New Description: [New Technology Field] This creation is about an illuminated keyboard, especially one that avoids the light-shielding layer and reflection, and the adhesive part is opened to prevent light from overflowing from the side of the light guide plate. The luminous keyboard. [Prior Art] With the advancement of technology, the illuminated keyboard will gradually evolve into the main stream of the keyboard, and the illuminated keyboard can be used in places where the light is less abundant. In particular, the notebook computer with an illuminated keyboard allows the user to easily use the notebook in a variety of situations. In addition, the illuminated keyboard can also be used with different colors in order to meet the needs of users for innovation and thrill. Referring to the first embodiment, an illuminated keyboard structure includes a light guide plate 11, a light source 12, a keyboard body 13, a light shielding layer 14, a first reflection sheet 15, and a second reflection sheet. The light guide plate 11 has a light incident surface 111, a light exit surface 112, a bottom surface 113 and a side surface 114. The light source 12 is disposed on the light incident surface m of the light guide plate u, and the keyboard body 13 is disposed on the light exit surface I of the light guide plate 〗? The light-shielding layer 14 is disposed between the light-emitting surface 112 of the light guide plate 11 and the keyboard body 13 . The first reflection sheet 15 is disposed on the bottom surface 113 of the light guide plate 11 , and the second reflection sheet 16 is disposed on the side surface 114 of the light guide plate 11 . The lanthanide system is disposed in the accommodating space formed by the first reflective sheet 15 and the second reflective sheet 16, and is characterized in that the light generated by the light source 12 is effectively reflected back into the light guide plate u by the second reflective sheet 16 The luminous efficiency and overall brightness of the illuminated keyboard can be greatly improved, and the intensity or quantity of the light source can be effectively reduced under the premise of maintaining the same brightness, thereby achieving the goal of saving power and reducing the cost, and the structure of the conventional illuminated keyboard 10 Although the energy loss of the conventional luminescent disk can be greatly improved and the illuminating intensity and the quality are not good, the light of the light guiding plate 11 is still separated by the light shielding layer 14 and the second because the light shielding layer 14 and the second reflection sheet 16 are separated. The gap 17 between the reflection sheets 16 leaks out, affecting the light utilization efficiency. Referring to the second figure, in order to solve the problem of the gap 17, some manufacturers will increase the size of the light shielding layer 14 and attach the anti-folding sheet 161 of the upper edge of the second reflection sheet 16 to the light shielding layer. 14 bottom surface, although the φ method can avoid light leakage of the light guide plate 11, when the thickness of the light guide plate 11 used is thick, or the depth of the accommodating space formed by the first reflection sheet 15 and the second reflection sheet 16 When the battery is insufficient, it is easy to cause the glue to be opened after a long time of use, so that the second reflection sheet 16 is separated from the light shielding layer 14, and the light will still overflow from the edge of the light guide plate 11. In addition, the light-emitting keyboard will generate heat after being used for a long time, and the light guide plate 11 is heated. The light shielding layer 14, the first reflection sheet 15 and the second reflection sheet 16 have different materials and different expansion coefficients, and there is a potential risk of opening the glue.

When the time is used to generate heat, the glue is not opened, and since the side surface 414 of the light guide plate 41 and the first side wall 4421 have a distance D3, the deformation space of the light guide plate 41 is expanded and contracted, and the light guide plate 41 can be avoided. The light shielding layer 44 and the reflective layer 45 are opened to cause opening. In summary, the illuminated keyboard provided by the present invention can be provided with a reflexed portion at the periphery of the light shielding layer and the reflective layer, so that the adhesive portion of the light shielding layer M420756 and the reflective layer can be prevented from being opened, and the light is prevented from being guided by the light guide plate side. Edge overflow can improve the light utilization of the illuminated keyboard. However, the above descriptions are only examples of the present invention, and the scope of the present invention cannot be limited. That is to say, according to the creation of the original "= and the modification, it should still belong to the strict coverage of this creation patent." Please check the Mingjian, and pray for the right, it is the right [simplified description] °
