[Embodiment] In order to further understand the purpose, structure, features, and functions of the present invention, the following detailed description will be given in conjunction with the embodiments. According to the light guiding film structure disclosed in the present invention, the light guiding film structure is mainly applied to a button structure, and the light is guided to the button structure through the light guiding film to form a backlight source of the button structure. The fine button structure includes, but is not limited to, a button of a key desktop keyboard such as a handheld electronic product, a button of a notebook computer keyboard, a button switch of an M368076 button or other electronic products requiring backlight illumination. , as a function of the light _, 赖 or indication of the button structure. The specific embodiment will be implemented in a hand-held electronic g-ship _ as a supplement, but not limited to this. Please also refer to "Figure 1" and "Figure 8". Here, the "figure" diagram is an enlarged schematic view of a partial appearance of the light guiding film according to the present creation-embodiment. Fig. 2A is a side elevational view showing a light guiding film according to an embodiment of the present invention. > The light guiding film (1) according to the present invention is made of a transparent material, for example, selected from the group consisting of τρυ, pc, silic()ne, or any of the plastics, but not To this end, it is only necessary to allow light to pass through the film. The light guiding film has -10, and a light-emitting surface u and a light-emitting surface 13' are formed on the opposite sides of the diaphragm 1 (), and each of the light guides is formed on the surface 12 The silk 13 is a fine concavo-convex pattern 13 like a younger brother - "No". However, in the creation of the plural light guide wire, non-fine hairline (hair), the light guide wire 13 of the most ^ at least small phase 3_, the output (four) 峨 is very fine, The partially magnified shirt figure in the blue _ style indicates that Wang is the best face. For example, the forming method of the plural light guiding wire 13 is mainly based on the metal figure, the working surface 12 of the diaphragm 1 Into the general processing _ secret (four). The metal rolling surface protrudes from a plurality of sharp linear patterns (10), when the field is rolled on the working surface 12, the metal roller surface is sharp and straight rear 7 M368076 pattern and The film #10 is in close contact with each other, and the destructive cutting is performed on the surface 12, and after the above-described destructive cutting, a plurality of light guiding threads 13 can be formed on the working φ12. Moreover, in the rolling processing manner, a plurality of light guiding wires 13 structures are cut on the working surface 12, which has the advantage that the thickness of the diaphragm 1〇 is not particularly increased, and only the general physical structure is used. In the case of destruction, a plurality of light guiding wires 13 can be formed on the working surface u. Further, in the above specific embodiment, the fine structure of the plurality of material 敝 n is formed on the diaphragm 129 of the diaphragm 129 by the rolling process of the metal roller. However, this is only a description of the preferred embodiment and is not intended to limit the scope of the patent protection. This creation can also be used for calendering of the working surface] (can (4), on the roller, with the electric discharge machining I as the surface 12, and the monolithic sulfur wheel (four) force pressing the working surface U to contact with the electric discharge machining line, but A plurality of light guiding impurities 13 are formed on the surface η of the diaphragm 1 (). Therefore, regardless of the weight of the pressure plus 4 is a processing method, as long as the number of light guides is formed in the field of the K) The technical means 'is equally included in the scope of the patent of this creation. The 2B map is not a partial enlargement of the light guide film according to the present creation. It can be seen from the enlarged view that 'when a plurality of light guiding wires are arranged on the working surface 12 of the diaphragm '', the light guiding wire 13 structure of each strip has a generally concave groove (5)' and the shape of the groove can be A first reflecting surface 132 and a second reflecting surface 133 form a sharp angle. However, the angle of the portion of the groove 131 is only __. The preferred embodiment is described. M368076 is not limited to the lion's _. The shape (9) of the i3i in the village is counted as a circular arc (as shown in "3A" and "3B"). Mainly in: a linear pattern of a plurality of arc convexes (not shown) protruded from the surface of the roller, and is carried out on the working surface 12 by a curved straight line pattern, thereby forming a plurality of strips on the working surface 12. The light guiding wire 13 is formed, and each of the light guiding wires 13 is formed with a circular arc shaped groove 131. Further, the optimum depth L1 of the groove 131 may be approximately (10), and the optimum opening width W1 of the groove (3) is at least less than 〇3. And the optimum interval (four) between each of the grooves m is at least smaller than the 〇m. These light guide wires are used to form a plurality of fine passages (hair iine; > Next, a working layer 12 is further coated with a layer of ultraviolet curable paint (not shown), and the ultraviolet curable paint can be partially The parts are filled in the interior of each of the light guiding wires. Thereafter, the ultraviolet ray coating on the working surface η is cured by an ultraviolet light irradiation device (not shown), and ultraviolet rays are used on the working surface u. The advantage of the hard coating is that the groove (3) of the light guiding wire 13 is too fine, and the film K) is made of a surface and has a structural elasticity, so when cutting on the working surface 12 After a plurality of light guiding wires 13, there is a possibility that the plastic film of the diaphragm 10 will cause the light guide 卿U-shaped groove (3) to gradually close. Therefore, it is necessary to form a solidified state at the opening of the groove 131 by the ultraviolet ray hardening paint, thereby fixing the opening of the groove 丨 31. As shown in Fig. 2C, it is a side view showing a reflective film attached to the light guiding film of the present invention. The reflective film 2 is attached to the working surface 12 of the diaphragm 1 . M368076 In detail, it mainly has a reflecting surface and a bottom surface 22 respectively on the opposite side of the 20 _ pair, and the reflecting surface 21 of the side is fitted to the (4) working surface U. When the reflective film 2G and the film 1 () are attached to each other, a -first adhesive material 3 可 may be disposed between the reflective film 2 〇 and the film. The first-viscosity material can be made of a viscous polymer material which is still translucent, and the first adhesive layer (4) is used as a medium, and the film 1 〇 and the reflective 臈 2 〇 are attached to each other. Together, the reflective surface 21 of the anti-〇 is corresponding to a plurality of light guiding filaments 13 (as shown in the "Figure"). Finally, a metal dome 50 is placed on the bottom surface 22 of the reflective film 20.蝉吕之' is provided with a second adhesive tape 4〇 on the bottom surface 22, and a second adhesive tape 4〇 as a medium, and a metal elastic piece (4) on the bottom surface 22 (such as "2D 2 = No. In addition, the above-mentioned diaphragm 1 () can be disposed on the 2 side of the electronic product: for example, the light-emitting surface u of the diaphragm (1) is set on a button to receive the nrr light-emitting surface 11 and the button The bottom surfaces of the 6G correspond to each other. When the button 6 is pressed, the button 6_ is pressed against the 1G, and the diaphragm 10 is moved upright and the metal dome 5G is actuated to generate a downward elastic displacement, so that the metal The shrapnel shows that the Lum PM touches the corresponding contact on the circuit board (the electronic signal of the function of the button is not a, x mirror, and the function of the button 6 。. After each light is irradiated toward the cymbal 1Q, the light can be separately entered, ... 13 internal And the light is filled in the light guiding wire 13, and the working surface of the film 10 is covered with a plurality of fine light-emitting wires. In other words, §, i in a plurality of light guiding wires 13 structure It is very fine and tightly arranged, so when the light enters this, it also starts from the k-leading silk 13 Will accumulate along the groove 131 and fill the M368076 with the groove m. Thus, through these light guiding lines 13, the light can be uniformly absorbed and uniformly formed on the (four) working surface 12 - After the light-receiving state is finally completed, the light is refracted to the light-emitting surface u by a plurality of light guiding wires I3.
