光源模块Light source module

技术领域technical field

本实用新型是有关于一种光源模块，且特别是有关于一种利用固定件固定导光板的光源模块。The utility model relates to a light source module, in particular to a light source module using a fixing piece to fix a light guide plate.

背景技术Background technique

发光二极管(Light-Emitting Diode；LED)是一常见的点光源，其具有高亮度、省电及质轻等优点，导致LED广泛应用于各种生活用品的发光源中。然而，当LED欲应用于大面积的发光源或液晶显示器时，常须设置大量的LED来使其光度均匀，导致成本增加。Light-emitting diode (Light-Emitting Diode; LED) is a common point light source, which has the advantages of high brightness, power saving and light weight, so that LED is widely used in light sources of various daily necessities. However, when LEDs are to be applied to large-area light sources or liquid crystal displays, a large number of LEDs must be provided to make the luminosity uniform, resulting in increased cost.

目前常见的作法是将导光板与LED两者相结合，利用导光板将点光源LED所发出的光，引导成面光源。如此可解决上述的缺陷，使得LED的应用范围更广。此外亦可减小发光源的体积，使得发光源可应用于更轻薄的产品。A common practice at present is to combine the light guide plate and the LED, and use the light guide plate to guide the light emitted by the point light source LED into a surface light source. In this way, the above-mentioned defects can be solved, so that the application range of the LED is wider. In addition, the volume of the light emitting source can also be reduced, so that the light emitting source can be applied to lighter and thinner products.

导光板是以聚甲基丙烯酸甲酯制作，其热变形温度是70℃至90℃。当其过于靠近光源模块中的点光源时，容易因点光源所发出的热，产生熔融。因此导光板与点光源间须间隔一距离(Air Gap)，使得导光板与点光源间具有空气，通过空气的阻隔，减少传递至导光板的热能。当此距离过小时，导光板易受热而熔融，而当距离过大时，导光板的效率不佳。The light guide plate is made of polymethyl methacrylate, and its heat distortion temperature is 70°C to 90°C. When it is too close to the point light source in the light source module, it is easy to melt due to the heat emitted by the point light source. Therefore, there must be a distance (Air Gap) between the light guide plate and the point light source, so that there is air between the light guide plate and the point light source, and the heat energy transmitted to the light guide plate can be reduced through the barrier of air. When the distance is too small, the light guide plate is easily heated and melted, and when the distance is too large, the efficiency of the light guide plate is not good.

已知技术中，对于导光板于光源模块中的固定方式，常通过设计导光板和框架的结构，利用两者的结构相嵌合，来达到固定的目的。或者，透过设计导光板的结构，使其具有沟槽、孔洞等特殊结构，再使用额外附加的定位柱、螺钉等固定件来固定导光板。In the known technology, for the way of fixing the light guide plate in the light source module, the structure of the light guide plate and the frame is usually designed, and the two structures are used to fit together to achieve the purpose of fixing. Alternatively, by designing the structure of the light guide plate so that it has special structures such as grooves and holes, the light guide plate is fixed with additional fixing elements such as positioning posts and screws.

然而光源模块的需求渐趋轻薄，对于框架的边框亦要求窄小，使得上述的固定件有外露的缺点。此外，导光板或框架的结构设计，亦增加制造成本或降低导光板对于各种光源模块的通用性。当额外附加的固定件使用于大尺寸的光源模块时，其固定件提供的支撑力不足，易使得导光板容易产生晃动，碰撞点光源。However, the demand for the light source module is becoming lighter and thinner, and the frame frame is also required to be narrow, so that the above-mentioned fixing parts have the disadvantage of being exposed. In addition, the structural design of the light guide plate or the frame also increases the manufacturing cost or reduces the versatility of the light guide plate for various light source modules. When the additional fixing part is used for a large-sized light source module, the supporting force provided by the fixing part is insufficient, which may easily cause the light guide plate to shake and collide with the point light source.

