Abstract
The utility model relates to a conductive support frame for an electric arc tube lamp filament of a sodium lamp, which comprises a cylindrical tube body; one end of the tube body is opened, and the other end of the tube body is closed by a tube end which is integrated with the tube body into a whole; and a blind hole is formed on the tube end. In the utility model, because the blind hole is formed on the tube end, one end of the lamp filament (a tungsten electrode) is directly inserted in the blind hole; and the tungsten electrode is directly connected with an external power source through the conductive support frame so as to eliminate a structure that the tungsten electrode is welded with the conductive support frame through a niobium filament and titanium. Therefore, the utility model has the advantages of simple structure and simple manufacturing process and can effectively reduce the manufacturing cost.
Description
(1) technical field: the utility model relates to high-pressure sodium lamp, relates in particular to the parts of electric arc tube in the high-pressure sodium lamp.
(2) background technology: sodium vapor lamp belongs to the gas discharge illuminating source.It comprises be tightly connected lamp holder and glass bulb, wick is installed in the lamp holder, two inner guide wires of device in the wick, one end of two inner guide wires connects two electrodes of lamp holder respectively, the other end is connected with the top electrode and the following utmost point of sodium lamp arc tube respectively, and wherein an inner guide wire is connected with the top electrode of electric arc tube by the master metal support that is arranged in glass bulb.In glass bulb, vacuumize or be filled with inert gas,, improve luminous efficiency with oxidation that prevents metal parts in the glass bulb and the thermal loss that reduces electric arc tube.
Electric arc tube is a critical component in the said structure.Electric arc tube comprises the aluminium oxide ceramics body, the sealed at both ends connection filament of body conducting bracket, two conducting brackets externally connect external power, internally connect bottom electrode and top electrode respectively, described bottom electrode and top electrode are called filament again, helically shaped with the tungsten filament material, wherein store alkaline earth oxide, when filament adstante febre alkaline-earth metal emitting electrons.Be filled with mercury and mercury in the electric arc tube body and receive agent, and inert gas, high-pressure mercury vapor can be produced.Under the effect of two electrodes (filament) voltage, ionized inert gas disruptive discharge, the mercury vapour discharge, high light meanwhile takes place in the gaseous state of receiving discharge.
In the prior art (for example notification number CN2256166Y patent), the filament conducting bracket niobium alloy material of the sealed at both ends connection of electric arc tube body, described conducting bracket comprise one with the body of electric arc tube body soldering and sealing, body one end opens wide, the other end is the thin-walled sealing end, constitutes a niobium alloy cup, thin-walled sealing end perforate (or not perforate), with niobium silk and titanium and aperture (or thin-walled sealing end) welding, the other end of niobium silk and tungsten filament electrode welding.The conducting bracket of said structure will weld conducting bracket and tungsten filament electrode by niobium silk and titanium, complex structure, and manufacture craft is loaded down with trivial details.
The applicant is at the shortcoming of the conducting bracket of said structure sodium lamp arc tube filament, improve research, the conducting bracket of another kind of sodium lamp arc tube filament is provided, it does not need to weld niobium cup and tungsten filament electrode by niobium silk and titanium, simple in structure, manufacture craft is easy.
The technical solution of the utility model is as follows:
The conducting bracket of sodium lamp arc tube filament, comprise a drum body, described body one end opens wide, the other end by with body be the pipe end sealing of one, the conducting bracket of sodium lamp arc tube filament comprises a drum body, and described body one end opens wide, the other end by with body be the pipe end sealing of one, have blind hole on the pipe end.
In the utility model, on pipe end, have blind hole, one end of filament (tungsten filament electrode) directly inserts in this blind hole, tungsten filament electrode directly is connected with external power by conducting bracket, and omitted tungsten filament electrode by niobium silk and titanium and conducting bracket welded structure, simple in structure, manufacture craft is easy, can effectively reduce manufacturing cost.
Description of drawings:
Fig. 1 is a structure cutaway view of the present utility model;
Embodiment:
See Fig. 1, the utility model comprises the body 1 of drum, and an end of body 1 opens wide, the other end by with body 1 be that the pipe end 2 of one seals, have blind hole 3 on the pipe end.
The utility model is made of the niobium zirconium alloy material.Adopt the niobium zirconium alloy bar, become Fig. 1 shape by the mold cold extrusion process.During installation, in blind hole of the present utility model, insert an end of tungsten filament electrode respectively, adopt mechanical presses to clamp or adopt spot welding to connect tungsten filament electrode firmly is connected with blind hole.The above-mentioned the utility model that has connected tungsten filament electrode that is tightly connected respectively at the two ends of sodium lamp arc tube then, tungsten filament electrode is sealed in the electric arc tube, and the part of body 1 of the present utility model exposes outside the termination of electric arc tube.The described termination inner guide wire direct and in the sodium vapor lamp wick that exposes outside electric arc tube in lower end is connected, and the described termination that exposes outside electric arc tube, upper end is connected with another root inner guide wire of sodium vapor lamp wick by the master metal support that is arranged in the sodium vapor lamp glass bulb.Above-mentioned two inner guide wires are connected with two external power connection electrode of lamp holder respectively, so finish the installation of the utility model and electric arc tube.
Claims (2)
1. the conducting bracket of sodium lamp arc tube filament comprises a drum body, and described body one end opens wide, the other end by with body be the pipe end sealing of one, it is characterized in that having on the pipe end blind hole.
2. by the conducting bracket of the described sodium lamp arc tube filament of claim 1, it is characterized in that described conducting bracket is made of niobium zirconium alloy.
