The present invention relates to a light-emitting diode string system and method, in particular to a light-emitting diode string system and a sequencing method with a sequencing function.

A related art LED string system includes a related art LED driving device and a related art LED string; the related art LED string includes a plurality of related technologies Light-emitting diode lamps, these related art light-emitting diode lamps are electrically connected to each other. After the LED string of the related technology is manufactured, each LED lamp of the related technology has a local address code, and the local status of the LED lamp of the related technology The address codes are not the same, and the LED lamps of the related technologies are sequentially set according to the local address codes; for example, suppose the LED string of the related technologies includes 25 lights of the related technologies Diode lamps, the 25 LED lamps of related technologies respectively have the local address codes 01, 02...25, and the LED lamps of the 25 related technologies are sequentially in accordance with the Set the local address code 01, 02...25.

The related art LED driving device is used to drive the related art LED string to diversify light, and the method is as follows:

First, the related art LED driving device generates a related art driving light emitting signal, wherein the related art driving light emitting signal includes a predetermined address code and a light emitting code; then, the related art light emitting diode The body driving device transmits the driving light signal of the related technology to the LED lamps of the related technology, and all the light emitting diode lamps of the related technology receive the driving light signal of the related technology. If the local address code of the LED lamp of the related technology is the same as the preset address code of the driving light signal of the related technology, the LED lamp of the related technology emits light according to the driving of the related technology The light-emitting code of the signal emits light; if the local address code of the related technology LED lamp is different from the preset address code of the related technology driving light-emitting signal, then the related technology LED The lamp ignores the light-emitting code of the driving light-emitting signal of the related technology.

For example, if the predetermined address code of the driving light signal of the related technology is 05, then the light emitting diode lamp of the related technology with the local address code of 05 will emit light according to the driving light signal of the related technology. The code emits light, and other LED lamps of the related technologies ignore the light-emitting code of the driving light-emitting signal of the related technology. Therefore, the related art LED driving device can drive the related art LED string to diversify light.

When a LED of a related technology is damaged, the LED of the related technology will not emit light, and the user will purchase a new LED of the related technology and use the new related technology The LED of the technology replaces the damaged LED of the related technology. For example, when the related technology LED lamp with the local address code of 05 is damaged, the user will purchase a new related technology LED (for example, the local address code is 30), And replace the damaged LED with related technology (the local address code is 05) with the new related technology LED (the local address code is 30).

However, the related art LED driving device does not know that the new related art LED (the local address code is 30) has replaced the damaged related art LED (the original The status address code is 05), so that when the LED driving device of the related technology transmits the driving light emitting signal of the related technology with the preset address code of 05 to the LED lamps of the related technology, There is no LED lamp of any related technology that emits light according to the luminous code.

Therefore, when the related technology LED lamp with the local address code of 05 is damaged, the user can only purchase a new LED lamp of the related technology with the local address code of 05. And replace the damaged LED lamp with the related technology with the local address code of 05 with a new LED lamp of the related technology with the local address code of 05; or, the user only Can purchase a new LED string of the related technology to replace the original LED string of the related technology, which has the local address among the original LED string of the related technology The related art LED light code 05 is damaged. The user can not arbitrarily buy the related technology LED lamp whose local address code is unknown (or not 05) to replace the damaged LED lamp with the related technology whose local address code is 05.

In order to further understand the technology, means and effects of the present invention to achieve the intended purpose, please refer to the following detailed description and drawings of the present invention. I believe that the purpose, features and characteristics of the present invention can be obtained in depth and detail. It is understood that, however, the accompanying drawings are only provided for reference and illustration, and are not intended to limit the present invention.

