Preferably, described shell nozzle place establishes lead-out wire, and an end of lead-out wire is located in the housing, and the other end is located at outside the housing, and described lead-out wire is connected with housing seal by glass solder.
Preferably, described shell nozzle place establishes stopper, and described stopper one end inserts in the housing, is tightly connected by glass solder between stopper and the housing.
Preferably, described lead-out wire is metal or cermet material.
Preferably, described stopper is ceramic material or cermet material.
Preferably, described glass solder is for to fire the material that forms by the rare earth metal oxide.
The invention has the beneficial effects as follows: the polycrystal alumina transparent ceramic material with high ultraviolet permeability is as container, and the housing of preparation UV generator.Because ceramic material can not produce the softening transform problem, the inner no Kr85 gas of Metal halogen lamp, "dead", and can obtain the sufficient intensity ultra-violet radiation, compact conformation provides more flexibility can for the design of high-intensity gas discharge lamp.
Another technical problem that the present invention will solve provides the manufacture craft of above-mentioned UV generator.
The present invention is by the following technical solutions:
A kind of manufacture craft of UV generator, comprise the housing moulding, described housing is the polycrystal alumina transparent ceramic material, the place puts into lead-out wire at shell nozzle, one end of this lead-out wire inserts in the housing, the other end outside housing, between described lead-out wire and the housing by glass solder with Hg in the housing (mercury) and inert gas seal.
Perhaps adopt another kind of technical scheme: a kind of manufacture craft of UV generator, comprise the housing moulding, described housing is the polycrystal alumina transparent ceramic material, the place puts into stopper at shell nozzle, stopper one end inserts in the housing, between described stopper and the housing by glass solder with Hg in the housing (mercury) and inert gas seal.
The invention has the beneficial effects as follows: because the polycrystal alumina transparent ceramic material of the high ultraviolet permeability of employing is as housing.This material has low preparation temperature and short production cycle, and control easily on size and structure.And, make technology simple with glass solder mode sealing-in ceramic shell.This technology is fit to large-scale production, and qualification rate is expensive cheap.
