Abstract
The invention discloses an UV bulb structure of a metal halide lamp and a manufacturing method thereof. The UV bulb structure of the metal halide lamp comprises a glass shell and an emitter component, wherein working gas exists between the glass shell and the emitter component, and no mercury exists in the glass shell chamber. Since the UV bulb structure is of a mercury-free design, has no radioactivity, and is environmental-friendly, the risk of blasting due to high internal pressure of the mercury vapor does not exist. The working gas between the emitter component and the glass shell can emit visible radiation or ultraviolet radiation to illuminate a discharge tube, thereby effectively facilitating switching on the metal halide lamp.

The invention still further relates to the manufacture method of the UV bubble structure of above-mentioned metal halide lamp.
Background technology
The high intensity discharge metal halide lamp more and more is widely used, but because halogen atom and halid existence cause Metal halogen lamp to start into difficult problem, product started in order to help in the past, added radioactive substance, and environment is caused very big pollution.Having invented a kind of mercurous UV bubble afterwards helps to start, because mercury vapour, argon gas gaseous mixture in the UV bubble under high pressure can produce the electric arc tube startup that ultraviolet ray (UV) helps metal halide, therefore this UV bubble structure effect is fine, but the introducing of mercury has increased production cost contaminated environment again.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of no mercury UV bubble structure of metal halide lamp, can reduce environmental pollution when helping Metal halogen lamp to start.
The present invention is by the following technical solutions:
A kind of UV bubble structure of metal halide lamp comprises between glass shell, emitter assembly, described glass shell and the emitter assembly that working gas is arranged, and is not mercurous in the cavity of described glass shell.
Further, the diameter range of the middle part cylinder of described glass shell is 2.0mm～10.0mm.
Preferably, the diameter range of the middle part cylinder of described glass shell is 3.0mm～5.0mm.
Further, described emitter assembly comprises molybdenum sheet and molybdenum rod, and described molybdenum sheet is sealed in the glass shell, and the lead-out wire molybdenum rod stretches out from glass shell one end.
Further, described emitter assembly comprises Dumet wire and lead-out wire, and described Dumet wire is sealed in the glass shell, and lead-out wire stretches out from glass shell one end.
Further, described glass shell two ends are integrated clamp plank.
Further, molybdenum rod is connected with an electrode outlet line of metal halide lamp.
Preferably, metal halide lamp has two electrodes, and another electrode connects quoit, and this quoit is looped around on the glass shell.
Because the present invention does not have radioactivity for no mercury design, therefore very environmental protection does not exist at high temperature because of producing the risk of the too high explosion of mercury vapour internal pressure.Working gas between emitter assembly and glass shell can send visible radiation or ultra-violet radiation irradiation discharge tube, effectively helps Metal halogen lamp to start.
Another technical problem that the present invention will solve provides a kind of manufacture method of UV bubble structure of described metal halide lamp, can simplify production process, enhances productivity.
The present invention is by the following technical solutions:
A kind of manufacture method of UV bubble structure of metal halide lamp, described UV bubble structure comprises envelope of quartz glass and molybdenum sheet assembly, may further comprise the steps:
(1) described molybdenum sheet assembly is inserted an end of the quartz glass of not moulding;
(2) there is an end of molybdenum sheet assembly to heat to quartz glass, simultaneously to the logical argon gas of the quartz glass other end;
(3) treat that quartz glass is softening, to the fire end clamping, make envelope of quartz glass one-body molded, the shell two ends are one-time formed clamp plank;
(4) envelope of quartz glass of moulding is separated with moulding quartz glass not.
Perhaps also can adopt another kind of technical scheme:
A kind of manufacture method of UV bubble structure of metal halide lamp, described UV bubble structure comprise glass shell and Dumet wire assembly or other metal assembly, may further comprise the steps:
(1) described Dumet wire assembly is inserted an end of the glass tube of not moulding;
(2) there is an end of Dumet wire to heat to glass tube;
(3) make glass sintering fusing and sealing Dumet wire;
(4) to after inserting working gas in the single head sealing semi-finished product, the duration and degree of heating sintering sealing other end.
Because not mercurous in the UV bubble structure, and working gas content is few, can reduce the environmental pollution that causes in the production process.In addition, because the no mercury of this UV bubble is compared mercurous UV bubble, production technology is more simple and convenient, reduces production process, has improved production efficiency and constant product quality.
