method of measuring the fluorescence spectrum of the white LED device for phosphor and measuring device

摘要

PROBLEM TO BE SOLVED: To provide a measuring method of a florescence spectrum of a fluorescent body and a measuring device by which chromaticity management of a light emitting device using the fluorescent body is improved.;SOLUTION: A measuring method of a florescence spectrum of a fluorescent body which is used in a light emitting device by being dispersed in an encapsulation material, manufactures a sample 11 obtained by dispersing the fluorescent body in the encapsulation material, irradiates the sample 11 with irradiated light i so as to be transmitted, and measures the spectrum of fluorescence p by the fluorescent body to be emitted to the side where the irradiated light i is transmitted from the sample 11.;COPYRIGHT: (C)2013,JPO&INPIT