请参考图1，图1是绘示依照本实用新型一实施例的一种光源模块的爆炸图。此光源模块10包含框架100、导光板400、多个第一固定件310与第一发光条210。在本实用新型的一实施例中，此光源模块10的框架100至少包含背板101、第一侧板102与第二侧板104。第一侧板102与第二侧板104是立设于背板101相对的二侧。在一例子中，此光源模块10还可选择性包含第三侧板106与第四侧板108，第三侧板106与第四侧板108是立设于背板101相对的另二侧。第一侧板102具有多个第一孔洞102a。Please refer to FIG. 1 . FIG. 1 is an exploded view illustrating a light source module according to an embodiment of the present invention. The light source module 10 includes a frame 100 , alight guide plate 400 , a plurality of first fixingparts 310 and afirst light strip 210 . In an embodiment of the present invention, the frame 100 of the light source module 10 at least includes aback panel 101 , afirst side panel 102 and asecond side panel 104 .

Thefirst side panel 102 has a plurality offirst holes 102a.

上述的导光板400是设置于框架100中。在本实用新型的一例子中，导光板400是一均匀的平板结构。此导光板400可不须作其它用以固定的结构设计，例如：沟槽、孔洞、凹陷等结构设计，如此使得导光板400可适用于各种光源模块且简化光源模块的制造流程。导光板400包含第一入光面401。在另一实施例中，导光板400可根据光源装置的数量而进一步包含第二入光面402，或更多的入光面。第一入光面401与第二入光面402可位于导光板400相对的二侧。The aforementionedlight guide plate 400 is disposed in the frame 100 . In an example of the present invention, thelight guide plate 400 is a uniform flat structure. Thelight guide plate 400 does not need other fixed structural designs, such as grooves, holes, depressions, etc., so that thelight guide plate 400 can be applied to various light source modules and simplify the manufacturing process of the light source modules. Thelight guide plate 400 includes a firstlight incident surface 401 . In another embodiment, thelight guide plate 400 may further include a secondlight incident surface 402 or more light incident surfaces according to the number of light source devices. The firstlight incident surface 401 and the secondlight incident surface 402 may be located on opposite sides of thelight guide plate 400 .

上述的第一发光条210是设置于第一侧板102上。在一实施例中，第一发光条210包含第一电路板211、多个第一点光源212、与相对应第一孔洞102a的多个第二孔洞211a。这些第一点光源212是设置在第一电路板211上，且电性连接第一电路板211。第一点光源212的发光面210a是朝向第一入光面401。如图2所示，每一个第二点光源212具有第一厚度212a，且每个第一点光源212与导光板400间具有第一距离401a。这些第二孔洞211a则穿设于第一电路板211中。在一例子中，这些第一点光源212是发光二极管、雷射二极管、或上述点光源的组合。The above-mentionedfirst light strip 210 is disposed on thefirst side panel 102 . In one embodiment, thefirst light strip 210 includes afirst circuit board 211 , a plurality of first pointlight sources 212 , and a plurality ofsecond holes 211 a corresponding to thefirst holes 102 a. The first pointlight sources 212 are disposed on thefirst circuit board 211 and electrically connected to thefirst circuit board 211 . The light-emittingsurface 210 a of the first pointlight source 212 faces the first light-incident surface 401 . As shown in FIG. 2 , each second pointlight source 212 has afirst thickness 212 a, and each first pointlight source 212 has afirst distance 401 a from thelight guide plate 400 . Thesecond holes 211 a are formed in thefirst circuit board 211 . In one example, the first pointlight sources 212 are light emitting diodes, laser diodes, or a combination of the above point light sources.

