〔第一實施例〕[First Embodiment]
請參閱圖1所示，本發明第一實施例提供一種導光結構S，其包括一導光板1及一發光單元2。舉例來說，導光結構S可應用於顯示面板的背光源，或是任何需要光源的電子設備，然而本發明不以此為限。Referring to FIG. 1 , a first embodiment of the present invention provides a light guiding structure S including a light guide plate 1 and a light emitting unit 2 . For example, the light guiding structure S can be applied to a backlight of a display panel or any electronic device that requires a light source, but the invention is not limited thereto.
首先，第一實施例所提供的導光板1為一具有兩相對應長側邊11及兩相對應短側邊12的矩形透明導光板，其上、下表面可以依據不同的需要來設計導光微結構，並且任意一長側邊11與任意一短側邊12彼此相鄰接。以下內容將以圖1中所標示的其中一長側邊11及其中一短側邊12來進行說明，然而本發明實施例不以此為限。First, the light guide plate 1 provided in the first embodiment is a rectangular transparent light guide plate having two corresponding long side edges 11 and two corresponding short side edges 12, and the upper and lower surfaces can be designed according to different needs. Microstructure, and any one of the long sides 11 and any one of the short sides 12 are adjacent to each other. The following description will be made with one of the long sides 11 and one of the short sides 12 as indicated in FIG. 1, but the embodiment of the present invention is not limited thereto.
再者，發光單元2包括一設置在導光板1的長側邊11的一旁的第一發光模組21及一設置在導光板1的短側邊12的一旁的第二發光模組22。其中，第一發光模組21包括一第一電路基板210及多個設置於第一電路基板210上且面向導光板1的長側邊11的第一發光元件211，並且多個第一發光元件211所產生的光束會直接投向導光板1的長側邊11。另外，第二發光模組22包括一第二電路基板220及多個設置於第二電路基板220上且面向導光板1的短側邊12的第二發光元件221，並且多個第二發光元件221所產生的光束會直接投向導光板1的短側邊12。Furthermore, the light-emitting unit 2 includes a first light-emitting module 21 disposed on one side of the long side 11 of the light guide plate 1 and a second light-emitting module 22 disposed on a side of the short side 12 of the light guide plate 1. The first light emitting module 21 includes a first circuit substrate 210 and a plurality of first light emitting elements 211 disposed on the first circuit substrate 210 and facing the long sides 11 of the light guide plate 1 , and the plurality of first light emitting elements The light beam generated by 211 is directly cast onto the long side 11 of the light guide plate 1. In addition, the second light emitting module 22 includes a second circuit substrate 220 and a plurality of second light emitting elements 221 disposed on the second circuit substrate 220 and facing the short sides 12 of the light guide plate 1 , and the plurality of second light emitting elements The light beam generated by 221 is directly directed to the short side 12 of the light guide plate 1.
舉例來說，第一電路基板210及第二電路基板220皆可為金屬基印刷電路板(Metal Core PCB，MCPCB)，其中MCPCB是將原有的印刷電路板附貼在另外一種熱傳導效果更好的鋁、銅或鐵金屬基板上，以增進印刷電路板的散熱效能，然而本發明實施例不以此為限。另外，第一發光元件211及第二發光元件221皆可為發光二極體(LED)，其中多個LED可通過COB(Chip on board)的方式以設置在相對應的MCPCB上，然而本發明實施例不以此為限。For example, the first circuit substrate 210 and the second circuit substrate 220 may each be a metal-based printed circuit board (MCPCB), wherein the MCPCB attaches the original printed circuit board to another heat conduction effect. The aluminum, copper or iron metal substrate is used to improve the heat dissipation performance of the printed circuit board. However, the embodiment of the present invention is not limited thereto. In addition, the first illuminating element 211 and the second illuminating element 221 can be light emitting diodes (LEDs), wherein the plurality of LEDs can be disposed on the corresponding MCPCB by way of COB (Chip on Board), but the present invention The embodiment is not limited thereto.
