Abstract
The utility model relates to a safety halogen lamp which comprises a bulb casing, wherein a bracket is fixedly arranged in the bulb casing, a tungsten filament is hung on the bracket and is divided into a right part and a left part, and an insulated post is arranged in the bulb casing between the right part and the left part of the tungsten filament. One end of the insulated post is fixed to the bracket, and the other end is fixed to the bulb casing through a clamping foot to separate the tungsten filament. When the tungsten filament is fused because of long-time work, tungsten filaments connected with two electrodes can not be contacted together, a short circuit phenomenon can not occur, and thus the explosion of the bulb casing and the burning of an external circuit can be avoided. The utility model has the advantages of simple structure, high safety, etc.
Description
Technical field:
The utility model relates to the Halogen lamp LED technical field, refers in particular to a kind ofly can effectively prevent tungsten filament fusing and cause short circuit, the higher safe Halogen lamp LED of security performance.
Background technology:
Halogen lamp LED is that a kind of inside is filled with halogen family gas, makes the novel lamp of filament with tungsten filament, and it has little, the advantage such as can work long hours of volume, therefore is widely used in commercial field.At present, common Halogen lamp LED is to be made of cell-shell, filament, support, molybdenum sheet, molybdenum pin etc.; Support supports the filament mid portion firm, and the both positive and negative polarity that connects power supply is drawn through molybdenum sheet and molybdenum pin respectively in the two ends of filament from an end of cell-shell.Because the Halogen lamp LED volume is little, so filament is by the separated two parts close together of support, make when heat is too high in the lamp body when working long hours, may cause filament to be fused, thereby the arc discharge that produces sharply increases the cell-shell internal gas pressure, thereby causes the cell-shell blast, and before fusing, cause by the electric current of filament excessive, thereby external circuit is burnt.Security performance is relatively poor.Also there is manufacturer's crosswise fixed in cell-shell that glass supporter is arranged at present, tungsten filament is hung on this glass supporter again, but this structure still may be when tungsten filament fuses, and the tungsten filament of fusing touches the tungsten filament that links to each other with another electrode and causes short circuit, i.e. the above-mentioned safety problem of unresolved Halogen lamp LED still.
Summary of the invention:
The purpose of this utility model is to provide a kind of tungsten filament that can not cause fusing when tungsten filament fuses to touch mutually at the deficiencies in the prior art and cause safe Halogen lamp LED short circuit, that security performance is higher.
For achieving the above object, the utility model adopts following technical scheme: it includes cell-shell, and the cell-shell internal fixation has support, and tungsten filament hangs over and is divided into left and right sides two parts on the support, and the cell-shell internal fixation between two parts tungsten filament of the left and right sides has insulated column.
Described insulated column one end is fixed on the support, and the other end is fixed on the cell-shell by card base.
Described insulated column and cell-shell are one-body molded.
The utility model is provided with insulated column in cell-shell, tungsten filament is separated, and when causing tungsten filament fusing when working long hours, the tungsten filament that links to each other with two electrodes can not touch together yet, promptly can not produce short circuit phenomenon, thereby has avoided the cell-shell blast and burnt external circuit.The utlity model has simple in structure, security performance than advantages such as height.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is two of a structural representation of the present utility model.
Embodiment:
Embodiment sees accompanying drawing 1, accompanying drawing 2, and the utility model includes cell-shell 10, and cell-shell 10 internal fixation have support 20, and tungsten filament 30 hangs over and is divided into left and right sides two parts on the support 20, and promptly the middle part of tungsten filament 30 hangs on the support 20; Two parts do not touch together about when fusing for tungsten filament 30 is expanded, and the length that tungsten filament 30 hangs on the support 20 can be big slightly; Support 20 adopts the metal molybdenum material, also participates in the conduction of tungsten filament 30.
Left and right sides two parts of tungsten filament 30 connect the molybdenum sheet 12 of cell-shell 10 lower ends respectively, and link to each other with the both positive and negative polarity of power supply by molybdenum pin 14.
Cell-shell 10 internal fixation between left and right sides two parts tungsten filament 30 have insulated column 40.
The utility model is in actual production process, and the feet of support 20 is fixed on the end of insulated column 40, and insulated column 40 other ends are fixed on the cell-shell by card base 50.In embodiment 2, insulated column 40 is one-body molded with cell-shell 10, and insulated column 40 adopts quartzy the making, makes insulated column 40 consistent with the coefficient of thermal expansion of cell-shell 10, and has optimized production technology.
Cause tungsten filament 30 high temperature fusing when working long hours, the tungsten filament 30 of fusing is also because the obstruct of insulated column 40 and short circuit mutually, thereby can not cause that cell-shell 10 explodes and burns external circuit, has improved coefficient of safety greatly.
The utlity model has advantages such as simple in structure, that security performance is better.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
