FIG. 9 shows an LED lighting system 20 in the topology 1, 2, 2 (1 PS 10×2 DRV 36 (361 and 362)×2 LED lighting source 40 (401 and 402) commutation policy ending configuration LED lighting source 402 connected to PS 10 through DRV 362.
FIG. 9 shows an example LED lighting system 20, where a break in the circuit appears and is detected between the DRV 361 and the OS 37. As long as no break between the PS 10 and the IS 35 is diagnosed, the MCC 38 sends a message instructing the IS 35 to connect to a different spare DRV, DRV 362 from plurality of the DRV available (362) and the LED lighting source 401 fails to illuminate, LS 48 sends a message to the MCC 38, and the MCC sends a message instructing the OS 37 to connect to a different spare LED lighting source, LED lighting source 402 from plurality LED lighting sources (402) creating a new pathway PPW 4.
In FIG. 9, the DRV 361 becomes non-functional or defective, the next spare DRV 362 replaces the initially selected DRV 361; and LED lighting source 401 becomes non-functional or defective, the next spare LED lighting source 402 replaces the initially selected LED lighting source 401 to ensure LED lighting system 20 good operation and creating a new PPW 4:
PS 10>IS 35>DRV 362>OS 37>LED lighting source 402
