请参照图1 ,习知侧向发光型的发光模块100包括一发光二极管(Light Emitting Diodes, LED)芯片(chip)l 10与一透镜]20, 其中透镜120具有一光入射面122、一全反射面124以及一侧边出光面126。 Referring to FIG. 1, a conventional side-emission type light emitting module 100 comprises an LED (Light Emitting Diodes, LED) chip (chip) l 10 and a lens] 20, wherein the lens 120 has a light incident surface 122, a whole a reflective surface 124 and the side surface 126. 由图1可知,透镜120的全反射面124位于光入射面122上方,而透镜120的光入射面122邻近发光二极管芯片110, 且侧边出光面126连接全反射面124以及光入射面122。 Figure 1 shows, total reflection surface 120 of the lens 124 is located above the light incident surface 122, and the light incident surface 122 adjacent the lens 120, the light emitting diode chip 110, and the side surface 126 connecting the total reflection surface 124 and a light incident surface 122.

在上述的发光模块100中,发光二极管芯片110适于提供一光线112,且光线112会从光入射面122进入透镜120。 In the light-emitting module 100, the light emitting diode chip 110 is adapted to provide a light 112, light 112 and enters the lens 120 from the light incident surface 122. 由图l可知,透镜120的全反射面124具有特殊的曲率设计,以反射发光二极管芯片110所提供的光线112。 L is apparent from FIG, total reflection surface 120 of the lens 124 has a special curvature design, the light reflected to the light emitting diode chip 110 is provided 112. 理想状态下,进入透镜120 的部分光线112会被全反射面124反射,并从侧边出光面126出射;进入透镜120的其余光线112则不会被全反射面124反射而直接从侧边出光面126出射。 Ideally, the light entry portion 112,120 will be totally reflecting surface of the lens 124, and from the side of the exit surface 126; 112 to enter the rest of the light is not reflected by the total reflection surface 124 of the lens 120 and the light directly from the side an exit surface 126. 此外,由于透镜120的侧边出光面126具有特殊的曲率设计,因此,光线112从透镜120出射后的光路径方向大致上垂直于中心轴50,以达到侧向出光的目的。 Further, since the side surface 126 of the lens 120 has a special curvature design, therefore, the optical path of the light from a direction substantially 112 after exiting the lens 120 perpendicular to the central axis 50, to achieve the purpose of lateral light.

然而,由于透镜120在实际制作时容易因为制程的疏失(如射出模具的制作误差、磨耗、透镜被刮伤等),而在透镜120的 However, since the lens 120 is easy to process because of negligence (e.g., manufacturing errors emitted mold wear, the lens was scratched and the like) in the actual production, and the lens 120

FIG. 5. 【具体实施方式】 第一实施例 DETAILED DESCRIPTION [First embodiment]

请参考图2,本发明第一实施例的发光模块200具有一中心轴Cl,且发光模块200包括一光源210、-一透镜220以及一遮光层230。 Referring to FIG 2, a first embodiment of a light emitting module according to the present invention having a central axis 200 of Cl, and the light emitting module 200 includes a light source 210, - a lens 220 and a light shielding layer 230. 由图2可知,光源210适于提供光线212,而透镜220配置于光源210的上方,其中透镜220具有光入射面222、全反射面224以及侧边出光面226。 It is seen from FIG. 2, the light source 210 is adapted to provide light 212, and the lens 220 is disposed above the light source 210, a lens 220 which has a light incident surface 222, a total internal reflection surface 224 and side surface 226. 光入射面222位于光源210的上方,而全反射面224位于光入射面222的上方,侧边出光面226连接光入射面222以及全反射面224。 The light incident surface 222 is positioned above the light source 210, and the total reflection surface located on the light incident surface 222 of the top 224, a side surface 226 connecting the light incident surface 222 and the total reflection surface 224. 光线212适于从光入射面222进入透镜220中,而全反射面224适于反射进入透镜220中的光线212 , 并使光线212从透镜220的侧边出光面226射出。 Ray 212 from the light incident surface 222 is adapted to enter the lens 220, total reflection surface 224 adapted to reflect light rays entering the lens 220 in 212, 212 and the light emitted from the side surface 226 of the lens 220. 其中,遮光层230配置于至少部分的全反射面224上,配置的区域为全反射面224上的漏光区。 Wherein the light shielding layer 230 disposed on at least a portion of the total-reflection surface 224, the light leakage region is a region arranged on the total reflection surface 224. 由于透镜220在实际制作时容易因为制程的疏失(如射出模具的制作误差、磨耗、透镜被刮伤等),而在透镜220 的全反射面224上形成漏光区, 一般常见的漏光区是位在透镜220 的脱膜角处,如图2中V型全反射面224的底部。 Since the lens 220 in the actual production process is easy because of negligence (e.g., injection mold manufacturing error, abrasion, scratches and the like lens), the light leakage region is formed on the total reflection surface 220 of the lens 224, the light leakage region is a general common location in the release angle of the lens 220, V-2, the bottom total reflection surface 224 of FIG.

