Abstract
Description
本發明是有關於一種導光棒及應用其之背光模組,且特別是有關於一種產生多個出光源之導光棒及應用其之背光模組。The invention relates to a light guide bar and a backlight module using the same, and particularly relates to a light guide bar for generating a plurality of light sources and a backlight module using the same.
請參照第1圖,其繪示習知導光棒之示意圖。導光棒100包括二光源108、一棒體110、多個擴散粒子102及一反射膜106。擴散粒子102係填充於棒體110內。反射膜106係貼附在棒體110之一外表面104,以將接觸到反射膜106之光線L反射回導光棒100內,以避免光線L之散失。擴散粒子102則用以使光源108之光線L在接觸到擴散粒子102後,將之導出棒體110之外,被導出之光線即光線La,以達到照明或特定的光學用途。Please refer to FIG. 1 , which shows a schematic diagram of a conventional light guiding rod. The light guide bar 100 includes two light sources 108, a rod body 110, a plurality of diffusion particles 102, and a reflection film 106. The diffusion particles 102 are filled in the rod 110. The reflective film 106 is attached to an outer surface 104 of the rod 110 to reflect the light L contacting the reflective film 106 back into the light guiding rod 100 to avoid loss of the light L. The diffusing particles 102 are used to cause the light L of the light source 108 to be led out of the diffusing particles 102 and then to be led out of the rod 110, and the light to be extracted, that is, the light La, to achieve illumination or specific optical use.
然而,二個光源108卻只能產生一個出光源La,其用途係被侷限。此外,由於出光區域的範圍較大(即大面積出光),導致整體出光強度較弱,因此出光光線之指向性也不佳。However, the two light sources 108 can only produce one source La, and its use is limited. In addition, since the range of the light exiting region is large (that is, a large area of light is emitted), the overall light output intensity is weak, and thus the directivity of the light exiting light is not good.
本發明係有關於一種導光棒及應用其之背光模組。藉由於導光棒之棒體上設置多個出光結構,達到藉由少數個入光源而能產生多個出光源。並且,由於單一出光源之出光面積縮小,使得光線強度變強,指向性因此變得較佳。如此,便可達到特定照射用途。The invention relates to a light guiding rod and a backlight module using the same. Since a plurality of light-emitting structures are disposed on the rod of the light guiding rod, a plurality of light sources can be generated by a small number of light sources. Further, since the light-emitting area of the single light source is reduced, the light intensity is increased, and the directivity is thus improved. In this way, specific illumination uses can be achieved.
根據本發明之一方面,提出一種導光棒。導光棒包括一棒體、一第一光源及一反射元件。棒體具有多個出光結構、一第一端面及一外表面。出光結構係設置於外表面上且彼此之間不相連接。第一光源對應第一端面設置,其用以發射一第一光線進入棒體內。反射元件係包圍外表面且具有多個透光開口,該些透光開口分別露出該些出光結構。藉此,第一光線接觸到反射元件反射回棒體內後,再透過接觸到出光結構導出棒體。According to an aspect of the invention, a light guiding rod is proposed. The light guiding rod comprises a rod body, a first light source and a reflecting element. The rod body has a plurality of light emitting structures, a first end surface and an outer surface. The light exiting structures are disposed on the outer surface and are not connected to each other. The first light source is disposed corresponding to the first end surface for emitting a first light into the rod body. The reflective element surrounds the outer surface and has a plurality of light transmissive openings that respectively expose the light exiting structures. Thereby, the first light comes into contact with the reflective element and is reflected back into the rod body, and then the rod is guided through the light-emitting structure.
