Description
Technical field
The utility model relates to LED decorative lamp field, especially a kind of improved connecting circuit that is used to connect the LED lamp that comprises one or more tie points.
Background technology
Because light-emitting diode (LED) has superior functions such as high reliability, low power consuming, low working temperature and long life, by being applied on Christmas lights and other various decorative lamps more and more widely.The manufacturer of LED lamp decoration when maximization improves the brightness of LED lamp and other advantage, the gap between the production cost that dwindles LED lamp decoration and conventional incandescent lamp decoration of always trying every means.
As everyone knows, LED under DC power supply, work can be maximum the advantage of having given play to high brightness.Yet, in the prior art, adopt full bridge rectifier need increase extra lead, rectifier diode is by independent placed apart, and/or need extra wire connection device, and/or need step-down to fall the stream device, influence the outward appearance of lamp string, and make rectifier diode produce overload, there is potential safety hazard.
Shown in Figure 1 is in the prior art, when the LED decorative chain comprises a LED series block just 4 of needs connect lead, at least 5 connections of needs lead just when comprising two or more LED series block.AC-DC conversion equipment and extra connection lead have all increased production cost and have influenced the aesthetic property of lamp string.
Fig. 2 A and 2B also are existing LED lamp string connection circuits.The characteristics of this technology are that the rectifier diode with rectification circuit is divided into two groups, are positioned over the two ends of lamp string respectively, thereby save lead, reduce cost.Yet, from Fig. 2 A, can see, when the lamp string does not have tail to insert, must include 3 leads and a virtual plug.And, if two groups of rectifier diodes placed apart and dropping equipment are and preceding insert or tail is inserted one and installed, insert before making or the slotting volume increase of tail, if insert or tail is inserted the words of partial installation with preceding, just need a bigger independently shell to hold them, these two kinds of outward appearances that structure all can increase manufacturing cost and influence the lamp string.
Can see that from Fig. 2 B the number of conductors in the circuit increases along with the increase of the LED series block of parallel connection, LED series block of every increase in the lamp string just increases a lead.Therefore, comprise the lamp string of 2 LED series block with regard to 4 leads of needs (3 LED series block are so analogized with regard to 5 leads of needs).So just need a sizable shell to remove to install a pair of rectifier diode, a plurality of terminal and dropping equipment.This technology has just lost the purpose of saving lead, has increased cost, has limited the design of lamp string, the outward appearance that has increased the complexity of manufacture process and had a strong impact on the lamp string.
In addition, in the circuit structure shown in Fig. 1, Fig. 2 A, the 2B, when increasing the LED series block, will produce danger.When increasing the LED series block, total load increases thereupon, and AC-DC converter this moment (rectifier diode) can heat up therefore and rapidly, causes danger.Therefore this two circuit structure all has strict restriction to the quantity of LED.
Summary of the invention
For solving the shortcoming of above-mentioned prior art, the purpose of this utility model provides a kind of rectification lamp string of uniqueness, and its improved circuit structure cost is low, simplified manufacturing process, increased the aesthetic property of lamp string, safe in utilization, broken through in the primary circuit structure restricted number to the LED lamp.
The purpose of this utility model is achieved in that a kind of rectification lamp string of uniqueness, includes:--preceding inserting with tail inserted, and connects by two parallel leads;--at least one LED series block;--corresponding each LED series block is provided with four rectifier diodes; It is characterized in that: described four rectifier diodes, wherein the negative pole of two rectifier diodes is connected with LED series block positive terminal respectively and contact at least one light-emitting diode that staggers, positive pole is connected with preceding two parallel leads slotting and that tail is inserted respectively, in addition the positive pole of two rectifier diodes is connected with LED series block negative pole end and contact at least one light-emitting diode that staggers, and negative pole is with preceding slotting and tail is slotting that two leads that walk abreast are connected.
A described rectifier diode is anodal to be connected with parallel lead, and negative pole is connected with the positive pole of first light-emitting diode of LED series block; Another rectifier diode is anodal to be connected with another parallel lead, and negative pole is connected with the positive pole of second light-emitting diode of LED series block; The positive pole of another rectifier diode is connected with the negative pole of last light-emitting diode of LED series block, and negative pole is connected with parallel lead; Another rectifier diode is anodal to be connected with the negative pole of LED series block penult light-emitting diode, and negative pole is connected with parallel lead.
Described two or more LED series block constitutes a long lamp string for being connected in parallel.
The utility model is inserted rectification circuit, the LED series block of inserting, include 4 rectifier diodes with tail before including the common decorative chain that connects by two parallel leads.In the circuit each independently rectifier diode be connected between lead and the LED series block, contact separates the diverse location that is distributed in the lamp string by the LED lamp.Respectively independently rectifier diode can disperse to be contained in lamp string plug, tail is inserted, the lamp housing of decorative chain, perhaps directly install and be connected (or in other assemblys) on light-emitting diode lamp socket or the lead, can simplify the making flow process like this, they are stashed, and need in the circuit structure without image pattern 14 rectifier diodes and a plurality of lead tie point are carried out sealed insulation.Perhaps need carry out sealed insulation to rectifier diode, voltage/current control apparatus and a plurality of lead tie point that is divided into two groups shown in image pattern 2A, the 2B.
Other LED series block can in parallel be connected with first LED series block, form lamp string structure and mounting means in parallel, so just eliminated the restriction of rectifier diode total current load in the prior art, eliminated the potential safety hazard that produces owing to overheated, and simplified manufacturing process.And, since the LED series block be parallel connection independently, therefore in a long lamp string, the LED quantity in each LED series block can be different.For example, series block # 1 contains 75 LED lamps, and Bing Lian series block # 2 contains 25 LED lamps with it, and series block #3 then contains 50 LED lamps.
Owing to number of conductors can not increase along with the increase of the LED series block of parallel connection, so manufacturing cost obviously descends, and the outward appearance of lamp string also makes moderate progress.A plurality of LED series block parallel connections need 5 leads among Fig. 1, and LED series block of every increase just increases a lead among Fig. 2 B.And the utility model what LED series block in parallel all only need 3 leads.
