Abstract

The utility model relates to a long-life AC light overlapping incandescent lamp, which comprises a glass shell and a lamp holder with two electrodes, wherein, two sets of filaments are respectively erected in the glass shell; one end of each of the two sets of the filaments is switched on with the first electrode on the lamp holder after mutually connected; the other end of each of one set of the filaments is connected with a positive electrode of a diode; a negative electrode of the diode is switched on with the second electrode of the lamp holder; the other end of each of the other set of the filaments is connected with the negative electrode of the diode; the positive electrode of the diode is also switched on with the second electrode on the lamp holder. The utility model can increase the service life of the incandescent lamp by one time.

Description

The long-lived interchange folded the light incandescent lamp

The utility model relates to the illumination incandescent lamp, especially a kind of long-lived incandescent lamp that exchanges.

Existing incandescent lamp is to set up one group of filament in glass shell mostly, and after the two ends of filament are drawn in the glass shell respectively with lamp socket on two electrodes connect formation.Its damage mode of this incandescent lamp nearly all is to cause because of wherein filament is disconnected, and other parts are often still quite intact, and the waste of abandoning is unfortunate.

The purpose of this utility model provides the long longevity of a kind of burn-out life and exchanges folded light incandescent lamp.

For achieving the above object, the scheme that the utility model adopts is: it has the glass shell identical with ordinary incandescent lamp and has the lamp socket of two electrodes, set up two groups of filaments in the described glass shell respectively, an end of these two groups of filaments is coupled to each other the back and connects with first electrode on the described lamp socket; Wherein the other end of one group of filament connects with a diode cathode, second electrode on the negative pole of this diode and the described lamp socket connected, other end of another group filament connects with a diode cathode, the positive pole of this diode also with described lamp socket on the connection of second electrode.

Two above-mentioned diodes can be located in the described glass shell, also can be located between described glass shell and the described lamp socket, so that the heat radiation of diode.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, long service life.Owing to be provided with two groups of filaments, and every group of filament be in series with a diode, and this scheme can make two groups of filament alternations, consequently makes prolong one times the useful life of incandescent lamp.

2, good economy performance.Compared with prior art, though increased its cost less than one group of filament of an incandescent lamp, two diodes, prolonged one times its useful life, thereby better economy, in addition, also reduced the work that more renews lamp.

The utility model is described in further detail below in conjunction with the accompanying drawing example:

Structural representation when Fig. 1 is the utility model work.

Among the embodiment shown in Figure 1, the utility model includes the glass shell identical with ordinary incandescent lamp 6 and has the lamp socket 1 of electrode 2 and electrode 3, set up 11 liang of groups of filament 10 and filament filament in the described glass shell 6 respectively, an end of 11 liang of groups of filament 10 and filament filament is coupled to each other and connects by first electrode 2 that lead 7 is drawn outside the glass shell 6 and on the lamp socket 1; The other end of filament 10 is drawn outside the glass shell 6 by lead 8 and is connected with the positive pole of a diode 4, second electrode 3 on the negative pole of this diode 4 and the described lamp socket 1 connected, the other end of another group filament 11 is drawn outside the glass shell 6 by lead 9 and is connected with the negative pole of a diode 5, and second electrode 3 on the positive pole of this diode 5 and the described lamp socket 1 connected.

Owing to be provided with 11 liang of groups of filament 10 and filament filament, and every group of filament be in series with a diode 4,5 respectively, and this scheme can make two groups of filament alternations, consequently can make prolong one times the useful life of incandescent lamp.
