The lamp is high-frequency electrodeless lamp,referring to as High Frequency Electronic Discharge Light(HFED),is a high-tech product developed by applying comprehensively the latest achievements on optics,power electronic,plasma science,magnetic materials study etc,a new type of light source representing future development direction of lightiong technology in high luminous efficidency,long life and high color rendering property and a green energy-saving lighting source which is the most promising in the 21st centuryHigh-frequency electrodeless discharge lamps is made of the light bulb,power coupler and electrdeless lamp electronic ballast(commonly known as power)coupler is installed in the light bulb,and connected to electrodeless lamp electronic ballast through high-frequency connection wires,inducesand couples high-frequency electromagnetic energy generated by electrodeless lamp electronic ballast into the bulb,so that gas cumulative ionization in the bulb forms plasma.when stimulated atom of plasma retums into ground state,it radiates ultra-violet light to excite fluorescent powder over the  inner wall of the bulb to generate visible light

Explosion-proof lamp
