The underground lamp has the characteristics: 1. Long life, low light failure. 3. Environment protection. 3.No blinking
The light source of the underground lamp is electrodeless induction 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 lighting 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 century. High-frequency electrodeless discharge lamp is made up of the light bulb, power coupler and electrodeless lamp electronic ballast (commonly known as power). Coupler is installed in the light bulb, and connected to electrodeless lamp electronic ballast throgh high-frequency connection wires, induces and 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 returns into ground state, it radiates ultra-violet light to excite fluorescent powder over the inner wall of the bulb to generate visible light.
