Description

導光板及發光鍵盤Light guide plate and illuminated keyboard

本發明是有關於一種鍵盤,特別是指一種發光鍵盤。The invention relates to a keyboard, in particular to a light-emitting keyboard.

參閱圖1,為本發明申請權人所研發且已提申為中華民國證書號第M525536號專利案的一種發光鍵盤的導光板9,該導光板9由複數列導光塊91所組成,各導光塊91具有複數將自身分隔出複數導光部911的光導阻絕空間912,及複數分別對應該等導光部911且分別供一光源(圖未示)設置的的光源設置空間913。該等導光部911是分別對應該發光鍵盤的複數字鍵(圖未示),且該等光導阻絕空間912用以有效將各光源所發出的光限制於各導光部911內傳導,藉此使得各導光部911的發光亮度是由單一光源控制,而不受其餘光源的影響,從而讓該等導光部911的發光亮度是均勻一致,趨近於各光源的發光亮度,進而使得該等字鍵的透光部的發光亮度均勻一致。Referring to FIG. 1, a light guide plate 9 of a light-emitting keyboard, which is developed by the applicant of the present invention and has been applied for as a patent of the Republic of China No. M525536. The light guide plate 9 is composed of a plurality of light guide blocks 91. The light guide block 91 has a plurality of light guide blocking spaces 912 that separate itself from the plurality of light guide sections 911, and a plurality of light source installation spaces 913 corresponding to the light guide sections 911 and provided for a light source (not shown). The light-guiding portions 911 are complex numeric keys (not shown) corresponding to the illuminated keyboard, and the light-guiding blocking spaces 912 are used to effectively limit the light emitted by each light source to the conduction in the light-guiding portions 911. This allows the light emission brightness of each light guide portion 911 to be controlled by a single light source without being affected by other light sources, so that the light emission brightness of the light guide portions 911 is uniform and close to the light emission brightness of each light source, thereby making The luminous brightness of the light-transmitting portions of the word keys is uniform.

但上述導光板9的該等光導阻絕空間912僅能防止各光源所發出的光線傳導至非所對應的導光部911,而各光源所發出的光線還是會由所對應的導光塊91的周面側漏,使得各導光部911對於各字鍵發射的光亮度會有所減弱,從而降低各光源的光利用率。另外,該導光板9雖然可以透過一外框件(圖未示)連接該六列導光塊91,但該等導光塊91間還是具有間隙,以及各導光塊91具有該等光導阻絕空間912,使得該導光板9整體的結構強度有所不足,也就是各導光塊91容易受外力彎曲,造成該導光板9整體是翹曲不平,從而影響與該發光鍵盤其他元件的組裝密合度,因此上述導光板9的缺點有待改善。However, the light guide blocking spaces 912 of the light guide plate 9 described above can only prevent the light emitted by each light source from being transmitted to the non-corresponding light guide portion 911, and the light emitted by each light source will still be transmitted by the corresponding light guide block 91. The peripheral side leakage causes the light guides 911 to reduce the brightness of the light emitted by each word key, thereby reducing the light utilization efficiency of each light source. In addition, although the light guide plate 9 can be connected to the six-row light guide blocks 91 through an outer frame member (not shown), there is a gap between the light guide blocks 91 and each light guide block 91 has the light guide block The space 912 makes the overall structural strength of the light guide plate 9 inadequate, that is, the light guide blocks 91 are easily bent by external forces, causing the entire light guide plate 9 to be warped, which affects the assembly tightness with other components of the light-emitting keyboard. The degree of convergence is therefore to be improved.

因此,本發明之目的,即在提供一種至少克服先前技術所述缺點的發光鍵盤。It is therefore an object of the present invention to provide a light-emitting keyboard that overcomes at least the disadvantages described in the prior art.

另外,在該導光板5能將各光源72所發出的光線限制僅能由各導光塊541的頂、底面向外射出的情況下,本發明發光鍵盤則可省略設置於該鍵盤模組100與該導光板5間的該遮光片4,且也可省略設置於該導光板5與該發光單元7的該電路板71間的反光件6,而讓不透光的該電路板71緊貼於該導光板5的該底面52,且該電路板71的周緣是延伸至該遮光板體53的該外圍邊框530而貼合於該外圍邊框530,使得該電路板71也能達到大致相同於該反光件6的反光功效。也就是說,該導光板5使得該背光模組200整體板厚能有效降低。In addition, in the case where the light guide plate 5 can limit the light emitted by each light source 72 to only be emitted from the top and bottom faces of each light guide block 541, the light-emitting keyboard of the present invention can be omitted from the keyboard module 100. The light shielding sheet 4 between the light guide plate 5 and the light guide plate 5 can be omitted, and the light reflecting member 6 provided between the light guide plate 5 and the circuit board 71 of the light emitting unit 7 can be omitted, so that the circuit board 71 that is opaque can be closely attached. On the bottom surface 52 of the light guide plate 5, and the periphery of the circuit board 71 is extended to the peripheral frame 530 of the light shielding plate body 53 and is attached to the peripheral frame 530, so that the circuit board 71 can also reach approximately the same as The reflective effect of the reflective member 6. That is, the light guide plate 5 enables the overall thickness of the backlight module 200 to be effectively reduced.

綜上所述,本發明發光鍵盤確實能達成本發明之目的。In summary, the illuminated keyboard of the present invention can indeed achieve the purpose of the present invention.

惟以上所述者,僅為本發明之實施例而已,當不能以此限定本發明實施之範圍,凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
