Description
本發明係有關一種局部增亮的發光鍵盤，尤指一種將鍵帽亮度提高以便於辨識的發光鍵盤。 The invention relates to a locally brightened illuminated keyboard, in particular to an illuminated keyboard which improves the brightness of the keycap for easy identification.
在現今科技資訊的時代，電腦已成為人們不可或缺的必需品，並與人們的生活息息相關，各行各業也都需仰賴電腦來輔助作業，無論是桌上型電腦或筆記型電腦等，其使用的領域與時機相當廣泛，且在任何環境下皆有可能使用，但於低亮度或黑暗環境下，因為光線不足導致無法準確敲擊鍵盤作為訊號之輸出。 In the age of today's scientific and technological information, computers have become an indispensable necessity for people, and they are closely related to people's lives. All walks of life also rely on computers to assist in their work, whether it is a desktop computer or a notebook computer. The field and timing are quite extensive and can be used in any environment, but in low-light or dark environments, the keyboard cannot be accurately tapped as a signal output due to insufficient light.
為解決此一問題目前已有多種發光鍵盤專利問世，如美國第6179432、6199996、6284988、6322229、6554442號專利案及台灣第438035、465777、468833、509955、516671、535385、570235、1242737號專利案所示，上述專利案均揭露一種發光鍵盤，主要係將一發光片設置於鍵盤內部，使發光片對鍵帽發出光線而便於使用者於光線不足或黑暗的環境中操作鍵盤。 In order to solve this problem, a variety of illuminating keyboard patents have been published, such as the US Patent Nos. 6169432, 6199996, 6284988, 6322229, 6554442 and Taiwan 438035, 465777, 468833, 509955, 516671, 535385, 570235, 1242737. As shown in the above, all of the above patents disclose an illuminating keyboard, which mainly comprises a illuminating sheet disposed inside the keyboard, so that the illuminating sheet emits light to the keycap, so that the user can operate the keyboard in an environment with insufficient light or darkness.
但是，在上述各專利技術文獻中均訴求鍵盤內之發光元件與鍵帽之間僅有彈性體及連動機構阻隔，而各專利中大多將鍵帽、彈性體及連動機構以透光材料製成(部分專利是將鍵帽設計為非透光材料、但鍵帽上之字元符號為透光材料製成)，讓發光片整片式射出光源時，鍵盤是呈現均勻背光型態，由於使用者在操作發光鍵盤之環境多為光線不足、較為黑暗處，例如飛機上、車上等低 亮度環境，但鍵盤整片均勻發光，將造成整體亮度過強而影響周圍其他人，且在此低亮度環境中，使用者對鍵盤可視能力本就降低許多，若整片均勻發亮，使用者根本難以辨識每一鍵帽上之字元符號，即使該字元符號以不透光材料製成，或者鍵帽為不透光材料而字元符號為透光材料，也會因相鄰鍵帽之間隙所射出之光源干擾效應而造成辨識不易之困難度，對不熟悉無法確實記憶鍵帽字元符號者，將產生敲擊錯誤而輸出錯誤指令訊號的問題。 However, in each of the above patent documents, it is claimed that only the elastic body and the interlocking mechanism are blocked between the light-emitting element and the key cap in the keyboard, and in most patents, the key cap, the elastic body and the linkage mechanism are made of a light-transmitting material. (Some patents are designed to design a keycap as a non-transparent material, but the symbol on the keycap is made of a light-transmissive material.) When the illuminating sheet is fired out of the light source, the keyboard exhibits a uniform backlight pattern due to the use. The environment in which the illuminated keyboard is operated is mostly low in light and dark, such as on the plane, on the car, etc. Brightness environment, but the whole keyboard is evenly illuminated, which will cause the overall brightness to be too strong and affect other people around. In this low-brightness environment, the user's visual ability to the keyboard is much lower. If the whole piece is evenly lit, the user It is difficult to identify the symbol on each keycap, even if the symbol is made of opaque material, or the keycap is opaque and the symbol is light transmissive, it will be adjacent to the keycap. The interference effect of the light source emitted by the gap causes the difficulty of identification. For those who are unfamiliar with the keycap symbol, the tap error may be generated and the error command signal may be output.
本發明的主要目的，在於解決上述之缺失，藉此增加鍵帽的亮度，以便於使用者辨識鍵帽。 The main object of the present invention is to solve the above-mentioned deficiency, thereby increasing the brightness of the keycap so that the user can recognize the keycap.

In addition to the single side of 50, it can be disposed on both sides of the light guide plate 50 as shown in FIG. 3, for example, the light guide plate 50 first forms a hole with a small aperture, and then the hole is enlarged by a device with a large outer diameter. The through hole 52 is pressed toward the both sides of the light guide plate 50 to form the concentrating portion 51 on both sides of the light guide plate 50.
