Abstract
本发明涉及一种高压金属卤化物灯,包括放电管,具有的可电离填充物含有一种或多种金属,其中有Hg、卤化物和稀有气体,放电管包括具有实质上含W的棒的电极。灯工作时在放电管内保持W－卤化物循环。根据本发明,放电管含有氧分配器。
Description
本发明涉及装配有放电管的高压金属卤化物灯，放电管中的可电离填充物含有一种或多种金属，其中有Hg、卤化物和稀有气体，该放电管包括的电极具有实质上含W的棒，灯工作时在放电管中保持W-卤化物循环。
开头所限定类型的灯已公知于US3521110。用做白光光源的已知的灯具有高的发光效率，其放电管带有石英玻璃的壁。其它适用的壁材料是陶瓷。这里的陶瓷壁应理解为是指折射材料，例如是单晶金属氧化物(例如蓝宝石)、多晶金属氧化物(例如多晶烧结氧化铝，钇铝石榴石或氧化钇)和多晶非氧化材料(例如氮化铝)。
W卤化物循环延长了灯的使用寿命，因为这样可以避免从电极蒸发的W淀积在放电管壁的整个表面上。产生W卤化物循环的条件是灯工作时放电管中存在少量自由氧。自由氧一般来源于灯的制造过程中产生的沾染物，当灯处于工作状态时从其中释放。已经确认，在与放电管的填充物成分的反应影响下，氧从放电管壁释放出来。
已知灯的缺点是灯工作状态下放电管中可获得的氧量不可控制。在浓度过小的情况，将难以在灯的工作过程中充分保持W卤化物循环。在浓度过大的情况，尤其是将腐蚀W棒电极。从灯的正常工作所需的制造精度来看，氧浓度过小的可能性是个相当大的问题。
文献中实际上已经提出在填充物中掺入氧，例如以卤氧化物的形式，如三卤氧化铌(US4672267)或者以HgO的形式(US3720855)。这种掺入的缺点是，如此制造的灯即使使用分子稳定剂也不能稳定发光。另一个缺点是HgO有毒。使用Nb的严重缺点是其存在溶解于W中的倾向，因此降低了W电极的熔点，结果W将发生更强的蒸发。在非点火灯中存在的自由氧对灯的点火有不利的影响，因此应予避免。
本发明的目的在于提供一种解决上述不利影响的措施。为此目的，由开头所限定类型的根据本发明的灯的特征在于放电管含有氧分配器。
根据本发明的灯的优点在于，在灯的工作过程中按控制方式向放电管馈入氧。另外的优点是在灯的使用寿命期间能够进行掺入。在根据本发明的灯的第一优选实施例中，氧分配器含有WO2。在根据本发明的灯的另一个优选实施例中，氧分配器含有CaO。WO2和CaO的优点在于，当施加O2时，例如作为填充成分通常施加于放电灯的元素被释放。在根据本发明的具有陶瓷放电管的灯中最好使用含CaO的氧分配器。这种灯的意外优点是Ca的出现不仅起到保持W卤化物循环的作用，而且还有助于发送红色和兰色的光谱。于是，可以制造其发射光具有高达3500K的色温Tc的灯，一般彩色重现指数Ra值超过80。
通过参考以下实施例将可了解和解释本发明的这些和其它方案。
图中：
图1显示了根据本发明的一种灯；
图2显示了根据本发明的另一个灯。
图1所示高压金属卤化物放电灯具有气密、透光的石英玻璃放电管1。放电管具有稀有气体和金属卤化物的可电离填充物。所示灯的填充物包括汞，以及钠、铟、铊的碘化物，和由99.8体积％氖气和0.2体积％氪的混合物组成的填充压力为50mbar的稀有气体。填充物还具有含WO2的氧分配器，例如以浸渍WO2的陶瓷载体的形式。放电管中的每个电极2具有实质上含W的棒6，每个棒连接于导体3，在图中为钼导体，该导体3经过放电管向外引出并且通过电导体7和8连接于灯头5。所示的灯具有装载灯头5的硬玻璃外灯壳4。所示的灯的功耗是400W。
在图2所示灯的情况，金属卤化物灯表现为陶瓷壁放电管3的剖面图，并未按比例，放电管包围放电空间11，放电空间含有可电离填充物，所示例中不仅含有Hg，而且还含有Na和Tl的卤化物。填充物还包括含CaO的氧分配器，例如以浸渍CaO的陶瓷载体的形式。两个电极4、5具有电极棒44、54和顶端45、55，布置在放电管中并且均由W组成。放电管在一侧分别由陶瓷突出塞34、35封闭，该陶瓷突出塞以一定的空隙紧密围绕引到放电管中的电极4，5的引线40，41；50，51。陶瓷突出塞在离开放电管的一端用熔融陶瓷接头10按气密方式连接。如图所示的放电管本身的结构是公知的，例如可见EP-0587238。放电管被一端具有灯头2的外灯壳1围绕。灯工作时电极4、5之间产生放电。电极4通过导体8连接于构成部分灯头2的第一电触点，电极5通过导体9连接于构成部分灯头2的第二电触点。
如图2所示的灯的实施例中，灯的标称功率是70W，该灯具有90V的标称灯电压。放电管的透明壁厚度是0.8mm。放电管内径是6.85mm，电极顶端之间的距离是7mm。灯的可电离填充物除了含有4.8mg的Hg，还含有7mg的(Na+Tl+Ca)碘化物，重量百分比组成是28.8，10.7和60.5。放电管还含有填充压力为300mbar的Ar作为启动增强剂。在灯的工作过程中，Tkp是1210K。灯发光时的光通量是100小时为901m/W。发光的色温Tc是3150K。一般彩色重现指数Ra是84。
