Effects of dynamic lighting on human health

Characteristics of the preferred light source must be known and optical, thermal and electrical performances must be determined while the design of lighting fixture. Considering economic parameters, the geometry of space and needs should be analyzed, in making the appropriate lighting design project. Besides all with the light comes to eye does not occur only the act of seeing. Also biological system is affected, circadian system is balanced, people?s living and working conditions are changed.Dynamic lighting, getting to know lighting environment that is needed, having accordance with continuos changing structure and control mechanism form of lighting design. Dynamic lighting which is moving the dynamism of daylight to indoors, creates `natural? light that supports to people?s mood. In this way, not only provide energy savings and increase energy efficiency but also allows people to feel good about themselves as compatible bioritm.Melatonin secretion is related to the ambient light level. Secretion of melatonin effects on sleep-wake pattern and working the immune system. In this sense lighting has ceased to be the only in designing and in engineering, has become a subject of research and practice in architecture, in psychology and in medicine.The aim of performed application is to determine the effect on human and intended use of dynamic lighting.In order to provide beter quality of living and working environments, to handle relationship between light and health at stages of design and application shall be suited.