In this disclosure, many specific details are provided to provide a thorough understanding of the specific embodiments of the present invention; however, those skilled in the art should know that in the absence of one or more of these specific details, The present invention can be practiced; in other cases, well-known details are not shown or described to avoid obscuring the main technical features of the present invention. The technical content and detailed description of the present invention are described as follows with the drawings:

Please refer to FIG. 1, which is a block diagram (parallel type) of an embodiment of the LED string system with sequencing function of the present invention. A light-emitting diode string system 10 with a sequencing function is applied to an AC power supply device 20; the light-emitting diode string system 10 with a sequencing function includes a light-emitting diode driving device 102 and at least one LED string 104; the LED driving device 102 includes a transmitter controller 108, a transmitter switch 110, a transmitter memory 112, a test button 114, a current detector 116, a The radio frequency receiver 118, the DC-to-DC converter 120, an AC-to-DC converter 122 and a first connector 168; the at least one LED string 104 includes a plurality of LEDs 106, a second Connector 170 and a third connector 172; the above-mentioned components are electrically connected to each other, and the light-emitting diode lamps 106 are electrically connected to each other (that is, connected in parallel), and the second connector 170 is Connect (for example, plug) to the first connector 168. The sending end memory 112 can also be integrated with the sending end controller 108 to form a controller with built-in memory.

After the at least one LED light string 104 is manufactured, each of the LED lamps 106 has a local address code, and the local address codes of the LED lamps 106 are different , And the LED lamps 106 are sequentially set according to the local address codes; for example, suppose that the at least one LED string 104 includes 25 LED lamps 106, and the 25 LED lamps 106 Each light-emitting diode lamp 106 has the local address codes of 01, 02...25, and the 25 light-emitting diode lamps 106 are sequentially in accordance with the local address codes 01, 02...25 in Figure 1 The middle is set from left to right.

The at least one LED light string 104 is connected to the LED driving device 102 through the first connector 168 and the second connector 170, and the LED driving device 102 is used to drive the At least one LED light string 104 diversifies light, the method is as follows:

The transmitter controller 108 controls the transmitter switch 110 (conducted or non-conducted) to generate a driving light emitting signal, wherein the driving light emitting signal includes a preset address code and a light emitting code; then, the light emitting diode drives The device 102 transmits the driving light-emitting signal to the LED lamps 106, and all the light-emitting diode lamps 106 receive the driving light-emitting signal. If the local address code of the light-emitting diode lamp 106 is the same as the preset address code of the driving light-emitting signal, the light-emitting diode lamp 106 emits light according to the light-emitting code of the driving light-emitting signal; If the local address code of the diode lamp 106 is different from the preset address code of the driving light-emitting signal, the light-emitting diode lamp 106 ignores the light-emitting code of the driving light-emitting signal; the above content can be called Point control technology.

For example, if the preset address code of the driving light-emitting signal is 05, the light-emitting diode lamp 106 with the local address code of 05 will emit light according to the light-emitting code of the driving light-emitting signal, and the other light-emitting The diode lamp 106 ignores the light-emitting code of the driving light-emitting signal. Therefore, the light-emitting diode driving device 102 can drive the at least one light-emitting diode string 104 to diversify light.

When a certain LED lamp 106 is damaged, the damaged LED lamp 106 will not emit light, and the user will buy a new LED lamp 106 and use the new LED lamp 106 106 replaces the damaged LED lamp 106. For example, when the LED lamp 106 with the local address code of 05 is damaged, the user will buy a new LED lamp 106 (for example, with the local address code of 30), and The new LED lamp 106 (with the local address code of 30) replaces the damaged LED lamp 106 (with the local address code of 05).

Therefore, two problems arise:

1. How does the LED driving device 102 know that the LED lamp 106 with the local address code of 05 is damaged (removed)?

2. How does the LED driving device 102 know that the local address code of the new LED lamp 106 is 30?

If the light-emitting diode driving device 102 learns that the light-emitting diode lamp 106 with the local address code of 05 has been removed, and if the light-emitting diode driving device 102 learns a new light-emitting diode lamp The local address code of 106 is 30, so next time the LED driving device 102 wants to drive the LED lamp 106 with the local address code of 05 to emit light, the preset position of the driving light-emitting signal The address code will become 30 (instead of 05).

