In this embodiment, the first surface 31 faces the substrate 10 and is opposite to The second surface 36 is adjacent to the keys 20, but it is not limited. The light guide plate 30 can also be arranged such that the second surface 36 faces the substrate 10, and the second surface 36 is adjacent to the keys 20 relative to the first surface 31. Limitations.

如圖1與圖2所示，其中圖2為本發明發光鍵盤第一實施例之局部俯視圖。在本實施例中，導光板30的第一表面31包括多個發光區32以分別對應於基板10的多個組裝區11與多個按鍵20，其中各發光區32為第一表面31的局部表面區域（例如圖1中是以虛線框格區域標示多個發光區32）。As shown in Figs. 1 and 2, Fig. 2 is a partial top view of the first embodiment of the illuminated keyboard of the present invention. In this embodiment, the first surface 31 of the light guide plate 30 includes a plurality of light-emitting areas 32 to respectively correspond to the plurality of assembly areas 11 and the plurality of keys 20 of the substrate 10, wherein each light-emitting area 32 is a part of the first surface 31 The surface area (for example, in FIG. 1, a plurality of light-emitting areas 32 are marked with a dotted frame area).

如圖1與圖2所示，導光板30之第一表面31的每個發光區32皆可設有刻線圖案33。以其中一個發光區32為例，發光區32內的刻線圖案33為具有一定深度之多條刻線所構成之網格狀圖案，上述導光板30之刻線圖案33的製程可為但不限於以下方式，舉例來說，可利用雷射加工機或機械加工機在導光板30的製造模具上預先加工形成上述刻線圖案33，再透過熱壓或UV轉印等方式將刻線圖案33轉印至導光板30上。或者，亦可利用雷射加工機或機械加工機在導光板30的第一表面31上直接加工以形成上述刻線圖案33，此並不侷限。As shown in FIGS. 1 and 2, each light-emitting area 32 of the first surface 31 of the light guide plate 30 can be provided with a scribe pattern 33. Taking one of the light-emitting areas 32 as an example, the engraved line pattern 33 in the light-emitting area 32 is a grid pattern composed of multiple engraved lines with a certain depth. The manufacturing process of the engraved line pattern 33 of the light guide plate 30 can be, but not It is limited to the following methods. For example, a laser processing machine or a mechanical processing machine can be used to preprocess the scribed pattern 33 on the manufacturing mold of the light guide plate 30, and then the scribed pattern 33 can be formed by hot pressing or UV transfer. Transfer to the light guide plate 30. Alternatively, a laser processing machine or a mechanical processing machine can also be used to directly process the first surface 31 of the light guide plate 30 to form the aforementioned scribe pattern 33, which is not limited.

在一些實施例中，導光板30之第二表面36亦可包括分別對應於上述多個發光區32之多個局部區域，各局部區域也可設有上述刻線圖案33。In some embodiments, the second surface 36 of the light guide plate 30 may also include a plurality of partial regions respectively corresponding to the plurality of light-emitting regions 32, and each partial region may also be provided with the aforementioned scribe pattern 33.

上述發光區32內的刻線圖案33是用於萃取光能量，舉例來說，如圖1所示，光源40發出光線進入導光板30後，光線會在導光板30內反射傳遞，當部分光線傳遞至發光區32上的刻線圖案33時，刻線圖案33會改變光線的行進方向而使光線集中朝各按鍵20照射，達到光能量萃取之目的以提高發光效益。The engraved pattern 33 in the light-emitting area 32 is used to extract light energy. For example, as shown in FIG. When transferred to the engraved line pattern 33 on the light-emitting area 32, the engraved line pattern 33 will change the traveling direction of the light so that the light is concentrated on the keys 20, achieving the purpose of light energy extraction and improving the luminous efficiency.

