A method for manufacturing a mesh screen of an electrodeless lighting system, capable of intercepting microwave and passing light generated in a bulb, including a mesh screen forming step for forming a mesh screen to have a mesh structure, a first plating step for plating first metal substance on the surface of the mesh screen, a vacuum heat-treating step for vacuum-heat-treating the mesh screen under the condition that the temperature is risen to a predetermined degree, a second plating step for plating second metal substance on the surface of the mesh screen and a photocatalytic coating step for coating photocatalytic substance on the surface of the mesh screen, can improve plating characteristic of the mesh screen, strengthen the maintenance strength, lengthen the life span of the mesh screen and improve the optical character.
Description
technical field [0001] The present invention relates to an electrodeless lighting system using microwaves, and in particular to a method for fabricating a mesh screen of the electrodeless lighting system capable of blocking microwaves and passing light generated in bulbs. Background technique [0002] Electrodeless lighting system is a device for emitting visible light or ultraviolet light by making microwaves act on an electrodeless lamp, and thus has a longer life than commonly used incandescent and fluorescent lamps and has a higher luminous Effect. [0003] figure 1 is a longitudinal sectional view showing a conventional electrodeless lighting system according to the prior art. [0004] A conventional electrodeless lighting system includes a magnetron 1 for generating microwaves; a waveguide 3 for guiding the microwaves generated from the magnetron 1; The microwave energy transmitted through the waveguide 3 is plasma-polymerized to generate lig...
