Description

導光條Light guide

本發明係與導光結構領域相關，尤其是一種導光條。The invention is related to the field of light guide structures, especially a light guide strip.

具備導光功效之光學產品，其應用範疇相當廣泛，各類需要照明、光源之裝置，皆可見其身影。該些產品因應所搭載使用的裝置、機構以及出光需求，可有各種不同的結構型式以及對應的光學設計，例如應用於顯示裝置中的導光結構則大多為同於面板之矩形片體設計。Optical products with light guiding function have a wide range of applications, and all kinds of devices that require lighting and light sources can be seen in them. These products can have a variety of different structural types and corresponding optical designs according to the devices, mechanisms, and light output requirements. For example, the light guide structures used in display devices are mostly the same as the rectangular panel design of the panel.

導光結構亦常被使用於傳真機、影印機等具有掃描影像讀取功能之裝置，此時導光結構則是作為提供該裝置掃描作動時之光線來源。應用於前述裝置的導光結構，其出光強度要求係超過一般照明之強度，始能供該些裝置利用強照明光線進而讀取或擷取影像。為利於光線透過導光結構向外射出，於導光結構上一般還須設計光學圖案，以控制出光表現。The light guide structure is also often used in devices with scanning image reading functions such as fax machines and photocopiers. At this time, the light guide structure is used as a light source for the scanning operation of the device. The light guide structure applied to the aforementioned devices requires that the light output intensity exceeds the intensity of general illumination, so that these devices can use strong illumination light to read or capture images. In order to facilitate light emission through the light guide structure, it is generally necessary to design an optical pattern on the light guide structure to control the light performance.

過往，光學圖案最早係採油墨印刷技術成形於導光結構上，例如透過絲網印刷方式將白色塗料轉印至導光結構表面，而形成光學圖案。惟印刷方式常發生轉印結構的尺寸受到溫度、濕度或溶劑狀況等因素，造成結構失真，使製造品質較不穩定。而後，係出現於導光結構上設計凹陷溝槽來控制出光狀態之技術手段，然其需透過複雜的設計與加工程序，才能在導光結構上形成精確之溝槽，進而造成加工成本過高，且僅具單種出光模式而使效果差強人意。更之後，係出現於導光結構上設置以C形狀方式去角，而形成用以作為放射平面之面結構，換言之，導光結構於去角後其截面會形成五邊形，且於切角部分形成出光，導光結構在縱方向之端部配置有發光源，光線進入導光結構後，係藉由其上之凹槽結構而自切角放射平面射出，據此希冀可解決出光效果不佳的問題。但該種技術手段仍不脫加工成本過高、加工不易等窘境。In the past, the optical pattern was first formed on the light guide structure using ink printing technology, for example, the white paint was transferred to the surface of the light guide structure by screen printing to form the optical pattern. However, the printing method often occurs that the size of the transfer structure is affected by factors such as temperature, humidity, or solvent conditions, resulting in structural distortions and unstable manufacturing quality. Then, there is a technical means of designing recessed grooves on the light guide structure to control the state of light. However, it needs to go through complicated design and processing procedures to form precise grooves on the light guide structure, resulting in high processing costs. , And only has a single light emitting mode, which makes the effect unsatisfactory. After that, the light guide structure is chamfered in a C shape to form a surface structure used as a radiation plane. In other words, the cross section of the light guide structure will form a pentagon after chamfering, and the corner will be cut. Part of the light is formed. The light guide structure is equipped with a light emitting source at the end of the longitudinal direction. After the light enters the light guide structure, it is emitted from the cut corner radiation plane through the groove structure on it. Therefore, it is hoped that the light emission effect can be solved. Good question. However, this kind of technical means still does not get rid of the dilemma of high processing cost and difficult processing.

