Abstract
The utility model relates to a discharging electrode of a ceramic metal halide lamp, which is provided with a niobium casing tube, a tungsten core rod, tungsten wire helix and molybdenum wire helix, wherein one end of the tungsten core rod is wound with the tungsten wire helix to be made into an electrode head inserted into a discharging cavity of the ceramic metal halide lamp. One part of the other end of the tungsten core rod is wound with the molybdenum wire helix and extends into thin ceramic tube diameters at both ends of the ceramic lamp; a 0.03 to 0.05 mm gap error exists between the tungsten core rod and the ceramic lamp. The other part of the other end of the tungsten core rod is inserted into the niobium tube. The utility model achieves the sealed purpose by staving.
Description
Affiliated technical field:
The utility model relates to the sparking electrode of the ceramic gold-halogen lamp of a kind of 70W to 200W, is applicable to the ceramic gold-halogen lamp of 70W to 200W.
Background technology:
The sparking electrode of present known ceramic gold-halogen lamp has two kinds of structures, and a kind of is that niobium bar, molybdenum rod and tungsten bar collimation are coaxial docking, and adopts laser welding method to make; Another kind of tungsten bar and the molybdenum rod of adopting inserts molybdenum rod in the niobium pin, and the niobium pin obtains niobium bar certain degree of depth of punching.Making sparking electrode with these two kinds of methods all has certain technical difficulty, and the metal of welding is subjected to the influence of different thermal coefficient of expansions, and weld strength is not enough.
Summary of the invention
For the difficulty and the not enough problem of weld strength that overcome molybdenum tungsten and the butt welding of molybdenum rod niobium, the utility model provides the most easy method to make the sparking electrode of 70W to 200W ceramic gold-halogen lamp.Do not adopt the method for laser welding or niobium bar punching, but according to the internal diameter and the tungsten core diameter d of ceramic gold-halogen lamp two ends potteries tubule, the niobium sleeve that matches for sparking electrode processing specially cuts into the length of needs again.One end of this pipe inserts tungsten electrode, and the other end flattens sealing, becomes as a whole sparking electrode.
The coupling of the outer surface diameter of the molybdenum filament spiral on the sparking electrode and the two ends of ceramic gold-halogen lamp pottery tubule can be according to different lamp power designs, but will guarantee that gap error scope that external and internal compositions exists is at 0.03～0.05mm.The beneficial effects of the utility model are not have pad on this electrode, and are easy to process, improved intensity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural map of the utility model ceramic gold-halogen lamp discharging electrode.
Fig. 2 is the sectional structural map after the utility model electrode is put into ceramic metal halide lamp shell.
1. sparking electrodes among the figure, 2. Ceramic Balls cell-shell, the 3. tubule at Ceramic Balls cell-shell two ends, 4. the niobium pipe that does not flatten, 5. flattening sealing niobium pipe, 6. tungsten rod, 7. tungsten filament helix electrode tip, 8. molybdenum filament single-screw, 9. glass ring.
Embodiment
According to the ceramic gold-halogen lamp of different capacity 70w, 150w, 200w design electrode, by length and the length that internal diameter is determined sparking electrode (1), the outer dia of molybdenum filament single-screw (8) and the length of niobium pipe (4) of the tubule (3) at Ceramic Balls cell-shell two ends.Tungsten rod (6) is inserted in not the internal diameter external diameter of the diameter of length, the tungsten rod (6) of the niobium pipe (4) that flattens, the niobium pipe (4) that do not flatten and its flattening length sees Table 1.Tungsten filament helix electrode tip (7) is gone up by tungsten rod (6) and is made around a few circle tungsten filaments, determines the degree of depth of being inserted in of niobium pipe (4) according to different capacity, but firmness and sealing by fusing length when wanting to guarantee glass ring (10) sealing.After tungsten rod (6) being inserted the niobium pipe (4) that does not flatten remaining part is flattened into flattening sealing niobium pipe (5).
The data list of table 1 sparking electrode of the present utility model and ceramic gold-halogen lamp coupling
Claims (4)
1. ceramic metal halogen lamp pole, tungsten rod inserts the niobium pipe box and connects, and it is characterized in that: an end of tungsten rod is the tungsten filament helix electrode tip and twines the molybdenum filament spiral outward that the other end is tungsten rod and the socket of niobium pipe tight fit, and flattening seals.
2. ceramic metal halogen lamp pole according to claim 1 is characterized in that: tungsten rod cooperates H7/h6 with the utilization of niobium pipe.
3. ceramic metal halogen lamp pole according to claim 1 is characterized in that: the length that tungsten rod is inserted in the niobium pipe is decided according to different capacity, and the insertion depth of 70W, 150W and 200W is respectively 7mm, 8mm, 9mm.
4. ceramic metal halogen lamp pole according to claim 1 is characterized in that: the space error of the internal diameter of the ceramic tubule at the outer dia of molybdenum filament spiral and ceramic gold-halogen lamp two ends is 0.03～0.05mm.
