Description

灯管
技术领域
本发明涉及一种灯管，特别是一种加入电磁兼容性滤波器的真空灯管。
背景技术
在当前，灯管作为一种照明装置已经被普遍使用。但是，市场上的普遍灯管存在很多不足之处。首先，当灯管外层使用一段时间后，一些不可抗衡的自然现象如空气、温度、湿度、风干等问题会对外层产生不同程度的化学作用。为普遍的是外层的内/外表面积聚尘埃、结露、结雾、结霜等对外层的内/外表面产生不同程度的影响。例如减低外层内的光源体所发出的光源的亮度和影响灯管的外观。再者，由于尘埃长期积聚在灯管内而无法清洁，工作时间越长，尘埃积聚得越多，导致灯管的工作温度增加，从而令灯管短路或开路而销毁，严重会导致火灾。
另一方面，由于普遍的灯管存在空间不足的问题而无法为灯管加入一些保护的安全线路。常见的保护安全线路为EMC(Electromagnetic Compatibility)电磁兼容性滤波器。在灯管工作期间，周边的大型电磁设备如水泵、风机、压缩机、马达或发电机等启动和运行期间会产生电磁干扰，这些电磁干扰可能击穿灯管内的光源体、引致发黑、烧毁外主体和冲击电子组件或线路。此线路的好处是可以防止以上情况的发生。可惜一般的EMC线路及其使用的电子组件大小都无法安装在现有的灯管的有限空间内。
发明内容
为了解决上述的问题，本发明提供了另外一种灯管。该灯管包括内发光源体、外透光体、真空封口盖、滤波驱动器和电源输入插头。其中外透光体由内外两层真空玻璃组成，真空玻璃的材料直径不少于7毫米而长度不少于60毫米，两层真空玻璃之间存在夹层，而夹层中气压低于11-1帕，并且内壁都镀有低幅射膜。外透光体和内发光源体之间的空气被完全抽出，并通过真空封口盖封密，使外透光体和内发光源体之间形成真空状态。这样做可以有效防止悬浮粒子随着空气进入外透光体而产生不同程度的自然影响，如结霜、结雾、结露、污渍内藏和尘埃积聚等而大大减低灯管的正常亮度输出及影响外观。
在本发明的一个实施例中，滤波驱动器分为两部份：驱动器和EMC(Electromagnetic Compatibility)电磁兼容性滤波器。针对灯管空间不足的问题，电磁兼容性滤波器的线路有专用设计以减少其体积。
在本发明的另一个实施例中，电源输入插头安装在灯管的两端，且两端电源输入插头均可连接输入电源以及可以以串联方式把多个灯管连接在一起。
在本发明的另一个实施例中，内发光源体使用T1至T12型号的日光灯管、冷阴发光体、二极发光体或非标准的光源体。
在本发明的另一个实施例中，真空封口盖之主要材料为不同的塑料物料或五金钢材等。
附图说明
参照本说明书的余下部分和附图可以对本发明的性能和优点作进一步的理解；这些附图中同一个组件的标号相同。在某些情况下，子标记被放在某个标号与连字符后面以表示许多相似组件的其中一个。当提到某个标号但没有特别写明某一个已有的子标记时，就是指所有这些类似的组件。
图1显示了本发明一个实施例中滤波驱动器内置于外透光体内的实施图。
图2显示了本发明一个实施例中滤波驱动器外置于外透光体的实施图。
图3显示了本发明一个实施例中滤波驱动器的线路图。
具体实施方式
参照图1，根据本发明的一个实施例，灯管包括内发光源体20、外透光体30、真空封口盖40、滤波驱动器50和电源输入插头60。内发光源体20使用T1至T12型号的日光灯管、冷阴发光体(CCFL)、二极发光体(LED)或非标准的光原体。外透光体30由内外两层真空玻璃组成，真空玻璃的材料直径不少于7毫米(mm)而长度不少于60mm，两层真空玻璃之间存在夹层，而夹层中气压低于11-1帕(pa)，并且内壁都镀有低幅射膜，因此可以减低幅射传热。外透光体30的真空玻璃具有硬度高、热阻高、抗风压性能高、隔声性能好等的优点，因此可以有效地杜绝结霜、结雾、尘埃积聚等顽固的老问题，并有效增加采亮度分布以及减低紫外线输出。而耐高温的优点可把内发光源体20的工作温度保持稳定而不容易透过外透光体30释放出去，从而有效提高节能效率。
根据本发明的一个实施例，真空封口盖40之主要材料为不同的塑料物料或五金钢材等。真空封口盖40的主要作用是当外透光体30和内发光源体20之间的空气被完全抽出，立刻用真空封口盖40封密，使外透光体30和内发光源体20之间形成真空状态。在本发明的一个示范实施例中，电源输入插头60安装在灯管的两端，且两端电源输入插头60均可连接输入电源以及可以以串联方式把多个灯管连接在一起。
图1是本发明一个实施例中滤波驱动器内置于外透光体内的实施图。如图1所示，内发光源体20置于外透光体30内，外透光体30和内发光源体20之间的空气被完全抽出。然后把滤波驱动器50也置入外透光体30中，再用真空封口盖40封密，使外透光体30和内发光源体20之间形成真空状态。最后把电源输入插头60安装在灯管的两端。
除了把滤波驱动器50内置于外透光体30内，根据本发明的另一个实施例，滤波驱动器50也可以外置于外透光体30。图2是本发明一个实施例中滤波驱动器50外置于外透光体30的实施图。同样地，灯管包括内发光源体20、外透光体30、真空封口盖40、滤波驱动器50和电源输入插头60。但是，当外透光体30和内发光源体20之间的空气被完全抽出，就立刻用真空封口盖40封密，使外透光体30和内发光源体20之间形成真空状态。然后把滤波驱动器50安装在外透光体30的两端，最后把电源输入插头60安装在灯管的两端。
根据本发明的进一个实施例，滤波驱动器50分为两部份：驱动器和EMC(Electromagnetic Compatibility)电磁兼容性滤波器。针对灯管空间不足的问题，电磁兼容性滤波器的线路有专用设计以减少其体积，使其可以安装到灯管上。图3显示了本发明一个实施例中滤波驱动器50的线路图。如图3所示，电磁兼容性滤波器的线路70和驱动器的线路80连结在一起，专用的线路设计不但可使滤波驱动器50的体积变小，还有效令内发光源体20的光分布面扩大而增加照明亮度。而且，加入了电磁兼容性滤波器，可以抗衡周边的大型电磁设备如水泵、风机、压缩机、马达或发电机等启动和运行期间产生的电磁干扰，因而增加了灯管的安全性和稳定性。
虽然本发明的不同实施例已经在以上陈述，但应该理解为这些实施例只作为例子而已但不是限制。本领域的技术人员会理解不同形式的变更和细节也可以实施本发明但没有偏离本发明权利要求书中的精神和范围。本发明应理解为不只限于这些例子。所以，本发明的广泛程度和范围不应该被以上所述的示范实施例所限制，而应该只被下列的权利要求书和其相同的意思所定义。
内发光源体20和外透光体30的形状不限，可以是长方形、椭圆形或其他形状。真空封口盖40可以用不同的材料来制造。滤波驱动器50可以用不同的组件来组合。内发光源体20的亮度和颜色也不限。
