Description
本發明是有關於一種導光元件以及光源模組，且特別是有關於一種能產生良好的局部視覺外觀(local visual appearance)的導光元件以及光源模組。The present invention relates to a light guiding element and a light source module, and more particularly to a light guiding element and a light source module capable of producing a good local visual appearance.
近年來，隨著照明技術的進步，使用導光元件搭配光源的光源模組已逐漸應用在許多電子產品與照明燈具中。In recent years, with the advancement of lighting technology, light source modules using light guiding elements and light sources have been gradually applied in many electronic products and lighting fixtures.
上述的光源模組可應用在鍵盤、筆記型電腦、手機、顯示器等。舉例而言，傳統的鍵盤無法發光。利用在鍵盤的內部設置光源模組，可使得發光鍵盤能在黑暗的環境中被使用。然而，經過每個鍵帽而出射的光線強度不一，將產生每個鍵帽之間產生不同的發光視覺效果。The above light source module can be applied to a keyboard, a notebook computer, a mobile phone, a display, and the like. For example, a traditional keyboard cannot shine. By using a light source module inside the keyboard, the illuminated keyboard can be used in a dark environment. However, the intensity of the light exiting through each of the keycaps will produce a different illuminating visual effect between each of the keycaps.
另外，光源模組中的導光元件可具有特定形狀的導光圖案，用以顯示產品的商標圖形。這樣的光源模組可設置在筆記型電腦的背蓋。利用發光視覺效果來顯示筆記型電腦的品牌，進而提昇筆記型電腦的質感。上述的光源模組也可直接使用來作為廣告告示牌。然而，上述習知的光源模組中，導光元件的表面通常是光滑的，因此，導光元件容易滑動，而常常導致組裝不良。再者，導光元件的導光圖案以及導光圖案之外的區域都是光滑面，光源所提供的光線的出光率幾乎相同，因此，光線同時從導光圖案以及導光圖案之外的區域出射，導致無法清晰地顯示導光圖案。In addition, the light guiding element in the light source module may have a light guiding pattern of a specific shape for displaying a trademark graphic of the product. Such a light source module can be disposed on the back cover of the notebook. Use the illuminating visuals to display the brand of the notebook, which in turn enhances the texture of the notebook. The above light source module can also be directly used as an advertising sign. However, in the above conventional light source module, the surface of the light guiding member is generally smooth, and therefore, the light guiding member is apt to slide, often resulting in poor assembly. Furthermore, the light guiding pattern of the light guiding element and the area other than the light guiding pattern are smooth surfaces, and the light output rate of the light source is almost the same, so that the light is simultaneously from the light guiding pattern and the area other than the light guiding pattern. The light is emitted so that the light guiding pattern cannot be clearly displayed.
有鑑於此，本發明提供一種導光元件，能夠增加導光元件的摩擦力而避免組裝不良的問題，並且，還能清晰地顯示導光圖案。In view of the above, the present invention provides a light guiding element capable of increasing the frictional force of the light guiding element to avoid the problem of assembly failure, and also clearly displaying the light guiding pattern.
本發明提供一種光源模組，具有上述的導光元件，能夠清晰地顯示導光元件的導光圖案。The present invention provides a light source module having the above-described light guiding element capable of clearly displaying a light guiding pattern of a light guiding element.
基於上述，本發明提出一種導光元件，包括：至少一第一導光圖案、粗糙圖案以及空白圖案。粗糙圖案位於第一導光圖案以外的區域。至少部分空白圖案位於第一導光圖案之外，且空白圖案位於第一導光圖案與粗糙圖案之間。Based on the above, the present invention provides a light guiding element comprising: at least one first light guiding pattern, a rough pattern, and a blank pattern. The rough pattern is located in an area other than the first light guiding pattern. At least part of the blank pattern is located outside the first light guiding pattern, and the blank pattern is located between the first light guiding pattern and the rough pattern.
