Description

Lamp filament structure of excimer lamp tube

Technical Field

The utility model relates to the field of lamp tube coating or printing structures, in particular to a lamp filament structure of an excimer lamp tube.

Background

Excimer UV lamps are the latest technological achievement today and emit UV light at a specific wavelength. Because the output energy is concentrated and the output intensity is high, the deactivation of viruses, bacteria and microorganisms can be carried out according to different nanometer wavelengths, and urban sewage and air purification and photochemical reaction can be carried out, so that the nano-composite material is used for synthesizing new nano-materials and the like.

In the high-power excimer UV lamp tube on the current market, an outer filament is wound on the surface of a circular lamp tube by adopting a metal wire with the thickness of about 0.1mm, and a long metal circular tube is directly inserted into the inner wall of an inner circular tube in a double-layer circular tube to replace the inner filament. Under specific high voltage, the metal electrode in the excimer lamp tube and the electrode on the outer surface of the lamp tube enter into discharge arc, the discharge arc is triggered to directly penetrate through the middle inner vacuum part of the double-circular tube, and inert gases such as krypton chloride and the like in the vacuum tube are triggered to emit ultraviolet light for output.

The conventional manner of using wire-wrapping has the following drawbacks. Firstly, because there are the clearance in the inside surface metal of fluorescent tube and outside surface metal parts and the quartz lamp table, there is a large amount of air in these clearances, discharges between the electrode when fluorescent tube work and draws the arc and can make the air produce ionization phenomenon to produce a large amount of ozone. When the ozone content in the space reaches a certain standard, people can not adapt to the ozone, and the ultra-short wavelength ultraviolet light can be blocked by the ozone, so that the ultraviolet light transmission energy is greatly reduced. Secondly, the metal surface is wound with the filament, the expansion coefficients of the metal filament and the glass of the lamp tube are greatly different, the metal filament can be seriously deformed in a cold and hot state, the filament is wound on the surface of the lamp tube and is inclined from east to west, an uneven state is caused, the power of the lamp tube is influenced, and the luminous efficiency is influenced. Thirdly, the surface metal wire is difficult to wind on the surface of the quartz glass and is fixed, a copper sheet with the width of 10mm is usually adopted to be adhered on the surface of the quartz glass, then the filament is wound, and finally the filament is welded on the copper sheet; or the two ends of the lamp tube are sleeved on the lamp tube by steel disc ring sheets and then fixed by screws. Both of these methods are very labor and material intensive and are not suitable for mass production.
