Abstract

The invention relates to a low-pressure mercury vapor discharge UV (ultraviolet) germicidal lamp, and in particular relates to a high-power externally-coupled electrodeless UV lamp. The UV lamp comprises a closed lamp tube with an annular section, a coupler, and a high-frequency driver, and is characterized in that the high-frequency driver has the self-adaption characteristic, the diameter of the closed lamp tube is 46mm-56mm, the inner capacity of the closed lamp tube is 780cm<3>-2100cm<3>, inert gases with a pressure being 0.09-0.2 Torr and mercury vapors are filled in the closed lamp tube, and the mercury amount in the closed lamp tube is 16mg to 35mg; and the coupler comprises a first coupler unit and a second coupler unit, the first coupler unit and the second coupler unit are closed magnetic ring coupler units wound with coils, the total inductance amount of the coils of the closed magnetic ring coupler units is controlled about 0.45mH, and the first coupler unit and the second coupler unit are communicated with the high-frequency driver.

Description

technical field [0001] The invention relates to a low-pressure mercury vapor discharge ultraviolet germicidal lamp, in particular to a high-power externally coupled electrodeless ultraviolet lamp. Background technique [0002] The electrode ultraviolet lamp in the prior art has a short service life (the national standard GB 19258-2003 stipulates that the average service life is not less than 5000 hours), and the power is not large, mainly due to the limitation of the length of the lamp tube. Taking the 40W UV lamp as an example, its length is 120cm. If the power is increased, the length will need to be increased, and the ignition voltage and working voltage will need to be increased accordingly, thus limiting the random increase in the length of the lamp tube. So it is impossible to increase the power a lot on the basis of 40W. The current single-ended UV lamp with a filament has a maximum power of 55W listed in the national standard, and the power cannot be increased, resu...
