Referring to fig. 1, in an embodiment, the utility model discloses a wiring structure of LED carrier plate, its characterized in that:

the wiring structure is a three-wire system, and the wires are arranged only by utilizing the following three types of wires:

the first-class connecting wire is used for electrically connecting the power supply anode/VCC end of each LED luminous body in the first LED luminous body, the second LED luminous body and the third LED luminous body on the LED carrier plate;

the second-type connecting wire is used for electrically connecting the power supply cathode/GND end of each LED luminous body in the first LED luminous body, the second LED luminous body and the third LED luminous body on the LED carrier plate;

and the third type of connecting wire is used for electrically connecting the data signal input pin DIN end of each LED luminous body in the first LED luminous body, the second LED luminous body and the third LED luminous body on the LED carrier plate so as to provide data signals.

For the above-mentioned embodiment, the wiring structure is only a three-wire system, and the wiring for outputting the data signal is also eliminated compared with the wiring structure of break-through in the prior art. For fig. 1, the wiring and the plurality of LED luminaries are more illustrated, without the LED carrier plate.

Comparing fig. 1 with fig. 2, fig. 2 illustrates a wiring structure in the prior art:

although the controller of fig. 2 also uses only one DATA signal, i.e., DATA1, this point is seemingly the same as the only DIN one DATA signal shown in fig. 1 of the present invention, but:

in the order from right to left in fig. 2, it can be found that: in fig. 2, in order to implement the breakpoint resume function, DATA1 is directly connected to DIN1 pin of the first LED luminary and also connected to DIN2 pin of the second LED luminary, so as to ensure that the second LED luminary can still obtain the DATA signal from DATA1 through DIN2 pin even if the first LED luminary is not working normally and thus its DOUT cannot send out a valid signal. If the first LED emitter is operating properly, DOUT will forward a DATA1 signal processed by the first LED emitter and pass to DIN1 pin of the second LED emitter. And a third LED luminary, and the like.

It is apparent that for the prior art illustrated in fig. 2: the main pin for transmitting data signals is DIN1, and DIN2 plays a role of redundancy only when DIN1 cannot receive signals or works abnormally. Also, the signal of DIN1 is by default from DOUT of the preceding stage, and the signal of DIN2 is by default from DIN1 of the preceding stage. For a subsequent stage, the signal itself input in DIN1 of the subsequent stage is processed by a previous stage, so that the subsequent stage can directly acquire the data signal corresponding to the subsequent stage; or, the subsequent stage processes the signal input in DIN2 according to a fixed processing algorithm, and still enables the subsequent stage to obtain the data signal corresponding to the subsequent stage. In other words, even if the first LED luminary near the controller is not operating properly on the right side of fig. 2, the second LED luminary in the subsequent stage will also operate properly. And when the first LED luminous body and the second LED luminous body are in failure, the other rear stages have large-area failure. That is, with the wiring structure of the break-point continuous transmission scheme shown in fig. 2, if 2 consecutive illuminants or lines thereof fail, the corresponding subsequent stage will fail as a whole.

The utility model discloses compare the prior art that fig. 2 shows, can avoid falling DIN2 pin/terminal and corresponding wiring completely, because the utility model discloses only need arrange this kind of data signal circuit of DIN line can. Meanwhile, correspondingly, each LED luminous body has corresponding coding information, and the corresponding data signal aiming at the LED luminous body is obtained from the data signal only according to the coding information of the LED luminous body, so that the normal work of each LED luminous body is ensured. The prior art shown in fig. 2 does not rely at all on the coding of the LED luminary, but: or the data signal is processed by the preceding stage and then transmitted to the next stage through DOUT, or the next stage processes the signal according to DIN2 according to a fixed processing algorithm, acquires the data signal required by the stage, and continuously transmits the data signal backwards through DOUT. The coded information in the utility model refers to the address code information or ID code information of every LED luminous element to distinguish each LED luminous element, this information can be through OTP's mode or other burning record technique (based on floating gate, electric capacity silk or anti-fuse technique etc.) rigid storage in the LED luminous element, and change the state of relevant storage element with this solidification, rigid storage. In other words, all LED luminaries have different addresses or IDs based on the burning technology.

