There are many types of external area which need to be effectively lit, from urban centres, public amenity areas and shopping zones to subsidiary roads and car parks. These areas can vary widely in size and shape, demanding different patterns of light distribution whether the criteria is luminance or illuminance.
Illustrations of some of the Diamond Optic® settings are shown in the Flash movie below. You can select an example lighting application (eg. wide road) and try each of the sample Diamond Optic® settings (A,B,C,D,E and F) to see how the shape of the light distribution changes.
A highly flexible reflector system
The example illustrates the full flexibility, functionality and maximum efficiency that can be achieved with Diamond Optic®.
One luminaire type can be used throughout a multi-area scheme, with different Diamond Optic® settings, to create the optimal lighting performance for each area.
Rules of Thumb
The rules of thumb given on this page are intended as a starting point for lighting design calculations. Fine tuning and performance prediction should be calculated using our photometric data available on each of our product pages.
