Within the framework of thesis my work is the participation in development of the complex solar rating system in the Department of Electron Devices. I look over the parts and the system design of the previously completed system, with extraordinary regarding on the extant solutions of the lighting part. I have to design a modularity lighting part, taking into consideration the previously lighting intensity and light distribution simulations. The luminosity of the lighting module must be adjustable. The homogeneity of the lighting module must answer to the IEC 60904-9 Class “A“ regulation. The assembled modular system must match to the nowadays using solar board. In the favor of right cooling the single modules have to implant to the metal core printed circuit board. I have to do a proposal to the unified supply and regulation of the module. I have to devise a conception for the modularity and the mechanical fixation of the module. I have to build a module and I have to perform the characterization of the module.