承上述,光源2 10为一发光二极管芯片,且此发光二极管芯片具有一发光主轴C2。 Bearing the above, the light source 210 is a light emitting diode chip, and the light-emitting diode chip having a light emitting main shaft C2. 在本实施例中,发光主轴C2例如是与发光模块200的中心轴Cl重合。 In the present embodiment, for example, a light emitting spindle C2 coincide with the center axis of the light emitting module 200 Cl. 此外,配置于全反射面224」:的遮光层230,其配置位置对应于光源210,如图2所示,遮光层23() 系位干光源210的正上方,且遮光层230配置于全反射面224上的漏光区,其所涵盖的面积可略大于、等于或是略小于光源210 的发光面积。 Furthermore, total reflection surface 224 arranged ": the light-shielding layer 230, which is disposed in a position corresponding to light source 210, shown in Figure 2, the light shielding layer 23 () dry bit lines directly above the light source 210, and the light shielding layer 230 is disposed on the whole leakage region on the reflecting surface 224, it covers an area slightly larger than, equal to or slightly smaller than the emitting area of ​​the light source 210. 在本实施例中,遮光层230是会反射光线的光反射层,其可以是利用涂布(蒸镀或溅镀)的方法形成于全反射面224 上,具体而言,遮光层230的材质包括金属如银、铝、铬、高分子膜,或是可以反射光线的遮光材料。 In the present embodiment, the light shielding layer 230 is a light reflective layer may reflect light, which may be applied using a (evaporation or sputtering) process is formed on the total reflection surface 224, specifically, the material of the light shielding layer 230 It includes metals such as silver, aluminum, chromium, a polymer film, or may reflect the light shielding material.

当光源210发亮提供光线21.2时',光源210所提供的光线212 会从光入射面222进入透镜220,进入透镜220的部分光线212 会传递至全反射面224,并且被全反射面224反射后从侧边出光面226出射,而进入透镜220的其余光线212则不会被全反射面224 反射而直接从侧边出光面226出射。 21.2 When the light source 210 providing light lit ', the light source 210 enters 212 provided from the light incident surface 222 of the lens 220, the lens 220 into the portion of the light 212 is passed to the total reflection surface 224, and is reflected by the total reflection surface 224 after the exit from the side surface 226, light rays enter the lens 220 of the remaining 212 will not be reflected by the total reflection surface 224 exit surface 226 directly from the side. 由于透镜220的光入射面222 、 全反射面224以及侧边出光面226皆具有特殊的曲率设计,因此这些从侧边出光面226出射的光线212的光路径大致上会垂直于发光模块200的中心轴Cl。 Since the light incident surface 222 of the lens 220, total reflection surface 224 and side surface 226 both have a special curvature design, and therefore these light exit surface 226 from the side of the optical path of the light emitted is substantially 212 will be perpendicular to the light emitting module 200 the center axis Cl. 本实施例在透镜220的部分全反射面224上制作遮光层230,而此遮光层230除了避免光线212直接从全反射面224射出,还可加强全反射面224反射部分光线212的效果,进而增进发光模块200侧向发光的效果。 Prepared according to the present embodiment the light shielding layer 230 on a portion of the total-reflection surface 224 of the lens 220, and this light shielding layer 230 in addition to avoiding the light 212 emitted from the total reflection surface 224, 224 may further strengthen the effect of the light reflecting portion 212 of the total reflection surface, and further enhance the light emitting module 200 light emitting side effects.

