Description
本創作相關於一種發光鍵盤，特別是相關於一種發光鍵盤之導光板裝置。The present invention relates to an illuminated keyboard, and more particularly to a light guide panel device associated with an illuminated keyboard.
近年來，發光鍵盤因其炫麗的視覺效果，以及能在光線較差的環境下正確識別按鍵的實用效果，而逐漸受到使用者的歡迎。發光鍵盤的內部具有導光板裝置，以將點光源轉成面光源的形式朝鍵帽出光。In recent years, the illuminated keyboard has been gradually welcomed by users due to its dazzling visual effects and the practical effect of correctly recognizing the keys in a poor light environment. The interior of the illuminated keyboard has a light guide plate device for emitting light into the keycap in the form of turning the point source into a surface light source.
為了空間利用的需求，導光板上會設置散熱孔、供其他元件穿設的機構孔……等的功能孔。然而，這些功能孔會影響導光板出光之特性。當光照射到功能孔的孔壁時，大部分的光線會從功能孔朝外折射出，使功能孔上的鍵帽之出光強度過強，尤其於功能孔的孔壁更為明顯，致使發光鍵盤的鍵帽出光不均勻。For the purpose of space utilization, functional holes such as heat dissipation holes, mechanism holes for other components, and the like are provided on the light guide plate. However, these functional holes affect the light-emitting characteristics of the light guide plate. When the light hits the hole wall of the function hole, most of the light will be refracted outward from the function hole, so that the light intensity of the key cap on the function hole is too strong, especially the hole wall of the function hole is more obvious, causing the light to be emitted. The keycap of the keyboard is uneven.
習知的導光板為了克服前述問題，提出二種解決方案：一、在功能孔的孔壁塗黑，以阻擋光線從功能孔的孔壁射出；二、在功能孔表面的周圍塗黑，以彌補功能孔過強之出光強度。而本創作亦針對前述問題而提出另一種解決方案。In order to overcome the aforementioned problems, the conventional light guide plate proposes two solutions: one, blackening the hole wall of the function hole to block light from being emitted from the hole wall of the function hole; second, blackening around the surface of the function hole, Make up for the strong light intensity of the function hole. This creation also proposes another solution to the aforementioned problems.
因此，本創作的目的即在提供一種發光鍵盤之導光板裝置，能克服功能孔導致鍵帽之出光強度過強而造成發光鍵盤的鍵帽出光不均勻的問題。Therefore, the purpose of the present invention is to provide a light guide plate device for an illuminated keyboard, which can overcome the problem that the function of the light hole of the keycap is too strong, resulting in uneven light emission of the keycap of the illuminated keyboard.

The light-incident surface 12 corresponds to a light source L to provide A function hole 2 is disposed on the light guide plate 1. The function hole 2 has a function hole 21 and a light-refractive surface 22, and the function hole 21 is formed up and down through the light-emitting surface 11 of the light guide plate 1, and the function hole 21 is provided. At least a part of the character portion C of the keycap K overlaps with each other in the up-and-down direction, and the light-refractive surface 22 is formed on a light-conducting transmission path between the function hole 21 and the light-incident surface 12, and the position of the character portion C is in the up-and-down direction. Offward from each other without overlapping, and at least a portion of the incident light of the light incident surface 12 with respect to the functional aperture 21 is refracted at the light refracting surface 22 to reduce the light intensity of the functional aperture 21 for the character portion C, wherein the light refracting surface 22 The hole is formed in the hole wall of the function hole 21 close to the light incident surface 12.
詳細而言，鍵帽K的字符部C的外型可以是文字、數字或符號，字符部C為發光鍵盤之外部可見的發光部位，而發光鍵盤之外部的其他部分為不透光。功能孔部2為導光板1上鄰近功能孔21之部位。其中，功能孔21可以是散熱孔、讓喇叭聲音通過的透聲孔、供其他元件穿設的機構孔、或其他功能之孔洞。而設置對應於導光板1入光面12的光源L為LED。In detail, the shape of the character portion C of the keycap K may be a character, a number or a symbol, the character portion C is a light-emitting portion visible outside the light-emitting keyboard, and the other portion outside the light-emitting keyboard is opaque. The functional hole portion 2 is a portion of the light guide plate 1 adjacent to the functional hole 21. The function hole 21 may be a heat dissipation hole, a sound transmission hole through which the horn sound passes, a mechanism hole through which other components are pierced, or a hole of other functions. The light source L corresponding to the light incident surface 12 of the light guide plate 1 is provided as an LED.