本發明還提出一種光源模組，包括：導光元件與光源。導光元件，包括：至少一第一導光圖案、粗糙圖案以及空白圖案。粗糙圖案位於第一導光圖案以外的區域。至少部分空白圖案位於第一導光圖案之外，且空白圖案位於第一導光圖案與粗糙圖案之間。光源設置在導光元件的入光面的一側。The invention also provides a light source module, comprising: a light guiding element and a light source. The light guiding element comprises: at least one first light guiding pattern, a rough pattern and a blank pattern. The rough pattern is located in an area other than the first light guiding pattern. At least part of the blank pattern is located outside the first light guiding pattern, and the blank pattern is located between the first light guiding pattern and the rough pattern. The light source is disposed on one side of the light incident surface of the light guiding element.
在本發明的一實施例中，上述的空白圖案圍繞第一導光圖案。In an embodiment of the invention, the blank pattern surrounds the first light guiding pattern.
在本發明的一實施例中，上述的空白圖案由第一導光圖案的周圍延伸而出。In an embodiment of the invention, the blank pattern extends from the periphery of the first light guiding pattern.
在本發明的一實施例中，上述的導光元件更包括：第二導光圖案，相鄰於第一導光圖案，其中，空白圖案圍繞第一導光圖案與第二導光圖案、且設置於第一導光圖案與第二導光圖案之間。In an embodiment of the invention, the light guiding element further includes: a second light guiding pattern adjacent to the first light guiding pattern, wherein the blank pattern surrounds the first light guiding pattern and the second light guiding pattern, and The first light guiding pattern and the second light guiding pattern are disposed.
在本發明的一實施例中，上述的導光元件更包括：第三導光圖案，相鄰於導光元件的邊界，且第三導光圖案與導光元件的邊界之間不具有粗糙圖案。In an embodiment of the invention, the light guiding element further includes: a third light guiding pattern adjacent to a boundary of the light guiding element, and the third light guiding pattern and the boundary of the light guiding element have no rough pattern .
在本發明的一實施例中，上述的粗糙圖案的深度小於第一導光圖案的深度。In an embodiment of the invention, the roughness of the rough pattern is smaller than the depth of the first light guiding pattern.
在本發明的一實施例中，上述的粗糙圖案的出光率小於第一導光圖案的出光率。In an embodiment of the invention, the light extraction rate of the rough pattern is smaller than the light extraction rate of the first light guiding pattern.
基於上述，本發明的導光元件在第一導光圖案之外的區域設置粗糙圖案，可提昇導光元件的整體摩擦力，可避免導光元件在組裝時產生滑動。另外，利用粗糙圖案來明顯區分出第一導光圖案，而能夠清晰地顯示第一導光圖案，產生良好的局部視覺外觀。再者，藉由設置於第一導光圖案與粗糙圖案之間的空白圖案，而能夠產生更細緻的視覺效果，進一步強化第一導光圖案與粗糙圖案之間的視覺差異。使第一導光圖案的發光輪廓更為清晰與銳利。Based on the above, the light guiding element of the present invention is provided with a rough pattern in a region other than the first light guiding pattern, which can improve the overall frictional force of the light guiding element, and can prevent the light guiding element from slipping during assembly. In addition, the first light guiding pattern is clearly distinguished by the rough pattern, and the first light guiding pattern can be clearly displayed, resulting in a good partial visual appearance. Furthermore, by providing a blank pattern between the first light guiding pattern and the rough pattern, a more detailed visual effect can be produced, and the visual difference between the first light guiding pattern and the rough pattern is further enhanced. The light guiding profile of the first light guiding pattern is made clearer and sharper.