根據本發明之另一方面,提出一種背光模組。背光模組包括一導光板及一導光棒。導光棒係鄰近導光板設置。導光棒包括一棒體、一第一光源及一反射元件。棒體具有數個出光結構、一第一端面以及一外表面。其中該些出光結構設置於對應入射面之外表面上,且彼此之間係不相連接。第一光源對應第一端面設置,用以發射一第一光線進入棒體內。反射元件包圍外表面,且具有數個透光開口,其中該些透光開口分別露出該些出光結構。藉此,第一光線接觸到反射元件反射回棒體內後,再透過接觸到出光結構導出棒體至導光板。According to another aspect of the present invention, a backlight module is provided. The backlight module includes a light guide plate and a light guide bar. The light guiding rod is disposed adjacent to the light guide plate. The light guiding rod comprises a rod body, a first light source and a reflecting element. The rod has a plurality of light-emitting structures, a first end surface, and an outer surface. The light-emitting structures are disposed on the outer surfaces of the corresponding incident surfaces and are not connected to each other. The first light source is disposed corresponding to the first end surface for emitting a first light into the rod body. The reflective element surrounds the outer surface and has a plurality of light-transmissive openings, wherein the light-transmissive openings respectively expose the light-emitting structures. Thereby, the first light comes into contact with the reflective element and is reflected back into the rod body, and then passes through the light-emitting structure to lead out the rod body to the light guide plate.
為讓本發明之上述內容能更明顯易懂,下文特舉較佳實施例,並配合所附圖式,作詳細說明如下:In order to make the above-mentioned contents of the present invention more comprehensible, the preferred embodiments are described below, and the detailed description is as follows:
請參照第2圖,其繪示依照本發明第一實施例之導光棒之示意圖。導光棒200包括一棒體204、一反射元件206及一第一光源202。導光棒200之材質係可為透明樹脂材料,例如是聚碳酸酯(polycarbonate,PC)、聚甲基丙烯酸甲酯(polymethyl methacrylate,PMMA)或聚對苯二甲酸乙二酯(polyethylene terephthalate,PET)。Please refer to FIG. 2, which is a schematic view of a light guiding rod according to a first embodiment of the present invention. The light guide bar 200 includes a rod 204, a reflective element 206 and a first light source 202. The material of the light guiding rod 200 may be a transparent resin material, such as polycarbonate (PC), polymethyl methacrylate (PMMA) or polyethylene terephthalate (PET). ).
棒體204具有二個出光結構208及一第一端面210,第一光源202對應第一端面210設置。二個出光結構208設置於棒體204之一外表面214且彼此之間係不相連接。藉此當第一光線L1接觸到反射元件206反射回棒體204內後,再透過接觸到出光結構208導出至棒體204外。其中,棒體204之截面形狀可以是圓形,方形或其它形狀,本實施例之棒體204之截面形狀係以圓形為例作說明。The rod body 204 has two light emitting structures 208 and a first end surface 210. The first light source 202 is disposed corresponding to the first end surface 210. The two light exiting structures 208 are disposed on one of the outer surfaces 214 of the rods 204 and are not connected to each other. Thereby, after the first light L1 is in contact with the reflective element 206 and reflected back into the rod body 204, the light is transmitted to the outside of the rod body 204 through the light-emitting structure 208. The cross-sectional shape of the rod 204 may be a circular shape, a square shape or the like. The cross-sectional shape of the rod 204 of the present embodiment is exemplified by a circular shape.
如第2圖所示,只要使用一個光源,例如是第一光源202就能產生多個點光源或線光源,例如產生從二個出光結構208出光之光線Lb的效果。並且,出光結構208可設置於一預設位置,以達到預設方向出光之特效。如此,本實施例之導光棒係可應用於一美術產品之照明,以特定方向射向美術品,更能顯示出美術品之特色。並且,由於出光結構208之出光面積較小,因此出光強度相對較大且較集中而達到較佳之指向性。As shown in Fig. 2, as long as one light source is used, for example, the first light source 202 can generate a plurality of point light sources or line light sources, for example, an effect of generating light Lb emitted from the two light exiting structures 208. Moreover, the light-emitting structure 208 can be disposed at a preset position to achieve the special effect of the light exiting in the preset direction. In this way, the light guiding rod of the embodiment can be applied to the illumination of an art product, and can be directed to the art product in a specific direction, and can further display the characteristics of the art product. Moreover, since the light-emitting structure 208 has a small light-emitting area, the light-emitting intensity is relatively large and concentrated to achieve better directivity.
