Paper Abstract

The paper presents the technique and instrumentation for fully automatic measurement of angular intensity distribution of a light emitting diode (LED). The analysis of important factors that influence to measurement accuracy is done and algorithms for their minimization are identified. As a result the technique makes possible intensity measurements with angular spatial error smaller than 1 angular degree in half sphere with relative error of intensity registration smaller than 1%. The presented measuring system performs all operations automatically under computer control, generates the protocol of measurements with 3D diagrams of intensity distribution and makes conclusion how LED corresponds to its technical specification.
