Abstract
The utility model discloses an explosion prevention single ended halogen tungsten lamp, comprising a bulb 10, a bead 30, a lamp filament 40, a lamp filament 50, a leading foot 60 and a molybdenum foil 80 between the lamp filament 50 and the leading foot 60. Before connected to the leading foot 60, the lamp filament 40 is required to be connected with at least a fuse 70 in series. Compared with the prior technique, the utility model is provided with a structure of the explosion preventing fuse and the fuse is burnt out quickly to cut off the voltaic arc when the voltaic arc occurs, preventing the lasting and overspreading of the voltaic arc and the explosion when the lamp filament is burnt out. Thus, the utility model has the advantage of safe use.
Description
Technical field the utility model relates to the luminescent device of electric lighting device, particularly relates to the explosion-proof type structure of explosion-proof single-ended tungsten halogen lamp.
Do not have cutout mechanism in the single-ended tungsten halogen lamp of background technology prior art, this tungsten halogen lamp can died of old age or accident when burning molybdenum filament electrode leads to client generation arc discharge on bead because of filament, burn the hardware in the bulb, and the generation HTHP, explosion caused, damage.
The summary of the invention the purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of explosion-proof single-ended tungsten halogen lamp that prevents glass bulb blast.
The purpose of this utility model can be by realizing by the following technical solutions:
A kind of explosion-proof single-ended tungsten halogen lamp comprises the molybdenum foil between glass bulb, bead, filament, electrode, leading foot and described electrode and the leading foot, and described filament was in series with a fuse at least before being connected to leading foot.
Compared with prior art, the utlity model has explosion-proof safety structure, fuse blew and breaking arc rapidly when electric arc produced, thereby the continuing and expansion of the electric arc that produces can prevent the disintegration of filament time, thereby prevented that blast from taking place, and has advantage safe in utilization.