In view of the above-mentioned first problem, the present invention provides a preset sequential test mode to help the LED driving device 102 find the damaged (removed) LED lamp 106. The content is as follows:

First, the test button 114 is pressed, so that the light-emitting diode driving device 102 enters the preset sequential test mode. When the light emitting diode driving device 102 is in the preset sequence test mode: the light emitting diode driving device 102 generates a plurality of preset sequence test signals, wherein each of the preset sequence test signals has the preset position Address codes, and the preset address codes are not the same; according to a test sequence of the preset address codes, the LED driving device 102 sequentially transmits the preset sequence test signals to the at least one light emitting diode The LED lights 106 of the LED string 104, and correspondingly and sequentially detect the consumption current of one of the at least one LED string 104; when the consumption current is less than or equal to a first current ( For example, 0mA or 0.001mA), the LED driving device 102 stores and defines the preset address code corresponding to the preset sequence test signal whose consumption current is less than or equal to the first current as a failure address code . Thereby, the LED driving device 102 can know which LED lamp 106 is damaged (removed).

For example, the preset sequence test signals respectively have the preset address codes 01, 02...25, and the test sequence is 01, 02...25; first, the light-emitting diode driving device 102 transmits the preset address code The predetermined sequence test signal with the address code of 01 to the LED lamps 106 of the at least one LED string 104; at this time, the LED lamp with the local address code of 01 106 will emit light to generate the consumption current (greater than the first current), so the LED driving device 102 knows that the LED lamp 106 with the local address code of 01 is normal.

Then, the light-emitting diode driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 02 to the light-emitting diode lamps 106 of the at least one light-emitting diode string 104; , The LED lamp 106 with the local address code of 02 will emit light to generate the consumption current (greater than the first current), so the LED driving device 102 knows that the LED lamp with the local address code is 02 The LED lamp 106 is normal.

And so on, until the light-emitting diode driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 05 to the light-emitting diode lamps 106 of the at least one light-emitting diode string 104 Since the LED lamp 106 with the local address code of 05 has been replaced, no LED lamp 106 will emit light, and the consumption current of the LED string 104 will be less than or equal to the first A current, so the LED driving device 102 knows that the LED lamp 106 with the local address code of 05 has been removed, the LED driving device 102 stores and defines (records) the preset Set the address code 05 as the invalid address code.

In a specific embodiment of the present invention, even if the LED driving device 102 learns that the LED lamp 106 with the local address code of 05 has been removed, the LED driving device 102 still Transmit the preset sequence test signals with the preset address codes of 06-25 to the LED lights 106 of the at least one LED string 104 before leaving the preset sequence test mode However, the present invention is not limited to this, once the LED driving device 102 knows that the LED lamp 106 with the local address code of 05 has been removed, the present invention can also leave the default Sequence test mode (that is, stop transmitting these preset sequence test signals). However, after transmitting the remaining preset sequence test signals, there is an advantage: if another damaged (removed) LED lamp 106 is found, the LED driving device 102 can raise an alarm. This informs the user that only one damaged LED lamp 106 can be removed at a time; that is, when the number of invalid address codes is greater than or equal to 2, the LED driving device 102 emits a warning signal .

In view of the above-mentioned second problem, the present invention provides an extended sequential test mode to help the LED driving device 102 find a new LED lamp 106. The content is as follows:

After the light-emitting diode driving device 102 completes the predetermined sequential test mode to leave the predetermined sequential test mode, the light-emitting diode driving device 102 enters the extended sequential test mode. When the light-emitting diode driving device 102 is in the extension sequence test mode: the light-emitting diode driving device 102 is used to generate a plurality of extension sequence test signals; each of the extension sequence test signals has an extension address code The extension address codes are not the same; the extension address codes are not the same as the preset address codes; the light-emitting diode driving device 102 transmits each of the extension sequence test signals to the at least one light-emitting diode Diode string 104, and respectively detect the consumption current of the at least one LED string 104; when the consumption current is greater than or equal to a second current (for example, 100mA or 200mA, greater than the first current) At this time, the LED driving device 102 stores and defines the extension address code corresponding to the extension sequence test signal whose consumption current is greater than or equal to the second current as a replacement address code. Thereby, the LED driving device 102 knows which LED lamp 106 is new.