在一些實施例中，刻線圖案33可包括多個刻線組34與至少一個格狀區域35。如圖1與圖2所示，在本實施例中，刻線圖案33包括多個刻線組34與多個格狀區域35，多個刻線組34彼此相交以形成上述多個格狀區域35，且多個格狀區域35對應於按鍵20之透光部12。藉此，每個格狀區域35都可由多條在不同方向延伸之刻線所圍繞而成，故可萃取來自不同角度的光線而利於光源40的配置並提高發光效益，且多個刻線組34是透過多條刻線彼此相交的方式形成格狀區域35，使加工設備在刻線圖案33的加工過程中不需頻繁進行加、減速，從而大幅減少加工時間以提高產能，其中刻線圖案33之刻線組34可有以下多種實施方式，此配合圖式說明如下。In some embodiments, the score line pattern 33 may include a plurality of score line groups 34 and at least one grid-shaped area 35. As shown in FIGS. 1 and 2, in this embodiment, the scribe line pattern 33 includes a plurality of scribe line groups 34 and a plurality of grid-shaped regions 35, and the plurality of scribe line groups 34 intersect each other to form the above-mentioned multiple grid-shaped regions. 35, and a plurality of grid-shaped regions 35 correspond to the light-transmitting portion 12 of the button 20. In this way, each grid area 35 can be surrounded by a plurality of engraved lines extending in different directions, so light from different angles can be extracted to facilitate the configuration of the light source 40 and improve the luminous efficiency, and a plurality of engraved line groups 34 is to form a grid-shaped area 35 through the way that multiple scribe lines intersect each other, so that the processing equipment does not need to accelerate and decelerate frequently during the processing of the scribed pattern 33, thereby greatly reducing the processing time and increasing the productivity. The engraved line group 34 of 33 can have the following multiple implementations, which are described in conjunction with the drawings as follows.

如圖2所示，於本實施例，刻線圖案33對應於基板10之透光部12的每個透光孔121皆設有多個刻線組34與多個格狀區域35，以其中一個透光孔121所對應之多個刻線組34為例，多個刻線組34包括彼此相交之第一刻線組341與第二刻線組342，其中第一刻線組341包括多條第一刻線3411，且各第一刻線3411為直線並朝第一方向延伸，第二刻線組342包括多條第二刻線3421，且各第二刻線3421為直線並朝第二方向延伸，且上述第一方向不同於第二方向，使第一刻線組341與第二刻線組342相交後能夠交織成網格狀圖案而形成多個格狀區域35。但本發明不以此為限，亦可依照需求調整刻線組34與格狀區域35的數量與位置。As shown in FIG. 2, in this embodiment, each light-transmitting hole 121 corresponding to the light-transmitting portion 12 of the substrate 10 is provided with a plurality of scribe-line groups 34 and a plurality of grid-like regions 35 in the scribed line pattern 33. A plurality of scribe line groups 34 corresponding to one light-transmitting hole 121 is taken as an example. The plurality of scribe line groups 34 includes a first scribe line group 341 and a second scribe line group 342 that intersect each other, wherein the first scribe line group 341 includes multiple There are two first scribe lines 3411, and each first scribe line 3411 is a straight line and extends in the first direction. The second scribe line group 342 includes a plurality of second scribe lines 3421, and each second scribe line 3421 is a straight line and faces the first It extends in two directions, and the first direction is different from the second direction, so that the first scribe line group 341 and the second scribe line group 342 can be interwoven into a grid pattern to form a plurality of grid-shaped regions 35 after intersecting. However, the present invention is not limited to this, and the number and positions of the engraved line group 34 and the grid-shaped area 35 can also be adjusted according to requirements.

如圖2所示，第一刻線組341之多條第一刻線3411可為彼此不相交（例如彼此平行）之直線，第二刻線組342之多條第二刻線3421亦可為彼此不相交（例如彼此平行）之直線。此外，上述各第一刻線3411延伸之第一方向與各第二刻線3421延伸之第二方向之間可具有一夾角，例如夾角可為銳角、鈍角或者直角，使第一刻線組341與第二刻線組342相交後能夠產生不同形狀之格狀區域35，例如格狀區域35可為方形、菱形、梯形或其他不規則形狀之四邊形。As shown in FIG. 2, the plurality of first scribe lines 3411 of the first scribe line group 341 may be straight lines that do not intersect each other (for example, parallel to each other), and the plurality of second scribe lines 3421 of the second scribe line group 342 may also be Straight lines that do not intersect each other (for example, parallel to each other). In addition, there may be an included angle between the first direction in which each first score line 3411 extends and the second direction in which each second score line 3421 extends. For example, the included angle may be an acute angle, an obtuse angle, or a right angle, so that the first score line group 341 After intersecting with the second scribe line group 342, grid-like regions 35 of different shapes can be generated. For example, the grid-like regions 35 can be square, rhombus, trapezoid or other irregularly shaped quadrilaterals.

