Abstract
The utility model relates to an explosion-proof tungsten-halogen lamp which comprises a glass shell, a lamp holder and a sealing molybdenum sheet. The glass shell is further arranged inside with a glass bead, an electrode supporter rod, a filament supporter rod and a filament. The glass bead is provided with an auxiliary rod connected with the sealing molybdenum sheet. The electrode supporter rod is connected with the auxiliary rod by a metal wire. The electrode supporter rod, metal wire and auxiliary rod are electrically connected to each other. The utility model imparts the explosion-proof property to the common tungsten-halogen lamp without needing additional fuse. The utility model has advantages of compact structure, convenient use and easy production.
Description
Technical field
The utility model relates to a kind of tungsten halogen lamp, especially has the tungsten halogen lamp of blast resistance construction.
Background technology
At present, existing high pressure tungsten halogen lamp comprises glass bulb, lamp base and molybdenum sheet, with reference to shown in Figure 1, is provided with bead 2, electrode supporting bar 3,4 and filament support bar 5 and filament 6 in glass bulb 1, and electrode supporting bar 3,4 is directly drawn with sealing-in molybdenum sheet 7,8 and is connected.When the tungsten halogen lamp of this structure fuses when filament, between electrode supporting bar, easily produce discharge, cause glass bulb to break easily and form blast, so generally all external in use fuse of this tungsten halogen lamp, make discharge off to guarantee blown fuse when discharge takes place, but,, common tungsten halogen lamp is restricted so using because the external meeting of fuse brings many drawbacks such as using inconvenience.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of explosion-proof tungsten halogen lamp, and this explosion-proof tungsten halogen lamp has explosion prevention function, and is simple in structure, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of explosion-proof tungsten halogen lamp comprises glass bulb, lamp base and sealing-in molybdenum sheet, be provided with bead, electrode supporting bar, filament support bar and filament in the glass bulb, bead is provided with the auxiliary rod that is connected with the sealing-in molybdenum sheet, and electrode supporting bar is connected with auxiliary rod by an one metal wire.
Described bead can be provided with an auxiliary rod, and a strip electrode support bar is connected with auxiliary rod by wire.
Described diameter range wiry can be 0.03mm-0.2mm.
The beneficial effects of the utility model are, can make common tungsten halogen lamp have explosion prevention function by increasing an one metal wire and auxiliary rod, need not external fuse, compact conformation, easy to use and be easy to produce.
Description of drawings
The structural representation of existing tungsten halogen lamp shown in Figure 1;
The structural representation of the explosion-proof tungsten halogen lamp of the utility model shown in Figure 2;
The structural representation of another embodiment of the explosion-proof tungsten halogen lamp of the utility model shown in Figure 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to shown in Figure 2, the explosion-proof tungsten halogen lamp of the utility model comprises glass bulb 1, lamp base 9 and sealing-in molybdenum sheet 7,8, be provided with bead 2, electrode supporting bar 3,4, filament support bar 5 and filament 6 in the glass bulb 1, filament support bar 5 can be the 1-4 root, is filled with the halogen compound gas body in the lamp.Bead 2 is provided with an auxiliary rod 10, and electrode supporting bar 3 is connected with auxiliary rod 10 by an one metal wire 11, and wire 11 is that a thinner metal material is made, and diameter range is 0.03mm-0.2mm.Electrode supporting bar 3, wire 11 and auxiliary rod 10 constitute electrical connection.When filament 6 fusing, produce discharge between the electrode supporting bar 3,4, electric current increases, and causes wire 11 fusing, makes discharge off between the electrode supporting bar 3,4, has prevented the blast of glass bulb 1.
With reference to shown in Figure 3, another embodiment of the present utility model is, bead 2 is provided with two auxiliary rods 10,12, electrode supporting bar 3 is connected with auxiliary rod 10 by wire 11 respectively, electrode supporting bar 4 is connected with auxiliary rod 12 by wire 13 respectively, and the diameter of wire 13 can be selected according to the operating current of lamp.Because wire and auxiliary rod are all adopted in both sides, and explosion-proof reliability is further improved.
The utility model is suitable for all tungsten halogen lamps that has bead.