綜上所述，本發明所揭露之導光條，於結構設計上更為簡易，亦利於加工生產，具備極佳之結構精確度，在簡易的結構下保有符合要求甚至更加優異之出光效果。本發明之導光條係於表面設計有特殊佈局狀態之導光結構，而可讓光線自出光面出光時，其光型可呈現略為向上的抬高光型以及相對較低的基底光型，讓導光條應用於掃描式裝置時可適用於各類待掃描物，提供所需之照明光線。In summary, the light guide strip disclosed in the present invention is simpler in structural design, and is also conducive to processing and production, has excellent structural accuracy, and has a simple structure that meets the requirements and even more excellent light-emitting effects. The light guide strip of the present invention is designed with a light guide structure with a special layout on the surface, and when light can be emitted from the light emitting surface, the light type can present a slightly upward elevated light type and a relatively low base light type, so that When the light guide is applied to scanning devices, it can be applied to all kinds of objects to be scanned and provide the required illumination light.

應用於影像掃描類型裝置之導光條，為了有效提供被掃描物照明光線，導光條之結構設計即為一相當重要的條件。先前技術中係提出變更導光體本身的結構形狀，以C型切角方式使得導光體之截面呈現五邊形，再以切角平面作為光放射平面出光，並在導光體上設計有多個凹槽，以據此進一步控制光線之出光狀態，使其出光可涵蓋主要掃描方向的整個長度。然而，導光產品之設計，除了須考量出光效果外，製造方面也是一個重要的設計要件，先前技術所提出之導光體結構，雖可達到較好的光線能量運用，但因整體結構生產複雜，進而須透過繁複工序始能完成製造，相當不便並衍生了高加工成本。For light guide strips used in image scanning devices, in order to effectively provide illuminating light for the scanned object, the structural design of the light guide strips is a very important condition. In the prior art, it is proposed to change the structural shape of the light guide itself, using a C-cut angle method to make the cross section of the light guide appear pentagonal, and then use the cut corner plane as the light emission plane to emit light, and the light guide is designed with A plurality of grooves are used to further control the light emission state, so that the light emission can cover the entire length of the main scanning direction. However, in the design of light guide products, in addition to considering the light output effect, manufacturing is also an important design element. Although the light guide structure proposed in the prior art can achieve better light energy utilization, it is complicated to produce due to the overall structure. Therefore, the manufacturing can be completed only through complicated procedures, which is quite inconvenient and derives high processing costs.

本案發明人遂因應該種應用之出光需求，針對導光條之光學圖案分布狀態予以構思及設計，並同步考量生產上之難易與產品良率等要件，綜合種種需求條件，進而提出具備簡易加工工序且可適用於各類掃描需求之導光條結構，詳細之技術特徵與可達成之功效係如下所述。其中，於實施方式中所提及之方向用語或名稱等，係為利於說明本發明之技術特徵，非用以限制本發明，並各圖式之內容亦僅為示意說明之用，非表示實際尺規大小或結構形狀等。In this case, the inventor of this case conceived and designed the optical pattern distribution state of the light guide strip in response to the light emission requirements of the application, and simultaneously considered the difficulty of production and the product yield, etc., combined various requirements and conditions, and then proposed that it has simple processing The process and the light guide structure that can be applied to various scanning needs, the detailed technical features and achievable effects are as follows. Among them, the directional terms or names mentioned in the embodiments are to help explain the technical features of the present invention, and are not used to limit the present invention, and the contents of the drawings are also for illustrative purposes only, and do not represent actual Ruler size or structure shape, etc.