第一固定件310是设置于导光板400与第一发光条210之间。每一个第一固定件310包含第一接合部312与第一固定部314。此第一固定部314是接合于第一接合部312。这些第一接合部312是分别对应穿透第一发光条210的第二孔洞211a，且对应嵌合于第一侧板102的第一孔洞102a中。如此，通过第一固定件310，可将第一发光条210固定于框架100的第一侧板102上。Thefirst fixing member 310 is disposed between thelight guide plate 400 and thefirst light strip 210 . Each first fixingpart 310 includes a firstjoint part 312 and afirst fixing part 314 . Thefirst fixing portion 314 is engaged with the first engagingportion 312 . The firstjoint portions 312 respectively penetrate through thesecond holes 211 a of thefirst light strip 210 and are correspondingly fitted into thefirst holes 102 a of thefirst side plate 102 . In this way, thefirst lighting bar 210 can be fixed on thefirst side panel 102 of the frame 100 through the first fixingmember 310 .

在一例子中，第一接合部312与第一孔洞102a的嵌合可以螺合、紧配合、卡固、或上述固定方法的组合来达成。例如：请参考图2，第一接合部312的一外侧具有第一螺纹结构312a，且第一孔洞102a具有第二螺纹结构102b，其中第一螺纹结构312a与第二螺纹结构102b是互相螺合固定。In one example, the fitting of the first engagingportion 312 and thefirst hole 102a can be achieved by screwing, tight fitting, clamping, or a combination of the above-mentioned fixing methods. For example: Please refer to FIG. 2 , an outer side of the first engagingportion 312 has afirst thread structure 312a, and thefirst hole 102a has asecond thread structure 102b, wherein thefirst thread structure 312a and thesecond thread structure 102b are screwed together fixed.

在图2中，第一固定部314接合于第一接合部312，且第一固定部314是设置于第一发光条210与导光板400间。第一固定部314具有第二厚度314a。在一实施例中，第二厚度314a是大于第一点光源212的第一厚度212a。通过第一固定部314的支撑，可避免导光板400碰撞第一点光源212。在另一实施例中，第二厚度314a是等于第一厚度212a加上述的第一距离401a。In FIG. 2 , thefirst fixing portion 314 is bonded to thefirst bonding portion 312 , and thefirst fixing portion 314 is disposed between thefirst light strip 210 and thelight guide plate 400 . Thefirst fixing portion 314 has asecond thickness 314a. In one embodiment, thesecond thickness 314 a is greater than thefirst thickness 212 a of the first pointlight source 212 . With the support of thefirst fixing portion 314 , thelight guide plate 400 can be prevented from colliding with the first pointlight source 212 . In another embodiment, thesecond thickness 314a is equal to thefirst thickness 212a plus the aforementionedfirst distance 401a.

由于第一点光源212与导光板400间具有第一距离401a。因此，第一点光源212与导光板400间有空气的阻隔。通过空气的阻隔，可降低导光板400接受的热能，避免导光板400因热熔融变形，更可兼顾光源模块10的光学效能。Since there is afirst distance 401 a between the first pointlight source 212 and thelight guide plate 400 . Therefore, there is an air barrier between the first pointlight source 212 and thelight guide plate 400 . Through the barrier of air, the heat energy received by thelight guide plate 400 can be reduced, the deformation of thelight guide plate 400 due to heat melting can be avoided, and the optical performance of the light source module 10 can be taken into consideration.

而第一距离401a是随着第一点光源212的功率大小与导光板400的材质不同，而有所变动。当第一距离401a过小时，导光板400易因第一点光源212所发出的热，造成导光板400熔融变形。当第一距离401a小于0时，导光板400会碰撞到这些第一点光源212，造成第一发光条210损坏。而当第一距离401a过大时，导光板400的导光效果不佳，使光源模块10的效能降低。Thefirst distance 401 a varies with the power of the first pointlight source 212 and the material of thelight guide plate 400 . When thefirst distance 401 a is too small, thelight guide plate 400 is easily melted and deformed by the heat generated by the first pointlight source 212 . When thefirst distance 401 a is less than 0, thelight guide plate 400 will collide with the first pointlight sources 212 , causing damage to the firstlight emitting strip 210 . However, when thefirst distance 401 a is too large, the light guiding effect of thelight guide plate 400 is not good, which reduces the efficiency of the light source module 10 .