For example, the extension sequence test signals respectively have the extension address code 26, 27...32; firstly, the light emitting diode driving device 102 transmits the extension sequence test signal having the extension address code 26 to the at least The LED lamps 106 of a LED string 104; at this time, since there is no LED lamp 106 with the local address code of 26, no LED lamp 106 will emit light. Therefore, the consumption current of the at least one LED light string 104 is smaller than the second current, so that the LED driving device 102 knows that there is no LED lamp 106 with a local address code of 26.

Then, the LED driving device 102 transmits the extension sequence test signal with the extension address code of 27 to the LED lamps 106 of the at least one LED string 104; at this time, because There is no LED lamp 106 with a local address code of 27, so no LED lamp 106 will emit light. Therefore, the consumption current of the at least one LED string 104 is less than the second current. The LED driving device 102 knows that there is no LED lamp 106 whose local address code is 27.

And so on, until the LED driving device 102 transmits the extension sequence test signal with the extension address code of 30 to the LED lamps 106 of the at least one LED string 104, because The LED lamp 106 with the local address code of 30 exists, so the LED lamp 106 with the local address code of 30 will emit light, and the current consumption of the LED string 104 Is greater than or equal to the second current, so the LED driving device 102 knows that the LED lamp 106 with the local address code of 30 has been added to the at least one LED string 104, the The LED driving device 102 stores and defines (records) the extended address code 30 as the replacement address code.

In a specific embodiment of the present invention, the present invention uses a current difference to detect new LED lamps 106; that is, when the LED lamps 106 are not on, a first Current; taking the above embodiment as an example, the extension sequence test signal with the extension address code 30 is transmitted to obtain a second current; and the second current minus the first current is equal to the current difference; if If the current difference is greater than or equal to a specific value (for example, greater than or equal to the above-mentioned second current), the light-emitting diode driving device 102 knows that the light-emitting diode lamp 106 with the local address code of 30 has been increased To the at least one LED string 104.

In a specific embodiment of the present invention, even if the LED driving device 102 knows that the LED lamp 106 with the local address code of 30 is new, the LED driving device 102 still transmits The extension sequence test signals with the extension address codes 31 to 32 respectively reach the at least one LED light string 104 before the LED lamps 106 leave the extension sequence test mode; however, this The invention is not limited to this. Once the LED driving device 102 learns that the LED lamp 106 with the local address code of 30 is new, the invention can leave the extended sequence test mode (ie, Stop transmitting these extended sequence test signals). However, after transmitting the remaining extended sequence test signals, there is an advantage: if another new LED lamp 106 is found, the LED driving device 102 can raise a warning signal to notify the user that only one time A new light-emitting diode lamp 106 can be added; that is, when the number of the replacement address codes is greater than or equal to 2, the light-emitting diode driving device 102 sends out a warning signal. Furthermore, the aforementioned extended address codes 31-32 are only examples, and the extended address codes 31-256, etc.

After the light emitting diode driving device 102 completes the extension sequence test mode to leave the extension sequence test mode, the light emitting diode driving device 102 replaces the invalid address code with the replacement address code in the test sequence. That is, the light emitting diode driving device 102 replaces the default address code 05 with the extension address code 30 in the test sequence, and the test sequence becomes: 01, 02, 03, 04, 30, 06 , 07...25.

Therefore, next time the LED driving device 102 wants to drive the LED lamp 106 with the local address code of 05 to emit light, the predetermined address code of the driving light emitting signal becomes 30 (instead of 05). ). Finally, in a specific embodiment of the present invention, the light-emitting diode driving device 102 can perform a re-confirmation action: the light-emitting diode driving device 102 sequentially transmits the predetermined sequence test signals (the test sequence is 01 , 02, 03, 04, 30, 06, 07... 25) to the LEDs 106 of the at least one LED string 104, and correspondingly and sequentially detect the at least one LED The current consumption of the body light string 104; if the current consumption is greater than the first current each time, the operation of replacing the invalid address code with the replacement address code is successfully performed.

