摘要
The present utility model relates to the technical field of lighting, in particular, to a high-intensity, closed in two tubes explosion-protected high-pressure gas discharge lamp, which contains a plurality of light source tubes, a quartz tube of the inner layer and a quartz tube of the outer layer. Light source tubes are installed in the quartz tube of the inner layer, the quartz tube of the outer layer is worn externally on the quartz tube of the inner layer; and the two ends of the quartz tube of the outer layer are welded and sealed on the quartz tube of the inner layer through an annular bend. The advantages of this utility model are as follows. Due to the fact that a quartz tube of the outer layer with two sealed ends is added outside the outer wall of the quartz tube of the inner layer, fragments of the quartz tube of the inner layer created by the explosion of the tubes of the light source will remain inside the quartz tube of the outer layer, so the present utility model is more secure. leakage of metal halide outward is prevented, thereby protecting the external environment. In addition, the evaporation of mercury in the tube can be effectively prevented in such a way as to prevent danger to the human body.