因此，在本实施例中，通过第一固定件310的第一固定部314的固定支撑，可固定第一距离401a的大小，使得导光板400具有良好的导光效果，亦不因第一点光源212发出的热，产生熔融变形。Therefore, in this embodiment, through the fixed support of the first fixingpart 314 of the first fixingpart 310, the size of thefirst distance 401a can be fixed, so that thelight guide plate 400 has a good light guiding effect, and it is not caused by the first point. The heat emitted from thelight source 212 produces melting deformation.

此外，通过第一固定部314的支撑，可避免导光板400因重力或晃动影响，碰撞第一点光源212，造成第一发光条210破损。而且，通过第一固定部314的固定，可避免导光板400晃动，且可固定第一距离401a的大小。In addition, through the support of thefirst fixing portion 314 , thelight guide plate 400 can be prevented from colliding with the first pointlight source 212 due to gravity or shaking, causing damage to thefirst light strip 210 . Moreover, through the fixing of thefirst fixing portion 314, thelight guide plate 400 can be prevented from shaking, and the size of thefirst distance 401a can be fixed.

由于第一固定件310是设置于第一发光条210与导光板400间，因此第一固定件310可完全被光源模块10的边框所遮蔽。确实解决窄边框的光源模块中，已知技术的固定件外露的缺陷。Since the first fixingpart 310 is disposed between the firstlight emitting strip 210 and thelight guide plate 400 , the first fixingpart 310 can be completely covered by the frame of the light source module 10 . It really solves the defect of the exposed fixing parts in the known technology in the light source module with a narrow frame.

此外，第一固定件310对于大尺寸的导光板400，亦可提供足够的支撑力，可避免导光板400碰撞第一发光条210。In addition, the first fixingmember 310 can also provide sufficient supporting force for the large-sizedlight guide plate 400 to prevent thelight guide plate 400 from colliding with the first light-emittingstrip 210 .

在一例子中，第一固定件310可为高分子材料、金属材料、或上述材料的组合。在另一例子中，第一固定件310可选用可透光或半透光的材质，以避免因第一固定件310的设置，而造成第一点光源212所发出的光受到干扰，导致光源模块10形成暗区。In one example, the first fixingmember 310 can be a polymer material, a metal material, or a combination of the above materials. In another example, the first fixingmember 310 can be made of translucent or semi-transparent material, so as to avoid the interference of the light emitted by the first pointlight source 212 due to the setting of the first fixingmember 310, causing the light source Module 10 forms a dark zone.

在一例子中，第一接合部312与第一固定部314可为一体成型的结构。在另一例子中，第一接合部312与第一固定部314可不为一体成型的结构，借以增加第一固定件310对于各种光源模块的通用性。例如：第一接合部312先以上述的方式将第一发光条210嵌合于第一孔洞102a中，再依光源模块的需求选用适当的第一固定部314，并将第一固定部314与第一接合部312两者结合。In an example, the first engagingportion 312 and thefirst fixing portion 314 may be integrally formed. In another example, the firstjoint part 312 and the first fixingpart 314 may not be integrally formed, so as to increase the versatility of the first fixingpart 310 for various light source modules. For example: the firstjoint part 312 first fits the first light-emittingstrip 210 into thefirst hole 102a in the above-mentioned manner, and then selects an appropriate first fixingpart 314 according to the requirements of the light source module, and connects the first fixingpart 314 to thefirst hole 102a. The firstjoint part 312 is combined with both.

