Abstract
微型化荧光灯冷阴极用的释出汞汽的吸气带,上有载承着释出汞汽的材料Ti3Hg与不蒸发的吸气金属Zr(84%)-Al(16%)的混合物的凹坑。凹坑两两成对,两对之间距大于各对中两凹坑之间距。此种带可切成含有两个凹坑的短带,将后者绕其所在平面内居于此两凹坑之中且垂直于带长的方向的轴转过约180°而折叠,再焊到一支承件上用作微型荧光灯的冷阴极。此阴极在制造过程中可加热至释出汞汽,随后起到冷阴极与吸气装置的作用。
Description
配汞用的吸气装置在荧光灯工艺中已是周知的,例如可参看日本实用新案申请公开号50-10679与美国专利号3722976、3657589以及3733194等。
但是,上述专利公开的内容并未涉及冷阴极荧光灯的微型化技术,而这样的荧光灯。例如乃是汽车仪表盘、袖珍电视机以及类似设备中液晶显示装置背底照明所需用的,或者也可单纯用于照明目的。
曾对生产微型的冷阴极荧光灯作过一种特殊的尝试,即用两小片镀以Ti3Hg与Zr(84%)-Al(916%)合金的带,点焊到金属丝支承的引线上。然而,这样的阴极仍然较大,而且有释出的汞不足以确保荧光灯所需寿命的缺点。
本发明的目的之一在于提供一种微型化荧光灯冷阴极用的释出汞汽的吸气带,在此带中有一列连续的凹坑,以之载承一种释出汞汽材料与一种不蒸发的吸气金属的混合物,这一列凹坑由相续的一对对独立的凹坑组成,每对凹坑间所隔距离大于各对中两独立凹坑间的距离,这样的带用来制造微型荧光灯的冷阴极。
本发明的目的之二在于提供一种用来制造微型荧光灯的经改进的冷阴极。
本发明的目的之三在于提供一种改进的微型荧光灯。
参看以下说明与附图,将可明了本发明的上述目的与其它目的以及本发明的优点。在附图中,
图1是用于荧光灯中先有工艺的冷阴极的透视图;
图2是本发明之释出汞的金属吸气带的平面图;
图3是沿图2中3-3′线的放大的横剖面图;
图4是用图2所示之带的一部分生产出的冷阴极的透视图;
图5是图4中之冷阴极沿其中箭头指向所剖取的示意图;而
图6是采用了本发明之冷阴极的微型荧光灯的横剖面图。
现来参看附图,特别要参看图1,其中示明了先有工艺中的一种冷阴极,它由两片镀镍的铁带102、102′组成。带102的朝外表面上加压接合着由粉状的Zr(84%)-Al(16%)一种不蒸发的吸气合金组成的一层膜106。带102′的外表面(未示明)也有类似的膜层。带102′的朝内表面108则有一层粉状的释出汞的Ti3Hg金属互化物膜110。带102、102′能够由市售的牌号为St101-505/CTL/NI6.3-3的一种连续式的长带(意大利米兰市SAES GETTERS S.P.A生产)上切取下。
带102、102′是在点114、114′处焊合到支承件112、112′上的。焊合点114、114′必须取在此种带的边界处,如在带102的边界116处。这是为了能在冷阴极***荧光管之前的组装过程中,避免释出汞的任何可能性,同时避免破坏Zr-Al合金的吸气性质。
由于带102、102′的尺寸为宽约0.65cm,长约0.6cm,因而使它们与其支承电极精确定位到一起是极其困难的。这在将释出汞的合金与不蒸发的吸气合金焊合过程中,会冒过热的严重风险。此外,想要使此冷阴极进一步微型化,还会导致减少存在的Ti3Hg量,从而也就降低了此种荧光灯中释出
的汞量。同样,还会使现存的不蒸发的吸气材料减少到,不能保证在荧光灯的寿命期内可以充分地除去所释出的危险的残存气体。
参看图2,其中示明了本发明的金属带200。此金属带200可取任何一种适于支承释出汞汽的材料和不蒸发的吸气材料的金属制成。带200最好采用镀镍的铁带。带200上有连续的一列凹坑202、202′,204、204′,206、206′。凹坑202、202′在此带内构成一对独立的凹坑,相续的凹坑204、204′组成了另一对独立的凹坑,而接着的两个独立凹坑206、206′则形成又一对凹坑,等等。各对凹坑的间距大于分开对中两独立凹坑的间距。这样的凹坑最好取图2中所示的大致卵形,使其长度大于宽度。图中所示的这种卵形也可描述为跑道形或椭圆形。
参看图3,其中示明了图2中之凹坑204沿3-3′线的横剖面300。
横剖面300亦表明出含凹坑204的金属带。凹坑204内压装有释出汞蒸汽的材料302。释出汞蒸汽的材料302最好由粉状的金属互化物Ti3Hg与一种粉状的不蒸发的吸气金属组成,而后一种材料以包含合金Zr(84%)-Al(16%)为宜。
参看图4,其中示明了本发明的冷阴极400。冷阴极400是由小长度的段402构成,例如在图2中沿α与β所指出的线切割下带20C的一小段构成。然后将带402依图4与图2中都标出的γ线折叠。γ线处于带402的平面内且居于402的两个凹坑之间并垂直于带的长向。带402是通过一约180°的角度弯曲的。如图4所示,所进行的弯曲是让凹坑的凹面朝外,这便可使阴极占据的空间有可能最小。如图4与5所示,阴极400可以焊接到金属线支承件404上。这里的金属线支承件404示明是在阴极400之内,但应认识到,这种小长度的带402可以重叠折合得更为挨近,因而金属丝支承件有可能在冷阴极400的外面。
最后参看图6,其中示明了一种微型荧光灯600,它包括一圆筒状玻璃泡壳602与端部密封件604、604′。此微型荧光灯600在其内部分别由密封件604、604′保持着两个冷阴极400、400′。
例
取宽2.5mm的一长段镀镍铁带,在其上面加工出一列相续的凹坑,这些凹坑按顺序两两成对,每对包括两个独立的凹坑。各凹坑宽约1.5mm,而长约3.5mm。各对间两凹坑之间距为2.5mm,而两邻对间的距离为5mm。每个凹坑充填以如下5mg的混合物:按重量计,50%的金属互化物Ti3Hg与50%的Zr(84%)-Al(16%)合金这样一种不蒸发的吸气材料。从上述长带切下一小段,按前述方式折叠,然后焊到金属丝的支承件上,由此便制成了冷阴极。用两个这样的电极生产出为图6所示的微型荧光灯。在制造过程中可加热此阴极至释出汞,随后起到冷阴极与吸气装置的作用。
为使熟悉本项工艺的人能更好地实施本发明,上面对照某些用于此目的的最佳实施例,已对本发明作了相当详细的描述,虽然如此,但应承认在不脱离后附权利要求书的精神与范围的前提下,是可以采用其它改型的。