更進一步來說，第二電路基板220的基板長度L2會大於第一 電路基板210的基板長度L1，並且多個第二發光元件221所使用的顆數(N2)會大於多個第一發光元件211所使用的顆數(N1)。經實際測試與實驗得知，在導光板1能夠達到一特定標準導光均勻度的條件設定下，“雙邊設置光源模式(亦即第一發光模組21及第二發光模組22分別設置在導光板1的長側邊11及短側邊12的一旁)”所使用的第一電路基板210及第二電路基板220加起來後的總長度(L1+L2)僅需要“單邊設置光源模式(亦即只有設置一發光模組在導光板1的短側邊Y的一旁)”所使用的電路基板的總長度的25%即可。另外，經實際測試與實驗得知，在導光板1能夠達到一特定標準均勻度的條件設定下，“雙邊設置光源模式”所使用的多個第一發光元件211及多個第二發光元件221加起來後的總顆數(N1+N2)也是僅需要“單邊設置光源模式”所使用的發光元件的總顆數的25%即可。藉此，依據上述第一實施例的“雙邊設置光源模式”來實現本發明的導光結構S時，在導光板1能夠達到一特定標準導光均勻度的條件設定下，本發明不僅可以有效減少LED所使用的總顆數(至少可比“單邊設置光源模式”減少75%)，並且也可有效減少MCPCB所使用的總長度(至少可比“單邊設置光源模式”減少75%)，藉此以達到降低成本及環保節能的目的。Furthermore, the substrate length L2 of the second circuit substrate 220 is greater than the first The substrate length L1 of the circuit substrate 210 and the number of used (N2) of the plurality of second light-emitting elements 221 are larger than the number (N1) used by the plurality of first light-emitting elements 211. According to actual tests and experiments, under the condition that the light guide plate 1 can reach a specific standard light guide uniformity, the "bilaterally set light source mode (that is, the first light emitting module 21 and the second light emitting module 22 are respectively disposed at The total length (L1+L2) of the first circuit substrate 210 and the second circuit substrate 220 used for the first side of the long side 11 and the short side 12 of the light guide plate 1 is only required to be unilaterally set. (that is, only one illumination module is disposed on the side of the short side Y of the light guide plate 1)" may be 25% of the total length of the circuit substrate used. In addition, after actual testing and experimentation, the plurality of first light-emitting elements 211 and the plurality of second light-emitting elements 221 used in the “bilaterally disposed light source mode” are set under the condition that the light guide plate 1 can reach a certain standard uniformity. The total number of added (N1+N2) is also 25% of the total number of light-emitting elements used in the "single-side light source mode". Therefore, when the light guiding structure S of the present invention is implemented according to the "bilaterally disposed light source mode" of the first embodiment described above, the present invention can be effectively effective only under the condition that the light guiding plate 1 can achieve a specific standard light guiding uniformity. Reduce the total number of LEDs used (at least 75% less than the “unilaterally set light source mode”), and also reduce the total length used by the MCPCB (at least 75% less than the “unilaterally set light source mode”). This is to achieve the purpose of reducing costs and environmental protection and energy conservation.
舉例來說，經實際測試與實驗得知，多個第二發光元件221與多個第一發光元件211的最佳顆數比例可為8：2(如圖1所示)，次之的較佳比例可為7：3或9：1。另外，經實際測試與實驗得知，多個第一發光元件211及多個第二發光元件221所使用的顆數，可以分別符合下列公式：N1=(1.42×10-3 )X~(5.7×10-3 )X及N2=0.028Y~0.01Y，其中N1為多個第一發光元件211所使用的顆數，N2為多個第二發光元件221所使用的顆數，X為導光板1的長側邊11的長側邊長度，Y為導光板1的短側邊12的短側邊長度，長度的單位皆為毫米(mm)。然而，本發明不以上述所舉的例 子為限。For example, after actual testing and experimentation, the optimal ratio of the plurality of second illuminating elements 221 to the plurality of first illuminating elements 211 can be 8:2 (as shown in FIG. 1), and the second is compared. The preferred ratio can be 7:3 or 9:1. In addition, the actual number of the first light-emitting elements 211 and the plurality of second light-emitting elements 221 can be respectively determined by the following formulas: N1=(1.42×10 -3 )X~(5.7 ×10 -3 )X and N2=0.028Y~0.01Y, where N1 is the number of the plurality of first light-emitting elements 211, N2 is the number of the plurality of second light-emitting elements 221, and X is the light guide plate. The length of the long side of the long side 11 of 1 and Y are the lengths of the short sides of the short side 12 of the light guide plate 1, and the units of the length are all in millimeters (mm). However, the invention is not limited to the examples set forth above.
