The invention relates to a high-power microwave dual-spectrum ultraviolet lamp device, comprising a first cavity, a second cavity, a waveguide slot, a waveguide, a waveguide, an electrodeless ultraviolet lamp, an excitation cavity, a magnetron, and an excitation cavity. And magnetron 2, the first cavity is connected with a second cavity, the first cavity is connected with a waveguide 1 and a waveguide 2, and the waveguide 1 and the waveguide 2 are connected with an external experimental connection device excitation Cavity 1, magnetron 1, excitation cavity 2 and magnetron 2. The high-power microwave dual-spectrum ultraviolet lamp device is connected to the semi-elliptical cavity by two waveguides, and the microwave is fed into the cavity through the middle slit, and the microwave is fed simultaneously from the two waveguides, on the semi-elliptical cavity. The directions of the opened waveguide slots are different, resulting in different polarization directions of microwaves, which can achieve the effect of reducing mutual coupling, improve the utilization rate of energy, and achieve better uniformity of field distribution.
Description
Technical field[0001]The present invention relates to the technical field of microwave dual-spectrum ultraviolet lamps, in particular a large power microwave dual-spectrum ultraviolet lamp device.Background technique[0002]The microwave plasma non-extreme ultraviolet light source is a new generation of gas discharge light, which does not produce a black phenomenon caused by electrode oxidation, loss, and sealing problems like traditional light sources. The microwave plasma is formed of microwave discharge, has a high degree of ionization degree, electronic density, electron temperature, ion temperature and a wide range of operating pressure; microwave plasma ultraviolet lamps are taking microwave excitation plasma to illuminate, greatly reduced. Electrode pollution improves the service life. At the same time, the accepted light source also has the advantages of variable shape, fast start, stable luminescence, and high efficiency.[0003]At present, the development of plasma UV lamps at...
