In the present embodiment, the package housing ==4ί:Τΐ]Ϊ 1244, and the two extension walls 1244 respectively shield a portion of the light exit surface 114 U and a portion of the bottom surface 122 of the hemp m λαu. Therefore, the portion of the light ray that is emitted from the illuminating element 122 that does not directly enter the light guide plate UG is reflected by the extension 1244 and is secreted into the light guide plate 11 〇. In this way, the light source mode and the Γ〇Γ effectively use the light emitted by the point source 120, and the light leakage phenomenon can be readable. As a result of the simulation, it can be seen that there is an extension wall (4) light _, _, the light source module 1GG having the extension wall ^ in this embodiment can improve the light extraction efficiency by 7% to 11%.
鬌 另外，本實施例的導光板110夾於兩延伸壁1244之 間。所以，點_ 120在垂直出光面114的方向(也就是ζ 方向)上不容易有對位不良關題。也就是說，延伸壁ΐ244 在結構上可提供點絲12G與導光板11()之間相互干涉的 設計。因此，組裝光源模組觸時，不需特別在z方向上 以其他的治具進行對位而有助於簡化組裝製程。當然，光 源模組100也因為對位精準度提升而具有較高的良率。 一具體而言’目1B緣示為本創作之—實施例的導光板 之示意圖。請同時參照圖1A與圖1B，導光板11〇實質上 具有-入光結構118’以定義出入光面116。入光結構ιΐ8 例如是一波浪狀的結構設計，而有助於將光線導入導光板 U0。不過’人光結構118的設計也可以是所屬技術領域中 7 M379771 的其他結構設計，例如其他形狀的凹凸結構。實際上，本 實施例的延伸壁1244包覆住入光結構118可以將又射於延 伸壁1244的光線反射至導光板丨1〇以達到提高光利用率的 功效。 詳言之，延伸壁1244可與本體1242直接連接在一 起，且封裝殼體124實際上為—體成型的設計。也就是說， 延伸壁1244 *需要以額外的製程組裝或是貼附於本體 1242上。製作封裝殼體124時只需更改成型用的模具設計 就可以完成有延伸壁1244的封裝殼體124。另外，本實施 例的延伸壁1244的結構是平行出光面114而設計。不過， 延伸壁1244的結構可以是其他的型態。 舉例而&，圖2A至圖2D繪示為本創作之多個延伸 壁的剖面設計。值得一提的是，光源模組1〇〇中，延伸壁 1244的設計可以是以下延伸壁1244A〜1244D其中一種’ 且二延伸壁1244可以具有不同的結構設計或是相同的結 構設計。請先參照圖2A與圖2B ’由剖面圖可知，連接於 本體1242的延伸壁1244A與1244B在厚度上的變化例如 是由本體1242向外逐漸變薄❶另外，延伸壁i244A的内 側為平面P，而延伸壁1244B的内側為弧面c。將延伸壁 1244A與1244B的設計應用於圖1A的光源模組100時， 平面P與弧面C例如是位在鄰近導光板11〇的一側。 此外’由圖2C與圖2D可知，延伸壁1244C與1244D 的厚度可以由本體1242向外逐漸變厚，其中延伸壁1244C 的内側為平面P，而延伸壁1244D的内側為派面C。同樣 =，將延伸壁H44C與1244D的設計應用於w u的光源 核組100時’平面P與弧面c例如是接近導光板11〇設置。 九圖3繪不為本創作之另一實施例的光源模組之剖面示 意圖。請參照圖3，光源模組200的組成構件實質1與^ 源松組100的組成構件相同，只是各構件之間的配置關係 不同。光源模組200中，反射板130例如更位於其中丄延 伸壁1244與底面112之間。因此，其中一個延伸壁1244 並未直接接觸導光板110，而是直揍接觸反射板13〇。此 外，電路板140實質上垂直於導光板11〇之底面n2。也 就是說’光源模組100中的點光源120為侧面出光式(side view type)設計’而本實施例的光源模組200中的點光源 120為頂面出光式(top view type)設計。值得一提的是，與 前述實施例相似，光源模組200具有良好的光利用率且構 件之間不易有對位誤差。也就是說，光源模組200具有良 好的品質。 圖4繪示為本創作之又一實施例的光源模組示意圖， 其中僅繪示有點光源與導光板。請參照圖4，光源模組3 0 0 中，光源320具有四延伸壁3244。點光源320與導光板 110組裝在一起時，其中兩延伸壁3244例如遮蔽部份出光 面114以及部份底面112，而另兩延伸壁3244則直接接觸 入光面116。這樣的設計，除了可以反射Z方向上可能產 生的漏光外，還可以反射側向的漏光。也就是說，點光源 320的光線可以更有效地被利用，且光源模組300更不容 易產生漏光現象。 =體 5::===封==: 以:不易有對位誤差產生。因此，本創作的設計有二 於美咼光源模組的組裝良率。 力助 雖然本創作已以實施例揭露如上，然其並非用以阳〜 =之=斤屬技術領域中具有通常知識者，在不‘ 本創作之精砷和_内，t可作些許之更動與_ = 創作之保魏JU當視賴之申請專利範圍所界定者為準。 【圖式簡單說明】 剖 圖1A繪示為本創作之一實施例的光源模組之 面示意圖。 ° 計 意圖 圖1B繪示為本創作之一實施例的導光板之示意圖 圖2八至圖2D繪示為本創作之多個延伸壁的 圖3繪示為本創作之另一實施例的光源模組之剖面厂、 圖4繪示為本創作之又一實施例的光源模組示意圖， 其中僅繪示有點光源與導光板。 ^回 【主要元件符號說明】 100、200、300 :光源模組 M379771 110 :導光板 112 :底面 114 :出光面 116 :入光面 118 :入光結構 120、320 :點光源 122 :發光元件 124 :封裝殼體 126 :透明膠體 130 :反射板 140 :電路板 1242 :本體 1244、1244A、1244B、1244C、1244D、3244 :延伸壁 C :弧面 G :間距 P :平面 Z :方向Further, the light guide plate 110 of the present embodiment is sandwiched between the two extending walls 1244. Therefore, the point _ 120 is not easy to have a misalignment in the direction of the vertical light exit surface 114 (that is, the ζ direction). That is, the extension wall 244 is structurally provided to provide a mutual interference between the dotted wire 12G and the light guide plate 11 (). Therefore, when assembling the light source module, it is not necessary to specifically align with other jigs in the z direction, which helps to simplify the assembly process. Of course, the light source module 100 also has a high yield because of the improved alignment accuracy. A specific view of the light guide plate of the present embodiment is shown. Referring to FIG. 1A and FIG. 1B simultaneously, the light guide plate 11A has a light-into-light structure 118' to define the light-incident surface 116. The light-incident structure ιΐ8 is, for example, a wavy structural design that helps to introduce light into the light guide plate U0. However, the design of the human light structure 118 can also be other structural designs of the 7 M379771 in the prior art, such as bump structures of other shapes. In fact, the extension wall 1244 of the present embodiment encloses the light-incorporating structure 118 to reflect the light incident on the extension wall 1244 to the light guide plate 〇1〇 to improve the light utilization efficiency. In particular, the extension wall 1244 can be directly coupled to the body 1242, and