The paper presents the results of investigations of the spatial radiation patterns of selected solid state light sources. A system for measuring such characteristics, developed and constructed by the authors, is described. Spatial radiation patterns are measured for selected light sources. Based on the measurement results, values of the luminous flux emitted by the light sources under consideration are determined. The obtained measurement results are discussed.
