Abstract

The utility model discloses a single-end halogen lamp with metallic filament hooked by wire. The utility model facilitates the production operation produce-operation, overcomes the arc discharge phenomenon and prolongs the service life. The utility model comprises a bulb body (1) and a corresponding electric pole return circuit. The electric pole return circuit is composed of a lamp filament (3), a molybdenum plate (4) respectively connected in series with both the ends of the lamp filament (3) and a lamppress (5). The electric pole return circuit also comprises a metallic filament hook (2) arranged in the bulb (1) and used for hooking the lamp filament (3). The metallic filament hook (2) is fixed into the bulb body (1) though the bulb body thermal compression bonding position corresponding to the other end of the lamppress (5) of the bulb body (1). The utility model is used for lighting.

Description

Collude the single-end halogen lamp of hook filament with wire

Technical field

The utility model relates to a kind of single-end halogen lamp, particularly a kind of single-end halogen lamp that colludes the hook filament with wire.

Background technology

Traditional single-end halogen lamp is with the bead metallic support and the bulb thermal synthesis one of a band molybdenum filament, it is fixed in the bulb, the bead metallic support is used for supporting filament, the shortcoming of this structure is: these complicated bead metallic supports are because be on the electrode position of high voltage bulb, be easy between metallic support, cause arc discharge because of filament breaking, in case arc discharge will bring the danger of lamp pearl blast, the operant level to the direct labor during production is had relatively high expectations; Existing another kind of single-end halogen lamp is without any need for support, directly with part bulb and filament heat seal together, filament directly is fixed on the bulb, and this structural manufacturing process complexity is to the equipment requirements height, want post forming, many one procedure have increased production cost.

Summary of the invention

The utility model is at prior art problems, provide a kind of production operation simple, overcome arc discharge collude the single-end halogen lamp of hook filament with wire.

A kind of single-end halogen lamp that colludes the hook filament with wire, comprise: bulb and corresponding electrode loop, transition welding molybdenum sheet and lamp base that described electrode loop is connected respectively by filament, with the filament two ends are formed, comprise that also the wire that places in the bulb, is used for the hook filament colludes, described wire was worked hard in glove with in bulb with respect to the other end bulb hot pressing position of lamp base and was fixed in the bulb.

The hook-shaped shape of described wire is the U-shaped that opening is widened, and respectively curves one at the both ends of opening and colludes.

As a kind of preferred version of the present utility model, it is to make with molybdenum filament that described wire colludes.

As another kind of preferred version of the present utility model, it is to make with tungsten filament that described wire colludes.

Because the utility model adopts technique scheme, collude with wire and to replace the bead metallic support, stopped the source that the bead metallic support discharges foreign gas, obtain prolonging the useful life of bulb about 30%; Filamentray structure is simple, production technology is more tended to be reasonable, save a large amount of artificial, especially the workman cultivates difficulty and significantly reduces, at existing halogen Single-ended Lamp, the utility model can also be saved at least 80% molybdenum filament material, makes large-scale production more feasible, it is about 20% that the utility model can improve light efficiency than traditional bulb, has remarkable energy saving effect.

Embodiment

1-2 is further described the utility model in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, the utility model comprises bulb 1 and places electrode loop in the bulb 1, described electrode loop is by filament 3, form with transition welding molybdenum sheet 4 and the lamp base 5 connected respectively in filament 3 two ends, described transition welding molybdenum sheet 4 sealings by fusing are in bulb 1, described lamp base 5 stretches out outside the bulb 1, also comprise and placing in the bulb 1, the wire that is used for hook filament 3 colludes 2, described wire colludes 2 and is fixed in the bulb 1 by the other end bulb hot pressing position 6 with respect to lamp base 5 in bulb 1, it is U-shapeds that opening is widened that described wire colludes 2, respectively curves one at the both ends of opening and colludes 21.

Described wire colludes 2 can use the tungsten filament manufacturing, also can make with molybdenum filament.

Claims