The intersection of the first short side 121 and the bottom long side 124 is the origin of the vertical coordinate system, the bottom long side 124 is the X axis, the first short side 121 is the Y axis, the starting point I is located on the top long side 123 and the coordinates are (X _i ,Y _i ), the coordinates of the first turning point A are (X ₁ ,Y ₁ ), the coordinates of the second turning point B are (X ₂ ,Y ₂ ), and the coordinates of the third turning point C (X ₃ ,Y ₃ ), The end point T is located on the second short side 122 and the coordinates are (X _t , Y _t ), where Y _i ≧Y _t ＞Y ₃ ＞Y ₂ =Y ₁ , X _t ＞X ₃ ＞X ₂ ＞X ₁ ＞X _i , and further constitute the state of the rib arrangement area 125 as shown in FIG. 2, the light guide ribs 13 are respectively arranged in the rib arrangement area 125. In other words, taking the height as the description of the positional relationship of each point on the Y axis, the height of the starting point I and the end point T can be the same, or the height of the starting point I can be greater than the end point T, and the height of the third turning point C can be less than The starting point I and the ending point T are both greater than the second turning point B and the first turning point A, and the heights of the first turning point A and the second turning point B remain horizontal. Wherein, each light guide rib 13 is a bump structure protruding from the surface of the optical adjustment surface 12, and the volume of each light guide rib 13 is quite small relative to the light guide strip 1, which is convenient for showing these The arrangement state of the light guide ribs 13 on the optical adjustment surface 12 is indicated by a straight line in Figures 1 and 2 to show the distribution of the light guide ribs 13 and the further structure and shape of the light guide ribs 13 Signal, please elaborate later. Accordingly, through the aforementioned shape of the rib arrangement area 125, after the light enters the light guide strip 1 from the light incident side 11, it is acted by the light guide rib 13, which can provide uniform and sufficient brightness of the illumination light, and at the same time.

更具體地說，本實施方式於應用時，係設置一如LED之光源2於入光側面11處，以利入光側面11接收側入光線，光線進入導光條1內後，即受到分布於凸稜設置區12內的導光凸稜13作用而於出光面10出光，再照射到被掃描物，續以反射至掃描裝置之接收器以利形成影像，於此請一併參閱第3圖，其係為本發明一實施方式之導光條應用示意圖，導光條1於實際應用在影像掃描裝置內時，係會呈現反向放置之狀態，亦即如第3圖所示，光學調整面12之底長邊124會在上方，頂長邊121則在下方，導光凸稜13之分布狀態亦請參閱圖中所示，同樣地，為利於示意該些導光凸稜13於光學調整面12上的佈設狀態，於此亦以直線表示之，而圖中所示之光線走向僅為一較佳示意，實際上導光條1於作用時係之出光係會涵蓋整個出光面10，且應會具有兩種光型，容後述明。此外，實際應用上，於導光條1外側亦可設置無遮蔽於出光面1之罩體以利作為安裝固定用之組件。More specifically, when this embodiment is applied, a light source 2 like an LED is installed at the light incident side 11 to facilitate the light incident on the light incident side 11 to receive light from the side. After the light enters the light guide 1, it is distributed The light guide ribs 13 in the rib setting area 12 act to emit light on the light emitting surface 10, and then irradiate the scanned object, and then reflect to the receiver of the scanning device to facilitate the formation of an image. Please also refer to section 3 here. Figure, which is a schematic diagram of the application of a light guide strip according to an embodiment of the present invention. When the light guide strip 1 is actually used in an image scanning device, it will be placed in a reversed state, that is, as shown in Figure 3, the optical The bottom long side 124 of the adjusting surface 12 will be on the upper side, and the top long side 121 will be on the bottom. Please refer to the figure for the distribution of the light guide ribs 13 as well. Similarly, to show that the light guide ribs 13 are at The arrangement state on the optical adjustment surface 12 is also represented by a straight line here, and the light direction shown in the figure is only a better indication. In fact, the light emitting system of the light guide strip 1 will cover the entire light emitting surface when it is acting. 10. It should have two light types, which will be explained later. In addition, in practical applications, a cover body that is not shielded on the light exit surface 1 can also be provided on the outside of the light guide strip 1 to facilitate installation and fixation of components.

