Christmans light string with the female lamp of three-wire type

The utility model relates to a kind of Christmans light string, is meant a kind of Christmans light string that includes the female lamp of three-wire type especially.

Existing Christmans light string structure (as shown in Figure 1) is to be reached by a series of Christmas lamp 11 of female lamp 10 serial connections of a TW two wire to be constituted with a plug 2.Wherein the female lamp 10 of TW two wire generally is to use the structure of the female lamp of type TW two wire that opens circuit, also be that it is to be provided with a bimetal leaf in a lampshade body interior, when bimetal leaf is not heated, electric current can pass through this mother's lamp, and after bimetal leaf is heated, contact is opened, and makes electric current then can't pass through this mother's lamp again.So can utilize this bimetal leaf and the light and shade flicker effect of this Christmans light string of may command.

Yet the existing Christmans light string of this kind only can be made simple flicker effect, so can't reach the effect of variation flicker on visual effect.Though lamp string that can string in parallel, its flicker effect still can't be broken away from the visual effect of original dull flicker.

In order to reach diversified lamp string flicker effect, be that the technology of using a controller is arranged in the prior art, in this controller, have the circuit of a flicker control.But be to use in the prior art of this kind electronic controller, the price of controller itself is comparatively expensive.

Main purpose of the present utility model promptly provides a kind of Christmans light string with the female lamp of three-wire type, and it is the Christmans light string with diversified flicker effect.

Another purpose of the present utility model provides a kind of Christmans light string with the female lamp of three-wire type, the Christmans light string structure of the simple and easy and special flicker effect of tool of its line arrangements.

The purpose of this utility model can reach by following measure: a kind of Christmans light string with the female lamp of three-wire type, include most lamp string loops,

Include the female lamp of a three-wire type in each lamp string loop, and the normally closed contact of the female lamp of each three-wire type is connected with one by the Christmans light string that several Christmas lamps were connected in series, a wherein end of each Christmans light string is to be connected to first power line;

The common joint of the female lamp of the three-wire type in first lamp string loop is to be connected to the second source line;

The common joint of the female lamp of the three-wire type in the back one-level lamp string loop is the normal opened contact that is connected to the female lamp of three-wire type of previous stage lamp string loop;

The normal opened contact of the female lamp of last three-wire type is serial connection one Christmans light string.

Wherein the normal opened contact of this last female lamp of three-wire type is that the serial connection one female lamp of type TW two wire that opens circuit is connected in series this Christmans light string again.

The female lamp of three-wire type wherein is the female lamp of the type three-wire type that opens circuit.

The female lamp of three-wire type wherein is the female lamp of maintenance three-wire type;

The common joint of the female lamp of maintenance three-wire type in its first lamp string loop is that the serial connection one female lamp of type TW two wire that opens circuit is connected to the second source line again.

The utility model has following advantage compared to existing technology:

In this lamp string rack structure, comprised the female lamp of at least one three-wire type, when the arrangement of circuit, the female lamp of this three-wire type is cooperated existing female lamp and lamp string, can reach special lamp string flicker effect, particularly in conjunction with several lamp strings the time, more can reach the effect that order is lit a lamp and glimmered;

Need not dispose under the situation of electronic controller,, promptly can combination in any go out the simple and easy effect that can reach lamp string variation flicker again of a wiring as long as utilize the female lamp of three-wire type of the present utility model to be arranged in appropriate location in the lamp string.
