Abstract

The utility model discloses a lamp holder which can extend the service life of an incandescent lamp. The lamp holder is suitable for incandescent bulbs. The input terminal and the output terminal of the lamp holder are communicated through a rectifying circuit. The lamp holder converts alternating current to direct current and supplies the direct current to a bulb. The service life of the bulb can be extended by 50-100 times. The input terminal of the lamp holder is matched with an existing incandescent lamp holder. The cap of the lamp holder is taken off, and the lamp holder of the utility model can be arranged on the existing incandescent lamp holder to be used.

Description

Lamp holder capable to prolong the life of incandescence lamp

The utility model is a kind of improved incandescent lamp holder, and particularly a kind of lamp socket that can prolong the incandescent lamp bulb life-span is suitable for incandescent lamp bulb.

Existing incandescent lamp holder only plays bulb and connects power supply, the function that does not prolong bulb life.

Task of the present utility model is that a kind of improved incandescent lamp holder will be provided, and it can prolong the life-span of incandescent lamp bulb.

Task of the present utility model is finished as follows:

According to the phenomenon that the incandescent lamp DC operation life-span can prolong, the U.S. that " electric light source " magazine 3 phases of nineteen eighty-three carry is contained in the test of bulb top with rectifier, and the result shows that bulb life prolongs 50～100 times.The rectification circuit of lamp socket is connected input terminal and lead-out terminal, input terminal connects AC power, the bulb that is contained on the lead-out terminal has just been kept supplying direct current, reached the purpose of incandescent lamp bulb life-saving, the input terminal of lamp socket matches with existing lamp socket, therefore, lamp socket can also be contained on the existing lamp socket and use, and only needs during use the seat cap is taken off.

The utility model accompanying drawing has four:

Fig. 1: the lamp socket schematic diagram that prolongs the incandescent lamp bulb life-span.

Fig. 2: the lamp socket rectification circuit figure that prolongs the incandescent lamp bulb life-span.

Fig. 3: the lamp socket input subgraph that prolongs the incandescent lamp bulb life-span.

Fig. 4: the lamp socket output subgraph that prolongs the incandescent lamp bulb life-span.

Below with reference to example the utility model is described in further detail:

Embodiment one:

With reference to Fig. 1,2,3,4, rectifying block (11) is contained in the input terminal (9), the interchange lead-out wire (1 ') of rectification circuit piece (11), the contact screw (5) of (2 ') and input terminal (9), (6) join, the direct current lead-out wire (3 ') of rectification circuit piece (11), the contact stud (7) of (4 ') and lead-out terminal, (8) join, with attaching nut (12) input terminal (9) and lead-out terminal (10) are connected to one, the contact screw (5) of input terminal (9), (6) connect AC power, the contact stud (7) of lead-out terminal (10), (8) keep supplying direct current just for the incandescent lamp bulb that is contained on the lead-out terminal (10), can prolong 50～100 times with incandescent lamp bulb life-span of this lamp socket.Good effect is obvious.

Embodiment two:

Prolong in the lamp socket in incandescent lamp bulb life-span at embodiment, input, lead-out terminal and used screw lamp holder, lamp holder are supporting, and the screw socket incandescent lamp bulb just can use like this.

Claims

1, the lamp socket that constitutes by input terminal, rectification circuit, lead-out terminal, binding nut, seat cap, it is characterized in that the interchange lead-out wire of rectification circuit and the contact screw of input terminal join, the direct current lead-out wire of rectification circuit and the contact stud of lead-out terminal join, input terminal is connected AC power, and the bulb that is contained on the lead-out terminal has just been kept supplying direct current.

2, lamp socket according to claim 1 is characterized in that the input terminal of lamp socket matches with existing lamp socket, and therefore, lamp socket can also be contained on the existing lamp socket and use, and only needs during use the crown top of burner is taken off.
