Energy saving in street lighting must meet specific technical requirements:
- adequate luminance of the road;
- uniformity of road luminance;
- limitation of glare from light centres;
- suitability as a sufficient visual guide.
The aim is therefore to achieve energy savings, with a consequent reduction in lighting costs, while always ensuring adequate visual comfort and avoiding over-lighting of areas.
In addition to the use of LED lamps, advanced lighting technologies such as presence and brightness sensors as well as automatic controls such as timers and luminous flux controllers must be used.
Quantum Srl develops lighting projects in the area of Saudi Arabia. It was responsible for upgrading all the street lighting in the province of al-Bāha, which is located in the south of the country, near Mecca.
For this type of intervention, Quantum uses GIS technology, thanks to which we integrate in a single environment the most common database operations (queries and statistical analysis) with the geographical analysis enabled by numerical cartography. Indeed, GIS allows a geographical entity to be analysed both for its complete geometric (and symbolic) nature and for its total information content.
In a challenging context, Quantum installed around 12,000 lighting points, effectively, punctually and efficiently illuminating an area of around 9921 km², upgrading and giving a new look to the territory.