此外,出光結構208的數目也可以是二個以上且可平均散佈於外表面214,以達到整個周緣都有光源出光之效果。更進一步地說,本實施例之出光結構208的數目並非用以限定本發明。In addition, the number of light-emitting structures 208 may also be two or more and may be evenly distributed on the outer surface 214 to achieve the effect of light output from the entire periphery. Furthermore, the number of light-emitting structures 208 of the present embodiment is not intended to limit the invention.
如第2圖所示,反射元件206,例如是一反射膜,包圍外表面214。其中,反射膜係以貼附方式設置於外表面214上。反射元件206具有二個透光開口216,二個透光開口216分別露出二個出光結構208。反射元件206係用以當第一光線L1接觸到反射元件206時,將第一光線L1反射回棒體204內。如此,不會有光線散失至棒體204外,以增加光源效率。其中,透光開口216之數目可配合出光結構208之數目。As shown in FIG. 2, the reflective element 206 is, for example, a reflective film that surrounds the outer surface 214. The reflective film is disposed on the outer surface 214 in an attached manner. The reflective element 206 has two light transmissive openings 216, and the two light transmissive openings 216 respectively expose the two light exiting structures 208. The reflective element 206 is configured to reflect the first light L1 back into the rod 204 when the first light L1 contacts the reflective element 206. In this way, no light is lost outside the rod 204 to increase the efficiency of the light source. The number of the light-transmissive openings 216 can match the number of the light-emitting structures 208.
此外,反射元件206亦可為一反射層(未繪示),係以塗佈方式設置於外表面214上。或者,請參照第3圖,其繪示本發明另一實施例之反射元件示意圖。反射元件可為一反射罩220,其與棒體204之間保持一間隙S。為達到反射效果,反射罩220之材質可為一具有高反射率之金屬。或者,可於反射罩220之內表面設置一高反射率之材質,以達到反射第一光線L1之功用。In addition, the reflective element 206 can also be a reflective layer (not shown) disposed on the outer surface 214 in a coating manner. Alternatively, please refer to FIG. 3, which is a schematic view of a reflective element according to another embodiment of the present invention. The reflective element can be a reflector 220 that maintains a gap S with the rod 204. In order to achieve the reflection effect, the material of the reflector 220 can be a metal with high reflectivity. Alternatively, a high reflectivity material may be disposed on the inner surface of the reflector 220 to achieve the function of reflecting the first light L1.
請參照第4圖,其繪示第2圖中往方向4A-4A’觀看到的棒體及反射元件示意圖。出光結構208的剖面輪廓係為三角形。然此非用以限制本發明,出光結構208的剖面輪廓亦可為多邊形、弧形、圓形之一部份或橢圓形之一部份。或者,出光結構208的剖面輪廓也可以是三角形、多邊形、圓形、弧形與橢圓形之任意組合。更進一步地說,只要能達到出光之效果,出光結構208的剖面輪廓並無限定。因此,出光結構208也可以是一粗糙面,其剖面輪廓係呈不規則狀。只要能達到出光效果之出光結構之剖面輪廓,皆屬本發明之範圍。Referring to Fig. 4, there is shown a schematic view of the rod and the reflecting member viewed in the direction 4A-4A' in Fig. 2. The cross-sectional profile of the light exiting structure 208 is triangular. However, this is not intended to limit the present invention, and the cross-sectional profile of the light-emitting structure 208 may also be a polygonal portion, an arc, a part of a circle, or a part of an ellipse. Alternatively, the cross-sectional profile of the light exiting structure 208 can also be any combination of a triangle, a polygon, a circle, an arc, and an ellipse. Furthermore, the cross-sectional profile of the light-emitting structure 208 is not limited as long as the light-emitting effect can be achieved. Therefore, the light-emitting structure 208 can also be a rough surface whose profile is irregular. It is within the scope of the invention to have a cross-sectional profile of the light-emitting structure that achieves the light-emitting effect.
