Description

A kind of plug with rectification function

Technical field

The utility model belongs to the technical field of the light decoration light fitting of electric lighting, relates to the circuit connection structure that is used for LED lamp string, and more particularly, the utility model relates to a kind of plug with rectification function.

Background technology

Because the LED light fixture has long, energy-conservation, power saving of life-span, caloric value little, beautiful in colour, so the use of LED lamp string is more and more universal, LED lamp string is replacing the tungsten lamp string fast.

Present general lighting power supply is alternating current.And LED lamp string requires to use under DC power supply, this is because interchange makes the lamp string that the unsteadiness of flicker be arranged, add the continuous impact of alternating current to led chip, the LED life-span is reduced fast, because of single led all be low-voltage, LED lamp string all is use that are connected together of a lot of LED bulb strings in actual the use, opens circuit owing to a LED bulb like this, causes that to put in order the phenomenon that cluster of lamps, ornamental string do not work very serious.So rectification is necessary.

LED lamp string uses more and more universal, and DC power supply need be through over commutation, and special DC power supply cost height uses very inconvenient for LED lamp string.

In the present use, all be before LED lamp string, to add full-bridge or two half-bridge rectifications are finished.The disclosed patented technology that just relates to foregoing circuit of following patent documentation:

United States Patent (USP): US6461019B1; Chinese patent: ZL200520128034.5 etc.

In the known technology of the existing LED of relating to that comprises above-mentioned patented technology, the problem of its method for rectifying and existence is:

1, directly full-bridge rectification is added in LED lamp string before, its shortcoming is to be connected in series continuously, if serial connection needs the waste main line, increases production cost.

2, the method that can be connected in series the lamp string continuously is to add a half-bridge before every unit LEDs lamp string, behind every unit LEDs lamp string, add and add another half-bridge again, to reach the effect of full-bridge rectification, because LED lamp string is considered power saving, can form a string by a lot of unit like this, and the functions that polyphone is inserted more than having, shortcoming just comes out like this, all has two places to be connected with two poles during every unit LEDs lamp connection in series-parallel, because every place all wants injection mo(u)lding, extremely inconvenient during production, cause short circuit easily, complex manufacturing is produced extremely inconvenient, for the characteristic that many series connections are arranged in the actual use of LED lamp string, production cost height.
