无极灯 - 维基百科，自由的百科全书
无极灯 （Electrodeless lamp），也称 無電極燈 、 感应灯 （induction light），是一种没有 电极 和灯丝的照明设备，它通过灯管外的磁环产生 电磁波 激发灯管内的物质工作。 例如低压气体无极灯内充填的是 汞 蒸气和 稀有气体 的混合气体，汞原子被 电离 、激发后释放出 紫外线 照射到灯管壁的荧光物质上， 荧光物质 发出可见光。 虽然也填充了汞，但其固汞含量要低于 荧光灯。 [1] 其工作频率通常达到数百万赫兹，远高于普通的 白炽灯 和 节能灯。 由于省去了灯丝和电极，可 …
无极放电灯 - 百度百科
无极放电灯是由一个数厘米长、直径5-12厘米的 石英玻璃 圆管制成。 管内装入数 毫克 待测 元素 或 挥发性 盐类，如金属、金属氯化物或 碘化物 等，抽成 真空 并充入 压力 为67-200Pa的 惰性气体 氩或氖，制成 放电管，将此管装在一个 高频发生器 的 线圈 内，并装在一个 绝缘 的 外套 里，然后放在一个 微波发生器 的同步空腔 谐振器 中。 这种 灯 的 强度 比 空心阴极灯 大几个 数量级，没有 自吸， 谱线 更纯。
Induction lamp - Wikipedia
The induction lamp, electrodeless lamp, or electrodeless induction lamp is a gas-discharge lamp in which an electric or magnetic field transfers the power required to generate light from outside the lamp envelope to the gas inside.
Electrodeless Discharge - an overview | ScienceDirect Topics
An electrodeless discharge refers to a type of lamp that uses either microwave or radiofrequency energy to atomize and excite analyte atoms in a sealed tube containing an inert gas at low pressure. You might find these chapters and articles relevant to this topic.
