利用无线电的高频、射频或微波段的电波能量去激发荧光灯中的汞蒸汽，使汞原子的 外层电子获取能量而发出紫外光子，它被涂在灯壁上的荧光粉吸收便发出可见光的无极荧 光灯， 在 20世纪 90年代初试验成 ¾并从 90年代中后期投放市场以来， 因其光谱的连续 性好、 启动无闪烁、 允许电源电压波动大， 故被各国照明界誉为至今最佳的绿色电光源。
早在 1970年 J.M.Anderson在 US3500118号专利中提出了外置感应荧光灯的线圈结 构， 是在一个环形密闭的波壳外安置感应线圈。
在 1977年 Hollister在 US4010400号专利中提出了在低电压大电流的情况下无极荧光 灯的光效会更高，釆用铁氧体磁芯材料，在铁氧体磁芯上绕有线圈耦合，上述专利给出了 无极灯及外耦合型无极灯的基本结构， 并逐步改进。
1998年美国专利 US005932961A中公开了辅助启动的安置位置， 19%年 PCT专利 W09710610 中提出了一种无极荧光灯， 在结构上没有实质上的变化， 但在充入的气体压 力方面强调了低于 0.5乇的汞蒸气和缓冲气体， 及大于等于 2A的放电电流的工作参数。
1991年日本松下公司的 EverCight无极灯、 1994年 GE通用公司的 Genura无极灯、 1997年飞利浦公司的 LQ无极灯以及 2004年上海宏源照明的双规结构灯管的无极荧光灯， 它们的工作原理大都一致， 都属于无极荧光灯 （无极荧光灯)， 它们的工作原理就是将线 圈绕在磁环上形成耦合器，磁环扣在灯管两端， 由 IC电路驱动耦合器，使之产生 250KHZ (国家标准号： QB/T2871-2007) 的交流电能激励汞原子， 使其将电能转换成磁能， 又将 磁能转换成光能进行照明。这些无极荧光灯的灯管内所充的多是高纯氪气和高纯氩气的混 合气体，但充入此类填充气体的无极灯在长期处于黑暗和低温中时，灯本身对启动电压要 求很高， 并且在 -25Ό或更低温度时， 灯无法启动， 从而加重了镇流器的负担， 结果使镇 流器早期损坏的几率大大增加。 由图 1可见： 气体 1是髙纯氪气和高纯氩气的混合气体， 通常以高纯氪气 20%，高纯氩气 80%的混合作为填充气体，荧光粉 2为涂复在玻璃灯管 3 内部，铟网 4被固定在一个小玻璃管内，接桥 5是玻璃灯管的桥接处，汞齐 6固定在一个 排气小玻璃管内。
为了克服上述的缺陷， 在中国专利号为 200410017576.5公开了一种具有双规结构灯 管的无极荧光灯，这种灯利用同时该灯管采用多个铟网作为辅助启动，用来解决大功率回 路长的无极荧光灯灯管启动困难的问题， 这种方法确实提高了灯泡的启动性能。 由图 2 可见：桥接玻璃 10的一端被焊接在焊接处 20，桥接玻璃 10的另一端被悍接在焊接处 30， 桥接玻璃 40的一端被焊接在焊接处 50， 桥接玻璃 40的另一端被焊接在焊接处 60， 封接 玻璃 90和封接玻璃 110分别被焊接在灯管玻璃 70的两端形成上发光体 200，封接玻璃 100 和封接玻璃 120分别被焊接在灯管玻璃 80的两端形成下发光体 300。参看图 3，上发光体 200具有两个焊接面 210、 230， 两个焊接面 210、 230对应两个感应面 270、 280， 下发光 体 300具有两个焊接面 320、 340， 两个焊接面 320、 340 ¾]·应两个感应面 350、 360。参看 图 4， 上、下发光体 200、 300之间通过焊接处 410、 420焊接在一起， 在焊接处 410、 420 处设置有功率耦合器 510、 520。 可以看出， 它是采用多个铟网作为辅助启动， 用来解决 大功率回路长和灯在长期处于黑暗和低温中无极灯启动困难的问题，确实提高了灯泡的启 动性能， 但也存在由于铟网的数量增加， 同时也增加了玻璃制作工艺、 接桥工艺难度高、 封接多， 产品一致性难控制等因数， 制约了无极灯的普及使用。