透過本發明之導光條1結構，光線於出光面10大致形成方向略有不同的兩種出光光型，其一是基底光型，其二是抬高光型。其中導光條1接收由入光側面11入射之光線後，所形成較為靠下之基底光型光線，較大比例來自靠近光學調整面12之底長邊124的該些導光凸稜13結構作用形成，如此可針對厚度較薄的被掃描物提供足夠照明強度之光現。而抬高光型光線則較大比例來自凸稜設置區125內鄰近邊界線126位置的導光凸稜13作用形成，並呈現較偏上的出光狀態，故當導光條1係需針對厚度較厚的被掃描物提供照明光線時，透過偏上之抬高光型結合偏下的基底光型，給予具備足夠強度之照明光線，避免掃描後的影像失真或不清晰。此外，據第2圖所示，基於前述邊界線126上各點相對位置關係式，可見邊界線126之高度於起點I是與第一短邊121長度等高的，待往第二短邊122方向延伸一段距離後高度則呈減縮並再次拉升之狀態，最後則是朝向第二短邊122而與第二短邊122接合，如此邊界線126與第一短邊121、第二短邊122及底長邊124夾設形成之凸稜設置區125，會呈現初始涵蓋範圍大，而後減縮並再次提升的狀態。透過該種凸稜設置區125，可兼具讓出光光型符合所需以及讓出光面之出光強度均勻地涵蓋出光面10整體之功效。Through the structure of the light guide strip 1 of the present invention, there are two light emitting types with slightly different directions of the light rays on the light emitting surface 10, one of which is the base light type, and the other is the elevated light type. After the light guide strip 1 receives the light incident from the light incident side 11, the lower base light type light is formed, and a larger proportion comes from the light guide ribs 13 structures close to the bottom long side 124 of the optical adjustment surface 12 The effect is formed, so that it can provide sufficient illumination intensity for the thinner object to be scanned. The elevated light type light is formed by the action of the light guide rib 13 adjacent to the boundary line 126 in the rib arrangement area 125, and presents a relatively upward light output state. Therefore, when the light guide strip 1 is relatively thick When the thick object to be scanned provides illumination light, through the upper elevation light type combined with the lower base light type, the illumination light with sufficient intensity is given to avoid the image distortion or unclearness after scanning. In addition, as shown in Figure 2, based on the aforementioned relative positional relationship of the points on the boundary line 126, it can be seen that the height of the boundary line 126 at the starting point I is the same as the length of the first short side 121, and the second short side 122 After the direction is extended for a certain distance, the height is reduced and pulled up again, and finally it faces the second short side 122 and joins the second short side 122, so that the boundary line 126 is connected to the first short side 121 and the second short side 122 The rib setting area 125 formed between the bottom long side 124 and the bottom long side 124 will have a large initial coverage area, and then shrink and rise again. Through this kind of rib arrangement area 125, the light emission pattern can meet the requirements and the light intensity of the light emission surface can uniformly cover the entire light emission surface 10.

為使出光效果更為優越，關於凸稜設置區125邊界線126上各點相對光學調整面12於X、Y軸長度之占比，亦即各點之座標位置，本發明亦提出進一步地限制。當第一短邊121之長度為H，底長邊124之長度為L時，X ₁為0.03L～0.034L，Y ₁為0.19H～0.21H；X ₂為0.07L～0.076L；X ₃為0.09L～0.098L，Y ₃為0.49H～0.66H。透過上述條件決定邊界線125之起點I、第一轉折點A、第二轉折點B、第三轉折點C及終點T位置後所形成之凸稜設置區125，其內的導光凸稜13係能發揮更好的導光效果，以使導光條1更為確實地形成所需出光狀態。 In order to achieve a better light-emitting effect, the present invention also proposes further restrictions regarding the ratio of the points on the boundary line 126 of the rib arrangement area 125 relative to the length of the optical adjustment surface 12 in the X and Y axes, that is, the coordinate positions of the points. . When the length of the first short side 121 is H and the length of the bottom long side 124 is L, X ₁ is 0.03L～0.034L, Y ₁ is 0.19H～0.21H; X ₂ is 0.07L～0.076L; X ₃ It is 0.09L to 0.098L, and Y ₃ is 0.49H to 0.66H. After determining the starting point I, the first turning point A, the second turning point B, the third turning point C, and the end point T of the boundary line 125 through the above conditions, the rib setting area 125 is formed, and the light guiding rib 13 inside can be used Better light guiding effect, so that the light guiding strip 1 can form the required light emitting state more reliably.

