Abstract
The invention relates to an electrodeless lamp modulator tube and a manufacturing method of the electrodeless lamp modulator tube. The electrodeless lamp modulator tube comprises a modulator tube body, a butt joint tube, a coupler and a cold end, wherein the butt join tube is connected with the modulator tube body in a butt joint mode to form a modulator tube closed circuit capable of storing inertia gas, the coupler is arranged outside the butt joint tube in a sleeved mode, and the cold end is formed on the butt joint tube and covered with the coupler. The position of the cold end on the conventional electrodeless lamp modulator tube is arranged in an area covered with the coupler, and therefore the temperature of the cold end is increased through the heat preservation effect of the coupler which surrounds the cold end, the temperature of the cold end is higher than the temperature of the surface of the whole modulator tube, and in other words, the effect of being free of the cold end is achieved; accordingly, the whole light source efficiency is improved, and the longer service life is obtained.
