It needs to be manually switched on and off, which is easy to be accidentally touched and not convenient. Moreover, most of the existing light emitting bookmarks are made by one-piece forming method, which lacks flexibility and cannot meet the various reading modes of the reader. Therefore, it is necessary to design a light emitting bookmark, so as to make the light more uniform and the use more flexible and convenient.

[0026] As Figures 1-3As shown, a three-fold light supplement bookmark based on grating diffraction includes two main boards 1 of folding design and a conductive copper foil tape 3, the end of the main board 1 is provided with a support plate 2, one of the main boards 1 is provided with a button cell 4, the button cell 4 is embedded in the main board 1, and the positive and negative poles of the button cell 4 are higher than the main board 1 and exposed outside, the other main board 1 is provided with a magnetic sheet 5, the magnetic sheet 5 is embedded in the other main board 1, and the upper and lower surfaces of the magnetic sheet 5 are higher than the main board 1 and exposed outside, one end of the conductive copper foil tape 3 is connected with the button cell 4 (connected with the positive pole of the button cell 4), and the other end is arranged on the magnetic sheet 5 (arranged on the lower end surface of the magnetic sheet 5), the conductive copper foil tape 3 is embedded in the two main boards 1 as a whole, a patch LED lamp 6 is connected to the conductive copper foil tape 3, the patch LED lamp 6 is arranged on one of the main boards 1, and is provided with a grating plate 7 in a matched manner, the grating plate 7 is located above the patch LED lamp 6, the patch LED lamp 6 is built in the main board 1, the magnetic sheet 5 is adsorbed on the button cell 4 after the two main boards 1 are folded, and the positive and negative poles of the button cell 4 are connected through the conductive copper foil tape 3 (loop connection) to supply power to the patch LED lamp 6. By designing the bookmark into a three-fold structure, the bookmark structure can be flexible and variously folded. The bookmark can be held in hand to illuminate the book, can be placed on the desk to free the hands, and can be inserted into the top of the book page to move with the book to illuminate in real time, which can greatly meet various reading modes and enhance the practicability of the light supplement bookmark. By additionally arranging the grating plate 7 at the patch LED lamp 6, the angle of light emission is enlarged, the light is more evenly dispersed, the light can cover a larger book page area, and the grating plate also makes the light less dazzling. The patch LED lamp 6 and the grating plate 7 herein belong to the prior art, and can be directly purchased or customized in actual application, for example, the grating plate 7 can adopt a 42-line grating plate of Zhouteli Technology Co., Ltd.
[0027] The main board 1 and the support plate 2 are connected through a flexible connection layer 8 and realize folding design, and the flexible connection layer 8 is made of transparent TPU soft glue. The two support plates 2 and the two main boards 1 are connected together through the flexible connection layer 8, and folding design can be realized, which has the advantages of low cost, convenient folding, mature technology and the like, and the transparent TPU soft glue material has the advantages of good flexibility, folding resistance, soft hand feeling and the like, and meets the folding requirement of the bookmark.
[0028] The connection between the main board 1 and the support plate 2 and the connection between the two main boards 1 are designed into an arc shape 9. The arc design at the connection not only facilitates folding the bookmark along the arc in the forward direction, but also has the effect of returning to the normal position when folding in the reverse direction.
[0029] The mainboard 1 is made of acrylic sheet. To further reduce costs, lighten weight, and ensure practicality, acrylic sheet is the preferred material. The support plate 2 is made of magnets or is made of acrylic sheet with built-in magnets, which helps to keep the bookmark straight by attracting the two ends when folded.
[0030] The conductive copper foil strip 3 comprises two sections: conductive copper foil strip A301 and conductive copper foil strip B302. One end of conductive copper foil strip A301 is connected to the positive terminal of the button battery 4, and the other end is connected to the surface-mount LED 6. One end of conductive copper foil strip B302 is connected to the surface-mount LED 6, and the other end is disposed on the lower end surface of the magnetic sheet 5. After the two mainboards 1 are folded, the magnetic sheet 5, carrying the conductive copper foil strip B302, is attracted to the negative terminal of the button battery 4. By combining the folding structure with the magnetic sheet 5, the circuit of the surface-mount LED 6 can only be connected and illuminated when the two mainboards 1 are folded, reducing the risk of accidental light activation.
[0031] Usage instructions:
[0032] Method 1:
[0033] like Figure 1 As shown, the illuminated bookmark of this application, in addition to illuminating the pages, also has the function of marking the reading position as a traditional bookmark. The user places the illuminated bookmark as... Figure 1 Fully unfold, the circuit is disconnected, the supplemental lighting stops, and the supplemental bookmark can be clipped into the book. The overall thickness of the supplemental bookmark of this application is less than 3mm, making it suitable for marking reading positions in a book.
[0034] Method 2:
[0035] like Figure 4 As shown, when the user folds the two motherboards 1 in an arc (bend), the bookmark circuit is connected and the surface-mount LED 6 lights up, and the bookmark length becomes shorter, allowing the user to hold it in their hand for flexible illumination of the book pages.
[0036] Method 3:
[0037] like Figure 5 As shown, the user can first bend and fold the two main boards 1 along the arc, and then fold the support plate 2 and the main board 1 against the arc (bend) so that the supplementary light bookmark stands on the table. For readers who like to hold books and read, the supplementary light bookmark can be folded in this way and placed between the reader and the book to illuminate the pages.
[0038] Method 4:
[0039] like Figure 6As shown, the user folds the bookmark in the folding mode of use mode three, inserts the support plate 2 of the bookmark into the page interlayer of the book 10, adjusts the light supplementing bookmark to a proper inclination angle, and can illuminate the read page, which is suitable for the scene of reading while lying on the bed or crouching or walking, is very flexible, and does not need to be held in hand, thereby freeing the hands.
[0040] In summary, the three-fold light supplementing bookmark effectively solves the problems of lacking a light guide structure, the concentrated light being relatively glaring in a small range, and the small coverage range only illuminating a local writing in the prior art.
[0041] The specific embodiments above cannot be used as a limitation on the protection scope of the utility model, and any alternative improvement or change made by the person skilled in the art to the embodiments of the utility model falls within the protection scope of the utility model.