目前诸多有关于无极荧光灯的技术方案基本上从灯管的结构及配套的高频镇流器入 手，来设计整个照明装置。但对其整个照明装置安置在密闭灯具时， 灯管和镇流器所产生 的高温问题， 以及在低温状态或黑暗环境时无极灯不能正常启动的问题，均未给出相关的 技术解决方案。 由于目前的无极荧光灯没有设计导热、散热装置， 当磁环上的绕线圈通入 电流后会在磁体上产生强度较高的涡流,这种涡流的能耗将转化成焦耳一楞次热释放到磁 体上。 随着通电工作时间的增加， 磁体上所产生的大量热量会导致磁体的温度急剧上升， 从而降低磁体的性能， 增加涡流损耗， 进而降低灯泡内高频电磁场能量及减少荧光量 (即 降低灯的工作功率， 减少光通量)，特别是将灯管和镇流器安装在密闭灯具里面时， 其磁体 上的热量无法及时散走，直到超过磁体的居里温度时，磁体会丧失功能而使灯停止工作或 产生故障。
由于镇流器是采用 100〜300KHz 的驱动频率， 虽然是高频无极灯 （2.65M) 的十份 之一， 但也存在 EMC (电磁兼容） 传导干扰严重， 灯管辐射大， 不仅对电网产生危害， 且对自身可靠运行带来烕胁， 应用范围受到极大限制。
另外， 目前诸多无极灯的技术方案基本上从灯管的结构、 磁环的屏蔽和散热等入手， 而没有从无极灯与现有的灯具方便（面）配套去入手， 当使用者想把原有的灯更换成无极 灯的时候，却由于灯罩的反射器与灯泡的配光之间配套不吻合，从而造成照度不均或同时 更换一整套灯具，因此又带来资源浪费等不利因素，使无极灯在的应用范围受到了很大的 限制；这就需要一种能够在不更换原有灯具的同时又很方便自如的调节配光的无极灯，使 得既不浪费原有的灯具， 又能达到配光均匀， 且更换安装又容易， 来满足市场的需要。 发明内容
本发明所要解决的技术问題在于给出一种既能解决无极灯高温的导热及散热 (保障磁 体温度在安全范围内）， 也可将无极灯安装在密闭灯具中的散热的无极荧光灯。

所述的 T型支架的直挡部分和灯螺的下部为中空结构， 以方便引线。
由于采用以上的技术方案， 本发明具有以下的有益效果-
1、 抱箍底座采用导热平面可直接与灯具连接， 使整个灯具或灯罩成为耦合器的散热 装置。 在导热平面上增加 U型槽或 V型槽， 可以进一步增加导热面积。
2、 由于采用了该气体的配比， 更加简略了玻璃灯管的结构， 也减少了接桥和封接的 工艺， 解决了无极灯（无极荧光灯）在大功率回路长、管径细的灯管启动困难的问题， 提 高了灯泡在低温下的可靠启动；并且能够长期使用在低温的恶劣环境中，使无极灯的应用 范围更加广阔。

7、 由于改变玻璃灯管的结构， 使外耦合无极荧光灯灯管的悍接更加简单， 减少了接 桥和封接的次数； 同样生产一个灯， 减少了时间， 增加了产量； 使无极灯的应用范围更加 广阔， 并拓宽了无极灯的销售市场。
8、 本发明采用中空的 T型支架和灯螺， 可以方便布线； 在 T型支架上设置有若干调 节孔， 能够方便地调节灯管位于灯罩内的位置，在灯具安装在不同高度场所时，可以不需 要定制灯罩或更换原有的灯罩，就能达到无眩光、照度分布均匀的目标，且在同样的照度 要求下无须增加更多灯具来弥补眩光， 从而达到更加节能的效果。 附图说明

