Reverse luminous intensity calculations for lighting system optimisation

Reverse luminous intensity calculations for lighting system optimisation

Konferenční sborník (ne stať)

This paper deals with inquiry of reverse lightening calculation used for lighting design and optimisation of lighting system. In practice, there is usually the use of principles of step-by-step approximation and looking for desirable luminaries by experiment-miscue method. It is usually presented as a very uneconomical way of work, which is slow, producing not the best results and weight on the final design by inefficient costs on lighting working. It is true, that direct lightening calculation from luminaries to working areas direction, is deterministic and simply algorithmized. In opposite, reverse calculations, thought from illuminated area to luminaries, i.e. looking for desirable curve of luminous intensity, don’t go to unique results and it is required to add rules, which assure convergent calculation. In this document, the presented information is focused on basic delimiting of reverse lightening photometric calculation targets and disquisition about problems of use of this calculation in a practice. On the other side, utilization of reverse analyse principles is a theme of so-called reverse engineering, which is commonly used in many branches today, especially in a machine, an electrical circuits and software development. It could be surely interesting to implement the analytical tools also into the software for the lighting calculation.
