Abstract

Industrial facilities such as production and storage halls are a specific environment, which is usually characterized by a large usable area, which is managed in a way that brings together in the given area many functional zones for various purposes. Frequent changes in the management of industrial halls gives a need to change the lighting method. In such a situation, a lighting solution that enables the photometric characteristics of the luminaires to be adapted to variable development of the facility, covering not only the quantitative regulation of the luminous flux, but also the direction of its radiation into the environment, can be a helpful solution. The article presents an innovative concept of a luminaire, which makes it possible to change the light distribution without the need to replace optical elements. Simulation tests were carried out for the developed luminaire in order to check the possibility of obtaining the assumed distribution and shapes of light spots on the working plane. Thanks to the application of this solution in an environment where there is a need for frequent changes in the development of usable space requiring changes in lighting conditions, it is possible to dynamically adjust the characteristics of the installed system to new environmental conditions.
