Description

紫外线灯管封装的方法及结构 技术领域
本发明是关于一种紫外线灯管封装的方法及结构，尤其是一种不含荧光粉的紫外线灯管。
背景技术
一般紫外线(Ultraviolet ray)的光谱长度分为UVA、UVB以及UVC，紫外线的UVA的波长为320-400nm(纳米)，其又称为长波紫外线，紫外线的UVB的波长为280-320nm(纳米)，其又称为中波紫外线，紫外线的UVC的波长为100-280nm(纳米)，其又称为短波紫外线，而这三种不同的紫外光又分别用于杀菌、固化、辨识以及场所等。
紫外线用于杀菌用的光线为UVC，其破坏及改变微生物的DNA(脱氧核糖核酸)结构，使细菌或微生物当场死亡或无法繁殖后代，使其达到杀菌的目的。紫外光杀菌灯的发光谱线主要有254nm(纳米)和185nm(纳米)，254nm(纳米)的紫外线通过照射微生物的DNA来杀灭细菌，185nm(纳米)的紫外线可将空气中的O 2变成O 3(臭氧)，臭氧具有强氧化作用，可有效地杀灭细菌，臭氧的弥散性恰好可弥补由于紫外线只沿直线传播、消毒有死角的缺点。紫外线杀菌属于纯物理消毒方法，具有简单便捷、广谱高效、无二次污染、便于管理和实现自动化等优点，随着各种新型设计的紫外线灯管的推出，紫外线杀菌的应用范围也不断在扩大。
于紫外线灯的制作中，UVA、UVB其光谱仍然依靠荧光粉产生，唯独UVC使用254nm(纳米)以下就直接用汞气(汞蒸气)的发光光谱，而汞的发光光谱为253.7nm(纳米)，其就不用使用荧光粉，且于紫外线光谱中，此波段的杀菌能力最好，但在制造上也相对困难。
现今的技术中，一般都是利用钨丝电极进行制作，其发射电子原理为钨丝电极利用溅射效应来启动点灯的程序，因此，每点灯一次，就必须产生溅射效应。而在溅射效应的时候会顺便将蒸气汞氧化成氧化汞(汞合金)，此氧化汞就会附着在玻璃管内层且靠近钨丝电极的地方，长时间不断地产生溅射效应，就会使玻璃管内层变成黑色的一圈，此俗称黑头；且氧化汞也会随着时间的使用，慢慢地布满整个灯管内部，此俗称黑管。如果是用于紫外线灯管，使用时间久了而产生黑管，此黑管将会造成透光率下降而降低紫外线的能量，再者，由于溅射效应将汞蒸气氧化，其也相对减少汞蒸气，如此也无法提供正常的放射能量，这也是现今紫外线灯管使用寿命短的原因之一。一般现今紫外线灯管只能使用5000-8000小时，甚至更短。

具体实施方式
为了使本发明的结构特征及所达成的功效有更进一步的了解与认识，特用较佳的实施例及配合详细的说明，说明如下：
本发明针对现有紫外线灯管结构进行发明。一般现有技术都是利用钨丝电极进行制作，其发射电子原理为钨丝电极利用溅射效应来启动点灯的程序，因此，每点灯一次，就必须产生溅射效应，而在溅射效应的时候会顺便将蒸气汞氧化成氧化汞(汞合金)，此氧化汞就会附着在玻璃管内层且靠近钨丝电极的地方，长时间不断地产生溅射效应，就会使玻璃管内层变成黑色的一圈，此俗称黑头，且氧化汞也会随着时间的使用，慢慢地布满整个灯管内部，此俗称黑管，如果是用于紫外线灯管，使用时间久了而产生黑管，此黑管将会造成透光率下降而降低紫外线的能量而失效，再者，由于溅射效应将汞蒸气氧化，其也相对减少汞蒸气，如此也无法提供正常的放射能量，这也是现今紫外线灯管使用寿命短的原因之一，一般现今紫外线灯管只能使用5000-8000小时，甚至更短，故，本发明为了让紫外线灯管的黑管或黑头现象得以控制，发明出一种陶瓷电及封装方法及结构。其利用陶瓷电极来启动电灯的程序，因为没有钨丝电极，所以就不会产生溅射效应，故，其不但不会有黑管或黑头，且汞蒸气也不会被氧化，因此，其可以维持紫外线的透光率，也因此延长使用寿命，且使用寿命为20000小时。相较于先前技术，其大幅提升使用寿命，如此，就可以减少使用汞，进而达到节能减碳的要求。

步骤S3：加热一第一玻璃管的二端管口，其中一端管口连接该第一陶瓷电极另一侧的一第二凹槽；
步骤S3对应图2B，如图所示，分别加热一第一玻璃管4的一第一连接部42的一第一管口425以及一第二连接部44的一第二管口445并对其进行扩管，接着将所述第一玻璃管4的所述第一连接部42连接所述第一陶瓷电极3的一端的所述第二凹槽36内，且所述第二凹槽36设置于所述第一中空本体32的一侧开口处，使所述第一中空本体32能够连通所述第一玻璃管4。
步骤S5：该第一玻璃管的另一端连接一第二陶瓷电极一侧的一第三凹槽；

