Effects of Phosphor Concentration on Optical Properties of White Light LED Packages : Analysis and Measurement
碩士 === 長庚大學 === 機械工程學系 === 99 === The purpose of this study is to investigate the optical properties of PCLED (phosphor-converted light emitting diodes) with different phosphor concentrations. The Candela distribution and view angle of LED packages were measured by photo-goniometric. And the optical...