本發明之導光條1具體來說可透過射出成型製成，並由於須在光學調整面12形成凸出狀的導光凸稜13，因此於射出成型模具上係可先透過刀具加工形成溝槽結構，射出成型的成品即形成對應的凸稜。特別一提的是，射出成型相較於直接針對產品進行切削加工而言，係可消除切削後之殘屑留置現象對產品品質的影響，因此射出成型實為較好的製造方式選項，又於模具上形成溝槽係相對簡易，因此本發明之導光條1除了於製程上相對容易外，產出品質亦相對優異而具備極高產品良率，同時亦使導光條1在具有較單純之結構下，發揮更優異的出光效果。Specifically, the light guide strip 1 of the present invention can be made by injection molding, and because it is necessary to form a convex light guide rib 13 on the optical adjustment surface 12, the injection molding mold can be processed by a tool to form a groove first. With groove structure, the finished product formed by injection molding will form corresponding ribs. In particular, injection molding can eliminate the impact of residual chip retention after cutting on product quality compared to directly cutting the product. Therefore, injection molding is actually a better manufacturing option, and it is also a better manufacturing option. It is relatively easy to form grooves on the mold. Therefore, the light guide strip 1 of the present invention is relatively easy in the manufacturing process, and the output quality is relatively excellent and has a very high product yield. At the same time, the light guide strip 1 has a relatively simple Under the structure, it exerts a more excellent light-emitting effect.

The distance P between any two adjacent light guide ribs 13 is 120-150 μm. In an implementation state, the light guide rib 13 is a convex structure with a circular arc at the top, and through the aforementioned ruler, the light guide rib 13 can exert a better light guiding effect, allowing the light guide strip 1 to emerge from the light surface 10 The light intensity, uniformity and light pattern of the output light can meet the requirements.

請續以參閱第1及5圖，其中第5圖係為本發明一實施方式另一實施狀態之光學調整面示意圖。除了前述之結構示例外，導光條1之另一結構狀態可為使邊界線126更具有一分隔點D，且由分隔點D平行X軸延伸至第二短邊122而形成一分隔線127，分隔點D之座標為(X _4,Y ₄)，且X ₂＜X ₄≦X ₃，Y ₃≧Y ₄＞Y ₂，並於凸稜設置區125中分隔線127以上的區域佈設有複數控光網點14。光學調整面12佈設有控光網點14時，導光條1的整體結構仍如同第1圖所示般為一矩形結構，但在光學調整面12之凸稜設置區125中具有不同的光學結構設置。具體來說係如第5圖所示，以分隔線127為區隔，分隔線127以上的區域佈設有控光網點14，凸稜設置區125其他區域則設置有導光凸稜13，而形成同時應用控光網點14及導光凸稜13之結構狀態。該些控光網點14之佈設密度，係可依據與入光側面11的遠近予以調整，以使導光條1之出光均勻度與光型分布符合所需，原則上會呈現距離入光側面11越近分布密度越小之設置狀態。其中，於本實施狀態中係以分隔點D和第三轉折點C重合為例，且於第5圖中，控光網點14之造型僅為示意，並非表示實際形狀，且為利於示意該些導光凸稜13於光學調整面12上的佈設狀態，於圖中亦先以直線示意之。 Please continue to refer to FIGS. 1 and 5. FIG. 5 is a schematic diagram of an optical adjustment surface in another implementation state of an embodiment of the present invention. In addition to the foregoing structural examples, another structural state of the light guide strip 1 can be such that the boundary line 126 has a separation point D, and the separation point D extends parallel to the X axis to the second short side 122 to form a separation line 127 , The coordinates of the dividing point D are (X _4, Y ₄ ), and X ₂ ＜X ₄ ≦X ₃ , Y ₃ ≧Y ₄ ＞Y ₂ , and are arranged in the rib setting area 125 above the dividing line 127 Complex CNC optical network point 14. When the optical adjustment surface 12 is provided with light control dots 14, the overall structure of the light guide strip 1 is still a rectangular structure as shown in Fig. 1, but there are different optical structures in the rib arrangement area 125 of the optical adjustment surface 12 Set up. Specifically, as shown in Figure 5, the partition line 127 is used as the partition, the area above the partition line 127 is provided with light control dots 14, and the other areas of the rib setting area 125 are provided with light guide ribs 13, forming At the same time, the structural state of the light control dots 14 and the light guide ribs 13 are applied. The arrangement density of the light control dots 14 can be adjusted according to the distance to the light incident side 11, so that the light uniformity and light type distribution of the light guide strip 1 meet the requirements. In principle, the distance from the light incident side 11 is shown. The closer the distribution density is, the smaller the setting state. Among them, in the present embodiment, the overlap of the separation point D and the third turning point C is taken as an example, and in Figure 5, the shape of the light control dots 14 is only for illustration, not the actual shape, and to facilitate the illustration of these guides. The arrangement state of the light convex ridge 13 on the optical adjustment surface 12 is also indicated by a straight line first in the figure.

