Title:
PLASMA EMISSION DEVICE, AND ELECTROMAGNETIC WAVE GENERATOR EMPLOYED IN SAME
Document Type and Number:
WIPO Patent Application WO/2014/010226
Kind Code:
A1
Abstract:
Provided is a plasma emission device for enhanced emission efficiency, and improved total luminous flux based thereon. The plasma emission device (1) has: an electromagnetic wave generator (2); a waveguide (4) for transmitting electromagnetic waves radiated from the electromagnetic wave generator (2); an antenna (5) for receiving the electromagnetic waves transmitted through the waveguide (4); an electromagnetic wave focuser (6) irradiated by electromagnetic waves from the antenna (6); and an electrodeless valve (7) situated inside the electromagnetic wave focuser (6), and is designed to emit a plasma through excitation, by electromagnetic waves, of a light-emitting substance filling the interior of the electrodeless valve (7). In this plasma emission device (1), the electromagnetic wave generator (2) is provided with a cathode part and an anode part, and the maximum output efficiency of electromagnetic waves generated at an input power of 700 W or less is 70% or greater.