值得一提的是，如圖1所示，導光板1的長側邊11及短側邊12以大致上彼此垂直的方式連接於一轉折點10，並且第一發光模組21及第二發光模組22皆非常靠近轉折點10。經實際測試與實驗得知，當第二發光模組22相距轉折點10的最短水平偏移距離D2大於第一發光模組21相距轉折點10的最短水平偏移距離D1時，本發明將可有效解決角落暗帶及減少暗亮差的問題，以更加提升導光板1的導光均勻度。It is to be noted that, as shown in FIG. 1 , the long side 11 and the short side 12 of the light guide plate 1 are connected to a turning point 10 in a manner substantially perpendicular to each other, and the first light emitting module 21 and the second light emitting module are Group 22 is very close to turning point 10. According to actual tests and experiments, when the shortest horizontal offset distance D2 of the second lighting module 22 from the turning point 10 is greater than the shortest horizontal offset distance D1 of the first lighting module 21 from the turning point 10, the present invention can effectively solve the problem. The dark band of the corner and the problem of reducing the darkness and the difference are used to further improve the light guiding uniformity of the light guide plate 1.
〔第二實施例〕[Second embodiment]
請參閱圖2所示，本發明第二實施例提供一種導光結構S。由圖2與圖1的比較可知，本發明第二實施例與第一實施例最大的差別在於：在第二實施例中，導光板1具有一連接於長側邊11及短側邊12之間的斜側邊13，並且發光單元2包括一設置在導光板1的斜側邊13的一旁的第三發光模組23，其中第三發光模組23包括一第三電路基板230及多個設置於第三電路基板230上且面向導光板1的斜側邊13的第三發光元件231。舉例來說，多個第三發光元件231所使用的顆數可符合下列公式：N3=(1.43×10-3 )X~(4.8×10-3 )X，其中N3為多個第三發光元件231所使用的顆數，X為導光板1的長側邊11的長側邊長度(第二實施例的長側邊長度X會小於第一實施例的長側邊長度X)，長度的單位為毫米。Referring to FIG. 2, a second embodiment of the present invention provides a light guiding structure S. It can be seen from the comparison between FIG. 2 and FIG. 1 that the biggest difference between the second embodiment of the present invention and the first embodiment is that in the second embodiment, the light guide plate 1 has a connection to the long side 11 and the short side 12. The illuminating unit 13 includes a third illuminating module 23 disposed on a side of the slanting side 13 of the light guide plate 1. The third illuminating module 23 includes a third circuit board 230 and a plurality of The third light-emitting element 231 is disposed on the third circuit substrate 230 and faces the oblique side 13 of the light guide plate 1. For example, the number of the plurality of third light-emitting elements 231 used may conform to the following formula: N3 = (1.43 × 10 -3 ) X ~ (4.8 × 10 -3 ) X, where N3 is a plurality of third light-emitting elements The number of the 231 used, X is the length of the long side of the long side 11 of the light guide plate 1 (the length X of the long side of the second embodiment will be smaller than the length X of the long side of the first embodiment), the unit of the length In millimeters.
藉此，依據上述第二實施例的“雙邊設置光源模式”來實現本發明的導光結構S時，在導光板1能夠達到一特定標準導光均勻度的條件設定下，本發明不僅可以有效減少LED所使用的總顆數及有效減少MCPCB所使用的總長度，以達到降低成本及環保節能的目的，並且也可通過鄰近斜側邊13的第三發光模組23的設計，以有效解決角落暗帶及減少暗亮差的問題，進而更加提升導光板1的導光均勻度。Therefore, when the light guiding structure S of the present invention is implemented according to the "bilaterally disposed light source mode" of the second embodiment described above, the present invention can be effectively effective only under the condition that the light guiding plate 1 can achieve a specific standard light guiding uniformity. The total number of LEDs used is reduced and the total length used by the MCPCB is effectively reduced to achieve cost reduction, environmental protection and energy saving, and can also be effectively solved by designing the third illumination module 23 adjacent to the oblique side 13 The dark band in the corner and the problem of reducing the darkness and the difference in brightness, thereby further improving the light guiding uniformity of the light guide plate 1.
