Daylighting gets more attention as people seek better quality of light meanwhile saving electricity which in buildings. Fiberoptic based daylighting systems give us the freedom to provide natural light to any space in the building including north-facing rooms, basements, etc. Using plastic optical fibers (POFs) will significantly reduce costs for these systems. However, POFs are very sensitive to heat. The POF’s maximum operating temperature is 70℃. So, it is difficult to make a daylighting system using POFs that work stably in the long term. In this paper, a new method of eliminating the heat problem in POF-based daylighting systems was introduced. In the design, a UV-IR filter, a secondary optical element (SOE), and small silica optical fiber (SOF) bundles, were included so that the final temperature of the POFs becomes reduced to 56°C from 266℃ while the ambient temperature is 35℃. This result is promising enough for POF-based daylighting systems to be installed practically. Standardization of this method for a fiberoptic daylighting system will be implemented in the near future.
