 curved, such as curved outwards or having a concave shape, as in 5 shown to optimize the light scattering effect. In alternative embodiments, a light-diffusing material may be applied or at some or all of the light sources 38 that are in the plaque 22 be arranged.
  • Regarding 6 is a cross-sectional view of the badge 22 according to one embodiment. A light diffuser 44 covers the photoluminescent part 36 , The photoluminescent part 36 Can be used as a paint or other coating on a surface of the light diffuser 44 be applied. In an alternative embodiment, the light diffuser 44 and / or the photoluminescent part 36 in the visible part 28 of the housing 46 molded or otherwise integrated.
  • Multicolored light sources 64 can on a flexible PCB 56 be provided in the housing 46 attached and near the visible part 28 is positioned. Multicolored light sources 64 each may be positioned directly under the respective flashing locations, as described above, and output light pulses toward respective flashing locations to produce illumination of light of various colors, thereby creating unique aesthetic features such as the appearance of the badge 22 as prismatic. Optionally, multi-colored light sources 64 Focusing optics include to assist in concentrating light on the respective Aufblinkstellen. As discussed above, the PCB should be 56 be substantially transparent and / or translucent, so from the light sources 38 emitted light can pass through them to the photoluminescent part 36 to stimulate.
  • As shown, the light sources 38 relatively further from the visible part 28 Be positioned so that a greater distribution of light in the direction of the photoluminescent part 36 is possible. For example, the light sources 38 on a PCB 58 be provided at the rear 48 is attached. The PCB 58 can a white solder mask 60 for reflection of incident light. The greater relative distance of the light sources 38 compared to the multicolored light sources 64 can also help create a look of greater depth within the badge 22 provide.
  • According to one embodiment, the photoluminescent part contains 36 a first and second photoluminescent portion 40a . 40b containing various photoluminescent structures 10 which are excitable by light of a different wavelength in an interwoven or striped pattern. Each photoluminescent portion may be in any direction and with a practical width to produce any desired lighting effect. By using a stripe pattern, it is possible that that of the first and second photoluminescent portions 40a . 40b emitted combination light appears in a homogeneous color.
  • Additional photoluminescent sections can be found in the sticker 22 be crossed with each other. The additional photoluminescent sections can be separated by the light source 38 or in combination with the first and second photoluminescent sections 40a . 40b be stimulated to produce a wide range of colors and effects. In addition, the light source 38 the intensity of the light emitted by it on the basis of a predefined event, such as whether the vehicle 26 is operated during the day or at night, or by any other in the vehicle 26 data received vary.
  • In operation, the light sources 38 Emit light at a first and second wavelength, whereby the first and second photoluminescent portions 40a . 40b be stimulated. That of the first and second photoluminescent sections 40a . 40b emitted light can mix, whereby a substantially white light is emitted. In an alternative embodiment, the first and second photoluminescent portions may be 40a . 40b mix in any color that is necessary, any natural color of the badge 22 on the basis of the creation of the plaque 22 used material to remove. For example, plastics such as polycarbonate may inherently have a yellowish tone. However, this tone can be achieved through the use of photoluminescent structures 10 be masked, reducing the badge 22 lights up and appears in any desired color. Alternatively, any type of light source may be multicolored 64 or white 38 , used to the plaque 22 to light in any desired color.
  • With the excitation of the photoluminescent structure 10 , making parts of the badge 22 light in a first color, some or all multicolored light sources 64 randomly shine in multiple colors, causing the badge 22 may appear prismatic. Each multi-colored light source 64 can switch between pulsing multiple colors and an off state. Alternatively, any multicolor light source 64 between a flashing in several colors and a condition in which the multicolored light source 64 White light emitted, change. Still alternatively, it is contemplated that each multicolor light source 64 can switch between any combination of flashing in multiple colors, emitting white light and emitting no light. In an alternative embodiment, the multicolor light sources 64 illuminate individually with unique, pre-defined intervals, while every other light source in the plaque 22 is kept in an off state.
