Abstract
The utility model discloses a niobium cup for high-voltage sodium lamps, which relates to a lamp, particularly an irregular cup body for the high-voltage sodium lamps. The utility model is characterized in that the outer end of the irregular cup body is provided with a circumferential flange; the bottom of the irregular cup body is provided with a concave groove. The utility model has the advantages of simple structure, easy manufacturing, low cost, high yield, etc., eliminates the possibility of sodium leakage at high temperatures fundamentally, and increases the service life of sodium lamps.
Description
The utility model relates to a kind of light fixture, refers in particular to the special-shaped cup that a kind of high-pressure sodium light fixture is used.
High-pressure sodium lamp is as electric light source of new generation, because of its long service life, energy savings, advantage such as light is soft is widely used day by day, but sodium at high temperature corrosivity is very strong, therefore, the niobium alloy pipe that adopts high temperature corrosion-resisting all is that tungsten electrode is inserted in the niobium pipe as the connector of deciding tungsten electrode, mode with mechanical grip or weldering knot is connected as a single entity again, yet all has defectives such as processing cost height, rate of finished products are low.
The purpose of this utility model is to overcome above-mentioned not part of the prior art, and provide a kind of both simply, save material and improved the special-shaped niobium alloy cup in sodium vapor lamp useful life.
The utility model is achieved by the following scheme: there is a flange around garden week at the place, outer end of the special-shaped cup of cup-shaped, and there is a recessed groove at the cup end.
The utlity model has following advantage:
1, adopts cheap niobium plate by punch forming or rotary press modelling or other processing method, be processed into special-shaped ring body, reduced much than the existing niobium alloy pipe processing cost that is adopted;
2, the union end shutoff of an end of special-shaped ring body and tungsten filament has fundamentally been stopped at high temperature to leak the possibility of sodium, thereby has been improved the useful life of sodium vapor lamp;
3, the recessed end of special-shaped cup inserts tungsten electrode with mechanical means clamping or electron beam welding, has saved and has added the loaded down with trivial details operation that the titanium wire bond connects, and saves artificial, the consumption of material resources, eliminated the waste product that causes because of the melt titanium silk, rate of finished products can reach 100%, thereby greatly reduces the cost of sodium vapor lamp;
4, there is a flange special-shaped cup outer end, can block the ceramics that the shutoff porcelain tube is used, and can reduce used cold folder technology, is convenient to assembling.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is the utility model structural representation
See accompanying drawing, special-shaped cup 1 forms the garden post cup of flange 13 by punching press or other processing method, diameter is D, and the recessed length in other end cup bottom is L1, and diameter is the groove 12 of d and do, its wall thickness equates with the cup wall thickness or is thicker that d equates with the insertion electrode size or be big slightly.
The concrete processing method of special-shaped cup 1 is: the method that adopts niobium plate punch forming or spinning, be worked into desired size: be specially D=1.5-10mm, D1=D+0.5-1mm, t=0.1-1mm, t1=2t, L=10-50mm, L1=1-5mm, L2=0.2-0.5L, do=d+0.3-0.7mm or d=do, d are equal to or slightly greater than the size of inserting electrode.When tungsten electrode is inserted in the d hole, adopt mechanical grip or spot welding, can realize that special-shaped cup is connected reliably with tungsten electrode.
Claims (3)
1, the niobium cup on a kind of high-pressure sodium lamp is characterized in that: there is a flange D1 at the L2 place, outer end of special-shaped cup D, and there is a recessed long L1 at the cup end, and internal diameter is the groove of d and do.
2, the niobium cup on a kind of high-pressure sodium lamp according to claim 1 is characterized in that: D=15-10mm, D1=D+0.5-1mm, t=0.1-1mm, t1=2t, L=10-50mm, L1=1-5mm, L2=0.2-0.5L, d=do or do=d+0.3-0.7mm.
3, the niobium cup on a kind of high-pressure sodium lamp according to claim 1 is characterized in that: the tungsten electrode equal diameters of d and insertion or big slightly.