如前述，本發明之導光條1係可採射出成型方式製成，而位於凸稜設置區125內分隔線127以上區域中的控光網點14，其亦可透過射出成型方式形成，該些控光網點14係屬於凸出於光學調整面12之結構，而用以製成導光條1之模具上，亦可藉由各類加工方式先形成溝槽狀的網點，以使成品射出後形成對應為凸出狀之控光網點14。透過控光網點14與導光凸稜13之配合，光線由入光側面11進入導光條1後，即可因應導光凸稜13與控光網點14結構，於出光面10形成均勻並具有足夠強度之出光，同時亦能利用光型提升掃描時的照明效能。As mentioned above, the light guide strip 1 of the present invention can be made by injection molding, and the light control dots 14 located in the area above the dividing line 127 in the rib setting area 125 can also be formed by injection molding.

Through the cooperation of the light control dots 14 and the light guide ribs 13, after the light enters the light guide strip 1 from the light incident side 11, the light guide ribs 13 and the light control dots 14 can be formed uniformly and have a shape on the light exit surface 10. The light with sufficient intensity can also use the light pattern to improve the lighting efficiency during scanning.

進一步地，分隔線127相對光學調整面12之相對位置，係可設定為當第一短邊121之長度為H，底長邊124之長度為L時，Y ₄為0.49H～0.51H，X ₄為0.041～0.049L。據此，針對控光網點14之佈設區域大小，係能具有更好的限制，以確保光線透過控光網點14作用出光後，能形成符合所需的出光狀態。 Further, the relative position of the dividing line 127 with respect to the optical adjustment surface 12 can be set as when the length of the first short side 121 is H and the length of the bottom long side 124 is L, Y ₄ is 0.49H～0.51H, X ₄ is 0.041～0.049L.

Among them, the density of light control dots 14 per unit area accounts for 10 to 78%, which means that after the light control dots 14 are arranged above the dividing line 127, the density of light control dots 14 in the framed area will be selected. It is 10 to 78%.

於本實施方式中，第一邊界線129與第二邊界線120係呈鏡像設置，可參閱第8圖所示，換言之，即是凸稜設置區125於左右兩邊呈對稱設置之狀態，如此由第一短邊121及第三短邊128所鄰接之入光側面11進入之光線，皆能因應導光凸稜13作用而由出光面10以所需狀態出光。同樣地，導光凸稜13係佈設於凸稜設置區125中，並為利於說明，於第7、8圖中亦以實線表示之，導光凸稜13之具體結構可參閱第4A、4B圖所示，於一實施狀態下，其係分別呈弧形，且導光凸稜13之頂部圓弧直徑R ₁為57±4μm，底部寬度W為60±4μm，高度h ₁為16±3μm，任二相鄰之導光凸稜13之間距P為120～150μm。於前述尺規下，導光凸稜13係能讓進入導光條1之光線形成更好的調整效果，以符合出光需求。 In this embodiment, the first boundary line 129 and the second boundary line 120 are arranged in a mirror image, as shown in Fig. 8. In other words, the rib arrangement area 125 is arranged symmetrically on the left and right sides. The light entering the light incident side surface 11 adjacent to the first short side 121 and the third short side 128 can all emit light from the light emitting surface 10 in a desired state in response to the action of the light guiding rib 13. Similarly, the light guide rib 13 is arranged in the rib setting area 125, and for the convenience of description, it is also represented by solid lines in Figures 7 and 8. For the specific structure of the light guide rib 13 please refer to Section 4A, As shown in Figure 4B, in an implementation state, they are respectively arc-shaped, and the top arc diameter R ₁ of the light guide rib 13 is 57 ± 4 μm, the bottom width W is 60 ± 4 μm, and the height h ₁ is 16 ± 3μm, the distance P between any two adjacent light guide ribs 13 is 120-150μm. Under the aforementioned ruler, the light guide ribs 13 can make the light entering the light guide strip 1 have a better adjustment effect to meet the light emission requirements.

