LED조명 반사 스펙트럼이 적분구 광학 특성에 미치는 영향

다국어 초록 (Multilingual Abstract)

To measure optical properties of an LED lamp with a colored surface using an integrating sphere, its properties are influenced by not only the emission color of the lamp but also the color of the non-emitting surface. This study was conducted to evaluate the effect of the non-emitting color surface experimentally. The fluctuations of the optical properties according to the various colors and sizes of the non-emitting surface of the LED lamp were tested and analyzed in an integrating sphere as recommended in the IES LM-79-08. It is possible to correct the total luminous flux(TLF) less than 1.7%, the xy color coordinates 0.0014, the correlated color temperature(CCT) 62K, color rendering index(CRI) 0 even though the non-emitting surface area is up to 2.9% of the surface area of the integrating sphere. Through the calibration process it is possible to suppress the TLF to 5%, CCT 170K, CRI 1, while the non-emitting surface area is increased to 9.28% of that of the integrating sphere.
