為延續本研究團隊在高功率發光二極體(LED)光學特性的研究成果，將進一步探討LED的發光光譜特性，以做為標準光源之方法。期能藉由將LED的發光光譜特性予以最佳化的過程，訂出一系列由相關色溫決定的結果，得到與標準A光源、標準D光源的相類似程序，為LED固態照明光源的發光特性，決定出一可靠的方法，使得LED固態照明光源能有列入標準光源成為標準光源L的可能性。同時，除了在分析理論方法上找到一可行的程序之外，在實務上也希望能夠得到此標準化光譜的照明光源實現。因此，在第二階段，也將利用過去所發展的LED光譜組成技術，實現此項具色溫可調之標準光譜的LED光源，以供實際應用之需求，如標準檢測、光度/色度標準比對、量測校正等，發揮LED照明光源的更大效用。 ;To extend our study on the optical properties of the high power LEDs, we would like to explore with the spectral properties of the LED solid-state light sources. By the optimization process on the LED illuminating spectra, we will determine a series of optimal LED spectra which are dependent on the correlated-color temperature only. Similar to the standard illuminant A and the standard illuminant D, some solid process will be developed to determine the optimal LED spectra in a simple way such that the new standard illuminant L becomes possible and promising. In the second stage of this project, we will make effort on the realization of this LED light source with the CCT-dependent optimal spectrum. Based on our previous research results, we believe that a CCT-tunable light source with designed illuminating spectrum is possible to be made from one appropriate set of LEDs. In such a way, the LED solid-state light source can march into many more practical applications like the standard measurement, photometry/colorimetric calibration, instrument calibration, and so on.
