FIG. 14 shows an LED lighting system 20 it appeared a break in the circuit and is detected between the DRV 361 and the OS 37, as long as no break between the power source PS 10 and the input selector IS 35 is diagnosed, the MCC 38 sent a message instructed the IS 35 to connect to a different spare DRV,DRV 362 from plurality of the DRV available (362,363) and the LLS 401 fails to illuminate, LS 48 sent a message the MCC 38 and this send a message and will instruct the OS 37 to connect to a different spare LED lighting source, LED lighting source 402 from plurality LLSs (401,402,403) creating a new pathway PPW 5:
In FIG. 14, the DRV 361 becomes non-functional or defective, the next spare DRV 362 was replaced the initially selected DRV 361, and LLS 401 becomes non-functional or defective, the next spare LLS 402 was replaced the initially selected LED lighting source 401 to ensure LED lighting system 20 good operation and creating a new PPW 5:
PS 10>IS 35>DRV 362>OS 37>LED lighting source 402
FIG. 15 shows an example LED lighting system 20 in the topology 1, 3, 3 (1 PS 10×3 DRV 36 (361 and 362 and 363)×2 LLS 40 (401 and 402 and 403) commutation policy ending configuration LLS 403 connected to PS 10 through DRV 362.