此外,为了保护遮光层230,可以在遮光层230上配置一保护层240,而此保护层240的材质例如是硅胶(Silicone)或是环氧树脂(Epoxy)。 Further, in order to protect the light-shielding layer 230, a protective layer 240 may be disposed on the light shielding layer 230, and this material of the protective layer 240 is, for example, silicone (Silicone) or epoxy resin (Epoxy). 因此,在将发光模块200组装至其它装置的组 Thus, the light emitting module 200 is assembled to another device group

装过程中,保护层240可以保护遮光层230,避免遮光层230因与其它组件接触而受到破坏。 Installation process, the protective layer 240 may protect the light-shielding layer 230, the light shielding layer 230 by avoiding contact with the other components and damaged. 或者,本实施例亦可在遮光层230以及保护层240之间形成--层高分子膜,以加强全反射面224的反射效果。 Alternatively, the present embodiment may also be formed between the light shielding layer 230 and the protective layer 240 Polymer - membrane layer to enhance the total reflection surface 224 of the reflection effect.

综上所述,由于透镜220容易因为制程的疏失(如射出模具的制作误差、磨耗、透镜被刮伤等)而在全反射面224上形成漏光区,而漏光区会使发光模块200的侧向出光效果变差。 As described above, since the lens 220 is easy because of negligence process (e.g., injection mold manufacturing error, abrasion, scratches and the like lens) are formed on the total reflection surface leakage region 224, and side-leakage region 200 causes the light emitting module the deterioration of the light effect. 所以, 本实施例在全反射面224上制作遮光层230,以避免光线212从全反射面224射出,进而使光线212都是从透镜220的侧边出光面226射出。 Therefore, the present embodiment, the total reflection surface 224 formed on the light-shielding layer 230, 212 in order to prevent light emitted from the total reflection surface 224, the light rays 212 are further out from the side surface 226 of the lens 220 is emitted. 与习知相较,本发明的发光模块200具有更佳的侧向出光效果。 Compared with the conventional light emitting module 200 according to the present invention have a better side effect of light. 第二实施例 Second embodiment

请参考图3,本发明第二实施例的发光模块与第一实施例的发光模块相似,二者主要不同的处在于:本实施例的发光模块200' 中的遮光层230,包括一中心遮光层232以及一外部遮光层234。 Please refer to FIG. 3, a second embodiment of light emitting modules according to the present invention is similar to the first embodiment, both the main difference is that: a light emitting module according to the light shielding layer 200 'of the present embodiment 230, comprising a central light-shielding an outer layer 232 and the light shielding layer 234.

如图3所示,本实施例的遮光层23(T的中心遮光层232是位于光源210上方的全反射面224上,而外部遮光层234也是位于全反射面224上,但外部遮光层234环绕中心遮光层232。其中, 中心遮光层232系设置于透镜220因制程疏失于全反射面224上形成的漏光区。外部遮光层234设置于全反射面224上的区域系针对封装发光二极管或组装发光模块时所造成的漏光区,此漏光区是因为封装或组装底座的机械轴与发光模块的光轴不容易重合一致,多少有位移(shift)现象而造成的。 3, the light-shielding layer according to the present embodiment is 23 (T is the center of the light shielding layer 232 is located above the light source 210 and the total reflection surface 224, and the external light shielding layer 234 is positioned on the total reflection surface 224, the external light shielding layer 234 wherein surrounding the central light shielding layer 232. the center line 232 is provided on the light-shielding layer 220 leakage region due to negligence routing total reflection surface 224 is formed on the lens. region based on the external light shielding layer 234 is disposed on the total reflection surface 224 of the package for a light emitting diode or when the light emitting module assembly caused by leakage region, this is because the optical axis of the light leakage zone of the base assembly of the package or the mechanical axis of the light emitting module does not easily overlap consistent with a displacement number (Shift) caused by the phenomenon.