如圖2所示，在本實施例中，第一刻線組341之各第一刻線3411為平行於X軸之刻線線段，第二刻線組342之各第二刻線3421為平行於Y軸之刻線線段而垂直於各第一刻線3411，使第一刻線組341與第二刻線組342相交後能夠形成方形的格狀區域35。藉此，由於第一刻線組341之各第一刻線3411與第二刻線組342之各第二刻線3421皆為獨立之直線線段而不具有迴轉區段及轉折線段，因此，加工設備可分別沿第一方向與第二方向一次加工完成各第一刻線3411與各第二刻線3421，而不需頻繁進行加、減速以迴轉或轉折，達到減少加工時間以大幅提高產能之效果。As shown in FIG. 2, in this embodiment, each first scribe line 3411 of the first scribe line group 341 is a scribe line segment parallel to the X axis, and each second scribe line 3421 of the second scribe line group 342 is parallel The engraved line segment on the Y axis is perpendicular to each first engraved line 3411, so that the first engraved line group 341 and the second engraved line group 342 can intersect to form a square grid-shaped area 35. As a result, since each first scribe line 3411 of the first scribe line group 341 and each second scribe line 3421 of the second scribe line group 342 are independent straight line segments without turning sections and turning line segments, the processing The equipment can process each first scribe line 3411 and each second scribe line 3421 in the first direction and the second direction respectively, without frequent acceleration, deceleration, rotation or turning, which can reduce the processing time and greatly increase the production capacity. Effect.

此外，如圖1與圖2所示，透過刻線圖案33包括沿X軸方向延伸之第一刻線3411以及沿Y軸方向延伸之第二刻線3421，使刻線圖案33能有效萃取來自不同角度的光線。一般平行於光線方向之刻線相較於垂直於光線方向之刻線來說，其光能量萃取率較差，因此，舉例來說，若光源40A的照射方向（即光線方向）為Y軸方向時（如圖2所示），即可透過沿X軸方向延伸之各第一刻線3411有效萃取光能量而達到預定的發光效果；若光源40B的照射方向為X軸方向時（如圖2所示），則可透過沿Y軸方向延伸之各第二刻線3421有效萃取光能量而達到預定的發光效果。由此可見，刻線圖案33之多個刻線組34能有效萃取來自不同角度的光線，使光源的設置方向、位置及數量不受限制而可根據產品的不同需求自由搭配選擇。In addition, as shown in FIGS. 1 and 2, the scribe line pattern 33 includes a first scribe line 3411 extending in the X-axis direction and a second scribe line 3421 extending in the Y-axis direction, so that the scribe line pattern 33 can effectively extract from Different angles of light. Generally, the light energy extraction rate of the engraved line parallel to the light direction is worse than that of the engraved line perpendicular to the light direction. Therefore, for example, if the irradiation direction of the light source 40A (that is, the light direction) is the Y-axis direction (As shown in Fig. 2), the light energy can be effectively extracted through each first scribe line 3411 extending along the X-axis direction to achieve the predetermined luminous effect; if the irradiation direction of the light source 40B is the X-axis direction (as shown in Fig. 2) Show), the second engraved lines 3421 extending along the Y-axis direction can effectively extract light energy to achieve the predetermined luminous effect. It can be seen that the multiple engraved line groups 34 of the engraved line pattern 33 can effectively extract light from different angles, so that the setting direction, position and quantity of the light source are not limited and can be freely matched and selected according to different requirements of the product.

此外，多個刻線組34透過彼此相交形成格狀區域35，可使多個刻線組34之交點處受到多次加工而增加交點處的深度，達到進一步提高光萃取能量之效果。In addition, the plurality of scribed line groups 34 form a grid-shaped area 35 by intersecting each other, so that the intersection of the plurality of scribed line groups 34 can be processed multiple times to increase the depth of the intersection, and achieve the effect of further increasing the light extraction energy.

在一些實施例中，刻線圖案33的各刻線（例如第一刻線3411與第二刻線3421）可具有不同的刻線深度或刻線寬度。舉例來說，刻線圖案33的各刻線的刻線深度越深或刻線寬度越寬，所能萃取到的光能量越多且亮度越高，各刻線的刻線深度或刻線寬度可根據光源照射方向進行調整，例如刻線圖案33中平行於光源照射方向之刻線的刻線深度或刻線寬度可大於垂直於光源照射方向之刻線的刻線深度或刻線寬度，以提高光萃取能量之效果，如此可使平行於光源照射方向之刻線萃取到的光能量同於垂直於光源照射方向之刻線萃取到的光能量，使刻線圖案33均勻發光。In some embodiments, each scribe line of the scribe line pattern 33 (for example, the first scribe line 3411 and the second scribe line 3421) may have different scribe line depths or scribe line widths. For example, the deeper the scribe line depth or the wider the scribe line width of the scribe line pattern 33, the more light energy that can be extracted and the higher the brightness, the scribe line depth or the scribe line width of each scribe line It can be adjusted according to the light source irradiation direction. For example, the scribe line depth or scribe line width of the scribe line parallel to the light source irradiation direction in the scribe line pattern 33 can be greater than the scribe line depth or width of the scribe line perpendicular to the light source irradiation direction. The effect of light extraction energy is improved, so that the light energy extracted by the engraved line parallel to the light source irradiation direction is the same as the light energy extracted by the engraved line perpendicular to the light source irradiation direction, so that the engraved line pattern 33 emits uniform light.

