One of the most widespread relamping interventions is the conversion of sports lighting systems and light towers to LED.
Metal halide lighting fixtures on sports fields are typically 1,500 W and therefore are very expensive due to high energy absorption.
AIKO LED floodlights for sports facilities and for installation on lighting towers in large industrial areas are available from 220W to 1,200W with symmetrical and asymmetrical optics with customizable beam opening angles to distribute suitable light levels over an area of game and an area where men, machinery and goods move, all while reducing glare.
The AIKO offer is then completed with the modular and scalable wireless solutions for the automation and diagnostics of the devices installed on light towers based on the wireless Mesh Network technology, where each node receives, regenerates and retransmits the signals received thus allowing to extend the coverage area of the wireless network, exceeding the limit relating to the maximum transmission distance between two nodes. This allows you to create alternative routes to reach all the nodes of the system, making the system extremely robust even in the event of failure of some of the nodes installed.
What is required of a lighting system in a sports facility?
When designing the lighting of a sports field, be it indoor or outdoor, it is essential to put the comfort and performance of the players first and they should not be impeded by the lights nor should the ability of match officials to referee effectively.
A spectator should then be able to watch and enjoy the match without suffering any discomfort caused by the field lighting system which must also be able to respond to the needs of television broadcasters if matches of a certain importance are played.
The lighting system should also provide a long-term solution that is efficient and cost-effective in line with the latest regulations on environmental impact and sustainability.
The relevant lighting criteria from the point of view of sports lighting are:
- horizontal illuminance
- vertical illuminance
- uniformity
- limiting modeled glare and shadows
- light color and color rendering
What are the main reference standards?
The reference standards are UNI EN 12193 , relating to the lighting characteristics recommended for sports facilities, UNI EN 12665, the CEI 64-8 variant V2 standard (electrical public lighting systems) and, finally, UNI EN ISO 9001.
What are the requirements for outdoor large industrial area lighting?
The lighting of large external industrial areas such as goods sorting areas, transit areas for vehicles and people, outdoor storage areas, for the purposes of protectionist nature falls under the Consolidated Law on Safety at Work, Legislative Decree 81/08, in the broad concept of workplaces if pertaining to the company or production unit accessible to the worker in the area of his or her work.
The UNI EN 12464-2 standard of January 2008, Annex A, specifies the lighting requirements to ensure sufficient levels of visual comfort and visual performance for workers who carry out their work outdoors.
The UNI EN 12464-2 standard specifies the requirements for lighting in most outdoor workplaces and their related zones in terms of quantity and quality of lighting. To allow operators to carry out outdoor activities efficiently and accurately, especially during the night, adequate and timely lighting must be guaranteed. Lighting, degree of visibility and required visual comfort depend on the type and duration of the outdoor work activity.
For good lighting it is essential that, in addition to the lighting required, other needs of both a qualitative and quantitative nature are satisfied. The lighting requirements pass through the satisfaction of three basic human needs:
- visual comfort– when workers have a feeling of well-being, which, indirectly, also contributes to creating a high level of productivity;
- visual performance – when workers are able to perform their visual tasks, even under difficult circumstances and over long periods;
- security .
The main parameters to be considered in the design phase are: luminance distribution; the illuminance; the glare; intrusive light; the direction of the light; the color rendering and color appearance of the light; flicker and strobe effects; the maintenance factor; energy saving.