For another example, the LED lamp 106 with the local address code of 06 is also damaged, and the user replaces the damaged LED lamp 106 with the local address code of 31 with another new one. The LED lamp 106 with the local address code of 06; in order to make the LED driving device 102 know that the LED lamp 106 with the local address code of 06 is damaged, and the damaged one has the original The LED lamp 106 with the address code of 06 is replaced by a new LED lamp 106 with the address code of 31. The content is similar to the above:

The test button 114 is pressed, so that the LED driving device 102 enters the preset sequence test mode; the preset sequence test signals will have the preset address codes as 01, 02, 03, 04, 30, respectively , 06...25, the test sequence is 01, 02, 03, 04, 30, 06...25; the position that was originally 05 has now been replaced by 30.

First, the light-emitting diode driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 01 to the light-emitting diode lamps 106 of the at least one light-emitting diode string 104; , The light-emitting diode lamp 106 with the local address code of 01 will emit light to generate the consumption current (greater than the first current), so the light-emitting diode driving device 102 knows that it has the local address code of 01 The LED lamp 106 is normal. Similarly, then the preset sequence test signal with the preset address code of 02, 03, 04 is sequentially transmitted; then, the preset sequence test signal with the preset address code of 30 Be transmitted.

Then, the light-emitting diode driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 06 to the light-emitting diode lamps 106 of the at least one light-emitting diode string 104. The LED lamp 106 with the local address code of 06 has been replaced, so no LED lamp 106 will emit light, and the consumption current of the LED string 104 will be less than or equal to the first current, Therefore, the LED driving device 102 knows that the LED lamp 106 with the local address code of 06 has been removed, and the LED driving device 102 stores and defines (records) the preset address Code 06 becomes the invalid address code.

After the light-emitting diode driving device 102 completes the predetermined sequential test mode to leave the predetermined sequential test mode, the light-emitting diode driving device 102 enters the extended sequential test mode. In the extended sequence test mode, since the extended address code 30 has been used, the extended sequence test signals will have the extended address codes 26, 27, 28, 29, 31, and 32 respectively.

First, the LED driving device 102 transmits the extension sequence test signal with the extension address code of 26 to the LED lamps 106 of the at least one LED string 104; at this time, because There is no LED lamp 106 with a local address code of 26, so no LED lamp 106 will emit light. Therefore, the consumption current of the at least one LED string 104 is less than the second current. The LED driving device 102 knows that there is no LED lamp 106 with a local address code of 26. Similarly, then the extended sequence test signal with the extended address code of 27, 28, 29 is sequentially transmitted; then, the extended sequence test signal with the extended address code of 31 is transmitted.

When the light-emitting diode driving device 102 transmits the extension sequence test signal with the extension address code of 31 to the light-emitting diode lamps 106 of the at least one light-emitting diode string 104, it has the local address The LED lamp 106 with the code 31 exists, so the LED lamp 106 with the local address code 31 will emit light, and the consumption current of the LED string 104 will be greater than or equal to the The second current, so the LED driving device 102 knows that the LED lamp 106 with the local address code of 31 has been added to the at least one LED string 104, the LED The drive device 102 stores and defines (records) the extended address code 31 as the replacement address code.

After the light emitting diode driving device 102 completes the extension sequence test mode to leave the extension sequence test mode, the light emitting diode driving device 102 replaces the invalid address code with the replacement address code in the test sequence. That is, the LED driving device 102 replaces the preset address code 06 with the extended address code 31 in the test sequence, and the test sequence becomes: 01, 02, 03, 04, 30, 31, 07 ...25. Therefore, next time the LED driving device 102 wants to drive the LED lamp 106 with the local address code of 06 to emit light, the preset address code of the driving light emitting signal becomes 31 (instead of 06). ).

