Patent Issued for Lighting System for Accenting Regions of a Layer and Associated Methods

July 2, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Lighting Science Group Corporation (Satellite Beach, FL) has been issued patent number 8754832, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Maxik, Fredric S. (Indialantic, FL); Bartine, David E. (Cocoa, FL); Soler, Robert R. (Cocoa Beach, FL); Oostdyk, Mark Andrew (Cape Canaveral, FL); Widjaja, Addy S. (Palm Bay, FL); Regan, Matthew (Melbourne, FL).

This patent was filed on January 30, 2013 and was published online on June 17, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Making a picture, character, or otherwise identifiable image appear on a surface has usually involved the projection of the image on an otherwise blank surface. Moreover, the progression of a sequence of images, such as simulating motion, has tended to include either a series of projecting devices working in sequence to project the images, or a single projecting device that moves or rotates. However, such systems typically require the environment in which the image is to be perceived to be relatively darker, or the image may be difficult to perceive. Moreover, the projection of an image onto a non-blank surface makes the image difficult to recognize.

"Images have been embedded in random, pseudo-random, or otherwise non-recognizable patterns. This is useful for entertainment, where an image becomes apparent where it once was not apparent. For example, autostereograms are well known. However, prior embedded images have typically relied on biological responses, such as the decoupling of eye convergence, in order for the embedded image to become apparent, and not all observers are able to accomplish such decoupling. Other systems rely on a filter to be positioned intermediate the embedded image and the observer, usually in the form of eyewear. These systems are generally undesirable, as the eyewear is not conducive to ordinary activities. Accordingly, there is a need for a system for eliciting embedded images without impeding the activity of the observer, and that is readily observable by all observers.

"This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "With the foregoing in mind, embodiments of the present invention are related to a system for accenting a region of a layer comprising a lighting system that includes a plurality of light sources and a layer configured to be applied to a surface of a structure. The layer may include a first region having a first surface scatter profile and a second region having a second surface scatter profile. The light emitted by the plurality of light sources may combine to form a polychromatic combined light. Additionally, the first surface scatter profile may be configured to diffusively scatter a combined light including a first wavelength. Furthermore, the second surface scatter profile may be configured to diffusively scatter a combined light including a second wavelength. The combined light may be at least one of a first polychromatic light including the first wavelength and excluding the second wavelength and a second polychromatic light including the second wavelength and excluding the first wavelength.

"Another embodiment of the present invention is related to a system for accenting a region of a layer comprising a lighting system that includes a plurality of light sources and a computerized device operably connected to each of the plurality of light source. The computerized device may be configured to individually operate each of the plurality of light sources. The lighting system may further comprise a layer configured to be applied to a surface of a structure. The layer may comprise a first region and a second region, wherein each of the first region and the second region have a surface scatted profile configured to diffusively scatter a combined light including a first scattering wavelength. The plurality of light sources may comprise a first light source positioned generally adjacent to the first region and a second light source positioned generally adjacent to the second region. The light emitted by the first light source may not be incident upon the second region and light emitted by the second light source may not be incident upon the first region. The computerized device may be programmable to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the first scattering wavelength at a time.

"Another embodiment of the present invention is related to a system for accenting sub-surface regions comprising a lighting system substantially as described above. A first applique may be formed into a first image and adapted to be applied to a surface such that light from the first light source is incident thereupon and light from the second light source is not incident thereupon. A second applique may be formed into a second image and adapted to be applied to the surface such that light from the second light source is incident thereupon and light from the first light source is not incident thereupon. Each of the first applique and second applique may be configured to diffusively scatter a scattering wavelength within the visible spectrum. The computerized device may be configured to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the scattering wavelength at a time.

"Another embodiment of the present invention is related to a system for accenting sub-surface regions comprising a lighting system substantially as described above. Again, a first applique may be formed into a first image and adapted to be applied to a surface such that light from the first light source is incident thereupon and light from the second light source is not incident thereupon. A second applique may be formed into a second image and adapted to be applied to a surface such that light from the second light source is incident thereupon and light from the first light source is not incident thereupon. Each of the first applique and second applique may include a color conversion material configured to convert a source light including a source wavelength into a converted light including a second wavelength within the visible spectrum. The computerized device may be configured to selectively operate the first light source and the second light source such that only one of the first light source and the second light source emits light comprising the scattering wavelength at a time.

"Yet another embodiment of the present invention is related to a layer that is applicable to a surface of a structure comprising a pseudo-random pattern comprising at least one of a variety of shapes, a variety of colors, and a variety of textures. A first region may have a first surface scatter profile that diffusively scatters a combined light comprising a first wavelength, and a second region having a second surface scatter profile that diffusively scatters a combined light comprising a second wavelength. Each of the first region and the second region may be configured to diffusively scatter light so as to depict an image embedded in the pseudo-random pattern. The image depicted by the first region may not be observable when light incident thereupon does not include the first wavelength, and the image depicted by the second region is not observable when light incident thereupon does not include the second wavelength.

"Another embodiment of the present invention is related to a method of using the above system that may comprise the steps of emitting a first combined light including a first wavelength equal to a diffuse scattering wavelength of the first region and excluding a second wavelength equal to a diffuse scattering wavelength of the second region. The method may also include diffusively scattering the first combined light from the first region, emitting a second combined light including the second wavelength and excluding the first wavelength, and diffusively scattering the second combined light from the second region.

"Still another embodiment of the present invention is related to a method of accenting a region of a layer. The method may comprise the steps of providing a layer comprising a pseudo-random pattern having embedded therein a plurality of regions. Each region may have an individual surface scatter profile configured to diffusively scatter an individual light wavelength, and each region depicting one image of a sequential series of images, and emitting a sequence of polychromatic light. Each polychromatic light may include one individual light wavelength that is diffusively scattered by one of the plurality of regions. The sequence of polychromatic light may be configured to correspond to the sequential series of images."
