[0008] 再者,发光元件16设置于导光板12的侧边,用以提供光线射入导光板12。 [0008] Further, the light emitting element 16 disposed on the side of the light guide plate 12 to provide light incident on the light guide plate 12. 而导光板12设置于反光板11上,且其下表面具有用以聚集且散射光线的多个导光点121。 And the light guide plate 12 is provided on the reflecting plate 11, and a lower surface having a plurality of light guide points 121 and to collect light scattering. 多个导光点121依对应多个按键15的位置而被设置。 A plurality of light guide 121 by location points corresponding to the plurality of keys 15 is provided. 其中,于光线射入导光板12时,光线得以被扩散至整个导光板12,且多个导光点121会因其为油墨材质的关系而将光线往上及往下散射,往上散射的光线会依序通过按键底板13的多个穿孔131以及薄膜线路板14而投射至多个按键15,而往下散射的光线会再经由反光板11的辅助而使光线向上反射,以使发光元件16所提供的光线可被完善利用。 Wherein light incident on the light guide plate 12, light can be diffused throughout the light guide plate 12, and a plurality of light guide points 121 due to their relationship to the ink material and the light scattering up and down, up scattered button will light sequentially the bottom plate 131 of the plurality of perforations 13 and a thin film wiring board 14 to be projected by a plurality of keys 15, and the light will be scattered down again auxiliary reflector 11 of the light reflected upward through, so that the light emitting element 16 the light may be provided to improve utilization. 如上所述,即可使多个按键15产生发光的效果。 As described above, a plurality of keys 15 to produce light emission results. 惟,现有的发光键盘I具有如下所述的缺点: However, the conventional illuminated keyboard I has disadvantages as described below:

[0009] —、虽然反光板11可辅助多个导光点121向下散射的光线向上方反射,但现有发光键盘I的反光板11的材质可让光线穿透,因此一部分由多个导光点121向下散射的光线会穿透反光板11而造成光量的流失。 [0009] - although the light reflecting plate 11 may assist in guiding the plurality of light spots 121 is reflected upward scattering down, but the material conventional illuminated keyboard I reflector 11 may allow transmission of light, so in part by a plurality of guide spot 121 will penetrate downwardly scattered light reflector 11 caused by the loss of light quantity.

[0010] 二、请同步参阅图3,其为图2所示薄膜线路板的下层板的光路示意图。 [0010] Second, please refer to FIG. 3 the synchronization, the light path is a schematic view of a thin film wiring board lower plate 2 as shown in FIG. 由于第一电路图案1411设置于下层板141的上表面,且第一电路图案1411包括多条银胶线路14111,该些银胶线路14111具有将光线聚集及散射的性质,因此于发光元件16所提供的光线LI经由按键底板13的多个穿孔131而进入下层板141后,第一电路图案1411的银胶线路14111会呈现发亮的状态,如图示中光线L2,然而大部分银胶线路14111的设置并非是对应于多个按键15,因此原本应被使用于令多个按键15发光的光量会因银胶线路14211的特性而被消耗,也就是说,原本光线LI的光量中大部分应被按键15所获得,但因银胶线路14111的特性而使光线L2的光量被消耗,因此发光键盘I仅剩光线L3的光量可以利用,进而造成发光键盘I上的多个按键15有光量不足的情况。 Since the first circuit pattern 1411 is provided on the upper surface of the lower plate 141, and the first circuit pattern 1411 comprises a plurality of lines 14111 silver paste, silver paste the plurality of line 14111 has a light gathering and scattering properties, the light emitting element 16 so after LI light provided via a plurality of perforations 13 of the base plate 131 and the key 141 into the lower plate, a first circuit pattern of silver paste line 1411 14111 will show illuminated state, as shown in the light L2, however, most of the silver glue line 14111 is not provided corresponding to a plurality of keys 15, and therefore had to be used to make a plurality of keys 15 of luminous flux due to the characteristic line 14211 silver paste is consumed, i.e., the original amount of light rays in most LI key 15 should be obtained, but the characteristics of the silver paste 14111 line light amount of light L2 is consumed, thus emitting light L3 keyboard I remaining amount of light can be utilized, thus causing a plurality of keys 15 on the keyboard I light emission amount shortage situation.

[0011] 再者,请参阅图4,其为另一种现有发光键盘的结构剖面示意图。 [0011] In addition, please refer to FIG. 4, which is a schematic structural cross-sectional view of another conventional illuminated keyboard. 其中,本现有发光键盘大致类似于图1中所示之处,在此即不再予以赘述。 Wherein, the conventional illuminated keyboard is substantially similar to the sum shown in FIG. 1, namely, not be further described in. 而本现有发光键盘与前述现有发光键盘不同之处在于,发光元件96设置于薄膜线路板94的下层板941的侧边,且下层板941是由导光材质所制成,其中,下层板941上具有用以聚集且散射光线的多个导光点947,因此薄膜线路板94的下层板941即具有导光功能,而不再需要前述现有发光键盘中的反光板11以及导光板12,进而令发光键盘更加薄形化。 This is different from the conventional illuminated keyboard and that the conventional illuminated keyboard, the light emitting element 96 disposed on the side edge of the circuit board 94 of the lower plate 941 and lower plate 941 is made of a material of the light guide, wherein the lower layer having a plurality of light guide to collect and scatter light spot 947 on the plate 941, the thin film wiring board 941 i.e. lower plate 94 having a light guide function without the need of the conventional illuminated keyboard reflector 11 and the light guide plate 12, and thus to make more thin type light emitting keypad.

[0012] 然而,图4所示的发光键盘仍然具有前述现有发光键盘的两项缺点,并且由于薄膜线路板94具有分别用以供按键底板93的第一固定结构932以及第二固定结构933穿过其中的透孔945以及透孔946,使得薄膜线路板94的下层板941的导光作用不能连续,也就是说,当发光元件96所提供的光线遇到透孔945或透孔946时就会中断前进,因此,发光键盘9的发光效率大大减低。 [0012] However, the light emitting keypad of Figure 4 still has the disadvantage of two conventional illuminated keyboard, and since the film wiring board 94 having a button for each floor for the first fixing structure 93 and a second fixing structure 932 933 therethrough through hole 945 and the through hole 946, so that the film wiring board 94 of the lower plate 941 of the light guide effect can not be continuous, i.e., when the light emitting element 96 provided in the through hole encountered when the through hole 945 or 946 progress will be interrupted, and therefore, the luminous efficiency of 9 illuminated keyboard greatly reduced.

[0013] 故,现有的发光键盘1、9皆因光使用效率不佳而具有改善的空间。 [0013] Therefore, the conventional illuminated keyboard poor because the light use efficiency has room for improvement 1,9.
