Description

凹状空腔的荧光灯系统
技术领域
本发明涉及一种荧光灯，并且特别涉及一种无电极荧光灯。尤其涉及一种具有凹状空腔的荧光灯。
背景技术
市场上越来越需要其形状更小和更亮的更有效的荧光灯，传统电极荧光灯面临困境。由于反射损失，覆盖传统电极放电的A灯泡造成大约8％的流明减小。电极灯的管状磷光层(其中产生热量)和A形外罩(其中热量逸出系统)导致系统固有温度更高。在A形电极系统中，更高温度在产生更高流明(例如，大于15W，800流明)中产生问题。
无电极荧光放电灯已经解决了许多与试图销售紧凑荧光灯相关的问题。放电腔室可制成A形，使其不需要外罩。磷光体位于灯的A形部分上，使得冷却更加有效。这种紧凑的无电极灯已经在市场上销售很久，并基本上包括两种不同的类型；一种类型是具有单独镇流器的感应驱动等离子放电，另一种类型是整体镇流器的感应驱动放电。后一类型的无电极放电灯通常工作正常；但是，存在热量、对于某些使用来说具有不充足的RF屏蔽以及汞齐温度控制不充分的问题。
发明内容
因此，本发明的目的在于消除现有技术的缺陷。
本发明的另一目的在于提高无电极荧光灯的操作。
本发明的再一目的在于一种具有更好的汞齐温度控制的荧光灯。
本发明的又一目的在于以合理的成本提供具有良好RF屏蔽的无电极荧光灯。
在本发明的一个方面，这些目的通过提供一种无电极荧光灯来实现，该荧光灯具有灼热器、含有镇流器的镇流器壳体和连接到电源的底座。凹状空腔设置在灼热器内，并且汞齐容座与灼热器连通。壳体盖将灼热器连接到灼热器壳体上，并且具有形成镇流器壳体一部分的EMI盖。EMI盖具有底部以及闭合上部并其中带有开口的盖。汞齐容座延伸通过开口并进入镇流器壳体，这有助于调节汞齐的温度。镇流器壳体提供出色的RF屏蔽，使得灯在以前多种不可使用的场合中进行多种使用。
附图说明
图1是本发明实施例的部分截面形式的立视图；以及
图2是本发明镇流器壳体的放大截面图。
具体实施方式
为了更好理解本发明及其其他目的、优点和能力，结合附图对于以下说明和所附权利要求进行参考。
现在更特别地参考附图，在图1中示出具有灼热器20、含有镇流器的镇流器壳体30和连接到电源上的螺旋底座50的无电极荧光灯10。凹状空腔60形成在灼热器20内，并且含有汞齐75的汞齐容座70形成凹状部分的一部分并与灼热器20连通。由适当塑料形成的壳体盖80将灼热器20连接到镇流器壳体30上，并且适当的粘合剂31将灼热器固定装置壳体盖80上。EMI盖90形成安装在镇流器壳体30内的插件，该壳体也由适当塑料制成，并具有底部100以及闭合上部140并其中具有开口120的EMI盖110。EMI盖90和EMI盖110最好由0.5mm黄铜制成。汞齐容座70延伸通过开口120并进入盖90内。为了固定汞齐位置，改变开口尺寸使得汞齐尖端温度得以调整，并且根据汞齐温度，控制系统流明输出、效率、CCT和CRI。
以线绕铁磁管150为形式的连接器定位在凹状空腔60内并包括隔热连接器盖152和由陶瓷纸形成并含有高纯度氧化铝基的耐火纤维的连接器底座154，耐火纤维例如是从Cotronics Corporation得到的Rescor 300。Kapton带可用来将线绕组连接在铁磁芯的顶部和底部上。灼热器壳体绝缘体155安装在凹状部分内，并还可用来支承铁磁芯。壳体绝缘体155最好由黑尼龙制成。凸缘156将壳体绝缘体155在镇流器壳体30内对中。
EMI盖90包括含有镇流器部件170的镇流器板160，并且镇流器板靠近盖90的底部100定位，并且垫片180靠近盖90的上部140定位并贴靠盖110。垫片180将镇流器板160保持就位，并为灯100提供轴向冲击的缓冲。垫片180最好由硅酮发泡橡胶制成。
EMI盖90另外包括最好由尼龙形成并围绕镇流器板160而且包括向内延伸凸缘200的环形对中环190，镇流器板160静置在凸缘200上以便在镇流器板160的底部210和EMI盖90的底部100之间保持固定距离。
EMI盖90还含有在粘性状态下施加以便包围镇流器板160的底部210上的表面安装部件的镇流器散热器220，由此形成电绝缘和热接触以便在镇流器板160上提供镇流器160的冷却。在本发明的优选实施例中，镇流器散热器包括导热环氧树脂和从Dow Croning得到的5-6克的Sylgard 165。
DC板230可定位在螺旋底座50内并最好通过大约0.005英寸厚的Nomex的绝缘盘235与EMI盖90绝缘。
例如EMI盖110内的240和EMI盖90的底部100内的241的开口设置成使得所需连接线旋入。
因此提供一种无电极荧光灯，由于RF屏蔽以及出色的汞齐温度控制，该荧光灯与相邻电气部件具有最小的干扰。
虽然已经描述和说明认为是本发明优选的实施例，本领域普通技术人员可以进行不同变化和改型而不偏离所附权利要求限定的本发明的范围。
