The lamp is characterized in that: two ends of the filament are supported by solid bolts, one of which is in joint with a molybdenum foil and the other of which is in joint with a foil strip 1; the filament is further supported and fastened by a plurality of metal wires to be parallel to an insulating rod; a return wire is welded between the foil strip 1 and a foil strip 2 and is separated from the filament by the insulating rod; two ends of the insulating rod are fastened by two metal wire 2 respectively; and the other ends of the two metal wires are welded onto the foil strip 1 and the foil strip 2 respectively. When the lamp is completely assembled, a screw mount or a bayonet mount is provided at the bottom of a shell of the lamp, and the return wire extends to a protruding part at the top end of the shell. The lamp is advantaged by a simple structure, low costs, convenient usage, and a beautiful exterior. The probability of return wire or filament breakdown is reduced, and thus the lamp is durable.

Description

Single-ended wire filament incandescent lamp

Technical field

The utility model relates to the illuminations in a kind of daily life, particularly a kind of single-ended wire filament incandescent lamp.

Background technology

A lot of incandescent lamps is generally the both-end structure at present, and the tail end of lamp housing is traditional pinch-sealed, seals built-in conduction molybdenum pool.Yet in some cases, especially when power be 200 watts and when following, bulb may be single-ended structure, at this moment, electric current ends at the crown top of burner of traditional inner welding of energy.Although still adopt the suitable wire filament of size, there is a single seal area on the lamp housing top of this lamp, two and above molybdenum pool, at seal area and between the glower end of apart from each other one section return wire is arranged with it, but this Single-ended Lamp is faced with the danger that the tie point between loop line and the filament punctures usually.

The utility model content

It is a kind of through the single-ended wire filament incandescent lamp raising type and that reduce loop line and the breakdown probability of filament, in order to solve above-mentioned existing issue that the purpose of this utility model has been to provide.

The technical solution of the utility model is as follows: a kind of single-ended wire filament incandescent lamp, and it is characterized in that: the two ends of described heater winding are supported by the solid latch, and one of them latch is engaged on the molybdenum pool, and another is engaged on the foil one; Described heater winding is further supported fixing by a plurality of wires one, so that heater winding is parallel with insulating rod; Be welded with loop line between described foil one and the foil two, and loop line and heater winding are insulated rod institute and separate; Two of described insulating rod is all fixing by two sections wires two, and other two of wire two is soldered to respectively on foil one and the foil two.

Described incandescent lamp is assembled when complete has cap nut or bayonet cap in the bottom of lamp housing, and loop line extends to the ledge on lamp housing top.

The beneficial effects of the utility model are: simple in structure, with low cost, convenient and practical, good looking appearance is generous, has reduced the breakdown probability of loop line and filament,, durable.

Embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, the single-ended wire filament incandescent lamp of the utility model, it is characterized in that: the two ends of described heater winding 1 are supported by solid latch 2, and one of them latch is engaged on the molybdenum pool 3, and another is engaged on the foil 1; Described heater winding 1 is further supported fixing by a plurality of wires 1, so that heater winding 1 is parallel with insulating rod 6; Be welded with loop line 7 between described foil 1 and the foil 28, and loop line 7 is insulated 6 of rods with heater winding 1 and separates; Two of described insulating rod 6 is all fixing by two sections wires 29, and other two of wire 29 is soldered to respectively on foil 1 and the foil 28.Described incandescent lamp is assembled when complete has cap nut 16 or bayonet cap 17 in the bottom of lamp housing 18, and loop line 7 extends to the ledge 19 on lamp housing 18 tops.

As shown in the figure, only shown the filament assembly of this utility model at Fig. 1, do not comprised the crown top of burner, lamp housing and sealing lead.In this drawing, heater winding 1 is the form demonstration with overall schematic, its two ends are supported by solid latch 2, a latch is soldered on the molybdenum pool 3, another latch is soldered to foil 1, wherein molybdenum pool 3 is parts of lamp housing seal, but foil 1 optional be the part of seal.

Parallel with rigid insulation rod 6 for guaranteeing filament, heater winding 1 is further supported fixing by a plurality of wires 5, this insulating rod 6 can be made by the high glass of dioxide-containing silica, the alumino-silicate that fusing point is higher or borosilicate glass or pottery, but be the preferred for quartzy of tungsten halogen lamp.And loop line 7 typically has a diameter between the 0.4-0.5cm, further is welded to foil 4 and pool and is with 8.As shown in Figure 1 and Figure 2, insulating rod 6 is further fixing by wire 29, and wire 29 is welded to respectively on foil 4 and 8, has consisted of so a single firmly filament assembly, and is also more convenient when being inserted in fluorescent tube.And wire 29 and loop line 7 can continue to extend to the ledge 19(on lamp housing top shown in Fig. 3,4 along 7', 9' direction) so that this end of filament assembly be fixed in the lamp housing better.In this structure, the effect of insulating bar 6 is apparent, reduces the tendency that produces electric arc between heater winding 1 and the loop line 7 to I haven't seen you for ages.