在一例子中，第一接合部312与第一固定部314可为相同的材料所组成，亦可为相异的材料所组成。在另一例子中，第一固定部314可为两种或两种以上的材料所组成。例如：第一固定部314可为一双层材料结构，内层为金属材质，外层为高分子材料。内层的金属材质可耐受第一点光源212所发出的热。外层的高分子材料则具有耐冲击的特性，可避免导光板400因碰撞造成破损。In one example, the firstjoint portion 312 and thefirst fixing portion 314 may be made of the same material, or may be made of different materials. In another example, thefirst fixing portion 314 may be composed of two or more materials. For example, the first fixingpart 314 can be a double-layer material structure, the inner layer is made of metal material, and the outer layer is made of polymer material. The metal material of the inner layer can withstand the heat emitted by the first pointlight source 212 . The polymer material of the outer layer has impact resistance, which can prevent thelight guide plate 400 from being damaged due to collision.

According to the requirements of the device, thelight source module 10a can also optionally include a plurality ofelastic bodies 500 . Theelastic body 500 is disposed on thesecond side panel 104 of the frame 100 . Theseelastic bodies 500 can exert an elastic force on the secondlight incident surface 402 of thelight guide plate 400 to fix thelight guide plate 400 between the first fixingmember 310 and theelastic bodies 500 . When thelight source module 10a shakes, it can avoid the poor performance of thelight source module 10a caused by the displacement of thelight guide plate 400 . Theseelastic bodies 500 can be springs, thermoplastic polymer elastomers, or a combination of the above materials.

请参考图4，图4是绘示本实用新型的又一实施例的光源模块的俯视图。此光源模块10b的架构大致上与光源模块10的架构相同，二者的差异在于此光源模块10b更可选择性包含第二发光条220与多个第二固定件320，且类似于第一侧板102，框架100的第二侧板104具有多个第三孔洞(未绘示)。Please refer to FIG. 4 , which is a top view illustrating a light source module according to another embodiment of the present invention. The structure of thelight source module 10b is substantially the same as that of the light source module 10, the difference between the two is that thelight source module 10b can optionally include a secondlight strip 220 and a plurality of second fixingmembers 320, similar to the first side Theboard 102 and thesecond side board 104 of the frame 100 have a plurality of third holes (not shown).

在光源模块10b中，第二发光条220设置于第二侧板104上。在一实施例中，此第二发光条220包含第二电路板221、多个第二点光源222与相对应第三孔洞的多个第四孔洞(未绘示)。每一个第二点光源222是设置在第二电路板221上，且电性连接第二电路板221。第二点光源222的发光面220a是朝向第二入光面402。每一个第二点光源222具有第三厚度222a，且每一个第二点光源222与导光板400间具有第二距离402a。类似于第一电路板211，这些第四孔洞则穿设于第二电路板221中。在一例子中，这些第二点光源222是发光二极管、激光二极管、或上述点光源的组合。In thelight source module 10b, the secondlight strip 220 is disposed on thesecond side panel 104 . In one embodiment, the secondlight strip 220 includes asecond circuit board 221 , a plurality of second pointlight sources 222 and a plurality of fourth holes (not shown) corresponding to the third holes. Each second pointlight source 222 is disposed on thesecond circuit board 221 and electrically connected to thesecond circuit board 221 . The light-emittingsurface 220 a of the second pointlight source 222 faces the second light-incident surface 402 . Each second pointlight source 222 has athird thickness 222a, and there is asecond distance 402a between each second pointlight source 222 and thelight guide plate 400 . Similar to thefirst circuit board 211 , the fourth holes are formed in thesecond circuit board 221 . In one example, the second pointlight sources 222 are light emitting diodes, laser diodes, or a combination of the above point light sources.

