Description

LED日光管的改进结构
技术领域
本实用新型涉及一种日光灯，更具体的说，涉及一种LED日光管的改进结构。
背景技术
现有技术的LED日光管，由于其结构设计不合理，在出光面的PC罩采用扩光罩的条件下，灯管正常发光时，由于LED发光点之间的点距，能明显的存在灯管暗斑，现有技术的LED外置电源日光管，容易给人亮度不均的感觉，而使用者很在意这点，他们希望LED灯具制造厂家能提供一种能达到传统荧光灯管发光效果的LED日光管。现有技术中，LED日光管存在出现暗斑的技术缺陷，成为本领域技术人员急待解决的技术问题。
发明内容
本实用新型的技术目的是克服现有技术中LED日光管发光时存在暗斑的技术问题，提供一种光线柔和均匀的LED日光管的改进结构。
为实现以上技术目的，本实用新型的技术方案是
LED日光管的改进结构，包括有LED发光二极管，其特征是：所述日光管设有弧形铝壳，在所述弧形铝壳的上方，设有PCB板，所述PCB板上设有LED发光二极管，PCB板连接电源；在所述弧形铝壳的下方设有扩光罩。
更进一步的，所述PCB板与弧形铝壳之间设有导热硅胶固定层。
更进一步的，所述扩光罩是PC扩光罩。
在本实用新型的设计中，改变了现有技术中将PCB板设置于卡槽的结构，将PCB板设置于弧形铝壳上方，增加发光点到PC扩光罩的距离，让相邻两个LED发光二极管发出的光线在到达PC扩光罩时亮度比较均匀，进而消除由于LED发光二极管与PC扩光罩之间的距离太小而出现的暗斑，令LED日光管呈现传统荧光灯管的发光效果。
本实用新型的有益技术效果是：消除了现有技术中LED日光灯管的暗斑，发光柔和均匀并且导热及散热性能好；本实用新型结构简单、成本低廉且易于实施。
附图说明
图1是本实用新型一个实施例的截面结构示意图。
具体实施方式
结合图1，详细说明本实用新型的具体实施方式，但不对权利要求作任何限定。
本实用新型LED日光管的改进结构中包括有LED发光二极管102，日光管设有弧形铝壳100，在所述弧形铝壳100的上方，设有PCB板101，PCB板101与弧形铝壳100之间设有导热硅胶固定层103，进行导热并固定。PCB板101上设有LED发光二极管102，PCB板101连接电源；在弧形铝壳100的下方设有扩光罩104。扩光罩104采用PC材料制作。在本实用新型的设计中，改变了现有技术中将PCB板101设置于卡槽105的结构，将PCB板101设置于弧形铝壳100上方，增加发光二极管102到扩光罩104的距离，让相邻两个LED发光二极管102发出的光线在到达扩光罩104时亮度比较均匀，进而消除由于LED发光二极管102与PC扩光罩之间的距离太小而出现的暗斑，令LED日光管呈现传统荧光灯管的发光效果。
本实用新型选择扩光效果好的PC罩和散热性能好的铝壳，把LED发光二极管呈线性排列的PCB板用粘接性极强的导热硅胶粘到铝管的弓形顶部，增加了开LED发光二极管与PC扩光罩的距离，让相邻两个LED发光二极管的光线充分混合，光线到达PC罩前暗区已被相邻LED发光二极管的光线给填充，光线透过PC扩光罩后发光面就很均匀柔和，呈现传统荧光灯管的发光效果。
本实用新型消除了现有技术中LED日光灯管的暗斑，发光柔和均匀并且导热及散热性能好；是本领域一个既实用又新型的技术改进。