参见图 9, 整个灯管由一个半弯的 " π "型的玻璃灯管 600和一个半弯的倒 " r -1 "型的玻璃灯管 700焊接而成，在玻璃灯管 600和 700的内管壁上附着有三基色荧光粉 2， 玻璃灯管 600的两端折弯成第一感应面 610和第二感应面 620， 在玻璃灯管 600内设 置有一排气玻璃管 650， 排气玻璃管 650同时用于放置銦网 660， 对应第一感应面 610和 第二感应面 620对应的焊接面是平面。玻璃灯管 700的两端折弯成第三感应面 710和第四 感应面 720， 在玻璃灯管 700内设置有一折弯玻璃管 750， 折弯玻璃管 750内放置有汞齐 760, 折弯玻璃管 750可以防止汞齐 760倒流， 第三感应面 710和第四感应面 720对应的 焊接面是平面。 为了保持灯长期在低温状态下工作时， 保持灯的足够功率，在折弯玻璃管 750的汞齐 760部位套有一保温套 761， 这样灯长期在低温状态下工作时功率就会稳定。
第一感应面 610和第三感应面 710直接焊接成第一感应体 810;第二感应面 620和第 四感应面 720直接焊接成第二感应体 820;在第一感应体 810和第二感应体 820上各安装 有功率耦合器 （图中未使出）。 第一感应体 810和第二感应体 820的外径小于发光体外径 的 10%〜60%， 是为了更方便安装无极灯的感应磁环。 参照图 10， 本发明的功率耦合器 900， 包括抱箍底座 903和抱箍上盖 906, 抱箍上盖 906和抱箍底座 903—端由箍紧螺丝 912连接， 另一端采用定向合页机构抱紧连接。定向 合页机构包括一设置于抱箍底座 903另一端上的合页开口槽 913和一设置于抱箍上盖 906 另一端的合页钩轴 911，合页钩轴 911可转动地镶嵌于合页开口槽 913内， 参看图 10， 当 锁抱箍的箍紧螺丝 912不慎脱落后，其中合页钩轴 911相对于合页开口槽 913的最大开启 角度 α为 30-80° ， 优选为 35-50° 。这样灯管 Α不会因此而掉落， 有效防止了安全隐患， 安装更加方便。
在抱箍底座 903上设置有一与灯具反射器 915连接的导热面 910和螺孔 909，用两个 上装螺丝 916穿过灯具反射器 915上的孔旋入螺孔 909中，即可将整个功率耦合器安装在 灯具反射器 915上。抱箍底座 903上的导热面 910为平面。为了进一步提高导热效果，在 导热面 910上开设有 1-50条 U型槽或 V型槽 （图中未示出）。

与励磁线圈 907 电连接的励磁线圈输出线 908延伸出抱箍底座 903， 与 100KHz〜 300KHZ高频电子镇流器的输出连接。 在无极灯工作时， 给励磁线圈 907通入高频电流， 在磁场的作用下激活荧光灯中的汞蒸汽， 使汞原子的外层电子获取能量而发出紫外光子， 它被涂在灯壁上的荧光粉吸收便发出可见光。 实施例 4
参见图 12,灯具包括灯螺 1001、 T型支架 1002、走线固定条 1003， 走线固定条 1003 固定在灯管 A的上方，走线固定条 1003的两端分别与两个功率耦合器 900的导热面导热 连接， 连接方式基本上与上面一样。 灯螺 1001的下部 1001a和 T型支架 1002的直挡部 分 1002b均为中空结构，以方便走线。 T型支架 1002的横挡部分 1002a通过连接螺丝 1004 固定在走线固定条 1003的中部， 在 T型支架 1002的直挡部分 1002b两侧对称设置有 2 至 6个调节孔 1005,灯螺 1001的下部 1001a上对称设置有一个调节固定孔 1006，用两个 紧固螺栓 1013穿过灯螺 1001下部 1001a上的调节固定孔 1006和 T型支架 1002的直挡 部分 1002b上的任意一个调节孔 1005， 即可使灯螺 1001的下部 1001a与 T型支架 1002 的直挡部分 1002b连接， 通过灯螺 1001上的调节固定孔 1006与 T型支架 1002上不同的 调节孔 1005配合即可方便的调节配光，无需再次更换灯具，大大减少了灯具安装的数量。