Furthermore, each of the predetermined sequence test signals has a test light-emitting signal, and each of the extended sequence test signals has the test light-emitting signal. When the LED driving device 102 sequentially transmits the preset sequence test signals to the LED lamps 106 of the at least one LED string 104, if the LED lamps 106 are If the preset address code of the received preset sequence test signal is the same as the local address code of the LED lamp 106, the LED lamp 106 is based on the LED lamp 106 received The received test light signal of the preset sequence test signal emits light to generate the consumption current. When the LED driving device 102 transmits each of the extension sequence test signals to the LED lamps 106 of the at least one LED string 104, if the LED lamps 106 are The extension address code of the received extension sequence test signal is the same as the local address code of the light-emitting diode lamp 106, and the light-emitting diode lamp 106 is based on the information received by the light-emitting diode lamp 106 The test light signal of the extended sequence test signal emits light to generate the consumption current. Among them, in order to maximize the current consumption to help the above-mentioned current detection, the test light signal drives all the light-emitting diodes in the light-emitting diode lamp 106 to emit light; for example, if the light-emitting diode lamp 106 includes a A red light-emitting diode (not shown in Figure 1), a green light-emitting diode (not shown in Figure 1) and a blue light-emitting diode (not shown in Figure 1), then the red light-emitting diode, The green light-emitting diode and the blue light-emitting diode are driven together to emit white light.

Furthermore, the AC power supply device 20 transmits an AC power to the AC-to-DC converter 122; the AC-to-DC converter 122 receives the AC power and converts the AC power into a first DC power; The converter 122 transmits the first DC power to the DC to DC converter 120; the DC to DC converter 120 converts the first DC power into a second DC power; the DC to DC converter 120 transmits the first Two DC power supplies are connected to the LED driving device 102. The transmitter controller 108 controls the transmitter switch 110 (conducted or non-conducted) to generate the predetermined sequence test signals and the extended sequence test signals; the transmitter memory 112 is used to store the test Sequence, the invalid address code, and the replacement address code; the current detector 116 is used to detect the consumption current of the at least one LED string 104 to notify the sending end controller 108 of the For the consumption current of at least one LED string 104, the current detector 116 may include resistance elements, etc.; the radio frequency receiver 118 is used to receive a wireless remote control signal to control the transmitter controller 108. The third connector 172 is used to connect another light-emitting diode string 104. A plurality of the light-emitting diode string 104 connected in series can be controlled by a single light-emitting diode driving device 102 and connected in series. The number of the LED string 104 can be maximized according to demand and local power supply voltage.

The receiving end driver 128 is used to determine whether the extension address code of the extension sequence test signal received by the LED lamp 106 is the same as the local address code of the LED lamp 106; if the The receiver driver 128 determines that the extension address code of the extension sequence test signal received by the LED lamp 106 is the same as the local address code of the LED lamp 106, then the receiver driver 128 is based on The test light emitting signal of the extended sequence test signal received by the light emitting diode lamp 106 drives the first light emitting diode 156, the second light emitting diode 158, and the third light emitting diode 160 to emit light This consumption current is generated.

Please refer to FIG. 3, which is an external view of the light-emitting diode lamp of the present invention; the light-emitting diode lamp 106 is a light-emitting diode bulb to be installed on the lamp holder of the light-emitting diode string 104 Inside (not shown in Figure 3).

Please refer to FIG. 1 again, the third connector 172 is used to connect the second connector 170 of another light-emitting diode string 104; when a plurality of the light-emitting diode string 104 uses the first When the two connectors 170 and the third connectors 172 are connected in series, if a certain LED lamp 106 of a certain LED string 104 is replaced by a new LED lamp 106, the present invention The sequencing method includes the following:

First, the transmitter controller 108 knows the current consumption (for example, 125 mA) of a LED string 104 when the LEDs 106 of the LED string 104 are not on; therefore, When the LED string system 10 with sequencing function is connected to the AC power supply device 20, the LED driving device 102 does not drive any of the LED string lights 104 and uses the current to detect The detector 116 detects the current consumption to calculate the number of the LED light strings 104; for example, if the current consumption is 375 mA at this time, the number of the LED light strings 104 is 3 strings (375 /125=3).

Then, similar to the above method, but the above-mentioned current consumption standard becomes a multiple of the number of the LED light strings 104, for example, 3 times; therefore, for example, when only 2 times the above-mentioned consumption current standard is detected, The replaced LED lamp 106 can be found. Finally, the search for a new LED lamp 106 is the same as the above content, so it will not be repeated here.

