Abstract:
electrodeless lamp is a light source in which the power required to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields.Two systems available noe—one, plasma lamps, based on the use of radio waves energizing a bulb filled with sulfur or metal halides, and the other is, fluorescent induction lamps, based upon conventional fluorescent lamp phosphors .. and the Magnetic induction lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube, or inserted inside the lamp. In external inductor lamps, high frequency energy, from the electronic ballast, is sent through wires, which are wrapped in a coil around the ferrite inductor, creating a powerful magnet.