当一部分的光线212传递至全反射面224时,遮光层230'的 When a portion of light 224 is transmitted to the total reflection surface 212, the light-shielding layer 230 '

中心遮光层232以及外部遮光层234可以避免光线212从全反射面224的特定区域(漏光区)射出,同时加强全反射面224反射光线212的效果。 The central light shielding layer 232 and an outer shielding layer 234 to avoid light 212 emitted from a specific area (light leakage area) of the total reflection surface 224, while enhancing the effect of the total reflection surface 224 of reflected light 212. 因此,发光模块200,可以具有较良好的侧向出光效果。 Thus, the light emitting module 200, may have a relatively good lateral light effect. 承上述,中心遮光层232与外部遮光层234涵盖于全反射面224上的面积大小及形状,以及外部遮光层234的配置数量, 都可以依照实际制程以及设计需求加以调整。 Bearing the above, the center of the external light shielding layer 232 covers the light shielding layer 234 on the surface 224 of the total reflection area size and shape, and the number of the external light shielding layer 234 is disposed, can be adjusted according to actual process and design requirements. 第三实施例 Third Example

请参考图4,本发明第三实施例的发光模块与第一及第二实施例的发光模块相似,但不同的处在于:本实施例的发光模块200" 中的遮光层230",完全覆盖住全反射面224。 Please refer to FIG. 4, the light emitting module of the third embodiment of the present invention, the light emitting module and the first and second embodiment is similar, but different in that: the light emitting module 200 according to the present embodiment, "the light-shielding layer 230 'completely cover live total reflection surface 224.

如图4所示,由于本实施例的遮光层230"完全覆盖住全反射面224,因此全反射面224上不会有漏光区。此外,遮光层230" 的材质为金属或是可以反射光线的遮光材料,因此完全覆盖住全反射面224的遮光层230"可以增加全反射面224反射光线212的效果。当部分的光线212传递至全反射面224时人全反射面224 会反射所有传递至全反射面224的部分光线212,使光线212无法从全反射面224的特定区域射出。光线212被全反射面224反射后,会从侧边出光面226射出。相较于习知,光线212在进入透镜220的后,皆是从侧边出光面226射出,因此本实施例的发光模块200"具有良好的侧向出光效果。 4, since the light-shielding layer 230 according to the present embodiment is "completely covered the total reflection surface 224, so there is no total reflection surface leakage region 224. Further, the light shielding layer 230 'made of metal or reflect light the light-shielding material, thus completely covering the total reflection surface of the light-shielding layer 224 230 '224 can increase the effect of total reflection surface 212 reflecting light. when the light transmitting portion 212 to the total reflection surface 224 people totally reflective surface 224 will transfer all to the total reflection surface 224 of the portion of light 212, 212 so that light can not be emitted from the total reflection surface 224 of the specific region. after the light 212 is totally reflecting surfaces 224, 226 will be emitted out from the side surface. compared to conventional light 212 after entering the lens 220, the light exit surface are both emitted from the side 226, the light-emitting module of the present embodiment 200 'has good lateral light effect. 另外,完全覆盖住全反射面224的遮光层230",于实际制作上较为方便。 第四实施例 Further, the total reflection surface completely covering the light-shielding layer 230 224 ", in the actual production is more convenient to the fourth embodiment

请参考图5,本发明第四实施例与第二实施例相似,但不同的处在于:本实施例的发光模块300中的遮光层330'为会吸收光线的光吸收层。 Please refer to FIG. 5, a fourth embodiment of the second embodiment of the present invention is similar to, but different in that: the light-shielding layer light emitting module 300 according to the present embodiment 330 'of the light absorbing layer absorbs light.

