Description

一种侧光式的LED集成灯管
技术领域
本发明涉及一种LED集成灯管，具体涉及一种侧光式的LED集成灯管。
背景技术
发光二极管凭借其优异的性能正逐步走向家居和商业照明，应用非常广泛。单个发光二极管在照明的应用中，存在亮度小等问题。而LED集成灯管则能够克服亮度不足的问题，因此LED集成灯管也越来越受到大众的欢迎。
现有技术的LED集成灯管包括壳体及LED集成芯片电路块，LED集成芯片电路块由印刷电路板及设于其上的多个发光二极管，LED集成芯片电路块设于壳体内，所述壳体由底座和透明盖组成，LED集成芯片电路块设于底座和透明盖配合形成的空腔内，发光二极管向着透明盖。
此种结构的LED集成灯管，由于其光线直接由透明壳出射，会造成光线较为刺眼，而且多个发光二极管所形成的多束光线会造成不均匀，出现暗影，影响照明效果。
发明内容
针对现有技术的缺点，本发明的目的是提供一种出光均匀、避免出现眩光或暗影的侧光式的LED集成灯管。
为实现上述目的，本发明的技术方案为：一种侧光式的LED集成灯管，包括壳体及设于壳体内的LED集成芯片电路块，该壳体内还设有一能将侧面入射光转换为正面导出均匀光的导光组件，该LED集成芯片电路块位于导光组件侧面，该导光组件的正面作为灯管出光面。经过导光组件转换的侧入射光，能够有效解决光线不均匀的现象，避免出现眩光或暗影现象。
具体地，该导光组件包括透光层、设于透光层一面的增透层及设于透光层另一面的波浪状反射层，该LED集成芯片电路块位于透光层侧面，由LED集成芯片电路块发射的光进入透光层，经波浪状结构层反射后，通过透光层由增透层射出。
该增透层表面具有多个呈周期性排布的凹凸结构，且每个周期凹凸结构的宽度为0.2～4mm之间。该波浪状反射层具有至少一个全反射弧面结构。
为了增强波浪状反射层的反射效果，该波浪状反射层的表面还涂覆有反射膜。
具体地，该壳体呈一矩形框架结构，其包括底部及设于底部上相对的两侧部，底部上的另外两侧为开口，该两侧部及底部形成容纳导光组件的空间，两侧部的内壁对应设有用于容纳LED集成芯片电路块的凹部及与导光组件上的凹位配合固定的梯状结构，上述两侧开口分别用于安装有侧盖及接线端，接线端与LED集成芯片电路块电连接。通过上述结构，LED集成芯片电路块及导光组件能紧凑地设置于壳体内，有效减少成品的体积，提高空间利用率。
该侧部及底部为一体成型的散热结构，该侧部及底部为内外两层结构，其中，内层为导热片，外层为散热片.本方案能充分利用壳体结构，将其本身设计为散热结构，能在快速散发LED集成芯片电路块的热量的同时，减少部件的使用，降低成本而且减小产品体积.
为了增强导光组件的导光效果，避免光线从壳体背面泄露，该导光组件与底部之间还设有一反光板。
具体地，该LED集成芯片电路块包括印刷电路板及设于其上的多个LED芯片，接线端为一通用电插口。由于本方案采用了通用电插口，灯管可与各种灯座配合使用，使用非常方便。可广泛应用于各种灯具，例如台灯、壁灯、吸顶灯、栅栏灯或日常照明灯，尤其适用于台灯。
该壳体或LED集成芯片电路块呈条状形、环形或方形结构。
与现有技术相比，本发明具有如下优势：
本发明通过侧入射光及导光组件，能有效将LED光线均匀射出，避免出现眩光或者暗影等现象，有效提高照明效果。
附图说明
图1为本发明的分解结构示意图；
图2为导光组件的侧面示意图。
具体实施方式
以下结合附图对本发明进行详细的描述。
如图1及图2所示，一种侧光式的LED集成灯管，包括壳体1及设于壳体1内的LED集成芯片电路块2，该壳体1内还设有一能将侧面入射光转换为正面导出均匀光的导光组件3，该LED集成芯片电路块2位于导光组件3侧面，该导光组件3的正面作为灯管出光面。LED集成芯片电路块2发出的光线由导光组件侧面入射，经导光组件3导向后由正面射出，由于光线不是直接出射，能够有效解决光线不均匀的现象，避免出现眩光或暗影现象。
具体地，该导光组件3包括透光层4、设于透光层4一面的增透层5及设于透光层4另一面的波浪状反射层6，该LED集成芯片电路块2位于透光层4侧面，由LED集成芯片电路块2发射的光进入透光层4，经波浪状结构层6反射后，通过透光层4由增透层5射出。
该增透层5表面具有多个呈周期性排布的凹凸结构，且每个周期凹凸结构的宽度为0.2～4mm之间，其优选宽度为0.2～1mm之间。光线经过增透层5时，受呈周期性排布的凹凸结构的折射及衍射作用，光线能均匀能从增透层5表面发射出来。
该波浪状反射层6具有至少一个全反射弧面结构。本实施例中，该全反射弧面结构的数量为一个或三个。光线射向波浪状反射层6时，在其全反射弧面结构的作用下，大量的光线均能够返回至透光层4。
本发明为了增强波浪状反射层6的反射效果，该波浪状反射层6的表面还涂覆有反射膜13。
具体地，该壳体1呈一矩形框架结构，其包括底部7及设于底部7上相对的两侧部8，底部7上的另外两侧为开口，该两侧部8及底部7形成容纳导光组件3的空间，两侧部8的内壁对应设有用于容纳LED集成芯片电路块2的凹部9及与导光组件3上的凹位10配合固定的梯状结构11，上述两侧开口分别用于安装有侧盖15及接线端14，接线端14与LED集成芯片电路块2电连接.通过上述结构，LED集成芯片电路块2及导光组件3能紧凑地设置于壳体1内，有效减少成品的体积，提高空间利用率.安装时，将LED集成芯片电路块2设于侧部8的凹部9，再将导光组件3的凹位10对准侧部8的梯状结构11，并顺着梯状结构11推进壳体1空间内，最好安装上侧盖15及接线端14，完成装配.
上述结构中，侧部8的高度与导光组件3的厚度相当，故安装完后的灯具的出光面与侧部8顶端相平。
该侧部8及底部7为一体成型的散热结构，该侧部8及底部7为内外两层结构，其中，内层为导热片，外层为散热片。本方案能充分利用壳体结构，将其本身设计为散热结构，能在快速散发LED集成芯片电路块2的热量的同时，减少部件的使用，降低成本而且减小产品体积。
为了增强导光组件3的导光效果，避免光线从壳体背面泄露，该导光组件3与底部7之间还设有一反光板12。
具体地，该LED集成芯片电路块2包括印刷电路板21及设于其上的多个LED芯片22，接线端14为一通用电插口。由于本方案采用了通用电插口，灯管可与各种灯座配合使用，使用非常方便。可广泛应用于各种灯具，例如台灯、壁灯、吸顶灯、栅栏灯或日常照明灯，尤其适用于台灯。
该壳体1或LED集成芯片电路块2呈条状形、环形或方形结构，满足各种不同的设计需求。
