Abstract
This utility model relates to a high pressure halogen lamp, which belongs to the field of halogen lamp technology, aims to resolve following technical problems: prevention of explosion led by short-circuit resulted from breakdown of the filament, elimination of factors that may affect normal halogen circulation in the glass casing, and prolonging of service life of the filament. Therefore, a glass column is arranged in the center of the casing, of which the top is fixedly connected with the top of the casing and the lower end is fixedly connected with the upper end of the sealed part of the casing. A horizontal through hole is provided at the upper part of the glass column, through which the filament goes and then connects with an electrode molybdenum sheet on both ends.
Description
Technical field
The utility model relates to the Halogen lamp LED technical field, particularly a kind of high-pressure halogen lamp.
Background technology
Existing high-pressure halogen lamp is made up of glass bulb, bead, electrode pin, connection molybdenum sheet, metal supporting frames, filament, be encapsulated in the glass bulb bottom on the electrode pin with after molybdenum sheet is connected, the metal supporting frames that filament is formed by several Metallic rod supports, bead is used for fixing the foot of contact conductor and metal supporting frames, the shape that filament is maintained fixed.Can there be following weak point in said structure:
(1) when filament is died of old age or be subjected to external impacts, filament breakage might drop into and cause short circuit between two electrode supporting bars of metal supporting frames and set off an explosion.
(2) because the metal supporting frames chemical stability is bad, impurity is difficult for cleaning, and when lighting a lamp, in the halogen gas in pervaporation is mingled in cell-shell, thereby influences normal halogen cycle, shortens the useful life of filament.
Summary of the invention
The technical problems to be solved in the utility model is: (1) prevents the blast that causes short circuit to cause because of filament breakage; (2) remove factor influence normal halogen cycle in the glass bulb, raising filament useful life.
The technical solution that the utility model proposed is such: a kind of high-pressure halogen lamp, comprise glass bulb, electrode pin, connection molybdenum sheet, filament, be encapsulated in the glass bulb bottom on the electrode pin with after molybdenum sheet is connected, central authorities erect and put a glass pillar in glass bulb, fixedly connected with the glass bulb top in its top, fixedly connected with described glass bulb encapsulation upper end in its lower end, described glass pillar middle and upper part is provided with cross through hole, and its two ends were connected with electrode molybdenum slice respectively after filament penetrated this cross-drilled hole.Between described glass pillar bottom and the glass bulb encapsulation metal reinforcing is housed.Described filament two ends and corresponding electrode molybdenum sheet connecting portion clamp are in the glass bulb encapsulation.
Compared with prior art, the utlity model has following beneficial effect:
(1) owing to no longer be provided with two electrode metal support bars and Multi-filament metallic support rod in the glass bulb, promptly cancels metal supporting frames, when filament is died of old age or is subjected to external impacts and the Shi Buhui that falls of breaking causes two electric pole short circuits, thereby avoided the generation of fried lamp.
(2) owing to do not have any exposed metal object basically in the glass bulb except that filament, the glass supporter that replaces has good chemical stability, easily cleans impurity, can not influence the normal halogen cycle of filament, thus the useful life of having improved filament.
Description of drawings
Fig. 1 is the high-pressure halogen lamp structural representation of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Embodiment
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, the high-pressure halogen lamp of present embodiment is made up of glass bulb 2, two electrode pins 7, two plate electrode molybdenum sheets 6, filament 3 and glass pillars 1.The glass pillar is fixedlyed connected with the top and the encapsulation 5 thereof of glass bulb 2 respectively at two ends about in the of 1, and this glass pillar 1 middle and upper part is provided with a cross through hole, is used to pass filament 3 and play supporting role.Filament 3 two ends are connected with corresponding electrode molybdenum slice 6 by molybdenum filament, its connecting portion basically by clamp in encapsulation 5, thereby except that filament, do not have any exposed metal object basically in the glass bulb.Draw glass bulb 2 outsides after two electrode pins 7 and corresponding electrode molybdenum slice 6 welding.For the rigidity of reinforced glass pillar 1, prevent to be provided with metal reinforcing 4 between middle and lower part in glass pillar 1 and the encapsulation 5 because of brittle failure may take place external impacts.
Claims (3)
1, a kind of high-pressure halogen lamp, comprise glass bulb, electrode pin, connection molybdenum sheet, filament, be encapsulated in the glass bulb bottom on the electrode pin with after molybdenum sheet is connected, it is characterized in that: central authorities erect and put a glass pillar in glass bulb, fixedly connected with the glass bulb top in its top, fixedly connected with described glass bulb encapsulation upper end in its lower end, described glass pillar middle and upper part is provided with cross through hole, and its two ends were connected with electrode molybdenum slice respectively after filament penetrated this cross-drilled hole.
2, high-pressure halogen lamp according to claim 1 is characterized in that: between described glass pillar bottom and the glass bulb encapsulation metal reinforcing is housed.
3, high-pressure halogen lamp according to claim 1 is characterized in that: described filament two ends and corresponding electrode molybdenum sheet connecting portion clamp are in the glass bulb encapsulation.
