Abstract
The utility model provides an explosion-proof halogen tungsten lamp, including a glass shell, a light foot and a nipping flat. The inside of the glass shell is provided with a glass bead, an electrode supporting rod, a filament supporting rod and the filament. The glass bead is provided with an auxiliary rod which is connected with a sealing molybdenum plate. The electrode supporting rod is connected with the auxiliary rod by a metal wire which is placed inside the nipping flat. The electrode supporting rod, the auxiliary rod and the metal wire which is arranged inside the nipping flat form the electrical connection, which provides the ordinary halogen tungsten lamp with the function of preventing explosion and ensures that no fuse is required to be externally connected; the utility model has compact structure and is convenient for using and producing.
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 that glass bulb, lamp base and folder are flat, 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, electrode supporting bar is connected with auxiliary rod by an one metal wire, and it is flat that wire is positioned at folder.
Can be provided with cavity in described folder is flat, wire is arranged in the cavity.
Described bead can be provided with two auxiliary rods, and two strip electrode support bars are connected with auxiliary rod by wire respectively, and it is flat that two one metal wires are positioned at folder.
The beneficial effects of the utility model are, are arranged on wire and the auxiliary rod of folder in flat by increase and can make common tungsten halogen lamp have explosion prevention function, 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, sealing-in molybdenum sheet 7,8 and presss from both sides flat 12, 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, electrode supporting bar 3 is connected with auxiliary rod 10 by an one metal wire 11, in folder flat 12, be provided with enclosed cavity 13, the wire 11 some or all of flat cavitys 13 of folder that are positioned at, 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, cause wire 11 fusing, and the micro-spark that produces during wire 11 fusing is closed in the cavity, can not be splashed in the glass bulb 1, make discharge off between the electrode supporting bar 3,4, 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 10,14, electrode supporting bar 3 is connected with auxiliary rod 10 by wire 11 respectively, electrode supporting bar 4 is connected with auxiliary rod 14 by wire 15 respectively, the some or all of enclosed cavity 13,16 that is positioned at folder flat 12 of wire 11,15, the diameter of wire 11,15 can be selected according to the operating current of lamp.Be arranged on folder flat interior wire and auxiliary rod because all adopt on both sides, explosion-proof reliability is further improved.
The utility model is suitable for all tungsten halogen lamps that has bead.
