Abstract
The utility model provides a lamp holder capable of prolonging the service life of an incandescent bulb, belonging to an electric device. Connecting terminals (2), (7) are arranged in a casing (1) with two lamp sockets; a fixed contact (4) in one lamp socket is connected to the connecting terminal (2); an elastic contact (3) is connected with a fixed contact (5) in the other lamp socket together; an elastic contact (6) in the other lamp socket is connected to the connecting terminal (7); the utility model has the advantages that voltage on each bulb is reduced, and the service life of the incandescent lamp is prolonged; the utility model is especially suitable for corridors, toilets, stations, etc. with low requirement to illumination intensity.
Description
The utility model provides a kind of electric device, especially a kind of lamp socket.
Original incandescent lamp lamp socket has only a socket, and an incandescent lamp bulb only is installed during use, and only have about 1000 hours the useful life of bulb.Because the external causes such as fluctuation of line voltage cause hundreds of is only arranged individual hour the useful life of incandescent lamp bulb, even shorter.This has just caused the waste of incandescent lamp bulb and the trouble of frequent maintain and replace.
The purpose of this utility model provides a kind of incandescent lamp bulb lamp socket in useful life that prolongs, to reduce the waste of incandescent lamp bulb.
The utility model is to realize like this, a kind of incandescent lamp lamp socket in useful life that prolongs, the outer cover internal fixation that has two sockets has binding post and another binding post, the fixed contact that fixed contact and binding post in one socket connects together, elastic force contact and another socket are interior connects together, and interior elastic force contact and another binding post of another socket connects together.
Adopt a kind of incandescent lamp lamp socket in useful life that prolongs of said structure, can reduce the voltage of two incandescent lamp bulbs of mounted thereto installation, improved its useful life (approximately can reach about 50000 hours) greatly, reduce the waste of incandescent lamp bulb, greatly reduced the workload of maintain and replace incandescent lamp bulb simultaneously.Be specially adapted to corridor, lavatory, the less demanding occasion of station equiluminous.
Below in conjunction with description of drawings structure of the present utility model and operation principle.
Fig. 1 is the schematic diagram of the utility model structure.Fig. 2 is its fundamental diagram.
As shown in drawings, a kind of incandescent lamp bulb lamp socket in useful life that prolongs of the utility model, it is characterized in that, outer cover (1) internal fixation that has two sockets has binding post (2) and another binding post (7), fixed contact (4) in one socket connects together with binding post (2), elastic force contact (3) connects together with fixed contact (5) in another socket, and the elastic force contact (6) in another socket connects together with another binding post (7).
With reference to the accompanying drawings, during use, live wire, the zero line of AC power is connected on respectively on binding post (7) and the binding post (2).Two incandescent lamp bulbs are installed on the socket, the contact in contact and the socket on the bulb is contacted.After the energized, just formed the loop of binding post (7) → elastic force contact (6) → bulb → fixed contact (5) → elastic force contact (3) → another bulb → fixed contact (4) → binding post (2), two bulbs are series relationship.The voltage that is added in like this on each bulb is supply voltage half (equating to be example with two bulb powers), and the ability of external factor such as incandescent lamp bulb opposing voltage ripple of power network strengthens greatly like this, and the life-span prolongs greatly.
The lamp socket manufacturing of the utility model is simple, and the production investment is little.Can be equipped with suitable lampshade according to different environmental requirements, make the lamp socket of different purposes.As ceiling lamp holder, floor lamp lamp socket and waterproof, rainproof, explosion-proof lamp etc.
Claims (1)
