Simple method of measuring photometric and radiometry parameters of power LEDs

Abstract

In the paper a new and easy to realize manner of measuring values of important photometric and radiometry parameters of power LEDs: the luminous flux and the power of optical radiation is proposed. The idea of measurements and the manner of its practical realization are presented. The usefulness of the proposed method is verified experimentally for the selected types of power LEDs. Factors restricting the accuracy of this method are discussed.