the package housing 124 is actually a body-formed design. That is, the extension wall 1244* needs to be assembled or attached to the body 1242 in an additional process. When the package housing 124 is fabricated, the package housing 124 having the extension wall 1244 can be completed by simply changing the mold design for molding. Further, the structure of the extension wall 1244 of this embodiment is designed to be parallel to the light exit surface 114. However, the structure of the extension wall 1244 can be other types. For example, & Figure 2A to Figure 2D illustrate the cross-sectional design of a plurality of extension walls of the present invention. It is worth mentioning that in the light source module 1 ,, the design of the extension wall 1244 may be one of the following extension walls 1244A to 1244D and the two extension walls 1244 may have different structural designs or the same structural design. Referring to FIG. 2A and FIG. 2B, the cross-sectional view shows that the thickness of the extension walls 1244A and 1244B connected to the body 1242 is gradually thinned outward by the body 1242. In addition, the inner side of the extension wall i244A is a plane P. And the inner side of the extension wall 1244B is a curved surface c. When the design of the extension walls 1244A and 1244B is applied to the light source module 100 of FIG. 1A, the plane P and the curved surface C are, for example, located on the side adjacent to the light guide plate 11A. Further, as can be seen from Fig. 2C and Fig. 2D, the thickness of the extension walls 1244C and 1244D can be gradually thickened outwardly from the body 1242, wherein the inner side of the extension wall 1244C is a plane P, and the inner side of the extension wall 1244D is a plane C. Similarly, when the design of the extension walls H44C and 1244D is applied to the light source core group 100 of the u, the plane P and the arc surface c are, for example, disposed close to the light guide plate 11A. Figure 3 is a cross-sectional view of a light source module not another embodiment of the present invention. Referring to FIG. 3, the constituent members 1 of the light source module 200 are the same as the constituent members of the source group 100, except that the arrangement relationship between the members is different. In the light source module 200, the reflector 130 is, for example, located between the extended wall 1244 and the bottom surface 112. Therefore, one of the extension walls 1244 does not directly contact the light guide plate 110, but directly contacts the reflection plate 13A. In addition, the circuit board 140 is substantially perpendicular to the bottom surface n2 of the light guide plate 11A. That is, the point source 120 in the light source module 100 is a side view type design, and the point source 120 in the light source module 200 of the present embodiment is a top view type design. It is worth mentioning that, similar to the foregoing embodiment, the light source module 200 has good light utilization efficiency and there is no easy alignment error between the components. That is to say, the light source module 200 has a good quality. FIG. 4 is a schematic diagram of a light source module according to still another embodiment of the present invention, wherein only a somewhat light source and a light guide plate are illustrated. Referring to FIG. 4, in the light source module 300, the light source 320 has four extending walls 3244. When the point light source 320 is assembled with the light guide plate 110, the two extension walls 3244 shield the partial light exit surface 114 and the partial bottom surface 112, for example, and the other two extension walls 3244 directly contact the light incident surface 116. Such a design, in addition to reflecting light leakage that may occur in the Z direction, can also reflect lateral light leakage. That is to say, the light of the point source 320 can be utilized more effectively, and the light source module 300 is less prone to light leakage. = body 5::===封==: To: It is not easy to have a registration error. Therefore, the design of this creation has the assembly yield of the US-based light source module. Although the creation has been exposed as above in the example, it is not used for the general knowledge of the technology in the technical field of the genius, and it is not possible to make some changes in the essence of this creation. And _ = Creation of Wei Wei is determined by the scope of the patent application.
