Functional lighting guarantees the adequate quantity of light required for comfort and to ensure the safe use of exterior areas, such as car parks, entranceways, passageways and paths. Diffused lighting is usually preferred to guarantee evenness in lighting all areas and surfaces. Access routes must be properly lit and direct or indirect glare should be avoided by performing thorough light engineering tests. It is therefore essential to assess the triangulation between an observer, the light source and reflective surface.
The light engineering design will then identify the perfect solution to make full use of the areas and routes within the reference settings, without altering the general look and lighting quality of all the areas. The use of direct lighting and LED light sources moreover ensures significant energy saving and reduced maintenance.