步骤S7：设置一通气件至该第二陶瓷电极一侧的一第四凹槽；
步骤S7对应图2D、图2E以及图2F，如图所示，封装一通气件6至所述第二陶瓷电极5一侧的所述第四凹槽56上，且所述通气件6为一玻璃管体，其具有一开口端62以及一第一流道64，所述开口端62设置于所述通气件6的一侧，且所述通气件6的相对于所述开口端62的另一侧连接所述第四凹槽56，所述通气件6内设置所述第一流道64，且所述第一流道64的两侧分别连通所述开口端62以及所述第二中空本体52，使所述通气件6能够通过所述第一流道64连通所述第一玻璃管4，此外所述第一玻璃管4的所述第一连接部42通过一胶体35连接于所述第一陶瓷电极3的所述第二凹槽36内，以及所述第二连接部44通过所述胶体35连接于所述第二陶瓷电极5的所述第三凹槽54内，且所述胶体35为玻璃胶剂。
步骤S9：由该通气件对该第一玻璃管抽真空；
步骤S9对应图2G，如图所示，因为所述通气件6设置于所述第四凹槽56后，且所述通气件6经由所述第二陶瓷电极5的所述第二中空本体52连通至所述第一玻璃管4，最后连通至所述第一陶瓷电极3的所述第一中空本体32，此外所述第一陶瓷电极3的所述第一凹槽34上由一第一密封件2进行密封，接着由所述通气件6的所述开口端62经由所述第一流道64对所述第一玻璃管4内进行抽真空，使得所述第一玻璃管4内部的空气压力呈现负压状态。
步骤S11：由该通气件对该第一玻璃管输入一气体；
步骤S11对应图2H，如图所示，当由所述开口端62经由所述第一流道64对所述第一玻璃管4抽真空后，再由所述开口端62输入一气体7至所述第一玻璃管4内，且所述气体7输入至所述第一玻璃管4后，所述第一玻璃管4内的空气压力依然是小于外部的空气压力，使所述第一玻璃管4内的状态依然是负压状态，其中输入的所述气体7包含汞气(汞蒸气)、氖气(Ne)或氩气(Ar)，或者，所述气体7内也可灌入汞气，如果不使用汞气，则可使用氙气(Xe)气来代替。
步骤S13：加热密封该通气件的该开口端。
步骤S13对应图2I，当输入所述气体7后，接着加热所述通气件6的所述开口端 62，所述通气件6的材质为玻璃、使所述开口端62遇热会膨胀后能够密合，又，所述第一玻璃管4内呈现负压，当开口端62遇热膨胀后，所述开口端62会因为外部压力大于所述第一玻璃管4内部压力而向内缩，进而密封所述开口端62，使得所述通气件6的所述开口端62密封后变成一第二密封件68。通过所述第一密封件2密封于所述第一陶瓷电极3的所述第一凹槽34以及所述通气件6的所述开口端62密封后，能够将所述气体7完全锁住于所述第一玻璃管4内。

请再继续参阅图3A，其为本发明的第二实施例的步骤示意图，图3B为本发明的第二实施例的步骤放大示意图，图3C为本发明的第二实施例的步骤示意图，本实施例与第一实施例的差别在于所述第二陶瓷电极5的所述第三凹槽54的所述第三半径R 21以及所述第四凹槽56的所述第四半径R 22，本实施例的所述第三半径R 21大于所述第四半径R 22，且所述第一玻璃管4扩管的管径对应所述第三半径R 21，也就是说，所述第一玻璃管4的所述第二管口445的管径需要小于所述第三半径R 21，更进一步说明，所述第二管口445的管径加上所述第二连接部44的厚度需要小于或等于所述第三凹槽54，如此所述第二连接部44才能够设置于所述第三凹槽54内，以及设置于所述第二陶瓷电极5另一侧并相对于所述第三凹槽54的所述第四凹槽56，所述第四凹槽56的所述第四半径R 22小于所述第三半径R 21，且所述第三凹槽54与所述第四凹槽56之间连接所述第二中空本体52，使所述第四凹槽56经由所述第二中空本体52连通所述第一玻璃管4，所述通气件6连接所述第二陶瓷电极5的所述第四凹槽56内，且所述通气件6连接于所述第四凹槽56内的一端的半径对应所述第四半径R 22，接着由所述开口端62经由所述第一流道64对所述第一玻璃管4内进行抽真空，使所述第一玻璃管4内呈现负压，再由所述开口端62经由所述第一流道64输送所述气体7至所述第一玻璃管4内，此时，因为所述第三半径R 21大于所述第四半径R 22，进而使输送至所述第一玻璃管4内的所述气体7较不易散出，且所述第四半径R 22相对于所述第三半径R 21小，使得所述通气件6的体积也相对缩小，当进行加热密封所述开口端62时，其因为所述通气件6的整体的 体积缩小，使得加热时，所述通气件6材质的玻璃膨胀，使其更能够轻易地将其进行密封。
接着，请再继续参阅图4A，其为本发明的第三实施例的立体示意图，图4B至图4D，其为第三实施例的局部放大剖视示意图，如图所示，本发明为一种紫外线灯管封装的结构1，其包含一第一密封件2、一第一陶瓷电极3、一第一玻璃管4、一第二陶瓷电极5以及一第二密封件68。