如图5所示,遮光层330'配置于全反射面224上。 5, the light shielding layer 330 'disposed on the surface 224 is totally reflected. 在本实施例中,遮光层330'包括中心光吸收层332以及外部光吸收层334, 其中中心光吸收层332的位置对应于光源210,且中心光吸收层332所涵盖的面积可略大于、等于或是略小于光源210的发光面积。 In the present embodiment, the light shielding layer 330 'includes a center of the light absorbing layer 332 and the external light absorbing layer 334, wherein the position of the center layer 332 corresponds to the light-absorbing light source 210, and the center of the light absorbing layer 332 may be slightly larger than the area covered, is equal to or slightly smaller than the emitting area of ​​the light source 210. 外部光吸收层334则是环绕光吸收层332。 The external light absorbing layer 334 is surrounded by the light-absorbing layer 332. 由于光吸收层332 及334会吸收光线,所以原本从全反射面224的漏光区出射的光线212会被中心光吸收层3 3 2及外部光吸收层3 3 4吸收。 Since the light absorbing layer 332 and 334 may absorb light, so that light leakage from the original area of ​​the total reflection surface 224 emitted light 212 will be the center of the light-absorbing layer 332 and the external light absorbing layer 334 to absorb. 相较于习知,在本实施例的发光模块300中,光线212都是从侧边出光面226出射,不会有光线212从全反射面224射出透镜的外,因此本实施例的发光模块300具有良好的侧向出光效果。 Compared to conventional, in the light emitting module 300 according to the present embodiment, the light rays 212 are emitted from the side surface 226, no light is emitted from the lens 212 224 is totally reflected from the outer surface, the light-emitting module of the present embodiment 300 has good lateral light effect.

承上述,虽然本实施例的发光模块300的遮光层330'包括中心光吸收层332及外部光吸收层334,但中心光吸收层332与外部光吸收层334的配置可视透镜220的需求个别单独设置或共同设置。 Bearing the above, although the present embodiment, the light emitting module 300 light-shielding layer 330 'includes a center of the light absorbing layer 332 and the external light absorbing layer 334, but the center of the light-absorbing layer 332 and the external light absorbing layer 334 disposed 220 individual visual needs of the lens set individually or jointly setting. 也就是说,本发明并不限定发光模块300内的光吸收层的数量及其配置位置,但光吸收层须配置在全反射面224上的漏光区, 以避免光线212从全反射面224出射。 That is, the present invention is not limited to the number and position of the light absorbing layer disposed in the light emitting module 300, but the light-absorbing layer to be disposed on the light leakage region 224 total reflection surface, in order to prevent light emitted from the 212,224 total reflection surface .

综上所述,本发明的发光模块是在全反射面上配置遮光层, 以使发光模块具有良好的侧向出光效果。 In summary, the present invention is a light-emitting module disposed on the total reflection surface of the light-shielding layer, so that the light emitting module having a good lateral light effect. 当遮光层为光反射层时, 遮光层可以帮助全反射面反射所有传递至全反射面的光线,使所有传递至透镜内的光线皆是由侧边出光面射出。 When the light-shielding layer is a light-reflecting layer, a light-shielding layer may assist the total reflection surface of the reflection light is transmitted to all of the total reflection surface, so that all the light transmitted to the inner lenses are emitted by the light emitting surface side. 因此,光线不会从直接从全反射面射出于透镜的外,故发光模块具有良好的侧向出光效果。 Thus, the light emitted from the lens is not totally reflected from the outer surface, so that the light emitting module having a good lateral light effect. 透过于全反射面上配置遮光层,使本发明的发光模块可容许更高的透镜制造误差、封装发光二极管或组装发光模块的 Through the total reflection surface of the light shielding layer, the light emitting module of the present invention may allow a higher lens manufacturing error, assembly package or a light emitting diode emitting module

组装误差。 Assembling error.

此外,当遮光层为光吸收层时,光吸收层会吸收从全反射面的漏光区出財的光线,使光线不会从全反射面射出于透镜之外。 Further, when the light-shielding layer is a light-absorbing layer, the light absorbing layer absorbs light from the light leakage zone fiscal the total reflection surface, so that the light is not totally reflected is emitted outside from the surface of the lens. 因此,光线都是从透镜的侧边出光面射出,故发光模块具有良好的侧向出光效果。 Thus, the light rays are emitted from the side surface of the lens, so that a lateral light-emitting module having excellent light effect.

虽然本发明已以一实施例揭露勿I上,然其并非用以限定本发 Although the embodiments of the present invention is disclosed in a not to the I, however not intended to limit the invention
