Calculation of correction factor in PLS luminous flux measurement with integrating sphere

적분구를 이용한 PLS 광속측정의 보정계수 산출 및 적용

This paper describes the problem generated in PLS luminous flux measurement with integrating sphere. In RS case, we don't use the center position of the sphere but side position for flux test The difference of the lamp position makes the luminous flux difference of same light source. We confirmed the phenomenon with three other kinds of lamps and ensured the repeatability and reliability of this work at two laboratories. finally, the correction factor which should be applied for the PLS test at Side position was calculated.
