Description

Multichannel combination LED decorative chain

Technical field

The utility model relates to LED lamp string design application, the LED decorative chain that particularly a kind of multichannel is connected.

Background technology

Decorative chain (like Christmans light string) is normally combined by LED monochromatic (red, yellow, blue, green, white, letter out) or lampion string and LED lamp series controller; Can produce multiple light variation effects such as Chang Liang, gradual change, flicker, the LED number on lamp string length, way, each road can customize according to specific requirement.The basic function of LED lamp series controller chip comprises: driving LED lamp string, the light changing pattern of LED lamp string is controlled.Can adopt various mode is that LED lamp string provides power supply, if the solar energy Christmans light string, its LED lamp series controller chip also comprises photosensitive control circuit or the like.Fig. 1 is an example with simple 2 the tunnel, and the traditional LED lamp string and the method for using of controller chip thereof have been described.Among the figure, n is the LED number on each road, can customize according to specific requirement, and representative value is 50,100, and what quantity was many reaches 200,500 even more.Fig. 2 has provided the local control of 2 traditional paths of LEDs lamp series controller chip internals sketch map.Switch1, switch2 are 2 pins of LED lamp string control chip, and sheet connects the negative pole of the first via and the second paths of LEDs lamp string outward respectively, provide the driving tube of drive current to be communicated with through switching tube with giving LED lamp string respectively in the sheet.Switching tube receives the control of the concrete lamp light mode control circuit of chip internal, when Switch1 is communicated with driving tube through switching tube, and when the first paths of LEDs lamp cross luma, Switch2 are communicated with driving tube through switching tube, the second paths of LEDs lamp cross luma.2 paths of LEDs lamp strings need 3 lines, normally copper cash.

The LED number on each road is many more, and the copper cash coiling is long more, and processing is trouble more, and copper cash need be thick more, to reduce the pressure drop of LED drive current on copper cash.Copper cash is long more thick more, and cost is high more, and it occupies suitable proportion in whole LED Christmans light string product, and proportion is high nearly reaches 50%.

More than in needed 3 lines of 2 paths of LEDs lamp strings, the positive pole of all LED connects single line, promptly meets VDD, in addition, the negative pole of first paths of LEDs connects single line, connects the Switch1 pin of chip, the negative pole of second paths of LEDs connects single line, connects the Switch2 pin of chip.In the process, note distinguishing each root line, in case the VDD line corresponding with Switch1 or Switch2 connects instead, will cause the product cisco unity malfunction, this has certain influence to production efficiency.

Fig. 3 is the traditional 4 paths of LEDs lamp strings and the method for using sketch map of control chip thereof; Its method of attachment and operation principle and 2 tunnel similar; Need altogether 5 copper cash, one meets power vd D, other four respectively with 4 pins (Switch1/2/3/4 links to each other) of LED lamp string control chip.Chip internal receives the control of concrete lamp light mode control circuit, Switchk (k=1,2,3,4) through switching tube when providing the driving tube of drive current to be communicated with for LED lamp string, k paths of LEDs lamp cross luma.

The utility model content

The purpose of the utility model is to provide a kind of multichannel combination LED decorative chain, and the reduction product cost is also enhanced productivity.

For reaching above purpose; The solution that the utility model adopted is: a kind of multichannel combination LED decorative chain; It comprises lamp string location and the lamp string control chip of being made up of 2 paths of LEDs lamp strings; It is characterized in that: in described lamp string location; The negative pole of the positive pole of the first paths of LEDs lamp string and the second paths of LEDs lamp string connects first pin of lamp string control chip through first copper cash, and the positive pole of the negative pole of the first paths of LEDs lamp string and the second paths of LEDs lamp string connects second pin of said lamp string control chip through second copper cash, and said first pin is connected with the output of the inner dual tr tube of said lamp string control chip respectively with second pin; Two inputs of said dual tr tube are connected with the driving tube output with power end respectively, and the control end of said dual tr tube is connected with lamp light mode control circuit output.

Said lamp string location has many groups, formation multichannel lamp string parallel with one another between them, and each street lamp polyphone is connected to identical pin and controls jointly; Or every group of lamp string location connect the pin of other lamp string control chip separately, forms multichannel lamp string and control separately.

Owing to adopted such scheme; The utlity model has following characteristics: the LED lamp string of the utility model and the method for using of control chip thereof; Under the constant condition of LED lamp string way, reduce the radical of the copper cash that uses, thereby reduce the coiling time significantly and reduce finished product.Simultaneously, with 2 paths of LEDs lamp string standard modular, can be combined into LED multi-path lamp string easily through calling these standard modules, easy to process, production efficiency further is greatly improved.