〔第三實施例〕[Third embodiment]
請參閱圖3所示，本發明第三實施例提供一種導光結構S。由圖3與圖1的比較可知，本發明第三實施例與第一實施例最大的差別在於：在第三實施例中，導光板1具有一連接於長側邊11及短側邊12之間的斜側邊13，並且發光單元2包括一設置在導光板1的斜側邊13的一旁的第二發光模組22，其中第二發光模組22包括一第二電路基板220及多個設置於第二電路基板220上且面向導光板1的斜側邊13的第二發光元件221。舉例來說，多個第一發光元件211及多個第二發光元件221所使用的顆數，可以分別符合下列公式：N1=(1.42×10-3 )X~(5.7×10-3 )X及N2=0.036Y~0.02Y，其中N1為多個第一發光元件211所使用的顆數，N2為多個第二發光元件221所使用的顆數，X為導光板1的長側邊11的長側邊長度(第二實施例的長側邊長度X會小於第一實施例的長側邊長度X)，Y為導光板1的短側邊12的短側邊長度(第二實施例的短側邊長度Y會小於第一實施例的短側邊長度Y)，長度的單位皆為毫米。Referring to FIG. 3, a third embodiment of the present invention provides a light guiding structure S. It can be seen from the comparison between FIG. 3 and FIG. 1 that the biggest difference between the third embodiment of the present invention and the first embodiment is that in the third embodiment, the light guide plate 1 has a connection to the long side 11 and the short side 12. The second light-emitting module 22 includes a second circuit substrate 220 and a plurality of light-emitting units 22, and the second light-emitting module 22 includes a second circuit board 220 and a plurality of light-emitting units The second light-emitting element 221 is disposed on the second circuit substrate 220 and faces the oblique side 13 of the light guide plate 1. For example, the number of the plurality of first light-emitting elements 211 and the plurality of second light-emitting elements 221 can respectively satisfy the following formula: N1=(1.42×10 -3 )X~(5.7×10 -3 )X And N2=0.036Y~0.02Y, wherein N1 is the number of the plurality of first light-emitting elements 211, N2 is the number of the plurality of second light-emitting elements 221, and X is the long side 11 of the light guide plate 1. The length of the long side (the length X of the long side of the second embodiment will be smaller than the length X of the long side of the first embodiment), and Y is the length of the short side of the short side 12 of the light guide plate 1 (second embodiment) The short side length Y will be smaller than the short side length Y) of the first embodiment, and the length units are all in millimeters.
藉此，依據上述第三實施例的“雙邊設置光源模式”來實現本發明的導光結構S時，在導光板1能夠達到一特定標準導光均勻度的條件設定下，本發明不僅可以有效減少LED所使用的總顆數及有效減少MCPCB所使用的總長度，以達到降低成本及環保節能的目的，並且也可通過鄰近斜側邊13的第二發光模組22的設計，以有效解決角落暗帶及減少暗亮差的問題，進而更加提升導光板1的導光均勻度。Therefore, when the light guiding structure S of the present invention is implemented according to the "bilaterally disposed light source mode" of the third embodiment, the present invention can be effectively effective only under the condition that the light guiding plate 1 can achieve a specific standard light guiding uniformity. The total number of LEDs used is reduced and the total length used by the MCPCB is effectively reduced to achieve cost reduction, environmental protection and energy saving, and can also be effectively solved by designing the second illumination module 22 adjacent to the oblique side 13 The dark band in the corner and the problem of reducing the darkness and the difference in brightness, thereby further improving the light guiding uniformity of the light guide plate 1.
