Abstract: In his research Yulianov examines issues related to improving the process of designing lighting systems, in particular, moving from manually operated methods of design decision making to CAD automation of the process. The object of the research is the process of designing lighting systems. The subject of the research is the development of criteria and methods that can improve the lighting system design taking into account available technologies that are based on the dynamic change of the spectra. In particular, the author examines verification of design results by carrying out an on-site inspection of a facility using dedicated means. The author defines criteria of light environment that are subject to verification within the aforesaid process based on the systems analysis of existing and perspective concepts of lighting systems with spectral control. The result of the research is the conceptual description of lighting system verification methods based on the criteria offered by the author for evaluation the light environment. In prospect, these criteria will be available for lighting systems with spectral control. These methods can be used at certain stages of a service life of a facility considering that the iterative approach to lighting systems design has been undertaken. 

Abstract: The authors of the article examine issues related to increasing efficiency of computer-assisted design of lighting, in particular, transferring from design decision-making methods in the process of selecting lighting modes with the manageable spectrum based on the expert evaluation towards man-computer approaches. The authors of the given research apply the aforesaid approaches to one of the basic qualitative property of light emission, in particular, spectral radiant intensity. The authors describe methods for selecting optimal properties of artificial light sources as well as methods of their automated classification. In the process of their research the authors analyze methods of computer-aded analysis and optimization of the target function of the lighting spectral distribution based on application of widely used specialized programming language libraries Python. As a result of the research, the authors offer a conceptual description of two solutions that can be used in a complex process of manageable LED lighting operations design. The first solution allows to optimize the process of selecting the LED-based lamp RGB component emission power in case of approximation of the spectral distribution target function to the emission source. The second solution offers an automated classification of lighting sources depending on their spectral properties in order to prepare initial data for desinging or operating lighting systems. In conclusion, the authors analyze how these two solutions can be used in their combination within the framework of the systems approach and make suggestions about how these solutions can be developed further. 

Abstract: The object of the study is the process of computer-aided design of artificial lighting systems. The study was made on the possibility of improving its effectiveness through the application of the concepts of methods outlined in the article: automation the selection of operating modes of lighting devices with controlled emission spectrum, methods for optimizing the placement of lighting devices in particular by using specialized robotic complexes. In the paper the authors reviews problems the solution of which is caused by the development of technical progress in the field of lighting engineering and automation systems. The appearance of LED lamps with the possibility of automated control of lighting parameters as well as the availability of modern automation and robotics poses new challenges for design professionals and at the same time opens up new opportunities to reduce the amount of manual labor in the design process. In the course of the study, the existing solutions in the field of automated design of internal artificial lighting systems were analyzed. The system solution aimed at facilitating and increasing the efficiency of the processes of construction design is suggested. The result of the study is in conceptual description of three new methods aimed at improving the efficiency of CAD in construction. As the first method, the concept of automation of the procedure for preparing project solutions is presented. This concept is applied in terms of the choice of modes of operation of smart lighting systems, depending on the criteria for the specificity of the work in the room, the physiological impact and the specified indicators of the energy efficiency of the lighting system. The second method is the optimization of the procedure for automated placement of lighting devices in the development of appropriate design solutions. The third method is the concept of automatic survey of premises and the transfer of data to CAD to generate the initial data for the relevant design decisions. In the final part of the article, the method of combining these solutions within the framework of the system approach is considered and the assumption is made about the urgency of a more detailed elaboration of these solutions.