為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖1為本發明的一實施例的導光元件的示意圖。請參照圖1，導光元件100包括：至少一第一導光圖案110、粗糙圖案120以及空白圖案130。粗糙圖案120位於第一導光圖案110以外的區域。至少部分的空白圖案130位於第一導光圖案110之外，且空白圖案130位於第一導光圖案110與粗糙圖案120之間。1 is a schematic view of a light guiding element according to an embodiment of the present invention. Referring to FIG. 1 , the light guiding component 100 includes at least one first light guiding pattern 110 , a rough pattern 120 , and a blank pattern 130 . The roughness pattern 120 is located in a region other than the first light guiding pattern 110. At least a portion of the blank pattern 130 is located outside the first light guiding pattern 110, and the blank pattern 130 is located between the first light guiding pattern 110 and the roughness pattern 120.
在圖1中的實施例，繪示的是空白圖案130圍繞第一導光圖案110，然而，實際上，空白圖案130也可部分地設置在第一導光圖案110之外，即，空白圖案130可部分地圍繞第一導光圖案110。In the embodiment of FIG. 1, the blank pattern 130 is illustrated as surrounding the first light guiding pattern 110. However, in practice, the blank pattern 130 may also be partially disposed outside the first light guiding pattern 110, that is, a blank pattern. 130 may partially surround the first light guiding pattern 110.
可注意到，第一導光圖案110以外的區域設置了粗糙圖案120，該粗糙圖案120可以提昇導光元件100整體的摩擦力，而防止因導光元件100之滑動而組裝不良的問題。再者，粗糙圖案120的發光效果與第一導光圖案110的發光效果是不同的，例如，粗糙圖案120的出光率可小於第一導光圖案110的出光率。如此一來，可明顯區分第一導光圖案110與粗糙圖案120，亦即，能夠清晰地顯示第一導光圖案110，產生良好的局部視覺外觀。It can be noted that a region other than the first light guiding pattern 110 is provided with a rough pattern 120 which can raise the frictional force of the entire light guiding element 100 and prevent the assembly failure due to the sliding of the light guiding element 100. Moreover, the light-emitting effect of the rough pattern 120 is different from the light-emitting effect of the first light guiding pattern 110. For example, the light-emitting rate of the rough pattern 120 may be smaller than the light-emitting rate of the first light guiding pattern 110. In this way, the first light guiding pattern 110 and the roughness pattern 120 can be clearly distinguished, that is, the first light guiding pattern 110 can be clearly displayed, resulting in a good partial visual appearance.
粗糙圖案120例如是利用表面具有圖案的滾輪(未繪示)在導光元件100的表面的局部區域進行滾壓摩擦時而形成的，亦即，粗糙圖案120的表面粗糙度會不同於第一導光圖案110的表面粗糙度。The rough pattern 120 is formed by, for example, rolling a surface of a surface of the light guiding element 100 by a roller (not shown) having a pattern on the surface, that is, the surface roughness of the rough pattern 120 is different from that of the first The surface roughness of the light guiding pattern 110.
更詳細而言，請再參照圖1，粗糙圖案120的深度可小於第一導光圖案110的深度。換言之，第一導光圖案110從導光元件100的表面突出的高度會大於粗糙圖案120從導光元件100的表面突出的高度；或者，第一導光圖案110從導光元件100的表面內凹的高度會大於粗糙圖案120從導光元件100的表面內凹的高度。如此，可使第一導光圖案110呈現更立體的視覺效果。In more detail, referring again to FIG. 1 , the depth of the roughness pattern 120 may be less than the depth of the first light guiding pattern 110 . In other words, the height of the first light guiding pattern 110 protruding from the surface of the light guiding element 100 may be greater than the height of the rough pattern 120 protruding from the surface of the light guiding element 100; or the first light guiding pattern 110 may be from the surface of the light guiding element 100. The height of the recess may be greater than the height of the rough pattern 120 from the surface of the light guiding element 100. In this way, the first light guiding pattern 110 can be made to have a more stereoscopic visual effect.
