Abstract
The utility model discloses a double-ended halogen lamp which comprises a lamp tube, a lamp filament sealed in the lamp tube and molybdenum pieces at both ends of the lamp tube. The molybdenum pieces are connected with electrodes outside the lamp tube. Both ends of the lamp filament are connected with tantalum pieces. The tantalum pieces are connected and fixed with the molybdenum pieces at both ends of the lamp tube. According to the double-end halogen lamp, the lamp filament is used for being connected with the tantalum pieces, and then the tantalum pieces are connected and fixed with the molybdenum pieces, thus the connected lamp filament is stable, the luminous efficiency is high, and the service life of the lamp filament is prolonged.
Description
Technical field
The utility model relates to field of illuminating lamps, particularly a kind of double-ended halogen lamp.
Background technology
Based on halogen bulb also claims the tungsten sodium lamp bubble, is a kind of of incandescent lamp, and principle is to inject the halogen gass such as iodine or bromine in bulb.At high temperature, the tungsten filament of distillation and halogen carry out chemical action, and the tungsten of distillation can be set on the tungsten filament again, form the circulation of balance, avoid the tungsten filament premature failure.Therefore based on halogen bulb is more long-lived than incandescent lamp, based on halogen bulb commonly used has single-end halogen lamp and double-ended halogen lamp, the molybdenum sheet that existing double-ended halogen lamp comprises fluorescent tube, is enclosed in the filament in the fluorescent tube and is located at lamp tube ends, molybdenum sheet is connected with fluorescent tube electrode outward, the two ends of filament are connected with molybdenum sheet, filament is to adopt common spot welding to be connected with molybdenum sheet, cause the brightness of filament lower, and the useful life of filament is not long.
Summary of the invention
In order to overcome defects, the utility model provides a kind of light efficiency higher, the double-ended halogen lamp of longer service life.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of double-ended halogen lamp, comprise fluorescent tube, be encapsulated in the filament in the fluorescent tube and be positioned at the molybdenum sheet of lamp tube ends, described molybdenum sheet is connected with fluorescent tube electrode outward, the two ends of described filament all are connected with tantalum piece, and tantalum piece is connected and fixed on the molybdenum sheet of lamp tube ends.
As further improvement of the utility model, described tantalum piece is fixedly welded on the molybdenum sheet of lamp tube ends.
The beneficial effects of the utility model are: this double-ended halogen lamp adopts filament to connect tantalum piece, tantalum piece is fixedly connected on the molybdenum sheet again, can make like this filament after the connection more stable, and light efficiency is higher, and has prolonged the useful life of filament.
