Abstract

The utility model relates to a universal long life incandescent lamp with two filaments. The common tungsten filament bulb has short service life. When one set of lamp filament is burnt, the bulb is rotated, the bulb is clamped on the other bayonet of the lamp holder with bidirectional bayonets, and another set of lamp filament is used. The utility model extends the service life of the bulb or changes the brightness of the bulb, and has simple structure, convenient manufacture, easy use and low cost. The common incandescent lamp is used on the lamp holder provided by the utility model.

Description

Universal longlife incandescent lamp with two filaments

The utility model belongs to illumination mariages incandescent lamp apparatus.

Common tungsten lamp low cost of manufacture, easy to use, so it is widely used for illumination and decorates.In case but behind its unique filament blow of this incandescent lamp, whole bulb just can not continue to have used, this has just limited the useful life of incandescent lamp.Notification number provides a kind of mariages or multi-wire incandescent lamp for the patent application of GG85200794 in Patent Office of the People's Republic of China's utility application bulletin, it can make bulb longevity and can regulate luminous intensity, but this bulb needs supporting uses such as multiple special lamp cap, screw socket, socket and conversion socket.Increase these parts peculiars, just make the production cost increase very big.

The purpose of this utility model is that a kind of improved mariages incandescent lamp light fixture will be provided, also can use common monofilament incandescent lamp bulb on the lamp socket of this light fixture, the mariages incandescent lamp bulb life-span of this light fixture is long, easy to use, and whole light fixture applicability is strong, cost is low, suitable batch production.

The utility model is realized as follows: the mariages Incandescence lamp holder that the top is had the electrode of three annular spread is connected to arbitrary bayonet socket place on the lamp socket that has two-way bayonet socket, and bulb has one group of filament light-emitting; If the reverse rotation bulb is connected on another bayonet socket lamp holder, just can make another group filament light-emitting.Like this, can prolong one times the useful life of bulb, if filament wattage difference in the bulb, the brightness of the light that also changes.

Incandescent lamp of the present utility model as shown in Figure 1.Common leads (1) is connected with electrode (4), and two lead-in wires (2) link to each other with (5) with electrode (4) respectively with (3) in addition.Two groups of filaments are by same glass shore supports, and diverse location is between the two determined can not collide another group filament behind one group of filament blow wherein.

Lamp holder of the present utility model top as shown in Figure 2.Three electrodes circularize distribution, and electrode (4) is a common electrode.Between electrode (5) and (6) mm clearance should be arranged.

Lamp socket of the present utility model as shown in Figure 3.The two-way bayonet socket that has positive and negative both direction at its clamping bulb place.After being connected to bulb on the lamp socket clockwise, electrode (4) and (5) energising, the then filament light-emitting between the lead-in wire (1) and (2).If this group filament blow in the time of maybe will changing one group of filament, need only rotate the bulb inhour, make it to be connected on another bayonet socket, electrode (4) and (6) energising at this moment, the filament that lead-in wire (1) and (3) connects is just luminous.So just changed light-emitting filament.

The said structure light fixture that the utility model provides, its holder structure is reasonable, and is easily manufactured, and also can use common monofilament incandescent lamp on its lamp socket, highly versatile. Whole bulb and lamp socket are worked good, and the conversion filament is convenient, and Extension for Incandescent Lamp Life or change brightness are very easily popularized and used effectively.

The utility model can be made into following two kinds of bulbs according to the purposes difference:

When 1, using, make two groups of filaments that power is identical in the place that does not need to change brightness of illumination, wherein one group blow after, bulb is snapped fit onto on another bayonet socket, can use another group filament, prolong bulb service life.

2, requiring to change the use of brightness of illumination part, at this moment can be made into two groups of filaments that power is different.For example make the filament of two groups 25 watts and 40 watts, just can press the power of 25 watts of different needs generations or 40 watts.

Claims (2)

1, a kind of incandescent lamp light fixture with two groups of filaments is made up of bulb and lamp socket, it is characterized in that,

The electrode [4] of the common leads on the lamp holder top of a, above-mentioned light fixture and other two independent electrode [5] and [6] of lead-in wire of using are annular spread,

The lamp socket of b, described light fixture has two pairs of bayonet sockets of using for the electrode of conversion heater leads of can clamping living lamp holder.

2,, it is characterized in that forming by the filament of two groups of diverse locations on the glass pillar of bulb according to the described incandescent lamp light fixture of claim 1.