In other words, in a specific embodiment of the present invention, the LED string system 10 with sequencing function includes N LED string lights 104, where N is an integer greater than 1. The N LED string lights 104 are connected in series. When the light-emitting diode driving device 102 is in a light string quantity detection mode: the light-emitting diode driving device 102 stops driving the light-emitting diode lamps 106 of the N light-emitting diode light strings 104 to emit light. Detect the current consumption of the N LED light strings 104, and calculate the number of the N LED light strings 104 as N based on this.

When the LED driving device 102 is in the preset sequence test mode: according to the test sequence of the preset address codes, the LED driving device 102 sequentially transmits the preset sequence test signals to The N LED string 104, and correspondingly and sequentially detect the consumption current of the N LED string 104; when the consumption current is less than or equal to N times the first current, the The light emitting diode driving device 102 stores and defines the default address code corresponding to the predetermined sequence test signal whose consumption current is less than or equal to N times the first current as the failure address code.

When the LED driving device 102 is in the extension sequence test mode: the LED driving device 102 transmits each of the extension sequence test signals to the N LED string lights 104, and correspondingly Respectively detect the consumption current of the N LED light strings 104; when the consumption current is greater than or equal to the second current, the light emitting diode driving device 102 stores and defines corresponding to the consumption current greater than or equal to the first The extended address code of the extended sequence test signal of the two currents becomes the replacement address code. The rest of the content is the same as before, so I won't repeat it here.

Please refer to FIG. 5, which is a block diagram of another embodiment of the LED string system with sequencing function of the present invention (series type); please refer to FIG. 8, which is the sequence function of the present invention The block diagram of another embodiment of the LED string system (series type). In FIG. 5 and FIG. 8, the light-emitting diode lamps 106 are connected in series with each other, and the rest of the content of FIG. 5 and FIG. 8 is the same as that described above, so it will not be repeated here.

Please refer to FIG. 6, which is a circuit block diagram of the LED lamp of the present invention (series type); the LED lamp 106 shown in FIG. 6 is applied to FIGS. 5 and 8. Each of the LED lamps 106 includes a voltage stabilizer 174, an oscillator 176, a signal conversion unit 178, an address and data identifier 180, a logic controller 182, a shift register 184, An output register 186, a light-emitting diode drive circuit 188, one-bit address register 190, one-bit address comparator 192, one-bit address memory 194, a first light-emitting diode 156, and a second Light emitting diode 158 and a third light emitting diode 160; the above-mentioned elements are electrically connected to each other.

Please refer to FIG. 7, which is a voltage and current curve diagram of the voltage stabilizer of the present invention; and please refer to FIG. 5, FIG. 6 and FIG. 8 at the same time; the voltage stabilizer 174 may be, for example, a susceptor diode. If the voltage stabilizer 174 is operating normally, the light-emitting diode lamp 106 operates to perform the luminescence or light emission of the first light-emitting diode 156, the second light-emitting diode 158, and the third light-emitting diode 160. No light (current consumption or no current consumption); the voltage change caused by such a current change is not large, so the current detector 116 will not be able to effectively detect the current consumption; for example, in Figure 7 Near the voltage VN, the voltage change corresponding to the first current interval R1 is not large.

In order to increase the voltage change, the voltage stabilizer 174 must stop operating; if the voltage stabilizer 174 stops operating, when the LED lamp 106 is on or off, the current change will cause a larger voltage change , So that the current detector 116 can effectively detect the current consumption to notify the sending end controller 108; for example, before the voltage VL in FIG. 7, the voltage change corresponding to the second current interval R2 is larger , Where the first current interval R1 is equal to the second current interval R2; obviously, the voltage change corresponding to the second current interval R2 is greater than the voltage change corresponding to the first current interval R1.

There are two ways to stop the regulator 174: one way is to reduce a driving voltage of the regulator 174 so that the regulator 174 stops operating; the other way is to stop the operation of the light-emitting diode driving device 102 A command signal is sent to the logic controller 182 so that the logic controller 182 turns off the voltage regulator 174.