第二固定件320是设置于导光板400与第二发光条220间。每一个第二固定件320包含第二接合部(未绘示)与第二固定部324，且第二固定部324是接合于第二接合部。第二接合部是分别对应穿透第四孔洞，且分别对应嵌合于第二侧板104的第三孔洞的一者中。如此，通过第二固定件320，可将第二发光条220固定于框架100的第二侧板104上。在一例子中，第二接合部与第三孔洞的嵌合可以螺合、紧配合、卡固、或上述方法的组合来达成。Thesecond fixing member 320 is disposed between thelight guide plate 400 and the secondlight strip 220 . Each second fixingpart 320 includes a second joint part (not shown) and asecond fixing part 324 , and thesecond fixing part 324 is joined to the second joint part. The second joint portions respectively pass through the fourth holes and are correspondingly fitted into one of the third holes of thesecond side plate 104 . In this way, the secondlight strip 220 can be fixed on thesecond side panel 104 of the frame 100 through the second fixingmember 320 . In one example, the fitting of the second engaging portion and the third hole can be achieved by screwing, tight fitting, clamping, or a combination of the above methods.

第二固定部324设置于第二发光条220与导光板400间。第二固定部324具有第四厚度324a。在一例子中，第四厚度324a是大于第二点光源222的第三厚度222a，通过第二固定部324的支撑，可避免导光板400碰撞第二点光源222。在另一例子中，第四厚度324a是等于第三厚度222a加上述的第二距离402a。Thesecond fixing portion 324 is disposed between the secondlight bar 220 and thelight guide plate 400 . Thesecond fixing part 324 has afourth thickness 324a. In one example, thefourth thickness 324 a is greater than thethird thickness 222 a of the second pointlight source 222 , and the support of thesecond fixing portion 324 can prevent thelight guide plate 400 from colliding with the second pointlight source 222 . In another example, thefourth thickness 324a is equal to thethird thickness 222a plus the aforementionedsecond distance 402a.

由于第二点光源222与导光板400间具有第二距离402a。因此，第二点光源222与导光板400间有空气的阻隔。通过空气的阻隔，可降低导光板400接受的热能，避免导光板400因热熔融变形，更可兼顾光源模块10b的光学效能。Since there is asecond distance 402 a between the second pointlight source 222 and thelight guide plate 400 . Therefore, there is an air barrier between the second pointlight source 222 and thelight guide plate 400 . Through the barrier of the air, the heat energy received by thelight guide plate 400 can be reduced, the deformation of thelight guide plate 400 due to heat melting can be avoided, and the optical performance of thelight source module 10 b can be taken into consideration.

而第二距离402a是随着第二点光源222的功率大小与导光板400的材质不同，而有所变动。当第二距离402a过小时，导光板400易因第二点光源222所发出的热，造成导光板400熔融变形。当第二距离402a小于0时，导光板400会碰撞到这些第二点光源222，造成第二发光条220损坏。而当第二距离402a过大时，导光板400的导光效果不佳，使光源模块10b的效能降低。Thesecond distance 402 a varies with the power of the second pointlight source 222 and the material of thelight guide plate 400 . When thesecond distance 402 a is too small, thelight guide plate 400 is easily melted and deformed by the heat generated by the second pointlight source 222 . When thesecond distance 402 a is less than 0, thelight guide plate 400 will collide with the second pointlight sources 222 , causing damage to the secondlight strip 220 . However, when thesecond distance 402a is too large, the light guiding effect of thelight guide plate 400 is not good, which reduces the efficiency of thelight source module 10b.

因此，在本实施方式中，通过第二固定件320的第二固定部324的固定支撑，可固定第二距离402a的大小，使得导光板400具有良好的导光效果，亦不因第二点光源222发出的热，产生熔融变形。Therefore, in this embodiment, through the fixed support of thesecond fixing part 324 of the second fixingmember 320, the size of thesecond distance 402a can be fixed, so that thelight guide plate 400 has a good light guiding effect, and it is not caused by the second point. The heat emitted from thelight source 222 produces melting deformation.

