Description

LED日光灯
技术领域
本发明涉及一种灯具， 属于照明装置领域。
背景技术
LED灯作为新一代的照明装置， 具有高节能、 绿色环保、 无紫外光辐射、 寿 命长等优点。 LED T8/T10日光灯采用发光二极管作为光源， 在发光原理、 节能、 环保的层面上都远远优于传统的荧光灯。 但是， LED T8/T10 日光灯内设置的发 光二极管数量较多，发热量大，更加依赖于良好的散热结构，而良好的散热结构， 又被灯具本身的尺寸所局限。 这就对 LED円光灯在结构、 散热、 光学、 电子驱动 方面的设计提出了更高的要求。
中国专利文献 CN102072428中公开了一种 LED日光灯，包括基座和固定于基 座上的灯罩和光源基板，光源基板上安装有多个发光二极管；灯罩包括第一表面， 第二表面以及入光端部，该入光端部正对发光二极管出光方向设置，入光端部包 括入光端面和反射部，发光二极管发出的光线从入光端面进入灯罩,经反射部反 射后在灯罩内部传输，直至从第一表面和第二表面射出。 该结构使得 LED日光灯 的光照射角增大，均匀度增加。但是该 LED日光灯的基座和灯罩采用分体式设计， 材质不同， 组装繁琐， 加工成本高。
中国专利文献 CN201964217中公开了一种 LED日光灯，包括光源灯罩和散热 体插接组成的灯身，安装于灯身内的 LED电路板, LED电路板上安装有 LED光源， 固定于灯身一端与 LED光源电连接的驱动电源组件,驱动电源组件包括电源盒体 及置于电源盒体内的驱动电源；电源盒体包括面盖和底座，底座固定于灯身一端， 驱动电源固定于面盖内与面盖共同卡接于底座上。该 LED H光灯的灯罩和散热体 相互插接组成灯身， 同样存在组装繁琐， 加工成本高的问题。另外电源盒体位于 灯身之外， 外形不够美观； 且电源盒体的面盖和底座卡接在一起， 拆装灯管时， 很容易造成电源盒体的面盖和底座分离， 造成不必要的麻烦。
发明内容
本发明要解决的技术问题是， 提出一种结构紧凑， 组装拆卸安全便捷， 照明 效果好， 散热效果好的 LED日光灯。
本发明为解决上述技术问题提出的技术方案是：一种 LED日光灯，包括灯管、 设于所述灯管内的基板和位于所述灯管两端的灯头， 所述基板上设有 LED灯珠， 所述灯头内安装电源器件且外端延伸出接线端子，所述灯管由导热基座部和所述 导热基座部宽度方向两侧延伸出的连体弧形透光罩体部构成，所述导热基座部的 两端分别具有卡孔，所述基板紧贴于所述导热基座部的内表面上； 所述灯头的外 端上部朝内延伸出具有底部条状缺口的圆管，所述灯头的外端下部延伸出位于所 述条状缺口处的弹性舌片； 所述圆管和弹性舌片的包络外廓与灯管的内廓相配； 所述弹性舌片的端部具有与所述卡孔相配的卡扣；所述灯管内具有隔离 LED灯珠 和电源器件的隔板， 所述隔板的包络外廓与灯管的内廓相配； 组装时， 所述隔板 夹持在所述灯头内端与基板端头之间， 所述卡扣卡入所述卡孔内定位。
为了使得 LED日光灯的结构更加紧凑，外形更加美观， 一种优选的技术方案 是： 上述灯头插入灯管内的长度超过所述灯头全长的一半。
为了更好地进行散热， 同时更便于基板的安装， 一种优选的技术方案是： 上 述导热基座部内表面具有形成长度方向插槽的相对卡钩，所述基板插装固定在所 述插槽内； 组装时， 所述卡钩位于所述条状缺口处。
为了使得隔板能保证 LED 灯珠发出的光线不会进入灯头内， 且安装更加便 捷， 一种优选的技术方案是： 上述隔板上设有与所述卡钩相对应的第一缺口和用 于穿过导线的第二缺口。
为了使得隔板的固定效果更好， 且安装更加便捷， 一种优选的技术方案是： 所述圆管的管壁两侧设有向内伸出的卡接头；所述隔板的两侧边缘处设有与所述 卡接头对应卡接的卡接口。
为了使得电源器件的组装、拆卸更加方便， 一种优选的技术方案是： 上述圆 管的内壁上设有沿所述圆管的轴向对称设置的卡槽；所述电源器件的电路板设于 所述卡槽内， 且夹持于所述隔板和所述灯头的外端端面之间。
为了使得灯头与灯管的组装、拆卸定位准确且更加方便，一种优选的技术方 案是： 上述圆管的外壁上设有压紧所述灯管的挡圈。

本发明的 LED 日光灯的灯管为整体注塑而成， 分为导热基座部和透光罩体 部， 透光罩体部的面积较大， 透光效果好； 由于基板的热量直接通过导热基座部 散去， 省掉了金属散热器， 在保证散热效果的前提下， 有效地降低了成本。 全部 采用塑料材质还使得该 LED日光灯更加安全可靠。该 LED日光灯在组装时电源器 件先设于独立的灯头中， 然后灯头再插入灯管内固定， 拆装方便， 外形美观。 夹 持在灯头内端与基板端头之间的隔板可以有效地阻止 LED 灯珠发出的光线进入 灯头， 同时便于电源器件的拆装。 该 LED R光灯通过对灯管结构、 灯头结构、 电 源组件位置等的优化设计，使得该 LED日光灯结构紧凑，质量轻便，照明效果好， 散热效果好， 灯头更换方便， '使用寿命长。