再如圖1與圖2所示，在本實施例中，各透光孔121所對應之第一刻線組341與第二刻線組342中的部分刻線可分別進一步沿第一方向與第二方向延伸以彼此相連，使刻線圖案33形成一完整的圖案並提高刻線圖案33的光萃取率。例如在本實施例中，各透光孔121所對應之第一刻線組341的其中二條第一刻線3411與第二刻線組342的其中二條第二刻線3421進一步延伸並彼此連接而形成一封閉圖形（在此封閉圖形呈方形），封閉圖形對應於發光區32之按鍵20具有的一字符21（在此字符21為字母A）。上述之封閉圖形可基於字符21的位置而圍繞字符21設置，且多個格狀區域35位於封閉圖形所圍繞的範圍內，即多個格狀區域35相較於封閉圖形更靠近字符21，以確保字符21的周圍能夠萃取到預定的光能量而達到需求亮度。As shown in FIGS. 1 and 2, in this embodiment, the first scribe line group 341 and the second scribe line group 342 corresponding to each light-transmitting hole 121 can be further along the first direction and The second direction extends to be connected to each other, so that the scribe line pattern 33 forms a complete pattern and improves the light extraction rate of the scribe line pattern 33.

上述各實施例之刻線圖案33可具有不同尺寸之格狀區域以有效增加光萃取效率。具體而言，導光板30之不同發光區32上方所對應之結構（例如按鍵20的結構、基板10之透光孔121的數量、位置或尺寸，或者連接件22的結構與尺寸）都不盡相同。舉例來說，不同發光區32所對應到的不同按鍵20上的字符面積、數量與位置不同，且部分按鍵20（例如Caps Lock鍵、Shift鍵、Ctrl鍵、Enter鍵或Backspace鍵）的長度也大於其他部份按鍵20（例如字母鍵與數字鍵）的長度，故不同長度之按鍵20所對應的連接件22之結構、位置或數量也會不同。基於此，透過各發光區32內的刻線圖案33具有朝不同方向延伸的多組刻線組（其包括多條刻線）以及不同尺寸與形狀之格狀區域，達到各發光區32之刻線圖案33能夠根據其上方所對應之結構進行調整與配置，可萃取來自不同方向之光線而更利於光源的配置，亦可有效增加光萃取效率及/或降低光萃取效率而提高發光鍵盤1之發光效益。The scribe pattern 33 of the above embodiments can have grid-like regions of different sizes to effectively increase the light extraction efficiency. Specifically, the corresponding structures above the different light-emitting areas 32 of the light guide plate 30 (such as the structure of the button 20, the number, position, or size of the light-transmitting holes 121 of the substrate 10, or the structure and size of the connecting member 22) are not exhaustive. same. For example, the areas, numbers, and positions of characters on different keys 20 corresponding to different light-emitting areas 32 are different, and the length of some keys 20 (such as Caps Lock, Shift, Ctrl, Enter, or Backspace) is also different. It is longer than the length of other parts of the keys 20 (such as letter keys and number keys), so the structure, position, or number of the connectors 22 corresponding to the keys 20 of different lengths will also be different. Based on this, the engraved line patterns 33 in each light-emitting area 32 have multiple sets of engraved lines (including multiple engraved lines) extending in different directions and grid-like regions of different sizes and shapes to achieve the engraving of each light-emitting area 32. The line pattern 33 can be adjusted and configured according to the corresponding structure above it. It can extract light from different directions and is more conducive to the configuration of the light source. It can also effectively increase the light extraction efficiency and/or reduce the light extraction efficiency to improve the light-emitting keyboard 1 Luminous benefits.