此外,第一光源202也可以是一發射不可見光之光源,例如是紫外光源。此時,棒體204係包括多個螢光粒子(未繪示),係分佈於棒體204內。當紫外光源所發射之紫外光線照射到螢光粒子時,螢光粒子便激發出光線。更進一步地說,第一光源202可為一發射可見光之光源或一發射不可見光之光源。In addition, the first light source 202 can also be a light source that emits invisible light, such as an ultraviolet light source. At this time, the rod 204 includes a plurality of fluorescent particles (not shown) distributed in the rod 204. When the ultraviolet light emitted by the ultraviolet light source is irradiated to the fluorescent particles, the fluorescent particles excite the light. Furthermore, the first light source 202 can be a light source that emits visible light or a light source that emits invisible light.
此外,在另一實施態樣之導光棒中,棒體也可以包括多個擴散粒子。請參照第5圖,其繪示本發明另一實施例之棒體更包括擴散粒子之示意圖。導光棒300之棒體304更包括擴散粒子302,擴散粒子302分佈於棒體304內。Further, in another embodiment of the light guiding rod, the rod may also include a plurality of diffusing particles. Please refer to FIG. 5, which illustrates a schematic diagram of a rod body further including diffusion particles according to another embodiment of the present invention. The rod 304 of the light guiding rod 300 further includes diffusing particles 302, and the diffusing particles 302 are distributed in the rod 304.
請參照第6圖,其繪示依照本發明第二實施例之導光棒之示意圖。第二實施例與第一實施例不同之處在於,第二實施例之導光棒400更包括一第二光源402。其餘相同之處係沿用同標號,於此便不再贅述。Please refer to FIG. 6, which is a schematic view of a light guiding rod according to a second embodiment of the present invention. The second embodiment is different from the first embodiment in that the light guide bar 400 of the second embodiment further includes a second light source 402. The rest of the same points are the same reference numerals, and will not be repeated here.
棒體204更具有一對應於第一端面210之第二端面212,第二光源402對應第二端面212設置,用以發射一第二光線L2進入棒體204內。導光棒400之一反射元件404露出第二端面212,以讓第二光線L2進入棒體204內。其中,反射元件404係可為一反射膜,其以貼附方式設置於棒體204之外表面214上。The rod body 204 further has a second end surface 212 corresponding to the first end surface 210. The second light source 402 is disposed corresponding to the second end surface 212 for emitting a second light L2 into the rod body 204. One of the reflective elements 404 of the light guiding rod 400 exposes the second end surface 212 to allow the second light L2 to enter the rod 204. The reflective element 404 can be a reflective film disposed on the outer surface 214 of the rod 204 in an attached manner.
本實施例之導光棒400係使用二個光源,使得由出光結構208射出之光線Lc更加強烈。The light guide bar 400 of the present embodiment uses two light sources such that the light Lc emitted by the light exiting structure 208 is more intense.
請參照第7圖,其繪示依照本發明第三實施例之背光模組之示意圖。第三實施例與第二實施例不同之處在於,第三實施例係將本發明之導光棒應用於一背光模組500。Please refer to FIG. 7 , which is a schematic diagram of a backlight module according to a third embodiment of the present invention. The third embodiment is different from the second embodiment in that the third embodiment applies the light guide bar of the present invention to a backlight module 500.
