PLASMA LIGHTING SYSTEM

摘要

PURPOSE: An electrode-less lighting system is provided to change oscillation frequencies by changing the shape of a vane and determining distance between the vane and a strap and to reduce installation space. CONSTITUTION: A waveguide(400) is communicated with a magnetron. A electrode-less bulb(600) is filled with a luminescent material. The electrode-less bulb emits light according to super high frequencies. A light sensing unit senses the light emitted from the electrode-less bulb. A resonator(500) accepts the electrode-less bulb and is connected to the waveguide. A resonator is formed into a mesh shape. A power supply unit changes commercial power into a driving voltage and a filament current. The power supply unit applies the driving voltage and the filament current to the magnetron.