另外，當導光條1為雙側入光時，對於第一邊界線129上各點位置，亦能具備進一步之限制條件，當第一短邊121之長度為H，底長邊124之長度為L時，X ₁為0.015L～0.017L，Y ₁為0.19H～0.21H；X ₂為0.035L～0.038L；X ₃為0.045L～0.049L，Y ₃為0.49H～0.66H。同樣地，如此能使凸稜設置區12呈現更好的分佈狀態，促進出光調整效果。當第一邊界線129上各點之座標位置在前述範圍內時，由於第二邊界線120為第一邊界線129之鏡射，因此第二邊界線120上對應位置的座標點位置，亦會符合前述條件。 In addition, when the light guide strip 1 receives light from both sides, further restriction conditions can be met for each point on the first boundary line 129. When the length of the first short side 121 is H, the length of the bottom long side 124 When it is L, X ₁ is 0.015L to 0.017L, Y ₁ is 0.19H to 0.21H; X ₂ is 0.035L to 0.038L; X ₃ is 0.045L to 0.049L, and Y ₃ is 0.49H to 0.66H. Similarly, in this way, the rib arrangement area 12 can present a better distribution state, and the light emission adjustment effect can be promoted. When the coordinate position of each point on the first boundary line 129 is within the aforementioned range, since the second boundary line 120 is a mirror of the first boundary line 129, the coordinate point position of the corresponding position on the second boundary line 120 will also be Meet the aforementioned conditions.

請延續參閱前述圖示並再一併參閱第9圖，第9圖係為本發明另一實施方式之導光條應用示意圖。應用時，導光條1實際上會呈光學調整面12之底長邊124朝上之狀態，如第9圖所示，而圖中所示之光線走向僅為一較佳示意，實際上導光條1於作用時係之出光係會涵蓋整個出光面10。於導光條1之入光側面11處係分別對應設置光源2，當光源2的光線由入光側面11進入導光條1內以後，受到特殊分佈狀態的導光凸稜13作用，光線即可藉由出光面10形成均勻且具備足夠強度的出光，以照射至被掃描物並反射而為掃描裝置之接收器所接受。同樣地，光線於出光面10出光時亦會大致呈現略為向上照射的抬高光型與相對抬高光型略低位置的基底光型，如此於應用時針對不同的被掃描物，導光條1都能提供足夠強度且符合掃描路徑之照明光線，有效提升掃描影像之清晰度。關於抬高光型與基底光型之具體描述與效用，前述段落文字已有敘及，再請復觀看對應內容。Please continue to refer to the foregoing illustrations and also refer to FIG. 9 together. FIG. 9 is a schematic diagram of the light guide strip application according to another embodiment of the present invention. In application, the light guide strip 1 will actually be in a state where the bottom long side 124 of the optical adjustment surface 12 faces upwards, as shown in Fig. 9, and the light direction shown in the figure is only a better indication. The light emitting system of the light bar 1 when it is in action will cover the entire light emitting surface 10. The light source 2 is respectively provided at the light entrance side 11 of the light guide strip 1. When the light from the light source 2 enters the light guide strip 1 from the light entrance side 11, it is affected by the light guide ribs 13 in a special distribution state, and the light is The light-emitting surface 10 can be used to form a uniform and sufficient intensity of light to illuminate the scanned object and be reflected by the receiver of the scanning device. Similarly, when the light exits from the light-emitting surface 10, it will generally show a slightly upward-illuminated elevated light type and a slightly lower base light type relative to the elevated light type. In this way, for different scanned objects during application, the light guide strip 1 It can provide sufficient intensity and in line with the scanning path of the illumination light, effectively improving the clarity of the scanned image. Regarding the specific description and utility of the elevated light type and the base light type, the text in the preceding paragraph has already been mentioned, please review the corresponding content again.

