ALUMINIUM OPTICS RANGETo achieve differ<strong>en</strong>t op<strong>en</strong>ing angles, at <strong>ROVASI</strong>’s technicaldepartm<strong>en</strong>t we are working on five differ<strong>en</strong>t types of reflectorfinish. In this way, we manage to cover the following op<strong>en</strong>ingangles.It is very important that the reflectors are highly effici<strong>en</strong>t, do notcause colour changes, allow uniform lighting distribution and<strong>en</strong>sure a high level of visual comfort.Beam angle types:10º - 19º: spot - SP20º-29º: narrow flood: NFL30º-39º: flood: FL40º-69º: wide flood: WFL>70º: very wide flood: VWFLAsymmetrical light distribution:POLAR DIAGRAM AND ISOLUXIn the catalogue the following photometric details of the luminaires are available: beam angle, LOR, UGR and their polar or isoluxcurves.Polar curve, is a graph showing how luminous int<strong>en</strong>sity valuesvary with increasing angles from the imaginary axis of theluminaire. The unit of light int<strong>en</strong>sity is Candela (cd).Isolux diagram repres<strong>en</strong>ts illuminance distributions, where asingle refer<strong>en</strong>ce plane is shown with contours superimposed.The contours provide the points of equal illuminance, infootcandles or lux, on the floor or wall plane, from a specificstated mounting position. The diagram can be used to assessthe distribution characteristics of the luminaire in additionto determining lighting levels. The luminaire is positionedc<strong>en</strong>trallyabove (0,0) of the grid and all distances on the grid arein metres.For further information you can download the technical details of the refer<strong>en</strong>ces from the www.rovasi.com website. There you willalso find the EULUMDAT and IES files and those for calculating lighting with the main lighting programs.GENERAL INFORMATION97