此外，通过第二固定部324的支撑，可避免导光板400因重力或晃动影响，碰撞第二点光源222，造成第二发光条220破损。而且，通过第二固定部324的固定，可避免导光板400晃动，且可固定第二距离402a的大小。In addition, through the support of thesecond fixing portion 324 , thelight guide plate 400 can be prevented from colliding with the second pointlight source 222 due to gravity or shaking, causing damage to the secondlight emitting strip 220 . Moreover, through the fixing of thesecond fixing part 324 , the shaking of thelight guide plate 400 can be avoided, and the size of thesecond distance 402a can be fixed.

相同地，在一例子中，第二固定件320可为高分子材料、金属材料、或上述材料的组合。在另一例子中，第二固定件320亦可选用可透光或半透光的材质，以避免因第二固定件320的设置，而造成第二点光源222所发出的光受到干扰，导致光源模块10b形成暗区。Similarly, in an example, the second fixingmember 320 can be a polymer material, a metal material, or a combination of the above materials. In another example, the second fixingmember 320 can also be made of light-transmissive or semi-transparent material, so as to avoid the interference of the light emitted by the second pointlight source 222 due to the setting of the second fixingmember 320, resulting in Thelight source module 10b forms a dark area.

在一例子中，第二接合部与第二固定部324是一体成型的结构。在另一例子中，第二接合部与第二固定部324可不为一体成型的结构，借以增加第二固定件320对于各种光源模块的通用性。例如：第二接合部先将第二发光条220嵌合于第四孔洞中，再依光源模块的需求选用适当的第二固定部324，再将第二固定部324与第二接合部两者作结合。In one example, the second engaging portion and thesecond fixing portion 324 are integrally formed. In another example, the second joint part and thesecond fixing part 324 may not be integrally formed, so as to increase the versatility of thesecond fixing part 320 for various light source modules. For example: the second joint portion first fits the secondlight bar 220 into the fourth hole, and then selects an appropriatesecond fixing portion 324 according to the requirements of the light source module, and then connects thesecond fixing portion 324 and the second joint portion for combination.

在一例子中，第二接合部与第二固定部324可为同样的材料所组成，亦可为相异的材料所组成。在另一例子中，第二固定部324可为两种或两种以上的材料所组成。例如：第二固定部324可为一双层材料结构，内层为金属材质，外层为高分子材料。内层的金属材质可耐受第二点光源222所发出的热。外层的高分子材料则具有耐冲击的特性，可避免导光板400因碰撞造成破损。In one example, the second joint portion and thesecond fixing portion 324 can be made of the same material, or can be made of different materials. In another example, thesecond fixing portion 324 may be composed of two or more materials. For example, thesecond fixing part 324 can be a double-layer material structure, the inner layer is made of metal material, and the outer layer is made of polymer material. The metal material of the inner layer can withstand the heat emitted by the second pointlight source 222 . The polymer material of the outer layer has impact resistance, which can prevent thelight guide plate 400 from being damaged due to collision.

在一例子中，这些光源模块10、10a与10b皆可再与反射板、增亮膜及扩散片等光学薄膜结合，以形成一背光模块，应用于液晶显示器中。In one example, theselight source modules 10 , 10 a and 10 b can be combined with optical films such as reflectors, brightness enhancement films, and diffusers to form a backlight module for use in liquid crystal displays.

由本实用新型上述实施例可知，本实用新型的光源模块的优点在于将提供导光板支撑力的组件与固定发光条的组件相结合，使导光板不需要额外的结构设计即可达到固定的目的，借以简化制程，提高导光板对于各种光源模块的通用性。这些固定件亦可满足显示器窄边框的需求，改善已知技术应用于窄边框时，固定件外露的缺陷。对于大尺寸面板，本实用新型亦可提供充足的支撑力，避免导光板碰撞点光源。此外，本实用新型亦不影响点光源的光学效能，不会造成光源模块效能降低。确实改善已知制程中导光板的限制与缺陷。It can be known from the above-mentioned embodiments of the utility model that the light source module of the utility model has the advantage of combining the component providing the support force of the light guide plate with the component fixing the light strip, so that the light guide plate can be fixed without additional structural design.
