Dynamically variable luminance distribution as the method of designing and architectural floodlighting

The article describes a new author's method of floodlighting designing of architectural objects. The method is described and the advantages and limits are shown. The method allows to create a multivariate concept of illumination without the need of usage of complex visualization tools. It is based on projections on the real object of the 3D model or two-dimensional grid, the luminance distribution image. This distribution can be implemented by currently produced lighting equipment, as well as by the modification of this equipment or the new one, not produced yet or being in production phase. The luminance distribution is created by a lighting designer in real time. The image display is realized by system comprising a PC, computer application and a multimedia projector. The luminance distributions modified in application or new created, allow to generate a computer application photometric files. These files are the basis for selection from the lighting equipment base luminaires carrying out luminance distributions similar to the intended ones. It is also possible to design new luminaires, which fulfill required luminance distributions. The result of this method is complete technical documentation of lighting equipment used for the specific lighting solution.
