Description

TECHNICAL FIELD

[0001] The present utility model relates to a book with backlit pages, in particular a children's picture book. BACKGROUND

[0002] At present, there are many books on the market that use LED technology to achieve various light effects. With these solutions, at specific locations in the illustrations, LEDs are directly inserted into the pages of the book, where they produce a spotlight effect. Similarly, optical fibers with end-beam are also used, in which the emitting end of the optical fiber is used instead of the LED itself. The disadvantage of these solutions is that they do not allow the illumination of more complex planar objects in the illustrations, and they cannot illuminate the block of text in such a way that it can be comfortably read even in the dark. The use of LEDs or optical fibers with end-beam emission is also technically demanding, as the end of the LED or optical fiber must be placed and anchored in a precisely defined point on each individual page of the book.

[0003] A known technical solution, entitled "Light panel with a perimeter frame structure with LEDs", is disclosed in registered Slovak utility model No. UVz4870, in which LEDs are arranged on the inner side of the perimeter frame structure, with a light emission having at least one illumination plane parallel to the plane of the transparent cover. The disadvantage of this technical solution is that it cannot be used to illuminate the pages of a book from the back.

[0004] Another well-known invention is described in British patent No. GB 2503 982, entitled "Optic fibre greeting card", which comprises a three-panel pocket with an internal cavity containing an optical fibre bundle, a variety of electronic components, a fabric layer and a removable panel, in which the front face of the three-panel pocket contains a substantial opening through which the fabric layer is visible, and the optical fibre bundle contains a plurality of fibre optic strands, each of which is inserted through the fabric layer and visible through the front face of the greeting card, and a contact switch controls the illumination of the fibre optic strands and the insertion and removal of the removable panel, or alternatively, in an alternative embodiment, the removable panel is pivotably attached to the pocket, whereby when rotated about the pivot point, the removable panel substantially leaves the pocket. The disadvantage of this invention is that the end of the optical fibre bundle must be placed and anchored in a precisely defined location, and furthermore, it cannot be used to illuminate each individual page of a book from the back.

[0005] Another known invention is disclosed in U.S. Patent No. 8 960 936 entitled "Backlit storybook for the visually impaired" which includes an audio and video storybook comprising a book, a base and an integral backlight, wherein each page of the book comprises images or text and the book itself is placed on the base to enable each individual page to be illuminated from the back with the images and text in turn providing bright lettering of high contrast that is easy to read for the visually impaired, wherein the system further comprises an audio speaker for playing a corresponding narration and indicating when a different page should be turned to. The disadvantage of this invention is that it does not use fiber optic or LED technology and cannot be used to illuminate the pages of a book from the back.

[0006] Another known invention is disclosed in U.S. Patent No. 200600769 entitled "Decorative application with a light-conducting assembly made of optical fibres" which includes an article to be decorated, a light guide plate connected to the article and at least one optical fiber connected to a light emitting module protruding from the article, the optical fiber having a light source outlet extending from an opening provided on the article in the direction of the light guide plate mounted in the opening, and the light emitting module is controlled by the at least one optical fiber connected to the light source outlet, light is projected from the light source outlet towards the light guide plate to produce a decorative light effect. The disadvantage of this invention is that it does not use LED technology and cannot be used to illuminate the pages of a book from the back.

[0007] Another known invention is disclosed in US Patent No. 20060066094 entitled "Display book with viewing compartment and self-illumination", wherein the display book system comprises a frame which delimits a viewing window, a viewing compartment is delimited in a position aligned with the window of the frame for housing an object to be displayed and the viewing compartment is visible through the viewing window of the frame, wherein a book portion can be annexed to the viewing compartment to form a display book system which is modified to provide a viewing compartment formed in association with a picture portion with a frame to allow the display of discrete objects including three-dimensional objects such as figurines and pictures, two-dimensional opaque or semi-transparent pictures, wherein an illumination capacity is provided to allow the illumination of the displayed objects (from the front or from the back), the self-illumination or the frame itself can also be illuminated for decorative purposes. The drawback of this invention is that it does not use optical fiber or LED technology and cannot be used to illuminate the pages of the book from the back. Utility model content

[0008] The book with backlit pages of the present utility model largely eliminates the above-mentioned drawbacks, the essence of which is that the book comprises at least two shielding light-impermeable films with cut-outs, a light-permeable printed layer containing content graphics is attached to the at least two shielding light-impermeable films, light guide fibers are arranged between the at least two shielding light-impermeable films, or the book comprises a frame with an internally shaped cut-out and a frame opening formed on the side of the frame, light guide fibers are arranged in the internally shaped cut-out and attached to the internal part of the frame, wherein one back of the light-permeable printed layer containing content graphics is attached to the front of the frame.

[0009] Preferably, at least one shielding light-impermeable film with cut-outs is attached between the frame and the light-permeable printed layer containing content graphics.

[0010] It is also preferable that at least one light-permeable printed layer containing content graphics is attached to one light-permeable printed layer containing content graphics.

[0033] Industrial applicability

[0034] The utility model clever and complex design can not only be used for making the book with illustrations more attractive, but also can be used for illuminating all pages of the book from the back, thereby ensuring that even in the dark, the book can be read without using additional light sources. The applicability is made possible by inserting the side-emitting optical fiber or LED light chain into the frame of the book page, which makes it possible to achieve advanced color and light effects, such as monochrome, multicolor, dimmability, color variability, and brightness variability, thereby achieving special lighting effects of only selected areas or selected parts of the illustrations emitting light. Another advantage of the utility model is that even without the light-blocking layer, the lighting effect can be achieved by having an internal cutout in the frame with a desired shape corresponding to the printed layer. The utility model can also be used without the frame, in which the side-emitting optical fiber or LED light chain can be directly inserted between the two light-blocking layers with a glued translucent hook. The utility model can also be used when covering a single optical fiber frame with several layers of translucent paper, which must be a highly translucent material, such as a film, and after partially imprinting and stacking these papers, complex patterns can be achieved by changing and unfolding by quickly flipping through the papers. The utility model can illuminate from the back using only one of the following methods or a combination of given methods: using side-emitting optical fiber or LED light chain, or LED. The utility model can be combined with other feasible solutions to make the book more attractive, especially by using sound effects, removable page parts with puzzles, and sliding page parts.