再者，粗糙圖案120的粗糙度是可以進行調整的，圖1中以網點來表示粗糙圖案120。但是實際上，粗糙圖案120的粗糙度可以形成為肉眼與手的觸感難以辨認的狀態，只要粗糙圖案120在微觀的結構上與第一導光圖案110能夠造成光學效果上的差異即可。Furthermore, the roughness of the roughness pattern 120 can be adjusted, and the roughness pattern 120 is indicated by dots in FIG. However, in reality, the roughness of the rough pattern 120 may be formed in a state in which the touch of the naked eye and the hand is illegible, as long as the rough pattern 120 can cause a difference in optical effect with the first light guiding pattern 110 in a microscopic structure.
請再參照圖1，空白圖案130可由第一導光圖案110的周圍延伸而出。導光元件100通常是用光學透明材料所製作的，例如，壓克力、聚乙烯對苯二甲酸酯(polyethylene terephthalate,PET)等。第一導光圖案110例如可以使用熱壓印的方式來製作，藉由控制熱壓印製程，可使部分之熔融狀態的光學透明材料從第一導光圖案110的周圍往外溢流，而在第一導光圖案110的周圍形成空白圖案。藉由空白圖案130能夠造成更細緻的視覺效果，進一步強化第一導光圖案110與粗糙圖案120之間的視覺差異。如此，能夠使第一導光圖案110的發光輪廓更為清晰與銳利。Referring again to FIG. 1, the blank pattern 130 may be extended from the periphery of the first light guiding pattern 110. The light guiding element 100 is usually made of an optically transparent material such as acrylic, polyethylene terephthalate (PET) or the like. The first light guiding pattern 110 can be formed, for example, by hot stamping. By controlling the hot stamping process, a part of the molten transparent optical material can be overflowed from the periphery of the first light guiding pattern 110, and A blank pattern is formed around the first light guiding pattern 110. A more detailed visual effect can be caused by the blank pattern 130, and the visual difference between the first light guiding pattern 110 and the roughness pattern 120 is further enhanced. In this way, the illumination profile of the first light guiding pattern 110 can be made clearer and sharper.
圖2為本發明的另一實施例的導光元件的示意圖。請參照圖2，在導光元件100A中，第一導光圖案110可以有各種不同的形狀。同樣地，粗糙圖案120位於第一導光圖案110以外的區域。空白圖案130圍繞第一導光圖案110，且空白圖案130位於第一導光圖案110與粗糙圖案120之間。如圖2所示的導光元件100A也能夠良好地顯示局部的發光視覺效果。2 is a schematic view of a light guiding element according to another embodiment of the present invention. Referring to FIG. 2, in the light guiding element 100A, the first light guiding pattern 110 may have various shapes. Likewise, the roughness pattern 120 is located in a region other than the first light guiding pattern 110. The blank pattern 130 surrounds the first light guiding pattern 110, and the blank pattern 130 is located between the first light guiding pattern 110 and the roughness pattern 120. The light guiding element 100A shown in FIG. 2 can also display a partial illuminating visual effect well.
再者，導光元件100A可組裝到合適的裝置(如鍵盤等)中，各種形狀的第一導光圖案110可以對應到各種不同形狀的按鍵(未繪示)。更詳細而言，如圖2所示，圓形的第一導光圖案110可以設置在圓形按鍵(未繪示)的下方，且各個圓形按鍵之間的區域則對應到粗糙圖案120。因此，光源(未繪示)所提供的光線(未繪示)可輕易通過第一導光圖案110而照亮圓形按鍵，且光線通過粗糙圖案120的量相對較低，而使各個圓形按鍵之間的區域較暗。如此，可突顯出各圓形按鍵的發光視覺效果。Furthermore, the light guiding element 100A can be assembled into a suitable device (such as a keyboard or the like), and the first light guiding patterns 110 of various shapes can correspond to various shapes of keys (not shown). In more detail, as shown in FIG. 2, the circular first light guiding patterns 110 may be disposed under the circular keys (not shown), and the area between the respective circular keys corresponds to the rough pattern 120. Therefore, the light (not shown) provided by the light source (not shown) can easily illuminate the circular button through the first light guiding pattern 110, and the amount of light passing through the rough pattern 120 is relatively low, and the respective circles are made. The area between the buttons is dark. In this way, the luminous visual effect of each circular button can be highlighted.