  • Regarding 7 is a box diagram of a vehicle 26 shown in which a prismatic plaque 22 is implemented. The badge 22 includes a controller 66 that with the light sources 38 . 64 is in communication. The control 66 can a memory 78 with instructions contained therein, by a processor 80 the controller 66 be executed include. The control 66 Can the light source via a power supply 72 that are in the vehicle 26 is located, supplying power. In addition, the controller 66 be configured to the light output of each light source 38 . 64 based on feedback to be controlled by one or more vehicle control modules 74 such as, but not limited to, a chassis control module, engine control module, steering control module, brake control module, or the like, or a combination thereof. By controlling the light output of the light source 38 . 64 can the plaque 22 in various colors and / or patterns to provide an aesthetic appearance, such as a prismatic appearance, or to provide vehicle information to an intended viewer. For example, that of the badge 22 provided lighting for a variety of vehicle applications, including, but not limited to, a car detection feature, a remote start indicator, a door lock indicator, a door-ajar indicator, a light operation, etc.
  • The badge 22 may have a constant monochrome or multicolor lights during operation. For example, the controller 66 one of several multicolored light sources 64 in the plaque 22 cause it to illuminate in several colors at a predefined interval. At the same time, the remaining multiple light sources 38 . 64 illuminate with a steady color or light up through multiple colors and / or through the controller 66 be put into an off state. In one embodiment, the controller is 66 configured to ensure that every multicolor light source 64 lit in a red color at random, followed by a blue color followed by a green color, or combinations thereof. The control 66 can be any light source 38 . 64 quickly light up in any color. For example, any light source 38 . 64 for 1/50 to 1/100 of a second light up. In addition, the controller 66 the every light source 38 supplied energy vary in a range corresponding to one to five times the quiescent current to vary the color and brightness of each lighting. The control 66 can also use multiple colors within a single multicolor light source 64 light up simultaneously, creating additional color configurations.
  • In another embodiment, the photoluminescent part 36 periodically have monochrome or multicolor lights. For example, the controller 66 the light source 38 periodically cause only the first one To emit light wavelength to cause the photoluminescent structure 10 periodically lit in the first color. Alternatively, the controller 66 cause the light source to emit only the second wavelength of light periodically to cause the photoluminescent structure 10 periodically lit in the second color. Alternatively, the controller 66 the light source 38 simultaneously and periodically emit the first and second wavelengths of light to cause the photoluminescent structure 10 periodically lit in a third color, which is determined by an additive light mixture of the first and second color. As yet another alternative, the controller 66 the light source 38 to switch between periodically emitting the first and second wavelengths of light to cause the photoluminescent structure 10 by periodically alternating by alternating the first and second colors. The control 66 can the light source 38 cause the first and / or second wavelengths of light to be emitted periodically at a regular time interval and / or an irregular time interval. A multicolored light source 64 can also distinguish between discrete colors with a predefined interval simultaneously with the photoluminescent structure 10 to shine. Thus, the badge 22 in any color based on a combination of photoluminescent structures 10 appear while at the same time solid dots in many different colors flicker to a prismatic look in the plaque 22 to accomplish.
  • With regard to the above examples, the controller may 66 the intensity of the light sources 38 emitted light by pulse width modulation or current control modify. In some embodiments, the controller may 66 be configured to a color of the emitted light by emitting control signals for adjusting an intensity or energy output level of any of the light sources 38 . 64 adjust. By adjusting the range of intensities emitted by the light source 38 can be output, the concentration and proportions of the photoluminescent structures 10 in the photoluminescent part 36 and the types of photoluminescent materials present in the photoluminescent moiety 36 are used to act to produce a range of hues of the emitted light by mixing the first emission with the second emission. In addition, varying the range of intensities of the multicolor light sources 64 any appearance features (such as prismatic appearance) of the badge 22 accentuate.
