In the paper the problem of an influence of properties of PCB on thermal and optical parameters of LED modules is considered. For some LED modules with the same project of mosaic made in PCB characterized by different parameters values, thermal and optical parameters are measured. The used measurement method is described and obtained results of measurements are presented and discussed. Some suggestions for designers of LED modules are formulated.