如第1圖所示，在本實施例中，字符部C為A字形，功能孔21為橢圓形的貫通孔，功能孔21與鍵帽K的字符部C於上下方向為部分重疊，光折射面22為功能孔21靠近光源L的弧形壁面。功能孔21於字符部C的正下方往入光面11沿伸，光折射面22為超出字符部C之範圍，以使從光折射面22向上出射的光線不會從字符部C穿透出鍵帽，從而避免字符部C之出光強度過強。而在其他實施例中，功能孔21也可以是圓形孔、多邊形孔、條狀孔，甚至是不規則形的孔。As shown in Fig. 1, in the present embodiment, the character portion C has an A-shape, and the function hole 21 is an elliptical through hole.

The function hole 21 extends toward the light-incident surface 11 directly below the character portion C, and the light-refractive surface 22 is beyond the range of the character portion C so that the light emitted upward from the light-refractive surface 22 does not penetrate from the character portion C. The key cap prevents the light intensity of the character portion C from being too strong. In other embodiments, the functional apertures 21 can also be circular apertures, polygonal apertures, strip apertures, or even irregularly shaped apertures.
如第2圖所示，依據本創作的第二實施例的發光鍵盤之導光板裝置100a，其結構與第一實施例的發光鍵盤之導光板裝置100大致相同，差別在於：功能孔部2在功能孔21與入光面12之間的導光傳遞路徑上具有一出光孔23，光折射面22係形成在出光孔23靠近入光面12的孔壁。出光孔23為條狀孔，上下貫通形成於導光板1之出光面11，以使出光孔23的光折射面22適當地阻擋光線通往功能孔21的導光傳遞路徑，而具有降低字符部C出光強度的效果。而在其他實施例中，出光孔23可以是一凹孔而未貫穿導光板1，以使光折射面22部分地阻擋光線的導光傳遞路徑，降低字符部C出光強度之效果為依據出光孔23之深度而定。當然，出光孔23也可以是一橢圓孔、圓形孔、多邊形孔，甚至是不規則形的孔。在其他實施例中，光折射面22是同時形成在出光孔23靠近入光面12的孔壁以及形成在功能孔21靠近該入光面12的孔壁。As shown in FIG. 2, the light guide plate device 100a of the illuminated keyboard according to the second embodiment of the present invention has substantially the same structure as the light guide plate device 100 of the illuminated keyboard of the first embodiment, with the difference that the functional hole portion 2 is An optical light transmission hole 23 is formed on the light guiding transmission path between the functional hole 21 and the light incident surface 12, and the light refractive surface 22 is formed on the wall of the light exiting hole 23 close to the light incident surface 12. The light exit hole 23 is a strip-shaped hole, and is formed vertically on the light-emitting surface 11 of the light guide plate 1 so that the light-refractive surface 22 of the light-emitting hole 23 appropriately blocks the light-guiding path of the light-guiding opening to the function hole 21, and has a reduced character portion. C light intensity effect. In other embodiments, the light exit hole 23 may be a recessed hole and does not penetrate the light guide plate 1 so that the light refracting surface 22 partially blocks the light guiding transmission path of the light, and the effect of reducing the light intensity of the character portion C is based on the light exit hole. The depth of 23 depends. Of course, the light exit hole 23 can also be an elliptical hole, a circular hole, a polygonal hole, or even an irregular shape. In other embodiments, the light-refractive surface 22 is formed on the wall of the hole near the light-incident surface 12 of the light-emitting aperture 23 and the wall of the hole formed in the functional aperture 21 adjacent to the light-incident surface 12.
藉由上述結構，功能孔21孔壁的光折射面22或出光孔23孔壁的光折射面22是與字符部C的位置於上下方向上互相偏離而不重疊，以使從光折射面22向上出射的光線不會從字符部C穿透出鍵帽K，以降低功能孔21對於字符部C之出光強度。With the above configuration, the light-refractive surface 22 of the hole wall of the functional hole 21 or the light-refractive surface 22 of the hole wall of the light-emitting hole 23 is offset from the position of the character portion C in the up-and-down direction without overlapping so that the light-refractive surface 22 is removed from the light-refractive surface 22 The light that is emitted upward does not penetrate the key cap K from the character portion C to lower the light intensity of the functional hole 21 with respect to the character portion C.
以上之敘述以及說明僅為本創作之較佳實施例之說明，對於此項技術具有通常知識者當可依據以下所界定申請專利範圍以及上述之說明而作其他之修改，惟此些修改仍應是為本創作之創作精神而在本創作之權利範圍中。The above description and description are only illustrative of the preferred embodiments of the present invention, and those having ordinary skill in the art may make other modifications in accordance with the scope of the patent application as defined below and the above description, but such modifications are still It is the creative spirit of this creation and is within the scope of this creation.