值得注意的是，位於第一導光圖案110與粗糙圖案120之間的空白圖案130，更可進一步強化第一導光圖案110的發光視覺效果。類似地，如圖2所示，其他形狀(長方形、圓條形)的第一導光圖案110搭配粗糙圖案120與空白圖案130，能夠突顯出其他形狀的按鍵的發光視覺效果。It should be noted that the blank pattern 130 located between the first light guiding pattern 110 and the rough pattern 120 can further enhance the luminous visual effect of the first light guiding pattern 110. Similarly, as shown in FIG. 2, the first light guiding pattern 110 of other shapes (rectangular, round bar) is combined with the rough pattern 120 and the blank pattern 130 to highlight the luminous visual effect of the buttons of other shapes.
圖3為本發明的又一實施例的導光元件的示意圖。請參照圖3，此導光元件100B可應用在鍵盤中。如圖3所示，各個第一導光圖案110可對應鍵盤的每個鍵帽而設置，搭配粗糙圖案120與空白圖案130，可明顯區分發光區域的範圍。3 is a schematic view of a light guiding element according to still another embodiment of the present invention. Referring to FIG. 3, the light guiding element 100B can be applied to a keyboard. As shown in FIG. 3, each of the first light guiding patterns 110 may be disposed corresponding to each of the key caps of the keyboard, and the rough pattern 120 and the blank pattern 130 may be used to clearly distinguish the range of the light emitting regions.
圖4為本發明的再一實施例的導光元件的示意圖，其中，還繪示導光元件的右上角與右下角的局部區域的放大圖。請先參照圖4的導光元件100C的右下角的局部區域，導光元件100C可更包括：第二導光圖案140，相鄰於第一導光圖案110，其中，空白圖案130圍繞第一導光圖案110與第二導光圖案140、且設置於第一導光圖案110與第二導光圖案140之間。4 is a schematic view of a light guiding element according to still another embodiment of the present invention, wherein an enlarged view of a partial region of an upper right corner and a lower right corner of the light guiding element is also illustrated. Referring to the partial region of the lower right corner of the light guiding element 100C of FIG. 4, the light guiding element 100C may further include: a second light guiding pattern 140 adjacent to the first light guiding pattern 110, wherein the blank pattern 130 surrounds the first The light guiding pattern 110 and the second light guiding pattern 140 are disposed between the first light guiding pattern 110 and the second light guiding pattern 140.
更詳細而言，在圖3中，第一導光圖案110與第二導光圖案140彼此的距離相當接近，第一導光圖案110與第二導光圖案140之間可以沒有粗糙圖案120存在，而全部為空白圖案130。第一導光圖案110與第二導光圖案140之間的距離若是很小，則兩者之間不一定要設置粗糙圖案120。結果是，第一導光圖案110與第二導光圖案140整體相對於粗糙圖案120能夠突顯出發光視覺效果。In more detail, in FIG. 3, the distance between the first light guiding pattern 110 and the second light guiding pattern 140 is relatively close to each other, and the rough pattern 120 may not exist between the first light guiding pattern 110 and the second light guiding pattern 140. And all are blank patterns 130. If the distance between the first light guiding pattern 110 and the second light guiding pattern 140 is small, the roughness pattern 120 does not have to be provided between the two. As a result, the first light guiding pattern 110 and the second light guiding pattern 140 as a whole can highlight the luminous visual effect with respect to the rough pattern 120.
