| Abstract |
Fiber optic lighting system be set up of A and the B building.??It was cursed with many overall problems of sun-tracking, sensor, control, condenser, set position, fiber cable disconnection and so on.??Therefore, Progressed the photosensor exchange, program adjustment, repair of hardware for a solution of sun- tracking error. And also in fiber optical lighting systems it is a rule never to be used repaired glass fiber cable.??But in this study, because of the drop in efficiency of damaged cables the existing-cables is obliged?? to be repaired by the condition that is over 50% of the start efficiency.??Damage cables were repaired by cutting and polishing or connecting.??The result showed that intensity of illumination rate was improved 40% than the repair works before even if it decreased than initial 72% efficiency.??Accordingly 55% of system- efficiency was increased, on average.??Also accuracy of sun-tracking focus was improved about 96%. |
