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.
結構及原理
高頻等離子體放電無極燈由燈泡、功率耦合器和高頻發生器（俗稱電源）三部分組成。耦合器裝于燈泡內，通過饋線與高頻發生器連接，將高頻發生器所產生的高頻電磁能感應耦合到燈泡內，使燈泡內的氣體雪崩電離形成離子體。等離子體受激原子返回基態時自發輻射出紫外光，激發燈泡內壁的熒光粉而使之發出可見光。
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.
產品特點---------Features of HFED
1．超長壽命(Super long service life):
燈內無燈絲和電極，燈泡壽命僅取決于熒光粉的自然衰減，它是所有光源中壽命最長的一種光源。設計壽命指標≥6萬小時（正常使用約10年），其壽命是白織燈的50倍，金鹵燈的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．高效節能(High-efficiency&Energy-saving):
發光效率高，節能效果好。光效≥70lm/w，是白織燈的5倍，與普通白織燈相比，可節能80％以上。
High luminous efficiency and excellent energy saving. The opticiency ≥ 70lm/w,5 times th- at of ordinary incandescent lamp . Can save energy more than 80%.
3．綠色環保(Envionmenttal Protection):
無閃爍、無濺射、低眩光、徹底消除眼睛疲勞，且不含液態汞。是綠色環保的首選光源。
Freedom from filcker, no spluttering and low glare. Can thoroughly eliminate eye fatigue. Free of liquid mercury,it is the best light source for environmental protection.
4．顯色性好(Excellent color Rendering):
顯色指數≥80,非常接近於自然光，照明舒適;色溫可選，可實現各類使用環境所需要的不同光色照明。
Color rendering index ≥ 80, extremely close natural light. Comfortable lighting,Multiple choices of color temperature. Can realize lighting with different color in different environm- ent.
5．瞬間啟動(Excellent color rendering):
啟動時間≤0.5秒，無需預熱，瞬間可啟動照明。
Stating time ≤ 0.5 second.Nos needed ,instant startup.
