Introduction of Electrodeless Lamp
High frequency electrodeless discharge lamp, HFED for short, is an up-to-date high tech prod uct integrated with applied optics,power electronics, plasma study,magnetic material study and the like disciplines. As a new type light source representing future development trend,it is of high luminous efficacy, high color rendering property and long service life, destined to become the most promising energy-saving and environ mental-protection light source in the 21st century.
结构及原理
高频等离子体放电无极灯由灯泡、功率耦合器和高频发生器（俗称电源）三部分组成。耦合器装于灯泡内，通过馈线与高频发生器连接，将高频发生器所产生的高频电磁能感应耦合到灯泡内，使灯泡内的气体雪崩电离形成离子体。等离子体受激原子返回基态时自发辐射出紫外光，激发灯泡内壁的荧光粉而使之发出可见光。
Structure and Operating Principle of Electrodeless Lamp
The HFED comsists of bulb, power coupler and high-frequency generator. The power coupler is built inside the bulb, connecting the high-frequency generator through feeder line. The coupler induces and couples high-frequency electromagnetic energy created by the generator into the b-ulb, which makes the air inside the bulb cumulatively ionized into plasma. Excited atom of the plasma whlie returning to ground state will spontaneously radiate ultraviolet light that will invigorate the phosphor powder on inner wall of the bulb to give off visible light.
产品特点---------Features of HFED
1．超长寿命(Super long service life):
灯内无灯丝和电极，灯泡寿命仅取决于荧光粉的自然衰减，它是所有光源中寿命最长的一种光源。设计寿命指标≥6万小时（正常使用约10年），其寿命是白织灯的50倍，金卤灯的10倍。
No filament and electrode in the bulb, Service life of the bulb depends on natural attenua- tion of phosphor powder. It has the longest service life among all light sources. Designed ser- vice life≥60 thousand hours, 50 times that of incandesent lamp, and 10 times that of gold ha- log en lamp.
2．高效节能(High-efficiency&Energy-saving):
