Description

Title of the invention: Backlit book Scope of the invention

[0001] The invention relates to books with backlit pages, in particular picture books for children. Prior state of the art

[0002] A number of books currently exist on the market that use light-emitting diode (LED) technology for various lighting effects. With these solutions, LEDs are directly embedded in the page of a book at a specific location within the illustration, thereby creating a spotlight effect. Similarly, end-beam optical fibers are also used, with the emitting end of the fiber being used instead of the LEDs themselves. The drawback of these solutions is that they do not allow for the illumination of more complex flat objects within the illustration, and it is not possible to illuminate blocks of text in such a way that they can be read comfortably even in the dark.The use of LEDs or optical fibers with end-beam emission is also technologically demanding, as the LEDs or optical fiber ends must be placed and anchored in a precisely defined location on each individual page of the book.

[0003] A known technical solution is disclosed in the Slovak registered utility model UVz No. 4870 called a Light Panel with a Perimeter Frame Structure with LEDs, wherein the LEDs are arranged on the inner side of the perimeter frame structure with light emission from at least one illumination plane that is parallel to the plane of the transparent cover. The disadvantage of this technical solution is that it cannot be used to backlight book pages.

[0004] Another well-known invention is described in English Patent GB No. 2,503,982 entitled "Fiber Optic Greeting Card," which comprises a three-panel pocket with an internal cavity containing a bundle of optical fibers, various electronic components, a fabric layer, and a removable panel. A front face of the three-panel pocket has a large opening through which the fabric layer is visible. The fiber optic bundle contains various strands of optical fibers, each inserted through the fabric layer and visible through the front face of the greeting card. A contact switch controls the illumination of the optical fiber strands as well as the insertion and removal of the removable panel. Alternatively, in another embodiment, the removable panel can be pivotally attached to the pocket, thereby extending from it. essentially the pocket when rotated around a pivot point. The drawback of this invention is that the end of the fiber optic bundle must be placed and anchored in a well-defined location and it cannot be used to backlight each individual page of the book.

[0005] Another known invention is disclosed in US Patent No. 8,960,936 entitled "Backlit Storybook for Visually Impaired Persons," which comprises an audio-visual storybook including a book, a base, and integrated backlighting. Each page of the book includes pictures or words, and the book itself is placed on the base to allow each individual page to backlight the pictures and words to provide a high-contrast illuminated character pattern easily readable by visually impaired persons. The system further includes a speaker for audio to play a corresponding narration and to indicate when the different pages should be turned. The drawback of this invention is that it does not use fiber optics or LED technology and cannot be used to backlight book pages.

[0006] Another known invention is disclosed in US Patent No. 200,600,769 entitled "Decorative Application with Light-Conducting Assembly Made of Optical Fibers," comprising an article to be decorated, a light-conducting plate attached to the article, and at least one optical fiber attached to a light-emitting module projecting from the article. The optical fiber has a light-source output extending from an opening on the article in the direction of the light-conducting plate mounted in the opening. The light-emitting module is controlled by at least one optical fiber attached to the light-source output, from which light is projected toward the light-conducting plate to produce a decorative lighting effect. The drawback of this invention is that it does not utilize LED technology and cannot be used to backlight book pages.

[0007] Another known invention is disclosed in US Patent No. 20,060,066,094 entitled "Display Book with Viewing Compartment and Self-Illumination," in which the display book system comprises a frame that defines a viewing window, which defines a viewing compartment in a position aligned with the window of the frame, for receiving a subject to be displayed and which is visible through the viewing window of the frame, in which a book portion can be attached thereto to form the display book system, which is modified to provide a viewing compartment formed in association with the framed picture portion to permit the display of discrete objects, including three-dimensional objects such as figurines as well as pictures, opaque or translucent two-dimensional pictures, in which a lighting capability is provided to permit a The object being displayed can be illuminated (frontally or backlit), self-illuminating, or the frame itself can also be illuminated for decorative purposes. The drawback of this invention is that it does not use optical fibers or LED technology and cannot be used to backlight book pages. Summary of the invention

[0008] The aforementioned disadvantages are largely eliminated by the backlit page book of the present invention, which comprises at least two light-impermeable protective films with cutouts, to which light-permeable printing layers containing content illustrations are fixed, between which a light-conducting fiber is disposed, or which comprises a frame having an internal shaped cutout with a frame opening formed on the side thereof, in which a light-conducting fiber is disposed, which is fixed to the internal part of the frame, in which a back side of a light-permeable printing layer containing content illustrations is fixed to the front face of the frame.

[0009] Preferably, at least one light-impermeable protective film with cutouts is disposed between the frame and the light-permeable printing layer containing the content illustrations.

[0010] In addition, preferably, at least one light-permeable printing layer containing the content illustrations is attached to a light-permeable printing layer containing the content illustrations.

[0011] Furthermore, preferably, the light-conducting fiber is a side-emitting optical fiber or a luminous string of light-emitting diodes (LEDs). Brief description of the drawings

[0033] The present invention, combined with an ingenious and complex design, can be used not only to make illustrated books more attractive, but also to backlight all the pages of books, thus ensuring the possibility of reading even in the dark without the need for an additional light source. This applicability is made possible by inserting a side-emitting optical fiber or a string of LEDs within the book page, enabling advanced color and lighting effects such as monotony, polychromy, gradation, color change, and brightness change, thereby producing a special lighting effect where only selected areas or parts of the illustration are illuminated.Another advantage of the present invention is that the lighting effect can be achieved even without a protective layer by an internal cutout in the frame with a desired shape corresponding to the print. The invention can also be used without a frame, as a side-emitting optical fiber or a string of LEDs can be inserted directly between the two protective layers using glued translucent clips. The invention can further be used when a single optical fiber frame is covered with several layers of translucent sheets, which must be made of a highly translucent material, for example, a film. After partial printing and layering of these sheets, it is possible to obtain complex patterns that are modified and revealed by turning the sheets over.The present invention can use a single backlighting method using a side-emitting optical fiber or a string of LEDs, or LEDs, or combinations thereof. The present invention can be combined with other available solutions to make books more attractive, including the use of sound effects, removable puzzle pages, and sliding page sections.