此外，該導光板50另可設置於該電路板60之下，如『圖4至圖6』所示，與前述實施例不同的地方在於該導光板50設置的位置不同，圖4至圖6的實施例中，該導光板50界於該電路板60與該底板70之間，因此不需設置通孔52來容置該彈性體30，該發光元件80的光源經由該導光板50並穿過該電路板60(可為薄膜電路板)而傳導至鍵帽10；而該導光板50的聚光部51於此實施例中係形成一凸柱的態樣，且該聚光部51亦可設置於該導光板50的單側或兩側；例如圖4的實施例將該聚光部51係設置於該導光板50的下側，而圖5的實施例係將該聚光部51設置於該導光板50的上側，另外，在圖6中，將聚光部51設置於該導光板50的兩側；因此，本發明並不限定該導光板50設置的位置，可設置於該基板40與該電路板60之間，亦可設置於該電路板60與該底板70之間，重要的是該導光板50於 預定局部位置藉該聚光部51而增加發光亮度。 In addition, the light guide plate 50 may be disposed under the circuit board 60, as shown in FIG. 4 to FIG. 6, which is different from the foregoing embodiment in that the position of the light guide plate 50 is different, and FIG. 4 to FIG. 6 In the embodiment, the light guide plate 50 is disposed between the circuit board 60 and the bottom plate 70. Therefore, the through hole 52 is not required to accommodate the elastic body 30. The light source of the light emitting element 80 is pierced through the light guide plate 50. The circuit board 60 (which may be a thin film circuit board) is transmitted to the keycap 10; and the concentrating portion 51 of the light guide plate 50 forms a stud in this embodiment, and the concentrating portion 51 is also It can be disposed on one side or both sides of the light guide plate 50. For example, in the embodiment of FIG. 4, the concentrating portion 51 is disposed on the lower side of the light guide plate 50, and the embodiment of FIG. 5 is the concentrating portion 51. It is disposed on the upper side of the light guide plate 50. In addition, in FIG. 6, the concentrating portion 51 is disposed on both sides of the light guide plate 50. Therefore, the present invention does not limit the position where the light guide plate 50 is disposed, and may be disposed on the light concentrating plate 50. The substrate 40 and the circuit board 60 may be disposed between the circuit board 60 and the bottom plate 70. What is important is that the light guide plate 50 is The predetermined local position is used to increase the luminance of the light by the concentrating portion 51.
除了透過該聚光部51來增加發光亮度之外，當該導光板50設置於該基板40與該電路板60之間時，可如『圖7及圖8』所示調整該導光板50通孔52、53的態樣，以控制通孔52、53內光源反射的效果，其中，本發明中導光板50通孔52、53的態樣係由前述成形機具的外型而定，如圖7所示，若成型機具的外徑為圓形，則該導光板50便會產生圓形且孔壁較為光滑的通孔52，而使光源傳導至通孔52內以後，較不易產生反射的效果；如圖8，如成型機具的外徑非圓形，則導光板50的通孔53則非圓形，且可因應成型機具的外徑而形成凹凸不平、或不規則的孔壁，使光源傳導至通孔53內以後，因孔壁形成凹部與凸部的結構而產生多次反射，可再次增加導光亮度；本發明除了可藉由該聚光部51增加導光亮度之外，更可透過通孔52、53孔壁的形式達到光源導出時反射的效果，可再進一步的增加導光亮度。 When the light guide plate 50 is disposed between the substrate 40 and the circuit board 60, the light guide plate 50 can be adjusted as shown in FIG. 7 and FIG. 8 . The aspect of the holes 52, 53 is used to control the reflection of the light source in the through holes 52, 53. The state of the through holes 52, 53 of the light guide plate 50 in the present invention is determined by the appearance of the forming tool, as shown in the figure. 7, if the outer diameter of the forming tool is circular, the light guide plate 50 will have a circular through hole 52 with a relatively smooth hole wall, and after the light source is conducted into the through hole 52, the reflection is less likely to occur. The effect; as shown in FIG. 8, if the outer diameter of the forming tool is non-circular, the through hole 53 of the light guide plate 50 is non-circular, and the uneven wall or the irregular hole wall can be formed according to the outer diameter of the forming tool. After the light source is conducted into the through hole 53 , multiple reflections are generated due to the structure of the concave portion and the convex portion of the hole wall, and the light guiding brightness can be increased again. In addition to the light guiding brightness of the light collecting portion 51 can be increased by the present invention, The effect of reflection when the light source is derived can be achieved through the holes of the through holes 52 and 53, which can be further increased. Add light guide brightness.
綜上所述，本發明主要係於該導光板50的預定局部位置上設有一聚光部51，令該導光板50以該聚光部51於鍵盤部預定局部位置提供較強亮度發光效果，且如『圖9』所示，預定局部位置為對應鍵帽10的位置時，藉由上述方案將使各鍵帽10的亮度提升，以便於使用者區隔出各鍵帽10的位置，藉此改善傳統發光鍵盤均勻發光造成鍵帽位置不易辨識之缺失。 In summary, the present invention is mainly provided with a concentrating portion 51 at a predetermined partial position of the light guide plate 50, so that the light guiding plate 50 provides a strong brightness illuminating effect at a predetermined local position of the concentrating portion 51 at the keyboard portion. And as shown in FIG. 9, when the predetermined partial position is the position corresponding to the keycap 10, the brightness of each keycap 10 is raised by the above solution, so that the user can separate the positions of the keycaps 10, This improves the lack of uniform recognition of the position of the keycap by the uniform illumination of the conventional illuminated keyboard.
經由以上可知，本發明相較於習知技術達到的有益效果在於提升發光鍵盤操作輸入的準確率。 From the above, it can be seen that the advantageous effects achieved by the present invention over conventional techniques are to improve the accuracy of the operational input of the illuminated keyboard.
