Abstract
The utility model provides a single-end halogen lamp bulb of which the interior is provided with a safety device for current limiting and fusing so as to achieve the anti-explosion effect. The single-end halogen lamp bulb of the utility model is composed of a bulb body, filaments, support molybdenum wires, glass beads, electrode molybdenum wires and molybdenum sheets, wherein safety wires are arranged on the electrode molybdenum wires; the safety wires can be arranged on the electrode molybdenum wires between the glass beads and the molybdenum sheets, or are arranged on the electrode molybdenum wires of the glass beads, and can also be arranged on the electrode molybdenum wires between the glass beads and the filaments. The utility model is suitable for various single-end halogen lamp bulbs.
Description
Technical field
The utility model relates to a kind of bulb, particularly a kind of single end halogen bulb.
Background technology
The basic structure of traditional single-end halogen lamp is: the bead upper end has supports the filament that molybdenum wire is propped, the electrode molybdenum wire that is connected with filament is connected with molybdenum sheet by spot welding, thereby formation conductive path, because the electrode molybdenum wire diameter is thicker, and the fusing point of molybdenum is also higher, when electric current moment in the conductive path sharply increases, owing to do not play the safeties of metering function, gas in the bulb will be breakdown and produce arc discharge, gas temperature sharply rises in the bulb, causes air pressure to increase suddenly and causes the phenomenon of bulb blast.A kind of Halogen lamp LED that adds safeties is also arranged, it places fuse between the lamp base and the contact in the light fixture of bulb outside, though reached the effect of safety anti-explosive like this, but the parts assembling is very inconvenient, easily cause solder joint to come off again or the phenomenon of short circuit, and its bulb must be connected the effect that use just can reach safety anti-explosive with specific light fixture because of misoperation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of explosion-proof type single end halogen bulb of embedded with safety device.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of single end halogen bulb comprises foam, the filament in the foam, supports the molybdenum sheet in molybdenum wire, bead, electrode molybdenum wire and the clamping plate, under the molybdenum sheet lamp base is arranged, and fuse is housed constituting on the electrode molybdenum wire of current circuit with filament, molybdenum sheet; Described fuse perhaps is positioned on the electrode molybdenum wire at bead place on the electrode molybdenum wire between bead and the molybdenum sheet, also can be on the electrode molybdenum wire between bead and the filament.
The beneficial effects of the utility model are: fuse places bulb inside, makes convenient welding, and the metering function of fuse makes electric current can at first be fused when increasing, the cut-off current loop, thus reach the effect of safety anti-explosive; The bulb of built-in safeties is easy to use, and range of application is more extensive, not only can use by the hair bubble, also can be used for Lamp cup or other light fixture and need not connect safeties in addition again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structure chart of a kind of embodiment of the utility model;
Fig. 2 is the structure chart of the another kind of embodiment of the utility model;
Fig. 3 is the structure chart of the third embodiment of the utility model;
Fig. 4 is the structure chart of the 4th kind of embodiment of the utility model;
Fig. 5 is the structure chart of the 5th kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, the single end halogen bulb comprises filament 2 in the foam 1, foam 1, supports the molybdenum sheet 6 in molybdenum wire 3, bead 4, electrode molybdenum wire 5 and the clamping plate 9, molybdenum sheet has lamp base 86 times, fuse 7 is on the electrode molybdenum wire 5 between bead 4 and the molybdenum sheet 6, when adopting five line beads, the connection of its fuse can be adopted mode as shown in Figure 1, 2, 3, and fuse can be arranged in the foam 1 or be solidificated in the clamping plate 9.
With reference to Fig. 4, the fuse 7 in the bulb of the present utility model also can be arranged on bead 4 places, surrounds the bead outside, and original molybdenum filament in the bead is end to end, with molybdenum sheet 6, filament 2 one isomorphism current paths; Perhaps fuse 7 is arranged on the electrode molybdenum wire 5 between bead 4 and the filament 3, as shown in Figure 5.
Certainly, the link position of fuse is not limited to the mode shown in the embodiment, get final product so long as be connected the purpose that can play the fusing current limliting on the whole current path, when electric current moment in the conductive path sharply increases, because the fuse diameter is thinner, and fusing point is also lower, then fuse at first fuses, cut-off current, thus reach the effect of safety anti-explosive.
