For today the development in lighting technologies, in particular the creation of powerful extended and multicomponent sources, occupies a leading position in the field of innovation. The development of mentioned lighting devices is not possible without providing of careful control for parameters and characteristics both of the each source’s emitting element and of the entire lighting device as a whole. There are many various devices and measuring complexes, intended for verification and evaluation of extended and multicomponent light sources parameters and characteristics. However, none of them enables the simultaneous analysis of the spatial distribution of illuminance, color and spectral characteristics as well as power settings parameters of extended or multicomponent light sources. This problem can be solved by using of automated hardware and software complex for extended light sources verification, developed by the employees of the chair of optical-electronic devices and systems of St.-Petersburg national research university of information technologies, mechanics and optics in Russia. The paper presents the theoretical and practical aspects of the extended and multicomponent light sources spectral and color characteristics analysis as well as the results of illuminance distribution investigation in three-dimensional space for some kinds of light sources. In addition, we present the experimental results of several types of extended and multicomponent light sources with different shape, order and quantity of the emitting elements, spectral and energy characteristics of the radiation.