In more detail, compared to the parallel mode, the series mode adds the regulator 174; the main purpose is to maintain each of the LED lamps 106 in the series path at a close voltage; The color of the LED lamps 106 is not necessarily the same, so the equivalent impedance is different, the voltage regulator 174 is adjusting this problem; this function will use the current difference to determine which position is not lit and the new position. The method of the lamp of the address code conflicts; therefore, when entering the detection mode, there are two ways to stop the regulator 174:

1. Before performing the preset sequence test mode and the extended sequence test mode, reduce the driving voltage of the voltage stabilizer 174, so that each of the light-emitting diode lamps 106 work in a state where the voltage stabilizer 174 is not turned on The voltage VL; that is, the regulator 174 is disabled.

2. Before performing the preset sequence test mode and the extended sequence test mode, the light emitting diode driving device 102 transmits the command signal to the logic controller 182 so that the logic controller 182 turns off the voltage regulator 174.

Furthermore, the other contents of the series type are the same as those of the above-mentioned parallel type. In addition, because the series type does not have the problem of reducing the high DC voltage to supply power to the electronic components in the parallel type, the integrated lamp beads can be used, and the series circuit is relatively simple.

Please refer to FIG. 4, which is a flowchart of the sequencing method of the present invention. A sequencing method of the present invention includes the following steps:

Step S02: A light emitting diode driving device executes a preset sequential test mode to detect a failure address code. Next, the sequencing method proceeds to step 04.

Step S04: The LED driving device executes an extended sequence test mode to detect a substitute address code. Next, the sequencing method proceeds to step 06.

Step S06: The LED driving device replaces the invalid address code with the replacement address code in a test sequence.

The execution of the predetermined sequential test mode by the light-emitting diode driving device includes the following: the light-emitting diode driving device generates a plurality of predetermined sequential test signals, wherein each of the predetermined sequential test signals has a predetermined Address codes, the preset address codes are not the same; according to the test sequence of the preset address codes, the light emitting diode driving device sequentially transmits the preset sequence test signals to a light emitting diode The light string is used to detect the current consumption of one of the light-emitting diode light strings, wherein in the test sequence, the preset address codes are arranged in order of magnitude, and the light-emitting diode light string includes a plurality of lights The LED lamps are electrically connected to each other (that is, can be connected in parallel or in series); if the consumption current is less than or equal to a first current, the LED driving device records the corresponding The preset address code of the preset sequence test signal when the consumption current is less than or equal to the first current becomes the invalid address code.

The execution of the extension sequence test mode by the light-emitting diode driving device includes the following content: the light-emitting diode driving device generates a plurality of extension sequence test signals, wherein each of the extension sequence test signals has an extension address code, The extension address codes are different, and the extension address codes are not the same as the preset address codes; the light-emitting diode driving device respectively transmits each of the extension sequence test signals to the light-emitting diode lamp String to detect the consumption current of the light-emitting diode string; if the consumption current is greater than or equal to a second current, the light-emitting diode driving device records the extension corresponding to the consumption current being greater than or equal to the second current The extended address code of the sequential test signal becomes the replacement address code.

Among them, each of the light-emitting diode lamps has a local address code; the local address codes are not the same; each of the preset sequence test signals has a test light signal; each of the extended sequence test signals It also has the test light signal. When the light-emitting diode driving device sequentially transmits the preset sequence test signals to the light-emitting diode lamps of the light-emitting diode string, if the light-emitting diode lamp receives the preset The preset address code of the sequence test signal is the same as the local address code of the LED lamp, and the LED lamp is based on the preset sequence test signal received by the LED lamp The test light signal emits light to generate the consumption current. When the LED driving device transmits each of the extension sequence test signals to the LED lamps of the LED string, if the extension sequence received by the LED lamp is The extended address code of the test signal is the same as the local address code of the LED lamp, then the LED lamp emits light according to the test signal of the extended sequence test signal received by the LED lamp The signal emits light to generate the consumption current.

The remaining content of the sequencing method of the present invention is similar to the foregoing content, which is a brevity factor, so it will not be repeated here.

The effect of the present invention is to enable the new LED lamp to replace the damaged LED lamp to correctly emit light according to the content of the driving light-emitting signal.
