หลอดไฟที่ไม่มีการคายประจุความถี่สูง (CZFN50W-165W)

High frequency electrodeless discharge lamp, HFED for short, is an up-to-date high tech product integrated with applied optics, power electronics, plasma study, magnetic material study and the like disciplines. As a new type light source reqresenting 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 environmental protection ligh source in the 21st century.

The HFED consists of bulb, power coupler and electronic ballast, which is also known as the power source. The power coupler is built inside the bulb, connecting the electronic ballast through feeder line. The coupler induces and couples high-frequency electromagnetic energy created by the generator into the bulb, which makes the air inside the bulb cumulatively ionized into plasma. Excited atom of the plasma while returning to ground state will spontaneously radiate ultraviolet light that will inwigorate the phosphor powder on inner wall of the bulb to give off visible light.
