Abstract
The utility model relates to a light socket, and is composed of two lamp sockets which form a whole body by adopting a tandem-type connection. When two same power capacity bulbs whose rated voltages are 220V are connected into commercial power circuit, the electric voltage added on every bulb is only half of commercial power electric voltage and the power capacity of the bulb is also only one fourth of the nominal power capacity. When the bulb works under the low power consumption state, the life time of the bulb is increased. The utility model is especially suitable for being installed on the place requiring overnight illumination, and can avoid the situation that the life time of the bulb is cut down and even be scorched out when the commercial power electric voltage is increased. But because the bulb works under the voltage reduction state, the luminescence efficiency is also cut down.
Description
The utility model belongs to light socket.
At present, single lamp socket of installing and using in the place (as stair, passage, night shift room, street etc.) that needs throw light on all night, often because of night line voltage higher, bulb life is shortened greatly, even can burn.Thereby need often more to change the bulb, bring inconvenience for people's work and life.
The purpose of this utility model is to provide a kind of Double lamp socket that can improve bulb life greatly.
This Double lamp socket provided by the utility model is to constitute an integral body by two lamp sockets, and it is made up of housing, loam cake, conduction screw line, compressing tablet power spring, contact rod, lamp socket etc.Adopt tandem-type connection, according to electrician's voltage divider principle, when two rated voltages are 220V, the bulb that power is identical, the 220V alternating current circuit is inserted in the series connection back, then is added in the voltage on each bulb, equals half of line voltage, i.e. 110V.The power of bulb is P=V
2/ R.Wherein the impedance R of bulb is constant, and works as voltage and reduce by a half, the power P of bulb=(1/2 V)
2/ R=1/4 P, promptly the power of each bulb of series connection back only equals 1/4 of its nominal power.When rising to 250V as line voltage, the power of each series connection bulb is about 1/3 of bulb nominal power.Bulb is worked under this low power consumpting state, and its life-span can prolong greatly; And be difficult for being burnt.But owing to bulb is worked under step-down, to its luminous efficiency is also descended to some extent.
Double lamp socket provided by the utility model has advantages such as high pressure resistant, bulb service life length, needing to be suitable for the place of illumination all night to install and use.
