Description

Title of the invention: Book with backlit pages Field of invention

[0001] The invention relates to books with backlit pages, in particular children's picture books. Prior art

[0002] There are currently a number of books on the book market that use light-emitting diode (LED) technology for various lighting effects. With these solutions, LEDs are inserted directly into the page of a book at a specific location in the illustration, whereby they create a spotlight effect. Similarly, end-beam optical fibers are also used, where the emitting end of the fiber is used instead of the LEDs themselves. The disadvantage of these solutions is that they do not allow for the illumination of more complex planar objects in 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.Using LEDs or fiber optics with end-beam emission is also technologically demanding, as the LEDs or fiber optic 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 registered Slovak utility model UVz No. 4 870 called Illuminated panel with an LED perimeter frame structure, in which the LEDs are arranged on the inner side of the perimeter frame structure with light emission from at least one illumination plane which is parallel to the plane of the transparent cover. The disadvantage of this technical solution is that it cannot be used for backlighting book pages.

[0004] Another well-known invention is described in English Patent GB No. 2503982 entitled Fiber Optic Greeting Card, which comprises a three-panel pouch with an internal cavity which contains a fiber optic bundle, various electronic components, a fabric layer and a removable panel, wherein a front face of the three-panel pouch contains a large opening thereon, through which the fabric layer is visible, and the fiber optic bundle contains various fiber optic strands each of which is inserted through the fabric layer and is visible through the front face of the greeting card, and a contact switch controls illumination of the fiber optic strands and insertion and removal of the removable panel or, alternatively, in an alternative embodiment, the removable panel may be pivotally attached to the pouch, whereby it pops out substantially from the cover when rotated around a pivot point. The disadvantage of this invention is that the end of the fiber optic bundle must be placed and anchored in a well-defined location and cannot be used to backlight each individual page of the book.

[0005] Another known invention is disclosed in U.S. Patent No. 8,960,936 entitled "Backlit Storybook for Visually Impaired Persons," which includes an audio and visual storybook comprising a book, a base, and an integrated backlight, each page of the book including pictures or words and the book itself being 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 including a speaker for audio to play a corresponding narration and to indicate when different pages should be turned. The disadvantage of this invention is that it does not use fiber optics or LED technology and cannot be used to backlight the pages of books.

[0006] Another known invention is disclosed in U.S. 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 connected to the article and at least one optical fiber connected to a light emitting module which projects from the article, the optical fiber having a light source outlet, which extends from an opening located on the article in the direction of the light conducting plate mounted in the opening, and the light emitting module is driven by at least one optical fiber connected to the light source outlet, from which light is projected towards the light conducting plate in order to produce a decorative lighting effect. The disadvantage of this invention is that it does not use LED technology and cannot be used to backlight the pages of books.

[0007] Another known invention is disclosed in U.S. Patent No. 20,060,066,094 entitled "Self-Illuminating Viewing Compartment Display Book", wherein the display book system includes 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, wherein a book portion may be appended thereto to form the display book system which is modified to provide a viewing compartment formed in association with the framed image portion to enable display of discrete objects, including three-dimensional objects such as figurines as well as pictures, opaque or translucent two-dimensional images, wherein an illumination capability is provided to enable a illumination of the displayed object (front or backlit), self-illumination or the frame itself can also be illuminated for decorative reasons. The disadvantage 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 above-mentioned disadvantages are largely eliminated by the backlit 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 attached, 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 attached to the inner part of the frame, in which a back side of a light-permeable printing layer containing content illustrations is attached to the front side 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] Further, preferably, at least one light-permeable print layer containing the content illustrations is attached to a light-permeable print layer containing the content illustrations.

[0011] Further, preferably, the light-conducting fiber is a side-emitting optical fiber or a light-emitting diode (LED) light string. 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 book pages, thus ensuring the possibility of reading even in the dark without the need for an additional light source. The applicability is made possible by inserting a side-emitting optical fiber or a light chain of LEDs into the frame of the book page, thereby achieving advanced color and light effects such as monotony, polychromy, dimming, color change, and brightness change, and thus achieving a special lighting effect where only selected areas or parts of the illustration light up.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 having a desired shape corresponding to the print. The invention can furthermore be used without a frame, whereby a side-emitting optical fiber or a light chain of LEDs can be inserted directly between the two protective layers using glued translucent hooks. The invention can furthermore be used when a single optical fiber frame is covered with several layers of translucent sheets, which are to be made of a highly translucent material, for example a film, and after partial printing and superimposing of these sheets, it is possible to obtain complex patterns which are changed and uncovered by turning the sheets over.The present invention may use a single backlighting method using a side-emitting optical fiber or a light chain of LEDs, or LEDs or combinations of the given methods. The present invention may be combined with other available solutions to make books more attractive, including the use of sound effects, removable page parts with puzzles, and sliding page parts.
