[0050] figure 1 It is a schematic diagram of the lighting system according to the first embodiment of the present invention. figure 2 It is a signal waveform diagram of the lighting system according to the first embodiment of the present invention. Please also refer to figure 1 as well as figure 2, firstly, the first lamp control chip 111 first receives the first setting voltage, and the first setting voltage is a logic high potential, so the first lamp control chip 111 will set its own address as the first sequence, indicating that its It is located in the first one among all lamp control chips 111-119. Then, after one data slot, the second setting voltage will be converted to logic high potential by the first lamp control chip 111 to trigger the second lamp control chip 112 to set its address.
[0051] Since the position where the second setting voltage is converted into a logic high voltage is located in the initial data slot slot0, the second lamp control chip 112 wi...

[0073] The addressing modes in the first to Nth lamp control chips 311-319 can be implemented by firmware or circuits, which is not limited by the present invention. Take the circuit as an example, please refer to Figure 5 , Figure 5 It is a schematic circuit diagram of a lamp control chip according to the second embodiment of the present invention. in, Figure 5 Taking the first lamp control chip 311 as an example for illustration, the structures of the other lamp control chips are the same, which can be determined by Figure 5 Infer. Please refer to Figure 5 , the first lamp control chip 311 includes an address storage unit 510, a counter 520, a drive unit 530, a first switch 540, a second switch 541, and a shift register 550, wherein the counter 520 is coupled to the signal receiving interface 342, the first switch 540 , the second switch 541 , the output terminal 343 and the address storage unit 510 . The driving unit 530 is coupled to the address storage unit 510...

[0082] Image 6 It is a schematic circuit diagram of a lamp control chip according to the third embodiment of the present invention. in, Image 6 Taking the first lamp control chip 311 as an example for illustration, the structures of the other lamp control chips are the same, which can be determined by Image 6 Infer. Please refer to Image 6 , the first lamp control chip 311 includes an address storage unit 610, a counter 620, a drive unit 630, a multiplexer 640, a D-type flip-flop 650, a first switch 660, and a second switch 670, wherein the counter 620 is coupled to the signal The receiving interface 342 , the multiplexer 640 , the output terminal 343 , the first switch 660 , the second switch 670 and the address storage unit 610 . The driving unit 630 is coupled to the address storage unit 610 , the signal receiving interface 342 , the multiplexer 640 and the D-type flip-flop 650 .
[0083] Since the addressing method is the same as that of the above-mentioned second...