Just because the utility model discloses can avoid falling DIN2 this type of redundant pin and its wiring of connecting preceding stage DIN1 to and avoid removing the wiring that preceding stage DOUT is connected to back stage DIN1, and only adopt the three-wire system to connect all LED luminous bodies, so, the utility model discloses can show and reduce wiring complexity and wiring cost, also can show and reduce the fault rate and improve the yield. Typically, because the utility model discloses well third type connecting wire is as the data signal line, directly is connected with every LED luminous element's DIN, and every LED luminous element has its self coding information and the correct data signal who acquires self luminous element and correspond from the data signal line, and every LED luminous element self all connects VCC and GND that corresponds, so, after arbitrary one LED luminous element trouble, two continuous LED luminous elements or more break down even, the utility model discloses a wiring structure still can ensure the work of all the other luminous elements.

In addition, compare the utility model with the prior art shown in fig. 3:

the controller of fig. 3 adds a DATA signal, i.e., DATA2, compared to fig. 2, which is different from the DIN-only DATA signal shown in fig. 1 of the present invention. It is apparent that fig. 3 is more complex in wiring than the prior art of fig. 2, and is more susceptible to increased faults than the prior art shown in fig. 2.

To sum up, the utility model discloses can effectively reduce LED support plate wiring cost and improve the yield.

In another embodiment of the present invention, the substrate is,

each LED luminous body comprises coded information of the LED luminous body;

and each LED luminous body acquires a corresponding data signal aiming at the LED luminous body from the data signal according to the coding information of the LED luminous body.

In a further embodiment of the method according to the invention,

the LED carrier plate is made of a material with certain light transmittance.

A certain light transmission, for example near complete transparency or semi-transparency, depends on what visual effect the LED carrier is intended to achieve. Furthermore, need explain, because the utility model discloses a wiring quantity reduces, so corresponding solder joint will also reduce, to the LED support plate of same luminousness, the utility model discloses a transparency will further be improved to the LED support plate. Because the utility model discloses wiring quantity reduces, so under the prerequisite that satisfies the transparency, the utility model discloses compare prior art, more can improve the line width of wiring in the LED support plate in order to improve the ability of bearing the electric current.

In this case, the other side of the LED carrier board can be free from any components, for example, for attaching the LED lighting or display product using such wiring to a corresponding target.

In another embodiment of the present invention, the substrate is,

the circuits are arranged on two sides of the LED carrier plate.

It can be understood that, among them, the first-type connecting wires, the second-type connecting wires, and the third-type connecting wires may be respectively disposed on two sides of the LED carrier. Typically, when the LED carrier board is provided with the via holes, any one of the connecting wires can be freely arranged on two sides of the LED carrier board according to requirements, and even the connecting wires are connected through the via holes.

In another embodiment of the present invention, the substrate is,

(2) Each 2 LED carrier plates can be spliced into 1;

(3) The LED luminous bodies are connected in parallel.

For the above embodiment, the LED carrier can be designed to have a characteristic of arbitrary cutting/dicing, because 2 or more parts separated by cutting/dicing are cut/diced, each part still holds various connection lines in the circuit, and can be used for electrical connection of a certain number of LED illuminators. Therefore, only when the carrier board is cut/cut, the circuit function is normal, and the bearing function of the carrier board of the corresponding part is normal.

As for every 2 LED carrier plates can splice into 1, only need first kind connecting wire, second kind connecting wire, third kind connecting wire between two LED carrier plates electric connection each other can.

In addition, for each LED carrier plate, the LED luminous bodies are preferably connected in parallel, and the LED luminous bodies are more convenient to cut/cut and splice when connected in parallel. The parallel connection is preferred, which means that other connection modes are not completely excluded, and the basic voltage and current resistance requirements are met whether the connection modes are in series connection or in parallel connection or in series-parallel connection.