背光模組500包括導光板502及導光棒504,導光棒504鄰近導光板502設置。導光棒504包括一棒體506及一反射元件508。棒體506具有三個出光結構510及相對之一第一端面512與一第二端面514。第一光源202對應第一端面512,第二光源402對應第二端面514設置。導光板502具有一入射面520,出光結構510設置於對應入射面520之外表面516上且彼此之間不相連接。其中,第一光線L1及第二光線L2接觸到反射元件508後反射回棒體506內,再透過接觸出光結構510導出棒體506至導光板502。The backlight module 500 includes a light guide plate 502 and a light guide bar 504 disposed adjacent to the light guide plate 502. The light guide bar 504 includes a rod 506 and a reflective element 508. The rod 506 has three light exiting structures 510 and one of the first end faces 512 and a second end face 514. The first light source 202 corresponds to the first end surface 512 , and the second light source 402 is disposed corresponding to the second end surface 514 . The light guide plate 502 has an incident surface 520, and the light exiting structures 510 are disposed on the outer surface 516 of the corresponding incident surface 520 and are not connected to each other. The first light L1 and the second light L2 are in contact with the reflective element 508 and then reflected back into the rod body 506, and then the light output structure 510 is used to lead the rod body 506 to the light guide plate 502.
反射元件508,例如是一反射膜,係包圍外表面516並露出第一端面512及第二端面514。其中,反射膜係以貼附方式設置於外表面516上。反射元件508具有三個透光開口518。其中,透光開口518之數目可配合出光結構510之數目,三個透光開口518分別露出三個出光結構510。反射元件508用以當第一光線L1及第二光線L2接觸到反射元件508時,將第一光線L1及第二光線L2反射回棒體506內。如此,便不會有光線散失至棒體506外,以增加光源效率。The reflective element 508, for example, a reflective film, surrounds the outer surface 516 and exposes the first end surface 512 and the second end surface 514. The reflective film is disposed on the outer surface 516 in an attached manner. Reflective element 508 has three light transmissive openings 518. The number of the light-transmissive openings 518 can match the number of the light-emitting structures 510, and the three light-transmissive openings 518 respectively expose the three light-emitting structures 510. The reflective element 508 is configured to reflect the first light L1 and the second light L2 back into the rod 506 when the first light L1 and the second light L2 contact the reflective element 508. In this way, no light is lost outside the rod 506 to increase the efficiency of the light source.
於本實施中,只需要二個光源,即第一光源202及第二光源402,就能產生二個以上之點光源或線光源射向導光板502,例如是產生三道光線Le射向導光板502。In this embodiment, only two light sources, namely the first light source 202 and the second light source 402, are required to generate two or more point light sources or line light sources to illuminate the light guide plate 502, for example, to generate three rays of light to guide the light guide plate 502. .
雖然本實施例之光源係以二個,即第一光源202及第二光源402為例作說明,然於其它實施例中,背光模組500之導光棒504也可以只有第一光源202與第二光源402其中一者。如此,同樣可達到產生多個點光源或線光源的功效。Although the light source of the present embodiment is exemplified by two, that is, the first light source 202 and the second light source 402, in other embodiments, the light guide bar 504 of the backlight module 500 may only have the first light source 202 and One of the second light sources 402. In this way, the effect of generating a plurality of point light sources or line light sources can also be achieved.
雖然,本實施例之導光棒504之出光結構510係以三個為例作說明,然於其它實施例中,導光棒504之出光結構510也可以是三個以上,其數目並不受本實施例之限制。The light-emitting structure 510 of the light guide bar 504 of the present embodiment is exemplified by three. However, in other embodiments, the light-emitting structure 510 of the light guide bar 504 may be three or more, and the number thereof is not affected. The limitations of this embodiment.
本發明上述實施例所揭露之導光棒及應用之背光模組,具有多項優點,以下僅列舉部分優點說明如下:The light guide bar and the applied backlight module disclosed in the above embodiments of the present invention have a plurality of advantages, and only some of the advantages described below are as follows:
(1).出光結構係分開地設置於棒體上,使得藉由少數個光源就能產生多個點光源或線光源。(1) The light-emitting structure is separately disposed on the rod so that a plurality of point light sources or line light sources can be produced by a small number of light sources.
(2).由於出光結構出光之面積變小,使得光線強度相對變強,指向性因此變得較佳。(2). Since the area of the light outgoing structure becomes smaller, the light intensity is relatively stronger, and the directivity is thus better.
綜上所述,雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明。本發明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,當可作各種之更動與潤飾。因此,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。In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention.
