Embodiment Construction

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Such as figure 1 As shown, in the electromagnetic shielding net of this embodiment, the electromagnetic shielding net 1 is provided with a plurality of mesh holes 11 of equilateral hexagonal structure, and the mesh holes 11 are arranged in a matrix. By arranging the mesh 11 of equilateral hexagonal structure, the utilization efficiency of microwave is greatly improved, and the utilization efficiency of microwave has reached more than 75%; The number of meshes inside has increased a lot, which greatly improves the light transmittance of the whole lamp, reduces the resonant interference frequency during the working process of the lamp, makes the frequency of the ultraviolet lamp more single, and improves the ov...

Abstract

The invention relates to an electromagnetic shielding mesh. A plurality of mesh holes of an equilateral hexagonal structure are formed in the electromagnetic shielding net. According to the invention,mesh holes of the equilateral hexagonal structure are arranged, so that the use efficiency of microwaves is greatly improved. The use efficiency of the microwaves reaches more than 75%. Meanwhile, due to the arrangement of mesh holes of the equilateral hexagonal structure, the number of mesh holes in the unit area of the electromagnetic shielding mesh is increased, so that the light transmittanceof a whole lamp is greatly improved. The resonance interference frequency in the working process of the lamp is reduced, so that the frequency of the ultraviolet lamp is more single. The light effectof the whole lamp is improved by more than 15%.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to an electromagnetic shielding net. Background technique [0002] Microwave electrodeless ultraviolet light source is a kind of ionization that excites the inert gas and luminescent substance in the quartz bulb in the high-energy microwave field to emit ultraviolet light. Its lamp tube has neither filament nor electrode, but is filled in a vacuum quartz tube. Add a small amount of glow gas and luminescent substance. The microwave resonant cavity plays a very critical role in the entire lamp. The structure of the electromagnetic shielding net has a great influence on the light efficiency and light transmittance of the resonant cavity, and even directly affects the service life of the lamp. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electromagnetic shielding net aiming at the deficiencies of the prior art. ...