請再參照圖4的導光元件100C的右上角的局部區域，導光元件100C可更包括：第三導光圖案150，相鄰於導光元件100C的邊界R，且第三導光圖案150與導光元件100C的邊界R之間不具有粗糙圖案120。更詳細而言，在圖4中，由於第三導光圖案150離邊界R相當近，所以，無需再利用粗糙圖案120來進行發光區域的區隔。再者，當利用表面具有圖案的滾輪(未繪示)來壓印粗糙圖案120時，由於靠近第三導光圖案150的邊緣區域不會被滾輪所壓印到，所以不會在第三導光圖案150與導光元件100C的邊界R之間產生粗糙圖案120。Referring to the partial region of the upper right corner of the light guiding element 100C of FIG. 4 , the light guiding element 100C may further include: a third light guiding pattern 150 adjacent to the boundary R of the light guiding element 100C, and the third light guiding pattern 150 There is no roughness pattern 120 between the boundary R of the light guiding element 100C. In more detail, in FIG. 4, since the third light guiding pattern 150 is relatively close to the boundary R, it is not necessary to use the rough pattern 120 to separate the light emitting regions. Moreover, when the rough pattern 120 is imprinted by a roller (not shown) having a pattern on the surface, since the edge region near the third light guiding pattern 150 is not imprinted by the roller, it is not in the third guide. A roughness pattern 120 is created between the light pattern 150 and the boundary R of the light guiding element 100C.
圖5為本發明的一實施例的光源模組的示意圖。請參照圖5，光源模組200包括：導光元件210與光源220。導光元件210包括：至少一第一導光圖案212、粗糙圖案214以及空白圖案216。粗糙圖案214位於第一導光圖案212以外的區域。至少部分空白圖案216位於第一導光圖案212之外，且空白圖案216位於第一導光圖案212與粗糙圖案214之間。光源220設置在導光元件210的入光面210a的一側。FIG. 5 is a schematic diagram of a light source module according to an embodiment of the invention. Referring to FIG. 5 , the light source module 200 includes a light guiding component 210 and a light source 220 . The light guiding element 210 includes at least one first light guiding pattern 212, a rough pattern 214, and a blank pattern 216. The roughness pattern 214 is located in a region other than the first light guiding pattern 212. At least a portion of the blank pattern 216 is located outside the first light guiding pattern 212, and the blank pattern 216 is located between the first light guiding pattern 212 and the roughness pattern 214. The light source 220 is disposed on one side of the light incident surface 210a of the light guiding element 210.
如圖5所繪示的導光元件210採用上述的導光元件100，然而，實際上，導光元件210也可以採用上述的任一種導光元件100A～100C，詳細的內容在此不予以重述。另外，光源220可以採用發光二極體、有機發光二極體之類的點光源。總而言之，光源模組200可以提供良好的局部發光視覺效果。The light guiding element 210 shown in FIG. 5 adopts the above-mentioned light guiding element 100. However, in practice, the light guiding element 210 may also adopt any of the above-mentioned light guiding elements 100A to 100C, and the detailed content is not heavy here. Said. In addition, the light source 220 may be a point light source such as a light emitting diode or an organic light emitting diode. In summary, the light source module 200 can provide a good partial illumination visual effect.
綜上所述，本發明的導光元件與光源模組至少具有以下優點：In summary, the light guiding element and the light source module of the present invention have at least the following advantages:
在第一導光圖案之外的區域設置粗糙圖案，可提昇導光元件的整體摩擦力，可避免導光元件在組裝時產生滑動。利用粗糙圖案來區分出第一導光圖案，而能夠清晰地顯示第一導光圖案，產生良好的局部視覺外觀。藉由設置於第一導光圖案與粗糙圖案之間的空白圖案，進一步強化第一導光圖案與粗糙圖案之間的視覺差異，能夠使第一導光圖案的發光輪廓更為清晰與銳利。A rough pattern is provided in a region other than the first light guiding pattern, which can improve the overall frictional force of the light guiding element, and can prevent the light guiding element from slipping during assembly. The rough pattern is used to distinguish the first light guiding pattern, and the first light guiding pattern can be clearly displayed, resulting in a good partial visual appearance. The visual difference between the first light guiding pattern and the rough pattern is further enhanced by the blank pattern disposed between the first light guiding pattern and the rough pattern, so that the light guiding contour of the first light guiding pattern can be made clearer and sharper.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，故本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