承上，如圖12所示，為本發明發光鍵盤第十一實施例之局部俯視圖，本實施例與圖2之實施例的差異至少在於，第一刻線組341之多條第一刻線3411之間的間距不同，第二刻線組342之多條第二刻線3421之間的間距也不同，使導光板30之發光區32內具有不同尺寸的格狀區域。例如在本實施例中，發光區32內之刻線圖案33包括多個第一格狀區域35G與多個第二格狀區域35H，各第一格狀區域35G的尺寸不同於各第二格狀區域35H的尺寸而第一格狀區域35G與第二格狀區域35H有不同的光萃取率。From the above, as shown in FIG. 12, it is a partial top view of the eleventh embodiment of the illuminated keyboard of the present invention. The difference between this embodiment and the embodiment of FIG. The spacing between the 3411 is different, and the spacing between the second scribe lines 3421 of the second scribe line group 342 is also different, so that the light-emitting area 32 of the light guide plate 30 has grid-like regions of different sizes. For example, in this embodiment, the engraved pattern 33 in the light-emitting area 32 includes a plurality of first grid-shaped regions 35G and a plurality of second grid-shaped regions 35H, and the size of each first grid-shaped region 35G is different from that of each second grid-shaped region 35G. The size of the grid-shaped region 35H is different, and the first grid-shaped region 35G and the second grid-shaped region 35H have different light extraction rates.

如圖12所示，刻線圖案33之格狀區域的尺寸變化可根據按鍵20的結構進行配置，例如在本實施例中，對應於發光區32之按鍵20具有一字符21（在此字符為字母A），多個第二格狀區域35H的尺寸大於多個第一格狀區域35G，且多個第二格狀區域35H相較於多個第一格狀區域35G鄰近字符21，進一步說，在同樣範圍面積內，第一格狀區域35G的數量或密度大於第二格狀區域35H的數量或密度，如此可提高按鍵20周圍（遠離字符21）的亮度，但此並不侷限，在一些實施例中，多個第一格狀區域35G亦可相較於多個第二格狀區域35H鄰近字符21，以提高字符21區域的亮度，舉例來說，對應於按鍵20上較小的字符21（例如逗號），發光區32內鄰近於字符21之格狀區域的數量或密度可進一步提高，對應於按鍵20無字符21但需要有暈光效果的無字區，發光區32內鄰近無字區之格狀區域的數量或密度則相對較低。As shown in FIG. 12, the size change of the grid area of the engraved pattern 33 can be configured according to the structure of the button 20. For example, in this embodiment, the button 20 corresponding to the light-emitting area 32 has a character 21 (here the character is Letter A), the size of the plurality of second grid-shaped regions 35H is larger than the plurality of first grid-shaped regions 35G, and the plurality of second grid-shaped regions 35H are adjacent to the characters 21 compared to the plurality of first grid-shaped regions 35G. In the same area, the number or density of the first grid-shaped area 35G is greater than the number or density of the second grid-shaped area 35H. This can increase the brightness around the button 20 (away from the character 21), but this is not limited. In some embodiments, the plurality of first grid-shaped areas 35G may also be adjacent to the characters 21 compared to the plurality of second grid-shaped areas 35H, so as to increase the brightness of the character 21 area, for example, corresponding to the smaller area on the button 20 For the character 21 (such as a comma), the number or density of the grid-shaped area adjacent to the character 21 in the light-emitting area 32 can be further increased, which corresponds to the non-character area where the button 20 has no characters 21 but needs a halo effect. The light-emitting area 32 is adjacent The number or density of grid-like areas in the wordless area is relatively low.

然而，上述實施例僅為舉例，在一些實施例中，多個第二格狀區域35H與多個第一格狀區域35G的分佈位置、大小、數量或密度亦可根據基板10之組裝區11的結構、連接件22之結構或者其他構件進行調整，以進一步提高發光鍵盤1之每個不同區域的光萃取率。However, the above-mentioned embodiments are only examples. In some embodiments, the distribution position, size, number, or density of the plurality of second grid-shaped regions 35H and the plurality of first grid-shaped regions 35G may also be based on the assembly area 11 of the substrate 10 The structure of the, the structure of the connector 22 or other components are adjusted to further increase the light extraction rate of each different area of the illuminated keyboard 1.

綜上，根據本發明實施例之發光鍵盤，透過導光板對應於每個按鍵之發光區內的刻線圖案呈網格狀圖案，即刻線圖案包括多個刻線組與至少一個格狀區域，多個刻線組彼此相交以形成格狀區域，且格狀區域對應於透光部，達到刻線圖案能有效萃取來自不同角度的光線而利於光源的配置並提高發光效益，且大幅減少加工設備的加工時間而提高產能。In summary, according to the light-emitting keyboard of the embodiment of the present invention, the engraved line pattern in the light-emitting area corresponding to each key through the light guide plate is a grid pattern, and the instant line pattern includes a plurality of engraved line groups and at least one grid-like area, Multiple engraved line groups intersect each other to form a grid-like area, and the grid-like area corresponds to the light-transmitting part, so that the engraved line pattern can effectively extract light from different angles, which facilitates the configuration of the light source and improves the luminous efficiency, and greatly reduces the processing equipment Processing time and increase productivity.
