The interior spaces that depend on their functional activities often evoke diverse receiving impressions that are embodied in different responses according to what the vocabulary and design elements emit according to the contradictory mechanisms of foundations and principles, as in the subject of amplification and reduction, and every duality is implicit in the meaning of these contradictions that enhance the sense of the luxury of the place and affect the use towards The optimal and appropriate performance, especially in the space of the public court hearings. On the other hand, the motives for the function of the interior space call for this design character when it requires a sense of the awe of the place and its activities, through regular geometric shapes abstracted from plankton of sense, addressing the imagination of the recipient with its physical and intellectual framework when imagination takes them To meditate on the interpretation of the luxury of forms borrowed from ancient architecture with a metaphysical tendency. Accordingly, the researcher finds the need to address this study and explore its origins and references, in order to be able to agree between the contradictions within the framework of a common field. Therefore, the researcher presents the problem of his research in the following question: How can a contradictory duality be used, such as amplification and reduction, to express the function of major internal spaces, while the thesis aimed at: First Finding contradictory conventions within the data of amplification and reduction that present design mechanisms with regular rhythms that call for everything that represents a sense of luxury, discipline and justice, and second: identifying the functional motives achieved by the expressive side in the elements of forms provided by both amplification and reduction within one design system, and the research reached results The most important of them: 1- The first model appeared in a modernist character away from stereotypes, so simplicity appeared in reducing the space of the interior space, the furnishing elements and the secondary ceiling in a circular shape. 2- The secondary ceiling and the industrial lighting units in the first model were characterized by a somewhat complex organization and cylindrical geometric formations, in contrast to the designer, the curves of their circular shapes in Floor tile inscriptions also appeared, while in the second model appeared square formations that harmonized with the shape and size of the interior space, The most important conclusions are: 1- Reducing the meaning of the identity of the place through geometric shapes with complex inscriptions and a civilizational allegorical character is of great importance to the societal and ideological feeling as expressive elements that enhance functional privacy that often calls for one common performance, values and belonging to unite the group,2-The role of amplification and reduction in expressing the function of the inner space comes from the quantities of the first and the qualities of the second, the optimal use depends on the correct reception.

The relevance of the introduction of HCL systems in production conditions, in which the dynamics of changes in the characteristics of light flux can be synchronized with the circadian biorhythms of the human body. This is determined by the fact that the unsatisfactory characteristics of industrial lighting increase the risk of injury and occupational morbidity. It is shown that providing only normative quantitative characteristics of illumination is not enough, since its qualitative characteristics – ripple coefficient, spectral composition cause non-visual effect of light. They can affect the psychophysiological state of a person, his\her performance, fatigue by affecting the circadian biorhythms of the body. The comparison of standard values of the level of artificial lighting of jobs in different countries with natural ones. Based on the analysis, recommendations were developed aimed at improving artificial lighting. The analysis of the results of the study of non-visual effect of the pulsation of the light flux on the psychophysiology of a person was carried out. Its main negative consequences are given, the necessary tasks for the implementation of the HCL program in a production environment in this aspect are identified. The results of analysis of studies of the influence of the color temperature of the light flux on the psychophysiological state of a person are also presented. Recommendations on the regulation of this parameter for various types of production activities have been developed.   Keywords: industrial lighting; NIF-effect; occupational injuries.

The issues of the visible lights non-visual impact on the human body during work, the circadian efficiency of lighting installations are considered, the analysis of fluorescent lamps used to illuminate industrial facilities according to their circadian characteristics is carried out, the need to take them into account when creating an effective industrial lighting installation is substantiated. Lighting systems design is one of the main components of the electric power systems formation for any industrial facility. When choosing equipment for the projects implementation, it is necessary to be guided not only by electrical parameters, but also by lighting technical parameters, since in addition to the power load, lighting is a means necessary for the successful implementation of the planned technological process. It is important to note that the illiterate implementation of the lighting network is a harmful factor and has a detrimental effect on the work and personnel health. Thus, ensuring light comfort, subject to the observance of the standardized illumination for each room, is one of the key tasks that must be solved when calculating and designing a lighting system. A properly designed lighting system has a direct impact on productivity, fatigue, visibility and visual discomfort during work. When choosing light sources to provide a given standardized illumination, various well-known calculation methods are used, but none of them takes into account the factors affecting the provision of visual comfort. The spectral composition of light is an important parameter of artificial light sources, which affects not only visual function, comfort, but also human health. When developing new lighting standards, standards for light sources and assessment of their quality, it is necessary to take into account the parameters that affect human health and well-being.

This abstract proposes a high brightness, high efficiency, dimmable LED driver based on linear current regulator technology for DC grid distribution systems. The proposed driver has excellent characteristics like the highest lumen per watt, long lifetime, high reliability, compact, low cost, both environmental and user-friendly which makes it suitable for lighting applications. Steady state and small-signal models of the proposed driver are performed which help in minimizing ground current and accurate compensator design, respectively. These two modeling approaches result in the optimization of both the footprint and cost of the driver. The performance of the proposed experimental prototype of the 20W driver is developed to validate the performance at different dimming levels and achieves maximum efficiency of 97%. The applications of the proposed converter are: dimmable home lighting system, advertisement boards and hoardings, industrial lighting systems, road transport indication lamps, indoor and outdoor stadium lighting, automatic street lighting, decorative systems, health appliances and auditoriums and many more.

The statistical data on the level of occupational injuries, which is caused by the discrepancy between the quantitative and qualitative characteristics of the working area illumination and the established stan­dards, are presented. The characteristics and features of the functioning of the human visual analyzer are described. Characterized by the non-visual effect of light on the human body. Developed recommendations on the organization of industrial lighting, which will provide a reduction in the level of occupational morbidity and industrial injuries.