接續，請一併參閱第10圖，其係為本發明另一實施方式另一實施狀態之光學調整面示意圖。凸稜設置區125內除了遍佈設有導光凸稜13外，另一個實施狀態為，第一邊界線129更具有一分隔點D，且由分隔點D平行X軸延伸至第二短邊122而形成一分隔線127，分隔線127以第二短邊122鏡像延伸至第三短邊128，其中分隔點D之座標為(X ₄,Y ₄)，且X ₂＜X ₄≦X ₃，Y ₃≧Y ₄＞Y ₂，凸稜設置區125中分隔線127以上之區域佈設有複數控光網點14。在此結構狀態下，導光條1整體形狀仍是矩形而如第7圖所示，其差異在於凸稜設置區125內更具有分隔線127，並在分隔線127以上設置控光網點14。該些控光網點14為凸出狀，並該些控光網點14係能使部分射出之光線形成略朝上之抬高光型，於此結構狀態導光條1亦具備易於生產及優異出光表現之優點。 For the continuation, please also refer to FIG. 10, which is a schematic diagram of an optical adjustment surface in another implementation state of another embodiment of the present invention. In addition to the light guide ribs 13 all over the rib arrangement area 125, another implementation state is that the first boundary line 129 further has a separation point D, and the separation point D extends parallel to the X axis to the second short side 122 A dividing line 127 is formed. The dividing line 127 mirrors the second short side 122 and extends to the third short side 128. The coordinates of the dividing point D are (X ₄ , Y ₄ ), and X ₂ <X ₄ ≦X ₃ , Y ₃ ≧Y ₄ ＞Y ₂ , the area above the dividing line 127 in the rib setting area 125 is provided with complex numerical control light dots 14. In this structure state, the overall shape of the light guide strip 1 is still rectangular as shown in FIG. 7. The difference is that the rib arrangement area 125 further has a dividing line 127, and the light control dots 14 are arranged above the dividing line 127. The light control dots 14 are convex, and the light control dots 14 can make part of the emitted light form a slightly upward raised light type. In this structure state, the light guide 1 also has easy production and excellent light output performance. The advantages.

進一步地，分隔點D ₁之座標位置亦能有對應之限制條件，於一實施狀態下，當第一短邊121長度為H，底長邊124長度為L時，Y ₄為0.49H～0.51H，X ₄為0.041～0.049L。據此可使控光網點14之分佈更為適切，以發揮更好的控光作用。 Further, the coordinate position of the dividing point D ₁ can also have corresponding restrictions. In an implementation state, when the length of the first short side 121 is H and the length of the bottom long side 124 is L, Y ₄ is 0.49H～0.51 H, X ₄ is 0.041～0.049L. Accordingly, the distribution of the light control dots 14 can be more appropriate to play a better light control effect.

另一方面，為了確保出光效果符合所需，本發明亦提出控光網點14結構尺規限制，請復搭配參閱第6A、6B圖，於一實施狀態下，控光網點14之直徑R ₂為100±5μm，高度h ₂為20±5μm，且控光網點14之單位面積密度占比為10～78%。誠如前述，控光網點14係可依據與入光側面11之距離而調配分布密度，以讓出光更為均勻化，在雙側入光之應用下亦是如此，是以，控光網點14於分隔線127以上的區域，其單位面積密度占比亦會介於一個範圍內，而於此係揭露密度占比為10～78%。 On the other hand, in order to ensure that the light-emitting effect meets the requirements, the present invention also proposes restrictions on the structure of the light-controlling dots 14. Please refer to Figures 6A and 6B for the combination. In an implementation state, the diameter R ₂ of the light-controlling dots 14 is 100±5μm, the height h ₂ is 20±5μm, and the unit area density of the light control dots 14 is 10-78%. As mentioned above, the light control dots 14 can be adjusted according to the distance from the light incident side 11 to adjust the distribution density to make the light more uniform. This is also true in the application of double-side light incidents. Therefore, the light control dots 14 In the area above the dividing line 127, the proportion of the density per unit area will also be within a range, and the proportion of the exposed density here is 10 to 78%.
