Modelling Of Large Light Sources Radiation To The Upper Hemisphere - Obtrusive Light
Original language description
This article describes one possible way of conducting evaluation of lighting system in aspect of influence of emitted luminous flux on outdoor environment in upper hemisphere. It is focused on modelling, evaluation and limitations of obtrusive light on practical/everyday examples and applications. Nowadays information and discussions stimulated research to find "simple" model of radiation of luminous flux to the upper hemisphere. It means that the model will evaluate luminous flux (direct and reflected) not only generally, but to the affected directions too. The contribution describes how the model works. There is description of basic calculations of luminous flux radiation characteristic. Last parts of contribution try to shows example of real town lighting systems. Modelled example shows calculations of different lighting system like public lighting, billboards, windows and cars separately.
